Gallium has a low melting point and forms a liquid just above room temperature. The melting curve has a negative slope and when pressure is applied room pressure phases will...

In condensed matter physics, the search for new exotic quantum ground states has become a central theme over the past few years. Among the 3D quantum spin liquid candidates, the...

C60 represents the prototypical case study for a highly geometric nanoscopic entity that exhibits exotic dynamical and thermodynamic transitions. Yet little in general is known...

We have recently discovered that above 2 GPa in the liquid/fluid forms water and methanebecome miscible in proportions up to 33 mole% of methane. This proposal is for time to...

Modulation occurs when there is ordering on two (or more) length scales. When the ratio of these is an integer, the modulation is said to be commensurate, i.e. one ordering is...

Iron-based superconductors (FeSCs) have been an essential research area in condensed matter physics. Spins of iron sites forming a long periodic configuration, called the...

It has always been assumed that CaSnO3 perovskite remains orthorhombic (Pbnm) as a function of temperature up to its melting point, and is rather unremarkable in many ways....

The aim of the proposed experiment is to determine the temperature dependence of the ordered magnetic structures of LaMnSbO and NdMnSbO. These oxy-antimonides are related to the...

The discovery of superconductivity in iron-pnictide materials has generated much excitement in the past year about possibly unifying mechanisms for high-temperature...

This proposal concerns the metal-organic framework (MOF), cobalt imidazolate. Imidazole (im) is a small, flat organic molecule that forms slightly bent metal-im-metal linkages,...

We request beam time on Vesuvio to investigate the samples taken from and prepared in parallel with Superconducting Radio Frequency (SRF) Nb cavities in order to investigate the...

The hyperhoneycomb lattice can be viewed as a 3D version of the 2D honeycomb and the new magnetic compound [(C2H5)3NH]2Cu2(C2O4)3 provides a rare example. Honeycomb type...

In recent years, the investigation of metamagnetic properties of first order magnetic systems has become revolutionary. The rare-earth based compound Nd5Ge3 exhibits a magnetic...

Our recent high (P,T) developments at PEARL beamline will allow us to study the kinetic and thermodynamic behavior of boron 11B under pressures up to 12 GPa and temperatures up...

We propose to study the structure of liquid CO2 by neutron diffraction under high pressure and high temperatures to 6 GPa / 800 K. Carbon dioxide belongs to the most fundamental...

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...

We will study the formation of methane hydrates in situ in the presence of swelling clays. The aim is to understand and control heterogeneous hydrate nucleation at this...

Polyaromatic hydrocarbons (PAHs) are small disk shaped molecules that are important to a number of active research areas. These include natural systems, such as asphaltenes, the...

We have recently reported colossal magnetoresistance (CMR) in NdMnAsO0.95F0.05. The CMR in NdMnAsO1-xFx arises due to competition between a strongly correlated antiferromagnetic...

In our daily life, we are aware that liquid and its vapour can coexist. As we increase the temperature and pressure, however, there is a point called the critical point where...
