Electrochemical cells employing Sodium (Na) and Zinc (Zn) electrodes and a chloride salt electrolyte have been imaged by neutron radiography during cycling. The use of such abundant raw materials confers a very low energy-normalised cost to…

In the framework of physics experiments searching for rare events, the selection of extremely radiopure materials is a challenging task, as the signal of interest is often hidden by instrumental background. Neutron activation is a powerful…

Using two different full-potential ab-initio techniques we introduce a simple, universal rule based on the number of broken first-neighbor bonds to determine the surface energies of the three noble metals Cu, Ag and Au. When a bond is…

Many choices are available in order to evaluate large radioactive decay networks. %multi-particle decay data. There are many parameters that influence the calculated $\beta$-decay delayed single and multi-neutron emission branching…

Until recently, all known ordered II-IV-N2 materials crystallised in the $\beta$-NaFeO$_2$-type in space group Pna2$_1$. BeGeN$_2$, however, crystallises in space group Pmc2$_1$, with a different cation ordering motif long anticipated for…

Ba2MnTeO6 was first characterised using X-ray diffraction and reported to show a small distortion1 from the idealised cubic perovskite which displays face-centred cubic arrangement of Mn2+. A recent report has asserted that this leads to a…

This study investigates the scintillation properties of polycrystalline diamond for particle detection applications, particularly in neutron and alpha radiation environments. Polycrystalline diamonds provide a cost-effective alternative to…

The comparison of magnetic moments of neutron and proton reveals three possible states of a nucleon each composed of quark plus diquark. In this scheme for the quark content uds there should be three baryons with a different structure:…

The neutron-deficient Ca isotopes continue to attract attention due to their importance for testing isospin symmetry and their relevance in capture reactions of interest for nova nucleosynthesis and the shape of light curves in Type I X-ray…

It has now become recognised that damped Lyman alpha systems play an important role in helping us unravel the origin of chemical elements. In this presentation, we describe the main results of a recently completed survey of the most…

The growing interest in clarifying the controversial situation in the Dark Matter sector has driven the experimental efforts towards new ways to investigate the long-standing DAMA/LIBRA result. Among them, low-temperature calorimeters based…

The CAFAna framework, initially developed for oscillation analysis with NOvA, is now a key tool in the NOvA, SBN, and DUNE experiments for day-to-day analysis and the production of final oscillation results.
