Hierarchically porous carbon networks embedded with single iron sites for efficient oxygen reduction
Currently, oxygen reduction reaction (ORR) suffers from sluggish kinetics and high overpotential, which usually requires costly platinum (Pt)-based materials. Transition metal single-atom catalysts (M–N–C), such as Fe–N4 and Co–N4 with high O.....»»
Morphology study paves the way for spider fang-inspired cutting tools
When we think of spiders, the first thing that comes to mind is their ability to weave intricate and robust webs. But their ability to cut their own silk—the toughest natural material—and strong or tough synthetic fibers such as carbon or Kevlar,.....»»

Low-temperature ammonia-to-hydrogen conversion achieved by applying an electric field
Hydrogen gas, owing to its high energy density and carbon-free nature, is gaining much attention as the energy source for a green and sustainable future. Despite being the most abundant element in the universe, hydrogen is mostly found in a bound sta.....»»
Graphene spike mat uses ordinary fridge magnet tech to fight antibiotic resistance
With strong bactericidal properties, graphene has the potential to become a game changer in the fight against antibiotic-resistant bacteria. So far there have been no efficient ways to control these properties—and thus no way to make use of graphen.....»»

Graphene at 20: Still no sign of the promised space elevator, but the material is quietly changing the world
Twenty years ago this October, two physicists at the University of Manchester, Andre Geim and Konstantin Novoselov, published a groundbreaking paper on the "electric field effect in atomically thin carbon films." Their work described the extraordinar.....»»
Chemists discover new ways in which single-celled organisms organize their DNA
It has only recently been discovered that single-celled organisms (bacteria and archaea) also have histones—proteins that structure DNA. Now, Leiden Ph.D. candidate Samuel Schwab has found that the histones in these organisms are much more diverse.....»»
Deeper corals may help shallow reefs recover in the Florida keys
Since the 1970s, coral reefs in the Florida Keys National Marine Sanctuary (FKNMS) have experienced catastrophic declines in coral cover, with as much as a 50% reduction between 1998 and 2011 alone. Although coral reefs within the FKNMS have been hea.....»»
Transforming agriculture from carbon source to sink: Study shows potential of carbon sequestration options
The food system is one of the most significant sources of greenhouse gas emissions on the planet, making the reduction of emissions in this sector a priority for policymakers around the world. IIASA researchers explored the potential of carbon seques.....»»
Water-free manufacturing approach could help advance 2D electronics integration
