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.
Researchers have developed a catalytic process for converting sugarcane biomass into a new class of aviation fuel and lubricant base oils that could help biorefineries achieve net life-cycle greenhouse gas savings of up to 80 percent.
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.
A new study has found for the first time that efforts to keep global temperatures in check will likely lead to more people going hungry. That risk, they say, doesn't negate the need for mitigation but highlights the importance of comprehensive policies.
In recent years lithium-ion batteries have gathered bad press. They offer disappointing battery life for modern portable devices and limited driving range of electric cars, compared to gasoline-powered vehicles. Lithium-ion batteries also have safety concerns, notably the danger of fire. This situation raises legitimate questions: What is coming next?
The 50 individual state plans call for aggressive changes to both infrastructure and the ways we currently consume energy, but indicate that the conversion is technically and economically possible through the wide-scale implementation of existing technologies.
Coating engine components with hard carbon reduces friction to almost zero - a development that could save billions of liters of fuel worldwide every year. Now researchers have developed a new laser method to apply the coating on the production line.
Researchers have found a more eco-friendly way to derive lignin - a paper industry waste product - from wood and convert it into chemical building blocks. The resulting chemicals can be used in paint, insulation foam, and several other products.
