Ball on disc tribometer and atomic force microscopy (AFM) were used to analyse the effect of base oil polarity on the friction behaviour of steel–steel contacts lubricated with base oilzzinc dialkyldithiophosphate (ZDDP) solutions. Understanding the lubrication properties of the first chemisorbed layer of additives on work pieces yields important information for the optimisation of lubricant fo...

The life of quench oil is dependant upon its thermal stability. The thermal stability is a function of the quality of the base oil, the antioxidant package used, and the presence of heat and catalysts. In this paper, the mechanism of quench oil degradation and the function of antioxidants will be explained. An example of oxidation testing to determine the role of the base oil and antioxidants i...

Oil drill cuttings are challenging wastes in oil sites especially in Khuzestan province, a major oil producing region in Iran. As co- composting is a simple and eco- friendly technique for bioremediation of oil base drill cutting, this data article designed to describe co- composting of oil base drill cutting with cow manure. The data suggest that with optimized mixture of cow manure/oily drill...

This study setout to investigate the effect of wheat residue, tillage, and nitrogen fertilizer management on some agronomic traits of soybean as a split split plot based on randomized complete block design with three replications. The main plots included wheat residue management: collecting and leaving residue and sub plot included tillage (without tillage and conventional tillage), and the sub...

Bahrain is a very small oil-exporting country in the Middle East with a fixed exchange rate against the US dollar and has no restricton capital flows. Because its economy evolves around the oil sector, its economy is thought to be vulnerable to oil price movements. It is feared that the recent oil price hike would feed from foreign assets to monetary base and money supply to inflation. Empirica...

The WSe(2) nanorods were synthesized via solid-state reaction method and characterized by X-ray diffractometer, TEM, and HRTEM. The results indicated the WSe(2) compounds had rod-like structures with diameters of 10-50 nm and lengths of 100-400 nm, and the growth process of WSe(2) nanorods was discussed on the basis of the experimental facts. The tribological properties of WSe(2) nanorods as ad...

Trimethylolpropane triesters are biodegradable synthetic lubricant base oil alternative to mineral oils, polyalphaolefins and diesters. These oils can be produced from trimethylolpropane (TMP) and fatty acid methyl esters via chemical or enzymatic catalyzed synthesis methods. In the present study, a commercial palm oil derived winter grade biodiesel (ME18) was evaluated as a viable and sustaina...

Cinnamon leaf oil contains a high percentage of eugenol and has antimicrobial, antioxidant and antiinflammatory properties. However, the undiluted oil can cause irritation to the skin. Therefore, the aims of this study were to develop and evaluate cinnamon leaf oil nanocream using palm oil. Nanocream base was prepared using different ratios of oil, surfactants and water. The surfactant used wer...

Repellent properties of three plant extracts--essential oil (steam distillate) of Zanthoxylum limonella (fruits), Citrus aurantifolia (leaf) and petroleum ether extract of Z. limonella (fruits) were evaluated as repellent against Aedes (S.) albopictus mosquitoes in mustard (Dhara) and coconut (Parachute) oil base under laboratory conditions. Three concentrations--10, 20 and 30% of the repellent...
