Sticking power of plant polyphenols used in new coatings
A simple kitchen sink experiment helped Northwestern University researchers discover that green tea leaves not only can be used to steep a good cup of tea, but they make an excellent antibacterial coating, too.
Explosive nanotechnology: Highly reactive nanoenergetic formulations based on periodate salts
(Phys.org) —Whether they are rocket propellants or fireworks, all explosives contain a fuel and an oxidizing agent. Sometimes both are in the same molecule, like in TNT; sometimes the explosive is a mixture, ...
Metal model mimics metalloenzymes
(Phys.org) —Metal ions play critical roles throughout biochemistry, often facilitating the cleavage of the bond between the two atoms in an oxygen molecule in metalloenzymes. They are the key to oxidizing ...
German scientists solve nonclassical 2-norbornyl carbocation structure
The quantum secret to alcohol reactions in space
Chemists have discovered that an 'impossible' reaction at cold temperatures actually occurs with vigour, which could change our understanding of how alcohols are formed and destroyed in space.
A designer enzyme for alternative energy
(Phys.org) —Imagine pulling energy out of thin air. Yi Lu and his colleagues are on that path, in a quest to find alternatives to fossil fuels. The team has designed an enzyme that can harvest the energy ...
Exposure to air transforms gold alloys into catalytic nanostructures
(Phys.org) —Gold bars may signify great wealth, but the precious metal packs a much more practical punch when shrunk down to just billionths of a meter. Unfortunately, unlocking gold's potential often requires ...
DNA damage: The dark side of respiration
(Phys.org) —Adventitious changes in cellular DNA can endanger the whole organism, as they may lead to life-threatening illnesses like cancer. Researchers at LMU now report how byproducts of respiration cause mispairing ...
Team uncovers fundamental property of astatine, rarest atom on Earth
An international team of scientists, including a University of York researcher, has carried out ground-breaking experiments to investigate the atomic structure of astatine (Z=85), the rarest naturally occurring ...
Solar discovery sets new record for low-grade silicon
(Phys.org) —Solar engineers from UNSW have developed an innovative method to dramatically improve the quality of low-grade silicon, promising to significantly improve electrical efficiency and reduce the cost of solar panels.
Study provides new evidence of cooling properties of atmospheric molecule
(Phys.org) —Scientists have discovered further evidence for the existence of new molecules in the atmosphere that have the potential to off-set global warming by reacting with airborne pollutants.
Research reveals what turns free radicals on
(Phys.org) —UOW chemistry researchers have revealed what turns free radicals on...and off again in an article recently published in Nature Chemistry.
Researchers develop tiny gradient chip: System makes it easier to measure chemical reactivity
Dutch nanotechnologists at the University of Twente's MESA+ research institute have developed a tiny chip that makes it easy to create micrometre scale gradients. Gradients are gradual transitions in specific ...
Power behind primordial soup discovered
(Phys.org) —Researchers at the University of Leeds may have solved a key puzzle about how objects from space could have kindled life on Earth.
