Ta2O5 mechanical losses seem to be the main cause of mirror thermal noise, limiting current interferometric gravitational wave detectors sensitivity in the 50-300 Hz frequency range. Work is in progress for the identification of these relaxation processes probably related with lattice defects and impurities that are distributed both in the...

The realization of a stable lithium-metal free (LiMF) sulphur battery based on amorphous carbon anode and lithium sulphide (Li2S) cathode is here reported. In particular, a biomass waste originating full-cell combining a carbonized brewer's spent grain (CBSG) biochar anode with a Li2S-graphene composite cathode (Li2S70Gr30) is proposed. This...

We show how, in the synthesis of yellow-emissive Bi-doped Cs2Ag1–xNaxInCl6 double perovskite nanocrystals (NCs), preventing the transient formation of Ag0 particles increases the photoluminescence quantum yield (PLQY) of the NCs from ∼30\% to ∼60\%. Calculations indicate that the presence of even a single Ag0 species on the surface of a NC...

Ion migration is associated with hysteresis observed in halide perovskite-based solar cells and light-emitting diodes, however, it is crucial for their effective performance in memory devices. In the halide perovskites field, a direct link between the average/local structure and the preferred ion migration hopping pathway has yet to be...

Phase-pure CsSnI3, FASnI3, Cs(PbSn)I3, FA(PbSn)I3 perovskites (FA ¼ formamidinium ¼ HC(NH2)2 þ) as well as the analogous so-called vacancyordered double perovskites Cs2SnI6 and FA2SnI6 are mechanochemically synthesized. The addition of SnF2 is found to be crucial for the synthesis of Cs-containing perovskites but unnecessary for hybrid ones....

Cadmium mercury selenide (CdHgSe) nanocrystals exhibit a unique combination of low-energy optical absorption and emission, which can be tuned from the visible to the infrared range through both quantum confinement and adjustment of their composition. Owing to this advantage, such nanocrystals have been studied as a promising narrow-band...
