Published Efficient next-generation solar panels on horizon following breakthrough
(via sciencedaily.com) A scientific breakthrough brings mass production of the next generation of cheaper and lighter perovskite solar cells one step closer.
Published New research brings greater understanding of Asian winter monsoon
(via sciencedaily.com) Original source Scientists have discovered a new technique which will shed light on the phenomena of winter monsoons -- the heavy autumn and winter rainfalls which can cause floods and landslides across southeast Asia.
Published Electrons take flight at the nanoscale
(via sciencedaily.com) A study showing how electrons flow around sharp bends, such as those found in integrated circuits, has the potential to improve how these circuits, commonly used in electronic and optoelectronic devices, are designed.
Published Combustion powers bug-sized robots to leap, lift and race
(via sciencedaily.com) Researchers combined soft microactuators with high-energy-density chemical fuel to create an insect-scale quadrupedal robot that is powered by combustion and can outrace, outlift, outflex and outleap its electric-driven competitors.
Published Cheap and efficient catalyst could boost renewable energy storage
(via sciencedaily.com) Storing renewable energy as hydrogen could soon become much easier thanks to a new catalyst based on single atoms of platinum.
Published Engineers grow full wafers of high-performing 2D semiconductor that integrates with state-of-the-art chips
(via sciencedaily.com) Researchers have grown a high-performing 2D semiconductor to a full-size, industrial-scale wafer. In addition, the semiconductor material, indium selenide (InSe), can be deposited at temperatures low enough to integrate with a silicon chip.
Published How wind turbines react to turbulence
(via sciencedaily.com) The output of wind turbines can rise or fall by 50 per cent in a matter of seconds. Such fluctuations in the megawatt range put a strain on both power grids and the turbines themselves. A new study presents a new stochastic method that could help to mitigate these sudden swings and achieve a more consistent electricity production.
Published Predictive model could improve hydrogen station availability
(via sciencedaily.com) Consumer confidence in driving hydrogen-fueled vehicles could be improved by having station operators adopt a predictive model that helps them anticipate maintenance needs, according to researchers.
Published Golden future for thermoelectrics
(via sciencedaily.com) Researchers discover excellent thermoelectric properties of nickel-gold alloys. These can be used to efficiently convert heat into electrical energy.
Published Pearl Harbor: Bombed battleships' boost for climate science
(via sciencedaily.com) Original source A new research paper tells the story of the recovery of World War II weather data from 19 US Navy ships thanks to the hard work of over 4,000 volunteers.
Published Researchers make strides in harnessing low-grade heat for efficient energy conversion
(via sciencedaily.com) A research team has achieved significant breakthroughs in harnessing low-grade heat sources (<100 °C) for efficient energy conversion.
Published Battery-free robots use origami to change shape in mid-air
(via sciencedaily.com) Researchers have developed small robotic devices that can change how they move through the air by 'snapping' into a folded position during their descent. Each device has an onboard battery-free actuator, a solar power-harvesting circuit and controller to trigger these shape changes in mid-air.
Published Electrifying vehicles in Chicago would save lives, reduce pollution inequities
(via sciencedaily.com) If the Chicago region replaced 30% of all on-road combustion-engine vehicles -- including motorcycles, passenger cars and trucks, buses, refuse trucks and short- and long-haul trucks -- with electric versions, it would annually save more than 1,000 lives and over $10 billion, according to a new study.
Published Ohio's droughts are worse than often recognized, study finds
(via sciencedaily.com) Original source A new type of analysis suggests that droughts in Ohio were more severe from 2000 to 2019 than standard measurements have suggested.
Published Largest historic fire death toll belongs to aftermath of 1923 Japan Earthquake
(via sciencedaily.com) Original source Fires that raged in the days following the 1 September 1923 magnitude 7.9 Kant earthquake killed roughly 90% of the 105,000 people who perished in and around Tokyo, making it one of the deadliest natural disasters in history -- comparable to the number of people killed in the World War II atomic bombing of Hiroshima. The story of the conflagration, not well-known outside of Japan, holds important lessons for earthquake scientists, emergency response teams and city planners, according to a new article.
Published New super-fast flood model has potentially life-saving benefits
(via sciencedaily.com) Researchers have developed a new simulation model, which can predict flooding during an ongoing disaster more quickly and accurately than currently possible.
Published Climate change is reducing global river water quality
(via sciencedaily.com) Original source A review of almost 1000 studies on the effects of climate change and extreme weather events on rivers around the world has found an overall negative effect on water quality in rivers globally. An international team of experts sourced from every continent, conducted between 2000-2022.
Published Fewer but more intense tropical storms predicted over the Ganges and Mekong
(via sciencedaily.com) Original source Climate experts project a decline in the frequency of future tropical storms but an increase in their strength across the Ganges and Mekong basins allowing for better future planning.
Published Fall snow levels can predict a season's total snowpack in some western states
(via sciencedaily.com) Original source Research found that, in some western states, the amount of snow already on the ground by the end of December is a good predictor of how much total snow that area will get.
Published Hot summer air turns into drinking water with new gel device
(via sciencedaily.com) Researchers have focused on the moisture present in the air as a potential source of drinking water for drought-stressed populations. They reached a significant breakthrough in their efforts to create drinkable water out of thin air: a molecularly engineered hydrogel that can create clean water using just the energy from sunlight.
