In order to prepare polyurethane elastomers with acceptable physical properties and good biocompatibility, novel polyurethane networks were synthesized via curing reaction of epoxy-terminated polyurethane prepolymers (EUPs) with hexamethylene diamine. EUPs were prepared from reaction of glycidol with NCO-terminated polyurethanes (ITPs). ITPs were also synthesized from reaction of one equi...

Al(OH)3 nanoparticles were synthesized by a simple precipitation reaction. The effect of various amines like ethylene diamine, propylene diamine, triethylenetetramine and tetraethylenepentamine as precipitating agents on the morphology of Al(OH)3 nanostructures was investigated. The influence of Al(OH)3 nanoparticles on the flame retardancy of the poly vinyl alcohol (PVA) matrix was studied usi...

Within ten days of incubation, freshly ripe tomato fruits (Ibadan local variety) obtained from a local market in Ile-Ife, Osun State, Nigeria had completely deteriorated and proteins which possessed cellulolytic activity were released. The enzyme was partially purified by a combination of ammonium sulphate precipitation, molecular exclusion chromatography and ion-exchange chromatography. The en...

Titrimetric estimation of calcium with disodium ethylene diamine tetra-acetate (E.D.T.A., sodium edetate), as performed on serum (Baron and Bell, 1957), cannot be applied directly to most other biological specimens because of their high concentration of phosphate. A high ratio of phosphate to calcium in the material titrated causes a drawnout and inaccurate endpoint. A rapid procedure for calci...

Dithiocarbamates are highly versatile, mono-ionic chelates that form stable complexes with many transition metals and main group elements. Ccmplexes of cobalt(II) piperidine dithiocarbamate and diamines such as Ethylene diamine, Diethylene triamine and Triethylene tetramaine have been synthesised . The complexes have been characterized by IR , UV-Vis and EPR spectral studies , Thermal and magne...
