Published Plate tectonics not required for the emergence of life
(via sciencedaily.com)
Original source 
New finding contradicts previous assumptions about the role of mobile plate tectonics in the development of life on Earth. Moreover, the data suggests that 'when we're looking for exoplanets that harbor life, the planets do not necessarily need to have plate tectonics,' says the lead author of a new paper.
Published Study explains unusual deformation in Earth's largest continental rift
(via sciencedaily.com)
Original source 
Computer models confirm that the African Superplume is responsible for the unusual deformations, as well as rift-parallel seismic anisotropy observed beneath the East African Rift System.
Published All-electric rideshare fleet could reduce carbon emissions, increase traffic issues
(via sciencedaily.com)
Original source 
Two major ridesharing companies have promised all-electric fleets by 2030 in an effort to reduce their carbon footprint. To understand additional impacts of this transition, researchers conducted life-cycle comparisons of battery-powered electric vehicle fleets to a gas-powered one, using real-world rideshare data. They found up to a 45% reduction in greenhouse gas emissions from full electrification; however, traffic problems and air pollution could increase.
Published Novel ferroelectrics for more efficient microelectronics
(via sciencedaily.com)
Original source 
A team of researchers is exploring novel materials that have potential to make microelectronics more energy efficient. Their recent work explores recently discovered wurtzite ferroelectrics, which are mainly composed of materials that are already incorporated in semiconductor technology for integrated circuits. These materials allow for the integration of new power-efficient devices for applications such as non-volatile memory, electro-optics, and energy harvesting.
Published Megawatt electrical motor designed by engineers could help electrify aviation
(via sciencedaily.com)
Original source 
Aerospace engineers designed a 1-megawatt electrical motor that is a stepping stone toward electrifying the largest aircraft.
Published Campi Flegrei volcano edges closer to possible eruption
(via sciencedaily.com)
Original source 
The new study used a model of volcano fracturing to interpret patterns of earthquakes and ground uplift, and concluded that parts of the volcano had been stretched nearly to breaking point.
Published Bubble, bubble, more earthquake trouble? Geoscientists study Alaska's Denali fault
(via sciencedaily.com)
Original source 
Geochemists report findings from collected and analyzed helium and carbon isotopic data from springs along a nearly 250-mile segment of Alaska's Denali Fault. The fault's mantle fluid flow rates, they report, fall in the range observed for the world's other major and active strike-slip faults that form plate boundaries.
Published New superconducting diode could improve performance of quantum computers and artificial intelligence
(via sciencedaily.com)
Original source 
A team has developed a more energy-efficient, tunable superconducting diode -- a promising component for future electronic devices -- that could help scale up quantum computers for industry and improve artificial intelligence systems.
Published Flexible nanoelectrodes can provide fine-grained brain stimulation

Original source 
Engineers have developed ultraflexible implantable nanoelectrodes that can administer long-term, fine-grained brain stimulation.
Published New catalyst lowers cost for producing environmentally sustainable hydrogen from water
(via sciencedaily.com)
Original source 
A team has developed a new catalyst composed of elements abundant in the Earth. It could make possible the low-cost and energy-efficient production of hydrogen for use in transportation and industrial applications.
Published The next generation of solar energy collectors could be rocks
(via sciencedaily.com)
Original source 
The next generation of sustainable energy technology might be built from some low-tech materials: rocks and the sun. Using a new approach known as concentrated solar power, heat from the sun is stored then used to dry foods or create electricity. A team has found that certain soapstone and granite samples from Tanzania are well suited for storing this solar heat, featuring high energy densities and stability even at high temperatures.
Published Hidden in plain sight: Windshield washer fluid is an unexpected emission source
(via sciencedaily.com)
Original source 
Exhaust fumes probably come to mind when considering vehicle emissions, but they aren't the only source of pollutants released by a daily commute. Researchers report that alcohols in windshield washer fluid account for a larger fraction of real-world vehicle emissions than previous estimates have suggested. Notably, the levels of these non-fuel-derived gases will likely remain unchanged, even as more drivers transition from gas-powered to electric vehicles.
Published Absolute vs. relative efficiency: How efficient are blue LEDs, actually?
(via sciencedaily.com)
Original source 
The absolute internal quantum efficiency (IQE) of indium gallium nitride (InGaN) based blue light-emitting diodes (LEDs) at low temperatures is often assumed to be 100%. However, a new study has found that the assumption of always perfect IQE is wrong: the IQE of an LED can be as low as 27.5%.
Published Hydrogen battery: Storing hydrogen in coal may help power clean energy economy
(via sciencedaily.com)
Original source 
The quest to develop hydrogen as a clean energy source that could curb our dependence on fossil fuels may lead to an unexpected place -- coal. Scientists have found that coal may represent a potential way to store hydrogen gas, much like batteries store energy for future use, addressing a major hurdle in developing a clean energy supply chain.

Original source 
To overcome global energy challenges and fight the looming environmental crisis, researchers around the world investigate new materials for converting sunlight into electricity. Some of the most promising candidates for high-efficiency low-cost solar cell applications are based on lead halide perovskite (LHP) semiconductors. Despite record-breaking solar cell prototypes, the microscopic origin of the surprisingly excellent optoelectronic performance of this material class is still not completely understood. Now, an international team of physicists and chemists has demonstrated laser-driven control of fundamental motions of the LHP atomic lattice.
