In this study, we have investigated the contribution of bovine serum albumin (BSA) to the durability of the electrochemically synthesized poly(3,4-ethylenedioxythiophene) (PEDOT) film on a platinum (Pt) electrode. The electrode was capable to effectively adsorb the nano Au particles (AuNPs) to form a uniform layout, which was then able to immobilize the horseradish peroxidase (HRP) to construct...

The adhesion durability of coatings and encapsulant materials utilized in electronic packaging is vital for device reliability in the microelectronics industry. Due to adverse operating conditions such as high moisture and high temperature environments, the adhesion between an adhesive and its substrate is typically compromised. This thesis addresses the advantages of employing plasma pretreatm...

Applications of multi-state approach to the reliability evaluation of systems composed of independent components are considered. The main emphasis is on multi-state systems with degrading components because of the importance of such an approach in safety analysis, assessment and prediction, and analysing the effectiveness of operation processes of real technical systems. The results concerned w...

abstract ion selective electrodes (ises) are electrochemical sensors that respond selectivity to the activity of ionic species. an ion-selective electrode is an electrochemical device that uses a thin selective membrane or film as the recognition element, and is an electrochemical half-cell equivalent to other half-cells of the zeroth (inert metal in a redox electrolyte). in common methods o...

Background and objective: Experience with past earthquakes and numerical analysis confirms that the durability of strong earth motion, significantly can affect the amount of failure of civil engineering systems. However, if the durability is related to a parameter which describes the intensity of the earth's motion, such as maximum velocity or maximum acceleration or spectral acceleration, then...
