Based on nonlocal piezoelasticity theory, dynamic stability of double-walled boron nitride nanotubes (DWBNNTs) conveying viscose fluid is studied by incorporating Euler–Bernoulli beam theory, Timoshenko beam theory, and cylindrical shell theory. The surface stress effects are considered based on Gurtin–Murdoch continuum theory.

Boron may be suitable for arthritis when taken in appropriate amounts. One study indicated that taking at least 3 milligrams per day of boron may have anti-inflammatory effects, which can help with osteoarthritis. It is also shown to positively impact the body's usage of testosterone, estrogen, and vitamin D. However, more research is …

The free vibration of a fluid-conveying nanotube composed of carbon nanotube and boron nitride (BN) nanotube is studied in this paper. The nonlocal Euler-Bernoulli beam model is adopted to describe the transverse displacement of the hybrid nanotube, and the governing equation is segmented because of the material properties' change at the junction. Then …

Some plant species produce significant amounts of polyol (eg sorbitol), making boron mobile in the phloem due to the formation and transport of boron sorbitol complexes. This mobility requires a constant, regulated supply of boron throughout the growing season to prevent toxicity in older leaves and deficiency in new, young leaves …

Wound Healing. Since 1990, boron has been shown to significantly improve wound healing. Application of a 3% boric acid solution to deep wounds reduced the time required in intensive care by two-thirds. 8 In 2000, in vitro research using human fibroblasts showed that a boric-acid solution improved wound healing through action on the extracellular …

A purer type of boron was isolated in 1892 by Henri Moissan. Eventually, E. Weintraub in the USA produced totally pure boron by sparking a mixture of boron chloride, BCl 3 vapour, and hydrogen. The material so obtained boron was found to have very different properties to those previously reported.

b). Plants where boron is mobile. Boron is highly mobile in plants that produce enough polyols (simple sugars) in primary photosynthetic processes. Such plants can mobilize it from one tissue to another where it requires it. These sugars bind with this nutrient forming a complex that can move in the phloem.
