Introduction to Low Boron

SEM analysis of the surface of the partially oxidized diamonds revealed that the low boron content (0.

The determination of low boron concentrations in silicate glasses by electron probe microanalysis (EPMA) remains a significant challenge.

The measured asymptotic hardness value of MnB4 is far higher than that of low boron concentration manganese borides counterparts.

These results further suggest that ultrathin borophene ribbons can be grown at low temperature and low boron chemical potential.

(CA)] under moderate and low boron (B) conditions.

At very low Boron concentration, bulk resistivity values ≫100 Ω-cm are achieved and an effective lifetime above 1 ms is measured, corresponding to an estimated bulk lifetime around 2 ms.

The results show that refreshing solution every 24 h produced the fastest HAp formation for low boron-containing samples when SBF was used as testing solution, while no significant differences were observed when K2HPO4 solution was used.

The nonappearance of boron deficiency on sunflower, when grown on low boron sandy soil, was investigated to test the validity of this boron guideline fertility.

A wide range of substrate temperatures and boron fluxes have been explored, revealing that high crystalline quality hBN layers are grown at high substrate temperatures, $>$1600$^\circ$C, and low boron fluxes, $\sim1\times10^{-8}$ Torr beam equivalent pressure.

We find that at low boron percentages, the direct bandgap decreases slightly and then increases toward the large minimum direct gap of BAs as more boron is added.

For low Boron catalysts, the addition of Nickel to Cobalt nanoparticles improves the catalytic activity in ethanol steam reforming allowing yields as high as 87% at 773 K, at high space velocities (GHSV 324,000 h−1).

BN platelets were firstly stacked into hollow boron nitride microbeads (BNMB) via salt-template method; then, the as-prepared BNMB were further compressed and infiltrated with epoxy resin.

This situation also states that a higher boron content is not the sole factor for the higher hardness in the low boron content transition metal borides.

In this study, the hardening behavior of Ni-B thin films with ultra-low boron contents is investigated by synchrotron X-ray diffraction and high resolution transmission electron microscope (HR-TEM).

Contrary to common understanding, the hardness of TaB is higher than that of TaB2 , which indicates that low boron concentration borides could be mechanically better than the higher boron concentration counterparts.

This hardening and the thermal stability of the novel [am + bcc + fcc] structures are remarkable at such low boron content and encouraging for development as ultrahigh-strength alloys.

It is found that conductivity of BZO films, especially with a low boron doping level, can be enhanced significantly after annealing in hydrogen, and moreover, the total transmittance (TT) and haze factor of the H2-annealed BZO films were still almost unchanged simultaneously, which were attributed to phenomena of an increase in carrier mobility with an almost constant of free carrier concentration.

Higher boron contents led to an amorphous nano-carbon, while a few-layered NB-GNs was obtained at low boron content in the ACN reaction mixture.

However, boron-containing drugs such as L-boronophenylalanine (BPA) and sodium borocaptate (BSH) have low boron content and/or poor tumor-targeting ability, limiting their application.

Originality/value Low boron solution could protect carbon steel from the attraction of corrosive ions by forming a passive film with Fe-O-B structure.

In certain geographies, the saline groundwater possesses high boron concentration which is incompatible with the field fracking chemicals; hence, a low boron concentration is desired.
