来源：ACS PublicationsElectrochemical water splitting presents a promising method for producing hydrogen, a cleaner and more sustainable fuel. However, its broader application is hindered by the limited availability and high cost of noble metal electrocatalysts, such as platinum, iridium, palladium, and ruthenium, which are known for their efficiency in facilitating water splitting. Rare earth metals, with their distinctive 4f electronic configurations, versatile valencies, robust metal–oxygen interactions, and tunable electronic properties, demonstrate significant potential in reducing energy ba...

来源：pubs.rsc.orgThe synthesis and photophysical properties of tacn- or pyclen-based macrocyclic complexes featuring extended thioanisole-picolinate antennas are reported. These systems efficiently sensitize Eu(III) luminescence, whereas Tb(III) emission is quenched due to back-energy transfer (BET). In all lanthanide-containing complexes (Eu, Tb and Gd), the sulfide donor group was readily oxidized by HOCl to the corresponding sulfoxide or sulfone. Upon oxidation, the Tb(III) complexes became highly luminescent and act as OFF–ON probes when excited at the isosbestic point (302 nm). Finally, a w...

来源：ACS PublicationsSnSe has attracted considerable interest in thermoelectric research owing to its intrinsically low lattice thermal conductivity and distinctive electronic band structure. However, the development of n-type SnSe remains constrained by the low efficiency of electron doping. In this work, a synergistic strategy involving rare-earth element doping and vacancy compensation is employed to enhance the thermoelectric performance of n-type SnSe polycrystals. Rare-earth elements (La, Ce, Nd, and Pr) are systematically investigated as electron dopants. The results indicate that Pr exhi...

来源：ACS PublicationsRelaxor ferroelectric crystals are cornerstone materials for electromechanical and electro-optic technologies, yet the antagonism between piezoelectric performance and optical transparency has persistently impeded device integration. Here, we demonstrate that Sm3+ doping in Pb(Mg1/3Nb2/3)O3–PbTiO3 (PMN-PT) single crystals shatters this conventional compromise, achieving an exceptional piezoelectric coefficient (d33 = 3500 pC/N) by [001]-poling and a large electro-optic coefficient (γc = 700 pm/V) by [110]-poling while retaining 70% optical transmittance across the visible-ne...
