The emergence of heterogeneous photocatalysis has facilitated redox reactions with high efficiency, without compromising the recyclability photocatalyst. Recently, stimuli-responsive photocatalytic materials have emerged as a powerful synthetic tool, simple and rapid recovery, well an enhanced dynamic control over reactions. Stimuli-responsive polymers are often inexpensive easy to produce. The...

triphenyl phosphine(pph3), an efficient and reusable catalyst, catalysed the synthesis of 2-amino-3-cyano-6-methyl-4-aryl-4h-pyran-5-ethylcarboxylate derivatives by one-pot condensation of aromatic aldehydes, malononitrile and ethyl acetoacetate in etoh-h2o (1:1) at reflux conditions. the results show that aromatic aldehydes containing electron-donating groups or electron-withdrawing groups cou...

The research and development of bio-based electronegative tribolayers will accelerate the further application green triboelectric nanogenerators (G-TENGs), which is beneficial to alleviate environmental pollution caused by non-recyclability...

Novel hybrid material poly(imide-imine) has been prepared, which exhibits self-healing behavior and recyclability enabled by the dynamic imine bonds while retaining tunable excellent mechanical thermal properties of polyimide.

Poly(ethylene furanoate) (PEF) films were first produced using thermo-compression. Thereafter, the chemical recyclability was demonstrated in presence of a thermally stable organocatalyst followed by its repolymerization.

The world is facing a growing neodymium demand, creating the need for developing recycling system to handle future waste flows. Recycling technologies are emerging, but around them can only be established with knowledge about available end-of-life (EoL) products. Therefore, this study quantified in European countries using material flow analysis, and assessed recyclability of major EoL For 2019...

Waste plastics may be an environmentally friendly alternative to natural aggregates for concrete manufacture. However, the inferior bond strength between waste plastic and cement matrix greatly limits uses of engineering designs applications. Herein, ethylene–vinyl acetate (EVA) nanosilica (nS) were jointly employed enhance matrix-aggregate interactions in cementitious composites with recycled ...

Current search for more sustainable plastics seeks to redesign polymers possessing both chemical recyclability monomer a circular economy and desirable performance that can rival or even exceed today's non-recyclable hard-to-recycle petroleum-based incumbents. However, within traditional framework it is challenging optimize, concurrently, contrasting polymerizability/depolymerizability recyclab...
