In this study, an optimized vortex-assisted method for rapid screening of oil content in Jatropha curcas L. (Jatropha) seeds is described. A 24-1IV fractional factorial design was employed to study the influence of vortex stirring rate, sample:solven

The method of extraction of phorbol esters from Jatropha curcas L. (Jatropha) seed was optimized, using an experimental design, and validated in this study. Variables such as extraction time, vortex-stirring rate, sample:solvent ratio, solvent type a

Polymeric materials are increasingly used in several applications. However, their relatively high flammability presents a danger to people and property. Their use therefore requires that they are made more resistant to both the initiation and propaga

Sub-micron thick flakes were obtained by sonication of vermiculite that was first exfoliated by either thermal shock or chemical treatment with hydrogen peroxide. Dimer fatty acid polyamide nanocomposites with a mixed morphology were prepared via a s

Replacing the exchangeable interlayer ions in Palabora vermiculite with magnesium, aluminum or iron (III) ions does not affect the exfoliation onset temperature (456 ± 11 °C). However, co-intercalation of minor amounts of urea lowers the exfoliatio

The utility of expandable graphite as a flame retardant for PVC, plasticized with 60 phr of a phosphate ester, was investigated. Cone calorimeter results, at a radiant flux of 35 kW m −2 , revealed that adding only 5 wt.% expandable graphite lowere

South African Palabora vermiculite was modified by ion exchange with ammonium and selected alkali metal and alkaline earth metal ions. In the exchanged vermiculite with ammonium ions, it was found that ammonia and water were the blowing agents and th

The effect of marbles and granites on the plasticity and bending stress of two Mozambican clays (OUA and CIMOC) was studied. For that purpose, clay masses with addition of marble and granite rejects have been prepared, their plasticity and mechanical

Background The insecticide dichloro-diphenyl-trichloroethane (DDT) is widely used in indoor residual spraying (IRS) for malaria control owing to its longer residual efficacy in the field compared to other World Health Organization (WHO) alternatives.
