来源：ACS PublicationsCuprous oxide semiconductors have been growing in research interest because of their promising optical and catalytic properties for solar energy conversion. While much recent research has focused on binary and ternary cuprous oxides, the more structurally complex quaternary and higher systems remain significantly less explored. Crystal growth in the cuprous rare-earth (RE) molybdate system has been investigated by using high-temperature and arc-melting synthesis techniques. Prior studies show the formation of two closely related compounds in these systems, occurring as eithe...

来源：ACS PublicationsWe propose to probe the d–f exchange interaction by measuring the response of the itinerant states to an external magnetic field. Two rare-earth monotellurides, TmTe and GdTe, are chosen to demonstrate the mechanism. The thin films of both compounds were prepared by molecular beam epitaxy and studied by scanning tunneling microscopy and spectroscopy. For the TmTe film, the spin degree of freedom of the d-electron exhibits a large response to the magnetic field. For the GdTe film, the magnetic field induces a metal–insulator transition.

来源：ACS PublicationsThe electrochemical production of hydrogen peroxide (H2O2) through the two-electron oxygen reduction reaction (2e– ORR) is a sustainable and practical approach that enables efficient on-site generation and represents an extremely promising strategy for environmentally friendly production. Herein, we synthesized a Bidoped CeO2 (Bi0.1Ce0.9O2) catalyst via a one-step hydrothermal in situ self-assembly method. Both synchrotron radiation X-ray diffraction (SR-XRD) and theoretical calculation analysis demonstrate that Bi doping induces lattice expansion in CeO2 and generates Ce/Bi...

来源：ACS PublicationsCerium copper oxytelluride (CCOT) and lanthanum copper oxytelluride (LCOT) nanomaterials have been synthesized through a straightforward hydrothermal route to explore their potential applications in broadband photodetection and nonlinear optical (NLO) devices. Structural and morphological studies confirmed the successful synthesis of phase-pure, uniformly dispersed nanostructures. The indirect band gaps observed by UV–vis diffuse reflectance spectra (DRS) at 4.06 and 4.07 eV for CCOT and LCOT, respectively, in the visible range. Defect-assisted recombination was studied usin...
