Self-sustaining microbial fuel cell Researchers at Binghamton University developed the first micro-scale self-sustaining microbial fuel cell, which generates power through the symbiotic interactions of two types of bacteria. A mixed culture of phototrophic and heterotrophic bacteria were placed in a 90-microliter cell chamber, or about one-fifth the size of a teaspoon. Phototrophic bacter... » read more

Storing solar energy as carbon monoxide A team at Indiana University engineered a molecule that collects and stores solar energy without solar panels. The molecule uses light or electricity to convert the greenhouse gas carbon dioxide into carbon monoxide more efficiently than any other method of carbon reduction. Burning fuel such as carbon monoxide produces carbon dioxide and releases e... » read more

Tiny redox flow batteries for chips Researchers at ETH Zurich and IBM Research Zurich built a tiny redox flow battery capable of both powering and cooling stacks of chips. In a flow battery, an electrochemical reaction is used to produce electricity out of two liquid electrolytes, which are pumped to the battery cell from outside via a closed electrolyte loop. Such batteries are usually u... » read more

Magnetic storage on one atom Scientists at IBM Research created a single-atom magnet and were able to store one bit of data on it, making it the world's smallest magnetic storage device. Using electrical current, the researchers showed that two magnetic atoms could be written and read independently even when they were separated by just one nanometer. This tight spacing could, the team hop... » read more

Supercapacitor plants Scientists at Linköping University in Sweden developed a method for transforming roses into supercapacitors that can be charged and discharged hundreds of times. The team created a solution that, when fed through the cut end of the stem, polymerizes inside the rose's vascular system with the plant's own biochemical response mechanism acting as catalyst, creating lon... » read more

Harvesting energy from multiple sources Researchers from the University of Oulu in Finland found a particular type of perovskite, KBNNO, has the right properties to extract energy from multiple sources simultaneously. While perovskites are particularly known for their use as solar cells, certain minerals in the perovskite family show piezoelectric and pyroelectric (harvesting energy from ... » read more

Electronics for Venus A team of scientists at NASA's Glenn Research Center in Cleveland demonstrated the first prolonged operation of electronics in the harsh conditions found on Venus. Current Venus landers can only operate on the planet's surface for a few hours due to the extreme atmospheric conditions. The surface temperature on Venus is nearly 860 degrees Fahrenheit, and the planet h... » read more

Microbial nanowires Microbiologists at the University of Massachusetts Amherst report that they have discovered a new type of microbial nanowire, the protein filaments that bacteria use to make electrical connections with other microbes or minerals. The team was motivated by the potential for improved "green" conducting materials for electronics. According to Derek Lovley, professor of... » read more
