Permselectivity reveals a cool side of nanopores
Researchers from Osaka University investigated the thermal energy changes across nanopores that allow the selective flow of ions. Switching off the flow of ions in one direction led to a cooling effect. The findings have applications in nanofluidic d.....»»
Researchers transform captured greenhouse gases into cyclic carbonates with biomass derivatives
Carbon dioxide is the main contributor to greenhouse gas emissions, which are responsible for global warming and climate change. Direct capture of CO2 in the air is one of the solutions proposed to reduce its concentration in the atmosphere, but comb.....»»
Researchers serve up an improved model of indoor pollution produced by cooking
Stir-frying yields more than just tasty dishes like Kung Pao chicken and Hunan beef. It also emits an invisible mixture of gases and particles that pollute indoor air and can be detrimental to human health. Correctly estimating such cooking emissions.....»»
Recent advances in built-in electric-field-assisted photocatalytic dry reforming of methane
Methane (CH4) and carbon dioxide (CO2) are the two main greenhouse gases that cause global warming. Dry reforming of methane (DRM) technology can simultaneously utilize two greenhouse gases to produce hydrogen (H2) and carbon monoxide (CO), meaning D.....»»
Capital, canaries, or catalysts: Insurance industry"s role in tackling climate change risks
