Öfele and Wanzlick first pioneered the metalation of imidazol-2-ylidenes, better known as N-heterocyclic carbenes (NHCs), from imidazolium salts in 1968.1,2 Lappert and co-workers followed this work with the investigation of N-heterocyclic carbene complexes synthesized from electron-rich olefins.3,4 However, it was not until the isolation of the first free carbene by Arduengo, in 1991, that significant interest was given to the area.5 Since then the complexation chemistry of these new ligands has become a major area of research.6-10 This new class of ligand has shown to equal, if not exceed, phosphines in their ability to bind to a variety of metals. Complexes of N-heterocyclic carbenes with virtually every transition metal and many main group elements have been reported.1-10 N-Heterocyclic carbenes bind to both hard and soft metals making it a very versatile ligand system. NHCs bond to metals primarily through σ donation of the carbene lone pair to the metal. The bonding of the carbene was believed

Sediments from four inshore industrial sites and a reference site in the Great Lakes were extracted with solvents and characterized chemically for polycyclic aromatic compounds (PACs). An aqueous phase and a crude organic extract were obtained. The crude organic extract was further resolved into fractions A-2 (polycyclic aromatic hydrocarbons) and A-3 (nitrogen-containing polycyclic aromatic compounds), which were analyzed for PACs by gas chromatography and gas chromatography-mass spectrometry. The extracts and fractions were tested for mutagenicity in three assays: Ames, rat hepatocyte unscheduled DNA synthesis, and Chinese hamster ovary hypoxanthine-guanine phosphoribosyl transferase (CHO/HGPRT). Sediments from the industrial sites contained 27 to 363 μg/g total PACs; the reference site, less than 1 μg/g. Qualitative differences in the residue profiles among the sites were attributable to the probable sources of the PACs (petroleum versus combustion). Only one industrial site yielded measurable (0.1
Using inorganic fullerene-like (IF) nanoparticles and inorganic nanotubes (INT) in organic-inorganic hybrid composite, materials provide the potential for improving thermal, mechanical, and tribological properties of conventional composites. The processing of such high-performance hybrid thermoplastic polymer nanocomposites is achieved via melt-blending without the aid of any modifier or compatibilizing agent. The incorporation of small quantities (0.1-4 wt.%) of IF/INTs (tungsten disulfide, IF-WS2 or molybdenum disulfide, MoS2) generates notable performance enhancements through reinforcement effects and excellent lubricating ability in comparison with promising carbon nanotubes or other inorganic nanoscale fillers. It was shown that these IF/INT nanocomposites can provide an effective balance between performance, cost effectiveness, and processability, which is of significant importance for extending the practical applications of diverse hierarchical thermoplastic-based composites.
Organic-inorganic hybrid composites have attracted considerable attention because of their distinctive physical and chemical properties. Specifically, the multiwalled carbon nanotube (MWNT)-polymer composites among them has expected when uniform dispersion of the MWNTs in the polymer matrix is achieved without their aggregations. Consequently, a strong MWNT/polymer matrix interaction is needed. Recently, the MWNT was successfully functionalized with aminopropylisooctyl-polyhedral oligosilsesquioxane (POSS) by reacting the amine groups in POSS with the MWNTs functionalized with -COCl groups, and it was reported that a more uniform and fine dispersion of MWNTs was achieved throughout the polymer matrix after functionalization due to the strong interfacial adhesion between the MWNTs and the polymer matrix. There have been less studied on unique micristructure and properties of electrospun nanofibers incorporating POSS hybrids. In this work, we attempt to modify the MWNTs with POSS for well-dispersion of
Adsorption kinetics of organic-inorganic (hybrid) Al(OH)3-polyacrylamide (Al-PAM) with different molecular weights (for organic characteristics) and contents of aluminum hydroxide nanoparticles (for inorganic characteristics) on kaolinite basal planes was studied using a versatile quartz crystal microbalance with dissipation (QCM-D). The flocculation dynamics of kaolinite by Al-PAMs was assessed by measuring the initial settling rate of flocculated kaolinite particles and the turbidity of the supernatant after settling of flocculated solids. The areal mass (mg/m2) of Al-PAMs adsorbed on tetrahedral silica and octahedral alumina basal planes of kaolinite increased with increasing molecular weight of the polymer. Increasing the content of Aluminum hydroxide nanoparticle in Al-PAM has resulted in an increase of the amount of the polymer adsorbed on silica basal planes while opposite trend was found on alumina basal planes. Results obtained from the adsorption kinetics study of Al-PAM6R (Mw = 2.2 million

Edible films based on chitosan were prepared, with and without basil or thyme essential oils, with the aim of assessing their protective ability against lipid oxidation and their antimicrobial activity. Chitosan films had good oxygen-barrier properties, which were worsened by essential oil addition, especially when the film equilibrium moisture content increased. Due to the oxygen-barrier effect, all the films effectively protected pork fat from oxidation, in comparison to unprotected samples. In spite of the worsening of the oxygen-barrier properties, the films with essential oils were more effective than those of pure chitosan, which points to the chemical action of specific antioxidant compounds of the oils. Films were effective to control microbial growth in minced pork meat, although the incorporation of essential oils did not improve their antimicrobial activity. Throughout the storage, the films led to colour changes in minced pork meat associated with the conversion of myoglobin into ...

Stormwater management BMPs are control measures taken to mitigate changes to both quantity and quality of urban runoff caused through changes to land use. Generally BMPs focus on water quality problems caused by increased impervious surfaces from land development.[11] BMPs are designed to reduce stormwater volume, peak flows, and/or nonpoint source pollution through evapotranspiration, infiltration, detention, and filtration or biological and chemical actions.[12] BMPs also can improve receiving-water quality by extending the duration of outflows in comparison to inflow duration (known as hydrograph extension), which dilutes the stormwater discharged into a larger volume of upstream flow.[13] Stormwater BMPs can be classified as structural (i.e., devices installed or constructed on a site such as silt fences, rock filter dams, fiber rolls (also called erosion control logs or excelsior wattles), sediment traps and numerous other proprietary products) or non-structural (procedures, such as ...

DFT and Quantum Chemical Studies for Heterocyclic Compounds, 978-3-659-21601-5, 9783659216015, 3659216011, Inorganic chemistry , The study of corrosion processes and their inhibition by organic inhibitors is a very active field of research. The presence of nitrogen, oxygen, phosphorous and sulphur in the organic molecules has a major effect on the inhibition efficiency and consequently on the phenomenon of adsorption on some metals surface. A great number of heterocyclic compounds were found to be excellent inhibitors of copper and steel corrosion. The inhibition effect mainly depends on some physicochemical and electronic properties of the organic inhibitor which relate to its functional groups, steric effects, electronic density of donor atoms, and orbital character of donating electrons. DFT Quantum chemical methods have already proven to be very useful in determining the molecular structure as well as elucidating the electronic structure and reactivity. Thus, it has become a common practice to

Before going ahead and understanding proteins - the biomolecules, it is important to first understand amino acids. Amino acids are the organic compounds mainly bonded to a hydrogen atom, a carboxyl group (COO-) and an amine group (NH2) along with a side chain (represented as R in the diagram) which is specific to every amino acid. There are about 500 amino acids known. The two broad groups into which these amino acids can be distributed are: proteinogenic amino acids and non-proteinogenic amino acids. The word proteinogenic means protein building. Interesting to note is that of these 500 amino acids, only 23 naturally occurring amino acids come under proteinogenic amino acids i.e.; these amino acids are precursors to proteins. Of these 23, 20 proteinogenic amino acids are encoded by codons (triplet) in genetic code and are called standard amino acids. The other three which are non-standard amino acids are pyrrolysine, selenocysteine and N-formylmethionine. The pyrrolysine is found in ...

In the past, people used herbs as a form of treatment for illness. Nowadays, the mainstream belief is that they are not as effective and not worth taking. For each health issue people use pharmaceutical drugs. This is because effectiveness of each herb and their use has not been studied deeply to determine how effective it can be. On the other hand, pharmaceutical drugs are attempted to mimic a compound that occurs naturally in nature (herbs). They can also bring the risk of side effects.. According to stats released by the American Association of Poison Control Centers, no deaths have been reported due to the use and consumption of herbs. However, pharmaceutical drugs and physician prescribed medications kill approximately one million Americans each year. It is important to note that herbal medicines can be lethal in extreme doses it appears their safety is much greater than that of pharmaceutical drugs.. Pharmaceutical drugs can have side effects on human health. For example antibiotics in ...

In WT mice, endothelium-dependent relaxations of small mesenteric arteries were mainly mediated by EDHF, whereas those of the aorta were mediated by NO, a finding that is consistent with our previous studies (2, 4, 14). Interestingly, EDHF-mediated relaxations were progressively reduced in accordance with the number of disrupted NOS genes in mesenteric arteries and were absent in n/i/eNOS−/− mice, indicating that EDHF-mediated relaxations are totally mediated by the endothelial NOSs system in mouse mesenteric arteries.. In this study, after the classical definition of EDHF (1-3), we evaluated EDHF-mediated responses in mouse mesenteric arteries in the presence of indomethacin and l-NNA. It is known that eNOS generates superoxide anions under normal conditions from reductase domain and only when uncoupled (e.g., BH4 and/or l-arginine depletion) from the oxidase domain, and that l-arginine analogues only inhibit the latter process (40). Indeed, we were able to demonstrate that endothelial ...
