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...

来源：ACS PublicationsFor next-generation applications, recent developments in sensor fabrication technologies and innovative materials have rendered improved temporal response and spectral detection capabilities feasible. This work demonstrates a dual-mode sensor for simultaneous light and temperature detection. Vacuum thermal evaporation was used to deposit nanostructured polycrystalline TeO2–Li2O–ZnO–Nb2O5–Dy2O3 (TLZND) thin films (∼32 nm crystallites) on monolithic substrates. Field-emission scanning electron microscopy revealed surface morphology and roughness, while Fourier transform infrar...
