A main property of the electronic band structure of the lead salt compounds is the small and direct energy gap of less than 410 meV (see Table 1). Since the maxima of the valence band and the minima of the conduction band are located at the same wavevector in reciprocal space, optical ...
Transition metalSubstitutional dopingO-2 adsorptionMoS2Based on first-principles calculations, the effects of substitutional doping with transition-metal (TM) atoms (Co, Ni, Ru, Rh, Pd, Ir, Pt and Au) were investigated on the electronic structure, magnetic property and chemical activity of the ...
”) The property of chemical inertness is of special importance in metallurgy and glassmaking, where the furnaces are exposed to extremely corrosive molten materials and gases. In addition totemperatureandcorrosionresistance, refractories must possess superior physical wear orabrasionresistance, and they ...
Among alkali earth metals, the reactivity with hydrogen increases in the sequence: intactilibrium hydride is the least stable while radium hydride is the most stable. Compounds of heavier alkaline metals calm as hydrides have the property to act as reducing agents in different types of chemical pr...
and a few American natives. Afire piston that produced heat and fire by the compression of air in a small tube of bamboo was a complex device invented and used in southeastern Asia, Indonesia, and the Philippines. About 1800 a metal fire piston was independently invented in Europe. In 1827...

As per specifications from the International Union of Pure and Applied Chemistry [1], the ideal sensor is “a device that transforms chemical information, originating from a chemical reaction of the analyte or from a physical property of the investigated system, ranging from the concentration of a...
curvature in the CNS prepared from leaves indicates the presence of more macropores than the CNS prepared from the stems. This more pronounced adsorption property in the isotherms of CNS from leaves is assigned to an enhanced N2uptake associated with micropore filling....
