ginger waste material (gwm) has been utilized as adsorbent for removal of hazardouspatent blue vf (pbvf) dye from aqueous solution. batch adsorption experiments wereperformed as a function of ph, contact time, dye concentration, adsorbent dose and temperature.the optimum ph required for the maximum adsorption was found to be 2. the experimentalequilibrium adsorption data were tested using langm...

Herein we demonstrate how the volatility of a liquid can be manipulated by enclosing microdroplets of the liquid into thin polymeric shells. In this way, composite core-shell microparticles consisting of 80 wt% of a liquid core material and 20 wt% of a polymer can be made 150 °C more stable than the individual core component. The thermal stability of the composite microparticles is found to be ...

Crystal violet (CV) was removed from aqueous solutions using walnut shell (WS) as an adsorbent. The effect of initial ph, contact time, adsorbent level and temperature on CV adsorption, were studied in batch mode. The results indicated that both the Langmuir and the Freundlich equations effectively described the adsorption equilibrium. A pseudo second-order kinetics provided a perfect fit for t...

The thermomechanical buckling of simply supported thin shallow spherical shells made of functionally graded material is presented in this paper. A metal-ceramic functionally graded shell with a power law distribution for volume fraction is considered, where its properties vary gradually through the shell thickness direction from pure metal on the inner surface to pure ceramic on the outer surfa...

For the additive manufacturing of chromium-oxide coated stainless steel powders, melting, diffusion, sintering behaviors cementite phase in during heat treatment can affect products’ physical and chemical properties, thus, are worth studying. In this work, we use ReaxFF reactive force-field-based molecular dynamics simulations to investigate at level through an atomistic-scale representation fo...

the aim of this study was to investigate the congo red sorption on soil from the region of iasi (ne of romania). the effects of contact time, temperature, sorbent dose and initial dye concentration on soi sorption were investigated. the results show that the amount adsorbed of congo red on soil increase with increasing dye concentration, temperature and contact time. the experimental data were ...

the purpose of the present study was to develop glipizide controlled release nanoparticles using alginate and chitosan thorough ionotropic controlled gelation method. glipizide is a frequently prescribed second generation sulfonylurea which lowers the blood glucose in type-two diabetics. quick absorption of the drug from the gastrointestinal tract along with short half- life of elimination make...

In the present work, study of the vibration of a functionally graded (FG) cylindrical shell made up of stainless steel, zirconia, and nickel is presented. Free vibration analysis is presented for FG cylindrical shells with simply supported-simply supported and clamped–clamped boundary condition based on temperature independent material properties. The equations of motion are derived by Hamilton...
