Applicability of plant-clay mineral composite for rapid algae removal from eutrophic freshwaters at the laboratory and field scales1.

The global issue of water source eutrophication is exacerbated by increasing industrialization and urbanization, posing significant challenges for clean water management. Although strategies such as nutrient management and biomanipulation are employed, these methods often take longer to demonstrate effectiveness and indirectly work on algal blooms. This has led to the evaluation of eco-friendly technologies such as plant-mineral composites (PMCs) for faster and targeted control of algal proliferation and organic pollution.

Enhanced N-type Semiconducting Performance of Asymmetric Monochlorinated Isoindigo-based Semiregioregular Polymers under Dynamic Forces.

The asymmetric monochlorination strategy not only effectively addresses the steric issues in conventional dichlorination but also enables the development of promising acceptor units and semiregioregular polymers. Herein, monochlorinated isoindigo (1CIID) is successfully designed and synthesized by selectively introducing single chlorine (Cl) atoms. Furthermore, the 1CIID copolymerizes with two donor counterparts, centrosymmetric 2,2'-bithiophene (2T) and axisymmetric 4,7-di(thiophen-2-yl)benzo[1,2,5]thiadiazole (DTBT), forming two polymers, P1CIID-2T and P1CIID-DTBT.
