Advanced Engineering Materials, EarlyView.The authors explore thermally initiated diazonium chemical surface modification as a means of improving the mechanical performance of milled carbon fibers in epoxy matrix systems at varying loadings by weight. They report significant improvements at <1% w/w loading through examination of flexural and tensile strength and modulus.

2D Covalent Moiré Superlattice from Fluorinating Twisted Bilayer Graphene
Advanced Functional Materials, EarlyView.A novel class of moiré materials, termed covalent moiré superlattice is proposed, which can be synthesized by functionalizing moiré van der Waals materials. By fluorinating twisted bilayer graphene, the weak van der Waals interactions between twisted graphene layers are transformed into strong covalent bonds, making the moiré superlattice effects ...

Electron properties of fluorinated single-layer graphene transistors [PDF]
Phys. Rev. B 82, 073403 (2010), 2010 We have fabricated transistor structures using fluorinated single-layer graphene flakes and studied their electronic properties at different temperatures. Compared with pristine graphene, fluorinated graphene has very large and strongly temperature dependent resistance in the electro-neutrality region.

Advanced Functional Materials, EarlyView.The developed all‐organic solar cells achieve a power conversion efficiency of 8.7%, more than double the previous record. In addition, bioplastic substrates are used to produce environmentally friendly solar cells with an efficiency of 8.6%. These results are achieved by developing high‐performance organic electrodes without acid doping or high ...
