Three‐Dimensional Highly Thermally Conductive Graphene Blocks by Multiscale Blending and Multistage Pressure Induction

Carbon Energy, EarlyView.
An expandable‐thickness graphene block (GPB) with high thermal conductivity synthesized through multiscale blending and multistage pressure induction (MBP) achieves a record thickness of 12.1 mm, which is more than 10 times that of existing graphene materials. The maximum thermal diffusion ability of GPB‐MBP reaches 6.3 W/K, which offers a new approach

Plasmakristall‐4 Experiment: 10 Years of Operation in Orbit

Contributions to Plasma Physics, EarlyView.
ABSTRACT Plasmakristall‐4 (PK‐4) is a microgravity complex plasma laboratory operated for 10 years on board the International Space Station. Its main purpose is the particle‐resolved investigation of generic condensed matter phenomena using strongly coupled suspensions of microparticles immersed in low‐pressure gas‐discharge plasmas.

Effects of radiation, curvature, and preferential diffusion on the extinction of laminar non-premixed flames

AIP Advances, 2022
The combined effects of radiative heat loss, curvature, and preferential diffusion on laminar non-premixed flames (or flamelets) are investigated in this work by using asymptotic analysis.
