Most cellular solids are random materials, while practically all theoretical structure-property relations are tor periodic models. To generate theoretical results for random models the finite element method ( FEM) was used to study the elastic properties of open-cell solids. We have computed the density ( I J ) and microstructure dependence of the Young's modulus ( E ) and Poisson's ratio ( v )...

This paper presents an investigation of ultimate load, maximum deflection and failure mode foamed concrete composite slabs (FCCS). Of interest are the effects dry density slab thickness. Unlike conventional slabs, FCCS has advantage eliminating selfweight penalty thus reducing underlying structural members.With advanced research in technology, with sufficient strength propertiesto meet requirem...

We studied the hygroscopic properties of gelatin from waste-products after processing common fresh-water fish species form Astrakhan region (skin, scales, bones, fins, and cartilage) as an object drying. The analysis thermodynamics internal mass transfer was carried out during interaction substance specified product with water. objects study were concentrates obtained by convective-radiation dr...

In this study, we developed a simple and easy method to use bicarbonate buffer solutions for dissolution tests. A floating lid was newly introduced prevent the evaporation of CO2 from (the method). This used evaluate profiles 5-aminosalicylic acid (5-ASA) colonic delivery tablets with pH-sensitive film coating (5-ASA CDT) (Asacol® 400 mg tablet generic products B). sodium solution added test ve...

Latent Heat Thermal Storage (LHTS) based on Phase Change materials (PCMs) offers a promising solution for efficient utilization of intermittent energy from renewable sources. The primary limitation is the poor thermal conductivity PCMs, which requires employing performance enhancement techniques. To enhance PCM storage, copper foam with high porosity embedded PCM. A numerical simulation model h...

Abstract Lightweight concretes are increasingly being used in the construction industry, either for overall lightweighting of structure itself, reducing material consumption and thus CO 2 emissions, or specific reasons such as improving thermal insulation properties acoustic properties. Today, lightweight with expanded aggregates (expanded clay, agloporite) most commonly used. This paper deals ...

The present study investigates extrusion processing of unfoamed and foamed cocoa butter (CB) crystal-melt suspensions (CMSs) with varying crystal volume fraction ΦSFC. Capillary rheometry derived flow curves were fitted the Herschel–Bulkley–Papanastasiou (HBP) model, yield stress to wall shear ratio τ0/τw CB CMSs was compared for various Foamed behaved fluidlike ΦSFC≤11.9% according a brittle p...

Intercalation of lithium into Ag-CNTs sample is reported here. We have used a nano-porous silver foam as a frame for deposition of the CNTs   inside   the   pores   by   electrophoresis   deposition   (EPD) technique. By using  chronopotentiometry method,  we  have noticed that the Li storage capacity of the prepared Ag-CNTs electrode was improved  noticeably  in  comparison  with  literature. ...
