Attenuation of mu-opioid tolerance and cross-tolerance by the competitive N-methyl-D-aspartate receptor antagonist LY235959 is related to tolerance and cross-tolerance magnitude. (1/99)

Although NMDA receptor antagonists attenuate the development of morphine tolerance, it is not clear whether NMDA receptor antagonists also prevent tolerance and cross-tolerance to other mu-opioid agonists and, if so, whether prevention is related to the efficacy of the agonist used to examine tolerance. A rat tail-withdrawal procedure was used to test the antinociceptive effects of the mu-opioids etorphine, morphine, and dezocine before and after twice-daily subcutaneous injections with either 0. 003 mg/kg etorphine, 10 mg/kg morphine, or 3.0 mg/kg dezocine, each administered alone or in combination with 3.0 mg/kg of the competitive NMDA antagonist LY235959. After chronic etorphine, the etorphine, morphine, and dezocine curves were shifted rightward 1.0-, 2.2-, and 3.4-fold, respectively. LY235959 prevented cross-tolerance to morphine and dezocine. After chronic morphine, the etorphine and morphine curves were shifted rightward 2.5- and 2. 9-fold, respectively, and the dezocine curve was flattened. LY235959 prevented morphine tolerance and cross-tolerance to etorphine and reduced the magnitude of cross-tolerance to dezocine. After chronic dezocine, the etorphine, morphine, and dezocine curves were shifted rightward 4.1-, 3.5-, and 9.6-fold, respectively. LY235959 did not prevent but reduced the magnitude of tolerance and cross-tolerance. In a separate experiment, the following rank order of efficacy was determined from the magnitudes of rightward shift in each dose-effect curve after administration of 1.0 mg/kg of the irreversible antagonist clocinnamox: etorphine > morphine > dezocine. These data show that differences in tolerance magnitude are related to opioid efficacy and that attenuation of mu-opioid tolerance and cross-tolerance by LY235959 depends upon the magnitude of opioid tolerance.  (+info)

Particulate matter and manganese exposures in Indianapolis, Indiana. (3/99)

The distribution of PM(2.5) and manganese (Mn) personal exposures was determined over a 4-month period in Indianapolis, IN, at a time when the gasoline additive, methylcyclopentadienyl manganese tricarbonyl (MMT), was not being used. The data collection period coincided with the data collection period in the Toronto, ON, study, where MMT had been used as a gasoline additive for over 20 years. The inferential or target population consisted of noninstitutionalized residents of the Indianapolis area during the monitoring period (from May 1996 through August 1996) who were at least 16 years old. The survey instruments used in this study (and also in Toronto) included a household screener form (HSF), a study questionnaire (SQ), and a time and activity questionnaire (TAQ). The SQ was administered to elicit information about the participant and his/her activities, occupation, and surroundings that might be relevant to his/her exposure to particles and Mn. In addition to the personal particulate matter (PM) and elemental 3-day monitoring, 240 participants completed a TAQ on a daily basis during the actual monitoring period. Also, a subset of participants had 3-day outdoor and indoor stationary monitoring at their home (approximately 58 observations), and sampling was conducted at a fixed site (approximately thirty-three 3-day observations). The quality of data was assessed and compared to the Toronto study in terms of linearity of measurement, instrument and method sensitivity, measurement biases, and measurement reproducibility. Twenty-six of the sample filters were subjected to two analyses to characterize the within-laboratory component of precision in terms of relative standard deviations (RSDs). The median RSD for Mn was 8.7%, as compared to 2.2% for Toronto. The quality assurance (QA) laboratory exhibited a clear positive bias relative to the primary laboratory for Al and Ca, but no systematic difference was evident for Mn. A high interlaboratory correlation (>0.99) was also attained for Mn. Mean field blank results for PM and Mn were 0.87 microg/m(3) and 0.71 ng/m(3), respectively, which were comparable to the Toronto study. The median RSDs for colocated fixed site and residential samples ranged from 2.2% to 9.0% for PM and from 8.8% to 15.3% for Mn, which were close to those observed in Toronto. For the PM(10), the 90th percentile indoors was 124 microg/m(3) compared with 54 microg/m(3) outdoors. This pattern was even more pronounced for the PM(2.5) data (90th percentiles of 92 microg/m(3) indoors vs 30 microg/m(3) outdoors). Personal PM(2.5) was somewhat higher than the indoor levels, but the percentiles seemed to follow the more highly skewed pattern of the indoor distribution. This difference was largely due to the presence of some smokers in the sample; e.g., exclusion of smokers led to a personal exposure distribution that was more similar to the outdoor distribution. The estimated 90th percentile for the nonsmokers' personal exposures to PM was 43 microg/m(3) compared with 84 microg/m(3) for the overall population. In general, the Indianapolis PM levels of a given type and cut size were somewhat higher than the levels observed in Toronto, e.g., the median and 90th percentile for the personal PM(2.5) exposures were 23 and 85 microg/m(3), respectively, in Indianapolis, while in Toronto, the corresponding percentiles were 19 and 63 microg/m(3). The cities' distributions of the proportion of the PM(10) mass in the 2.5-microm fraction appeared similar for the residential outdoor data (medians of 0.67 and 0.65 for Indianapolis and Toronto, respectively, and 90th percentiles of 0.83 for both cities). For the indoor data, Indianapolis tended to have a larger portion of the mass in the fine fraction (median of 0.80 compared to 0.70 for Toronto). Unlike the PM, the Indianapolis indoor Mn concentration levels were substantially lower than the outdoor levels for both PM sizes, and the median personal levels for Mn in PM(2.5) appeared to fall between the median indoor and outdoor levels. The personal Mn exposure distributions exhibited more skewness than the indoor or outdoor distributions (e.g., the means for the personal, indoor, and outdoor distributions were 7.5, 2.6, and 3.5 ng/m(3), respectively, while the medians were 2.8, 2.2, and 3.2 ng/m(3), respectively). At least a substantial portion of the high end of the personal exposure distribution appeared to be associated with occupational exposures to Mn. In general, the Mn levels in both cut sizes in Indianapolis were approximately 5 ng/m(3) smaller than those in Toronto (e.g., the estimated median and mean levels for personal Mn exposures in PM(2.5) were 2.8 and 7.5 ng/m(3), respectively, in Indianapolis, but were 8.0 and 13.1 ng/m(3) in Toronto). For the nonoccupational subgroups with no exposure to smoking and no subway riders in the two cities, the medians (2.6 ng/m(3) in Indianapolis and 7.8 ng/m(3) in Toronto) were similar to those for the overall populations, but the means were substantially smaller (3.1 ng/m(3) in Indianapolis and 9.2 ng/m(3) in Toronto). The median proportion of Mn in the fine fraction (relative to the PM(10) Mn) for Indianapolis was 0.39 for outdoors and 0.55 for indoors; these ratios were somewhat smaller than the corresponding Toronto medians (0.52 and 0.73). The study found high correlations for particulates and Mn between personal exposures and indoor concentrations, and between outdoor and fixed site concentrations, and low correlations of personal and indoor levels with outdoor and fixed site levels. The pattern was similar to that observed for Toronto, but slightly more pronounced. The PM(10) Mn concentrations (log scale) generally exhibited stronger associations among these various measures than the PM(2.5) Mn concentrations. Comparisons of the particulate distributions between PTEAM (Riverside, CA) and the Indianapolis and Toronto studies were also made.  (+info)

Capsaicin-induced hyperalgesia and mu-opioid-induced antihyperalgesia in male and female Fischer 344 rats. (5/99)

The influence of sex in determining responses to opioid analgesics has been well established in rodents and monkeys in assays of short-lasting, phasic pain. The purpose of this investigation was to use a capsaicin model of tonic pain to evaluate sex differences in hyperalgesia and mu-opioid-induced antihyperalgesia in Fischer 344 (F344) rats. Capsaicin injected into the tail produced a dose-dependent thermal hyperalgesia in males and females, with the dose required to produce a comparable level of hyperalgesia being 3.0-fold higher in males than in females. These sex differences were modulated by gonadal hormones, inasmuch as gonadectomy increased the potency of capsaicin in males and decreased its potency in females. Morphine, buprenorphine, and dezocine administered by various routes [systemic (s.c.), local (in the tail), and central (i.c.v.)] generally produced marked antihyperalgesic effects in males and females. Although in most instances these opioids were equally potent and effective in males and females, selected doses of local and i.c.v. administered buprenorphine produced greater effects in females. When administered locally, the antihyperalgesic effects of morphine were mediated by peripheral opioid receptors in both males and females, since this effect was not reversed by i.c.v. naloxone methiodide. These data contrast with the finding that mu-opioids are more potent in male rodents in assays of phasic pain, thus suggesting that distinct mechanisms underlie male and female sensitivity to opioid antinociception in phasic and tonic pain models. These findings emphasize the need to test male and female rodents in tonic pain assays that may have greater relevance for human pain conditions.  (+info)

CONJUGATIONS WITH GLUTATHIONE. THE ENZYMIC CONJUGATION OF SOME CHLOROCYCLOHEXENES. (7/99)

1. alpha-3,4,5,6-Tetrachlorocyclohex-1-ene and gamma-2,3,4,5,6-pentachlorocyclohex-1-ene are conjugated with glutathione in vitro by a rat-liver enzyme that is probably glutathione S-aryltransferase. 2. Chlorocyclohexane and the alpha-, beta-, gamma- and delta-isomers of hexachlorocyclohexane were not substrates for rat-liver glutathione S-aryltransferase. 3. Glutathione-S-aryltransferase activity was present in tissue preparations of houseflies of insecticide-resistant and -susceptible strains. More activity was found in a dieldrin-resistant strain of houseflies fed on dieldrin than in either a dieldrin-resistant strain not fed on dieldrin or a control strain of dieldrin-susceptible houseflies. 4. Housefly soluble supernatant preparations converted S-(2-chloro-4-nitrophenyl)glutathione into the corresponding cysteine and mercapturic acid derivatives.  (+info)

THE METABOLISM OF METHYLCYCLOHEXANE. (8/99)

1. When [U-(14)C]methylcyclohexane is fed to rabbits (dose 2-2.5m-moles/kg. body wt.), 65% of the radioactivity is excreted in the urine as metabolites, 0.5% appears in the faeces and about 15% in the expired air, some 4-5% remaining in the body in about 60hr. after dosing. The 15% of the dose appearing in the expired air consists of unchanged methylcyclohexane (10%) and (14)CO(2) (5%). The low output of (14)CO(2) shows that reactions leading to complete oxidation of methylcyclohexane are of minor importance. 2. The main metabolite found in the urine was the glucuronide of trans-4-methylcyclohexanol which was isolated. Seven methylcyclohexanols were found in the urine as conjugated glucuronides. The amounts of these were determined by isotope dilution to be as follows: cis-2-, 0.6%; trans-2-, 1.2%; cis-3-, 11.5%; trans-3-, 10.5%; cis-4-, 2.4%; trans-4-methylcyclohexanol, 14.7%, cyclohexylmethanol, 0.3%. No 1-methylcyclohexanol was found. There was evidence also that a small amount (approx. 1%) of the hydrocarbon aromatized to benzoic acid, probably via cyclohexylmethanol and cyclohexane-carboxylic acid. 3. The pattern of hydroxylation and the various amounts of the isomers found suggest that the hydroxylation in vivo of methylcyclohexane is dependent on steric factors in the molecule, hydroxylation occurring to the greatest extent at the carbon atom furthest away from the methyl group.  (+info)

Standard lithographic procedures in addition to techniques like screen printing and electroplating are used to fabricate the sensor. A microbial strain of Trichosporon Cutaneum is immobilized over one pair of sensor electrodes while the other is used as a reference. Depending on the respiratory activities of the microbial strain in different samples, the BOD values of the samples can be measured in terms of difference between the output signals. The sensor layer is attached to an injection-molded passive microfluidic channel on the top. Advantages of the BOD microsensor include, but are not limited to, fast BOD measurement, disposability because of its low cost, chemically inert polymer substrate, flow-through sample injection scheme and integration of on-chip optics.

Communications DOI: 10.1002/anie.201006208 C H Functionalization Palladium-Catalyzed Dehydrogenative Cross-Couplings of Benzazoles with Azoles** Wei Han, Peter Mayer, and Armin R. Ofial* Biaryl compounds play an important role in nature and many functional materials.[1] Classical transition-metal-catalyzed methods for the synthesis of biaryls, such as Kumada, Negishi, Stille, Suzuki, and Hiyama-Denmark reactions, require functionalized arenes for the selective linkage of two arenes through a C C bond.[2] Recently, catalytic direct arylations have emerged which avoid the introduction of functional groups in at least one of the two coupling partners prior to cross-coupling by C H bond activation.[3] The development of direct selective intermolecular heteroarylations of heteroarenes appears particularly beneficial because prefunctionalizations of heteroarenes are often difficult. From the viewpoint of atom economy, twofold C H bond activation is the ideal strategy for interconnecting two ...
TY - JOUR. T1 - Efficient and phosphine-free bidentate N-heterocyclic carbene/ruthenium catalytic systems for the dehydrogenative amidation of alcohols and amines. AU - Wu, Xuan Jun.

N2 - The direct amide synthesis from alcohols and amines applying various transition metal catalysts has been demonstrated as an attractive and promising process. Among various catalytic systems, N-heterocyclic carbene (NHC)-based ruthenium (Ru) ones have been testified to be active for this atom-economic transformation. Although a variety of imidazole-based NHC/Ru catalytic systems were reported to be active for this reaction, the benzimidazole-based analogs exhibited higher catalytic performance in most cases. However, these catalytic systems, which comprise a monodentate NHC ligand and a Cl or phosphine ligand as the key components, require relatively ...

In order to remove the diesel particulate matter (PM) and nitrogen oxides (NOx) from diesel exhaust, the gas is passed through a corona discharge collector for PM and another corona discharge device for NOx oxidation. With the PM collector, PM is accumulated on the central electrode, after that, it is removed by incineration technique. NOx concentration is decreased by oxidation to HNO3. In this study, these corona discharge reactors were coupled for removal of PM and NOx in progression, and attempted to remove these emissions in a slipstream of 14 liters/min of an experimental diesel engine and an actual vehicle, respectively. In case of the experimental test engine, it is found that nearly 100% and 15% of the PM and NOx emissions were removed even at a low input power of 26W (1560 J/L specific energy deposition). In the vehicle tests 1) a PM removal rate of 60% is obtained at an input power of over 40W, 2) a NOx removal rate of 97% is obtained at an input power of over 100W ...

Propargyl alcohol is a useful synthon in synthetic organic chemistry. We found that the ruthenium(II) complex [Cp*RuCl(diene)] (Cp* = η5-C5Me5; diene = isoprene or 1,5-cyclooctadiene (cod)) catalyzes dimerization of 1,1-diphenylprop-2-yn-1-ol (1,1-diphenylpropargyl alcohol, 1a) at room temperature to afford an alkylidenebenzocyclobutenyl alcohol 2a quantitatively. Meanwhile, a stoichiometric reaction of the related hydrido complex [Cp*RuH(cod)] with 1a at 50 °C led to isolation of a ruthenocene derivative 4 bearing a cyclopentadienyl ring generated by dehydrogenative trimerization of 1a. Detailed structures of 2a and 4 were determined by X-ray crystallography. The reaction mechanisms for the formation of 2a and 4 were proposed.

The influence of temperature and hydrocarbon additives on NOx removal and CO production has been studied by numerical modelling and process experiments for a synthetic gas mixture consisting of N2 ,O 2 ,H 2O and CO2 in a pulsed corona reactor. The NO reduction of more than 99% was achieved at the energy cost of ∼14 eV per NO molecule in the presence of 550 ppm C3H6 additive at T = 393 K. The simulated results agree well with the experimental data measured in the NO and NOx removal and C2H4 and C3H6 decomposition. Within a limited framework of non-uniform modelling approach, the temperature effect on the streamer nature discharge has been taken into account. Main reaction paths for the C2H4 and C3H6 decomposition and leading reactions of NOx conversion, CO, CH2O, CH3CHO productions are presented. Calculated concentrations of some by-products are given. The effect of the C3H6 + O reaction on the NOx oxidation and C3H6 decomposition using several channels and their rate constants taken from the
Para 50] In a particularly preferred embodiment, the inventive plasma ignition plug used in a four-cycle engine provides the following dynamics. The fuel is atomized to 0.4 micrometer diameter droplets mixed with air in a fuel injector/carburetor jet diameter of 0.056 centimeters. The air and fuel is injected into the cylinder and a ratio of 1 4: 7- 1 mixture. Plasma propagation occurs at an ignition point of twenty-two degrees before top dead center with the plasma field propagated at fifty nanosecond rise time, two hundred nanosecond duration, and fifty nanosecond shutoff duration at 1 3.5 volts DC at forty-one thousand, six hundred sixty amps. At these values, the plasma field disassociates long chain hydrocarbon molecules to individual ions, evenly distributed at atomic scale proximity under pressure. The following ignition arc occurs fifty nanoseconds after the collapse of the plasma field with an injection ignition impulse at seventy-five thousand volts DC at 7.5 amps for two hundred ...
Piperidine is an organic compound with the molecular formula (CH2)5NH. This heterocyclic amine consists of a six-membered ring containing five methylene bridges (-CH2-) and one amine bridge (-NH-). It is a colorless liquid with an odor described as objectionable, and typical of amines. the name comes from the genus name Piper, which is the Latin word for pepper. Although piperidine is a common organic compound, it is best known as a representative structure element within many pharmaceuticals and alkaloids. Piperidine was first reported in 1850 by the Scottish chemist Thomas Anderson and again, independently, in 1852 by the French chemist Auguste Cahours, who named it. Both men obtained piperidine by reacting piperine with nitric acid. Industrially, piperidine is produced by the hydrogenation of pyridine, usually over a molybdenum disulfide catalyst: C5H5N + 3 H2 → C5H10NH Pyridine can also be reduced to piperidine via a modified Birch reduction using sodium in ethanol. Piperidine itself has ...

EXPERIMENT 1: REACTIONS OF ENOLATE IONS WITH CARBONYL GROUPS Aims In this experiment we used two techniques for the reactions of enolate ions with carbonyl groups. One technique used was Doebner reaction and the other technique used was Claisen-Schmidt reaction. Therefore the aim of this experiment is to synthesize trans p-methoxycinnamic acid and to synthesize dibenzalacetone via an aldol condensation reaction between acetone and benzaldehyde. The products would be recrystallized using ethanol, then characterized using melting point analysis. Introduction:. In this experiment we learnt on carbonyl compounds, enols and enolates. We also learnt two different techniques to test the reactions of enolate ions with carbonyl groups which are discussed below. I. Carbonyl Compounds, Enols and Enolates. Some of the most suitable reactions of carbonyl compounds contain carbon hydrogen bonds adjacent to the carbonyl group. Such reactions, which can be observed as the strength of much synthetic organic ...
Diesel fuels derived from different types of crude oil can exhibit different chemistry while still meeting market requirements and specifications. Oil sands derived fuels typically contain a larger proportion of cycloparaffinic compounds, which result from the cracking and hydrotreating of bitumens in the crude. In the current study, 17 refinery streams consisting of finished fuels and process streams were obtained from a refinery using 100% oil sands derived crude oil. All samples except one met the ULSD standard of 15 ppm sulfur. The samples were characterized for properties and chemistry and run in a simple premixed HCCI engine using intake heating for combustion phasing control. Results indicate that the streams could be equally well characterized by chemistry or properties, and some simple correlations are presented. Cetane number was found to relate mainly to mono-aromatic content and the cycloparaffins did not appear to possess any unique diesel related chemical effects ...

We describe a new class of heterogeneous catalysts called supported molten metal catalysis (SMMC), in which molten metal catalysts are dispersed as nanodroplets on the surface of porous supports, allowing much larger active surface area than is possible in conventional contacting techniques for catalytic metals that are molten under reaction conditions, thus greatly enhancing their activity and potential utility. Specific examples of different types of reactions are provided to demonstrate the broad applicability of the technique in designing active, selective, and stable new catalysts. It is shown that dispersing the molten metal on a support in the suggested manner can enhance the rate of a reaction by three to four orders of magnitude as a result of the concomitant increase in the active surface area. New reaction examples include {gamma}-Al{sub 2}O{sub 3} supported molten Te (melting point 450 C) and Ga (MP 30 C) catalysts for bifunctional methylcyclohexane dehydrogenation. These catalysts provide
Methylcyclohexane is a fully saturated strainless hydrocarbon and will not undergo a reaction with ozone, except at high concentrations (under such conditions it combusts). If you meant, 1-methylcyclohexene, the product is obtained by removing the double bond and attaching a double-bonded oxygen to each carbon atom. This gives 6-oxoheptanal. Then, after reducing you'll get 6-oxoheptanoic acid. This is your compound A. The last one specific carbonyl compound is 2-methylcyclohexanone ...

This paper starts by explaining how the vapour phase hydrogen peroxide rapid sporicidal process works and continues with a description of the present methods of cycle development. The paper continues with some suggestions as to how cycle development can be speeded up considerably and introduces enzyme indicators (EIs) as a recent development to add to chemical indicators (CIs) and possibly replace biological indicators (BIs). The paper offers practical solutions to both the problems mentioned above, based on long experience with the design, construction and validation of vapour phase hydrogen peroxide generators ...
Figure 31 indeed shows that fermionic atoms can pair and become molecular bosons, which can then condense into a molecular BEC. This is evident from the striking similarity of the interference patterns shown in Figures 26 and 31. Two overlapping degenerate Fermi gases would not create such macroscopic interference patterns because those wavefunctions have no intrinsic phase relationships, in contrast to the BEC wavefunctions. Molecular BECs, especially if the molecules are polar and can communicate with one anther through long-range forces, are of special interest as being quantum information storage devices, as individual molecules can potentially be addressed via their many internal degrees of freedom.. ...

Summary The field of C-H bond activation has evolved at an exponential pace in the last 15 years. What appeals most in those novel synthetic techniques is clear: they bypass the pre-activation steps usually required in traditional cross-coupling chemistry by directly metalating C-H bonds. Many C-H bond functionalizations today however, rely on poorly atom and step efficient oxidants, leading to significant and costly chemical waste, thereby seriously undermining the overall sustainability of those methods. As restrictions in sustainability regulations will further increase, and the cost of certain chemical commodities will rise, atom efficiency in organic synthesis remains a top priority for research. The aim of 2O2ACTIVATION is to develop novel technologies utilizing O2 as sole terminal oxidant in order to allow useful, extremely sustainable, thermodynamically challenging, dehydrogenative C-N and C-O bond forming coupling reactions. However, the moderate reactivity of O2 towards many catalysts ...

Cecil replies: Maybe its just me, but when I hear somebody go on about revolutionary discoveries, negative high energy, or anything to do with ions (which are what a corona discharge device produces), I make sure Ive got a firm grip on my wallet. Still, one never likes to dismiss things out of hand. We even tested laundry balls, remember? So I sent Jane to rummage through the archives. The assembled research presents the usual inconclusive muddle. Some observations: Air ionization is to todays scientists what magnetism was to medical types in the 19th century. In other words, a possible cure for just about anything. A computer search turned up nearly 400 scientific articles on air ionization, claiming that negative ions do everything from reduce asthma symptoms to improve your mood and enhance childrens learning ability. Yet the methodology of these studies is sometimes suspect. For example, a couple papers claim that daily sessions with a high-output negative ionizer will alleviate seasonal ...
CL color and intensity are dependent on the characteristics of the sample and on the working conditions of the electron gun. Here, acceleration voltage and beam current of the electron beam are of major importance. Today, two types of CL microscopes are in use. One is working with a "cold cathode" generating an electron beam by a corona discharge tube, the other one produces a beam using a "hot cathode". Cold-cathode CL microscopes are the simplest and most economic type. Unlike other electron bombardment techniques like electron microscopy, cold cathodoluminecence microscopy provides positive ions along with the electrons which neutralize surface charge buildup and eliminate the need for conductive coatings to be applied to the specimens. The "hot cathode" type generates an electron beam by an electron gun with tungsten filament. The advantage of a hot cathode is the precisely controllable high beam intensity allowing to stimulate the emission of light even on weakly luminescing materials (e.g. ...

Students learn the molecular structures of organic compounds (alkanes, cycloalkanes, alkenes, alkynes, alcohols, ethers, aldehydes, and ketones) and their relationship with their macroscopic physical and chemical properties, and various possible paths of organic synthesis based on the identification of functional groups. The course will give emphasis on: a. the relationship between chemical structures and physical/chemical properties of the materials; and b. the comprehension on the reaction mechanism based on the molecule stability theory. The teaching process will be descriptive and analytical based on general principles of molecule stability, functional group characters, etc.
Herein, an approach for simulating phase diagrams of binary mixtures is presented, where a bulk liquid and its corresponding vapour phase are simulated by means of molecular dynamics using explicit polarisation. Time-averaged density profiles for the pure compounds and mixtures at different mole fractions provide information about the spatial distribution in the bulk liquid and the amount of evaporated species in the adjacent vapour phase. The activities in the liquid phase are calculated from the mean vapour phase densities at a given composition, providing a good qualitative agreement compared to experimental data and the precision of the method follows a previously developed Poisson model of evaporation. With the Redlich-Kister approach for the activities in a binary mixture, the directly obtained activities are fitted providing corrected activity coefficients of the two species. This method is applied to ethanol water mixtures at different mole fractions. The obtained structural data are in good

Electrostatic precipitator (ESP) systems and methods are provided. A system includes at least one corona discharge electrode and at least one collector (and likely, at least a pair of collector electrodes) that extend downstream from the corona discharge electrode. An insulated driver electrode is located adjacent the collector electrode, and where there is at least a pair of collector electrodes, between each pair of collector electrodes. A high voltage source provides a voltage potential to the at least one of the corona discharge electrode and the collector electrode(s), to thereby provide a potential different therebetween. The insulated driver electrode(s) may or may not be at a same voltage potential as the corona discharge electrode, but should be at a different voltage potential than the collector electrode(s).
A microfluidic platform for the rapid determination of distribution coefficients by gravity assisted droplet-based liquid-liquid extraction, C. E. Poulsen, R. C. R. Wootton, A. Wolff, A. J. deMello & K. S. Elvira, Analytical Chemistry, 2015, 87, 6265. The aim of this research was to use microfluidic technologies to provide an original improvement to a method that has not been updated in decades, namely the determination of distribution coefficients. The platform provides clear advantages to the traditional shake-flask method (it is 48 times faster, uses 99% less reagents, has very low user sensitivity and higher reproducibility), whilst being as simple as possible: the platform makes use of picolitre-sized droplets to take advantage of the large surface-area-to-volume ratios, but uses a separation chamber that falls in the milli-fluidic regime to enable the use of gravity for phase separation. To allow this platform to be used in commercial settings, it was fabricated using cyclic olefin ...

Angewandte Chemie Amine Synthesis Asymmetric Synthesis of Diarylmethyl Amines by Rhodium-Catalyzed Asymmetric Addition of Aryl Titanium Reagents to Imines** Tamio Hayashi,* Masahiro Kawai, and Norihito Tokunaga Asymmetric synthesis of diarylmethyl amines has attracted growing attention owing to their importance in biological activity.[1] Among several methods for performing the asymmetric synthesis,[2, 3] catalytic asymmetric addition of aryl metal reagents to imine derivatives seems to be most promising, provided that both high enantioselectivity and high catalytic activity are realized.[4] After our publication on the rhodium-catalyzed asymmetric addition of aryl stannanes to N-sulfonylimines,[5] two reports appeared on catalytic asymmetric arylation: 1) Br%se, Bolm, and co-workers described the addition of a phenylzinc reagent to masked Nformylimines in the presence of a chiral ketimine catalyst,[6] and 2) Tomioka illustrated the rhodium-catalyzed addition of aryl boroxines to N-tosylimines ...

The olefin metathesis reaction has become a widely used method for the construction of new carbon-carbon double bonds. The development of well-defined, ruthenium-based catalysts with high air- and moisture-stability and functional group tolerance has allowed synthetic chemists to exploit this reaction in many areas. The main goal of this thesis was to better understand the impact of changes in catalyst and monomer structure on the olefin metathesis reaction. The introduction of chelating alkylidene ligands to olefin metathesis catalysts has resulted in systems with high activity and stability that, for the most part, are active at or below room temperature. However, for some applications, catalysts that react only at higher temperatures are desirable. Chapter 2 describes the synthesis of latent olefin metathesis catalysts with chelating alkylidenes with a range of donor ligands: including phosphines, pyridines, imines, amines, and thioethers. The nature of the donor ligand was found to have a ...
