Three series of BiOM(x)R(1-x) (M, R = Cl, Br, I) solid solutions were systematically synthesized through a low-temperature precipitation. These solid solutions were characterized by XRD, FESEM, TEM, EDS, UV-vis spectra, nitrogen sorption/desorption, and PL. The tunable band gaps of the as-prepared solid solutions were realized via only changing the molar ratio of two halide ions. Meanwhile, the...

This work is aimed at the study and analysis of heat transport on a metal bar length L with solid-solid interface. The process assumed to be developed along one direction, across two homogeneous isotropic materials. Analytical numerical solutions are obtained under continuity conditions interface, that perfect assembly. lateral side isolated constant thermal source located left-boundary while r...

Simultaneous reactions between solids and gases are very important in the chemical and metallurgical processes. In the modeling, the chemical reaction and diffusion of gases must be considered. Therefore, a set of coupled partial differential equations is found. When the kinetic is a function of solid concentration, there is not any analytical solution for these equations. Therefore, numerical ...

The thermogravimetric analysis on TaC, HfC, and their solid solutions has been carried out in air up to 1400 ◦C. Three solid solution compositions have been chosen: 80TaC-20 vol % HfC (T80H20), 50TaC-50 vol % HfC (T50H50), and 20TaC-80 vol % HfC (T20H80), in addition to pure TaC and HfC. Solid solutions exhibit better oxidation resistance than the pure carbides. The onset of oxidation is delaye...

pyrophyllite solid solutions, AlrSi.-.Al,oro-.(oHr*"), have been synthesized from a gel and from lightly ground and milled natural materials. Solid solutions crystalliTe from structurally degraded or amorphous starting materials due to the tendency for Al3* to enter tetrahedral sites. The extent of solid solution is small; synthesis from a gel yielded pyrophyllite with the formula Al2 o(Si3 rAL...

Electron energy-loss spectroscopy (EELS) in combination with scanning transmission electron microscopy (STEM) reveals that the La enrichment at the surface of cerium-lanthanum solid solutions is an averaged effect and that segregation occurs in a mixed oxide phase. This separation occurs within a crystalline particle, where the dopant-rich phase is located at the surface of the dopant-deficient...

In 2005, 7.6 million people died of cancer out of 58 million deaths worldwide. Based on projections, cancer deaths will continue to rise with an estimated 9 million people dying from cancer in 2015, and 11.4 million dying in 2030. The increasing trend of cancer incidence has forced the humanity to work more on the cancer prevention and treatments. It is important for the public health professio...

We investigated the localized rotational diffusion of the (BH(4))(-) anions in LiBH(4)/LiI solid solutions by means of quasielastic and inelastic neutron scattering. The (BH(4))(-) motions are thermally activated and characterized by activation energies in the order of 40 meV. Typical dwell times between jumps are in the picosecond range at temperatures of about 200 K. The motion is dominated b...
