Advances in Triboelectric Nanogenerators With Rotating Structure

open access: yesCarbon Energy, EarlyView.
The rotating TENG has been widely studied for its superiorities of simple structure, high efficiency, and stable output. This review introduced the four different principles of rotating TENG and offered a thorough summary for performance and application research through three‐level classification. Importantly, the current existing problems, challenges,

Incident shock-wave characteristics in air, argon, carbon dioxide, and helium in a shock tube with unheated helium driver [PDF]

open access: yes
Incident shock-wave velocities were measured in the Langley 6-inch expansion tube, operated as a shock tube, with air, argon, carbon dioxide, and helium as test gases. Unheated helium was used as the driver gas and most data were obtained at pressures of

Modulating Metal–Oxygen Bond Energy by Valence State Engineering in 2D High Entropy Oxides for Enhanced Water Electrolysis

open access: yesCarbon Energy, EarlyView.
The competitive redox equilibrium among different elements in 2D HEO is regulated through temperature‐controlled pyrolysis of 2D HEHO, obtaining 2D HEO with a continuously adjustable valence state of Fe, Ni, Mo, Ru, and V elements, which modulate the strength of the metal–O bond and activate the LOM‐OVSM for OER.
