In-situ high resolution neutron diffraction studies of cemented carbides
Cemented carbides are composite materials manufactured via powder metallurgy. The excellent wear resistance, high hardness, and high toughness make them widely used materials in... -
The high temperature high pressure behaviour of ammonia hydrates
Ammonia hydrates are important constituents of the outer solar system. In recent x-ray studies we have found evidence for a solid solution between ice and ammonia at high... -
Time Resolved Studies on Inorganic Film Formation at the Air-Solution Interface
In a recent SURF experiment on the formation of silica films templated with cat-anionic/polymer complexes we found that the film growth and evolution occurs on a faster time... -
High Temperature Micromechanics Ni-based Superalloys: Creep, Stress Relaxatio...
In this study, in-situ high-temperature loading investigations will be performed to characterise the micromechanics of a high strength alloy 720Li, during stress relaxation in... -
Proton diffusion in lithium imide: a quasi-elastic neutron scattering study
Li_2NH has been recently considered for H_2 storage applications. However, its low-T crystal structure is still controversial, with at least 6 options compatible with the... -
Temperature driven spin incoherence and criticality in the Luttinger liquid p...
We propose an experiment on the low energy spectrometer LET to study temperature effects on the Luttinger liquid (LL) phase on the spin ladder geometry. The spin ladder material... -
Kinetics of the ordering transition in ice Ih; crystal structure and thermal ...
Below 80 K ordinary water ice (ice Ih) undergoes a phase transition in which the randomly oriented molecules in the crystal adopt an ordered orientation. This ordered form of... -
