Recent Advances in Ionizing Radiation as a Nonequilibrium Chemical Field for Catalysis
Carbon and Hydrogen, EarlyView.Ionizing radiation acts as a nonequilibrium chemical field that generates reactive species and structural perturbations. These radiation‐induced effects bridge catalytic material construction, including metal loading, framework evolution, defect engineering, and carbon‐network reorganization, with selective transformations such as oxidation, reduction,

Coupling Pumped Hydro Energy Storage With Unit Commitment [PDF]
IEEE Transactions on Sustainable Energy, 2016 Renewable electricity generation not only provides affordable and emission-free electricity but also introduces additional complexity in the day-ahead planning procedure. To address the stochastic nature of renewable generation, system operators must schedule enough controllable generation to have the flexibility required to compensate unavoidable real-

Hydrogen donor‐assisted visbreaking of Canadian oil sands bitumen
The Canadian Journal of Chemical Engineering, EarlyView.Abstract High‐viscosity Canadian oil sands bitumen requires processing for efficient transportation and refining. Partial upgrading technologies, primarily based on thermal processing, can effectively reduce, or even eliminate, the use of costly diluent, increase bitumen quality and market value, potentially decrease greenhouse gas (GHG) emissions, and
