Fast and fully-scalable synthesis of reduced graphene oxide
TL;DR: The synthesis of RGO is reported by sonication-assisted oxidation of graphite in a solution of potassium permanganate and concentrated sulfuric acid followed by reduction with ascorbic acid prior to any washing processes to reduce graphene oxide to graphene oxide.

Plastic deformation behaviour of fine-grained materials
TL;DR: In this paper, a phase mixture model was proposed to describe the plastic deformation behavior of fine-grained materials, where a polycrystalline material was regarded as a mixture of a crystalline phase and a grain-boundary phase and the deformation mechanism was modelled as a diffusional flow of matter through the grain boundary.
Journal ArticleDOI
On the rule of mixtures for the hardness of particle reinforced composites
TL;DR: In this paper, the hardness variations with the volume fraction of the hard particle in the particle reinforced composite have been analyzed using several models for a rule of mixtures and finite element method.
Journal ArticleDOI
Cryogenic strength improvement by utilizing room-temperature deformation twinning in a partially recrystallized VCrMnFeCoNi high-entropy alloy

TL;DR: The results demonstrate that non-recrystallized grains, which are generally avoided in conventional alloys because of their deleterious effect on ductility, can be useful in achieving high-strength high-entropy alloys.
