Operando Analysis of Lithium/Sulfur Cells with SANS and deuterated solvents
Lithium sulfur (Li/S) batteries have a fivefold higher theoretical gravimetric energy density (2680 Wh/kgsulfur) than state-of-the-art lithium ion batteries. However, the strong... -
Conformation of thermo-responsive methacrylate based comb polymers in D2O sol...
A series of well defined comb polymers consisting of methacrylate backbones and oligo(2-ethyl-2-oxazoline) side chains was shown to exhibit lower critical solution temperature... -
Investigation of a frustrated quantum magnet with novel interaction scheme
SrCuTe2O6 consists of a 3-dimensional arrangement of spin-1/2 Cu ions that are coupled into network of isolated triangles,a highly frustrated hyperkagome lattice consisting of... -
Understanding the decomposition of ammonia by lithium-calcium imide
Among light metal amide-imide catalysts for ammonia decomposition, lithium-calcium imide is the most promising candidate for practical application. Ex situ diffraction data... -
Unpicking the signal of partial order from thermal motion in diffuse scatteri...
Orientationally-disordered water molecules in ice adopt a degree of partial order upon cooling, a process that is halted by kinetics at ~100 K in pure ice and ~60 K in KOH-doped... -
Spin dynamics in the 1/3rd magnetization plateau phase of a triangular quantu...
This experiment is part of our research programme to explore novel quantum phases and phase transitions induced by magnetic field in frustrated quantum magnets. The quasi-2D... -
In Situ High Pressure NMR study of the Direct Synthesis of NaAlH4
NaAlH4 has been a model system for metal hydride hydrogen storage materials since the reaction was identified to be reversible. The decomposition pathway has been described by a... -
