Boron is an essential element for plants but is toxic in excess. Therefore, plants must adapt to both limiting and excess boron conditions for normal growth. Boron transport in plants is primarily based on three transport mechanisms across the plasma membrane: passive diffusion of boric acid, facilitated diffusion of boric acid via channels, and export of borate anion via transporters. Under bo...

Layered Ni-rich materials for lithium-ion batteries exhibit high discharge capacities but degraded cyclability at the same time. The limited cycling stability originates from many aspects. One of critical factors is intrinsic insulating residual lithium compounds and rock-salt (NiO) phase on surface particles. In this work, LiNi 0.8 Co 0.1 Mn O 2 material etched with a trace amount boric acid u...

zinc sulphate and boric acid ophthalmic preparations, containing benzalkonium chloride as preservative, have been investigated against gram-negative and positive bacteria. viability of bacteria was found after 7 days, although it was completely suppressed after 24 hours of inoculation. zinc sulphate generally increases the antimicrobial activity of benzalkonium chloride, whereas boric acid or i...

Our previous work demonstrated substantial accumulation of allantoate in leaf tissue of nodulated soybeans (Glycine max L. Merr., cv Williams) in response to nitrogen fertilization. Research was continued to determine the effect of nitrate and asparagine on ureide assimilation in soybean leaves. Stem infusion of asparagine into ureide-transporting soybeans resulted in a significant increase in ...

Borated water leakage through spent fuel pools (SFPs) at pressurized water reactors is a concern because it could cause corrosion of reinforcement steel in the concrete structure and compromise the integrity of the structure. Because corrosion rate of carbon steel in concrete in the presence of boric acid is lacking in published literature and available data are equivocal on the effect of boric...

A facile strategy based on the reaction of urea and boric acid is developed for the synthesis of toxicity-free BCNO nanocrystals containing carbon impurities and which exhibit efficient multi-color fluorescence under both single-photon and two-photon excitation.

Laboratory colonies of the ghost ant, Tapinoma melanocephalum (F.) were administered sugar solution (10%) baits containing the insecticides boric acid, fipronil (REGENT), hydramethylnon (SIEGE), or diflubenzuron (DIMILN). Colonies were exposed to the baits for 21 d, and development of workers, queens, and brood (larvae and pupae) was observed for 4 wk. Fipronil (0.05%) caused 100% mortality in ...

Background: Boric acid (BA) is commonly used as pesticide, disinfectant and wood preservative. Its ingestion can cause serious organ damages resulting in death. Case report: A 19 year old man was found dead with two empty packs of BA tablets in vicinity of his body. On autopsy examination, brownish stains along with right angle of mouth and right nostril were found. Stomach was damaged with hem...
