Using solar energy to melt aluminium

Researchers and industry are cooperating within the SOLAM (solar melting of aluminium in a directly radiated rotary kiln) project to develop a method by which aluminium foundries could use solar energy to melt this metal. The method would allow the companies to reduce their electricity consumption to a great extent and substantially lower their carbon dioxide emissions.

Adding chemicals could make future battery technology safer

In a study that could improve the safety of next-generation batteries, researchers discovered that adding two chemicals to the electrolyte of a lithium metal battery prevents the formation of dendrites ?-'fingers' of lithium that pierce the barrier between the battery's halves, causing it to short out, overheat and sometimes burst into flame.

Key to quick battery charging time

Researchers have discovered the structure and transport properties of the 'intermediate state' in lithium-ion batteries - key to understanding the mechanisms of charge and discharge in rechargeable batteries. These findings may help accelerate battery reaction speed and significantly shorten battery charging time.

Hematite 're-growth' smoothes rough edges for clean energy harvest

Finding an efficient solar water splitting method to mine electron-rich hydrogen for clean power has been thwarted by the poor performance of hematite. But by 're-growing' the mineral's surface, a smoother version of hematite doubled electrical yield, opening a new door to energy-harvesting artificial photosynthesis, according to a new report.

New calculations to improve CO2 monitoring from space

How light of different colours is absorbed by carbon dioxide can now be accurately predicted using new calculations. This will help climate scientists studying Earth's greenhouse gas emissions to better interpret data collected from satellites and ground stations measuring CO2.
