Nearly 60% of gasoline’s total energy is lost in the form of heat in the radiator and exhaust pipe, even in the most fuel-efficient cars. In order to overcome this, scientists have been creating innovative thermoelectric materials with the ability to transform heat into electricity.
In a progress that makes a more flexible, economical type of solar cell commercially feasible, researchers at the University of Michigan have showcased organic solar cells that can attain 15% efficiency.
During desert rainfall, cacti immediately start taking up & storing the precipitation. Researchers have now created a material inspired by this natural phenomenon. It imitates cactus roots’ ability to quickly absorb & retain huge quantities of water with least amount of evaporation.
Researchers have developed a technique to keep certain proteins active outside of the cell; making mats that can absorb & trap chemical pollution.
Javier Vela and the chemists in his Iowa State University research group faced an issue wherein a toxic material performed very well in solar cells.
An international research team led by the University of Cambridge discovered that the incorporation of potassium iodide ‘healed’ the defects and immobilized ion movement, which, thus far, have restricted the efficiency of economical perovskite solar cells.
Snowbanks, often formed by snow plows as they clear major roadways, can stay on sidewalks, in parking lots, and in driveways even when temperatures rise.
With technological progress in electric cars & mobile devices, the worldwide demand for lithium has outpaced the rate at which it can be recycled or mined.
Researchers are currently involved in designing new materials for the construction of wind turbines which are resistant to extreme climate.
Lina Hockaday, Senior Engineer in Pyrometallurgy at Mintek’s New Technology Group in South Africa, suggests that solar thermal reactors, able to attain temperatures up to 1200 °C, could almost eliminate emissions from processing manganese ore fines, by using solar sintering.
