Effect of chemical modification on the flow and electrical properties of neem oil derivatives

ABDELMALIK A. A^*, Umar Shehu, Sadiq U.

Seed oil has been proposed as alternative base fluid for drilling mud but its stability to oxidation is still an issue to deal with. This paper reports the influence of stabilizing neem oil through chemical modification on its flow and electric conduction properties. Ester derivatives were produced from laboratory purified neem oil. The purified ne...

Properties of chemically modified Baobab pod/Sisal Fibre reinforced Low Density Polyethylene Hybrid Composite

ISA M. T^*, Umar Shehu, Aderemi B. O., Bello T. K., Audu H. I., Umar Shittu Muhammad, ATTA A. Y

The present study determined the effect of sodium hydroxide (NaOH) treatment on the properties of baobab pod/sisal fibres reinforced low-density polyethylene (LDPE) hybrid composites. Used to treatment the fibres, were different concentrations of NaOH 2 -10 wt% at 2 wt% interval. The hybrid composites were compounded using two roll mills machine an...
