Even in the 21st century, water contamination has been a big problem and industrial processes are to be blamed for polluted supplies. The use of sunlight process photocatalysis is an efficient way purify wastewater. Composites TiO2/activated carbon/two-dimensional selenides performed better than either individual material or binary composites this application. A straightforward hydrothermal tec...

To obtain a tensile strain-hardening behavior by using the ordinary polypropylene (PP) fiber, micromechanical model recommends increase of fiber low interfacial bond with an cementitious matrix. It was predicted that alkali-activated slag (AAS) composite high drying shrinkage performance would affect interface frictional during pullout.

This clinical report describes the fabrication and bonding of porcelain laminate veneer restorations in a patient with anterior open spaces. Laminate veneer restorations made of feldspathic porcelain were etched with 5% hydrofluoric acid, rinsed under tap water, ultrasonically cleaned with methanol, and primed with a chemically activated three-liquid silane bonding agent (Clearfil Porcelain Bon...

Composite elastomer microwave absorbers were developed based on two-phase hybrid filler. Nanosized magnetite was synthesized for the first time in porous texture of activated carbon. Combination fillers with high dielectric losses such as active carbon, and magnetic into filler is considered a new Hightech generation specific technical characteristics. The influence obtained shielding effective...

a palladium composite membrane was prepared via electroless plating technique using organic-inorganic method during activation process. the ceramic support surface was modified by two tio2-boehmite and one γ-alumina layers to avoid pd penetration in support pores. thin and defect-free pd composite membrane was obtained by creating a relative smoothness on the ceramic support and using pd nanopa...

In this work, separation performance of supported carbon membranes produced from Novolac Phenolic resin as the main precursor and carbon nanotubes as nanofiller were investigated for separation of CO2 from N2 and CH4. Supports were produced by carbonization of Novolac Phenolic resin-activated carbon mixture, and selective layer was coated by dip coating of prepa...

The adsorption of malachite green from aqueous solution using a local low cost adsorbent, acid activated Ntezi clay, was investigated. The low cost adsorbent was activated with different concentrations of sulphuric acid and the physicochemical properties of the adsorbent were determined and the structural properties were analyzed using XRF and XRD. The adsorption process was studied as a functi...

A composite of modified graphene and LiFePO4 has been developed to improve the speed of charging-discharging and the cycling stability of lithium ion batteries using LiFePO4 as a cathode material. Chemically activated graphene (CA-graphene) has been successfully synthesized via activation by KOH. The as-prepared CA-graphene was mixed with LiFePO4 to prepare the composite. Microscopic observatio...
