来源：ACS PublicationsCu is extensively used across various fields due to its excellent electrical conductivity, thermal conductivity, and machinability. However, it is prone to corrosion and biofouling in humid and contaminated environments, limiting its performance and durability. Herein, we report a Ce3+-driven electrooxidation method to construct uniform and dense Cu–Ce–O nanorods on ultrathin Cu foil (∼8.7 μm), achieving superhydrophobicity after subsequent fluorination. The incorporation of Ce salts into the electrolyte enables the controllable and rapidly oriented growth of nanorod structu...

来源：ACS PublicationsThe popular Er3+–Yb3+ upconversion (UC) system generates green and red emissions under near-infrared (NIR) 980 nm excitation. The green emission is a two-photon process, whereas for the red emission two and three photon process are both possible, depending on host. Fluoride hosts generally favor a three-photon process because fluorides have low phonon energies and multiphonon relaxation (MPR) involved in the usual two-photon process is suppressed. However, CaF2:Er3+/Yb3+ exceptionally produces an intense two-photon upconverted red emission. Here, we show that the red UC emis...

来源：ACS PublicationsReactions between carbon and lithium hydride in a mixed metal europium/lithium flux led to the synthesis of Eu2Li(C3)H. At room temperature, the compound crystallizes in the tetragonal space group P4/mbm (no. 127, Z = 2; Ca2Li(C3)H type) and undergoes a second-order structural phase transition below ∼250 K to an orthorhombic low-temperature modification (no. 55, Pbam; Z = 4), crystallizing in a new structure type. The phase transition was monitored by using single-crystal X-ray diffraction (SCXRD) and temperature-dependent high-resolution powder diffraction data. Infrared (I...

来源：ACS PublicationsThe binding of rare earth elements to extractants is a key step in their separation and purification by solvent extraction. Classical MD simulations are used to investigate the equilibration configuration and binding dynamics of one, two, and three DEHP– to Er3+ in both bulk water and at the water–dodecane interface. The equilibrium radial distribution function g(r) shows that Er–O and Er–P radial separations within the first and second hydration shells are essentially identical for all bulk and interface simulations, though other aspects of the spatial configuration of hete...
