Abstract

After the reported discovery of room-temperature superconductivity at only 1GPa in nitrogendoped lutetium trihydride [1] and the resulting heated discussions, there is an urgent need to reproduce the results and synthesis of this compound. Here, we report the synthesis of stable trigonal LuH3 by hydrogenating pure lutetium which was subsequently pressurised to 2GPa in a dilute-N2/He-rich pressure medium. Raman spectroscopy and X-ray diffraction were used to characterise the structures throughout. After depressurising, energy-dispersive and wavelength-dispersive X-ray spectroscopies were used to characterise the final compound. Though our compound exhibits similar structural behaviour to the Dasenbrock-Gammon et al. sample [1], we do not observe any nitrogen within the structure of the recovered sample at ambient pressure. We observe two cubic structures under pressure that may simultaneously explain the X-ray diffraction and Raman spectra observed: the first corresponds well to Fm-3m LuH2+x, whilst the latter is a novel Ia-3 - type structure., Comment: 8 pages, 3 figures

Abstract

The Forkhead box P2 (FOXP2) is an evolutionary conserved transcription factor involved in the maintenance of neuronal networks, implicated in language disorders. Some evidence suggests a possible link between FOXP2 genetic variability and frontotemporal dementia (FTD) pathology and related endophenotypes. To shed light on this issue, we analysed the association between single-nucleotide polymorphisms (SNPs) in FOXP2 and FTD in 113 patients and 223 healthy controls. In addition, we investigated SNPs in two putative targets of FOXP2, CNTNAP2, Contactin-associated protein-like 2 and PRNP, prion protein genes. Overall, 27 SNPs were selected by a tagging approach. FOXP2-rs17213159-C/T resulted associated with disease risk (OR = 2.16, P = 0.0004), as well as with age at onset and severity of dementia. Other FOXP2 markers were associated with semantic and phonological fluency scores, cognitive levels (MMSE) and neuropsychological tests. Associations with language, cognitive and brain atrophy measures were found with CNTNAP2 and PRNP genetic variability. Overall, although preliminary, results here presented suggest an influence of regulatory pathways centred on FOXP2 as a molecular background of FTD affecting neurological function of multiple brain areas.

48. Fabrication of magnetocaloric La(Fe,Si)$_{13}$ thick films

Abstract

La(Fe,Si)$_{13}$-based compounds are considered to be very promising magnetocaloric materials for magnetic refrigeration applications. Many studies have focused on this material family but only in bulk form. In this paper, we report the fabrication of thick films of La(Fe,Si)$_{13}$, both with and without post-hydriding. These films exhibit magnetic and structural properties comparable to those of bulk materials. We also observe that the ferromagnetic phase transition has a negative thermal hysteresis, a phenomenon not previously found in this material but which may have its origins in the availability of a strain energy reservoir, as in the cases of other materials in which negative thermal hysteresis has been found. Here, it appears that the substrate acts to store strain energy. Our exploratory study demonstrates the viability of thick films of the La(Fe,Si)$_{13}$ phase and motivates further work in the area, while showing that additional perspectives can be gained from reducing the dimensionality of magnetocaloric materials in which the magneto-volume effect is large., Comment: 16 pages, 3 figures

49. Enlarging the magnetocaloric operating window of the Dy2NiMnO6 double perovskite

Abstract

In this paper, we mainly focus on the magnetic and magnetocaloric features of La2-xDyxNiMnO6 double perovskites. Their magnetocaloric properties are investigated in terms of both entropy and adiabatic temperature changes. In contrast to early works, it was found that the Dy2NiMnO6 compound unveils dominant antiferromagnetic interactions under very low magnetic fields. The ordering of its Dy3+ magnetic moments is associated with a giant magnetocaloric effect at very low temperatures, while the established ferromagnetic Ni-O-Mn super-exchange interactions close to 100 K give rise to a moderate magnetocaloric level, only. On the other hand, the doping of Dy2NiMnO6 with high amounts of large-size rare earth elements such as La would enable us to cover an unusually wide magnetocaloric temperature range going from the liquid helium temperature up to room-temperature. More interestingly, the presence of both ordered and disordered ferromagnetic phases in La1.5Dy0.5NiMnO6 maintains constant the isothermal entropy changes over a temperature span of about 200 K, being a favorable situation from a practical point of view., Comment: Accepted for publication in Journal of Physics: D, 2019
