Abstract With the development of soft gripper systems, food processing, packaging, and processing technology has seen a significant advancement. The must be protected from surface contamination liquid lubrication; hence, hydrophobic contamination-resistant is used. There an urgent need for that meets functions performance resistance, but there been little study. In this study, two are well achi...
Despite the use of transition metal dichalcogenides being widespread in various applications, knowledge and applications MoxW1−xS2 compounds are relatively limited. In this study, we deposited a MoW alloy on Si substrate using sputter system. Consequently, successfully utilized furnace to sulfurize from 800 950 °C, which transferred into ternary compound. The Raman spectra samples indicated an ...
Heat at the junction of light-emitting diodes (LED) affects the overall performance of the LED in terms of light output, spectrum, and life. Usually it is difficult to measure junction temperature of a LED directly. There are several techniques for estimating LED junction temperature. One-dimensional heat transfer analysis is one of the most popular methods for estimating the junction temperatu...
Zero temperature coefficient of resistance (TCR) is essential for the precise control of temperature in heating element and sensor applications. Many studies have focused on developing zero-TCR systems with inorganic compounds; however, very few have dealt with developing zero-TCR systems with polymeric materials. Composite systems with a polymer matrix and a conducting filler show either a neg...
