Precise synthesis of sulfur-containing polymers via cooperative dual organocatalysts with high activity
关键字：Metal-free，carbonyl sulfide，100% alternating degree
Metal-free and controlled synthesis of sulfur-containing polymer is still a big challenge in
polymer chemistry. Here, we report a metal-free, living copolymerization of carbonyl sulfide
(COS) with epoxides via the cooperative catalysis of organic Lewis pairs including bases (e.g.:
phosphazene, amidine, and guanidine) and thioureas as hydrogen-bond donors, afford welldefined poly(monothi...

Readily recyclable, high-performance thermosetting materials based on a lignin-derived spiro diacetal trigger
关键字：/
Conventional thermosets, widely used in composites, coatings, electronic packing materials, etc., are typically made of non-sustainable fossil resources and cannot be recycled under mild conditions. Degradable thermosets are promising alternatives, while combining ready degradability and high performance is a challenge. In this paper, for the first time, a spiro diacetal structure was utilized t...

Catechol-functionalized microporous organic polymer as supported media for Pd nanoparticles and its high catalytic activity
关键字：microporous organic polymer
We report a new hydroxyl functionalized microporous organic polymer (MOPOH) based on the polymerization of catechol with terephthalaldehyde using phenolic resin-inspired chemistry. This catechol-decorated material, with surface area of 874 m2 g?1 and micro, mesopores, facilitates the immobilization and dispersion of Pd nanoparticles (NPs) on the polymer matrix. The surface area of t...

Assembly of an unbalanced charged polyampholyte onto Nafion to produce high-performance composite membranes
关键字：polyampholyte, Nafion, membrane
A novel SPES-NH2–GA-Nafions composite membrane with higher proton conductivity and lower methanol permeability was fabricated by covalent crosslinking layer-by-layer self-assembly of an unbalanced charged polyampholyte (SPES-NH2) and glutaraldehyde (GA) with controllable free sulfonic acid content.

Driving of Droplet on Nano-Gradient Microhump Surface in Low-Temperature and High-Humidity Environment
关键字：Gradient
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 fi ber
plate with an array of microscale hump structures; nanotechniques are used
to form varying nanostructures on the microhump array, producing the
micro- and nanostructured surface. The ...

A Core-shell Nanostructure Ensures High Gene Transfection Efficacy and IVIinimal Cytotoxicity
关键字：core-shellnanostructure dendrimer polyethyleneimine gene delivery
Cationic dendrimers and polyethyleneimine (PEI) have been widely investigated both in vitro and in vivo. Generally, high generation dendrimer and high molecular weight PEI possess relatively high transfection efficacy, but they are associated with serious cytotoxicity during gene transfection. In comparison, low generation dendrimer and low molecular weight PEI has good
biocompatibility but poo...

A Visualization Method to Investigate the Mechanism of Cell Nucleation and Growth in High-Pressure Foam Injection Molding
Introduction
Foam injection molding (FIM) is one of the most promising technologies owing to its ability to
produce low-density parts with high geometrical accuracy and stiffness-to-weight ratio at fast
production cycles [i]. In this technology, a gas-charged melt is being injected into a confined cavity.In low-pressure FIM, i.e. short shot injection, foaming occurs due to the pressure drop ov...
