In the borate transporter BOR1, which is located in the plasma Arabidopsis membrane, is degraded in the presence of excess boron by an endocytosis-mediated mechanism. A similar mechanism was suggested in rice as excess boron decreased rice borate transporter levels, although in this case whether the decrease was dependent on an increase in degradation or a decrease in protein synthesis was not ...
A highly sensitive electrochemicalimmunosensor was developed to detect hCG based on immobilization ofhCG-antibody (anti-hCG) onto robust nanocomposite containing Gr, Chit,1-methyl-3-octyl imidazolium tetra fluoro borate ionic liquid (IL)(Gr-IL-Chit). AuNPs were used to immobilize hCG antibody on the modifiedelectrode. The amine groups of the antibody are cova...
The crystal structure of the title compound, [Ni(6)(C(13)H(10)NO(2))(4)(N(3))(8)(CH(3)OH)(8)]·6CH(3)OH, consists of a centrosymmetric hexa-nuclear [Ni(II) (6)(C(13)H(10)NO(2))(4)(N(3))(8)(CH(3)OH)(8)] mol-ecule and six methanol solvent mol-ecules. In the hexa-nuclear unit, the six octa-hedrally coordinated Ni(II) atoms are linked by four μ(1,1,1)-azide and four μ(1,1)-azide bridges, forming a f...

For the first time, we give a fundamental understanding of the effect of borate-modified nanodiamond on propane oxidative dehydrogenation reaction. Upon increasing the loading amount of borate on the carbon surface, the propene selectivity shows a volcanic curve. The adsorption sites of borate at different loading amounts are thoroughly considered.
A number of new charge-neutral zwitterionic tris(methimazolyl)borate ligands have been synthesized, either by substitution of the dimethylamine group in the adduct (dimethylamine)tris(methimazolyl)borane (1) or by insertion into its B-N(dimethylamine) bond by an unsaturated Lewis base. Two new anionic ligands, (thiocyanato)tris(methimazolyl)borate and (cyano)tris(methimazolyl)borate, have also ...
A tris-borate buffer solution of = 0.1 and pH 8.9 is shown to be satisfactory for use in the elect-rophoresis of human and bovine sera by the moving-boundary technic. Comparison of the patterns obtained by the use of tris-borate and barbital buffer is presented. Similar numbers of electrophoretically distinct components are found by the use of either buffer. Although the calculated mobility of ...
The abiotic origin of genetic polymers faces two major problems: a prebiotically plausible polymerization mechanism and the maintenance of their polymerized state outside a cellular environment. The stabilizing action of borate on ribose having been reported, we have explored the possibility that borate minerals stabilize RNA. We observe that borate itself does not stabilize RNA. The analysis o...
The donor properties of a series of tripodal mixed N-donor/carbene ligands derived through sequential alkylation of hydrotris(1,2,4-triazolyl)borate have been investigated by density functional theory (DFT) methods. The structures of complexes of the form [Mo(L)(CO)3] were optimized (L = [HB(1,2,4triazolyl)n(1,2,4-triazol-5-ylidene)3-n] (n = 0 – 3), hydrotris(pyrazolyl)borate, hydrotris(3,5dime...
Chloramine-T and sodium borate solutions were evaluated for their effectiveness in preserving Mycobacterium bovis and controlling the growth of non-mycobacterial contaminants on tissue specimens during transport to laboratories. The number of culturable M. bovis cells in suspension was reduced by 5.1 log10 upon exposure to chloramine-T solution and by less than 1 log10 upon exposure to sodium b...
