Dynamic, temperature-driven transformation of the shape and morphology of polymer particles is demonstrated using polystyrene-b-poly(4-vinylpyridine) block copolymers (BCPs) and temperature-responsive poly(N-isopropylacrylamide) (PNIPAM) surfactants. The temperature-directed positioning of PNIPAM, depending on its solubility, determines both the shape and morphology of the BCP particles, suggesting great promise of these particles for use in sensing, smart coatings, and drug delivery applications.

Design and use of synthetic regulatory small RNAs to control gene expression in Escherichia coli Seung Min Yoo,1, 2 Dokyun Na1, 2, 3 & Sang Yup Lee1 Journal name:Nature Protocols Volume:8, Pages: 1694–1707 Year published:(2013)DOI: doi:10.1038/nprot.2013.105 Published online 08 August 2013 Abstract Gene knockout experiments are often essential in functional genomics and metabolic...
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...
