This study assessed 3D WO3–TiO2 nanoflowers (WTNF) synthesized by a combined hydrothermal–ultrasonication–impregnation method for their applicability to the treatment of aromatic volatile compounds under visible-light illumination. The scanning electron microscopy exhibited the formation of 3D structures in the prepared WTNF samples. The X-ray diffraction patterns and energy dispersive X-ray re...

N-F-co-embedded titania (N-F-TiO₂) photocatalysts with varying N:F ratios were synthesized and tested for their ability to photocatalyze the degradation of pollutants present at indoor air levels using visible light. The synthesis was achieved using a solvothermal process with tetrabutyl titanate, urea and ammonium fluoride as sources of Ti, N and F, respectively. Three selected volatile organi...

Submit Manuscript | http://medcraveonline.com it can replace toluene where slower drying is desired. It is also a powerful cleaning agent, e.g., for silicon wafers, circuits and steel [1,2]. Toxicity of xylene in lung, thymus, liver and skin has been reported [3,4]. The nephrotoxicity of xylene has not been well documented. Cortical tubular epithelial cells are a vulnerable site of organic solv...

In a series of experiments to investigate interactions between industrial solvents and common medications the interaction between m-xylene and aspirin was studied. As both these substances are metabolised and excreted as glycine conjugates there would possibly be competition for this conjugation pathway. Five male volunteers were exposed on separate occasions to m-xylene by inhalation (100 ppm)...

The solvents o-, m-, p-xylene, p-dichlorobenzene, 1,2,4-trichlorobenzene, and naphthalene were calibrated as condensates used in the thermoporosimetry technique. Exponential relationships were found connecting the pore radii R(p) (in nm) and the freezing-point depression of the swelling solvent deltaT (in degrees C) on the one hand and the apparent energy of crystallization W(a) (in J cm(-3)) a...

background: xylene is known as one of the most toxic of the nervous system. the purpose of this study is to estimate the concentration of xylene in the cabin of the vehicles production in iran. also the effect of ventilation, cigarette smoking, and air freshener inside the vehicle, fuel type and car decorations on the concentration of the substance being studied.   methods: 152 vehicles pride a...

The title 22-crown-6 unit, C(26)H(28)O(6), comprising of three benzo groups and triethyl-ene glycol, was prepared by the reaction of α,α'-dibromo-p-xylene with 1,8-bis-(2-hydroxy-phen-oxy)-3,6-dioxaoctane in the presence of Cs(2)CO(3) with tetra-hydro-furan (THF) and recrystallized from dichloro-methane-hexane (1:20 v/v) at room temperature. In the mol-ecular structure, two O atoms of the centr...

Distribution of Inhaled m-Xylene in Rat Brain and its Effect on GABAA Receptor Binding: Takehiko ITO, et al. Faculty of Education, Okayama University—Organic solvents generally depress the central nervous system (CNS), similarly to volatile anesthetics. The precise mechanism of their action on the CNS, however, is not fully understood, and remains to be clarified. This study is focused on how i...

OBJECTIVES Ethanol may be a significant combined factor in human solvent toxicity. Lipid peroxidation has been suggested to be an important contributing mechanism involved in experimental alcohol-induced liver injury. The aim of the study was to investigate whether a short-term ethanol ingestion in rats chronically exposed to m-xylene vapor may influence the lipid peroxidation rate in the intra...
