Polysaccharide-based cyanide-bridged bimetallic coordination polymers (PCBPs) were developed for simultaneous Tl(I) and Tl(III) removal, achieving a maximum adsorption rate of 98.3% after 180 minutes. The stable adsorption efficiency of Tl could be maintained in a wide range of pH, and even in the presence of interfering high-intensity cations and total organic matter, PCBPs showed excellent Tl removal efficiency. The amphoteric structure of PCBPs provided many chemical chelation sites, significantly improving the adsorption capacity for Tl.

Summary: Uranium mining and nuclear energy production generate large amounts of uranium-containing radioactive wastewater. Silicate minerals such as halloysite nanotubes enriched in Fe, Al, and Si have properties suitable for treating this wastewater. In this study, nanorod composites of halloysite nanotubes loaded with alpha-Fe2O3 and Fe3O4 were used to adsorb uranyl ions. The equilibrium adsorption was achieved within a short contact time, and the maximum adsorption capacities were 74.64 mg/g and 66.40 mg/g for He-HNTs and Ma-HNTs, respectively. Ma-HNTs showed excellent magnetic separation performance for uranium-containing radioactive wastewater. The sequestration behavior of U(VI) on He-HNTs and Ma-HNTs was dominated by ion exchange, surface complexation, and electrostatic interactions. Reduction processes contributed to greater U(VI) removal efficiency in the Ma-HNTs-U(VI) system. The iron oxide-halloysite composites hold great promise for treating uranium(VI)-containing wastewater.

Summary: Two-dimensional, high-quality perylene single crystals were successfully grown using a space-confined strategy method. The films exhibited alpha form crystallization, which was confirmed through various techniques. The optical absorption measurements showed strong anisotropy and excellent agreement with literature data, while the field-effect transistor's anisotropic mobility data demonstrated high crystalline order. Momentum-dependent studies using electron energy-loss spectroscopy revealed negative dispersion of the first exciton along the crystal b direction, with an exciton bandwidth of 72 meV. The observed behavior is believed to be a result of charge-transfer exciton coupling between perylene dimers in the unit cell.

Summary: This article presents the results of a systematic study on the electrochemical performance and mechanical changes in two types of commercial batteries with different anode chemistry. The study reveals that the swelling of anode layers in batteries with silicon-based components causes deformations in the jelly roll structure, but the presence of a small percentage of silicon does not significantly impact the cycling performance of the cells within the relevant state-of-health range for electric vehicles (EVs). The research suggests that there is room for improving the cell capacities by increasing the silicon loading in composite anodes to meet the increasing demands on EVs.

Summary: By coupling electrochemical testing to operando synchrotron based X-ray absorption and powder diffraction experiments, blended positive electrodes consisting of LiMn2O4 spinel (LMO) and layered LiNi0.5Mn0.3Co0.2O2 (NMC) were studied to understand their redox mechanism. It was found that blending NMC with LMO can enhance energy density at high rates, with the blend containing 25% LMO showing the best performance. Testing with a special electrochemical setup revealed that the effective current load on each blend component can vary significantly from the nominal rate and also changes with SoC. Operando studies allowed monitoring of the oxidation state evolution and changes in crystal structure, in line with the expected behavior of individual components considering their electrochemical current loads.
