Samples were analyzed using an electron microprobe for major elements, ion microprobe for C-O-H volatiles, and Fourier transform infrared spectroscopy for molecular H 2O, OH , molecular CO 2, and CO 3 2. CO 2 solubility was determined in hydrous andesite glasses and we found that H 2O ...
溶解液中的Li +和Co 2+用40%N aOH 溶液为沉淀剂进行分离。Co(OH)2沉淀先经过提纯,提纯后的试样在300 下煅烧2h,可回收得到Co 2O 3。Co 的回收率可达96%,其纯度达到99 2%。母液中L i +加固体Na 2CO 3处理,沉淀后重结晶,得到L i 2CO 3。Li 的回收率可达到74%,纯度达98 6%。关键词:锂离子电池;...
In this work, we aim at further improving the pseudo-capacitive behavior for Co(OH)2/GNS electrode through adding K3Fe(CN)6 into KOH electrolyte, based on that Fe(CN)63−/Fe(CN)64− redox pair has a high solubility and electrochemical activity. Our findings are that Fe(CN)63−/Fe...
since N2molecule has an exceedingly high dissociation energy for the triple bond (941 kJ mol−1) and an inferior solubility in water (6.24 × 10−4mol L−1atm−1)24,25,26. Although direct reaction between adsorbed N2and CO was...

Similarly, a sparingly soluble salt such as Ca(OH)2 exhibits a high solubility as the amount of glycerol is increased in a glycerol-water mixture [51]. However, the dissociation constant of Ca(OH)2 decreases with glycerol addition, indicating that its dissociation is limited in the water-...
The solubility of maleic anhydride in supercritical carbon dioxide was directly measured by sampling and analyzing the supercritical phase. The observed sharp increase in the apparent rate constant of the reaction between maleic anhydride and isoprene correlates with the solubility of maleic anhydride in ...
(g:ml). For this extraction, a buffer without sodium or potassium ion was recommended for SDS-PAGE analysis because those cations reduce the solubility of DS (dodecyl sulfate). Before centrifugation, a TritonX100 (25%, v/v) was added to a portion of leaf homogenate to make a final ...
In vivo ribosomal protein solubility assay. The sqt1 mutant cells, either containing empty vector or a centromeric plasmid expressing Sqt1 from the ADH1 promoter, were grown in a volume of 100 ml to an OD600 of B0.7 and expression of C-terminally 2xHA-tagged Rpl10 was induced for 20 min...
Also, solubility of copoly- amides rich in the APE component would be superior to that of copolyamides rich in the PD component. As a result, increasing ratios 100 Monomer Copolymer TPA PD/PD+APE moll- 1 mol/mol 0.21 0 0.21 0.2 0.21 0.4 0.21 0.6 0.21 0.8 0.21 1.0 Yield IJ,vfcb PD...
