A versatile surface modification technique was developed to yield poly(N-isopropylacrylamide) (pNIPAm) microgel-based thin films on a variety of substrates, e.g., metals, nonmetals, and polymers. Because the chemistry, and hence functionality and responsivity, of the pNIPAm-based microgels is...

The lithium–sulfur (Li–S) battery is regarded as a promising secondary battery. However, constant parasitic reactions between the Li anode and soluble polysulfide (PS) intermediates significantly deteriorate the working Li anode. The rational design to inhibit the parasitic reactions is plagued...

Nanogels with a biomolecular coating (biocoating) were shown to be capable of triggered delivery of anticancer drug Doxorubicin. The biocoating was formed utilizing binding between glycogen and the tetra-functional lectin Concanavalin A, which can be triggered to disassemble (and release) upon...

Ferrocene-modified poly(N-isopropylacrylamide)-based microgels were synthesized, characterized, and used to construct optical devices (etalons). The response of the microgels and etalons to H2O2 was investigated, and we show that both the microgel diameter and the optical properties of the...

A novel diblock copolymer composed of bisphosphonate and pyridine oligomers has been prepared by reversible addition–fragmentation transfer (RAFT) polymerization. Ag ion was introduced into the polymer via its coordination with the pyridine groups, followed by a reduction process to obtain Ag...

Lithium (Li) metal is strongly regarded as a promising anode for next-generation secondary batteries. However, the nonuniform plating/stripping and volume fluctuation of the Li metal anode give rise to low Coulombic efficiency and short lifespan of Li metal batteries, which hinder practical...
