The mechanical properties of commercially pure titanium can further be improved through the grain refinement processes; however, welding fine-grained materials is challenging due to coarsening in weld area and hence weakening locally. Meanwhile, friction stir a promising process which metallurgical bonding established solid-state mixing welded; no studies have reported ultra-fine-grained commer...

This paper reported the results of research into effect Equal Channel Angular Pressing (ECAP) temperature and 1-h annealing on mechanical properties, stress-relaxation resistance, corrosion resistance austenitic steel AISI 321L with strongly elongated thin δ-ferrite particles in its microstructure. The formation α′-martensite fragmentation austenite grains takes place during ECAP. Ultrafine-gra...

Umbelliferone β-D-galactopyranoside (UFG), isolated from plants, exhibits promising inhibitory action on numerous diseases. The present research was initiated to develop a suitable delivery system for UFG with an intention to enhance its therapeutic efficacy against diethyl nitrosamine (DEN)-induced hepatocellular carcinoma (HCC) in Wistar rats. UFG-loaded polymeric nanoparticles prepared by so...

twenty four samples of xenoliths and country rocks from the 1961 lava flow of calbuco volcano have been studied. fourteen samples have been analyzed for major elements and p, ni, ba, cr, v, zr, sc, y, and sr. five of these samples were further analyzed for sm, nd, sr, and pb isotope ratios. seventeen samples were analyzed under the microscope and three samples were analyzed by microprobe for th...

The Upper Fremont Glacier (UFG), Wyoming, is one of the few continental glaciers in the contiguous United States known to preserve environmental and climate records spanning recent centuries. A pair of ice cores taken from UFG have been studied extensively to document changes in climate and industrial pollution (most notably, mid-19th century increases in mercury pollution). Fundamental to thes...
