Recent electrical insulating varnishes

Electrical conduction in annealed semi-insulating InP

Electrical conductivity of insulating polymer nanoscale layers: environmental effects.

As electronic devices are scaled down to submicron sizes, it has become critical to obtain uniform and robust insulating nanoscale polymer films. For that reason, we address the electrical properties of grafted polymer layers made of poly(glycidyl methacrylate), polyacrylic acid, poly(2-vinylpyridine), and polystyrene with thicknesses of 10-20 nm. It was found that layers insulating under norma...

Electrical Control of Quantum Coherent Phenomena in Insulating Antiferromagnets

Electrical breakdown of insulating ceramics in a high-radiation field

This report addresses a recently reported phenomenon that a simultaneous application of energetic particle radiation, electric field, and elevated temperature for an extended period of time has a permanent adverse effect on insulating ceramics, including electrical breakdown. This behavior poses a serious challenge for fusion devices, which require electrical insulators in several key component...

Fluoride varnishes in caries prevention.

The first fluoride varnishes were developed during the 1960s (Duraphat) sodium fluoride varnish) and 1970s (Fluor Protector) silane fluoride varnish) to prolong the contact time between fluoride and enamel. Fluoride varnishes adhere to enamel, and calcium fluoride formed after application acts as a long-term reservoir of fluoride. Currently Duraphat varnish is the most widely used topical fluor...
