we explore electro-catalytic properties of a system consisting of platinum and palladium nanoparticles dispersed over a nanotubular self-organized tio2 matrix. these electrodes prepared by electroess and microemulsion of palladium and palladium nanoparticles on to tio2 nanotubes, respectively. titanium oxide nanotubes were fabricated by anodizing titanium foil in ethylene glycol (eg) fluoride-c...

ELECTROENCEPHALOGRAPHY, as an aid to diagnosis in clinical neurology, has beeni in operation for the past twelve years or more. Hans Berger's classical researches in the electrical potentials of the human brain recorded from the scalp were published between 1929-1937. This work received little attention, probably for the reason that it was published in psychiatric journals which are not as a ru...

A new multipurpose flow-directed pulmonary arterial catheter has been developed and evaluated in 30 patients with acute cardiopulmonary dysfunction. The catheter permits monitoring of the bipolar atrial electrogram, pulmonary arterial or wedge pressure, central venous pressure, and cardiac output, plus atrial pacing. The standard Swan-Ganz thermistor-equipped catheter was modified to incorporat...

nowadays use of detergents and cleaners becomes one of the essential of human life's. since these materials enter to the sewage systems, due to the existing poly phosphate, reacts with water and gradually becomes into phosphate ions and cause too many environmental problems that always have considered environmentalists. this study examined three factors was investigated in the removal of p...

Understanding electron transport across π-π-stacked systems will help to answer fundamental questions about biochemical redox processes and benefit the design of new materials and molecular devices. Herein we employed the STM break-junction technique to measure the single-molecule conductance of multiple π-π-stacked aromatic rings. We studied electron transport through up to four stacked benzen...

This paper reports a multilayered, automated PDMS based microTAS for rapid, high-sensitivity and point-of-care insulin detection. Two generations of microTAS differing in their design complexity and insulin detection protocol were compared. The first generation microTAS includes one micropump, one micromixer and interdigitated electrodes to perform flow through impedance spectroscopy for insuli...
