ethylbenzene/dental caries

OBJECTIVE The aim of this study was to assess the exposure of patients to organic substances produced and identified in surgical smoke formed in the abdominal cavity during laparoscopic cholecystectomy. METHODS Identification of these substances in surgical smoke was performed by the use of gas

Porous organic cages composed of discrete cage molecules have attracted considerable recent attention as gas adsorption materials and separation media. In this study, we report a homochiral porous organic cage CC5 with a large cavity and pore windows as a novel stationary phase for high-resolution

The separation of styrene (St) and ethylbenzene (EB) mixtures is important in the chemical industry. Here, we explore the St and EB adsorption selectivity of two pillar-shaped macrocyclic pillar[n]arenes (EtP5 and EtP6; n = 5 and 6). Both crystalline and amorphous EtP6 can capture St from a St-EB

Molecular recognition underpins all specific protein-ligand interactions and is essential for biomolecular functions. The prediction of canonical binding poses and distinguishing binders from nonbinders are much sought after goals. Here, we apply the generalized replica exchange with solute

Benzene dioxygenase and toluene dioxygenase from Pseudomonas putida have similar catalytic properties, structures, and gene organizations, but they differ in substrate specificity, with toluene dioxygenase having higher activity toward alkylbenzenes. The catalytic iron-sulfur proteins of these

Aerobic oxidation of cyclooctane to its corresponding ol/one mixture at atmospheric pressure and in the liquid phase is efficiently promoted by an Fe(BTC) (BTC=1,3,5-benzenetricarboxylate) metal-organic framework, incorporating N-hydroxyphthalimide and in several cases reaches a selectivity over 90%

BACKGROUND Surgical smoke containing potentially carcinogenic and harmful materials is an inevitable consequence of surgical energy devices, and constitutes a substantial occupational hazard in the operating room. This study aimed to evaluate the efficacy of a built-in-filter trocar in eliminating

The majority of current micro-scale gas chromatography (μGC) systems focus on air sampling to detect volatile organic compounds (VOCs). However, purging the VOCs from a water sample using microsystems is an unchartered territory. Various organic compounds used in everyday life find their way to

Two novel triptycene quinoxaline cavitands (DiTriptyQxCav and MonoTriptyQxCav) have been designed, synthesized, and applied in the supramolecular detection of benzene, toluene, ethylbenzene, and xylenes (BTEX) in air. The complexation properties of the two cavitands towards aromatics in the solid

In 1977 Maltoni and Scarnato were the first to demonstrate that benzene is an experimental carcinogen in rats. With that and other experiments, Maltoni et al have shown that benzene administered by ingestion (stomach tube) or inhalation is a multipotential carcinogen in rats (of two different

Competitive recrystallizations of cholic acid (CA) from 1:1 binary mixtures of seven mono-substituted benzenes are demonstrated. The order of preference for guests to be incorporated into the cholic acid crystals are as follows: benzene, toluene > n-amylbenzene, n-hexylbenzene > ethylbenzene,

The potentials of mean force of homodimers of the molecules modeling hydrophobic amino acid side chains (ethane (for alanine), propane (for proline), isobutane (for valine), isopentane (for leucine and isoleucine), ethylbenzene (for phenylalanine), and methyl propyl sulfide (for methionine)) were

The oxidation by cytochrome P450cam (CYP101) of ethylbenzene and a series of substrates derived from it by addition of one, two, three, or four carbon atoms has been examined. For each of the 18 substrates, the shift in spin state due to substrate binding, the extent of coupled turnover to give

N,N'-Dithiobisphthalimide, C(16)H(8)N(2)O(4)S(2) (I), forms a wide range of polymorphs and solvates (pseudopolymorphs). When (I) is crystallized from methanol it yields a solvent-free polymorph (4), in Pna2(1) with Z' = 1, in which the molecules are linked into chains by a single C-H.O hydrogen

Henry's Law constants (HLCs) of several common, subsurface hydrophobic organic pollutants (HOPs) including trichloroethylene (TCE), perchloroethylene (PCE) and benzene, toluene, ethylbenzene, and o-xylene (BTEX), were measured using a static headspace phase ratio (SHPR) method over a range of
