Silicon carbide is widely appreciated for its high temperature strength, radiation tolerance and neutronic transparency in applications for fuel particles and core internals of nuclear reactors. In the Fluoride Salt-Cooled High Temperature Reactor, silicon carbide ceramic matrix composites are c...

Existing designs of reference electrodes for potentiometric measurements in fluoride melts do not meet basic requirements of the long exposure corrosion tests to be performed. A new diaphragm-free three-electrode meter with a nonstationary (dynamic) beryllium reference electrode for the redox po...

The aim of this article is to give an overview of the coordination chemistry of beryllium. The unique properties of the Be2 + cation, due to its extremely high charge density, are emphasized and a comprehensive overview of complexes with the most common donor ligands is given. Additionally the a...

Next-generation nuclear reactor concepts and advanced techniques for reprocessing spent nuclear fuel (SNF) are drawing great attention in the nuclear field. Molten halide salts have been proposed as the fuel solvent and coolants for many molten salt reactor (MSR) concepts, and the electrolyte fo...

This chapter describes the strong and weak interactions of beryllium to form covalent bonds and beryllium bonds. We start from the challenging description of bonding in the beryllium dimer, trimer and larger clusters, followed by a brief review of other beryllium-beryllium bonds and organoberyll...

Cosmogenic beryllium-7 has been widely employed as a sediment tracing tool and continued development of its use as a soil erosion tracer requires knowledge of fallout temporal dynamics. Data regarding beryllium-7 fallout in the UK are scarce and here the authors provide a record of beryllium-7 f...

Synergistic therapeutic potential of ferritin (5 mg/kg, i.p.) and propolis (honeybee hive product; 200 mg/kg, p.o.) was analyzed to encounter the beryllium induced biochemical and ultra morphological alterations. Female albino rats were exposed to beryllium nitrate (1 mg/kg, i.p.) daily for 28 d...

Five sealed plutonium–beryllium (PuBe) neutron sources from various manufacturers were disassembled. Destructive chemical analyses for recovered PuBe materials were conducted for disposition purposes. A dissolution method for PuBe alloys was developed for quantitative plutonium (Pu) and berylli...

The feeding of powdered leaves of Gymnema sylvestre in the diet of rats for 10 days prior and 15 days after i.v. beryllium nitrate significantly protected the animals from the full fall of blood glucose seen in rats receiving beryllium nitrate alone. The feeding of the leaves for 25 days to norm...

The valence band density of states of bulk beryllium nitride (alpha-Be3N2) and the solvation energy of hydrogen atoms in this nitride is herein studied using the generalized gradient approximation density functional theory. The DOS is compared to photoelectron spectroscopy investigations of nitr...

Beryllium is a critical material for many strategic industries. It is widely used despite its relatively high cost because it performs better in certain critical applications than its alternatives. The beryllium industry produces three primary forms of beryllium: copper-beryllium alloy is the la...

In this study, tannic acid functionalized graphene as an adsorbent was synthesized and characterized by X-ray diffraction and scanning electron microscopy. It was used for the first time as an adsorbent for vortex-assisted dispersive solid phase extraction of trace Be(II) from water and street d...

The vaporization of 20–50 μg beryllium from nitrate solution was observed in graphite furnace atomizers using pyrocoated and Ta-lined tubes. A charge coupled device (CCD) spectrometer was employed to follow the evolution of absorption spectra (200–475 nm), the light scattering and emission. M...

Beryllium has a unique combination of properties which has made it a vital component in a wide range of technical sectors and consumer industries. However, beryllium is extremely toxic and can cause chronic beryllium disease, for which there is no current cure. The toxicity of beryllium has limi...

The 2,6-diphenyl-4-benzo-9-crown-3-pyridine (DPCP) was used as an excellent ionophore in construction of a coated graphite poly(vinyl chloride) (PVC)-based membrane sensor. The best performance was obtained with a membrane composition of 30% poly(vinyl chloride), 60% o-nitrophenyloctyl ether (NP...

Trace amounts (0.004–0.55 ng) of beryllium (Be) in a dried bovine liver sample (20 mg) can be accurately determined by graphite-furnace atomic absorption spectrophotometry (GFAAS) after treating with microwave digestion (HNO3/H2O2) at 85 °C for 10 min and using acetylacetone as a chelating age...

Beryllium dust will be produced under plasma interaction with beryllium armor of the first wall in ITER. Exothermal reaction of this dust with water steam or air, which can leak into the reactor vacuum chamber in some accidents, gives concern in respect to reactor safety. Results of studies devo...

Two beryllium complexes Be[(R2N)2P(O)F]4(ClO4)2 (R = Me (1) and R = Et (2)) were synthesised and characterised by multinuclear (31P, 19F and 9Be) NMR, IR and elemental analyses. Solution 9Be NMR spectra of the two complexes show sharp quintuplets due to coupling with four equivalent phosphorus a...

The aqueous coordination chemistry and the structural chemistry of beryllium are reviewed focusing on simple fluoride, aquo, hydroxo, oxo, and peroxo complexes. Complex formation with the heavier halide and chalkogenide anions plays no role in aqueous solution. Formation and structure of berylli...
