Chiral Luminophore Guided Self-Assembly of Achiral Block Copolymers for the Amplification of Circularly Polarized Luminescence

Sheng-Wei Shao, Puhup Puneet, Ming-Chia Li, Tomoyuki Ikai, Eiji Yashima, and Rong-Ming Ho

This work aims to examine the effect of self-assembly on the chiroptic responses of the achiral block copolymer (BCP) polystyrene-b-poly(ethylene oxide) (PS-b-PEO) associated with chiral luminophores, (R)- or (S)-1,1′-bi-2-naphthol ((R)- or (S)-BINOL), through hydrogen bonding. With the formation of a well-ordered helical phase (H*), significantly induced circular dichroism (ICD) signals for the PEO block in the mixture can be found. Most interestingly, a remarkable amplification with an extremely large dissymmetry factor of luminescence (glum) from 10–3 to 0.3 (i.e., induced circular polarized luminescence (iCPL) behavior) for the chiral BINOLs in the mixture can be achieved by the formation of the helical phase (H*) via mesochiral self-assembly. As a result, by taking advantage of BCP for mesochiral self-assembly, it is feasible to create a nanostructured monolith with substantial optical activities, offering promising applications in the design of chiroptic devices.

Oxygen Vacancies Boosted Hydronium Intercalation: A Paradigm Shift in Aluminum-Based Batteries

Chengxiang Huang, Zhou Jiang, Fuxi Liu, Wenwen Li, Qing Liang, Zhenzhen Zhao, Dr. Xin Ge, Kexin Song, Prof. Lirong Zheng, Xinyan Zhou, Sifan Qiao, Prof. Wei Zhang, Prof. Weitao Zheng

A selective shift in energy storage mechanisms is demonstrated by Wei Zhang, Weitao Zheng et al. in their Communication (e202405592). By meticulously engineering the oxygen vacancies within the α-MoO3 structure, the selective insertion of H3O+ ions (blue droplets) in aqueous aluminum-ion batteries is enabled.

基于亲水性污泥陶粒开展城市黑臭水体生态修复的应用示范

余婷,  曹梦西,  陈路锋,  潘钰,  陈博磊,  冯畅,  熊飞,  梁勇

重建水生植物尤其是沉水植物群落结构，被广泛认为是水体修复治理的有效途径. 目前城市河、湖、渠的黑臭水体治理主要采用截污、清淤等方式，生态功能恢复大多围绕生态浮岛开展浮水、挺水植物的种植，加之城市硬化沟渠等封闭的水系统由于硬化的底质无法种植沉水植物，造成了城市黑臭水体生态修复收效甚微. 本文以江汉大学清源河作为城市硬化沟渠黑臭水体的典型代表，利用亲水性污泥陶粒作“新型土壤”种植苦草(Vallisneria natans (Lour.) H. Hara)，构建“水下森林”生态系统，实现城市黑臭水体的生态原位修复. 种植沉水植物后，沉水植物生物量从241.20 g显著增长至1566.13 g，清源河中水生微型生物的生物多样性显著提升，蓝藻(Cyanobacteria)相对丰度显著降低，总体水质从劣V类提升至近III类，且平稳运行两年未返黑臭. 该应用示范体系中，亲水性污泥陶粒一方面为苦草提供固着基质，实现了无底泥硬化沟渠中沉水植物的种植和生长，另一方面可为水生微型生物提供栖息地. 清源河示范治理工程应用亲水性污泥陶粒开展城市黑臭水体生态修复，不仅将城市生态系统中的污泥烧制成陶粒后回用到淡水生态系统的修复，同时实现污泥的无害化和资源化的循环利用，为城市黑臭水体的修复及生态重构和国家达成“碳中和”目标提供了新思路.
