Published Key to improved green tech efficiency found in simple acid treatment
(via sciencedaily.com) The development of new, more efficient electrochemical cells could provide a good option for carbon-free hydrogen and chemical production along with large-scale electricity generation and storage. But first, scientists must overcome several challenges, including how to make the cells more efficient and cost-effective.
Published Why Venus rotates, slowly, despite sun's powerful grip
(via sciencedaily.com) If not for the soupy, fast-moving atmosphere on Venus, Earth's sister planet would likely not rotate. Instead, Venus would be locked in place, always facing the sun the way the same side of the moon always faces Earth.
Published Jupiter's moon has splendid dunes
(via sciencedaily.com) Scientists have long wondered how Jupiter's innermost moon, Io, has meandering ridges as grand as any that can be seen in movies like 'Dune.' Now, a research study has provided a new explanation of how dunes can form even on a surface as icy and roiling as Io's.
Published Extract from a common kitchen spice could be key to greener, more efficient fuel cells
(via sciencedaily.com) Researchers have discovered a novel way to combine curcumin -- the substance in turmeric -- and gold nanoparticles to create an electrode that requires 100 times less energy to efficiently convert ethanol into electricity.
Published You've heard of water droughts. Could 'energy' droughts be next?
(via sciencedaily.com) Drawing on 70 years of historic wind and solar-power data, researchers built an AI model to predict the probability of a network-scale 'drought,' when daily production of renewables fell below a target threshold. Under a threshold set at the 30th percentile, when roughly a third of all days are low-production days, the researchers found that Texas could face a daily energy drought for up to four months straight. Batteries would be unable to compensate for a drought of this length, and if the system relied on solar energy alone, the drought could be expected to last twice as long -- for eight months.
Published Lack of marshaling ports hindering offshore wind industry
(via sciencedaily.com) A new study finds that the nation's existing and planned marshaling ports, the assembly areas critical to building and deploying offshore wind turbines, will be insufficient by 2023 to meet commitments and will fail to meet projected demand through 2050.
Published Collision hotspots for migrating birds revealed in new study
(via sciencedaily.com) New research highlights the areas in Europe and North Africa where the construction of wind turbines or power lines is likely to increase the risk of death for migrating birds.
Published Neptune is cooler than we thought: Study reveals unexpected changes in atmospheric temperatures
(via sciencedaily.com) New research has revealed how temperatures in Neptune's atmosphere have unexpectedly fluctuated over the past two decades.
Published Differences between the Moon’s near and far sides linked to colossal ancient impact
(via sciencedaily.com) New research shows how the impact that created the Moon's South Pole -- Aitken basin is linked to the stark contrast in composition and appearance between the two sides of the Moon.
Published Arctic simulation of Moon-like habitat shows wellbeing sessions can improve mental health in extreme isolation
(via sciencedaily.com) Researchers are investigating the psychological impact of social isolation in harsh environments, such as on the Moon.
Published 'Ears' for rover Perseverance's exploration of Mars
(via sciencedaily.com) Scientists have built instruments to give humans eyes and a nose on Mars -- and now they are helping add ears as well.
Published Scientists connect the dots between Galilean moon, auroral emissions on Jupiter
(via sciencedaily.com) On November 8, 2020, NASA's Juno spacecraft flew through an intense beam of electrons traveling from Ganymede, Jupiter's largest moon, to its auroral footprint on the gas giant. Scientists used data from Juno's payload to study the particle population traveling along the magnetic field line connecting Ganymede to Jupiter while, at the same time, remotely sensing the associated auroral emissions to unveil the mysterious processes creating the shimmering lights.
Published 'Prenatal' protoplanet upends planet formation models
(via sciencedaily.com) An international research team has discovered a new planet so young that it has yet to emerge from the womb of matter where it is forming. This is the youngest protoplanet discovered to date. It's location and the surrounding patterns of matter suggest that an alternative method of planet formation may be at work. This discovery could help to explain the histories and features of extrasolar planets seen around other stars.
Published Perseverance records the first ever sounds from Mars
(via sciencedaily.com) NASA's Perseverance rover, which has been surveying the surface of Mars since February 2021, has for the first time recorded the acoustic environment of the Red Planet.
Published Mercury has magnetic storms
(via sciencedaily.com) An international team of scientists has proved that Mercury, our solar system's smallest planet, has geomagnetic storms similar to those on Earth. Their finding, a first, answers the question of whether other planets, including those outside our solar system, can have geomagnetic storms regardless of the size of their magnetosphere or whether they have an Earth-like ionosphere.
Published Scavenger nanoparticles could make fuel cell-powered vehicles a reality
(via sciencedaily.com) Engineers have developed a material that could give fuel cell systems a competitive edge over the battery systems that currently power most electric vehicles.
Published New method purifies hydrogen from heavy carbon monoxide mixtures
(via sciencedaily.com) Refining metals, manufacturing fertilizers and powering fuel cells for heavy vehicles are all processes that require purified hydrogen. But purifying, or separating, that hydrogen from a mix of other gases can be difficult, with several steps. Chemical engineers have now demonstrated that the process can be simplified using a pump outfitted with newly developed membrane materials.
Published Mounds of ice in craters give new insight into Mars’ past climate
(via sciencedaily.com) Newly discovered deposits of layered ice in craters scattered around Mars' southern hemisphere provide insights into how the planet's orientation controlled the planet's climate over the past 4 million years, according to a new study. The findings help scientists understand what controlled Mars' past climate, which is essential for predicting when the planet could have been habitable.
Published Fuel from waste wood
(via sciencedaily.com) According to the latest assessment report from the Intergovernmental Panel on Climate Change, a considerable reduction in CO2 emissions is required to limit the consequences of climate change. Producing fuel from renewable sources such as waste wood and straw or renewable electricity would be one way to reduce carbon emissions from the area of transportation.
Published Carbon-coated nickel enables fuel cell free of precious metals
(via sciencedaily.com) A nitrogen doped carbon-coated nickel anode can catalyze an essential reaction in hydrogen fuel cells at a fraction of the cost of the precious metals currently used, researchers have found.
