Thin Pd–40%Cu films were obtained via the classical melting and rolling method, magnetron sputtering, modified with nanostructured functional coatings to intensify process of hydrogen transportation. The by electrodeposition, according method obtaining palladium black “Pd–Au nanoflowers” spherical pentagonal particles, respectively. experiment results demonstrated highest catalytic activity (89...

A voltammetric electronic tongue consisting of a composite metal base electrode array for discrimination of basic taste has been presented. The electrode array consisting of Gold, Nickel, Palladium, Copper and Glassy Carbon as working electrode, has been used for transforming information of taste substances into electric signal. The electrodes output show different patterns for chemical substan...

The formation of Pd(0) in the absence of any classical reducing agent in a medium containing Mg(2+)/Al(3+) layered double hydroxide (LDH) and N,N-dimethylformamide was evidenced. XRD analysis showed the presence of crystalline phases of palladium in the Pd/LDH composite. Suzuki-Miyaura reactions in aqueous medium were carried out at room temperature, and good yields were obtained with bromoaren...

Poly (amide-6-b-ethylene oxide)/Zinc Oxide (PEBA/ZnO) mixed matrix membranes were fabricated using ethanol/water as solvent by solvent casting method. The concentration of ZnO in membrane was set to 0.1 wt.% and the synthesized membranes were characterized by AFM and FTIR. Effects of ZnO nanoparticle on CO2, CH4 and N2 permeabilities, and CO2/N2<...

STATEMENT OF PROBLEM Ceramics are widely used for anterior restorations; however, clinical color reproduction still constitutes a challenge particularly when the ceramic crowns are used on titanium implant abutments. PURPOSE The purpose of this in vitro study was to investigate the effect of implant abutment material on the color of different ceramic material systems. MATERIAL AND METHODS F...

objective(s) in this study, a kind of ph sensitive composite membrane was prepared and drug permeation through it was investigated in terms of ph. rationale of this study originated from the fact that a ph change which may be a result of a disease state in the body can trigger drug release. materials and methods  here, a kind of ph sensitive composite membrane containing different nanoparticle ...
