Researchers develop reusable "sponge" for soaking up marine oil spills—even in chilly northern waters
Oil spills, if not cleaned up quickly and effectively, can cause lasting damage to marine and coastal environments. That's why a team of North American researchers are developing a new sponge-like material that is not only effective at grabbing and h.....»»
Scientists explore how single-atom catalysts impact water purification in advanced oxidation process
The rapid increase in global industrialization in the past centuries has resulted in the disposal of excessive toxic pollutants into the environment, seriously threatening the aquatic ecosystem and human health. Peroxymonosulfate-based advanced oxida.....»»
Speeding up calculations that reveal how electrons interact in materials
Materials scientists and engineers would like to know precisely how electrons interact and move in new materials and how the devices made with them will behave. Will the electrical current flow easily within the material? Is there a temperature at wh.....»»
Producing gold nano-particles (and hydrogen) in water without the need for toxic chemicals
In a surprise discovery, Flinders University nanotechnology researchers have produced a range of different types of gold nanoparticles by adjusting water flow in the novel vortex fluidic device—without the need for toxic chemicals. The article, "Na.....»»
Researchers develop high-performance blue organic LEDs based on thermally activated delayed fluorescence material
Organic light-emitting diodes (OLEDs) have become a leading display technology. The luminescent material is a core component of OLEDs. Thermally activated delayed fluorescence (TADF) materials have emerged as promising emitters for achieving high-eff.....»»
Salty soil sensitizes plants to an unconventional mode of bacterial toxicity
A collaborative study between researchers from the Max Planck Institute for Plant Breeding Research and the Fraunhofer Institute for Molecular Biology and Applied Ecology has shown how a single metabolite can render bacteria toxic to plants under hig.....»»
Tropical forest resilience to seasonal drought linked to nutrient availability
Tropical forests are highly productive ecosystems, accounting for nearly half of the global forest carbon sink. If tropical forests can no longer remove carbon dioxide from the atmosphere, the effects of climate change may become even more severe......»»
