The results of the identification of six sheet silicates originating from the Republic of Macedonia: chrysotile, Mg3Si2O5(OH)4; antigorite, (Mg,Fe2+)3Si2O5(OH)4; talc, Mg3Si4O10(OH)2; clinochlore, (Mg,Fe2+)5Al(Si3Al)O10(OH)8; cymrite, BaAl2Si2O8·H2O and montmorillonite, (Na...
MF:AlCaH2KNaO7Si2-2Molecular sieves, with the chemical formula Mx/nO·Al2O3·ySiO2·zH2O and CAS registry number 12173-28-3, are a class of crystalline materials known for their ability to selectively adsorb molecules based on size and shape. These materials consist of a three-dimensional ...
for C25H28O5S2Si2: C 56.78, H 5.34. X-ray quality crystals were grown from a CH2Cl2/ heptane solution. Dipropyl-2-(2,5-diethynyl-4-formylbenzylidene)-1,3-dithiole-4,5-dicarbox- ylate (8). A mixture of 7 (282 mg, 533 mmol) and K2CO3 (469 mg, 3.36 mmol) in dry THF (...
These interstitial point defects can also be categorized according to the occupied density of the W-S cell. The normal interstitial point defect means that the W-S cell is occupied by two atoms, e.g., (Si2)C, (SiC)C, (C2)C, (Si2)Si, (SiC)Si and (C2)Si. The high-density ...
During this process, the simulated susceptibility curve was automatically scaled to match the room temperature moment of the experimental data at each fit iteration, such that the shape of the temperature dependence could be accurately modelled to obtain a reliable measure of the splitting between the...
The electronic states of Si2 and Si2 as revealed by photoelectron spectroscopy We have measured the photoelectron spectrum of Si−2and find that the molecular electron affinity is EA(Si2)=2.199±0.012 eV. This spectrum apparently in... MR Nimlos,LB Harding,GB Ellison - 《Journal of Chemical...

Modeling growth in Si gas-source molecular beam epitaxy using Si2H6 Substrate temperature dependencies of growth rate and surface hydrogen coverage for Si GSMBE using Si H have been obtained experimentally. Validity of a gr... F Hirose - 《Journal of Crystal Growth》 被引量: 32发表: 1997年 ...
We report the release of catalytic DNA walkers from hydrogel microparticles and the detection of those walkers by substrate-coated microparticles. This might be considered a synthetic biology analog of molecular signal release and reception. One type of particles was coated with components of a DNA ...
Note that the slightly increases of Si2/(Si1 + Si2) intensity ratio (from 2% to 4% upon ZnO deposition) implies an abrupt ZnO/SiC interface. This is significantly different from what we observed in our previous study where the interface was formed by RF-sputtering the ZnO on the...
