The Influence of Silicon and Boron on the Electrochemical Behaviour of Ab,-hydrides
نویسنده
چکیده
AB,-type intermetallic compounds were prepared by induction melting and melt spinning. The composition of a stoichiometric compound LaNi,,,Co,.,Mn,,,Al,.~ with a hexagonal CaCu, structure was varied by &i&&metric and nonstoichiometric addition of Si and B. Discharge capacity is increased considerabdy by addition of silicon in the range of 0.5-5 at% with a maximum value at about 1%. The highest capacity is achieved by a nonstoichoimetric addition of 3 at% Si. The kinetic properties are additionally improved by the formation of a boron-rich second phase.

Ab initio random structure searching.
It is essential to know the arrangement of the atoms in a material in order to compute and understand its properties. Searching for stable structures of materials using first-principles electronic structure methods, such as density-functional-theory (DFT), is a rapidly growing field. Here we describe our simple, elegant and powerful approach to searching for structures with DFT, which we call a...

The successive droughts and the degradation of water and soil resources quality (salinity and toxicity of nutrients like boron) are serious challenges for tropical fruit tree cultivation such as mango in Hormozgan province south of Iran. Using some nutrients like silicon is believed to be effective in order to mitigate the aforementioned problem. Hence, an experiment was carried out in which si...
متن کاملChange of diffused and scattered light with surface roughness of p-type porous Silicon
Porous silicon samples were prepared by electrochemical etching method for different etching times. The structural properties of porous silicon (PS) samples were determined from the Atomic Force Microscopy (AFM) measurements. The surface mean root square roughness (σ rms) changes as function of porosity were studied, and the influence of etching time on porosity and roughness was studied too. U...
