Nanocoatings have been prepared by dispersing two different surfmer-modified nanosilicate platelets into acrylic resins. UV-induced polymerization gave rise to highly crosslinked networks. The UV-curing kinetics was not affected by the presence of th

SYNOPSIS Two procedures of resin moulding powder preparation were evaluated. Their results are discussed on the basis of their tensile properties for moulded dumb-bells. The best procedure was then implemented for future work on phenolated pitch/ligi

SYNOPSIS Equal mixtures of phenosolvan pitch and autohydrolysis bagasse lignin in the presence of either acid or alkaline catalyst and without catalyst were submitted to a thermal treatment stage at 230°C (Phenolation). Each of the phenolated produc

Hollow-fibre carbon membranes with different pore sizes were tested as catalyst supports in the hydrogenation of CO. The factors which contributed to the uniformity of the porous structure and to an increase in the specific surface area of the membra

Away back in 1953 few people in the world, let alone South Africa, knew or had heard about membrane desalination, but there was an increasing awareness that electrodialysis had considerable potential for the desalination of brackish water. In South A

Incorporation of autohydrolysis bagasse lignin into phenol, cresylic acids novolac systems via the phenolation route and a pitched-lignin mixture for binders in cellulose-based composities was studied by differential scanning calorimetry (DSC)

The use of autohydrolisis bagasse lignin for incorporation into phenolic novolac systems lignin mixture used for binding of wood-like materials was studied. The phenolic raw materials selected were phenol and cresylic acids to confer special properti

Inhibition in Reversible Addition-Fragmentation chain Transfer (RAFT)-mediated polymerisations is currently a controversial issue; here we provide evidence that the slow "propagation" of the initiating and leaving group radicals during the early part

SYNOPSIS Mouldings of 25% resin content were prepared. Substitution of phenol novolac with various ratios of unmodified bagasse lignin was investigated. The effect of lignin incorporation on tensile and dimensional stability properties of mouldings w
