Ammonia attracts the shipping industry, but researchers warn of its risks      (via sciencedaily.com)     Original source 

Switching to ammonia as a marine fuel, with the goal of decarbonization, can instead create entirely new problems. This is shown in a study where researchers carried out life cycle analyses for batteries and for three electrofuels including ammonia. Eutrophication and acidification are some of the environmental problems that can be traced to the use of ammonia -- as well as emissions of laughing gas, which is a very potent greenhouse gas.

Intensifying the production of high-value compounds from industrial waste      (via sciencedaily.com)     Original source 

New research demonstrates how glycerol carbonate, a biosourced industrial additive, can be produced in record time using CO2 and a by-product of the cooking oil recycling industry. The process relies on a hybrid approach combining fundamental physical organic chemistry and applied flow process technology. Two industrial wastes are thus converted into glycerol carbonate, a biosourced rising star with high added-value.

Engineers unmask nanoplastics in oceans for the first time, revealing their true shapes and chemistry      (via sciencedaily.com)     Original source 

Millions of tons of plastic waste enter the oceans each year. The sun's ultraviolet light and ocean turbulence break down these plastics into invisible nanoparticles that threaten marine ecosystems. In a new study, engineers have presented clear images of nanoplastics in ocean water off the coasts of China, South Korea and the United States, and in the Gulf of Mexico. These tiny plastic particles, which originated from such consumer products as water bottles, food packaging and clothing, were found to have surprising diversity in shape and chemical composition.

Bright galaxies put dark matter to the test      (via sciencedaily.com)     Original source 

The earliest galaxies are thought to have formed as the gravitational pull of dark matter, which has been impossible to study directly, slowly drew in enough hydrogen and helium to ignite stars. But astrophysicists now show that after the Big Bang, hydrogen and helium gas bounced at supersonic speeds off dense, slowly moving clumps of cold dark matter. When the gas fell back in millennia later, stars formed all at once, creating small, exceptionally bright galaxies. If models of cold dark matter are correct, the James Webb Space Telescope should be able to find patches of bright galaxies in the early universe, potentially offering the first effective test for theories about dark matter. If it doesn't, scientists have to go back to the drawing board with dark matter.

Decarbonizing the world's industries      (via sciencedaily.com)     Original source 

Harmful emissions from the industrial sector could be reduced by up to 85% across the world, according to new research. The sector, which includes iron and steel, chemicals, cement, and food and drink, emits around a quarter of global greenhouse gas (GHG) emissions -- planet-warming gases that result in climate change and extreme weather.

Small yet mighty: Showcasing precision nanocluster formation with molecular traps      (via sciencedaily.com)     Original source 

Nanoclusters (NCs) of transition metals like cobalt or nickel have widespread applications in drug delivery and water purification, with smaller NCs exhibiting improved functionalities. Downsizing NCs is, however, usually challenging. Now, scientists have demonstrated functional NC formation with atomic-scale precision. They successfully grew cobalt NCs on flat copper surfaces using molecular arrays as traps. This breakthrough paves the way for advancements like single-atom catalysis and spintronics miniaturization.

Some plastic straws degrade quicker than others      (via sciencedaily.com)     Original source 

Not all plastics are created the same, and some last longer in the ocean than others. Scientists have been working for years to quantify the environmental lifetimes of a wide range of plastic goods to see which have the shortest and longest lifespans in the ocean. To determine what plastics persist in the ocean, the team tests different products in large tanks that recreate the natural ocean environment.
