BACKGROUND AND AIMS Kaolin applications have been used to mitigate the negative effects of water and heat stress on plant physiology and productivity with variable results, ranging from increased to decreased yields and photosynthetic rates. The mechanisms of action of kaolin applications are not clear: although the increased albedo reduces leaf temperature and the consequent heat stress, it al...

In this research, the amount of Iron removal by bioleaching of a kaolin sample with high iron impurity with Aspergillus niger was optimized. In order to study the effect of initial pH, sucrose and spore concentration on iron, oxalic acid and citric acid concentration, more than twenty experiments were performed. The resulted data were utilized to train, validate and test the two layer artificia...

Concerns are being raised that microplastic pollution can have detrimental effects on the feeding of aquatic invertebrates, including zooplankton. Both small plastic fragments (microplastics, MPs) produced by degradation of larger plastic waste (secondary MPs; SMPs) and microscopic plastic spheres used in cosmetic products and industry (primary MPs; PMPs) are ubiquitously present in the environ...

receiving full dose heparin (A kaolin clotting time; 56, 29, and 19 seconds) and four had been considered to have equivocal lupus inhibitor tests. On testing of subsequent samples from three of the equivocal patients, one with a A kaolin clotting time of 29 seconds was found to have a definite lupus inhibitor while the two others (19 and 14 seconds) were negative. The A kaolin clotting time in ...

Zonous Kaol ini te bea ring c lay de pos it is made by hydrothermal alteration of volcanic rocks mainaly of andesite ami dacite. Kao linit e , quartz and calci te are the main mineral co mposi tions. As quart z in the volcanic roc ks is cryptocrys talline, it is too dificult to seperat e it from kaol inite. The phys ical properties and chemica l composition of Zonous ceramic grade kaolinit...

Clay minerals are one of the most utilized among non-metals. These hydrous aluminum silicates with a layer (sheet-like) structure. Kaolin is aluminosilicate mineral thin platelet extensively used in paper, paint, and many other industries. Wet processing kaolin will not be sustainable over long term because global freshwater resources becoming scarce. Hence, process necessary that does consume ...

The leafhopper Scaphoideus titanus is the vector of 'Candidatus Phytoplasma vitis', the causal agent of Flavescence dorée (FD) a key disease for European viticulture. In organic vineyards, the control of S. titanus relies mostly on the use of pyrethrins that have suboptimal efficacy. During 2016, three field trials were conducted to evaluate the efficacy of kaolin, orange oil, insecticidal soap...

Cement is proven increasing the strength of soft clays. Monmorillonite has a high shrinkage. Another hand, Kaolin small Waste material usage for stabilization agent was widely carried out this decade. BAFA (bottom ash fly ash) and POFA (palm oil fuel are rich in Silica Alumina, so they used to substitute cement. The study examined effect Monmorillonite, Kaolin, on clay with Bentonite from 4% 16...
