DC voltages via spin rectification effect (SRE), VDC, under microwave irradiation are investigated for three platinum (Pt)/ferromagnetic metal (FM) bilayer structures: Pt/Ni80Fe20, Pt/Co, and Pt/Fe. At the frequency region lower than resonant frequency, large VDC is obtained at zero magnetic field all devices. In dependence just around sharp rise drop of magnitude in observed. These behaviors w...

the silica supported platinum nanoparticles was synthesized by using the sol-gel method. the possibility of using diamminedinitro platinum (ii) as pt precursor and effect of metal precursor concentration on the final pt nanoparticle size was investigated. a stable silica sol was prepared via hydrolysis of tetraethyl orthosilicate (teos) as a metal alcoxide and condensation reaction. subsequentl...

Platinum is a metallic element, which may react with our cellular component through its involvement in cancer chemotherapy medications. Cisplatin is one of the most useful antineoplastic drugs against human ovarian carcinoma, which has the central element of platinum in its structure. The nature of chemical interaction between platinum and cellular macromolecules is yet to be understood. We exa...

Theoretical analysis and Computer simulations have proven to be cost-effective and powerful tools in scientific studies of materials, particularly at nano-scale where synthesis of nano-structures, interpretation of their observed character and exploration of new structures are not always straight forward. We present here fundamental principles of techniques used today for computational simulati...

A low pressure plasma process based on plasma deposition has been used to develop a drug delivery strategy. In this study, a drug delivery system based on different layers of plasma co-polymerized Poly ε-caprolactone-Polyethylene glycol (PCL-PEG) co-polymers was deposited on biocompatible substrates. Cis-platinum (118 μgm/cm2) was used as an anti-cancer drug and incorporated for local delivery ...

The present work describes a new approach to directly electrodeposit platinum nanoparticles on the surface of multi-walled carbon nanotubes (MWNTs) through cyclic potential scanning technique and to prepare a novel carbon nanotubes including platinum nanoparticles modified electrode (noted as Pt/MWNTs). TEM image shows that Pt nanoparticles are attached on the out surface of the MWNTs with aver...

Direct alcohol fuel cells (DAFCs) are a type of electrochemical energy conversion device that directly Convert the chemical energy stored in a liquid alcohol fuel, commonly methanol and ethanol, and also ethylene glycol, or npropanol, to electricity. Because of their simplicity, high energy density, instantaneous recharging, and presumably long life, DAFCs have been identified as the most promi...

This paper presents a comparative study of titanium (Ti), platinum (Pt), and nitride (TiN) micro-electro mechanical systems based micro-heaters. In the present study, common geometry thin film thicknesses were selected to achieve comparable base resistances for all three microheater materials. Titanium, platinum, films are deposited using DC magnetron sputtering, E-beam evaporation, reactive sp...

Manipulation and control of matter at the nanoand atomic level are crucial for the success of nano-scale sensors and actuators. The ability to control and synthesize multilayer composite structures using carbon nanotubes that will enable to build electronic devices within a nanotube is still in its infancy. In this paper, we present results on selective electrochemical deposition of metals and ...
