Interactions between Methyl Branched-Chain Asymmetric Diglycolamides and Ln3+ Extraction and Spectroscopic and Theoretical Investigations来源：ACS PublicationsDiglycolamides show good selectivity for trivalent lanthanides and actinides and have good application prospects in the treatment of high level liquid waste (HLLW). In this study, two asymmetric diglycolamides with methyl groups at the α-position and β-position of the branched chains were synthesized through a microwave-assisted silane-mediated method: N,N′-dimethyl-N,N′-di(1-methylheptyl) diglycolamide (DMDMHDGA, L1) and N,N′-dimethyl-N,N′...

Triple-Doped Rare-Earth Nanoemitters for Two-Photon 3D Printing of Chip-Scale Polymer Optical Waveguide Amplifiers 来源：ACS PublicationsPolymers with gain media can enable 3D printing of chip-scale optical amplifiers and lasers. In this work, a 3D-printable resin containing uniform dispersion of core/shell erbium–ytterbium–cerium codoped rare-earth nanoparticles (RENPs) is designed, synthesized, and characterized. The core/shell RENPs (NaYF4:Er3+,Yb3+,Ce3+@NaYF4) are synthesized by a high-temperature thermal decomposition method. Uniform dispersion at high concentrations of the RENPs in a 3D pri...

来源：ACS PublicationsMethanol crossover severely limits the performance of direct methanol fuel cells (DMFCs) by introducing methanol to the cathode compartment, where it competes with the oxygen reduction reaction (ORR) and poisons platinum-based ORR electrocatalysts, making it essential to develop methanol-tolerant ORR electrocatalysts. Here, Ni doping is explored as a means of improving the electrocatalytic activity and methanol tolerance of LaCo1–xNixO3 (x = 0, 0.1, 0.15, and 0.2) perovskite oxide electrocatalysts synthesized using a simple sol–gel method. X-ray diffraction (XRD), Fourier tr...

Constructing Electron- and Surface-Structure-Controlled Crystalline/Amorphous Hierarchical NiTe/NiFeCe-LDH Nanoarrays for Efficient Overall Water Splitting 来源：ACS PublicationsConstructing nonprecious metal-based telluride heterointerfaces provides an effective strategy for developing efficient bifunctional catalysts for overall water splitting. However, there still remain major challenges for catalysts that rely on constructing heterojunction interfaces to obtain high-active sites with optimized electronic structures to achieve an efficient oxygen evolution reaction (OER). Herein, hierarchical...
