High‐Performance Zero‐Gap Glycerol‐Fed Electrolyzer for C3 Chemicals and Hydrogen Production

Advanced Materials, EarlyView.
This work presents a dynamic, self‐regulating operation strategy that enables selective glycerol electrooxidation in the OER‐free regime, co‐producing C3 chemicals and hydrogen at cell voltages below 1.25 V. Voltage‐ and temperature‐resolved analyses define optimal operating conditions, achieving a sustained current density of 500 mA cm−2 at ∼1.21 V ...

Synergism between lignite and high-sulfur petroleum coke in CO2 gasification

Green Processing and Synthesis, 2023
High-sulfur petroleum coke (PC) as solid waste has high treatment cost. Gasification technology can utilize PC and lignite for co-gasification. Organically combining the two is the key to expanding the adaptability of gasification raw materials.

The Viability of Interstate Collaboration in the Absence of Federal Climate Change Legislation [PDF]

, 2011
Torrefaction of biomass together with gasification in entrained-flow reactors is a new possible way of producing synthesis gas. The synthesis gas can later be used for the production of renewable liquid fuels. This is highly desirable since the transport

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

Advanced 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.

Sharp Diamond Needles for Single‐Photon Emission

Advanced Photonics Research, EarlyView.
We study the morphological evolution of single‐crystal diamond needles oxidized at 650–700 °C. Electron microscopy and photoluminescence reveal temperature‐ and time‐dependent sharpening, length reduction, and surface modifications affecting tip properties.
