The effect of aging on the break-up dynamics of Laponite suspensions was studied in an extensional geometry. It was found that samples of increased age undergo stronger necking at the midpoint. The thinning of samples, driven purely by motion of the... Read More about Studying the aging of Laponite suspensions using extensional rheology.

Physical Review Letters, 128(15), Article 157401. https://doi.org/10.1103/physrevlett.128.157401

The functionality of phonon-based quantum devices largely depends on the efficiency of the interaction of phonons with other excitations. For phonon frequencies above 20 GHz, generation and detection of the phonon quanta can be monitored through phot...

© 2019 American Physical Society. We present implementation of the alloy analogy model within fully relativistic density-functional theory with the coherent potential approximation for a treatment of nonzero temperatures. We calculate contributions o... Read More about Temperature-dependent resistivity and anomalous Hall effect in NiMnSb from first principles.

Evidence for Jahn-Teller effects in endohedral fullerenes (2018)

Endohedral fullerenes can be formed by encapsulating one or more atom or molecule inside the cavity of the fullerene molecule. When a light molecule is encapsulated, it will remain close to the centre of the fullerene molecule without any strong inte...

Fingermarks are a key form of physical evidence for identifying persons of interest and linking them to the scene of a crime. Visualising latent (hidden) fingermarks can be difficult and the correct choice of techniques is essential to develop and pr...
