Magnesium borate(MB) istechnical ceramic for high heat-resisting, corrosion-resisting, super mechanical strength, superinsulation, light weight, high strength, and high coefficient of elasticity. Zinc borate (ZB) can be used as multi-functional synergistic additives with flame retardant additives in polymers. The most important properties are low solubility in water and high dehydration tempera...

gamma-Glutamyl transpeptidase, a membrane-bound enzyme, functions in the gamma-glutamyl cycle to catalyze utilization of glutathione. It has been postulated that the amino-acid-stimulated utilization of glutathione by gamma-glutamyl transpeptidase reflects an aspect of amino acid translocation. As one approach to the effective in vivo inhibition of this enzyme, the inhibition of the enzyme by L...

Here we discuss the thermodynamics of hydrolysis three borate-based lithium salts commonly used in aprotic electrolytes for lithium-ion batteries: tetrafluoroborate (LiBF 4 ), difluoro(oxalate)borate (LiODBF) and bis(oxalate)borate (LiBOB). We performed density functional theory calculations at ω B97M-V/6–31++G** level to compute thermodynamic stability reagents, intermediate products solution ...

Decay and mold resistance of zinc borate (ZB) and calcium borate (CB) modified oriented strandboard (OSB) from southern mixed hardwoods and yellow pine was investigated in this study. Tests were done with brown rot, Gloeophyllum trabeum, and white-rot, Trametes versicolar, fungi for 8 and 12 weeks, respectively. Wood species and fungus type had significant influence on the decay resistance. Dec...

PURPOSE Although all contact lenses (CLs) are applied initially to the eye directly from a packaging solution, little is known about the effects of these solutions on human corneal epithelial cells (HCECs). Due to the porous nature of CL materials, they have the potential to sorb components of the packaging solution during storage, which could then be subsequently released upon insertion of the...

A new nanosensor composed of laminated samarium borate and immobilized laccase was developed for phenol determination. The laminated samarium borate was synthesized by a mild solid-state-hydrothermal (S-S-H) method without any surfactant or Template. X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), and scanning electron microscopy (SEM) were used to characterize the samp...

The value assignment of candidate Standard Reference Material (SRM) 57b Silicon Metal provided an opportunity to develop an alkali reaction procedure as a precursor to borate fusion for the preparation of test specimens from the metal powder for X-ray fluorescence spectrometry (XRF). Suggested for this purpose by Blanchette (Adv. X-Ray Anal., 45, 415, 2002), the alkali reaction uses LiOH·H2O to...

Elongation factor T, (EF-T,) is inactivated by the arginine-specific reagent 2,3-butanedione. Excess elongation factor T, (EF-T,), the protein substrate for EFT,, protects EF-T, from this inactivation. Borate ion affects the inactivation kinetics in a manner consistent with the formation of an arginine residueebutanedione l borate complex. The butanedione inactivation is rapidly reversible in t...

A facile method for the synthesis of Zn2Al-borate and Mg3Al-borate layered double hydroxides (LDHs) with extremely high specific surface areas of 458.6 and 263 m(2) g(-1) and containing delaminated nanosheets is reported. To the best of our knowledge, this is the first report of LDH powders that still remain exfoliated on drying.

The Kırka borate deposit (Miocene), in western Turkey, the most important B2O3 producer at present in the world, exhibits a symmetrical zonation in a lateral sense; it is comprised of: a central body of Na borate (borax), an intermediate zone of Na–Ca borate (ulexite), and a marginal zone of Ca borate (colemanite). This mineral zonation is also developed in a vertical sense, although it is some...
