Semi-liquid metal anode for next-generation batteries

New anode could help create a safer high energy lithium metal battery

17-Jun-2019

Researchers from Carnegie Mellon University's Mellon College of Science and College of Engineering have developed a semiliquid lithium metal-based anode that represents a new paradigm in battery design. Lithium batteries made using this new electrode type could have a higher capacity and be much ...

Fiber-optic probe can see molecular bonds

Pointing the new nanoscopy tool like a Harry Potter wand reveals a high-resolution image of molecules

12-Jun-2019

In "Avengers: Endgame," Tony Stark warned Scott Lang that sending him into the quantum realm and bringing him back would be a "billion-to-one cosmic fluke." In reality, shrinking a light beam to a nanometer-sized point to spy on quantum-scale light-matter interactions and retrieving the ...

Creating new molecular sieves

Researchers make organic frameworks that could sift antibiotic residue out of water

11-Jun-2019

An international team of researchers recently synthesized polyarylether-based covalent organic frameworks, the most stable crystalline porous material on record. The team, which includes the University of Delaware's Yushan Yan and Jilin University's Qianrong (Frank) Fang, a former postdoctoral ...

Sensitive new laser technique detects volatile organic compounds

Accurate measurements of mixed airborne molecules could improve breath alcohol tests, climate research and sensors for occupational health and safety

05-Jun-2019

Researchers have developed a new way of operating miniature quantum cascade lasers (QCLs) to rapidly measure the absorption spectra of different organic molecules in the air simultaneously. The technique offers a sensitive method for detecting low concentrations of volatile organic compounds ...

Nanomaterial safety on a nano budget

Rice University researchers share their protocol for handling carbon nanotubes

05-Jun-2019

With a little practice, it doesn't take much more than 10 minutes, a couple of bags and a big bucket to keep nanomaterials in their place. The Rice University lab of chemist Andrew Barron works with bulk carbon nanotubes on a variety of projects. Years ago, members of the lab became concerned ...

Researchers can now predict properties of disordered polymers

04-Jun-2019

Thanks to a team of researchers from the University of Illinois at Urbana-Champaign and the University of Massachusetts Amherst, scientists are able to read patterns on long chains of molecules to understand and predict behavior of disordered strands of proteins and polymers. The results could, ...

Scientists offer designer 'big atoms' on demand

03-Jun-2019

In the not-so-distant future, researchers may be able to build atoms to your specifications with the click of a button. It's still the stuff of science fiction, but a team at the University of Colorado Boulder reports that it is getting closer when it comes to controlling and assembling particles ...

NIST Study Identifies Chemical Blends as Possible Alternative Refrigerants

31-May-2019

More than a dozen chemical blends could serve as alternative refrigerants that won’t heat the atmosphere as much as today’s refrigerants do, or catch fire, according to a new computational study by the National Institute of Standards and Technology (NIST). The NIST study identified the 22 “best” ...

Building a better salt trap: Scientists synthesize a molecular 'cage' to trap chloride

New molecule designed at Indiana University could help reduce growing level of salt contaminants flowing into freshwater streams and lakes across the US

31-May-2019

Indiana University researchers have created a powerful new molecule for the extraction of salt from liquid. The work has potential to help increase the amount of drinkable water on Earth. Built using chemical bonds previously regarded as too weak, the new molecule is about ten billion times ...

Energy researchers break the catalytic speed limit

31-May-2019

A team of researchers from the University of Minnesota and University of Massachusetts Amherst has discovered new technology that can speed up chemical reactions 10,000 times faster than the current reaction rate limit. These findings could increase the speed and lower the cost of thousands of ...
