The solubilities in the three-component systems MIO3–Be(IO3)2–H2O (M = K, NH4+, Rb, Cs) were studied at 25 °C by the method of isothermal decrease of supersaturation. It has been established that double salts, K2Be(IO3)4·2H2O, (NH4)2Be(IO3)4·2H2O, and Rb2Be(IO3)4·2H2O, crystallize from the...

The Tran and Blaha modified Becke-Johnson potential TB-mBJ embedded in the WIEN2K code are used to calculate structural, electronic and linear optical properties of two isostructural iodates: TlIO3 and α-RbIO3. We have found that the computed structural properties are in good agreement with the...

Rubidium and cesium amidoboranes were obtained using a reaction of the respective alkali metal with ammonia borane in THF solution at 0 °C. Both solid compounds undergo a reversible phase transition before irreversible thermal decomposition with hydrogen evolution, as illustrated by STA, PXRD a...

We present the results of studies of alkali hydride formation in vapor cells under laser irradiation. Two mechanisms are studied: formation in the cell volume in the presence of hydrogen and formation on the laser irradiated cell window. The first mechanism is investigated in a room-temperature ...

In this study, the effectiveness of several alkali metal hydrides (KH, RbH and CsH) for improving the hydrogen desorption properties of a 2LiNH2/MgH2 mixture was studied. Results showed that the relative effectiveness of these additives in decreasing the hydrogen desorption temperature, lowering...

Aqueous RbF solutions have been investigated at ambient conditions by dielectric relaxation spectroscopy (DRS) over the concentration range of 0 ≤ c/M ≤ 5 and by statistical mechanics (RISM integral equation theory) in the concentration range of 2.15–9.18 M. The behavior of the dielectric spe...

Seawater reverse osmosis (SWRO) brine management is essential for desalination. Improving brine recovery rate with resource recovery can enhance the overall desalination process. In this study, an integrated submerged membrane distillation (S-MD) with adsorption (granular potassium copper hexacy...

The liquid + liquid phase equilibrium of molten mixtures of lithium fluoride with potassium and rubidium halides was investigated over an extended temperature range in the two-phase region along the saturation line by the electrical conductivity method. In the overwhelming majority of mixtures, ...

The heat capacities of cesium and rubidium dichromates have been measured by differential scanning calorimetry (DSC) in the temperature range 310–610 K. These values have been combined with measured and estimated values for the standard entropy and enthalpy of formation of Cs2Cr2O7 and Rb2Cr2O7...

The Solubility, density and refractive index of the formamide(FA)/N-methylformamide(NMF)/N,N-dimethylformamide(DMF) + rubidim bromide/cesium bromide+ water ternary systems were determined at (283.15, 298.15 and 313.15) K. The solubility of the RbBr and CsBr decrease significantly when adding ami...

The key element in the Proton-Driven-Plasma-Wake-Field-Accelerator (PWFA) project is the generation of highly uniform plasma from Rubidium vapor. A scientifically straightforward, yet highly challenging way to achieve full ionization is to use high power laser which can assure the barrier suppre...

The heat capacities of cesium and rubidium chromates have been measured by differential scanning calorimetry (DSC) in the temperature range 350–780 K. These values have been combined with measured and estimated values for the standard entropy and enthalpy of formation for Cs2CrO4 and Rb2CrO4 to...

Synthesis and crystallographic data are reported for a family of double rubidium-rare earth chromates RbLn(CrO4)2, where LnLaLu, Y and Sc. The compounds are closely related to the potassium chromates KLn(CrO4)2 but with a slightly different distribution of structural types: those of La, Pr a...

Cyanide has been used for more than a century as a preferred lixiviant for extracting gold from ores and concentrates. While cyanide is very effective in treating certain ores and concentrates, it is not suitable for carbonaceous and high copper-bearing ores. Research activities over many decade...

Sulfated polysaccharides (SPSs) are polysaccharides (PSs) with high sulfate functionalization and possess bioactivities. This study aimed to increase the sulfate content of SPSs in Antrodia cinnamomea through sulfate feeding. Feeding A. cinnamomea with sodium thiosulfate was found to increase yi...

In recent years, the heavy metal ions have been immoderately released into the ecological system and result in potential hazardous to public health. Herein, the sodium dodecyl sulfate intercalated molybdenum disulfide (SDS-MoS2) was synthesized for the adsorption of Cr(VI). The SDS molecule was ...

Tripodal, tetradentate tetraphosphine ligand tris(1H-2-diisopropylphosphinoimidazol-1-yl)phosphine (1) was synthesized in three straightforward steps from widely available starting materials. The ligand crystallized in a C3-like conformation suitable for metal coordination. Nickel(II) complex 2 ...

Polypyrrole/molybdenum disulfide (PPy/MoS2) composites were synthesized by in-situ chemical polymerization of pyrrole in the presence of MoS2 flakes. The conductivity of the composite with a moderate content of PPy (15–30 wt%) reached 13 S cm−1, which is markedly higher than the conductivity of...
