Investigation on pitting corrosion rate of Micro Plasma Arc Welded Titanium (Ti-6Al-4V) alloy sheets in KBr solution using TOPSIS
Abstract: Titanium is having good anti-corrosion properties in both basic and acidic medium. However, when it is subjected to severer heating processing like welding, there is a possibility of corrosion formation at the weld joint. In the present work Pulsed current MPAW is used for joining 0.5 mm thick Titanium (Ti-6Al-4V) alloy sheets. Peak Current, Base Current, Pulse Rate and Pulse Width are considered as input parameters and fusion zone corrosion …

Built in Self Repair for Embedded Memories: A Survey
Abstract: Memory is a significant part of every single computing system. In SOC (System-on-a-chip), 90 to 92% of the total chip zone is enclosed by embedded memories (ITRS 2009) and that means memory density is higher than the logic density. Consequently testing and diagnosis of memories are imperative issues in the SOCs. Revenue of memory is pretentious by the accountabilities present in memory which also distresses the yield of SOC. Built …

Improving Photocatalytic and Antibacterial Properties of Zein/Polyvinyl Alcohol Polymer Composite Film by Dispersing TiO2 Nano Particles
Abstract: Zein/polyvinyl alcohol/nano-TiO2 composite film was effectively blended using a solution casting method. Mechanical, photocatalytic, and antibacterial properties of the composite film were evaluated. The breaking elongation of the composite film increased up to the maximum loading of 0.4% of nano-TiO2. The humidity and moisture content relationship was estimated with standard modified models of Halsey, Oswin, Chung Pfost, and Henderson. It was found that the Halsey model was the most suitable …

Glass Fiber Layer Effect on Chemico-mechanical Properties of Light Cure Adhesive Systems
Abstract: Introduction: Orthodontic adhesives should have clinically acceptable shear and tensile bond strength to withstand masticatory forces and those generated by treatment mechanics. Mechanical properties of the adhesive, such as flexural modulus of elasticity, tensile strength, and compressive strength, are more heavily influenced by the resin matrix's Degree of cure (DC). Aim: The study compares the effect of the Glass fiber layer on Chemico-mechanical properties using three different light cure adhesive …

Application of Aqueous Two-Phase Systems in the Extraction of Bovine Serum Albumin
Abstract: Protein partitioning in an aqueous two-phase system (ATPS) has been found to be a powerful method for extracting and separating mixtures of biomolecules. In ATPS, many factors influence the partition coefficient K (which is the ratio of protein concentration in the top phase to that in the bottom phase) and the recovery percent (Rec%). Two systems of ATPS were used: first, polyethylene glycol (PEG4000)/sodium phosphate, and second, PEG4000/dextran. The behavior …
