228. Hierarchical ZnCo2O4@NiCo2O4 Core-Sheath Nanowires: Bifunctionality towards High-performance Supercapacitors and Oxygen Reduction Reaction
Increasing energy demands and worsening environmental issues have stimulated intense research on alternative energy storage and conversion systems including supercapacitors
and fuel cells. Here, a rationally designed hierarchical structure of ZnCo2O4@NiCo2O4 core–sheath nanowires synthesized through facile electrospinning combined with a simple co-precipitation method is proposed. The obtained co...

High-Performance Electrocatalysts for Oxygen Reduction Based on Nitrogen-Doped PorousCarbon from Hydrothermal Treatment of Glucose and Dicyandiamide
A synthetic method was developed for the preparation of Ndoped
porous carbon through hydrothermal treatment at controlled
temperatures by using glucose and dicyandiamide as
precursors and ZnCl2 as an activation reagent. Nitrogen doping
was quantitatively determined by using XPS measurements
and identified in the forms of pyridinic, pyrrolic, graphitic, and
pyridinic N+Onitrogen atoms. Further st...

High-efficiency grafting of halloysite nanotubes by using p-conjugated polyfluorenes via ‘‘click’’ chemistry
New hybrid halloysite nanotubes (HNTs) were
obtained by grafting conjugated polyfluorenes (PFs) onto
the surface via ‘‘click’’ chemistry. The hybrid material can
be dispersed in organic solvent such as dichloromethane,
and exhibits intense blue emission peaked at 448 nm. The
absorption and emission spectra of the HNTs show distinct
bathochromic shifts compared to PFs, which can be attributed
t...

Multiscale carbon nanosphere–carbon fiber reinforcement for cement-based composites with enhanced high-temperature resistance
A novel multiscale reinforcement was prepared
by the fast growth of carbon nanospheres (CNSs) onto the
surface of carbon ?ber (CF) under mildly hydrothermal
reaction. The uniform layer of CNS with an average
diameter of 85 nm produced on the ?ber surface. Further,
the structural analysis, surface morphology, and thermal
decomposition behavior of CNS–CF reinforcement were
studied by X-ray diffra...

[2014][J. Mater. Chem. C, 2014,2: 2431-2438]Panchromatic Small Molecules for UV-Vis-NIR Photodetectors with High Detectivity
Two donor–acceptor–donor (D–A–D) type low-bandgap small molecules, M1 and M2, with bis(2-thienyl)-N-alkylpyrrole (TPT) as the donor and thieno[3,4-b]thiadiazole (TT) as the acceptor were designed and synthesized. The absorption, transmission, electrochemical, thermal and film properties were studied. The compounds showed panchromatic absorption in the spectral range of 300–1000 nm. Moreover...

[ACS Appl. Mater. Interfaces] Soluble and Meltable Hyperbranched Polyborosilazanes toward High-temperature Stable SiBCN Ceramics
High-temperature stable siliconborocarbonitride (SiBCN) ceramics
produced from single-source preceramic polymers have
received increased attention in the last two decades. In this contribution, soluble and meltable polyborosilazanes
with hyperbranched topology (hb-PBSZ) were synthesized via a convenient solvent-free, catalyst-free and one-pot A2+B6 strategy—an
aminolysis reaction of the A2...

[Macromolecules] Synthesis and Characterization of Comb and Centipede Multigraft Copolymers P n BA-g-PS with High Molecular Weight Using Miniemulsion Polymerization
ABSTRACT: Comb and centipede multigraft copolymers, poly( n-butyl acrylate)- g-polystyrene (PnBA-g-PS) with PnBA backbones and PS side chains, were synthesized via highvacuum anionic polymerization and miniemulsion polymerization. Single-tailed and double-tailed PS macromonomers were synthesized by anionic polymerization and Steglich esterification. Subsequently, the copolymerization of each macro...

Insights into the surface property and blood compatibility of polyethersulfone/polyvinylpyrrolidone composite membranes: toward high-performance hemodialyzer
Applications of blood purificationmembranes are fuelled by diverse clinical needs, such as hemodialysis, hemodiafiltration, hemofiltration, plasmapheresis, and plasma collection. For clinical usage, the adding of polyvinylpyrrolidone (PVP) is the general protocol for the design of antifouling and antithrombotic properties integrated artificial membranes. In the present work, to insigh...

215. High-performance flexible supercapacitors based on mesoporous carbon nanofibers/Co3O4/MnO2 hybrid electrodes.
In this work, self-standing Co3O4 doped CNF (CNFs/Co3O4) membranes were prepared through a facile sol–gel electrospinning and high-temperature carbonization process, followed by a subsequent in situ redox reaction in KMnO4 solution to obtain mesoporous MnO2 sheets coated CNFs/Co3O4/MnO2 composite membranes. The as-fabricated flexible CNFs/Co3O4/MnO2 membrane electrodes exhibit superior capacitive...
