Power Generation by Biofuel Cell

Authors: George Rajna

Researchers have developed the first fully functional biofuel cell whose biocatalysts (enzymes that play a critical role in power generation) directly self-assemble onto the electrodes. [42] Researchers have developed a faster, cheaper and simpler alternative to typical DNA origami fabrication, increasing the technique's accessibility and potential impact in industry and clinical settings. [41] Two physicists working out of the University of Florida and Pacific Northwest National Laboratory, Paul Johns and Juan Nino, conducted research to enhance global nuclear security by improving radiation detectors. [40] Hybrid organic-inorganic perovskites are especially successful, and they have been used in optoelectronic devices including solar cells, photodetectors, light-emitting diodes and lasers. [39] A new microscope breaks a long-standing speed limit, recording footage of brain activity 15 times faster than scientists once believed possible. [38] Engineers at Duke University have developed a method for extracting a color image from a single exposure of light scattered through a mostly opaque material. [37] Physicists from Nanyang Technological University, Singapore (NTU Singapore) and the Niels Bohr Institute in Copenhagen, Denmark, have devised a method to turn a non-magnetic metal into a magnet using laser light. [36] Physicists at EPFL propose a new "quantum simulator": a laser-based device that can be used to study a wide range of quantum systems. [35] The DESY accelerator facility in Hamburg, Germany, goes on for miles to host a particle making kilometer-long laps at almost the speed of light. Now researchers have shrunk such a facility to the size of a computer chip. [34] University of Michigan physicists have led the development of a device the size of a match head that can bend light inside a crystal to generate synchrotron radiation in a lab. [33] A new advance by researchers at MIT could make it possible to produce tiny spectrometers that are just as accurate and powerful but could be mass produced using standard chip-making processes.
