作者： Mengyu Xu Shaocong Yan Ting Liang jia jia Shengjie Yuan Dongxing Kou Zhengji Zhou Wenhui Zhou Yafang Qi Yuena Meng Litao Han Sixin wu Key Laboratory for Special Functional Materials of MOE National & Local Joint Engineering Research Centre for High-efficiency Display and Lighting Technology School of Nanoscience and Materials Engineering Henan University

Solution-processed Cu（In,Ga）Se2（CIGS） solar cells suffer from serious carrier recombination and power conversion efficiency（PCE） loss because of the poor film properties and easy formation of ***, we propose Ag&Se co-selenization strategy to enhance the crystallization and passivate harmful defects of the CIGS films. The formation of Ag-Se phase during the selenization process enables the formation of large grains and suppresses the deep level defects. It is found that Ag doping can enlarge the depletion region width, lower the Urbach energy and prolong the carrier lifetime. As a result, a champion solution-processed CIGS solar cell presents a high efficiency of 16.48% with the highly improved opencircuit voltage（VOC） of 662 m V and fill factor（FF） of 75.8%. This work provides an efficient strategy to prepare high quality solution-processed CIGS films for high-performance CIGS solar cells.

Smart windows with high optical transparency and structural color

引用

Science China Chemistry 2025年

作者： Youtong wu Xueting Li Yiwen Li hao Wang Yuqi Zhang Xihua Lu College of Chemistry and Chemical Engineering Donghua University Fujian Nano-Micro Advanced Materials Sci.& Tech.Co.Ltd. Jinjiang Innovation Entrepreneurship and Creativity Park Shanghai Evanston Advanced Materials Sci.& Tech.Co.Ltd.

In recent years, thermochromic smart windows have played an important role in enhancing energy efficiency and contributing to carbon neutrality in building energy consumption. However, thermal-shielding smart windows with high visible light modulation and structural colors are rarely reported. This study focuses on the development of thermochromic smart windows utilizing poly（N-isopropylacrylamide）(PNIPAm)-based nanogels, which exhibit dynamic solar modulation and high visible light transmission without additional energy input. Unlike traditional electrochromic materials such as tungsten trioxide, these smart windows achieve structural color states through the self-assembly of nanogels, eliminating the need for inorganic materials. The fabricated hydrogel contains thermo-responsive poly（N-isopropylacrylamide-random-acrylic acid-random-N-tert-butyl acrylamide）P（NIPAm-r-AA-r-TBA）(PNTA) nanogels with tunable phase transition temperatures（Tp） that align with ambient *** smart windows demonstrate excellent stability over 100 heating-cooling cycles and significant temperature regulation,achieving an indoor temperature modulation of 10 °C and energy savings of 14.24 KJ m-3compared with normal windows. The production process is simple and scalable, making it feasible for industrial applications. Furthermore, these smart windows offer additional functionalities such as information encryption, adding value to their practical application.

Insufficient MIRO1 contributes to declined oocyte quality during reproductive aging

引用

Science China Life Sciences 2025年

作者： Zhen-Nan Pan hao-Lin Zhang Kun-Huan Zhang jia-Qian Ju Jing-Cai Liu Shao-Chen Sun College of Animal Science and Technology Nanjing Agricultural University Reproductive Medicine Centre The Affiliated Yantai Yuhuangding Hospital of Qingdao University

Mitochondrial Rho-GTPase 1 (MIRO1) is an outer mitochondrial membrane protein which regulates mitochondrial transport and mitophagy in mitosis. In present study, we reported the crucial roles of MIRO1 in mammalian oocyte meiosis and its potential relationship with aging. We found that MIRO1 expressed in mouse and porcine oocytes, and its expression decreased in aged mice. MIRO1 deficiency caused the failure of meiotic resumption and polar body extrusion in both mouse and porcine oocytes, which could be rescued by exogenous MIRO1supplementation. Mass spectrometry data indicated that MIRO1 associated with several cytoskeleton and cell cycle-related proteins, and MIRO1 regulated motor protein Dynein for microtubule-organizing centers (MTOCs) dynamics at germinal vesicle (GV) stage, which determined meiotic resumption. Furthermore, we found that MIRO1 regulated Aurora A and kinesin family member 11 (KIF11) for meiotic spindle assembly in oocytes. Besides, MIRO1 associated with several mitochondria-related proteins dynamic-related protein 1 (DRP1),Parkin and lysosomal-associated membrane protein 2 (LAMP2) for mitochondrial dynamics and mitophagy during oocyte meiosis. Taken together, our results suggested that MIRO1 played pivotal roles in meiotic resumption, spindle assembly and mitochondrial function in mouse and porcine oocytes, and its insufficiency might contribute to the oocyte maturation defects during aging.
