Multi-vinyl linked benzothiadiazole conjugated polymers: high performance, low crystalline material for transistors.

In this work, we proposed a multi-vinyl linker fusing strategy for designing low crystallinity, high performance materials for organic field effect transistors. A corresponding conjugated polymer, PTBTV, base was synthesized, exhibiting an impressive hole mobility of up to 3.2 cm V s, yet grazing incidence X-ray diffraction revealed a relatively weak crystallinity in the thin film.

Polyhydroxybutyrate production from oil palm empty fruit bunch using Bacillus megaterium R11.

Oil palm empty fruit bunch (OPEFB), contains abundant cellulose and hemicelluloses and can be used as a renewable resource for fuel and chemical production. This study, as the first attempt, aims to convert OPEFB derived sugars to polyhydroxybutyrate (PHB). OPEFB collected from a Malaysia palm oil refinery plant was chemically pretreated and enzymatically hydrolyzed by an in-house prepared cellulase cocktail.
