Melt-quenching technique was used to prepare iron tellurite glasses in the system Fe2O3-Sb-TeO2. The findings indicate that the variation in conductivity on alternate switching of gas atmospheres between oxygen and argon is reproducible. Moreover, the results suggest the practicality of the 15Fe2O3-5Sb-80TeO2 glass as an O2 gas sensor as evidenced by its high oxygen gas sensitivity.

Nanoimprint lithography technology, which is able to easily create nanometer-resolution two-dimensional surface grooves on substrates over a large area by a step and stamp process, opens up an intriguing opportunity for functional liquid crystal (LC) alignment. We describe here a hybrid polymer consisting of two distinct moieties with largely different thermomechanical properties and surface activity. We present the results of nanoimprint lithography experiment using the hybrid polymer to demonstrate the practical applicability as an LC alignment layer. This material shows excellent capability both as a nanoimprinting material, requiring softness at moderate temperatures, and as a LC alignment layer, requiring sufficient rigidity. LC devices using the alignment layer show fairly stable electro-optic characteristics even after thermal aging, due to its high thermal stability. The soft component of the hybrid polymer helps it provide the multiple imprinting capabilities at higher temperatures virtually without any mold damages. [ABSTRACT FROM AUTHOR]

The concept of hybrid polymers is proposed for liquid crystal (LC) alignment by nanoimprint lithography (NIL) technology in order to optimize thermomechanical properties and surface activity that is important for the LC alignment. Results show that LC devices using the hybrid polymer layer have demonstrated stable electro-optic characteristics even after thermal aging.
