Journal ArticleDOI
Preparation of porous biodegradable microspheres with direct melting dispersion method
TL;DR: In this paper, polyhydroxybutyrate (PHB) was adopted as the biodegradable polymer and magnetite powder was pre-mixed into the melted polymer and removed by hydrochloric acid aqueous solution after preparation of the microspheres to make them porous.
Journal ArticleDOI
Optical multi-stability of bimesogenic cholesteric liquid crystal
TL;DR: In this paper, a bimesogenic cholesteric liquid crystal material with a proper chiral additive and check its potential as an energy saving transmissive type liquid crystal display (LCD) through its electro-optic characteristics.

TL;DR: Disclosed is a method for manufacturing a substrate which comprises a step wherein metal particles are deposited on a certain position of a substrate by a fine inkjet method and then sintered, thereby forming a metal column as discussed by the authors.
Proceedings ArticleDOI
Study on analysis of thick plate and multi-layer slab with various mixed boundary conditions
Patent
Maskless process for pre-tilting liquid crystal molecules
TL;DR: In this paper, a photo alignment layer is exposed to patterned light that is incident on the substrate at a substantially normal angle, which is polarized in a polarization direction that is non-parallel to an incident surface of the substrate.
