BACKGROUND Individuals with axillary hyperhidrosis have much higher than average sweat rates and are often prescribed anhydrous aluminum chloride (AlCl(3)) solutions. Topical application of these solutions can be irritating to the skin, resulting in poor compliance and lower than desired efficacy. OBJECTIVE Demonstrate the efficacy of an over the counter "clinical strength" soft-solid antiper...

structurally different trimethyl silyl ethers are oxidized with bu4/nio4 in the presence of alcl3 and bf3 as catalysts in ch3cn and chcl3 under reflux conditions. the corresponding carbonyl compounds are isolated in good yields.

introduction: colloidal materials and suspended solids cause turbidity in water. to remove turbidity, clarification method is used that includes processes of coagulation, flocculation, and sedimentation. due to the long duration of coagulation process, coagulant aids are applied. despite the favorable efficiency of synthetic polyelectrolytes as a coagulant aid, due to their harmful effects on h...

An anticorrosion layer is a significant component that prevents the corrosion process in materials. In this work, nanofiber of poly (methyl methacrylate) composited with few-layer-graphene was prepared as an layer. electrospinning applied to prepare composite on metal substrate at various concentrations few-layer graphene. The physical properties were investigated field-emission scanning electr...

High-quality AlN layers with thickness up to 50 mm have been grown by HVTE at growth rates up to 60mm/h at deposition temperatures of 1000–11001C in the pressure range of 50–760Torr. The HVT process uses an aluminum chloride amine adduct as the aluminum source and ammonia for the nitrogen. This new technique eliminates the main difficulties of the conventional HVPE growth, where aluminum oxidat...

Ab initio and density functional methods have been employed to study bridge bonding of aluminum compounds. Results for geometry optimizations and vibrational frequency calculations are found to be consistent with the recent literature. Heats of formation for the aluminum compounds dimethylaluminum hydride and trimethylaluminum are poorly described with density functional theory (DFT) methods in...

Bifunctional aluminum is prepared by sulfating aluminum metal with sulfuric acid. The use of bifunctional aluminum to degrade methyl tert-butyl ether (MTBE) in the presence of dioxygen has been examined using batch systems. Primary degradation products were tert-butyl alcohol, tert-butyl formate, acetone, and methyl acetate. The initial rate of MTBE degradation exhibited pseudo-first-order beha...

the reaction of readily available 1 -methyl-4-nitropyrrole-2- carboxylic acid (1) with thionyl chloride afforded the corresponding acyl chloride 2. the reaction of compound 2 with thiosemicarbazides yielded 1-(1 -methyl-4-nitrop yrrole-2-carbony1)- thiosemicarbazides (3) which cyclized in basic medium to 5-(1-methyl-4-nitropyrrole- 2-y1)-2,4-dihydro-3h- l,2,4-triazole-3- thione 4. alkylation an...

Oxaliplatin is a platinum-based anticancer drug used to treat metastatic colorectal, breast, and lung cancers. While oxaliplatin kills cancer cells effectively, it exhibits several side effects of varying severity. Neuropathic pain is commonly experienced during treatment with oxaliplatin. Patients describe symptoms of paresthesias or dysesthesias that are triggered by cold (acute neuropathy), ...
