Cold chain transportation is currently a hot research topic. Since the traditional refrigeration methods lead to consumption of large amounts energy, search for new energy storage materials major trend. In present contribution, n-dodecane/PMMA microencapsulated phase change were prepared by suspension polymerization ice-temperature cold and their preparation parameters explored using encapsulat...

In this research thin film heterogeneous cation exchange membrane was prepared by interfacial polymerization of polyacrylic acid-co-iron nickel oxide nanoparticle son PVC based substrate. Spectra analysis confirmed graft polymerization conclusively. The SEM images showed that polymerized layer covers the membranes by simple gel network entanglement. Results exhibited that membrane water content...

The process of inorganic and organic components temperature transformation metal waste into solid gaseous products in a continuous hot briquetting muffle furnace has been studied. composition the hydrocarbon atmosphere formed under conditions limited access to oxidizer determined. It is shown that thermal destruction coolant oil phase proceeds according complex mechanism consecutive reactions, ...

ethylene was polymerized in slurry phase over a ticl4/mg(oc2h5)2 catalyst activated by al(c2h5)3. it was shown experimentally that mass transfer resistance has no effect on polymerization kinetics. after estimation ofthe active site concentration by inhibition method with carbon monoxide, the effects of polymerization temperature, monomer and cocatalyst  oncentrations and hydrogen were investig...

Background and Aim: Minimizing the polymerization shrinkage of composite resins is a critical goals in composite restorations. Many factors affect polymerization shrinkage. This study aimed to evaluate the effect of composite resin shade on polymerization shrinkage. Materials and Methods: In this in vitro study, 14 composite discs measuring 1.5×8 mm were fabricated. The samples were prepared u...

Abstract Novel hypercrosslinked polymers nanoparticles (HCPNs) were designed by suspension polymerization technique with high surface area as well HCPNs functional groups have the affinity to removal of copper ions from aqueous solutions. Two synthesized through a two-step reaction, initially including N-methacryloxytetrachlorophthalimide (NMTPA) divinyl benzene (DVB) give poly(NMTPA-co-DVB) an...

Polystyrene grafted halloysite microspheres (MS@PMHNTs) were prepared by suspension polymerization method, and the MS@PMHNTs reinforced polymethyl methacrylate (PMMA) composite fibers in situ microfibrillation via a twin-screw extruder. The structure mechanical properties of MS@PMHNTs/PMMA characterized scanning electron microscopy, transmission Fourier transform infrared spectroscopy , thermog...
