Sputtering pressure effects and temperature-dependent magnetism of Co/Pd multilayers" (1994). David Sellmyer Publications. Paper 102. The temperature dependence of the sputtering Ar pressure effects on magnetic properties and the coercivity mechanism of Co(2 &/Pd(13 A) multilayers were studied as the sputtering Ar pressure varied from 3-15 mTorr and the temperature from 300 to 35 K. It is found...

A nanofluid is mixture of nano sized particles and a base fluid. This paper investigates by using laboratory based double pipe heat exchanger model, the performance of nanofluid containing about 48.46nm  particle size nanoparticles (ZnO) without or with addition of nonionic surfactant Rokanol K7 (500ppm) into the base fluid double distilled water to prepared three different concentrations 1.0%,...

Abstract Wet heatwaves can have more impact on human health than hot dry heatwaves. However, changes in these received little scientific attention. Using the ECMWF Reanalysis v5 reanalysis dataset, wet-bulb temperatures ( T w ) were used to investigate spatial-temporal variation of wet Eurasia for 1979–2017. defined as three day or longer periods when was above 90th percentile summer distributi...

Strong dependence of the crystal orientation, morphology, and melting temperature (Tm) on the substrate is observed in the semicrystalline polyethylene thin films. The Tm decreases with the film thickness decrease when the film is thinner than a certain critical thickness, and the magnitude of the depression increases with increasing surface interaction. We attribute the large Tm depression to ...

The voltage (V) and frequency (f) dependence of dielectric characteristics such as dielectric constant (e0), dielectric loss (e00), dielectric loss tangent (tan d) and real and imaginary part of electrical modulus (V0 and M) of the (Ni/Au)/GaN/Al0.3Ga0.7N heterostructures have been investigated by using experimental admittance spectroscopy (capacitance–voltage (C–V) and conductance–voltage (G/w...
