Over the past few years, responsive materials - materials that change their structure when chemical, thermal, or mechanical stimuli
are applied - have been studied extensively. A team of researchers used high-pressure X-ray diffraction on the Extreme Conditions
beamline (I15) to study stimuli-responsive metal-organic frameworks (MOFs), a class of synthetic, crystalline, and porous materials
constructed from organic and inorganic building units. Some MOFs are known to be flexible, and to ...

Climate change, dwindling supplies of fossil fuels, and growing environmental awareness are all contributing to a surge of interest in electric vehicles. However, battery-powered electric vehicles cost more, and have a shorter range, than petrol/diesel vehicles, due to the energy density of lithium-ion batteries, for which cathode materials are currently a limiting factor.

A type of 3D printing called laser additive manufacturing (LAM) uses a high-energy laser beam to melt powder particles into a solid
structure in under 1/1000th of a second. The powder melting process controls how materials are formed, governing the overall product
performance. However, the fast laser-material interaction makes it difficult to optimise the processing conditions, resulting in
defects. The presence of defects slows down the adoption of LAM for safety-critical engineering ...

Alzheimer’s disease is the most common form of dementia, yet its cause is unclear and there is no effective treatment. A hallmark of
Alzheimer’s disease is the formation of amyloid plaques in the brain that disrupt its normal function. There is also an imbalance of
metals, with increased levels of iron and harmful reactive iron forms being associated with amyloid plaques.

The chemical industry produces a tremendous amount of waste. Often this arises from the need to separate the product from a solution
containing by-products and a dissolved catalyst. 85% of all industrial chemical processes use catalysts, chemicals that speed up a
reaction but do not get used up in the process, and they are often expensive metals such as palladium.

Aragonite is a common crystalline form (polymorph) of calcium carbonate, an important biomineral found, for example, in
seashells. Outside of the natural environment, aragonite usually only crystallises from solution at high temperatures, or in the
presence of magnesium ions. However, although organisms can readily form aragonite, the way in which they do so remains
unclear.

An international team of researchers has demonstrated a novel method for studying the microscopic structure of chemical bonds,
the valence electron density of crystals, and light-matter interactions at the atomic scale resolution, with synchrotron radiation.

Magnetic skyrmions are promising candidates for the next generation of memory devices as they allow increased storage density,
and require less energy.

Computers based on silicon are energy-hungry, and the search for energy-efficient alternatives is increasingly important. Electronic
components based on insulating magnetic oxides should be much more efficient at storing and manipulating information. In order
to operate at room temperature, such devices would rely on the presence of ‘magnetic knots’ (vortices), which would protect stored
information from thermal fluctuations.omputers based on silicon are energy-hungry, and the search for ...

omplementary techniques that can maximise information derived from precious soft tissue samples are extremely valuable. A team
from the Wolfson Centre for Age Related Diseases wanted to use 3D imaging to track how disease spreads through spinal tissue,
followed by traditional 2D histology to probe the regions of interest identified in these scans at the molecular level. However, most 3D
imaging methodologies require tissue preparation that prevents its subsequent use, or are too slow ...

A new class of electronic devices, often referred to by the term Mottronics, is based on charge correlations between the electrons.
Transition metal oxides exhibit fascinating phenomena such as the Mott metal-to-insulator transitions, electronic phase transitions
that are of potential interest for future device applications. However, further progress in material development is required to make
high quality thin films of prototypical Mott materials available, and to establish methods to ...

Electrically conductive Metal-Organic Frameworks (MOFs) are promising materials for electronic devices, owing to their unique capability
to adsorb guest molecules. Processing them as ultrathin films is one of the key requirements for the development of electronic devices,
and might offer new perspectives in fields of key environmental value such as photovoltaics, photocatalysis or sensing.

If you imagine a solid bead rolling on a soft cushion, it leaves distortions in the cushion in its wake. Transfer this analogy to the quantummechanical
realm, and the condensed matter physics version of the rolling bead is a polaron.
Holstein polarons are small composite particles composed of an electron dragging a cloud of lattice distortions. Although they were predicted to play a key role in high-temperature superconductivity and solar cells, the spectroscopic signature of Holstein ...

RNA polymerase (Pol) III is a major determinant of lifespan in eukaryotes (organisms whose cells have a nucleus enclosed within membranes, unlike bacteria). The level of Pol III transcription is tightly linked to the rate of growth, as it is known to play a role in cancer, and neurodegenerative diseases. A better understanding of the structure of Pol III could lead to new therapies for these
diseases. However, Pol III is the most complex nuclear RNA polymerase.
