Natural radioactivity is responsible for most of the total radiation dose received by human population. Geological materials used in building industry usually become contaminated with naturally occurring radioactive materials. They are used as mixtures in building industry (kaolin, zircon, frit, feldspar) or mechanically processed and used for covering floors and walls of the rooms (granite). I...

The study aimed to evaluate the yield components and physiological quality of rice seeds produced, obtained from coated with rusk ash kaolin®. Treatments consisted coating two sources silicon (silicate aluminum-70% SiO2 (kaolin® husk ash- 95% SiO2) at doses 0; 30; 60; 90 120 g.100 kg-1 seed. Yield were evaluated: Seed per plant, number panicles plant plant. subjected germination, first ...

the studies report the synthesis of novel graft copolymer of oatmeal. polymethyl methacrylate grafting was carried out on oatmeal backbone via ‘microwave assisted’ approach. the graft copolymers were optimized by varying monomer and can concentration. the synthesized graft copolymers were characterized by intrinsic viscosity, ftir, tga, sem, elemental analysis, number average molecular weight a...

In the present investigation, we compared reduction in attachment ability of southern green stinkbug Nezara viridula (Hemiptera: Pentatomidae) to glass induced by three different nanoparticle (kaolin, zeolite, and calcium carbonate) films. Using traction force experiments, behavioral scanning electron microscopy observations, analyzed insect linear speed on untreated treated with particle The n...

Kaolin-SO3H nanoparticles were prepared via reaction of kaolin and chlorosulfonic acid and characterized by FT-IR, XRD, FESEM, TEM, XRF, EDS, BET and TGA. The activity of this green catalyst was probed by the synthesis of aryl diazonium salts as the starting reactant and then, their diazo coupling with  2-naphthol to form azo dyes in a solvent-free medium at room temperature...

Field-grown grapevines are often exposed to multiple environmental stresses, which challenges wine-growers develop sustainable measures sustain vine growth, yield, and quality. Under field conditions this task is demanding, due differences in the magnitudes of stresses associated plant responses. In study we explored hypothesis that kaolin-particle film application improves grapevine photoprote...

Sodium titanate nanobelt was synthesized by treating titanium dioxide hydrothermally in concentrated sodium hydroxide solution. The product was characterized by SEM analysis and zeta potential measurements. It served as a microparticle to constitute a microparticle retention system with cationic polyacrylamide (CPAM), while the microparticle system was employed to induce the flocculation of kao...

A slow-release fertilizer is important to improve soil conditions and enhances food security through continuous plant supply. With urea as a nitrogen source, kaolin carrier, acrylic acid reaction monomer, potassium persulfate an initiator, N, N '- methylene bisacrylamide crosslinking agent, under the action of cyclohexane sorbitan monostearate, based was synthesized by reverse suspension method...

Abstract The present study provides a complete perspective of recyclable molybdovanadophosphoric acid immobilized on kaolin (MVPA/Kaolin), hybrid material for catalytic degradation the dye, Chromotrope 2R in water under mild reaction conditions. Novel MVPA/Kaolin was synthesized with an advanced impregnation method. characterized PXRD, FTIR, ICP-OES, SEM–EDX, TEM, TGA, surface area, porosity, a...

Abstract A correlation effect between particle size of kaolin clay and injection moulding process parameters on impact strength, shrinkage warpage high-density polyethylene/kaolin (HDPE/KC) composites was carried out using analysis variance (ANOVA). Kaolin with sizes < 75, 75–106 106–150 μm used. The that were taken into consideration temperature, packing pressure time. In general, experimen...
