Adsorption of PEO/PPO triblock co-polymers and wetting of coal
(Elsevier, 1999-01)
The adsorption characteristics of PEO/PPO/PEO triblock co-polymers on coal were investigated using surface tension and contact angle measurements. Although these surfactants have been widely used as wetting agents, it was ...
Kinetics of oil dispersion in the absence and presence of block copolymers
(American Institute of Chemical Engineers, 1999-09)
A phenomenological model proposed describes droplet breakup in the turbitlently agitated lean oil-in-water dispersions and provides a correlation between the median droplet size in an agitated vessel of standard geometry ...
Synthesis and characterization of a new mono-molybdenated metallo-ligand [Mo{HB(3,5-Me2C3HN2)3}(NO)Cl(OC 6H4PPh2-p)]
(Taylor & Francis, 1999)
The "metallo-ligands" can be considered effectively as a modified triphenylphosphine ligand, and used to generate novel transtion metal complexes in which electron-transfer and magnetism is embedded within the stable ligand ...
Hydrogen sulfide determination by solid surface luminescence
(Springer, 1996)
In the analytical system suggested, atmospheric hydrogen sulfide reacts with the surface of a filter paper treated with aqueous cadmium chloride and yields a luminescent species whose intensity can be correlated with the ...
Determination of plutonium in seawater using co-precipitation and inductively coupled plasma mass spectrometry with ultrasonic nebulisation1
(Elsevier, 1998-07-06)
A flow injection–inductively coupled plasma–mass spectrometric (FI–ICP–MS) procedure, utilising ultrasonic nebulisation with membrane desolvation (USN/MD), has been developed for the determination of plutonium (Pu) in ...
A novel sorbent tube for ambient hydrogen sulfide determination
(Elsevier, 1998-11)
A novel tubular device has been developed for hydrogen sulfide determination in air. Several substrates such as commercial silica gel and alumina TLC plates, silica gel powder, alumina, CaSO4, CaCO3, BaSO4, MgO, chalk, ...
Determination of technetium in sea-water using ion exchange and inductively coupled plasma mass spectrometry with ultrasonic nebulisation†
(Royal Society of Chemistry, 1998-09)
An enrichment–separation scheme employing a strong-base type anion-exchange resin was developed for the determination of99Tc in sea-water by inductively coupled plasma mass spectrometry utilising ultrasonic nebulisation ...
Synthesis and characterization of amido and amido(monoalkylamido)nitrosyl-[tris(3,5-dimethylpyrazolyl)borato]molybdenum complexes
(Taylor & Francis, 1997)
The chloro-amido complex [Mo{HB(3,5-Me2C3HN2)3}(NO)Cl(NH 2)] was prepared by treating [Mo{HB(3,5-Me2C3HN2)3}(NO)Cl 2] with an excess of ammonia. The monoalkylamido complexes [Mo{HB(3,5-Me2C3HN2)3}-(NO)(NH 2)(NHR)] (R = Me, ...
Synthesis, characterization and reactivity of [exo-nido-Rh(PPh3)2(η5-C2B 9H10Me2)]
(Taylor & Francis, 1996)
In this work, the reaction of the 16-electron species [Rh(η3-C8H13)-(η5-C 2B9H9Me2)] with PPh3 was investigated and the product, [exo-nido-Rh-(PPh3)2(η5-C2B 9H10Me2)], which is in an equilibrium with the closo analogue was ...
