Summary: Efficient removal of antibiotics from the aquatic environment is necessary, and a novel adsorbent called ZC-0.5 was synthesized for the adsorption of sulfamethoxazole (SMX). ZC-0.5 exhibited a high proportion of mesopore and a large specific surface area. It could retain superior maximum adsorption capacities after multiple cycles of adsorption and desorption. The adsorption process followed the pseudo-second-order and mixed first- and second-order kinetic models, and satisfied the Freundlich and Sips isotherm models. Thermodynamic calculation showed that the adsorption process was spontaneous, endothermal, and entropy-increasing. Van der Waals force, electrostatic interaction, hydrophobic force, pi-pi interaction, and hydrogen bond were identified as the plausible adsorption mechanisms.

Summary: In this study, hierarchical porous carbon materials were prepared using cellulose nanocrystals (CNC), phenol-urea-formaldehyde resin, and KOH as templates, carbon sources, and activators, respectively. The CNC templates showed a residue rate of only 5.18% at 800 degrees C, indicating their effectiveness in forming mesopores. The introduction of KOH activation resulted in the formation of micropores, macropores, and small mesopores, leading to a typical hierarchical porous carbon material. The carbon material exhibited a specific capacitance of 194.9 F/g at a current density of 1.0 A/g, with a capacitance retention rate exceeding 74% even at a current density of 40.0 A/g. The assembled supercapacitor showed a capacitance retention rate of over 95% after 10,000 cycles at a current density of 10.0 A/g.

Summary: The development of novel broad-spectrum sterilization is an efficient strategy to combat drug resistance and prevent the abuse of antibiotics in bacterial-infected diseases. Photothermal therapy (PTT) in the second near-infrared (NIR-II) therapeutic window has gained attention in antibacterial applications due to its increased tissue penetration and elevated maximal permissible exposure. However, the lack of bacterial-targeted photothermal agents hinders further development. In this study, we developed three xanthene derivatives (CNs) with intense light harvesting ability around 1180 nm, and CN3 exhibited good NIR-II photothermal and broad-spectrum sterilization against Gram-positive and Gram-negative bacteria.

Summary: The precise engineering of monovalent cations in perovskite materials has led to significant improvements in performance and stability for perovskite light-emitting diodes (PeLEDs). However, the specific role of A-site cations in the electroluminescence (EL) performance and degradation mechanism of PeLEDs remains unclear. This study shows that the commonly used methylammonium cation (MA(+)) has a negative effect on the electrochemical reaction at the perovskite-metal oxide interface, resulting in deteriorated EL performance compared to formamidinium cation (FA(+))-based perovskite. Furthermore, the addition of inorganic cesium cation (Cs+) in a small amount of FA(+) improves crystallinity and crystal size, leading to an optimized peak external quantum efficiency of 21.3% and enhanced stability in PeLEDs.

Summary: In the past decade, halide perovskites have gained significant attention for their excellent properties in optoelectronics. Recently, the discovery of ferroelectricity in halide perovskites has attracted widespread interest. Compared to traditional perovskite oxide ferroelectrics, halide perovskites offer advantages such as structural softness, low weight, and easy processing, making them highly desirable for miniaturization and flexibility in applications. This review focuses on the current research progress in halide perovskite ferroelectrics, including emerging materials systems and their potential applications in ferroelectric photovoltaics, self-powered photodetection, and X-ray detection. The main challenges and potential solutions for the future development of halide perovskite ferroelectric materials are also discussed.

Summary: This paper systematically studied the influence of ionic radius, valence state, surface concentration, and basicity of dopants on the catalytic performance of La2O3 in transesterification of glycerol and dimethyl carbonate. It was found that the ionic radius and valence state of the dopants are the determining factors, while the basic site density is not crucial. Among alkali and alkaline earth metals, 25 mol% Na/La2O3 catalyst achieved the highest glycerol conversion (85%) and glycerol carbonate yield (60%). A plausible mechanism of glycerol and dimethyl carbonate transesterification on Na/La2O3 catalyst has been proposed. This research could help understand the promotional role of alkali metals and alkaline earth metals and guide future design of metal oxide catalysts.

Summary: This study proposes a strategy to achieve large Stokes shifts and high photoluminescence quantum yield in organic metal halide through large cation engineering. Two zero-dimensional antimony(III) chlorides, (TMA)(2)SbCl5 and (TMAA)(2)SbCl5, were designed and synthesized by screening ligands with different cationic volumes. Experimental and theoretical results show that the large cation can promote self-trapped excitons emission and improve stability. The as-prepared (TMAA)(2)SbCl5 microplate exhibits efficient active waveguide with a low loss coefficient of 6.07 x 10(-3) dB mu m(-1) due to its large Stokes shift (291 nm) and high photoluminescence quantum yield (98.3%).

Summary: This study investigates thermo-responsive luminescence in doped Cs2ZnCl4 crystals. The thermal elevation of the orbital state of dopant ions leads to a blueshift of self-trapped exciton (STE) emissions. By examining doped Cs2ZnCl4 crystals, the polyhedral distortion and its effect on luminescence properties are quantitatively addressed. Dual emissions in Sb3+/Mn2+ co-doped Cs2ZnCl4 with distinct luminescence responses to thermal stimuli are synthesized, enabling a new tactic for tunable thermochromic luminescence.
