Scientists working toward the elusive lithium-air battery discovered an unexpected approach to capturing and storing CO2 away from the atmosphere. Using a design intended for a lithium-CO2 battery, researchers in Japan and China have developed a way to isolate solid carbon dust from CO2, with the potential to also separate out oxygen gas through the same method. Converting carbon dioxide emissions into other carbon-containing compounds is desirable due to CO2’s contribution to the greenhouse effect and global warming...

Pilot plant produces first synthetic fuel from solar power and the air’s carbon dioxide/KIT spin-off ineratec supplied key component. Production of liquid fuels from regenerative electric power is a major component of the energy turnaround. The first 200 l of synthetic fuel have now been produced from solar energy and the air’s carbon dioxide by Fischer-Tropsch synthesis under the SOLETAIR project. Here, INERATEC, a spinoff of Karlsruhe Institute of Technology (KIT), cooperates with Finnish partners...

A Papertronic, On-Demand and Disposable Biobattery: Saliva-Activated Electricity Generation from Lyophilized Exoelectrogens Preinoculated on Paper. Advanced Materials Technologies, 2017; 1700127 DOI: 10.1002/admt.201700127

Researchers have developed the next step in microbial fuel cells (MFCs): a battery activated by spit that can be used in extreme conditions where normal batteries don’t function. Researchers at Binghamton University, State University of New York have developed the next step in microbial fuel cells (MFCs): a battery activated by spit that can be used in extreme conditions where normal batteries don’t function.

For the last 5 years, Binghamton University Electrical and Computer Science Assistant Professor Seokheun Choi has focused on developing micro-power sources for the ...

Terahertz radiation—the band of the electromagnetic spectrum between microwaves and visible light—has promising applications in medical and industrial imaging and chemical detection, among other uses. But many of those applications depend on small, power-efficient sources of terahertz rays, and the standard method for producing them involves a bulky, power-hungry, tabletop device. For over 20 years, Prof. Qing Hu at MIT, and his group have been working on sources of terahertz radiation that can be etched onto microchips...
