Controlling residual stresses in friction stir welds
Aluminium is very difficult to weld; that is why aircraft are traditionally riveted. Friction Stir Welding (FSW) is a new method by which panels can be joined together by passing a rotating tool down the weld-line.
Water diffusion in drug delivery microgels
Polymeric microgels consist of nanometer-sized spheres. The spaces inside the spheres can be filled with a pharmacologically-active material – a drug – suspended in water. Such microgels are biocompatible, and so they have promising applications as injec
Dihydrogen complex or classical dihydride?
The structure of compounds containing more than one H atom bonded to a transition metal may layon a continuum between two extremes: separatebonds between the metal (M) and each H atom with no direct H-H bonds (classical polyhydride), and a dihydrogen co
Nano-structures in surfactant mixtures revealed
In many commonplace surfactant-based formulations (comprising ionic/nonionic surfactant mixtures) the addition of cosurfactants such as straight-chain alkanols and more complex alcohol structures (such as perfumes) can have an impact upon the solution.
Sorting out the structure of multiferroic BiFeO3
Multiferroics are technologically-important materials which simultaneously exhibit electric order (alignment of electric dipoles in an electric field) and magnetic order (alignment of magnetic spins in a magnetic field).
How do molecular crystals form?
How does the ordering in a crystal arise from the interactions present? Solving the structure shows what the structure is, but not how it arises.
Dopant atoms strain perovskites
A variety of interesting and potential useful materials are produced when a perovskite crystal structure is distorted by the presence of dopant atoms.
Iron pnictide superconductors: the impact of ISIS
The recent discovery of superconductivity in several iron- and arsenic-based compounds with critical temperatures as high as 55K has caused great excitement because they are the first non-copper-based high-temperature superconductors.
A clear view through muddy water
In recent years water quality scientists have become increasingly aware of the significance of nanoparticles (defined as <100 nm in size) in the transport of pollutants and their potential impacts on the ecology and health of streams and rivers.
Superconductors take a spin
Experiments at ISIS suggest that magnetic interactions may be the cause of high-temperaturesuperconductivity.
Probing the past
The study of ancient artefacts is complicated by the desire not to change or damage the objects in any way.
The secrets of storing hydrogen
Concern over climate change and a dwindling supply of fossil fuels mean that there is increasing interest in alternative forms of energy.
Welding the unweldable
Neutron diffraction is helping aerospace engineers perfect ways of welding advanced alloys that are difficult to join.
Magnetism in thin films revealed
Data storage has improved in leaps and bounds over the last 30 years – consider the size of music storage devices, which hold hundreds of CDs and can fit in the palm of your hand.
Peering into polymers
Virtually every day we benefit from products made from thin film polymers. These special layers are used for everything from time release medications to anti-reflective coatings.
Neutron studies uncover the liquid structure of an important industrial solvent.
Stopping pollution in its tracks
When we bury our waste in landfill sites, the site often has a clay liner to prevent toxic chemicals from escaping and contaminating groundwater.
Ice cold in Titan
Neutrons explore the materials thought to makeup the mantles of the icy moons of the Solar System.
The many forms of ice
You might think that the ice on Earth would be the same as that on Iapetus, Saturn’s icy moon, but new research suggests they maybe quite different.
Minerals prefer to form a perfectly ordered crystal structure when they are cooled, but for some this is a hard task.
Hotter means smaller!
Most materials expand when they are heated, but a few do exactly the opposite and contract. Recent work at ISIS has helped to explain this puzzling phenomenon by studying the way that the atoms move.
