Cage Effect of Nitrogen Oxide Radicals Enables Li‐NOx Cell with a 3.8 V Cell Voltage
Advanced Materials, EarlyView.A novel Li‐NOx battery chemistry achieves reversible 3.8 V operation by harnessing the cage effect of nitrogen oxide (NO) radicals. This strategy establishes a viable NOx redox mechanism for high‐voltage energy storage and presents a sustainable route for NOx valorization.

Combustion Characteristics of Combustion Chamber Using Compost as a Fuel
Energy Procedia, 2014 AbstractThe aim of the present study is to develop the biomass furnace combustor which can effectively use the compost as a fuel. Here, the compost which is made from pig's waste and has the calorific value of 2000kcal/kg, is employed here. Emphasis is placed on the optimum conditions of fuel and air flow rates, moisture content of the compost and the ...
