[ACS Sensor] Ultrafast and Efficient Detection of Formaldehyde in Aqueous Solutions Using Chitosan-based Fluorescent Polymers
Detection of a toxic formaldehyde (HCHO) pollutant in aqueous solutions is of significant importance, because HCHO is widely found in aquatic food because of illicit addition or improper storage. Many small-molecule-based fluorescent probes, which rely on HCHO-specific formaldehyde-amine condensation or the aza-Cope rearrangement reaction, have been developed in terms of facile operation and high ...

111. Single crystals of crystalline block copolymers formed in n-hexanol and methanol/DMF solutions: A comparative study
Lamellar single crystals of poly(?-caprolactone) (PCL)-based crystalline/liquid-crystalline block copolymer (BCP) were prepared from two methods: solution crystallization in n-hexanol, as well as addition of methanol dropwise to BCP/DMF solution. The crystalline morphologies of PCL single crystals prepared at different temperatures were investigated. It was observed that well-developed single crys...

[Reactive and Functional Polymers]RAFT polymerization and dually responsive behaviors of terpyridine-containing PNIPAAm copolymers in dilute solutions
Introduction of new components is an effectiveway to gain new functionalities and to regulate the
properties of responsive polymers. In the presentwork, a RAFT polymerization approach to terpyridine-containing poly(N-isopropyl acrylamide) (PNIPAAm) copolymers was developed and the dually responsive behavior of the obtained polymer to temperature variation and metal ions in dilute solutions were ...

Functional short-chain zwitterion coated silica nanoparticles with antifouling property in protein solutions
A new functional nanoparticle, consisting of a silica core onto which short-chain zwitterions are chemically connected, was successfully prepared and showed excellent antifouling performance to protein solutions. These nanoparticles (NPs) own excellent stability even in 1 M NaCl solutions for at least 48 h. The interaction between these “zwitterated” NPs and proteins were investigated by dynamic...

Liquid Crystalline Transition and Gel-Sol Transitions for concentrated Microcrystalline Cellulose (MCC)/1-Ethyl-3-Methylimidazolium Acetate (EMIMAc) Solutions
Liquid crystalline (LC) phase transition and gel?sol transition in the solutions of microcrystalline cellulose (MCC) and ionic liquid (1-ethyl-3-methylimidazolium acetate, EMIMAc) have been investigated through a combination of polarized optical microscope (POM) observation and rheological measurements. Molecular LC phase forms at the 10 wt % cellulose concentration, as observed by POM, whereas th...

Kinetically Driven Intra- and Interchain Association of Hydrophobically and Hydrophilically Modified Poly(acrylic acid) in Dilute Aqueous Solutions
Effects of pH, dodecyl, and PEO contents as well as the method of preparing the solution on the formation of the unimolecular micelles (unimer micelle) or aggregates made of poly(acrylic acid)-graftpoly( ethylene oxide)-graft-dodecyl (PAA-g-PEO-g-dodecyl) and PAA-g-dodecyl have been studied by a combination of static and dynamic laser light scattering (SLS and DLS). It revealed th...
