Why green ammonia may not be that green
Ammonia has been in the news because of its suitability as a hydrogen carrier and fuel, in addition to being a vital ingredient in fertiliser. Existing distribution networks and the ease of turning ammonia gas into a liquid make ammonia a cost-effect.....»»
Eco-conscious fashionistas hampered by geographical barriers to return clothing
Eco-conscious consumers are not well-served by clothing companies claiming green credentials, as shoppers' location has a major impact on the effectiveness of clothing return schemes, a new study reveals......»»
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.....»»
Powering enzymes with light to make ammonia
The Earth's atmosphere contains large amounts of nitrogen in the form of dinitrogen gas (N2). Converting N2 to ammonia (NH3) is critical for making the fertilizer needed for agriculture......»»
Why wildfires are getting more dangerous
After more than a year of record-breaking heat, the peak of fire season is approaching across vast swathes of our green planet......»»
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......»»
Engineers develop general, high-speed technology to model, understand catalytic reactions
Researchers have been studying the industrial production of ammonia for a century. But they've struggled to find ways to improve the low-yield, low-efficiency process......»»
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.....»»
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.....»»
Ammonia-free gallium nitride semiconductor production found to improve crystal quality, reduce environmental impact
Gallium nitride (GaN) semiconductors can now be grown without ammonia, a toxic chemical that needs a sophisticated detoxifying system before it can be released into the atmosphere. The new technique is not only more environmentally friendly but also.....»»
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.....»»
