3Manipulating functional groups between polyvinylidene difluoride and nanoparticles for high-performance triboelectric nanogenerator显示文摘Interface functional groups play an essential role in regulating the electrical properties of bulk materials.In this work,we designed a novel strategy to explore a new way to enhance triboelectric performance by regulating the functional groups between nano-fillers and polymer matrix without obvious changes in the dielectric constant.The silica nanoparticles(SNPs)modified perfluoro-silane coupling agents(PFSCAs)with different chain lengths were added to the polyvinylidene difluoride to regulate the transferred charge density(TCD)of triboelectric nanogenerators(TENGs).When the doping concentration of perfluorodecyl modified SNPs is 2.25 wt.%,the nanocomposite film based TENG exhibits the maximum TCD of 166μC/m^(2)and power density of 3.12 W/m^(2)which are 6 times and 39 times as big as those of pure polyvinylidene difluoride(PVDF)film.The charge accumulation and decay process show that interface functional groups dominate the performance of TENGs.Then,a Fermi level model is proposed and why the TCD could be regulated by the concentration of nanoparticles in bulk materials is explained.This work provides a new concept for understanding the performance of TENG independent dielectric constant and points out a new direction for enhancing TENG’s performance,since wealthy functional groups with selectivity are applicable.Zekun Li Lu Zhang Lihao Guo Wenwen Hu Aifang Yu Junyi Zhai 2023Nano Research2023,16,9:1

7A columnar multi-layer sliding triboelectric nanogenerator for water wave energy harvesting independent of wave height and direction显示文摘The ocean,with its highly variable and complex meteorological conditions,harbors enormous renewable resources.Triboelectric nanogenerators(TENGs),which possess unique advantages,show exciting prospects in water wave energy collection.How to design and optimize TENGs to cover all characteristic water wave energies and achieve efficient energy utilization is emergent.In this paper,we carefully designed and fabricated a columnar multi-layer sliding TENG(CMLS-TENG)that can harvest water wave energy independent of wave height and direction.Drive rods with a hollow acrylic spherical shell were introduced to deliver wave energy,ensuring that the CMLS-TENG can work in all directions from 0°to 360°.Based on the sliding structure,switching the optimized CMLS-TENG is independent of wave heights.The optimized CMLS-TENG can achieve a total power density of 730 mW/m^(3) at a wave height of only 4.8 cm regardless of wave direction,which can illuminate multiple light-emitting diodes(LEDs)to provide lighting and provide power to a watch and a hygrometer for temperature and humidity monitoring.This work provides new choices and hopes for the effective collection of full-range water wave energy.Xue Miao Hanxiao Yang Zekun Li Meifei Cheng Yilin Zhao Lingyu Wan Aifang Yu Junyi Zhai 2024Nano Research2024,17,4:0
8乙醛脱氢酶1蛋白在乳腺癌中的预后相关性:96例临床病理学研究(英文)显示文摘Objective: The aim of the study was to investigate the expression and clinical significance of aldehyde dehydrogenase 1 (ALDH1) in breast cancer patients. Methods: The expression of ALDH1 protein was examined by immunohistochemical staining in 96 breast cancer tissues. The disease-free survival analysis of patients was evaluated based on the clinical follow-up data. Results: Expression of ALDH1 protein had significant correlations with ER, PR, and HER2 proteins (P < 0.05), but had no significant correlations with age, tumor size, clinical stage, Pglycoprotein, and lymph node status (P > 0.05). The 2-year disease-free survival rate of ALDH1-positive patients was lower than that of ALDH1-negative patients (P < 0.05). ALDH1-positive patients undergoing chemotherapy and hormonal therapy had lower 2-year disease-free survival rate than ALDH1-negative patients (P < 0.05). Conclusion: ALDH1 expression might play an important role in drug resistant, and ALDH1 may be used as a prognostic marker.Pei Yu Ling Zhou Jianfeng Wang Aifang Jiang Ke Li 2010The Chinese-German Journal of Clinical Oncology2010,9,1:0
9Recent Progress of Functional Fiber and Textile Triboelectric Nanogenerators:Towards Electricity Power Generation and Intelligent Sensing显示文摘Rapid development in wearable electronics has brought huge convenience to human life and gradually penetrated into various indispensable felds,such as health monitoring,medical assistance,smart sports,object tracking and smart home,etc.However,the suitable energy supply system for these wearable electronics remains an important issue to address.Fiber and textile triboelectric nanogenerators(f/t-TENGs),capable of converting biomechanical energy into electricity,have promising features to act as a mobile sustainable power source for wearable electronics or directly serve as an intelligent self-powered sensing solution.Compared with the low-output piezoelectric nanogenerators,hard-to-wear electromagnetic generators and other bulk TENGs,the fber/textile TENG may be the best type of wearable human mechanical energy harvester at present.Herein,this review comprehensively introduces the recent progress of smart fbers and textiles with a highlight on triboelectric nanogenerators,including the general materials and structures of fber/textile shaped electronics,various fber and textile devices for triboelectric/triboelectric-integrated energy harvesting and self-powered smart sensing systems.Moreover,the advance of f/t-TENGs with multifunctionality and large-scale textile processing techniques is summarized as well.Finally,the challenges and perspectives of f/t-TENGs for future improvement,large-scale production and emerging applications are thoroughly discussed as well.Wei Wang Aifang Yu Junyi Zhai Zhong Lin Wang 2021Advanced Fiber Materials2021,3,6:0
