This study has been carried out to optimise the silver (Ag) content of the coating synthesised on commercially pure titanium (Cp-Ti, Grade 4) for biomedical applications by micro-arc oxidation (MAO) process. The MAO process has been conducted in electrolytes containing silver acetate (AgC2H3O2) at different concentrations between 0 and 0.002 mol L-1. When compared to the base electrolyte, coatings synthesised in >= 0.001 mol L-1 AgC2H3O2 added electrolytes exhibited an antibacterial efficiency of 99.8% agai...
Optimisation of spray drying parameters for Lactobacillus acidophilus encapsulation in whey and gum Arabic: Its application in yoghurt

To maintain viable cells over the critical value of 10(6) cfu g(-1) throughout shelf life of probiotic yoghurt, Lactobacillus acidophilus LA-5 was encapsulated by spray drying using whey powder (WP) and gum arabic (GA) mixtures. Box-Behnken Design (BBD) method was used to optimise drying conditions and WP to GA ratio in wall material. Responses were recorded for encapsulation efficiency and production efficiency of microcapsules. Optimum conditions were determined as: inlet air temperature, 140 degrees C; l...
Optimizing heat exchanger parameters of a joulethomson cryogenic cooler to improve the cooling performance
Baki, Murat; Okutucu Özyurt, Hanife Tuba; Sert, Cüneyt; Department of Mechanical Engineering (2018)
Cryocoolers are one of the key components of cooled infrared (IR) imaging systems, where it is not possible to form an image in photon detectors without decreasing the sensor temperature to cryogenic temperatures. In detector cooling applications where low cool down times, small size and weight are required, mostly Joule Thomson (JT) cryocoolers are preferred. The aim of this study is to analyze the heat exchanger of a JT cryocooler operating with argon as the working gas, numerically and optimize its desig...
Optimized spacer layer thickness for plasmonic-induced enhancement of photocurrent in a-Si:H
Saleh, Z. M.; NASSER, H; ÖZKOL, E; GÜNÖVEN, M; Abak, Musa Kurtuluş; Canlı, Sedat; Bek, Alpan; Turan, Raşit (2015-10-24)
Plasmonic interfaces consisting of silver nanoparticles of different sizes (50-100 nm) have been processed by the self-assembled dewetting technique and integrated to hydrogenated amorphous silicon (a-Si:H) using SiNx spacer layers to investigate the dependence of optical trapping enhancement on spacer layer thickness through the enhancements in photocurrent. Samples illuminated from the a-Si:H side exhibit a localized surface plasmon resonance (LSPR) that is red-shifted with the increasing particle size an...
Optimizing Mesenchymal Stem Cell Wound Healing Properties on Electrospun Silk with Selenium Nanoparticles
Chung, Stanley; Stolzoff, Mıchelle; Tran, Phong; Ercan, Batur; Webster, Thomas (2015-12-31)
Statement of Purpose: Current treatments for skin wound healing provide limited healing and do not promote skin repair. Therefore, an alternative approach that actively participates in the endogenous wound healing process would significantly improve wound healing and expand the scope of skin treatment to more serious conditions, such as severe burns and epidermal replacement. In addition to their stemness properties, mesenchymal stem cells (MSCs) have a number of cell signaling properties that are very bene...
