a) Schematic: Metal foil inserted for internal heating and fast heat transfer to electrodes and electrolyte. Self-heating activated by switching off the connection between activation terminal and negative terminal. b) Evolution of cell voltage and temperature during activation at Vact = 0.4 V (inset) and subsequent 1C discharge at −20 °C. Battery temperature increases from −20 °C to 0 °C...
A microbial fuel cell buried in soil and generating powerBill Yen/Northwestern UniversityA groundbreaking innovation from Northwestern University showcases a compact device capable of producing electricity by harnessing the power generated as microbes decompose soil, as long as there is carbon present.This device, about the size of a paperback book, operates on microbial fuel...
UCSB's adaptive roof tiles are actuated by the phase changes of wax, and can passively stabilize room temperature to radically reduce the energy cost of heating and coolingUC Santa BarbaraBy employing a temperature-sensitive "wax motor," scientists have developed a dynamic roofing tile system that maintains a comfortable room temperature of 18 °C (65 °F)....

A study (An international stock), revealed that CO2 escapes from oil refineries were as high as, 1.3 Gt in 2018 and could reach 16.5 Gt from 2020 to 2030. From the results, the investigators suggest unique mitigation techniques for such refineries in various regions and ages. The results appear today (20 August 2021) in...
