a continuous smooth amplitude spectrum curve corresponding the transition process and an impulse with the sinusoidal signal frequency, which corresponds to steady-state harmonic vibration of the particle; (iii) the frequency spectrum corresponding to the transition process of particle vibration is the intr...
If metal exsolution is considered to be driven by the material striving towards thermodynamic equilibrium and to be based on bulk defect-chemical reactions, the amount of exsolved metal would be expected to be temperature dependent. High temperatures should result in accelerated mass transport and ...
Within the Standard Model of Particle Physics the elementary building blocks of matter have been identified as leptons and quarks. Yet, it is still a challenge of contemporary subatomic physics to understand even the first level of compositeness, the structure of the nucleons as built from quarks...
In this paper, we propose a way to simplify the design of microstructured optical fibres with high sensitivity to applied pressure. The use of a capillary fibre with an embedded core allows the exploration of the pressure-induced material birefringence d
Liquid (usually a noble-element) filled, for non-accelerator experiments (neutrino or dark matter detection, i.e., rare events with very low cross-sections), where high-density and large active mass are required. Because of the long drift time, TPC is not a fast detector; therefore, it ...
The particokinetic data were decay corrected by the half-life of 125I (i.e., 60 days). The retention mass of the particles was presented as the percentage of the total injected dose per gram of tissue (%ID/g). Statistical analysis Independent t-test using the GraphPad Prism software (...

Atomically thin two-dimensional (2D) materials are ideal host systems for quantum defects as they offer easier characterisation, manipulation and read-out of defect states as compared to bulk defects. Here we introduce the Quantum Point Defect (QPOD) dat
This study explored the impact of elevated temperatures on the residual structural properties of concrete made with a non-conventional fine aggregate such as laterite and quarry dust. In regions prone to high temperatures, such as tropical climates, the
