Published Chameleon-inspired coating could cool and warm buildings through the seasons
(via sciencedaily.com) As summer turns to fall, many people will be turning off the air conditioning and firing up heaters instead. But traditional heating and cooling systems are energy intensive, and because they typically run on fossil fuels, they aren't sustainable. Now, by mimicking a desert-dwelling chameleon, a team has developed an energy-efficient, cost-effective coating. The material could keep buildings cool in the summers -- or warm in the winters -- without additional energy.
Published New Si-based photocatalyst enables efficient solar-driven hydrogen production and biomass refinery
(via sciencedaily.com) A research team has achieved a significant breakthrough in the development of a hybrid silicon photocatalyst.
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 Tall buildings could be built quicker if damping models were correct, study finds
(via sciencedaily.com) Multi-story buildings are assembled over-cautiously to withstand wind strengths, researchers have found.
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 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 Step change in upconversion the key to clean water, green energy and futuristic medicine
(via sciencedaily.com) Achieving photochemical upconversion in a solid state is a step closer to reality, thanks to a new technique that could unlock vital innovations in renewable energy, water purification and advanced healthcare.
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 Making hydrogen from waste plastic could pay for itself
(via sciencedaily.com) Researchers have found a way to harvest hydrogen from plastic waste using a low-emissions method that generates graphene as a by-product, which could help offset production costs.
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.
Published Studies highlight new approaches to addressing climate change
(via sciencedaily.com) Original source Failing to achieve climate mitigation goals puts increasing pressure on climate adaptation strategies. In two new studies, researchers address novel approaches to these issues.
Published New ionic materials boost hydrogen fuel cell efficiency!
(via sciencedaily.com) A research team has made a groundbreaking advancement in improving the efficiency of hydrogen fuel cells, which are gaining significant attention as eco-friendly next-generation energy sources.
Published Scientists develop new method to recover high-purity silicon from expired solar panels for upcycling into lithium-ion batteries
(via sciencedaily.com) Scientists have devised an efficient method of recovering high-purity silicon from expired solar panels to produce lithium-ion batteries that could help meet the increasing global demand to power electric vehicles.
