Although boron has long been known to be a required nutrient for plants, it was not until recently that there was any suggestion of a nutritional requirement for animals and humans. Addition of boron to the diet of vitamin D-deficient chicks indicated that boron may play a role in animal nutrition. Studies with rats have demonstrated that supplemental dietary boron has most marked effects when ...

BACKGROUND A column sorption study was carried out using calcium alginate gel beads as adsorbent for the removal of boron from aqueous solutions. The breakthrough curve was obtained as a function of pH, initial concentration of boron, feed flow rate, adsorbent mass and column diameter. The breakthrough capacity values and adsorption percentage of calcium alginate gel for boron were...

The chemistry of boron azides, first reported by E. Wiberg et al. in 1954 [1], was further investigated by P. I. Paetzold [2 4], and the field has been reviewed [5, 6]. Structural and spectroscopic data for boron dichloride azide (trimeric) [7, 8] and dimethylboron azide have been reported in the literature [9]. Quite recently, additional boron azides have been reported and structurally charact...

The presence of small amounts of boron in ductile iron is reported to have multiple and sometimes conflicting effects on the mechanical properties of ductile irons. The technical literature up until the early 1990’s states that small amounts of boron is a powerful carbide stabilizing element. Boron levels as low as 0.001% (10 ppm’s or parts per million) stabilize pearlite but larger amounts wer...

The micronutrient boron is essential in maintaining the structure of plant cell walls and is critical for high yields in crop species. Boron can move into plants by diffusion or by active and facilitated transport mechanisms. We recently showed that mutations in the maize boron efflux transporter ROTTEN EAR (RTE) cause severe developmental defects and sterility. RTE is part of a small gene fami...

The measurement conditions for determining boron using graphite furnace-atomic absorption spectrometry (GF-AAS) were investigated. Differences in the boron absorbance profiles were found using three different commercially available GF-AAS instruments when the graphite atomizers in them were not tuned. The boron absorbances found with and without adjusting the graphite atomizers suggested that a...

We employ X-ray absorption near-edge spectroscopy at the boron K-edge and the phosphorus L2,3-edge to study the structural properties of cubic boron phosphide (c-BP) samples. The X-ray absorption spectra are modeled from first-principles within the density functional theory framework using the excited electron core-hole (XCH) approach. A simple structural model of a perfect c-BP crystal accurat...

Boron nitride (BN)-based nanomaterials attract considerable attention due to their unique properties. In this study, we found that sonication treatment of multiwalled boron nitride nanotubes (BNNTs) in primary alcohols had led to chemical peeling of their sidewalls through alcoholysis, thereby producing boron nitride nanoribbons (BNNRs).
