A palladium composite membrane was prepared by electroless plating on oxidized porous stainless steel support (ox-PSS). Hydrogen permeation flux through this composite membrane was measured in the temperature range of 574-674K and the pressure difference of two sides of membrane up to 90kPa. A simplified resistance model was employed to analyze the permeation behavior of hydrogen through Pd/ox-...

A new approach for sensing bioanalytes utilizing unmodified noble metal nanoparticles to fabricate a colorimetric sensor array is described. In this array, a series of gold and silver nanoparticles with various sizes whose color change based on the interactions of bioanalytes and nanoparticles, provide the unique response patterns for bioanalytes such as protein and bacteria which can be distin...

A novel organic polymer composite for the encapsulation of metal catalysts and applications to synthesis are described here.

We investigate the frustrated magnetic interactions in cubic transition metal oxides with orbital degeneracy. The eg orbitals order easier and their ordering explains the A-type antiferromagnetic phase in KCuF3 and LaMnO3. In t2g systems the magnetic order changes at a transition from an orbital liquid to orbital ordered states. The fluctuations of t2g orbitals play a prominent role in LaVO3 an...

Alginate-metal complexes were prepared with divalent (Ca, Ba, Zn) and trivalent metals (Fe, Al) via congealing method in form of beads. Alginate mixed metals (Ca & Fe) complexes were also prepared by simultaneous and consecutive congealing. The studied beads were blank beads and racemic ketoprofen (KTP) loaded beads. Metal content was determined by atomic absorption spectroscopy and was 1.8% to...

The interaction of surface acoustic waves with conduction electrons island films various metals was investigated. Island were formed on the piezoelectric crystalline substrates: Lithium Niobate, Bismuth Germanate, and Piezoquartz. It is experimentally obtained that wave attenuation as a function film resistance has characteristic maximum, velocity changes from at free substrate to metallized su...

Mixed crystals can be categorized as the crystal in which two or more different types of atoms are present and configured. These atoms interact each other in the influence of Coulomb force of attraction and the presence of short range repulsion force. Due to this interaction they tends to be arranged in equilibrium state and forms new material. A pure crystal can be doped by impurities with pro...
