Superelasticity of a photoactuating chiral crystal

Superelasticity is an elastic response to an applied external force that occurs via phase transformation. The resulting actuation of the materials is an elastic response to external stimuli, including light and heat. While ...

Solving a crystal's structure when you've only got powder

Crystals reveal the hidden geometry of molecules to the naked eye. Scientists use crystals to figure out the atomic structure of new materials, but many can't be grown large enough. Now, a team of researchers report a new ...

Advanced algorithms plus exceptional X-ray laser reveal structures of not-so-neat-and-tidy materials

Francis Crick, who famously co-discovered the shape of DNA, once said: "If you want to understand function, study structure." Many decades later, this remains a tenet of biology, chemistry, and materials science.

Room-temperature crystallography aids new study of photosynthetic bacteria

Chemists have come to a deeper understanding of how photosynthetic bacteria convert light into chemical energy and discovered why one step in the process may be more robust than previously realized, according to a new study ...

Thermoelectric crystal conductivity reaches a new high

Just as a voltage difference can generate electric current, a temperature difference can generate a current flow in thermoelectric materials governed by its "Peltier conductivity" (P). Now, researchers from Japan demonstrate ...

Scientists discover the first ferromagnetic quasicrystals

Since the discovery of quasicrystals (QCs), solids that mimic crystals in their long-range order but lack periodicity, scientists have sought physical properties related to their peculiar structure. Now, an international ...

Scientists monitor the formation of a chemical bond for the first time

A new study has for the first time been able to monitor the different stages of a chemical reaction, as one bond breaks and another forms. The work, involving Nottingham Trent University, the University of Southampton and ...

Surface science methodology reveals relaxation and failure mechanisms of energy storage devices

Long cycle life and high safety are required for energy storage devices (ESDs) in their large-scale applications. Therefore, it's important to explore both the operating and failure mechanisms of ESDs.
