The mechanical behaviors of five polyether block amide foams, obtained by mold-opening foam injection process, were investigated with regard to their microstructures. materials vary in mass ratios hard versus soft segments, and/or process packing time. resulting microstructures have been characterized terms cavity size and shape ratios, analyzing scanning electron microscope images after carefu...

Abstract Nano-Al 2 O 3 dispersion-strengthened Cu20W composite was fabricated by vacuum hot-pressing sintering process. The electrical conductivity, relative density, and Brinell hardness were tested, respectively. gleeble-1500D thermomechanical simulator used to conduct isothermal compression with strain rates ranging from 0.001 10 s −1 the temperatures 650 950°C. microstructure of Cu–Al /20W ...

Microalgae biomass has garnered significant attention as a renewable energy feedstock and alternative to petroleumbased fuels. The diverse metabolism of green microalgae species additionally provides opportunities for recovery of products for feed, food, nutraceutical, cosmetic, and biopharmaceutical industries. Recently, the concept of using microalgae as part of a biorefinery model has been a...

The possible application of a bacterial strain - Bacillus subtilis R1, isolated from an oil contaminated desert site in India, as biocontrol agent and its biosurfactant in microbial enhanced oil recovery are discussed. The biosurfactant production in minimal medium was carried out at different temperatures and salt concentrations, where it produced an efficient biosurfactant at 30-45°C and in p...

Takotsubo cardiomyopathy (TCM) is a clinical syndrome that commonly masquerades as acute coronary syndrome. Characteristically, TCM precipitated by stressful event and then diagnosed following demonstration of typical wall motion abnormalities in the absence obstructive artery disease. The transience left ventricular dysfunction, defined normalization ejection fraction (LVEF), has been hallmark...
