2D sandwich sees molecules with clarity

Researchers adapt 2D 'sandwich' for surface-enhanced Raman spectroscopy

18-May-2020

A sandwich of molybdenum, sulfur and selenium turns out to be deliciously useful for detecting biomolecules. Tests at Rice University's Brown School of Engineering of a two-dimensional Janus compound showed it could be an effective and universal platform for improving the detection of ...

Disordered materials could be hardest, most heat-tolerant carbides

Simulations predict new class of carbides

28-Nov-2018

Materials scientists at Duke University and UC San Diego have discovered a new class of carbides expected to be among the hardest materials with the highest melting points in existence. Made from inexpensive metals, the new materials may soon find use in a wide range of industries from machinery ...

Watching two-dimensional materials grow

30-Aug-2018

Atomically thin crystals will play an ever greater role in future – but how can their crystallisation process be controlled? A new method is now opening up new possibilities. They are among the thinnest structures on earth: “two dimensional materials” are crystals which consist of only one or a ...

A Successful Coupling

Bioinspired enzyme model with a redox switch

29-Aug-2018

Coupled oxygen transfer and electron transfer reactions that use cofactors are enzymatic reactions of crucial significance to all lifeforms from bacteria to vertebrates. In the European Journal of Inorganic Chemistry, scientists have introduced a model for the enzyme sulfite oxidase. It is based ...

Why nanomaterial loses superconductivity

11-Jul-2018

The struggle to keep drinks cold during the summer is a lesson in classical phase transitions. To study phase transitions, apply heat to a substance and watch how its properties change. Add heat to water and at the so-called "critical point," watch as it transforms into a gas (steam). Remove heat ...

Charging ahead to develop better batteries

29-Mar-2018

Cellphones go dark during important conversations because a battery hasn't been recharged. Or the automotive industry revs up with excitement for a new battery-powered vehicle, but it needs frequent recharging. Or yardwork is delayed because the battery for your string trimmer is ...

Molecular magnetism packs power with 'messenger electron'

15-Nov-2017

Electrons can be a persuasive bunch, or at least, a talkative bunch, according to new work from John Berry's lab at the University of Wisconsin-Madison. The spins of unpaired electrons are the root of permanent magnetism, and after 10 years of design and re-design, Berry's lab has made a molecule ...
