We propose to investigate the spin dynamics in the frustrated antiferromagnet beta-CaCr2O4. Its structure consist in one dimensional chains of Cr+3 forming the legs of zig-zag...

Methylammonium lead iodide has recently been recognised as an excellent photovoltaic material, with energy conversion efficient of up to 15% with the prospect of gaining higher...

Faster-than-expected ageing is observed in some seeds (e.g. orchids, coffee, citrus, willows) stored dry at -20°C, the standard temperatures of seed banks. This ageing has been...

Organic-inorganic perovskites have recently been shown to be potentially efficient and inexpensive photovoltaics. These materials undergo a series of structural transitions and...

With the discovery of almost 3000 exo-planets it is clear that planet formation is a by-product of star formation, yet in the micron ? cm size range, where relative velocities...

We propose an investigation of the spin-waves in the recently discovered room-temperature skyrmion material Co8Zn8Mn4. The ground state of Co8Zn8Mn4 is a very long wavelength...

The composition Ni2.04Mn1.4Sn0.56 belongs to the group of metamagnetic shape memory alloys and it shows multiple magnetic phases as a function of temperature. In a recent muon...

Producing meat analogue instead of real meat is one effective way to reduce carbon emissions and improve animal welfare. Calcium caseinate (CaCas) is a prominent candidate for...

ZSM-5 zeolites are used as additives in Fluidised Catalytic Cracking (FCC) units to increase the yield of LPG alkenes by conversion of gasoline-range hydrocarbons, forming a key...

Zaccai et al. proposed to build up a neutron Dynamics Data Bank which would be populated with dynamical data of biological macromolecules measured with different techniques,...

Water ice forms a remarkable diversity of structures, occurring in as many as 17 crystalline forms. Water ice also shows other interesting and unusual properties. For example,...

Due to the importance of developing efficient biomass conversion processes, the mobility of lignin constituents phenol and catechol in zeolite Beta will be studied using QENS....

We have investigated the magnetic structure and crystal field excitations (CEF) of CeT2Al10 (T=Os and Ru). The observed magnetic moment along the c-axis does not agree with that...

The Mn(II) phases LaSrMnO3.5 and LaBaMnO3.5 have been prepared by the topotactic reduction of LaSrMnO4 and LaBaMnO4 respectively. Preliminary neutron diffraction data show that...

Frustration occurs in materials where antiferromagnetic (spin up and spin down pairs) are incomparible with the underlying crystal morphology, for example where the connectivity...

Conductive polymers (CP) show desirable physicochemical properties, with CP-based nanocomposites being manufactured for various applications i.e. sensors The filler particles...

Following a recently succesfull measurement of the structure of a monolayer of n-butane adsorbed on MgO we wish to perform neutron diffraction measurements of monolayers of...

In this proposal we will pioneer the use of QENS in combination with molecular biology mutagenesis and in silico design to guide the re-engineering of a glycoside hydrolase,...

Discrete energy level form in quantum mechanical systems and if carefully measured the population density of the levels can be probed and manipulated. The consequence of this...

Development of new cryopreservation strategies has major potential in medicine and agriculture, and is critical to the conservation of endangered species that currently cannot...
