A review of the electrical properties, performance and physical mechanisms of the main silicon-on-insulator (SOI) materials and devices. Particular attention is paid to the reliability of SOI structures operating in harsh conditions. AkzoNobel’s International brand has launched a thin-film, spray-applied insulation coating for industrial environments. AkzoNobel Intertherm is a spray-applied insulation coating for industrial environments that can bring hot surfaces down to safe-touch temperatures, AkzoNobel says.
Recently, two-dimensional (2-D) layered transition metal dichalcogenides such as molybdenum disulfide (MoS 2) have drawn great interests as a promising channel material of thin-film transistors (TFTs) for high-performance transparent and flexible electronics. 1–7 1. H. Y. Chang, S. Yang, J. Lee, L. Tao, W. S. Hwang, D. Jena, N. Lu, and D. Akinwande, ACS Nano 7, (). Membrane‐based desalination is the fastest growing technology in the area of desalination. Reverse osmosis (RO) and nanofiltration (NF) have been established in the last couple of decades; meanwhile, forward osmosis (FO) has begun to find its own place in the field of desalination. Typical commercial polyamide (PA) thin film composite (TFC) membrane has been mostly used in .

Here, the multilayered YSZ/Al 2 O 3 thin film as insulating layer was deposited by reactive sputtering. The prepared multilayered film exhibited improved insulation property as compared to the single Al 2 O 3 thin film, the insulation resistance of the four-layered YSZ/Al 2 O 3 /YSZ/Al 2 O 3 film increased roughly two orders of magnitude.

The pollution design of insulation applied in desert environments has traditionally been based largely on IEC guidelines that recommended a USCD of mm/kV for AC systems in heavily contaminated areas.
It became increasingly evident over the years, however, that these guidelines were often not suitable for extreme desert and desert/coastal. Kyocera ECU substrates provide high density circuit design, high temperature durability, good heat dissipation and high reliability with multilayer ceramics.
HTCC (High Temperature Co-fired Ceramics, alumina system), and LTCC (Low Temperature Co-fired Ceramics, glass ceramic system) are available. Printed resistors and high-current-capacity 'Trough' conductive line structures are also available.
High Reliability Harsh Environment Electronics. Performance challenges at high temp: •Parameter shifts over temperature and time •Integration potential. Reliability challenges at high temp: •Industry driven by O&G: 1 -2K hours of life at C •Long Un-accelerated testing time (Years!).
