Tuning Pore Size in Porous Graphene Membrane for O2/N2 Separation

open access: yesAdvanced Materials, EarlyView.
Single‐layer graphene membranes featuring N‐functionalized, 0D pores offer a promising platform for O2/N2 separation. The heterogeneity of functional groups at the pore edge is dynamically tunable, enabling precise tuning of the pore limiting diameter and gas transport.

Synthesis and analysis of jet fuels from shale oil and coal syncrudes [PDF]

open access: yes
The technical problems involved in converting a significant portion of a barrel of either a shale oil or coal syncrude into a suitable aviation turbine fuel were studied. TOSCO shale oil, H-Coal and COED coal syncrudes were the starting materials.

EFFECTS OF FLOW ROUTING PLATE ON MIXED CONVECTION HEAT TRANSFER FROM PROTRUDED HEAT SOURCES

open access: yes, 2016
In this study, the effect of the flow routing plates on the laminar mixed convection heat transfer in a horizontal channel that has protruded heat sources at the bottom and top surfaces were investigated numerically and experimentally. The air was used as the cooling fluid, and protruded heat sources were equipped as 4x8 rows into the rectangle channel

Mechanically Tunable Mechanochromic Device with Covert‐Overt Structural Color and Modulation of its Transparency

open access: yesAdvanced Materials Interfaces, EarlyView.
This study presents a novel mechanically responsive optical device that modulates light transmission and generates iridescent structural colors under reflection. The optical transition arises from the exposure of nanoparticles upon stretching, which are initially embedded beneath the surface.
