by Elisabetta Nocerino Symmetry-breaking phenomena underpin various intriguing physical properties in condensed matter such as magnetism [1,2,3,4] and superconductivity [5,6]. Understanding such fundamental properties holds significant importance for the development of cutting-edge technologies, including spintronics, quantum computing, and advanced magnetic materials, as well as foster innovation in energy-related applications . The crystalline solid NaCr2O4 represents […]
The physical properties of structural as well as functional components are largely governed by the materials microstructure. In polycrystalline materials, the crystallographic phase and preferred grain orientation (texture) can dominate the physical properties. A range of microscopy and diffraction techniques are hence routinely used for their characterization, but are prone to miss local variations across […]
The complexity of cellular membranes is not only reflected by their wide molecular composition but also in the wide range of morphologies with coexisting high and low curvature regions. Very little is known about the nanostructure of curved membranes, due to limitations in experimental and simulation approaches. Even though curvature-induced microscopic phase separation has been […]
It is our great pleasure to invite you to an online launch event and workshop to showcase two new software workflows which will be of interest to the Small-angle Scattering and Disordered Materials communities. The development of these tools has been funded by the Ada Lovelace Centre and they are intended to offer users new […]
The design of neutron systems, for example nuclear reactors and neutron sources, requires the usage of Monte-Carlo simulation software to predict the distributions of neutrons throughout the system. At low energies, the interactions of neutrons with a material is driven by interactions on the atomic and molecular scale and thus a proper description of this […]
The Swedish neutron community have long been asking for a way of contributing in-kind to ESS, and now it is possible.

In-kind collaborations can give a close connection to the ESS instrument projects and opportunities to be involved in first science at ESS.
An object’s bulk modulus quantifies its resistance to an isotropic compression. For soft deformable colloids the bulk modulus must be known to predict their response to crowding. Figure 1: (a) Sketch of the basic principle of our new method. Blue spheres represent the nanogels while the green lines are for the dPEG which, in neutrons, […]
Lipid nanoparticles (LNPs) are currently under intense scrutiny for vaccine delivery and RNA therapies. Key to their successful optimisation and translation is a nanoscale, single particle characterisation of the relationship between LNP structure, composition, and performance. Maximising performance and understanding intracellular trafficking are key components of LNP rational design. Phospholipases, specific lipid modifying enzymes, are […]
DHODH (dihydroorotate dehydrogenase) catalyzes a key step in the biosynthesis of pyrimidines, precursors of nucleic acids needed for DNA and RNA synthesis in all living organisms. Because of this, DHODH is a drug target for the inhibition of inflammation and investigated as a target to inhibit cell proliferation (cancer) and viral replication. Human DHODH is […]
Spin liquids are a topical and fascinating subject of condensed matter physics, fueled by the hope to create novel ground-states of matter. Typically, the combination of antiferromagnetic interactions with strong frustration leads to a rich variety of highly correlated spin states rather than to conventional order. Experimental research, however, has remained inconclusive in respect to […]
Nakhlite meteorites are igneous rocks from Mars that reacted with water ~630 million years ago while still part of the Martian bedrock, during a time that is often suggested to have been a “dry” period on Mars. However, magmatism and meteorite impacts can trigger so called hydrothermal systems with warm fluids circulating in the bedrock, […]
Li-S batteries are promoted as a highly promising energy storage solution, but the specific energy demonstrated so far (~400 W h kg‑1) is restricted by the low utilization of active materials in both lithium and sulfur electrodes. The incomplete discharge process of the sulfur electrode is associated with precipitation of insulating reaction products from polysulfide intermediates. This process, […]
Membrane proteins mediate communication between the outside and inside of cells, and are common drug targets.

The phase behavior of phospholipids dictates various membrane properties, such as permeability, shape, and stiffness. Some phospholipids exhibit a polymorphic gel phase and are capable of undergoing membrane interdigitation under specific conditions, such as in the presence of short-chain alcohols (e.g., ethanol). Ethanol-induced interdigitation of diacyl–phosphatidylcholine bilayers has been leveraged to formulate large unilamellar vesicles […]
The quality of the bone tissue formed at the contact interface with a metallic implant is of utmost importance for the structural integrity of implant fixation. This quality can be assessed, e.g., based on its 3D microstructure, which is commonly visualised using x-ray tomography. However, due to large differences in interaction strength between the metal […]
In metal 3D powder bed printing, a part is built on a baseplate layer-by-layer through powder deposition and selectively melting of the deposited powder layer. The localized rapid heating and cooling cycles involved inevitably result in the development of residual stresses in the already solidified bulk of the part. The residual stresses can cause in-process […]
Emergence is the phenomenon of collective behaviour that cannot predicted from considerations of the individual constituents but rather through complex interactions resulting in novel and diverse states of matter. A well-known example is the benzene ring, a loop of six carbon atoms, that can be further interconnected to create carbon nanotubes. Emergent behaviour in magnetic […]

A key requirement for the electrolyte is a high proton conductivity […]
Many low molecular weight drugs, like classical surfactants, contain both hydrophobic and hydrophilic groups. However, due to their lower molecular weight and less distinct separation into hydrophobic and hydrophilic regions, the self-assembly of such drugs in aqueous solutions is less easy to describe in general terms. To gain more understanding of the interaction between such […]
In recent year, new therapeutic modalities involving delivery of biological molecules such as RNA, peptides and oligonucleotides have shown promising results to treat diseases that are currently hard to tackle with standard small molecules approaches.

Why is it so that individuals with good cholesterol values develop cardiovascular disease, whilst other individuals with poor values remain healthy? Cholesterol and other fats are transported through the blood via specific transporters called lipoproteins. The most well-known are the so called “good” and “bad” cholesterol. Understanding these particles in structure and composition and the way they interact with artery wall is crucial in understanding this disease, the main killer of the West. Such knowledge would aid in improving diagnostic tools as well as in development of new drugs.
