Summary: This article reports the effect of nano-structuring and purity on the thermal and thermoelectric properties of alpha-SrSi2. The results show that nanostructured pellets with a grain size of about 200 nm can be obtained using ball milling and spark plasma sintering, which reduces the lattice contribution to the thermal conductivity. The figure of merit ZT is improved to 0.20 around room temperature after nano-structuring. The influence of Sr purity on the thermoelectric properties is also presented.

Summary: In a recent companion paper, a novel signature of ultralight kinetically mixed dark-photon dark matter was pointed out, which manifests as a quasimonochromatic, time-oscillating terrestrial magnetic field with a specific pattern on Earth's surface. However, despite identifying candidate signals in the SuperMAG dataset, the study did not find robust and significant evidence for a dark-photon dark-matter signal after applying various additional checks to those candidates.

Summary: The synthesis of Quaternary Ni(1-x)CuxFe(2-y)CeyO(4) complex nano-ferrites system with different cerium content ratio and copper substitution degree was achieved using co-precipitation wet chemical technique. The nanoparticles were heated up to 600 degrees C to stabilize the specific crystalline spinel structure, with a limit of cerium content around 0.08 to 0.10. Thermal treatment at 950 degrees C affected phases segregation, with differences in color and size of pelletized samples observed. The study deeply analyzed the cation distribution, crystal structure, morphology, magnetic, and electrical properties of the samples.
