A Structurally Simple Polymer Donor Enables High-Efficiency Organic Solar Cells with Minimal Energy Losses.
Angew Chem Int Ed Engl
March 2025
South China University of Technology, State Key Laboratory of Luminescent Materials and Devices, Wushan Road 381, 510640, Guangzhou, CHINA.
Energy loss (Eloss) between optical energy gap (Eg) and open-circuit voltage (eVoc) sets efficiency upper limits for organic solar cells (OSCs). Nevertheless, further breaking the limit of Eloss in OSCs is challenging, especially via structurally simple materials in binary OSCs. Herein, a structurally simple non-halogenated polymer donor, namely PBDCT, is developed for realizing high-efficiency OSCs with record-breaking Eloss.

Angew Chem Int Ed Engl
March 2025
Nanjing University of Chinese Medicine, College of Pharmacy, 138, 210023, Nanjing, CHINA.
Although research on the activation of C-H bonds in alkanes has been ongoing for decades, there are still few strategies that are both highly selective and suitable for industrial production. Here, we report a highly selective method for chlorination of terminal C-H bonds in alkanes by combining electrochemistry and organocatalysis. The specific cavity size of organic molecular catalysts ensures high regioselectivity, while the use of inexpensive and easily reusable graphite felt electrodes, simple electrochemical device and mild conditions enables the reaction to maintain good efficiency even when scaled up to kilogram level production.

J Environ Qual
March 2025
College of Science, Inner Mongolia University of Technology, Hohhot, China.
Climate change, driven by greenhouse gas emissions, has emerged as a pressing global ecological and environmental challenge. Our study is dedicated to exploring the various factors influencing greenhouse gas emissions from animal husbandry and predicting their future trends. To this end, we have analyzed data from China's Inner Mongolia Autonomous Region spanning from 1978 to 2022, aiming to estimate the carbon emissions associated with animal husbandry in the region.

March 2025
Shanghai University, Chemistry, Shangda Road 99, 200444, Shanghai, CHINA.
Electrochemiluminescence (ECL) combines electrochemical redox processes with photochemical light emission, offering exceptional sensitivity, spatial control, and stability. Widely applied in biosensing, medical diagnostics, and environmental monitoring, its efficiency often depends on advanced catalytic materials. Single-atom catalysts (SACs), featuring isolated metal atoms dispersed on a support, have emerged as promising candidates due to their unique electronic structures, high atom utilization, and tunable catalytic properties.
