Photonicmicrocapsules with onion-like topology are microuidically designed to have cholesteric liquid crystals with oppositehandedness in their core and shell. The microcapsules exhibit structural colorscaused by dual photonic bandgaps, resulting in a rich variety of color on theoptical palette. Moreover, the microcapsules can switch the colors from eithercore or shell depending on the selection of light-handedness.

Abstract: Pristine graphene quantum dots and graphene oxide quantum dots are synthesized by chemical exfoliation from graphite nanoparticles with high uniformity in terms of shape (circle), size (less than 4 nm), and thickness (monolayer). The origin of the blue and green photoluminescence of GQDs and GOQDs is attributed to intrinsic and extrinsic energy states, respectively. Further d...
ABSTRACT: Fumaric acid is a naturally occurring organic acid that is an intermediate of the tricarboxylic acid cycle. Fungal species belonging to Rhizopus have traditionally been employed for the production of fumaric acid. In this study, Escherichia coli was metabolically engineered for the production of fumaric acid under aerobic condition. For the aerobic production of fumaric acid, t...
