High-voltage nickel-rich layered cathodes possess the requisite, such as excellent discharge capacity and high energy density, to realize lithium batteries with higher density. However, materials suffer from structural interfacial instability at voltages (>4.3 V). To reinforce stability of these cathode elevated voltages, borate salts are investigated electrolyte additives generate a superior c...

Borate is an essential material to numerous industries and even individual countries’ economies, defense, politics. Almost all need borates for production, almost everybody needs their products. a compound that contains or supplies boric oxide (B2O3). Among the minerals contain oxide, there are only four significant from economic standpoint, namely borax (tincal), colemanite, ulexite, kernite. ...

A novel potentiometric ion-selective PVC membrane sensor for analysis of atorvastatin (AT) in pharmaceutical preparations based on atorvastatin-(tetraphenyl borate), (AT-(TPB)2) as sensing element, tetraphenyl borate as additive and tris-2-ethyl-hexyl phosphate (TOP) as plasticizer solvent was prepared. The electrode shows a good Nernestian response over the concentration range of 0.09–5586 µ...

A new 3D lead borate Pb(6)B(6)O(14)(OH)(2)(H(2)O), built by different cluster building units of B(6)O(14)(OH) {B(6)} and Pb(6)O(5)(OH) {Pb(6)}, has been obtained under mild hydrothermal conditions. Each {B(6)} cluster is linked with seven {Pb(6)} clusters and vice versa that give rise to the first 7-connected lead borate network.

The title compound, [Na(C(16)H(36)BO(4))](n), has a fourfold axis passing through the Na and B atoms which both are bound by four O atoms. The tetra-butoxy-borate anion provides the bridging to form one-dimensional polymers running along [001], just like those found for the tetra-ethoxy-borate structure. The two but-oxy 'tail' atoms are disordered over two conformations in a 0.887 (9):0.113 (9)...

This study evaluated leaf supply of zinc (Zn) and boron (B) using either soluble or sparingly fertilizers in young sweet orange trees. Three experiments were set up a greenhouse to compare two sources four doses (control, low, adequate high) as follows: (i) Experiment I (B): boric acid calcium borate; (ii) II (Zn): Zn sulfate oxide; (iii) III (B + Zn): Sulfate Borate. The effective increasing t...

Solvent mixtures containing trimethyl borate virtually eliminated the pronounced interconversion of 1,2- and 1,3-dipalmitins during their resolution by thin-layer chromatography on Silica Gel G. With trimethyl borate, an average of 1-2% of 1,2-dipalmitin was converted to 1,3-dipalmitin. A four-directional-development TLC procedure incorporating trimethyl borate resolves cholesteryl glucoside, c...

Foragers of the Formosan subterranean termite, Coptotermes formosanus Shiraki, were allowed to tunnel in two dimensional, sand filled arenas containing Douglas-fir (Pseudotsuga menziesii [Mirb.] Franco) wafers pressure treated with disodium octaborate tetrahydrate (DOT) to an average retention of 1.77% BAE on one side of each arena, and untreated wafers of Douglas-fir on the other side. Arenas ...

1-Ethyl-3-methylimidazolium bis(oxalato)borate ([Emim][BOB]), a room-temperature ionic liquid, has been prepared and used for the first time to develop new borate-containing material. A new open-framework cobalt borophosphate, (NH(4))(7)Co(4)(H(2)O)[B(2)P(4)O(15)(OH)(2)](2)[H(2)PO(4)][HPO(4)], with peanut shaped extra-large 16-ring channels has been obtained.

Electrolysis of Co(2+) in phosphate, methylphosphonate, and borate electrolytes effects the electrodeposition of an amorphous highly active water oxidation catalyst as a thin film on an inert anode. Electrodeposition of a catalytically competent species immediately follows oxidation of Co(2+) to Co(3+) in solution. Methylphosphonate and borate electrolytes support catalyst activity comparable t...
