Published Could lead overcome reverse current and advance a green hydrogen economy?
(via sciencedaily.com) Original source Researchers developed a catalyst that enhances the stability of alkaline water electrolysis systems.
Published New study provides enhanced understanding of tropical atmospheric waves
(via sciencedaily.com) Original source Findings has critical implications for predicting extreme weather events such as hurricanes and heavy rainfall.
Published High-speed electron camera uncovers a new 'light-twisting' behavior in an ultrathin material
(via sciencedaily.com) Original source Using an instrument for ultrafast electron diffraction (MeV-UED), researchers discovered how an ultrathin material can circularly polarize light. This discovery sets up a promising approach to manipulate light for applications in optoelectronic devices.
Published Planted mangroves' ability to store carbon
(via sciencedaily.com) Original source Ecologists have published new findings on how planted mangroves can store up to 70% of carbon stock to that found in intact stands after only 20 years.
Published Mozambican Woodlands could store more than double the carbon previously estimated
(via sciencedaily.com) Original source The capacity of Mozambican woodlands to capture and store carbon is underestimated and potentially undervalued for their protection and restoration, finds new research from an international team of scientists.
Published Wolves' return has had only small impact on deer populations in NE Washington
(via sciencedaily.com) Original source Wolves returned to Washington state in 2008. A new study shows that, despite their rising numbers, wolves are not having much of an impact on white-tailed deer, one of their primary prey. Scientists report that the biggest factor shaping white-tailed deer populations in northeast Washington is the quality of habitat available, which is largely determined by human activity. Cougars were second in their impact. Wolves were a distant third.
Published Enhancing live football broadcasts by eliminating camera operator distractions with AI
(via sciencedaily.com) Original source Researchers have developed an end-to-end system to enhance the viewing experience by eliminating visual distractions caused by overlapping camera angles.
Published New period product offers progress in women's health
(via sciencedaily.com) Original source Researchers have created an eco-friendly, blood absorbent biomaterial that improves the performance of menstrual products by minimizing blood leakage and spilling, while also helping prevent infection.
Published The Gulf Stream is wind-powered and could weaken from climate change
(via sciencedaily.com) Original source New evidence of changes to the Gulf Stream during the last ice age could indicate additional sensitivity to future climatic changes, finds a new study.
Published BESSY II shows how solid-state batteries degrade
(via sciencedaily.com) Original source Solid-state batteries have several advantages: they can store more energy and are safer than batteries with liquid electrolytes. However, they do not last as long and their capacity decreases with each charge cycle. But it doesn't have to stay that way: Researchers are already on the trail of the causes.
Published Researchers show promising material for solar energy gets its curious boost from entropy
(via sciencedaily.com) Original source Researchers discovered a microscopic mechanism that solves in part the outstanding performance achieved by a new class of organic semiconductors known as non-fullerene acceptors (NFAs).
Published Cutting farm nitrous oxide emissions helps climate and ozone layer
(via sciencedaily.com) Original source Adding crushed basalt rocks and special fertilizers can reduce potent nitrous oxide (N2O) greenhouse gas emissions and help safeguard the stratospheric ozone layer.
Published Researchers examine economic effects on technological advancements of blue hydrogen production
(via sciencedaily.com) Original source Experience from the deployment of blue hydrogen projects will be helpful in lowering future costs of hydrogen production and will remain cost competitive. Additionally, paired with extended tax incentives for carbon sequestration, costs could be significantly reduced further.
Published Moving from the visible to the infrared: Developing high quality nanocrystals
(via sciencedaily.com) Original source Awarded the 2023 Nobel Prize in Chemistry, quantum dots have a wide variety of applications ranging from displays and LED lights to chemical reaction catalysis and bioimaging. These semiconductor nanocrystals are so small -- on the order of nanometers -- that their properties, such as color, are size dependent, and they start to exhibit quantum properties. This technology has been really well developed, but only in the visible spectrum, leaving untapped opportunities for technologies in both the ultraviolet and infrared regions of the electromagnetic spectrum.
Published First local extinction in the US due to sea level rise, study suggests
(via sciencedaily.com) Original source The United States has lost its only stand of the massive Key Largo tree cactus in what researchers believe is the first local extinction of a species caused by sea level rise in the country.
Published Pinpointing coal plants to convert to nuclear energy, considering both practicality and community support
(via sciencedaily.com) Original source An assessment ranks the feasibility of converting 245 operational coal power plants in the U.S. into advanced nuclear reactors, providing valuable insights for policymakers and utilities to meet decarbonization goals, according to a new study.
Published Groundbreaking study reveals oceanic seabirds chase tropical cyclones
(via sciencedaily.com) Original source A new study reveals that the rare Desertas Petrels (Pterodroma deserta), a wide-ranging seabird in the North Atlantic, exhibit unique foraging behaviors during hurricane season. Contrary to other pelagic seabirds, these petrels do not avoid intense tropical cyclones but instead exploit the dynamic conditions for their benefit, providing new insights into the impact of cyclones on open ocean marine life.
Published Mining rare earth metals from electronic waste
(via sciencedaily.com) Original source A small molecule that naturally serves as a binding site for metals in enzymes also proves useful for separating certain rare earth metals from each other. In a proof of concept, the process extracts europium directly from fluorescent powder in used energy-saving lamps in much higher quantities than existing methods. The researchers are now working on expanding their approach to other rare earth metals. They are in the process of founding a start-up to put the recycling of these raw materials into practice.
Published It takes a cool microscope and antifreeze to really look at ice
(via sciencedaily.com) Original source Ice in nature is surrounded by liquid most of the time, and therefore it is key to understand how ice and liquid interact. A new study has now directly observe the precise shape of ice at the interface between ice and liquid -- by using antifreeze and a refrigerated microscope.
Published Engine wear risk as planes swallow more dust waiting to land
(via sciencedaily.com) Original source Planes flying into one of the world's busiest airports are ingesting around 10kg of dust per 1,000 flights.
