The growing global demand for renewable energy sources can be reached using biofuels such as biodiesel, example. most used route to produce biodiesel is the transesterification reaction of oils or fats with short-chain alcohols, generating fatty acid esters (biodiesel) and a very important by-product, glycerol (Gly). Gly widely in different sectors industry, order add value this heterogeneous c...

The paper reviews data on biological side-effects of dental materials on patients and also on personnel who routinely handle the materials. The incidence of adverse effects is low--in one study indicated to be 1:700 for all types of treatments. For individual types of materials, it will be significantly lower, and for restorative materials, probably in the 1:10,000 to 1:20,000 range. Allergic r...

A hierarchical computational approach is introduced that combines materials screening with process optimization. This approach leads to novel materials for cost-effective CO2 capture. Zeolites are screened using shape, size, and adsorption selectivities. Next, process optimization is introduced to generate a rank-ordered list based on total cost of capture and compression. We not only select th...

Growing demand for road infrastructures and accompanying environmental footprint calls the replacement of pavement materials with recycled options. The complexities in real-world usability are dependent upon project-specific characteristics affected by budgetary constraints local governmental agencies, material applicability, climatical conditions. This study conducts a comprehensive lifecycle ...
