Effect of Hafnium on Nickel-Titanium based Thin Film Coating by DC/RF Magnetron Sputtering Technique
Abstract: Ni-Ti-Hf films as shape memory alloys were successfully prepared by magnetron sputtering technique using individual Ti, Ni and Hf targets. The hafnium content was varied from 6% to 30% and the required film composition was achieved by adjusting the power ratio to the targets. The as-deposited films were amorphous; a post deposition annealing was performed at 700 °C to crystallize the Ni-Ti-Hf films. Structural, compositional and phase-transformation studies were carried …

Statistical Analysis of Geomagnetic Activity and Solar Activity Features during Solar Cycle 23 & 24
Abstract: We present a statistical analysis of the geomagnetic storm (GMSs) with the solar activity features (Sunspot number (SN), H-α flare and coronal mass ejection (CME)) during solar cycle 23 and 24. Sunspot number (SN) shows good correlation with peak values of GMSs indices (correlations coefficient R= 0.76) while CME(R=0.59) and H-α (R=0.55) show moderate correlation. So we conclude that GMSs have good correlation with solar activity features during major geomagnetic …

Liquid Crystals as Novel Drug Carrier: A Review
Abstract: Liquid crystal is a thermodynamic stable phase characterized by anisotropic properties, generally lying in the temperature range between the solid and isotropic liquid phase, hence are termed mesophase. Based on the way that liquid crystals are obtained, they can be classified into two types—thermotropic liquid crystals and lyotropic liquid crystals. The thermotropic liquid crystal is generated by variation of temperature in the liquid state, while the lyotropic liquid crystal is …

Role of ion Regulation in Heartbeat Initiation
Abstract: The heart can beat quite 2 billion times in normal life, but the mechanism by which the guts beats is that the subject of intense research. Since the invention of pacemaker currents in 1978, several studies have shown that rhythmic changes in membrane tension (the "membrane tension clock") underlie the mechanism of automation. It's the depolarizing current activated during hyperpolarization. Therefore, when the guts cells recover, it's activated, the cell …

Effect of Initial Temperature and Diameter of Ethanol Droplet on Evaporation Dynamics in Convective Air Medium
Abstract: Ethanol is a suitable biofuel as it has fewer toxic emissions and higher-octane numbers. For spray combustion applications, the gas phase motion must be considered while numerically investigating the fundamental aspects of droplet evaporation and combustion processes. Hence, we have numerically simulated the evaporation dynamics of an isolated spherically shaped ethanol droplet under a forced convective air environment in the absence of gravity. The momentum transfer between two phases is …

Distinctive Approaches for Improving the Aqueous Solubility of BCS Class II Drugs
Abstract: The most difficult feature of many novel chemical entities is their solubility behaviour, as 60 percent of new promising products suffer solubility limitations. This is the most common reason for novel medicine compounds failing to reach the market or performing to their full potential. The proportion of the aqueous phase when the solution is in equilibrium with the pure substance in its normal phase is referred to as aqueous solubility. …

The Role of Cholesterol in Biological Membranes
Abstract: Cholesterol plays the role of a regulator that ensures the correct packaging of the lipid part of the membrane, which is necessary for its normal operation, by influencing on the mobility of the fatty acid tails of membrane lipids: if the membrane is too rigid and there is a danger of "freezing" of fatty acid chains, cholesterol causes it to liquefy, since the chains in its presence become more mobile; …
