Achievement of Transition Metal Chalcogenides/Oxides in Hydrogen Production by Seawater Electrolysis
EcoEnergy, EarlyView.Transition metal chalcogenides (TMCs)/oxides have shown great application potential in seawater splitting for hydrogen generation due to their adjustable electronic properties, abundant active sites, and excellent catalytic performance. ABSTRACT Under the impetus of global “dual carbon” goals, green hydrogen has become a key component of the future ...

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.This work employs a dual‐effect function strategy of Se to make an original composite material of selenium (Se) and activated carbon (AC) (designated as Se–AC), as a functional iodine‐adsorbed cathode host. Not only Se catalyzes the I0/I− conversion reaction, but also Se nanoparticles can adjust the charge distribution of AC to adsorb more I3−. Aqueous‐

Dynamic Gains from Trade: Evidence from South Africa [PDF]
This paper examines the empirical relationship between trade and total factor productivity (TFP) in South Africa. Using data on actual trade protection across different manufacturing sectors, it is shown that trade liberalization had a positive impact on

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.This study exploited the substitution doping of Mn and F in NiCo2O4 to activate and stabilize lattice oxygen, achieving a stable synergistic effect between AEM and LOM to enhance the intrinsic activity of the catalyst. The outstanding bifunctional properties enable its application as an anode catalyst in zinc–air batteries.

The Impact on U.S. Industries of Carbon Prices with Output-Based Rebates over Multiple Time Frames [PDF]
The effects of a carbon price on U.S. industries are likely to change over time as firms and customers gradually adjust to new prices. The effects will also depend on the number of countries implementing the policy as well as offsetting policies to ...

The Dimensional Revolution of Phosphorus: From Allotropicity to Battery System Applications
ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.Phosphorus‐based materials are promising high‐capacity anodes classified by dimension (0D–3D) to systematically explore their properties and composite strategies. When combined with materials such as carbon to form heterostructures, the electrical conductivity and stability are effectively enhanced.
