background and objectives : zeolite is a group of anionic hydrated aluminosilicates with a tridimensional structure which has great implications in remediation of water, sediment and soil resources. the present research aims at physicochemical investigation, clay mineralogy and micromorphology of soils along rafsanjan-sarcheshmeh lithotoposequence, southeastern iran. materials and methods: the ...

Adhesion and homogeneity of the coating-substrate were analyzed on basis establishment coating mineralogy. Substrate raw materials used kaolin clay a calcined alumina 4 µm; series higher density ceramic coatings deposited using aluminas 0.5 µm µm, silica fume, talc. The dip technique was applied to all substrates later sintered at 1300 ºC. Shrinkage mixtures substrate separately evaluated. X-ra...

Cost-effective, clean, highly transparent, and flexible as well a coatable packaging material is envisioned to solve or at least mitigate quality preservation issues of organic materials, originating from moisture interaction under ambient conditions. Liquid phase processing coatings using nano-clay polyvinyl alcohol (PVOH) has been developed reported. Detailed analysis the coating revealed per...

In developing new generations of coatings for medical devices and tissue engineering scaffolds, there is a need for thin coatings that provide controlled sequential release of multiple therapeutics while providing a tunable approach to time dependence and the potential for sequential or staged release. Herein, we demonstrate the ability to develop a self-assembled, polymer-based conformal coati...

Textural features are widespread in many soils, provide pedogenetic evidence, and fundamental soil classification systems. The presence of these their conservation over time require certain processes forming factors. This study investigates the genesis textural pedofeatures, especially clay coatings, stressful conditions that can eventually lead to disappearance. To achieve this goal, four prof...

this study was conducted to investigate the type and origin of clay minerals via several profiles in lordegan hilly lands. the profiles were located in two kinds of land uses including forest and dry farm at different slope positions as sampling sites. the soil saples were collected from two depths of soil horizons to indicate cec, soil texture, oc%, calcium carbonate equivalent, x-ray diffract...
