Published A recipe for zero-emissions fuel: Soda cans, seawater, and caffeine
(via sciencedaily.com) Original source Engineers discovered that when the aluminum in soda cans is purified and mixed with seawater, the solution produces hydrogen -- which can power an engine or fuel cell without generating carbon emissions. The reaction can be sped up by adding caffeine.
Published Scientists study how to bring you 'climate-smart coffee'
(via sciencedaily.com) Original source Coffee beans consumed across the globe come from two species: Coffea arabica and Coffea canephora. By 2050, about 80% of Arabica production is predicted to decrease because of climate change. Researchers are investigating to see if they can find alternative coffee cultivars.
Published Better way to produce green hydrogen
(via sciencedaily.com) Original source Researchers have developed a material that shows a remarkable ability to convert sunlight and water into clean energy.
Published Raindrops grow with turbulence in clouds
(via sciencedaily.com) Original source Tackling a long-time mystery, scientists have found that the turbulent movements of air in clouds play a key role in the growth of water droplets and the initiation of rain. The research can improve computer model simulations of weather and climate and ultimately lead to better forecasts.
Published Parched Central Valley farms depend on Sierras for groundwater
(via sciencedaily.com) Original source New research shows California's Central Valley, known as America's breadbasket, gets as much as half of its groundwater from the Sierra Nevadas. This is significant for a farming region that, in some parts, relies almost entirely on groundwater for irrigation.
Published Seven steps to achieving the right to clean indoor air post-pandemic
(via sciencedaily.com) Original source Seven lessons learned from the COVID-19 pandemic about ventilation's crucial role in preventing the spread of airborne pathogens has been set out in a new article.
Published Researchers develop innovative battery recycling method
(via sciencedaily.com) Original source A research team is tackling the environmental issue of efficiently recycling lithium ion batteries amid their increasing use.
Published Waters along Bar Harbor, Acadia home to billions of microplastics
(via sciencedaily.com) Original source Researchers reveal there are an estimated 400 billion microplastic fibers on the surface of Frenchman Bay, which borders Bar Harbor and Acadia National Park in Maine, and several connected rivers and estuaries where freshwater from rivers meet salty seawater. The watershed contains an average of 1.8 fibers per liter of water. The team also investigated how microplastics traveled throughout the watershed by sampling water from nine sites on Mount Desert Island, particularly within Bar Harbor.
Published How Saharan dust regulates hurricane rainfall
(via sciencedaily.com) Original source New research underscores the close relationship between dust plumes transported from the Sahara Desert in Africa, and rainfall from tropical cyclones along the U.S. Gulf Coast and Florida.
Published Researchers record images and data of a shark experiencing a boat strike
(via sciencedaily.com) Original source Researchers have captured what they believe is the first ever video of a shark or any large marine animal being struck by a boat.
Published Drawing water from dry air
(via sciencedaily.com) Original source A prototype device harvests drinking water from the atmosphere, even in arid places.
Published Better carbon storage with stacked geology
(via sciencedaily.com) Original source According to new research subsurface reservoirs that are covered by a collection of hundreds of smaller lids -- collectively called a 'composite confining system' -- may be the better option for keeping carbon trapped for the long term. That's good news for the carbon storage industry. This type of distributed system is common in a range of geological environments.
Published Researchers develop more environmentally friendly and cost-effective method for soil remediation
(via sciencedaily.com) Original source Chemists have developed a rapid electrothermal mineralization (REM) process, which in seconds can remediate the accumulation of synthetic chemicals that can contaminate soil and the environment.
Published A promising new method uses light to clean up forever chemicals
(via sciencedaily.com) Original source A room-temperature method to decompose perfluoroalkyl substances (PFASs) using visible LED light offers a promising solution for sustainable fluorine recycling and PFAS treatment.
Published Converting captured carbon to fuel: Study assesses what's practical and what's not
(via sciencedaily.com) Original source A new analysis sheds light on major shortfalls of a recently proposed approach to capture CO2 from air and directly convert it to fuel using electricity. The authors also provide a new, more sustainable, alternative.
Published Team develops safe and long-cyclable lithium metal battery for high temperatures
(via sciencedaily.com) Original source In recent years, batteries have become ubiquitous in consumers' daily lives. However, existing commercial battery technologies, which use liquid electrolytes and carbonaceous anodes, have certain drawbacks such as safety concerns, limited lifespan, and inadequate power density particularly at high temperatures.
Published Ecologists discover rare fiddler crab species on Hong Kong coast highlighting the impact of climate change and coastal development
(via sciencedaily.com) Original source Researchers have made an exciting discovery on the Hong Kong coast. They have identified two fiddler crab species: Tubuca dussumieri, previously recorded in old literature but never confirmed in recent times, and Tubuca. coarctata, which has never been seen in Hong Kong. These findings not only confirm the presence of these insular species in Hong Kong but also explore the potential impact of climate change on their distribution.
Published Maximizing hydrogen peroxide formation during water electrolysis
(via sciencedaily.com) Original source When water is split electrolytically, the result is typically hydrogen -- and 'useless' oxygen. Instead of oxygen, you can also produce hydrogen peroxide, which is required for many branches of industry. This, however, requires certain reaction conditions.
Published Fish adjust reproduction in response to predators
(via sciencedaily.com) Original source Some species of fish can evolve their egg-laying habits in response to predators in the area in order to survive, according to new research.
Published New humidity-driven membrane to remove carbon dioxide from the air
(via sciencedaily.com) Original source A new ambient-energy-driven membrane that pumps carbon dioxide out of the air has been developed by researchers.
