Lead free, eco-friendly bismuth borate glasses doped with alkali oxides of composition xLi2O+(30-x)Na2O+55B2O3+15Bi2O3 (x = 5,10,15,20,25) were prepared by melt quenching technique. Amorphous nature of glasses was confirmed by X-ray diffraction. Density measurements were carried out at room temperature by standard principle of Archimedes with Xylene as an immersion liquid. The non-linear ...
Negative ion photoelectron spectra are reported for the heteronuclear alkali dimer and trimer anions, NaK-, KRb-, KCs-, RbCs-, Na$-, and KzCsat 488 nm. In addition to assigning all ofthe electronic transitions observed in the mixed dimer anion spectra, vertical detachment energies, adiabatic electron affmities, and dimer anion dissociation energies have also been determined. A linear correlatio...
one of the most commonly used techniques to reduce the corrosion rate of rebar in concrete is addition substances named corrosion inhibitors into the concrete. corrosion inhibitor is chemical compounds that were added to concrete to prevent corrosion of steel in concrete. sodium nitrate is a type of anodic inhibitors that this study investigatesthe effect of this inhibitor on the properties of ...
Mixed hardwood chips were treated with lignin-degrading fungi to study the effect of fungal pretreatment on bleaching characteristics of kraft pulp. Pretreated wood chips were subjected to reduced active alkali doses in comparison to untreated chips. Comparable results were obtained for pretreated chips with reduced alkali dose as was obtained with higher dose of alkali in case of untreated chi...
Thua nao was a Thai alkali fermented product from soybean by Bacillus and it had a special flavour and aroma. The microorganisms involved in traditional thua nao were mixed natural flora of Bacillus, B. subtilis, B. megaterium and B. cereus, contaminated from cooked soybeans. The product had a very strong smell of ammonia. Ammonia content in dried product was lower than in the wet product. The ...
