New superacid converts harmful compounds into sustainable chemicals      (via sciencedaily.com) 

Researchers have succeeded in producing very special catalysts, known as 'Lewis superacids', which can be used to break strong chemical bonds and speed up reactions. The production of these substances has, until now, proven extremely difficult. The chemists' discovery enables non-biodegradable fluorinated hydrocarbons, similar to Teflon, and possibly even climate-damaging greenhouse gases, such as sulphur hexafluoride, to be converted back into sustainable chemicals.

Chaos on the nanometer scale      (via sciencedaily.com) 

Chaotic behavior is typically known from large systems: for example, from weather, from asteroids in space that are simultaneously attracted by several large celestial bodies, or from swinging pendulums that are coupled together. On the atomic scale, however, one does normally not encounter chaos -- other effects predominate. Now scientists have been able to detect clear indications of chaos on the nanometer scale -- in chemical reactions on tiny rhodium crystals.

Novel air filter captures wide variety of pollutants      (via sciencedaily.com)     Original source 

An air filter made out of corn protein instead of petroleum products can concurrently capture small particulates as well as toxic chemicals like formaldehyde that current air filters can't. The research could lead to better air purifiers, particularly in regions of the world that suffer from very poor air quality. The more environmentally friendly air filter was able to simultaneously capture 99.5% of small particulate matter, similar to commercial HEPA filters, and 87% of formaldehyde, which is higher than specially designed air filters for those types of toxics.

A molecular machine's secret weapon exposed      (via sciencedaily.com) 

RNAs can wreak havoc on cells if they aren't removed at the right time. Dis3L2 is a molecular 'machine' that untangles and chews up RNAs, but scientists have been unable to explain how. Biochemists have now pieced together the answer. By shape-shifting, the machine unsheathes a lethal wedge that pries open and chews up RNA molecules, a behavior previously unseen.

'Electronic nose' built with sustainably sourced microbial nanowires that could revolutionize health monitoring      (via sciencedaily.com) 

Scientists recently announced the invention of a nanowire 10,000 times thinner than a human hair that can be cheaply grown by common bacteria and tuned to 'smell' a vast array of chemical tracers -- including those given off by people afflicted with a wide range of medical conditions, such as asthma and kidney disease. Thousands of these specially tuned wires, each sniffing out a different chemical, can be layered onto tiny, wearable sensors, allowing healthcare providers an unprecedented tool for monitoring potential health complications. Since these wires are grown by bacteria, they are organic, biodegradable and far greener than any inorganic nanowire.

Artificial intelligence conjures proteins that speed up chemical reactions      (via sciencedaily.com) 

Scientists have used machine learning to create brand-new enzymes, which are proteins that accelerate chemical reactions. This is an important step in the field of protein design as new enzymes could have many uses across medicine and industrial manufacturing. The research team devised deep-learning, artificial intelligence algorithms that created light-emitting enzymes called luciferases. Laboratory testing confirmed that the new enzymes can recognize specific chemicals and emit light very efficiently.

Nanofluidic devices offer solutions for studying single molecule chemical reactions      (via sciencedaily.com) 

Researchers have developed principles and technologies of nanofluidic devices to freely manipulate nanomaterials, biomaterials, and molecules at the single-molecule level using fundamental technologies such as nanofluidic processing, functional integration, and fluidic control and measurement, which has pioneered the way to integrate various fields under nanofluidics. To elucidate the single molecule dynamics of chemical reactions in solution, using their unique nanofluidic devices, they outlined how they propose to solve problems such as precisely manipulating small molecules in solution and how to investigate extremely quick reactions, that only take nano- to picoseconds.
