2017-JMCB: High Strength and Self-Healable Gelatin/Polyacrylamide Double Network Hydrogels
Double network (DN) hydrogels composed of two different polymer networks with strong asymmetry are excellent structural platforms to integrate different mechanical properties into a single material. However, simultaneously achieving high strength and self-healing property in DN hydrogels still remain a challenge. In this work, we design and synthesize Gelatin/Polyacrylamide (Gelatin/PAAm) DN gels ...

A General Direct C-H Coupling Method for Preparing Conducting Polymers with High Regioregularity
The Pd-catalysed oxidative C–H/C–H coupling reaction of 3-octylesterthiophene has been used for the first time to synthesize regioregular, head-to-tail coupled poly(3-esterthiophene).

Nanomolar colorimetric quantitative detection of Fe3+ and PPi with high selectivity
A novel rhodamine and 8-hydroxyquinoline-based derivative was synthesized, which is shown to act as a calorimetric chemosensor for Fe3+ in aqueous solution with high selectivity over various environmentally and biologically relevant metal ions and anions with a distinct color change from colorless to pink in very fast response time (<1 min). Fe3+ can be detected quantitatively in the concentrat...

Novel approach to extract thermally stable cellulose nanospheres with high yield
A facile approach for extracting cellulose nanospheres (SCNCs) was presented through hydrochloric acid hydrolysis of lyocell fibers under hydrothermal condition. The SCNCs showed spherical nanoparticles with an average diameter of 25 nm. Compared to the lyocell fibers, high yield of up to 85.3%, crystallinity of 85.2% and the maximum degradation temperature (Tmax) of 347.2 1C for ...

30. Synthesis and Properties of Cross-Linkable High Molecular Weight Fluorinated Copolyimides
A series of novel high molecular weight fluorinated co-polyimides (Co-PIs) containing styryl side chain based on 1,3-bis(2-trifluoromethyl-4-aminophenoxy)-5-(2,3,4,5-tetrafluorophenoxy)benzene (6FTFPB) were successfully synthesized. The weight-average molecular weights (M(w)s) and polydispersities of the co-polyimides were in the range 8.93-10.81 x 10(4) and 1.33-1.82, respectively. The co-polyimi...

21. Preparation and properties of high-performance polyethersulfone composites reinforced by modified silicon nitride
Si3N4 fillers were added to polyethersulfone (PES) using the solution mixing and ball-mill mixing methods to increase the thermal conductivity. 3-Aminpropyltriethoxysilane was used as a coupling agent for the surface modification of the Si3N4 particles. The morphology, thermal stability, mechanical properties, and thermal conductivity of the Si3N4/PES composites were then studied in detail. The di...

Controlled droplet transport to target on a high adhesion surface with multi-gradients
We introduce multi-gradients including Laplace pressure gradient, wettable gradient and wettable different gradient on a high adhesion surface via special wedge-pattern and improved anodic oxidation method. As a result of the cooperative effect mentioned above, controlled directional motion of a droplet on a high adhesion surface is realized, even when the surface is turned upside down. The drop...

Improving the flame-retardant efficiency of aluminum hydroxide with fullerene for high-density polyethylene
The influence of fullerene (C-60) on the flame retardancy and thermal
stability of high-density polyethylene (HDPE)/aluminum hydroxide (ATH)
composites was studied. After the addition of three portions of C-60 to
an HDPE-ATH (mass ratio=100:120) composite, a V-0 rating in the UL-94
vertical combustion test was achieved, and the limiting oxygen index
increased by about 2%. The resu...

High Capacity Hydrogen and Nitric Oxide Adsorption and Storage in a Metal-Organic Framework
Gas adsorption experiments have been carried out on a copper benzene tricarboxylate metal?organic framework material, HKUST-1. Hydrogen adsorption at 1 and 10 bar (both 77 K) gives an adsorption capacity of 11.16 mmol H2 per g of HKUST-1 (22.7 mg g-1, 2.27 wt %) at 1 bar and 18 mmol per g (36.28 mg g-1, 3.6 wt %) at 10 bar. Adsorption of D2 at 1 bar (77 K) is between 1.09 (at 1 bar) and 1.20(at &l...
