Green hydrogen: "Rust" as a photoanode and its limits
Hydrogen will be needed in large quantities as an energy carrier and raw material in the energy system of the future. To achieve this, however, hydrogen must be produced in a climate-neutral way, for example through so-called photoelectrolysis, by us.....»»
Doom + Doom II is a great excuse to jump back into Hell, for free or for $10
Just how you remember it, but through a 4K, 120 fps accessible lens. Enlarge / I don't know what this flame crossbow (?) is from the Legacy of Rust campaign, but I am going to keep running and gunning until I get it. (credit: Bet.....»»
3D laser printing with bioinks from microalgae
Microalgae such as the diatom Odontella aurita and the green alga Tetraselmis striata are especially suitable as "biofactories" for the production of sustainable materials for 3D laser printing due to their high content in lipids and photoactive pigm.....»»

Green belts need modernizing—a more "multifunctional" approach can benefit people and planet
Green belts are more than just spaces; for many people, they're places providing a brief escape from the city. Land designated as green belt—and protected from building—can also store carbon and hold water at times of flooding and drought......»»

Kids" sport always cancelled due to rain-soaked grounds? Green infrastructure can help
It's been a rainy winter in many parts of Australia, wreaking havoc on kids' sporting competitions. As mums, it has been frustrating to see so many of our kids' sports matches (and training sessions) canceled because of waterlogged grounds......»»
Chemical and transportation industries could boost with new catalyst coating
Coupling electrochemical conversion of the greenhouse gas CO2 with renewable electricity sources—such as solar and wind—promises green production of high-demand chemicals and transportation fuels. Carbon dioxide coupling products such as ethylene.....»»
Retreating Andean rocks signal the world"s glaciers are melting far faster than predicted, report scientists
Rocks recently exposed to the sky after being covered with prehistoric ice show that tropical glaciers have shrunk to their smallest size in more than 11,700 years, revealing the tropics have already warmed past limits last seen earlier in the Holoce.....»»
New study reviews progress in ternary hydrogen-rich superconductors
Room-temperature superconductivity has been a century-long-held dream of scientists. Hydrogen-rich compounds at high pressures are predicted to be potential high-temperature and even room-temperature superconductors and have become one of the superco.....»»
Green hydrogen: "Artificial leaf" becomes better under pressure
Hydrogen can be produced via the electrolytic splitting of water. One option here is the use of photoelectrodes that convert sunlight into voltage for electrolysis in so-called photoelectrochemical cells (PEC cells). A research team at HZB has now sh.....»»
Green synthesis of copper oxide nanoparticles from mangifera indica: A solution for agricultural disease management
A research team has successfully synthesized green copper oxide nanoparticles (CuO.NPs) from Mangifera indica (M. indica) leaf extract. The CuO.NPs showed potent activity against gram-positive and negative bacteria, as well as fungicidal effects on p.....»»
Scientists now know when an ancient lake supported human life in the Namib Sand Sea
Desert regions in northern Africa and the Arabian Peninsula have been well studied by archaeologists as the home of early humans and as routes of migration along "green corridors.".....»»
More Aussies are concerned the transition to renewables will hurt them financially
Support for Australia transitioning to renewable energy is strong across the country (with 59% support), but 41% are concerned about the negative impacts of the transition to green energy on cost-of-living and household energy bills (up 10% since 202.....»»
