Atmospheric Pressure Chemical Ionisation (APCI) is an ionisation method used in mass spectrometry utilising gas-phase ion-molecule reactions at atmospheric pressure. Ionisation is effected using a corona discharge. This is a method of soft ionisation, where little fragmentation occurs in the source of the mass spectrometer.. Mass Spec uses APCI for trace analysis - primarily for drugs detection, but can be used for a wide range of other substances.. ...

An RF plasma deposition apparatus for depositing a film of material on substrates positioned in a vertical plane and electrically floating within the glow discharge. For deposition of silicon nitride films, the apparatus is adapted to introduce silane gas in a substantially uniform and laminar flow into a coating cavity containing substrates, a ground screen electrode, and a hot RF electrode, within which a glow discharge is ignited. Elemental nitrogen may be delivered to the coating cavity after being dissociated in a local, separate RF plasma called an atomizer cavity. During coating, elemental nitrogen combines with elemental silicon and deposits silicon nitride upon the substrate surface.

Part I - Fluorinated Compounds A method has been developed for the extraction, concentration, and determination of two unique fluorinated compounds from the sediments of Lake Ontario. These compounds originated from a common industrial landfill, and have been carried to Lake Ontario by the Niagara River. Sediment samples from the Mississauga basin of Lake Ontario have been evaluated for these compounds and a depositional trend was established. The sediments were extracted by accelerated solvent extraction (ASE) and then underwent clean-up, fractionation, solvent exchange, and were concentrated by reduction under nitrogen gas. The concentrated extracts were analyzed by gas chromatography - electron capture negative ionization - mass spectrometry. The depositional profile determined here is reflective of the operation of the landfill and shows that these compounds are still found at concentrations well above background levels. These increased levels have been attributed to physical disturbances of ...

Electric field distributions and discharge properties of rod-rod contact electrodes were studied under the condition of DBD for the steady generation of atmospheric pressure glow discharge plasma (APGD) in air. We found that under the effect of the initial electrons generated in a nanometer-scale gap, the rod-rod cross-contact electrodes yielded APGD plasma in air. Regarding the rod-rod cross-contact electrodes, increasing the working voltage expanded the strong electric field area of the gas gap so that both discharge area and discharge power increased, and the increase in the number of contact points kept the initial discharge voltage unchanged and caused an increase in the plasma discharge area and discharge power. A mesh-like structure of cross-contact electrodes was designed and used to generate more APGD plasma, suggesting high applicability. ...

Atmospheric pressure chemical ionization (APCI) is an ionization method used in mass spectrometry which utilizes gas-phase ion-molecule reactions at atmospheric pressure (105 Pa), commonly coupled with high-performance liquid chromatography (HPLC). APCI is a soft ionization method similar to chemical ionization where primary ions are produced on a solvent spray. The main usage of APCI is for polar and relatively less polar thermally stable compounds with molecular weight less than 1500 Da. The application of APCI with HPLC has gained a large popularity in trace analysis detection such as steroids, pesticides and also in pharmacology for drug metabolites. A typical APCI usually consists of three main parts: a nebulizer probe which can be heated to 350-500oC, an ionization region with a corona discharge needle, and an ion-transfer region under intermediate pressure. The analyte in solution is introduced from a direct inlet probe or a liquid chromatography (LC) eluate into a pneumatic nebulizer ...

In 2004, the National Tree Seed Centre started collecting ash seed for genetic conservation.. Natural ash populations have adapted to their environments. Preserving germplasm from a significant number of these populations will facilitate the reintroduction of ash species once adequate environmental control measures for EAB are developed or trees resistant to the insect are bred and introduced. The easiest way to assemble breeding material is to collect seed from native stands. The seed will not transmit EAB to non-infested areas.. When properly handled and stored, ash seed will remain alive for many decades. Seed can be easily distributed to scientists and growers to produce seedlings for EAB research, breeding, genetics projects, other scientific study and future reintroduction efforts.. We encourage organizations as well as the general public to assist us in this effort by locating ash stands and populations and collecting seed to send to us.. To ensure the proper identification, collection ...

The Effect of Radio Frequency Discharge Plasma on Surface Properties and Biocompatibility of Polycaprolactone Matrices written by TPU researchers together with their colleagues from Kemerovo Research Institute for Complex Issues of Cardiovascular Diseases (NII KPSSZ) studies the effect of surface modification of bioresorbable polymer material (polycaprolactone, PCL) with abnormal glow discharge, initiated during radio-frequency magnetron sputtering of a hydroxyapatite target.. TPU scientists analyzed plasma exposure of PCL surface on bone marrow multipotent mesenchymal stromal cells behavior (BM MSCs). It was identified that modification of polymer surface with abnormal glow discharge stimulated adhesion and subsequent proliferation of BM MSCs. This type of plasma modification did not affect cell viability (apoptosis, necrosis). Thus, the surface modification with abnormal glow discharge, initiated during radio-frequency magnetron sputtering of a hydroxyapatite target, appeared to be a promising ...

Recently, hard X-ray high kinetic energy photoelectron spectroscopy has lead to a break-through due to its non destructive way of investigating the bulk electronic properties of materials. However, due to the relatively new development of this technique there is a lack of information concerning the photoionization cross sections at high energies. Whenever compound materials are investigated or when estimating signal levels and the feasibility of an electron spectroscopy experiment the knowledge of cross sections is essential. In the present work the experimentally determined relative sub-shell photoionization cross sections of shallow levels of nickel metal in the energy range of 2-9 keV will be shown. The data are compared with calculated sub-shell photoionization cross sections.. ...

TY - JOUR. T1 - Acid-base equilibria in aqueous solutions of 2-aminopurine radical cations generated by two-photon photoionization. AU - Shafirovich, Vladimir. AU - Dourandin, Alexander. AU - Luneva, Natalia P.. AU - Geacintov, Nicholas E.. PY - 2000/2. Y1 - 2000/2. N2 - The acid-base equilibria of the nucleic acid analogue 2-aminopurine (2AP) and 2-aminopurine riboside (2-APr) radicals generated by two-photon photoionization of the 2AP residues with intense 308 nm XeCl excimer laser pulses (fwhm = 12 ns, ca. 70 mJ cm-2 pulse-1) have been investigated using transient absorption spectroscopy techniques. It is of interest to investigate the properties of these radicals as a function of pH because of their abilities to undergo proton-coupled electron transfer reactions with other nucleic acid bases. Pronounced differences in the 2AP and 2APr radical absorption bands are observed in the 330-550 nm spectral region within the pH range of 1 to 12. These differences are attributed to the deprotonation ...

We report TOFMS investigations on the effects of hydrogen added to a dc GD argon plasma, in detail over the most likely concentration range occurring in analytical work (0-0.10% v/v), together with an overview to 0.8% v/v; typical GD-OES discharge conditions were used. Many previous studies on the effects of hydrogen in analytical GD-MS used much higher hydrogen concentrations. In this paper, we report for the first time the hydrogen effect on relative ion signal intensities of matrices, plasma and added gas, for very low but analytically important hydrogen concentrations. We investigate the behavior of doubly charged argon ions (Ar++), dimer ions (Cu2+, Fe2+, Ti2+, Ar2+) and polyatomic ions (ArH+, CuH+, FeH+, TiH+), which can play important roles in plasma processes. We discuss the probable discharge mechanisms in order to gain a greater understanding of the fundamental processes involved in the ionization of the species observed in this study and their likely effects on analytical results. ...

The results are presented of an intensive study of a railway tunnel environment under conditions of fully dieselized train traffic. Atmospheric sampling tests were conducted around the clock on an B-HR working shift basis for three days. More than 2000 observations were made to determine the fluctuations and range of occurrence of contaminant concentration under a variety of traffic conditions. There were no abnormal health effects on participants during exposure in the tunnel atmosphere, with the exception of minor cases of eye and throat irritation. However, nitrogen dioxide, aldehydes, smoke, and particulate matter attained high levels during periods of peak train activity. Therefore, installation of appropriate forced-draft ventilation is recommended for the tunnel before full dieselization is introduced to replace electrical operation of trains.. ...

Press release from Leeds University Study: New weapon to fight hospital infections - January 2, 2003 A potential new weapon in the fight against hospital acquired infections has been discovered by researchers at the University of Leeds. The scientists studied the effect of negative air ionizers on infections caused by acinetobacter; a pathogen responsible for increasing numbers of sometimes fatal infections amongst hospital patients. Ionizers were placed in the intensive care unit at St Jamess University Hospital, which, like similar wards across the UK, has had recurrent problems with infections caused by acinetobacter. For the first six months the researchers, from the aerobiological research group in the Universitys school of civil engineering, monitored the normal situation in the unit, taking samples from surfaces, patients and from the air to monitor bacteria levels, and logging the number of patient infections. During the second half of the year-long trial, the ionizers were switched ...

Theoretical analysis of the mechanism of action of chemical aerial disinfectants reveals that the rapid killing action which is obtained cannot be accounted for by a collision process between germicidal aerosol particles and the air-borne bacteria. However, a mechanism involving condensation of germicide molecules in the vapor state on to the bacteria-containing droplets results in a theoretical velocity of the correct order of magnitude.. Experimental tests of this theory show that pure germicide vapors free of aerosol droplets are almost instantly lethal to air-borne bacteria. Conversely, pure germicidal aerosols in the absence of vapor, had no effect on air-borne bacteria within 20 minutes or more. Therefore, it may be concluded on both theoretical and experimental grounds that rapid air sterilization requires the existence of the germicide in the vapor state.. ...

Hi mum2000,. I dont have much experience of bosniak cysts either but my surgery for cancer was delayed for a few weeks as they were concerned about my potentially having sleep apnoea because of my weight. I was tested and found to have the condition and then had to successfully learn how to sleep using a variable positive air pressure machine that blows air into my lungs if I stop breathing when I sleep. I had to take the machine with me when I went for my surgery and was advised that rather than being taken to a surgical recovery ward after my operation I would be going to intensive care where I could be more closely monitored. I understand that the rationale behind this was that if I had breathing difficulties during the operation I could die very quickly whilst not operating on the kidney cancer it would take a number of years for it to become terminal.. As the cyst is classed as small and there are some concerns about your lungs it is likely to be similar concerns that are at work here. ...

The HR Del nova remnant was observed with the IFU-GMOS at Gemini North. The spatially resolved spectral data cube was used in the kinematic, morphological, and abundance analysis of the ejecta. The line maps show a very clumpy shell with two main symmetric structures. The first one is the outer part of the shell seen in Hα, which forms two rings projected in the sky plane. These ring structures correspond to a closed hourglass shape, first proposed by Harman & OBrien. The equatorial emission enhancement is caused by the superimposed hourglass structures in the line of sight. The second structure seen only in the [O III] and [N II] maps is located along the polar directions inside the hourglass structure. Abundance gradients between the polar caps and equatorial region were not found. However, the outer part of the shell seems to be less abundant in oxygen and nitrogen than the inner regions. Detailed 2.5-dimensional photoionization modeling of the three-dimensional shell was performed using the

The development of new technologies that reduce engine size and improve performance, combined with the introduction of hybrid and electric vehicles, make tire noise critically important for the new generation of automobiles. Tire noise transmission into the passenger compartment can be classified as either air-borne or structure-borne sound. Both of these mechanisms are very complex to predict because tires are highly non-linear, subject to large static, dynamic and centrifugal loads; they suffer from impact, stick and slip forces; and the pumping of air in the tire grooves is complicated. Customers today demand more sophistication of products in terms of interior noise; thus, sound quality metrics have earned an important role during the design phase allowing human perception of noise to be predicted and improved with reduced cost in a way that addresses consumer preferences. Of the various metrics, loudness has been shown to be the most important metric due to consideration of masking effects ...

Matrix-assisted laser desorption/ionization (MALDI) is a soft ionization technique that is widely applied in the characterization of large biomolecules using various mass spectrometry (MS) analyzers, specifically, time-of-flight (TOF) analyzers. The MALDI process involves the deposition of an analyte solution onto a metal substrate before the addition of a matrix. The matrix/analyte dry spot is exposed to a UV laser, and the laser energy that is absorbed by the matrix/analyte is converted into heat energy that initiates charge transfer, which results in the desorption of the matrix and analyte molecules in ionized form. The positive ions are then accelerated through a vacuum into MS analyses.

Matrix-assisted laser desorption/ionization (MALDI) is a soft ionization technique used in mass spectrometry, allowing the analysis of biomolecules (biopolymers such as DNA, proteins, peptides and sugars) and large organic molecules (such as polymers, dendrimers and other macromolecules), which tend to be fragile and fragment when ionized by more conventional ionization methods. It is similar in character to electrospray ionization (ESI) in that both techniques are relatively soft ways of obtaining ions of large molecules in the gas phase, though MALDI produces far fewer multiply charged ions.. MALDI methodology is a three-step process. First, the sample is mixed with a suitable matrix material and applied to a metal plate. Second, a pulsed laser irradiates the sample, triggering ablation and desorption of the sample and matrix material. Finally, the analyte molecules are ionized by being protonated or deprotonated in the hot plume of ablated gases, and can then be accelerated into whichever ...

Mass spectrometry (MS) has advanced to analyze ever-larger biomolecules with the invention of soft ionization techniques like electrospray ionization (ESI). Although ESI has provided a method of generating ions of high mass, mass spectrometers generally suffer both lower sensitivity and lower resolution as the mass-to-charge ratio of an ion increases. To extend the mass range of ionized macromolecules beyond the limits of MS, macroion mobility spectrometry utilizes ion mobility sizing to characterize charge-reduced ESI-generated macroions from ,5 kDa to beyond megadalton masses. One prominent application of macroion mobility spectrometry, highlighted here, is the high sensitivity analysis of intact proteins, antibodies, and conjugates in which molecular masses range from antibody light-chain fragments to high mass immunoglobulin multimers. ...

The technical advances in mass spectrometry, particularly the development of (ultra)-high-resolution/mass accuracy measurement capabilities in combination with refinement of soft ionization techniques, have increased the application and success of lipidomics to answer biological questions in relation to lipid metabolism. Together with other omics technologies, lipidomics has become an important tool to practice systems biology as lipids comprise a very significant part of the metabolome and play pleiotropic roles in cellular functions. As an increasing number of disorders are linked to lipid metabolism, lipidomics is used to search for biomarkers, understand disease mechanism and follow the efficacy of therapeutic options. This review provides a first introduction to the major methodological strategies currently used for mass spectrometry-based lipidomics and associated data pre-processing and analysis ...

Glow Inc.s brand of glow in the dark paint is a custom formula designed to maximize brightness in a durable all-purpose paint. The engineers included a suspension system that supports the relative dense glow in the dark particles. It contains no fillers or impurities such as ultraviolet filters, which interfere with glow pigment. As a solvent-based acrylic, it is extremely durable for indoor and outdoor use and has strong adhesion to almost all surfaces. Drying time is between 10-15 minutes, but should be allowed to cure overnight.. Our paints are created by mixing the raw pigment (glow powder) with the custom designed paint in a ratio of 2 lbs. of glow in the dark pigment to 1 gallon of paint. This high ratio along with the high clarity medium results in the brightest glow in the dark paint sold on the planet.. This paint CANNOT be shipped outside of the U.S. Please note that domestic shipping charges have been added to this products price.. ...

Positive pressure isolation is used to protect patients with weakened immune systems from airborne contaminants in the hospital environment. These immunocompromised patients include cancer, burn, leukemia and AIDS patients and those who have recently gone through bone marrow or organ transplantation. Building positive pressure isolation rooms with Genano is easy and highly cost-efficient. Only minor piping work is needed to connect the Genano air purifier to central ventilation. All of the supply air enters the room through the unit. Genano Technology effectively collects airborne microbes and eliminates them inside the unit. The unit can simultaneously be used to create positive air pressure inside the room. This prevents non-hygienic air from other premises from entering the room. In addition to supply air, staff, visitors and equipment can carry pathogens and other contaminants into the room. Therefore a second unit is utilized to constantly circulate and purify the air from any process and human

There were some interesting things learned in the process of making the ghostly green lamp. The first part of the build log is all about post-processing the lantern model, which was 3D printed at a chunky 0.48 mm layer height, but the rest is about getting the ghostly green glow to come out the way it did. [cyborgworkshop] used both glow in the dark paint and glow in the dark powder to really make the object pop, but the process involved some trial and error. Originally he mixed the glow powder into some clear varnish, and despite the mixture turning pink for some mysterious reason, a small sample spot appeared to turn out fine. However, after applying to the lantern and waiting, the varnish remained goopy and the glow powder settled out of the mixture. He ended up having to remove it as best he could and tried a heavy application of the glow paint instead. This ended up being a real blessing in disguise, because the combination resulted in a gritty stone-like texture that glowed brightly! As ...

Greg Smoak, director of the American West Center at the University of Utah, talked about Utahs Great Salt Lake, the Native Americans who used the land, and the European explorers who first saw the Lake. He visited sites that attracted vacationers and tourists during the late 19th and early 20th century, and talked about some industries that have grown in the area due to the resources that the lake has to offer. C-SPANs Local Content Vehicles (LCVs) made a stop in their 2014 LCV Cities Tour in Salt Lake City, Utah, from May 4-8 to feature the history and literary life of the community. Working with the Comcast Cable local affiliate, they visited literary and historic sites where local historians, authors, and civic leaders were interviewed. The history segments air on American History TV (AHTV) on C-SPAN3 and the literary events/non-fiction author segments air on BookTV on C-SPAN2.

The primary acting factor in Halotherapy is the inhalation of Dry Salt Aerosol. A generator, which by means of mechanical actions, crushes pharmaceutical grade salt into micron-sized particles. This creates a dry salt aerosol between the size of 1 to 10 micrometers (smaller than particles contained in cigarette smoke). Particles bigger than 10 micrometers are caught in the nose and the throat, whereas, particles the size of 1 micrometer can penetrate deep into the lungs and even into the blood stream. These small particles of salt are negatively ionized and bear a very high kinetic energy. This way, it is guaranteed that it gets into the deepest and smallest parts of the lung. Negative ionization of salt increases the efficiency of healing.Dry Salt Aerosol cleanses human airways, like a toothbrush cleans teeth. It alleviates bronchial inflammation, removes pathogen agents (airborne pollen) and speeds up mucociliary transport ...

Performance & security by Cloudflare, Please complete the security check to access. It is transferred to the surface electrostatically with a spray gun that is both the conveyance for the material and the source of the static electricity. Powder coating is a type of coating that is applied as a free-flowing, dry powder.Unlike conventional liquid paint which is delivered via an evaporating solvent, powder coating is typically applied electrostatically and then cured under heat or with ultraviolet light. T Party apparently left an acetone soaked rag in his boat for five days and the gel coat was attacked. Id personally bring it back and explain you messed it up. I just used straight acetone on my car and it worked perfectly, with no damage to my car. IVD takes advantage of glow discharge cleaning to achieve excellent adhesion of coating to substrate. A second cured coat added about an additional .002 inch in diameter. MEK and acetone only work if your powder coater did not bake the parts for long ...

The ability to etch deep trenches in silicon while controlling not only the profile of etched features but also the etching rate, uniformity and selectivity enable us to expand the number and scope of MEMS devices. In fact, the increase of MEMS applications in different and varied fields requiring deep silicon etching or high aspect ratio structures (HARS) has even been extended to include microturbomachinery which was recently introduced as a feasible source of power generation. Many projects also place additional demands on surface morphology. Thus, the scalloping observed on vertical walls during time multiplexed deep etching (TMDE), the roughness of horizontal surfaces exposed to the glow discharge and the radius at the bottom of etched features are also relevant. Therefore, it is important to understand not only the plasma processes involved but also the dependence of response variables on operating conditions. For this purpose we have designed, performed and analyzed sets of experiments ...

Summertime comes with a lot of perks, but the most exciting of them is the summer glow. Irrespective of who you are, your natural complexion or your location, the probability is that you look glowing and sun-kissed, and you want to maintain this glow during fall, through the winter and till the Memorial Day in the coming year. Luckily, by sticking to the perfect skin treatment regimen, it is achievable.. 1. Use Sunscreen. The fact that the warm weather is gone does not mean the suns UV rays have. If you want to maintain that glow all year round, apply SPF daily. Sunscreen goes beyond protecting your skin; it also gives you a natural look.. 2. Utilize a Tanning Lotion. Actualizing a sun-kissed glow throughout the year demands deterrence from your summer skin treatment regimen in all respects. Employ a tanning lotion instead of hitting the beach to add color to your look. Tanning lotion is active, and they are quite safer to utilize compared to visiting a tanning salon.. 3.
