Bulk metallic glass-forming Pd40Ni10Cu30P20 has been investigated in its equilibrium liquid by quasielastic neutron scattering. The quasielastic signal exhibits a structural relaxation as known from nonmetallic viscous liquids. Even well above the melting point, the structural relaxation is nonexponential and obeys a universal time-temperature superposition. From the mean relaxation times avera...

Traditional analysis of reactions catalyzed by supported metals involves the structure of the metallic particles. However, we report here that for the class of nanostructured gold- or platinum-cerium oxide catalysts, which are active for the water-gas shift reaction, metal nanoparticles do not participate in the reaction. Nonmetallic gold or platinum species strongly associated with surface cer...

This article talks about the territories of Uzbekistan, which are rich in ore and nonmetallic minerals, lists measures for rational use available mineral raw materials Fergana Valley, particular Namangan region, development on this basis regions construction industry.

Mukaiyama s classic catalytic asymmetric aldol reaction with enolsilanes has been improved upon over the years; now new approaches to the reaction have been developed. Those reviewed here are the use of new transition metal based catalysts for the aldol reaction using silyl enolates, the use of other O-silylated nucleophiles, tin-modified or even unmodified ketones as substrates, and the use of...

Separation of various chemical components from each otheJO is often the most difficult step in analytical procedures. The problems attached to separation become further magnified when the species concentations are extremely low. A group of techniques that has proven useful especially in dilute solutions for separating and concentrating metallic as well as nonmetallic ions and complexes, protein...

introduction and goal: today, the researchers have found that many recent diseases are due to cellular oxidative stress which is caused by the imbalance of the formation and neutralization of free radicals. including weak immune system, cancers, inflectional diseases, aging body and diabetes. diabetes is the most common endocrine disease in the world that is referred to as the mother of the dis...
