Versatile controlled ion release for synthesis of recoverable hybrid hydrogels with high stretchability and notch-insensitivity
A versatile ion release mediated by GDL is demonstrated to achieve a controlled homogeneous crosslinking of alginate chains, which is critical for the synthesis of highly stretchable and notch-insensitive hybrid hydrogels with controlled properties.

Well-defined high refractive index poly(monothiocarbonate) with tunable Abbe''s numbers and glass-transition temperatures via terpolymerization
The synthesis of thermoplastics with high refractive index (n) and high Abbe’s number (Vd) is rarely reported. This work describes well-controlled synthesis of a soluble poly(monothiocarbonate) with high n and Vd values by using carbonyl sulfide (COS) as sulfur resource. The alternating COS/cyclohexene oxide (CHO)/propylene oxide (PO) terpolymerization was well performed by using...

Synthesis of High Molecular Weight Cyclic Poly(ε-caprolactone)s of Variable Ring Size Based on a Light-Induced Ring-Closure Approach
High molecular weight cyclic poly(ε-caprolactone)s (cPCLs) with variable ring size are synthesized via light-induced ring closure of α,ω-anthracene-terminated PCL (An-PCL-An). The ring size of cPCL is tunable simply by adjusting the polymer concentration from 10 to 100 mg mL?1 in THF. The cycloaddition via the bimolecular cyclization of An-PC-An is well characterized by a variety of ...

Driving of Droplet on Nano-Gradient Microhump Surface in Low-Temperature and High-Humidity Environment
Directional driving of a droplet can be achieved on a gradient-exhibiting,nanostructured microhump (GNMH) surface at low temperature and high humidity. The GNMH surface is fabricated using a commercial carbon fiber plate with an array of microscale hump structures; nanotechniques are used to form varying nanostructures on the microhump array, producing the micro- and nanostru...

[2015][Macromolecules, 2015, 48 (12), 3941–3948]Optimization of Broad-Response and High-Detectivity Polymer Photodetectors by Bandgap Engineering of Weak Donor–Strong Acceptor Polymers
A series of weak donor–strong acceptor polymers containing two different electron-deficient units (diketopyrrolopyrrole and thienoisoindigo) are synthesized and used in broad-response and high-detectivity polymer photodetectors. By adjusting the composition ratio of the two acceptors, the absorption spectra, energy levels, molecular stacking, and film morphology are affected, which in turn infl...

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...
