single crystal zno microrods are deposited on the surface of zn plate through corrosion of zn plate by h2o2, which is a green neutral reagent and easy to transform to h2o and o2. the structure and morphology of the obtained zno microrods were characterized by x-ray diffraction (xrd), scanning electron microscopy (sem), transmission electron microscopy (tem) and electron diffraction. a thermodyn...
Continuous pathways that connect different crystal structures can play a crucial role in determining the mechanisms with which structural phase transformations occur. The number of known connecting metallic phases, such as Bain path and Burgers path, are limited. Here we discover six new BCC, FCC, HCP ω to more complex intermetallic compound structures. High throughput first-principles calculat...
Two new organic–inorganic salts of perhalidometallates with protonated organic amine cations have been synthesized and characterized by X-ray diffraction thermal analysis. (CHBMAH2)ZnBr4·3/2H2O 1 (CHBMAH2)ZnCl4 4 [(CHBMAH2)2+: 1,3-cyclohexanebis(methylammonium)] were obtained in single-crystal form. The crystal packing all the compounds is governed formation various non-covalent intermolecular ...
run-out-table (rot) is located between last finishing stand and down coiler in a hot strip mill. as the hot steel strip passes from rot, water jets impact on it from top and bottom and strip temperature decreases approximately from 800-950 °c to 500-750°c. the temperature history that strip experience while passing through rot affects significantly the metallurgical and mechanical properties, s...
A series of MOFs constructed from 5-((carboxymethyl)amino)isophthalic acid (H 3 cmai) have been prepared and characterised, with [Cd (cmai) 2 O) 4 ]·4H O demonstrating loss water in a single-crystal-to-single-crystal transformation.
The anisotropy exhibited by single-crystal silicon in nanometric cutting is very significant. In order to profoundly understand the effect of crystal anisotropy on cutting behaviors, a large-scale molecular dynamics model was conducted to simulate the nanometric cutting of single-crystal silicon in the (100)[0-10], (100)[0-1-1], (110)[-110], (110)[00-1], (111)[-101], and (111)[-12-1] crystal di...
