Published Discovery of crucial clue to accelerate development of carbon-neutral porous materials
(via sciencedaily.com) Original source A recent study has provided a library of those various molecular clusters for future metal building blocks of MOFs, and suggested practical synthetic strategies.
Published Strong ultralight material could aid energy storage, carbon capture
(via sciencedaily.com) Original source Materials scientists showed that fine-tuning interlayer interactions in a class of 2D polymers can determine the materials' loss or retention of desirable mechanical properties in multilayer or bulk form.
Published Rising temperatures alter 'missing link' of microbial processes, putting northern peatlands at risk
(via sciencedaily.com) Researchers show that rising temperatures in northern regions may damage peatlands: critical ecosystems for storing carbon from the atmosphere -- and could decouple vital processes in microbial support systems.
Published Wastewater more potent breeding ground for antibiotic resistance than previously known
(via sciencedaily.com) Wastewater is a more potent environment for antibiotic resistance to evolve than previously known. A study shows that wastewaters have unique characteristics, allowing resistance genes to start their journey from harmless bacteria to those that cause disease.
Published Path to net-zero carbon capture and storage may lead to ocean
(via sciencedaily.com) Engineering researchers have developed a novel way to capture carbon dioxide from the air and store it in the 'infinite sink' of the ocean. The approach uses an innovative copper-containing polymeric filter and essentially converts CO2 into sodium bicarbonate (aka baking soda) that can be released harmlessly into the ocean. This new hybrid material, or filter, is called DeCarbonHIX (i.e., decarbonization through hybrid ion exchange material). The research has demonstrated a 300 percent increase in the amount of carbon captured compared with existing direct air capture methods.
Published At the end of the dry season: CO2 pulses over Australia
(via sciencedaily.com) End-of-dry-season CO2 pulses recur each year in the atmosphere above the Australian continent, a discovery made by an international research team led by an environmental physicist. To investigate the carbon fluxes over Australia, the researchers studied atmospheric CO2 measurements. Their analyses show that CO2 emissions spike when heavy rain falls on dried-out soil, thus activating microorganisms in that soil.
Published How plants cope with the cold light of day -- and why it matters for future crops
(via sciencedaily.com) New research has discovered a cold 'coping' mechanism that is under the control of the plant biological clock and could offer solutions to breeding more resilience into crops less suited to cold climates.
Published Earth prefers to serve life in XXS and XXL sizes
(via sciencedaily.com) Life comes in all shapes in sizes, but some sizes are more popular than others, new research has found. A survey of body sizes of all Earth's living organisms has uncovered an unexpected pattern. Contrary to what current theories can explain, our planet's biomass -- the material that makes up all living organisms -- is concentrated in organisms at either end of the size spectrum.
Published Mimicking biological enzymes may be key to hydrogen fuel production
(via sciencedaily.com) An ancient biological enzyme known as nickel-iron hydrogenase may play a key role in producing hydrogen for a renewables-based energy economy, researchers said. Careful study of the enzyme has led chemists to design a synthetic molecule that mimics the hydrogen gas-producing chemical reaction performed by the enzyme.
Published Most of world's salt marshes likely to be underwater by 2100, study concludes
(via sciencedaily.com) Salt marshes are some of the most biologically productive ecosystems on Earth. They play an outsized role in nitrogen cycling, act as carbon sinks, protect coastal development from storm surge, and provide critical habitats and nurseries for many fish, shellfish, and coastal birds. According to new research, more than 90 percent of the world's salt marshes are likely to be underwater by the end of the century. These findings come from a 50-year study of ecosystem changes in Great Sippewissett Marsh in Falmouth, Mass.
Published Energy-efficient and customizable inorganic membranes for a cleaner future
(via sciencedaily.com) A team of researchers has developed a revolutionary technique for producing ultrathin inorganic membranes. These inorganic membranes are not just energy-efficient but also highly customizable for different applications, such as filtration, separation, energy conversion, catalysis and sensing. This ground-breaking achievement could potentially revolutionize the way many industries operate for greater sustainability.
Published Fermented coffee's fruity aromas demystified
(via sciencedaily.com) Fermented coffee could bring a fruity taste to your morning cup of joe. This new kind of beverage has a raspberry-like taste and aroma, but what causes these sensations has been a mystery. Scientists now report six compounds that contribute to the fermented coffee experience.
Published Three newly discovered sea worms that glow in the dark named after creatures from Japanese folklore and marine biologist
(via sciencedaily.com) Original source Researchers have discovered three new species of luminescent Polycirrus worms that emit blue-purple light. They named two of them after glowing creatures in Japanese folklore, and the other after the former director of Notojima Aquarium who helped find the worms.
Published Revolutionary battery technology to boost EV range 10-fold or more
(via sciencedaily.com) A team develops layering-charged, polymer-based stable high-capacity anode material.
Published New additives could turn concrete into an effective carbon sink
(via sciencedaily.com) Introducing additives to concrete manufacturing processes could reduce the sizeable carbon footprint of the material without altering its bulk mechanical properties, a study shows.
Published Conserving wildlife can help mitigate climate change
(via sciencedaily.com) Solving the climate crisis and biodiversity crisis are not separate issues. Animals remove billions of tons of carbon dioxide each year. Restoring species will help limit global warming, new science reveals.
Published Eco-efficient cement could pave the way to a greener future
(via sciencedaily.com) Scientists develop process to remove toxic heavy metals from coal fly ash, making for greener, stronger concrete.
Published Team uses natural catalysts to develop low-cost way of producing green hydrogen
(via sciencedaily.com) Researchers have developed a practical way to produce green hydrogen using sustainable catalysts and say their work is a major step towards production simpler, more affordable and more scalable.
Published The Greenland Ice Sheet is close to a melting point of no return
(via sciencedaily.com) A new study using simulations identified two tipping points for the Greenland Ice Sheet: releasing 1000 gigatons of carbon into the atmosphere will cause the southern portion of the ice sheet to melt; about 2500 gigatons of carbon means permanent loss of nearly the entire ice sheet. Having emitted about 500 gigatons of carbon, we're about halfway to the first tipping point.
Published Improved wastewater treatment could lead to significant reduction in greenhouse gas emissions
(via sciencedaily.com) New research has shown that methane emissions from urban areas are underestimated by a factor of three to four and that untreated wastewater may be a contributing factor.
