Flexible,breathable,and highly sensitive pressure sensors have increasingly become a focal point of interest due to their pivotal role in healthcare monitoring,advanced electronic skin applications,and disease diagnosis.However,traditional methods,involving elastomer film-based substrates or encapsulation techniques,often fall short due to mechanical mismatches,discomfort,lack of breathability,and limitations in sensing abilities.Consequently,there is a pressing need,yet it remains a significant challenge to create pressure sensors that are not only highly breathable,flexible,and comfortable but also sensitive,durable,and biocompatible.Herein,we present a biocompatible and breathable fabric-based pressure sensor,using nonwoven fabrics as both the sensing electrode(coated with MXene/poly(3,4-ethylenedioxythiophene):polystyrene sulfonate[PEDOT:PSS])and the interdigitated electrode(printed with MXene pattern)via a scalable spray-coating and screen-coating technique.The resultant device exhibits commendable air permeability,biocompatibility,and pressure sensing performance,including a remarkable sensitivity(754.5 kPa^(−1)),rapid response/recovery time(180/110 ms),and robust cycling stability.Furthermore,the integration of PEDOT:PSS plays a crucial role in protecting the MXene nanosheets from oxidation,significantly enhancing the device's long-term durability.These outstanding features make this sensor highly suitable for applications in fullrange human activities detection and disease diagnosis.Our study underscores the promising future of flexible pressure sensors in the realm of intelligent wearable electronics,setting a new benchmark for the industry.

With the increasing concern of energy crisis and global warming,the whole globe is in an urgent need to develop clean energy that comes from renewable sources and does not harm the environment to fulfill the carbon neutralization and green earth commitments.Water is the most abundant substance on earth and has been historically used as the major energy carriers in watermill,water wheel,hydroelectricity.Moisture electricity generation is another emerging technology that can convert lowgrade energy in the widely-accessible moisture to electricity simply by the integration of moisture,electrodes,deliberatelydesigned hygroscopic films.Recent research on moisture electricity generators(MEGs)led to the creation of a series of selfpowered sensors and in some occasions they have replaced conventional batteries to power miniaturized devices.In this review,the basic mechanisms of MEGs are firstly clarified,three categories of them,i.e.,gradient structure,homogeneous structure,and heterogeneous structure depending on the structure of hygroscopic films,are then introduced.Furthermore,recent advances in the fabrication,characteristics,performance of MEGs are summarized,MEGs with continuous or transient output that could be applied in self-powered sensors and power sources are discussed.Finally,some remaining challenges and our perspectives on MEGs are highlighted.

Biosurface and Biotribology 2022年第3期8卷 199-211页

作者： Chen Chen Haiyang Zhan Xiangge Bai Zichao Yuan Lei Zhao yahua liu Shile Feng Key Laboratory for Precision&Non‐traditional Machining Technology of Ministry of Education Dalian University of TechnologyDalianChina

Superhydrophobic surfaces(SHSs)exist in many biological organisms endowed by spectacular surface topographies,which provide important insights to drive a paradigm shift in design of engineering surfaces.Based on this,extensive progresses have been developed on bionic superhydrophobic strategies.Among them,SHSs based on topography of copper oxides exhibit considerable application prospects because of the steerability and diversity of topography,as well as additional performances,such as antibiosis,anticorrosion and catalysis.We first present a brief overview of the discovery of natural SHSs as well as fundamental understanding of surface wetting performance.Then,the structural effects in superhydrophobic systems based on the topographies of biological organisms and copper oxides are described.Finally,we highlight the perspectives on the novel design strategies of copper oxide‐based SHSs that adapt to various practical applications.

Biosurface and Biotribology 2019年第2期5卷 35-45页

作者： yahua liu Xiantong Yan Zuankai Wang Key Laboratory for Precision&Non-Traditional Machining Technology of Ministry of Education Dalian University of TechnologyDalian 116024People’s Republic of China Department of Mechanical Engineering City University of Hong KongHong Kong 999077People’s Republic of China

The dynamic interaction of droplets with slippery surfaces is essential to various industrial applications,such as anti-icing,water-repellency or water-harvesting,anti-bacterial,and phase change heat transfer.With recent progress in materials,manufacturing as well as learning from nature,the physics of droplet dynamics has been greatly enriched owing to the emergence of peculiar wetting states manifested on bio-inspired textured surfaces.This review is devoted to the discussion of the recent progress made in the authors’understanding of the dynamic interaction of small droplets with bio-inspired surfaces.Particular attention is given to droplet impact on slippery surfaces,such as superhydrophobic surfaces characterised with air-solid-liquid triple-phase interface and slippery lubricant infused porous surfaces characterised with the liquid/liquid two-phase interface.Droplet spreading,retraction,contact time,elastodynamics as well as oblique impact are systematically reviewed.Finally,the authors offer their perspectives on this important and highly multidisciplinary research area.

Science China Chemistry 2018年第9期61卷 1062-1087页

作者： Jiahui Zhou Peipei Zuo yahua liu Zhengjin Yang Tongwen Xu CAS Key Laboratory of Soft Matter Chemistry Collaborative Innovation Center of Chemistry for Energy Materials School of Chemistry and Materials Science University of Science and Technology of China

Ion exchange membranes(IEMs) play a significant role in fields of energy and environment, for instance fuel cells, diffusion dialysis, electrodialysis, etc. The limited choice of commercially available IEMs has produced a strong demand of fabricating IEMs with improved properties via facile synthetic strategies over the past two decades. Poly(phenylene oxide)(PPO) is considered as a promising polymeric material for constructing practical IEMs, due to its advantages of good physicochemical properties, low manufacturing cost and easy post functionalization. In this review, we present the accumulated efforts in synthetic strategies towards diverse types of PPO-based IEMs. Relation between polymer structures and the resulted features is discussed in detail. Besides, applying IEMs from PPO and its derivatives in fuel cell, diffusion dialysis and electrodialysis is summarized and commented.

Metastasis remains the primary cause for mortality of breast cancer.Despite advances in current therapeutic agents,patients with metastatic breast cancer still have poor prognoses.Tumor hypoxia,a key microenvironment factor,is emerging as an attractive target to prevent metastasis and is also involved with resistance to phototherapy.Here,we show an effective nanotherapeutic approach based on manganese dioxide-coated polydopamine nanocarriers to trigger robust anti-tumor and anti-metastasis responses against metastatic breast cancer by supplemental oxygenation and multimodal imaging-guided phototherapies.In cancer cells,the produced oxygen by the developed nanoplatform decreases the expression of hypoxia-inducible factors 1 a to inhibit tumor metastasis,and enhances the efficacy of photodynamic therapy.This nanotherapeutic approach enables the combined photodynamic/photothermal treatments with great inhibition on cell migration and invasion in vitro.Moreover,the nanotherapeutics effectively suppresses primary tumor progress and inhibits lung metastasis in v ivo in a breast cancer mouse model with satisfying biosafety.This study suggests that the tumor hypoxia-targeting nanotherapeutics have great potential for preventing and treating metastatic cancers.

Eu-based anolytes for high-voltage and long-lifetime aqueous flow batteries

引用

Journal of Energy Chemistry 2021年第9期30卷 368-375页

作者： Pan Sun yahua liu Peipei Zuo Yuanyuan Li Qianru Chen Zhengjin Yang Tongwen Xu CAS Key Laboratory of Soft Matter Chemistry iCHEM(Collaborative Innovation Center of Chemistry for Energy Materials)Department of ChemistrySchool of Chemistry and MaterialsUniversity of Science and Technology of ChinaHefei 230026AnhuiChina Dalian National Laboratory for Clean Energy Dalian 116023LiaoningChina

Aqueous flow batteries(AFBs) are among the most promising electrochemical energy storage solutions for the massive-scale adoption of renewable electricity because of decoupled energy and power, design flexibility, improved safety and low cost. The development of high-voltage AFB is, however, limited by the lack of stable anolytes that have low redox potential. Here we report Eu-based anolytes for high-voltage p H-neutral AFB applications. Eu^(3+) has a reduction potential of -0.39 V vs. SHE, which can be dramatically lowered when forming stable complex with inexpensive organic chelates. A typical complex, Eu DTPA,features a low redox potential of -1.09 V vs. SHE, fast redox kinetics, and a high water solubility of 1.5 M. When paired with ferrocyanide, the battery had an open-circuit voltage of 1.56 V and demonstrated stable cell cycling performance, including a capacity retention rate of 99.997% per cycle over500 cycles at 40 m A cm^(-2), a current efficiency of >99.9%, and an energy efficiency of >83.3%. A high concentration anolyte at 1.5 M exhibited a volumetric capacity of 40.2 Ah L^(-1), which is one of the highest known for p H-neutral AFBs, promising a potent solution for the grid-scale storage of renewable electricity.

Chinese Journal of Chemistry 2013年第5期31卷 684-688页

作者： Lingwei Kong Mingliang Ma Xiaoli Zhao yahua liu Xianqiang Mi Biao Jiang Ke Wen ~hanghai Engineering Research Center of Molecular Therapeutics and New Drug Development East China Nor- mal University Shanghai 200062 China Shanghai Key Laboratory of Green Chemistry and Chemical Processes and Department of Chemistry East China Normal University Shanghai 200062 China Medicinal Chemistry ChemBridge Research Laboratories Inc.

Tetraamido-oxacalix[4]arene derivatives have been synthesized via the reactions of tetraamino-oxacalix[4]arene with excess butyryl chloride, octanoyl chloride, benzoyl chloride and p-toluenesulfonyl chloride, respectively. JH NMR results suggest that these oxacalix[4]arene derivatives preferentially adopt the 1,3-alternate （saddle-like） con- formation in solution, which were also the case in the solid state as demonstrated by single crystal X-ray analysis. A dimerized slipped capsule could be formed by tetra-butyramido-oxacalix[4]arene in the solid state via intermolecu- lar hydrogen bond interactions under the assistance of two encapsulated methanol molecules. On the other hand, a molecular cavity was formed by tetra-p-toluenesulfonamido-oxacalix[4]arene which can encapsulate a solvent molecule of ethyl acetate.
