To enhance the efficiency of heat transfer fluids, encapsulated phase change materials (PCMs) have been researched as media for storing and release a latent heat. The thermal energy transportation durability PCM capsules are quite dependent on physicochemical mechanical properties their shell. Herein, we prepared poly(2-hydroxyethyl methacrylate) (pHEMA) paraffin-wax sphere capsule with high encapsulation ratio, efficiency, storage capability 97.67, 97.33, 99.65%, respectively. A hydrous...
This work examined the influence of dual incorporation MoO2 and SiO2 on corrosion behavior pure titanium treated via plasma electrolytic oxidation (PEO). To achieve this purpose, substrate was PEO in an alkaline-molybdate electrolyte without with nanoparticles. The microstructural observation revealed that addition nanoparticles into during helped to seal structural defects coating so a rougher, thicker, denser rich successfully obtained. From electrochemical measurements 3.5 wt.% NaCl...
Abstract High‐entropy alloys (HEAs), which are near‐equimolar of four or more metal elements, have long been used to achieve the desired properties catalytic materials. However, a novel alloying approach that includes multiple principal elements at high concentrations generate HEAs as materials has reported. The fabrication well‐defined ultrastable supported HEAs, provide superior performance and stability catalysts owing their augmented entropy lower Gibbs free energy, remains critical...
We have been searching a new ion exchange material in the form of fiber which could get large advantages over conventional bead type. In this approach, an effective chelating is prepared by coupling polyacrylonitrile (PAN) and ethylenediamine. A synthesized (poly(acrylo-amidino ethylene amine), PAEA) achieved 7.8 mequiv/g adsorption capacity batch test. The process were confirmed through FT-IR, acid−base neutralization titration, ICP, IC, AAS. By means verifying bonding peaks (hydrogen ionic...
A facile strategy is successfully developed for the centimeter-scale preparation of hierarchically porous aminosilica monolith as a CO2 adsorbent just by simple processes solvent-evaporation-induced coating, self-assembly, and concentration tetraethyl orthosilicate sol on surface polymer foam template without any adhesive composite material or hydrothermal treatment. (3-Aminopropyl) trimethoxysilane immobilized silica via gas-phase procedure. The frameworks mimic those at macroscale, are...
Herein, the effect of degree deacetylation (DD) on gelation chitosan dispersed suspension as an electrorheological (ER) fluid under electric field is presented. The fluids were prepared by dispersing chitin and particles having various DDs into silicone oil, they evaluated fields. alignment in was also observed using optical microscope field. formed fibrous structure between electrodes are though to continue viscosity increase, because attempt move one electrode relative order would be...
