Giorgia Pastorin in Boron Nitride Nanotubes in Nanomedicine 2016 Boron nitride nanotubes (BNNTs) have recently emerged as an intriguing source of excitement because they enable the realization of advanced integrated and compact nanocomposites to be fabricated What renders these nanomaterials so special is the similarity of boron nitride atoms to carbon in terms of

Note that each boron atom in the B 12 icosahedron is connected to five other boron atoms within the B 12 unit (a) The allotrope of boron with the simplest structure is α-rhombohedral boron which consists of B 12 octahedra in an almost cubic close-packed lattice (b) A side view of the structure shows that icosahedra do not pack as

The ability to prepare controllable nanocatalysts is of great interest for many chemical industries Atomic layer deposition (ALD) is a vapor phase technique enabling the synthesis of conformal thin films and nanoparticles (NPs) on high surface area supports and has become an attractive new route to tailor supported metallic NPs Virtually all the studies reported focused on Pd NPs

Novel π-conjugated boron polymers containing transition metals in the main chain were prepared by hydroboration polymerization between tetrayne monomer including metal complex and tripylborane From gel permeation chromatographic analysis (THF PSt standards) the number-average molecular weights of the polymers obtained were found to be 9 000

We describe a simple and clear picture of electronic bonding in boron sheets and highlight the importance of three-center bonding and its competition with two-center bonding which can also explain the stability of recently discovered boron fullerenes Our findings call for reconsideration of the literature on boron sheets nanotubes and clusters

Boron removal was evaluated in the present work by using calcium alginate beads (CA) and a novel composite based on alginate–alumina (CAAl) as sorbents in a batch system The effects of different parameters such as pH temperature contact time and composition of alginate (at different concentrations of guluronic and mannuronic acids) on boron sorption were investigated

Hydrogen-boron fusion is one example In principle the fusion reaction between nuclei of hydrogen and boron could provide a highly efficient radioactivity-free form of nuclear energy with practically unlimited fuel reserves The reaction produces no dangerous penetrating radiation and no radioactive waste but only stable alpha particles

Highly porous sponge‐like boron nitride materials namely microsponges (BNMSs) with ultrahigh surface areas up to 1900 m 2 g ‐1 are prepared by a facile one‐step template‐free reaction of boric acid and dicyanamide Detailed analysis confirms the increase of the interlayer (0002) distances compared to standard graphitic BN and reveals special dislocation structures

The average cost of crystalline boron is $5/g Free boron is chiefly used in making boron fibers where it is deposited by chemical vapor deposition on a tungsten core (see below) Boron fibers are used in lightweight composite applications such as high strength tapes This use is a very small fraction of total boron use Boron is introduced

INTRODUCTION Produced water includes water trapped in underground formations and water injected into the stratum to drive out the crude oil (Deng et al 2002) It is separated from crude oil above ground in an oil/water separator (Murray-Gulde et al 2003) In early stages of oil production water content is usually low but can rise to as high as 80% during the later years of

Boron is a chemical element with symbol B and atomic number 5 Produced entirely by cosmic ray spallation and supernovae and not by stellar nucleosynthesis it is a low-abundance element in the Solar system and in the Earth's crust Boron is concentrated on Earth by the water-solubility of its more common naturally occurring compounds the borate minerals

Folic acid (FA) has high affinity for the folate receptor (FR) which is limited expressed in normal human tissues but over-expressed in several tumor cells including glioblastoma cells In the present work a novel pteroyl–closo-dodecaborate conjugate (PBC) was developed in which the pteroyl group interacts with FR and the efficacy of boron neutron capture therapy (BNCT)
