This paper focuses enhancement of the electrical insulation properties commercial polycarbonate using nanostructured alumina as an additive material.Various composites have been prepared by varying level material and DC conductivity in presence oxygen derived composite materials has measured which activation energy (Ea) profiles evaluated.Results show that incorporation significantly reduces Ea for composites, compared to base material.Further, decrease is found be dependent on body.As...
Abstract Conjugated polymers are excellent barriers for membrane separations because their porosity can be controlled at the molecular level through chemical doping. Polyaniline (PANI) is particularly attractive simple acid/base doping/undoping enables a controllable of doping that readily achieved using dopants different sizes and shapes. PANI, which belongs to an important member family electrically conducting polymers, has been studied extensively as due its distinct electrochemical...
In this work, a titanium-doped hydroxyapatite (HAp) scaffold was produced from two different sources (natural eggshell and laboratory-grade reagents) to compare the efficacy of natural synthetic resources HAp materials on new bone regeneration. This comparative study also reports effect Ti doping physical, mechanical, in vitro as well vivo biological properties scaffold. Pellets were prepared conventional powder metallurgy route, compacted, sintered at 900 °C, showing sufficient porosity for...
In the quest for finding sustainable energy harvesting solutions, field of high-temperature stable flexible piezoelectric harvesters is emerging as an exciting area research. present research, approach has been taken to enhance Curie temperature poly(vinylidene fluoride) (PVDF) by blending it with a poly(ether imide) (PEI) polymer. A polymeric solution PVDF in N-methyl-2-pyrrolidone (NMP) prepared at fixed concentration 10 wt % and mixed different percentages (5, 10, 15% on weight pellets)...
The alumina grains in liquid‐phase‐sintered (LPS) materials prepared from different commercial sources have a predominantly platelet morphology. Generally, the MgO:(CaO + BaO Na 2 O K O) ratio chemical composition controls morphology LPS that is 91–94 wt% pure. Within given range of SiO content (i.e., 4.3–5.2 composition), low <1.0) compositions favors formation elongated grains, whereas ratios >1.0 result equiaxed grains. contents outside favor A tendency to form platelike observed...

Biodegradable composite biomaterials play a pivotal role in the healthcare and addressing many challenging issues. Present study reports on synthesis characterization of hydroxyapatite (HAP) gelatine-PVA composite, analyses incorporation HAP investigating their biocompatibility mechanical properties. The material was prepared film form by mixing freshly into solution finally drying them to make film. Composite were characterized scanning electron microscopy (SEM), X-ray diffractometry (XRD),...
Abstract This work highlights the recovery of water from sewage effluents using alumina ceramic membranes with pore sizes 0.2 and 0.45 µm respectively in dead‐end filtration mode. The demonstrates ability advantages alumina‐based microfiltration (MF) filtering microbes other harmful pollutants normally present fouling behavior cycle is identified, which turn helped to regenerate fouled for subsequent usage. Regeneration studies also suggest that though chemical cleaning was effective...

Despite availability plethora nanoparticle processes, there exist difficulties controlling shape, size, purity nanoparticles quantities safe cost‐effective manner. have been...
Abstract One of the possible approaches to remove Pseudomonas bacteria from surface water by using textile fibrous media has been studied in this article. The attachment inside was laboratory column experiment which led understanding physiochemical interaction between and bacteria. Colloid‐filtration theory used investigate effects various physicochemical factors like pH, ionic strength (M) mass (g) porous on bacterial attachment. quantitative assessment carried out determining collision...
A mechanism to remove the Pseudomonas bacteria from contaminated water by using textile fibrous media has been proposed in this article. The attachment of on different material was studied laboratory column experiment. Two types textiles made polyester and nylon fibers were selected for experimental design included various level salt concentration calcium chloride (i.e. 1 mM, 50 100 150 mM). maximum removal efficiency is 77% that 58.33% same ionic strength. colloidal filtration...
A solution combustion technique for the synthesis of different β‐alumina compositions in Na 2 O· x Al O 3 system (where =5, 6, or 7) is described along with structural characterization materials prepared.
