The thermochemical emission of alkali metals from biomass samples and two organic salts was investigated for the first time using a novel combination of a th ermogravi metric analyzer with a jet flow condenser attached to a surface ionization detector. Thi ...
Highly selective separation of yttrium (and lanthanides) is of interest for the design of radiopharmaceuticals, and an efficient method based on the ion-imprinting concept is proposed here. The synthesis and structural, thermodynamic and photophysical char ...
This paper presents the results of an experimental program designed to assess the durability of sisal and coconut fibres exposed to alkaline solutions of calcium and sodium hydroxide. In addition, the durability and microstructure of the cement mortar comp ...
Large-scale, ultralong ZnO nanowire and nanobelt arrays with honeycomb-like micropatterns have been fabricated by hydrothermal oxidation of zinc foil in aqueous alkaline (NH4)2S2O8 solutions. ...
H-1, P-31, and Li-7 pulsed-gradient spin-echo (PGSE) diffusion and variable-temperature NMR results for THF solutions of the lithium and potassium salts derived from diphenylphosphino(o-cyanophenyl)aniline are reported and compared to the solid-state resul ...
This paper reports a novel topotactic exchange reaction of the ethylenediammonium intercalated mixed-valent vanadyl phosphate, (H3NCH2CH2NH3)0.5[V4+0.45V5+0.55O2PO4{P(OH)2}0.483], with monovalent cations at room temperature. Alkali metal ions and other mon ...
Salt effects exerted on the cycloetherification of linear diarylheptanoid 3-OH-4-MeOC6H3(CH2)2COCMe2CO(CH2)2C6H3-3-F-4-NO2 were investigated. Both salting-in and salting-out alkali salts were found to inhibit the macrocyclization. Ion-pairing exchange was ...
There is considerable interest in synthetic ionophores with high affinity and selectivity for Li+. But so far, compounds that selectively bind Li+ in the presence of other alkali and alkaline earth metal ions are rare and current approaches toward this goa ...
The novel fast-growth or multiple steering mol. dynamics (MSMD) technique has been recently developed by Jarzynski to calc. free energy profiles along general transformation pathways (Phys. Rev. Lett. 1997, 78, 2690-2693; Phys. Rev. E 1997, 56, 5018-5035). ...
Chloro- and hydrido-complexes of ruthenium(II) with potassium (4-diphenylphosphino)benzenesulfonate (pTPPMS) were prepared and their properties were compared with those of the related complexes of (3-diphenylphosphino)benzenesulfonates. An X-ray crystal st ...
