Electrochemical impedance spectroscopy (EIS) was used to study the corrosion behavior of electroless nickel immersion gold processing printed circuit bar drain board boards (PCB-ENIG) in a simulated electrolyte solution (0.1 mol.L-1 NaHSO3), and the morphology, composition of corrosion products as well as the failure mechanism of the plating layer

The purpose of this paper consists in the evaluation of the contact angle at the interface of Co-Cr sintered samples by DMLS process.The sintered samples supported a post treatment and were coated by HA using att nighthawk hotspot sol-gel method and were immersed in simulated biological fluid SBFx1 for 7 days.The Co-Cr (ST2724G) sintered disks by D

t present complex conditions, systems of education and particular system of higher education gradually find that they will not be able to response their increasing leadership responsibilities without using effective management, because by appearing significance of higher education in the society, people are sensitive toward its relative problems da

This study is concerned with two things: To explore the extent to which certain aspects of the practicum students orientation may read more be changed in the process of actual working experience and secondly to explore the possible influence of the students working experience in future profession.An questionnaire was used on a sample of fifty libra

Abstract Chronic wounds are often infected with biofilm bacteria and characterized by high oxidative stress.Current dressings that promote chronic wound healing either require additional processes such as photothermal irradiation or leave behind gross amounts of undesirable residues.We report a dual-functionality hydrogel dressing with intrinsic an
