Engineering Spin State of Ni Single‐Atoms to Enhance Electrocatalytic Activity of Sulfur Conversion in Lithium–Sulfur Batteries

Carbon Energy, EarlyView.
Ni SACs with high‐spin state show strong catalytic activity toward lithium polysulfides (LPSs), whereas the Ni SACs with low‐spin state have strong adsorption capacity for LPSs. Therefore, the preparation of Ni SACs with an intermediate spin state by controlling pyridinic N and pyrrolic N enables an excellent balance between the adsorption and ...

Rethinking Climate Change on the Role of Human Power Generation, Alternative Perspectives, Potential Solutions, and a Plea for Action

Chemie Ingenieur Technik, EarlyView.
All energy matters Let us broaden the discussion on solutions to climate change. Greenhouse gases have upset the delicate equilibrium of the Earth's energy balance. Consequently, all sources of heat affect the temperature of the Earth. Although the amount of additional heat generated by humans is a fraction of that produced by the sun, it is generated ...
