boron (b) is a non-metal micronutrient which is essential for plants growth and development. formation of boron complex with cell wall matrix and phenolic compounds is a definite influence of boron in physiological process. it has been suggested that b-toxicity and deficiency may induce excess production of reactive oxygen species thereby promote defense responses by antioxidant enzymes or non-...

Aqueous sodium borohydride (NaBH4) is well known for its reducing property and well-established for the development of metal nanoparticles through reduction method. In contrary, this research paper discloses the importance of aqueous NaBH4 as a precipitating agent towards development of porous zirconium oxide. The boron species present in aqueous NaBH4 play an active role during gelation as wel...

cotton (gossypium hirsutum l. cv. varamin ) an important industrial crop of iran, is grown in 300,000 ha, with an average seed -cotton yield of 1750 kg.ha-1. the main obstacle in the way of increasing average cotton yield is imbalanced fertilizer use. along with urea and triple super phosphate, cotton growers also need k, mg, zn, fe, mn, cu, and b, so these elements’ critical levels should ...

Boron is an interesting element with unusual polymorphism. While three-dimensional (3D) structural motifs are prevalent in bulk boron, atomic boron clusters are found to have planar or quasi-planar structures, stabilized by localized two-center-two-electron (2c-2e) σ bonds on the periphery and delocalized multicenter-two-electron (nc-2e) bonds in both σ and π frameworks. Electron delocalization...

Borocaptate sodium (Na2B12H11SH) is a potentially useful compound for boron neutron capture therapy of intracranial tumors. Tumor and normal tissue boron concentrations were evaluated in 30 dogs with naturally occurring intracranial tumors after i.v. borocaptate sodium infusion (55 mg boron/kg). Postmortem tissue boron concentrations were measured for three postinfusion time periods (2, 6, and ...
