Abstract:
... Carbon-fiber-reinforced plastic (CFRP) can be difficult to recycle owing to the presence of thermosetting plastics such as epoxy resin. Therefore, it is important to develop more efficient methods for recycling CFRP. Herein, we investigated the chemical recycling of CFRP containing an epoxy matrix resin via a process involving superheated and supercritical acetone. The decomposition efficiency of ...

Abstract:
... Coil–coil block copolymers rarely self-assemble into flat low-curvature micelles due to the lack of proper interchain association. Here, we report a facile route to prepare disk-like micelles through the self-assembly of amphiphilic polystyrene-b-polybutadiene-b-poly(2-vinylpyridine) triblock copolymers in a mixture of acetone and cyclohexane, which shows distinct selectivity towards the PS, PB an ...

Despite their bioactivity, the molecular composition of native and oxidized procyanidins is little understood. In this paper, polyphenols from litchi pericarp were extracted using two solvents (methanol and acetone). The mean degree of polymerization (mDP) of native and identification of oxidized PCs were car ...

Abstract:
... Transfer of chemical-vapor-deposition (CVD) grown monolayer graphene from one substrate to another requires a transfer agent. The transfer agent usually needs to be removed by washing with organic solvent such as acetone or high temperature annealing, which is harmful to the structure integrity and intrinsic property of a graphene film. Here, we propose the use of camphor as a transfer agent to tr ...
