Dynamical Transitions in the Ogg Glasses
We request 4 days on IRIS to study the temperature dependance of the structural dynamics in amorphous sodium-ammonia (Na-NH3). This will be the first investigation of the... -
The Grüneisen and Anderson-Grüneisen parameters of mirabilite (Na2SO4.10D2O)
Sodium sulfate decahydrate (mirabilite) may be an important rock-forming mineral in the outer solar system, comprising a large fraction of the mantles of Jupiter's icy moons; it... -
Search for neutron spin-resonance in the exotic heavy fermion superconductor ...
Neutron spin resonance mode is a common feature in different classes of magnetic superconductors; nonetheless, the microscopic origin of the mode is still unclear. In general,... -
The dynamics of water in halloysite nanotubes
Water is important in many scientific and technological areas, yet our understanding of this remarkable liquid remains very incomplete. In may cases, it is the properties of... -
Magnetic structure of heavily Fermion TbxYb1-xAgGe
YbAgGe has an enhanced electronic specific heat coefficient and two magnetic phase transitions at TM1=0.8K and TM2=0.65K. We have grown a series of TbxYb1-xAgGe and YbAgGe... -
Correlation of structures, compositions and magnetism of copper-deficient lay...
This is part of a larger experiment which will investigate three related systems which contain copper deficient anti-fluorite-type copper sulfide layers. The overall aim is to... -
Molecular weight dependence of 2D-confined dynamics in glass-forming systems
We seek to explore the dynamics of glass forming systems upon extreme 2D-confinement. These experiments are motivated by preliminary experiments on oligomers and macromolecules... -
