来源：X-MOLThermochemical energy storage (TCES) systems are gaining widespread consideration to increase the dispatchability of renewable energies. Reduction/oxidation of metal oxides has the advantage that air can be used during both reaction steps, simplifying the process scheme. Copper oxide is an interesting candidate, thanks to its high reaction heat and low toxicity, but it suffers from strong sintering at high temperatures because of the low melting point of Cu2O. This work investigates the use of copper/cerium mixed oxides to reduce sintering phenomena, in order to allow their use in TCES...

来源：X-MOLLanthanum, a rare earth element that is relatively common in the earth's crust. Its role in plant-pathogen interactions, particularly with root-knot nematodes, remains to be investigated. To address this lack of knowledge, tomato plants were treated with different concentrations of LaCl3 (20 μM, 40 μM, 60 μM, and 100 μM), and the day after, they were inoculated with root-knot nematode. The highest reduction in the number of galls and nematodes was recorded when LaCl3 was treated at a concentration of 100 μM, and the experiment was repeated twice independently. The time line monitor...

来源：ACS PublicationsA series of NaRESe2 (RE = Sm, Gd–Lu) compounds were synthesized as single crystals, and NaRESe2 (RE = Ce, Pr, Nd) was synthesized as polycrystalline powders using the boron chalcogen mixture (BCM) method. The detailed synthesis, single-crystal structure characterization, magnetic properties, and optical properties of the NaRESe2 series are reported. The structures of the crystals were characterized by single-crystal X-ray diffraction. This series crystallizes in the trigonal (R̅3m) crystal system, where the RE3+ ions form a triangular lattice. Magnetic property measurements ...

来源：ACS PublicationsHighly polar solvents are generally considered to significantly quench the luminous emission of rare-earth doping luminescence materials. In this work, we reported a counterintuitive luminescence phenomenon in Dy/Eu@Gd-MOFs. Their photoluminescence (PL) behaviors in propanol/butanol isomers exhibit trends of emission intensity that inversely correlate with solvent polarity. This phenomenon should not be simplistically ascribed to quenching induced solely by reabsorption, solvent effects, or high-frequency vibrational groups. The structural differences among propanol and buta...
