| 2 | Microwave absorbing properties and magnetic properties of different carbon nanotubes显示文摘The microwave absorbing properties and magnetic properties of as-grown Fe-filled carbon nanotubes (CNTs), annealed Fe-filled CNTs, and multi-walled CNTs were studied. Vibrating sample magnetometer results showed that the annealed Fe-filled CNTs have the weakest coercivity and strongest saturation magnetization among the three types CNTs, due to the presence of more ferromagnetic α-Fe nanowires. After annealing, the values increased to 291.0 Oe and 28.0 emu/g and the samples showed excellent microwave absorbing properties. The reflection loss was over 5 dB between 11.6 GHz and 18 GHz with a maximum value of 10.8 dB for annealed Fe-filled CNTs (1.1 wt%)/epoxy composite. | XuChun Gui KunLin Wang JinQuan Wei RuiTao Lü QinKe Shu Yi Jia Chen Wang HongWei Zhu DeHai Wu | 2009 | Science China(Technological Sciences)2009，52，1： | 6 |
| 3 | Multiscale nanowire-microfluidic hybrid strain sensors with high sensitivity and stretchability显示文摘Nanomaterials with low-dimensional morphology have been explored for enhancing the performance of strain sensors,but it remains difficult to achieve high stretchability and sensitivity simultaneously.In this work,a composite structure strain sensor based on nanomaterials and conductive liquid is designed,demonstrated,and engineered.The nanowire-microfluidic hybrid(NMH)strain sensor responds to multiscale strains from 4%to over 400%,with a high sensitivity and durability under small strain.Metal nanowires and carbon nanotubes are used to fabricate the NMH strain sensors,which simultaneously exhibit record-high average gauge factors and stretchability,far better than the conventional nanowire devices.Quantitative modeling of the electrical characteristics reveals that the effective conductivity percolation through the hybrid structures is the key to achieving high gauge factors for multiscale sensing.The sensors can operate at low voltages and are capable of responding to various mechanical deformations.When fixed on human skin,the sensors can monitor large-scale deformations(skeleton motion)and small-scale deformations(facial expressions and pulses).The sensors are also employed in multichannel,interactive electronic system for wireless control of robotics.Such demonstrations indicate the potential of the sensors as wearable detectors for human motion or as bionic ligaments in soft robotics. | Songjia Han Chunrui Liu Huihua Xu Dongyuan Yao Kanghong Yan Huanliang Zheng Hui-Jiuan Chen Xuchun Gui Sheng Chu Chuan Liu | 2018 | npj Flexible Electronics2018，2，1： | 6 |
| 4 | Humidity Sensing of Stretchable and Transparent Hydrogel Films for Wireless Respiration Monitoring显示文摘Respiratory monitoring plays a pivotal role in health assessment and provides an important application prospect for flexible humidity sensors.However,traditional humidity sensors suffer from a trade-off between deformability,sensitivity,and transparency,and thus the development of high-performance,stretchable,and low-cost humidity sensors is urgently needed as wearable electronics.Here,ultrasensitive,highly deformable,and transparent humidity sensors are fabricated based on cost-effective polyacrylamide-based double network hydrogels.Concomitantly,a general method for preparing hydrogel films with controllable thickness is proposed to boost the sensitivity of hydrogel-based sensors due to the extensively increased specific surface area,which can be applied to different polymer networks and facilitate the development of flexible integrated electronics.In addition,sustainable tapioca rich in hydrophilic polar groups is introduced for the first time as a second cross-linked network,exhibiting excellent water adsorption capacity.Through the synergistic optimization of structure and composition,the obtained hydrogel film exhibits an ultrahigh sensitivity of 13,462.1%/%RH,which is unprecedented.Moreover,the hydrogel film-based sensor exhibits excellent repeatability and the ability to work normally under stretching with even enhanced sensitivity.As a proof of concept,we integrate the stretchable sensor with a specially designed wireless circuit and mask to fabricate a wireless respiratory interruption detection system with Bluetooth transmission,enabling real-time monitoring of human health status.This work provides a general strategy to construct high-performance,stretchable,and miniaturized hydrogel-based sensors as next-generation wearable devices for real-time monitoring of various physiological signals. | Yuning Liang Qiongling Ding Hao Wang Zixuan Wu Jianye Li Zhenyi Li Kai Tao Xuchun Gui Jin Wu | 2022 | Nano-Micro Letters2022，14，11： | 5 |
| 5 | Ultrathin, Lightweight, and Flexible CNT Buckypaper Enhanced Using MXenes for Electromagnetic Interference Shielding显示文摘Lightweight,flexibility,and low thickness are urgent requirements for next-generation high-performance electromagnetic interference(EMI)shielding materials for catering to the demand for smart and wearable electronic devices.Although several efforts have focused on constructing porous and flexible conductive films or aerogels,few studies have achieved a balance in terms of density,thickness,flexibility,and EMI shielding effectiveness(SE).Herein,an ultrathin,lightweight,and flexible carbon nanotube(CNT)buckypaper enhanced using MXenes(Ti3C2Tx)for high-performance EMI shielding is synthesized through a facile electrophoretic deposition process.The obtained Ti3C2Tx@CNT hybrid buckypaper exhibits an outstanding EMI SE of 60.5 dB in the X-band at 100μm.The hybrid buckypaper with an MXene content of 49.4 wt%exhibits an EMI SE of 50.4 dB in the X-band with a thickness of only 15μm,which is 105%higher than that of pristine CNT buckypaper.Furthermore,an average specific SE value of 5.7×10^(4) dB cm^(2) g^(−1) is exhibited in the 5-μm hybrid buckypaper.Thus,this assembly process proves promising for the construction of ultrathin,flexible,and high-performance EMI shielding films for application in electronic devices and wireless communications. | Rongliang Yang Xuchun Gui Li Yao Qingmei Hu Leilei Yang Hao Zhang Yongtao Yao Hui Mei Zikang Tang | 2021 | Nano-Micro Letters2021，13，4： | 2 |
| 6 | Stretchable, self‐healable, and breathable biomimetic iontronics with superior humidity‐sensing performance for wireless respiration monitoring显示文摘Stretchable,self‐healing,and breathable skin‐biomimetic‐sensing iontronics play an important role in human physiological signal monitoring and human–computer interaction.However,previous studies have focused on the mimicking of skin tactile sensing(pressure,strain,and temperature),and the development of more functionalities is necessary.To this end,a superior humidity‐sensitive ionic skin is developed based on a self‐healing,stretchable,breathable,and biocompatible polyvinyl alcohol–cellulose nanofibers organohydrogel film,showing a pronounced thickness‐dependent humidity‐sensing performance.The as‐prepared 62.47‐μm‐thick organohydrogel film exhibits a high response(25,000%)to 98%RH,excellent repeatability,and long‐term stability(120 days).Moreover,this ionic skin has excellent resistance to large mechanical deformation and damage,and the worn‐out material can still retain its humidity‐sensing capabilities after self‐repair.Humidity‐sensing mechanism studies show that the induced response is mainly related to the increase of proton mobility and interfacial charge transport efficiency after water adsorption.The superior humidity responsiveness is attributed to the reduced thickness and the increased specific surface area of the organohydrogel film,allowing real‐time recording of physiological signals.Notably,by combining with a self‐designed printed circuit board,a continuous and wireless respiration monitoring system is developed,presenting its great potential in wearable and biomedical electronics. | Qiongling Ding Hao Wang Zijing Zhou Zixuan Wu Kai Tao Xuchun Gui Chuan Liu Wenxiong Shi Jin Wu | 2023 | SmartMat2023，4，2： | 2 |

| 10 | Actively logical modulation of MEMS-based terahertz metamaterial显示文摘The integration of micro-electro-mechanical system (MEMS) with metamaterial has provided a novel route to achieve programmability via its reconfigurable capabilities. Here,we propose and demonstrate a MEMS-based metadevice by using switchable winding-shaped cantilever metamaterial (WCM) for active logical modulation.WCM can be actuated by external driving voltage,and the logical modulation bit is performed by releasing MEMS cantilevers to represent 'on' and 'off' states. While the underneath substrate surface of a MEMS-based metadevice is rough after releasing the cantilevers,the metadevice is allowed to operate on the reconfigurable switching state and avoid the snapping down of the device when the system is overloaded. Such a reconfigurable and programmable MEMS-based metadevice exhibits multifunctional characteristics to simultaneously perform the logic operations of 'OR' and 'AND' gates. By exploiting the tuning mechanism of the MEMS-based metadevice,the arbitrary metamaterial configuration can be implanted into WCM. This opens a wide avenue to further enlarge the operating frequency range and applications in optoelectronic fields. These unique results provide various possibilities in multifunctional switching,active logical modulating,and optical computing applications. | RUIJIA XU XIAOCAN XU BO-RU YANG XUCHUN GUI ZONG QIN YU-SHENG LIN | 2021 | Photonics Research2021，9，7： | 1 |

| 12 | Light emission of double-walled carbon nanotube filaments doped with yttrium and europium显示文摘As the potential applications of carbon nanotubes in the field of electroluminescence, elements yttrium and europium were introduced to modify the emission properties of double-walled carbon nanotubes (DWNTs) to obtain higher efficacy and other properties. The light emission spectrum of the Y-Eu-doped DWNT filament is suppressed in the near-infrared range, while enhanced in the mid-infrared range. The doped DWNT filament can reach higher efficacy than that of the pure DWNT filament at the same input power and can work stably as long as 5000 h at 12 V. These filaments could be useful for the light sources with special functions, such as infrared light sources operated at low input power. | SHU QinKe WANG KunLin WEI JinQuan ZHU HongWei LI XinMing CHEN Xi JIA Yi GUI XuChun XU ErYang WU DeHai | 2009 | Science China(Technological Sciences)2009，52，1： | 1 |

| 16 | Engineering Smart Composite Hydrogels for Wearable Health Monitoring显示文摘Growing health awareness triggers the public's concern about health problems. People want a timely and comprehensive picture of their condition without frequent trips to the hospital for costly and cumbersome general check-ups. The wearable technique provides a continuous measurement method for health monitoring by tracking a person's physiological data and analyzing it locally or remotely.During the health monitoring process,different kinds of sensors convert physiological signals into electrical or optical signals that can be recorded and transmitted, consequently playing a crucial role in wearable techniques. Wearable application scenarios usually require sensors to possess excellent flexibility and stretchability. Thus, designing flexible and stretchable sensors with reliable performance is the key to wearable technology. Smart composite hydrogels, which have tunable electrical properties, mechanical properties, biocompatibility, and multi-stimulus sensitivity, are one of the best sensitive materials for wearable health monitoring. This review summarizes the common synthetic and performance optimization strategies of smart composite hydrogels and focuses on the current application of smart composite hydrogels in the field of wearable health monitoring. | Jianye Li Qiongling Ding Hao Wang Zixuan Wu Xuchun Gui Chunwei Li Ning Hu Kai Tao Jin Wu | 2023 | Nano-Micro Letters2023，15，7： | 0 |
| 17 | Flexible, Transparent and Conductive Metal Mesh Films with Ultra‑High FoM for Stretchable Heating and Electromagnetic Interference Shielding显示文摘Despite the growing demand for transparent conductive films in smart and wearable electronics for electromagnetic interference(EMI)shielding,achieving a flexible EMI shielding film,while maintaining a high transmittance remains a significant challenge.Herein,a flexible,transparent,and conductive copper(Cu)metal mesh film for EMI shielding is fabricated by self-forming crackle template method and electroplating technique.The Cu mesh film shows an ultra-low sheet resistance(0.18Ω□^(-1)),high transmittance(85.8%@550 nm),and ultra-high figure of merit(>13,000).It also has satisfactory stretchability and mechanical stability,with a resistance increases of only 1.3%after 1,000 bending cycles.As a stretchable heater(ε>30%),the saturation temperature of the film can reach over 110°C within 60 s at 1.00 V applied voltage.Moreover,the metal mesh film exhibits outstanding average EMI shielding effectiveness of 40.4 dB in the X-band at the thickness of 2.5μm.As a demonstration,it is used as a transparent window for shielding the wireless communication electromagnetic waves.Therefore,the flexible and transparent conductive Cu mesh film proposed in this work provides a promising candidate for the next-generation EMI shielding applications. | Zibo Chen Shaodian Yang Junhua Huang Yifan Gu Weibo Huang Shaoyong Liu Zhiqiang Lin Zhiping Zeng Yougen Hu Zimin Chen Boru Yang Xuchun Gui | 2024 | Nano-Micro Letters2024，16，5： | 0 |
| 18 | Patternable and transferable silver nanowire conductors via plasma-enhanced cryo-transferring process towards highly stretchable and transparent capacitive touch sensor array显示文摘Stretchable transparent electrode(STE)plays a key role in numerous emerging applications as an indispensable component for future stretchable devices.The embedded STE,as a promising candidate,possesses balanced performances and facile preparation procedures.However,it still suffers from the defects of conductive materials caused by the transferring,which results in the irreversible failure of devices.In this work,a patternable silver nanowire(AgNW)STE was fabricated by a plasma-enhanced cryo-transferring(PEC-transferring)process.Owing to the plasma-induced sintering,the AgNW network obtained remarkable improvement in robustness,which ensured the intact network after transferring and thus led to superior tensile electrical properties of the STE.Furthermore,serpentine patterns were utilized to optimize the tensile electrical properties of the STE,which achieved a figure of merit of 292.8 and 150%resistance changing under 50%strain.As a practical application,a 4×3 array of the mutual-capacitive type stretchable touch sensors was demonstrated for future touch sensors in stretchable devices.The PEC-transferring process opened a new avenue for patternable embedded STEs and exhibited its high potential in wearable electronics and the Internet of Thing devices. | Yifan Gu Zhiguang Qiu Simu Zhu Hao Lu Lisha Peng Gaofan Zhang Ziyi Wu Xuchun Gui Zong Qin Bo-ru Yang | 2023 | Nano Research2023，16，8： | 0 |
| 19 | Controlling sulfurization of 2D Mo_(2)C crystal for Mo_(2)C/MoS_(2)-based memristor and artificial synapse显示文摘Owing to the conductance-adjustable performance,the emerging two-terminal memristors are promising candidates for artificial synapses and brain-spired neuromorphic computing.Although memristors based on molybdenum disulfide(MoS_(2))have displayed outstanding performance,such as thermal stability and high energy efficiency,reports on memristors based on MoS_(2) as the functional layer to simulate synaptic behavior are limited.Herein,a homologous Mo_(2)C/MoS_(2)-based memristor is prepared by partially sulfuring two-dimensional Mo_(2)C crystal.The memristor shows good stability,excellent retention(~104 s)and endurance(>100 cycles),and a high ON/OFF ratio(>10^(3)).Moreover,for comprehensively mimicking biological synapses,the essential synaptic functions of the device are systematically analyzed,including paired-pulse facilitation(PPF),short-term plasticity(STP),long-term plasticity(LTP),long-term depression(LTD),and the transitions from STP to LTP.Notably,this artificial synapse could keep a highlevel stable memory for a long time(60 s)after repeated stimulation.These results prove that our device is highly desirable for biological synapses,which show great potential for application in future high-density storage and neuromorphic computing systems. | Xin Tang Leilei Yang Junhua Huang Wenjun Chen Baohua Li Shaodian Yang Rongliang Yang Zhiping Zeng Zikang Tang Xuchun Gui | 2022 | npj Flexible Electronics2022，6，1： | 0 |
