Post-consumer glass represents a major component of solid waste. On the other hand, more than 100 million tons of coal combustion ash are generated in the U.S. annually, of which 60 million tons are fly ash. To deal with these problems, two new materials were developed: “glascrete” and “ashcrete.” They have the potential of being made almost entirely from recycled materials: crushed mix-color w...

corrosion makes huge economic and ecologic damage all over the world. biologic corrosion of sewer pipes is considered as a serious limitation in economic perspectives. to prevent biologic corrosive damage, lining techniques can be applied by materials and aggregate resistant to attack bacterially in sewer pipes. the role of bacteria is that they convert sulfur compounds into sulfuric acid which...

An oxetane derived from d-xylose has been copolymerised with CS2 into sulfur-containing polymers which are chemically recyclable and degradable under UV light.

In this report, we describe a potential drug interaction between niacin and the hepatic radiopharmaceutical technetium-99mlabeled sulfur colloid ~9mTc-SC). A patient was admitted with a diagnosis of acute hepatitis caused by her sustained-release niacin therapy. Diffuse lung accumulation of mTc-SC was seen on her liver/spleen images. This is the first report of pulmonary localization of 9mTc-SC...

Theoretical ab initio quantum mechanical charge field molecular dynamics (QMCF MD) has been applied in conjunction with experimental large angle X-ray scattering (LAXS) to study the structure and dynamics of the hydrated thiosulfate ion, S2O3(2-), in aqueous solution. The S-O and SC-ST bond distances have been determined to be 1.479(5) and 2.020(6) Å by LAXS and to be 1.478 and 2.017 Å by QMCF ...

Chronic high surface ozone (O3) levels and the increasing sulfur oxides (SOx = SO2+SO4) ambient concentrations over South Coast (SC) and other areas of California (CA) are affected by both local emissions and long-range transport. In this paper, multi-scale tracer, full-chemistry and adjoint simulations using the STEM atmospheric chemistry model are conducted to assess the contribution of local...

In this data article experimental data on the compressive strength, and the durability of styrene and bitumen modified sulfur concrete against acidic water and ignition are presented. The percent of the sulfur cement and the gradation of the aggregates used are according to the ACI 548.2R-93 and ASTM 3515 respectively. For the styrene modified sulfur concrete different percentages of styrene ar...

One of the effective ways to increase durability building products and structures operating under influence aggressive media is using sulfur binders manufacture concretes. It shown that chemical resistance concretes a greater extent depends on matrix composition. was found introduction modified additives increases their resistance. With optimal content additives, water composites from 2.3 3.2 t...
