We proposed a novel UV curable reactive mesogen monomer for VA-LCD with Polymer-Sustained (Stabilized) Vertical Alignment (PSVA) which shows a high display performance. The experimental results reveal that the PSVA by the novel-monomer realizes less image sticking and better response time. key words: polymer-sustained (polymer-stabilized), phase separation, reactive mesogen, VA-LCD, PSVA

A dual function UV curable resin, which contains both initiation and polymerization functional groups, was developed for applications where low migration is required. This low extractable resin was specifically designed for: 1) ease of use, 2) high compatibility, 3) photo activation under UVA excitation, and most importantly 4) negligible migration.

-Curing of paints by exposure to UV radiations is emerging as one of the best film forming technique as an alternative to traditional solvent borne oxidative and thermal curing coatings. The composition and chemistry of UV curable coatings and role of multifunctional and monofunctional monomers, oligomers, and photoinitiators have been discussed. The limitations imposed by thermodynamic equilib...

This paper presents UV imprinting methods for fabricating a high-aspect-ratio pillar array. A polydimethylsiloxane (PDMS) mold was selected as the UV imprinting mold. The pillar pattern was formed on a 50 × 50 mm area on a polyethylene terephthalate (PET) film without remarkable deformation. The aspect ratios of the pillar and space were about four and ten, respectively. The mold was placed int...

The formulations contained different acrylate monomer with different structure and functionalities and TiO2, were applied to obtain pigmented acrylic films by UV exposure. The conversion and mechanical characteristic were correlated. The results showed that there is a significant interaction between pigment, reactive diluents’ type and mechanical properties of coatings. It seems that cured film...

Inorganic UV filters have become attractive because of their role in protecting the skin from the damage caused by continuous exposure to the sun. However, their large refractive index and high photocatalytic activity have led to the development of alternative inorganic materials such as CePO4 for application as UV filters. This compound leaves a low amount of white residue on the skin and is h...

Famotidine belongs to H2-receptor antagonist. It is used widely for the treatment of treatment of (GERD) gastro-esophageal reflux disease and gastric ulceration duodenal ulcer, stress ulcer. A simple, efficient spectrophotometric method for the assay of famotidine has been developed for estimation of famotidine formulations. Comparision of three different brands of famotidine (nocid, famulcer a...
