Design of Lipid-Based Nanocarriers via Cation Modulation of Ethanol-Interdigitated Lipid Membranes

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 […]

Dual modality neutron and x-ray tomography for enhanced image analysis of the bone-implant interface

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 […]

Neutron diffraction for residual stress management in metal 3D printing by LPBF

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 […]

Emergent magnetic behavior in the frustrated Yb3Ga5O12 garnet

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 […]

GISANS revealed water influence on biobased thin films

Nanostructured porous thin films made from biocompatible cellulose nanofibrils (CNF) are widely used due to their attractive properties such as made from renewable resources, low density, lightweight, thermal stability, and excellent mechanical properties. These prerequisites make CNF a promising precursor for the design of bio composites and bio-inspired sensors. One crucial question is the relation […]


The Polaris instrument at ISIS began operation as a high intensity, medium resolution powder diffractometer in the late 1980s. It quickly established a large and scientifically diverse research community, encompassing engineering, materials science, condensed matter physics, solid state chemistry and earth science. However, by the late 2000s many of the key components of the Polaris […]

Swelling of Thin Graphene Oxide Films Studied by in Situ Neutron Reflectivity

Multilayered Graphene Oxide (GO) materials such as membranes and thin films are known for their potential for selective ion permeation, nano-filtration, water desalination and gas barrier properties. Many recent studies have aimed at demonstration of selective permeation of certain ions and molecules through GO membranes. Membrane tests were demonstrated to be successful for relatively thin […]

Using neutron reflectivity to elucidate electro-responsiveness of interfacial layers of ionic liquids and their solutions

Ionic liquids (ILs) have been identified as promising replacements for conventional lubricants. Their ionic nature and wide electrochemical windows present a new horizon for electrical energy storage solutions and tribotronic lubrication, whereby the friction coefficient is controllable though use of an electric field. However, due to the high production costs the commercialisation of IL lubricants […]

Neutron scattering aids in understanding atherosclerotic plaque build-up – a game of hide and seek

Experimental set-up

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.
