Lithium-iron-oxide battery Scientists at Northwestern University and Argonne National Laboratory developed a rechargeable lithium-iron-oxide battery that can cycle more lithium ions than its common lithium-cobalt-oxide counterpart, leading to a much higher capacity. For their battery, the team not only replaced cobalt with iron, but forced oxygen to participate in the reaction process as we... » read more

Eel-inspired power Researchers at the University of Michigan, the University of Fribourg, and the University of California-San Diego developed soft power cells with the potential to power implanted medical devices. Made of hydrogel and salt, the soft cells form the first potentially biocompatible artificial electric organ that generates more than 100 volts at a low current, the team says, enou... » read more

Hydrogen from seawater Engineers at Columbia University are developing an ocean-based photovoltaic-powered electrolysis device that can operate as a stand-alone floating platform to split water into hydrogen fuel and oxygen. State-of-the-art electrolyzers use expensive membranes to maintain separation of the H2 and O2 gases produced by water electrolysis. The new device relies instead on an... » read more

Stabilizing perovskites Scientists at EPFL and the University of Cordoba found a way to improve the stability of perovskite solar cells. While perovskites show promising efficiencies as solar cells, they are soft crystalline materials and prone to problems due to decomposition over time. By introducing the large organic cation guanidinium (CH6N3+) into methylammonium lead iodide perovskites, t... » read more

Solar jet fuel Researchers at ETH Zurich demonstrated the ability to use solar energy to create the precursor to jet fuel from water and carbon dioxide, a process that could lead to carbon-neutral air travel. The scientists performed 295 consecutive cycles in a 4 kW solar reactor, yielding 700 standard liters of hydrogen and carbon monoxide (syngas), the precursor to kerosene and other liqu... » read more

Deep learning to detect nuclear reactor cracks Inspecting nuclear power plant components for cracks is critical to preventing leaks, as well as to control in maintenance costs. But the current vision-based crack detection approaches are not very effective. Moreover, they are prone to human error, which in the case of nuclear power can be disastrous. To address this problem, Purdue Universit... » read more

Greener greenhouses Researchers at the University of California, Santa Cruz are testing greenhouses capable of generating some of their own energy, without hampering plant growth. Greenhouses use electricity to control temperature and power fans, lights, and other monitoring systems. Electricity-generating solar greenhouses utilize Wavelength-Selective Photovoltaic Systems (WSPVs), a novel ... » read more

Bacteria power wastewater cleanup Researchers at the King Abdullah University of Science and Technology (KAUST) are exploring ways to detoxify warm, salty industrial wastewater while simultaneously generating electricity. They are using bacteria with remarkable properties: the ability to transfer electrons outside their cells (exoelectrogenes) and the capacity to withstand extremes of temperat... » read more

Speeding up MRAM Researchers at UC Berkeley and UC Riverside developed an ultrafast method for electrically controlling magnetism in certain metals, which could lead to increased performance for magnetic RAM. While the nonvolatility of MRAM is a boon, speeding up the writing of a single bit of information to less than 10 nanoseconds has been a challenge. “The development of a non-volatile... » read more
