Various types of zero, one, and two-dimensional boron nanomaterials such as nanoclusters, nanowires, nanotubes, nanobelts, nanoribbons, nanosheets, and monolayer crystalline sheets named borophene have been experimentally synthesized and identified in the last 20 years. Owing to their low dimensionality, boron nanomaterials have different bonding configurations from those of three-dimensional b...
Boron is a trace mineral which is found in highest amounts in fruits, vegetables, nuts, and legumes. Although it has not been demonstrated unequivocally to be an essential nutrient for humans, increasing evidence indicates that boron deficiency and supplementation exert measurable biological effects. Boron has been shown to impact mineral metabolism, brain function and performance, and selected...
We use scanning tunneling microscopy and X-ray spectroscopy to characterize the atomic and electronic structure of boron-doped and nitrogen-doped graphene created by chemical vapor deposition on copper substrates. Microscopic measurements show that boron, like nitrogen, incorporates into the carbon lattice primarily in the graphitic form and contributes ~0.5 carriers into the graphene sheet per...
Growing demand for water desalination promoted the vigorous development of reverse osmosis (RO) membrane. How to effectively remove boron from seawater is key problem be solved by RO It important select suitable membrane materials experimental design before complicated and expensive attempts. In this paper, we demonstrate that pore chemistry plays a role in removal capability membranes via none...
Lettuce, which is being grown in ever increasing quantities, suffers from a number of nutritional disorders which have been the subject of considerable speculation and study. Much of the difficulty with lettuce is evidently the result of the type of forcinig culture which is used to obtain the most firm and succulent heads. Among the micro-nutrient elements, boron has been given considerable at...
