Cultiva-tion in internal-loop airlift photobioreactors under optimal light setting based on two-staged study and optimal aeration rate at 0.8 vvm produced higher biomass (855 ± 26 mg L-1) and carotenoid (8.11 ± 0.20 mg L-1 or 9.23 ± 0.23 mg g-1) than the cultivation in stirred-tank systems with the same volume and operating condition. HPLC analysis of biomass from airlift photobioreactors revealed that lutein, violaxanthin and neoxanthin were major carotenoids.The pore structure of nickel oxide-yttria stabilized zirconia (NiO-YSZ) anode-supported solid oxide fuel cell (SOFC) were investigated using two types of pore formers. They are organic materials of rice starch and corn starches. The Influence of pore formers on the porosity and microstructure of the supported-anodes were stud-ies. The results revealed that the pore structure of the anodes was related to the shape of the pore formers. The corn starch pore former exhibited highest porosity before and after reduction. From this study, it is suggested that corn starch is the most promising pore formers for the supporting anodes for SOFC application which could be related to the pore structure of the anode.Despite numerous studies have shown that solitary native bee communities can increase crop yield when used synergistically with honey bees, few rearing systems for solitary bees were established that can be used for pollination. Here, potential crop pollinators from genus Megachile (Callomegachile; aka resin bees) in Thai-land are reviewed. Artificial trap nests for Callomegachile were designed to lure bees to nest. Trap nests were monitored periodically, whereas resident bees were captured for identification. In addition, specimens depos-ited in major natural history museums were examined to complement the data obtained from trap nests. Fifteen Callomegachile species are recognized from this study with two new records for Thailand. Three putative new species are described: M. calvathorax n. sp., M. chiangmaiensis n. sp. and M. fuscohirsuta n. sp. This research is the first to identify megachilid bees have the potential to be housed in trap nests, which can be conveniently transport among orchards for crop pollination.Supercapacitors have received recent attention as a type of energy storage device due to their prominent advan-tages such as fast charging and discharging high power density, stability, and cost competitiveness compared to conventional battery devices. The goal of this work is to improve the energy density of supercapacitor by introducing a new composite material made of reduced graphene oxide (rGO) and NiCoAl layered double hydroxide (NiCoAl-LDH). In this design, rGO and NiCoAl-LDH nanosheets were combined into one hierar-
