1The Dabie Orogen as the early Jurassic sedimentary provenance: Constraints from the detrital zircon SHRIMP U-Pb dating显示文摘The SHRIMP U-Pb ages of detrital zircon from the oldest Mesozoic strata, the Fanghushan Fomation, in the Hefei Basin range from 200 Ma to ca. 2500 Ma, which indicates that the Dabie Orogen as the early Jurassic sedimentary provenance was complex. The composition of the Dabie Orogen includes: the Triassic high pressure-ultrahigh pressure metamorphic rocks, of which the detrital zircon ages are from 234 Ma to 200 Ma; the rocks possibly related to the Qinling and Erlangping Groups representing the southern margin of the Sino-Korean craton in the Qinling and Dabie area, of which the detrital zircon has an age of 481-378 Ma; the Neoproterozoic rocks originated from the Yangtze croton, of which the detrital zircon ages are 799-721 Ma old; and the rocks with the detrital zircon ages of ca. 2000 Ma and ca. 2500 Ma, which could be the old basement of the Yangtze craton.LI Renwei, WAN Yusheng, CHENG Zhenyu, ZHOU Jianxiong, XU Yunhua, LI Zhong & JIANG Maosheng Institute of Geology and Geophysics, Chinese Academy of Sciences, Beijing 100029, China Institute of Geology, Chinese Academy of Geological Sciences, Beijing 100037, China Institute of Mineral Resources, Chinese Academy of Geological Sciences, Beijing 100037, China 2005Science China Earth Sciences2005,48,2:9

7Continuous Preparation of Chitosan‑Based Self‑Powered Sensing Fibers Recycled from Wasted Materials for Smart Home Applications显示文摘Currently,the gradual depletion of fossil resources and the large amount of plastic waste are causing serious harm to the land and marine ecology.The rapid development of wearable smart fibers is accompanied by rapid growth in the material demand for fibers,and the development of green and high-performance biomass-based fibers has become an important research topic to reduce the dependence on synthetic fiber materials and the harm to the environment.Here,chitosan is first prepared from the waste material by chemical methods.Then the chitosan-based self-powered induction fibers are prepared by electrospinning core wire technique.Chitosan-based self-powered sensing fiber is ultra-light and flexible,which can achieve about 2500 collisions without damaging the surface.Chitosan-based self-powered sensing fiber can also be used in smart home sensing applications to control home appliance switches with a light touch,which has a great application prospect in smart home and wearable fields.Yingying Li Chuanhui Wei Yang Jiang Renwei Cheng Yihan Zhang Chuan Ning Kai Dong Zhong Lin Wang 2022Advanced Fiber Materials2022,4,6:1
8Underwater Monitoring Networks Based on Cable-Structured Triboelectric Nanogenerators显示文摘The importance ofocean exploration and underwater monitoring is becoming vital,due to the abundant biological,mineral energy,and other resources in the ocean.Here,a self-powered underwater cable-based triboelectric nanogenerator(TENG)is demonstrated for underwater monitoring of mechanical motion/triggering as wllas searching and rescuing inthe sea.Using a novel double-layer winding method combined with ferroelectric polarization,a self-powered cable-structured sensor with a stable electrical output has been manufactured,which can accurately respond to a variety of external mechanical stimuli.A self-powered cable sensing network woven using smart cables can comprehensively transmit information,such as the plane osition anddivedhofasumersbeMorereiely,can analyzeitsdrtionfmovemnt,seedand pathaong w transmiting information such as the submersible's size and momentum.The developed self-powered sensor based on the cable-based TENG not only has low cost and simple structure but also exhibits working accuracy and stability.Finally,the proposed work provides new ideas for future seabed exploration and ocean monitoring.Yihan Zhang Yingying Li Renwei Cheng Shen Shen Jia Yi Xiao Peng Chuan Ning Kai Dong Zhong Lin Wang 2022Research2022,,2:0
9Wearable energy harvesting-storage hybrid textiles as on-body self-charging power systems显示文摘The rapid development of wearable electronics requires its energy supply part to be flexible,wearable,integratable and sustainable.However,some of the energy supply units cannot meet these requirements at the same time,and there is also a capacity limitation of the energy storage units,and the development of sustainable wearable self-charging power supplies is crucial.Here,we report a wearable sustainable energy harvesting-storage hybrid self-charging power textile.The power textile consists of a coaxial fiber-shaped polylactic acid/reduced graphene oxide/polypyrrole(PLA-rGO-PPy)triboelectric nanogenerator(fiber-TENG)that can harvest low-frequency and irregular energy during human motion as a power generation unit,and a novel coaxial fiber-shaped supercapacitor(fiber-SC)prepared by functionalized loading of a wet-spinning graphene oxide fiber as an energy storage unit.The fiber-TENG is flexible,knittable,wearable and adaptable for integration with various portable electronics.The coaxial fiber-SC has high volumetric energy density and good cycling stability.The fiber-TENG and fiber-SC are flexible yarn structures for wearable continuous human movement energy harvesting and storage as on-body self-charging power systems,with light-weight,ease of preparation,great portability and wide applicability.The integrated power textile can provide an efficient route for sustainable working of wearable electronics.Feifan Sheng Bo Zhang Renwei Cheng Chuanhui Wei Shen Shen Chuan Ning Jun Yang Yunbing Wang Zhong Lin Wang Kai Dong 2023Nano Research Energy2023,2,4:0
10Unusual uranium biomineralization induced by green algae: Behavior investigation and mechanism probe显示文摘As a biosorbent,algae are frequently used for the biotreatment or bioremediation of water contaminated by heavymetal or radionuclides.However,it is unclear that whether or not the biomineralization of these metal or radionuclides can be induced by algae in the process of bioremediation and what the mechanism is.In this work,Ankistrodsemus sp.has been used to treat the uranium-contaminated water,and more than 98%of uranium in the solution can be removed by the alga,when the initial uranium concentration ranges from 10 to 80 mg/L.Especially,an unusual phenomenon of algae-induced uranium biomineralization has been found in the process of uranium bioremediation and its mineralization mechanism has been explored bymultiple approaches.It is worth noticing that the biomineralization of uranium induced by Ankistrodsemus sp.is significantly affected by contact time and pH.Uranium is captured rapidly on the cell surface via complexation with the carboxylate radical,amino and amide groups of themicroalgae cells,which provides nucleation sites for the precipitation of insolubleminerals.Uranium stimulates Ankistrodsemus sp.to metabolize potassium ions(K+),which may endow algae with the ability to biomineralize uranium into the rose-like compreignacite(K_(2)[(UO_(2))6O_(4)(OH)_(6)]•8H_(2)O).As the time increased,the amorphous gradually converted into compreignacite crystals and a large number of crystals would expand over both inside and outside the cells.To the best of our knowledge,this is the first investigated microalgae with a time-dependent uranium biomineralization ability and superior tolerance to uranium.This work validates that Ankistrodsemus sp.is a promising alga for the treatment of uranium-contaminated wastewater.Yanxia Cheng Ting Zhang Shunzhang Chen Feize Li Renwei Qing Tu Lan Yuanyou Yang Jiali Liao Ning Liu 2023Journal of Environmental Sciences2023,,2:0
11Scalable one-step wet-spinning of triboelectric fibers for large-area power and sensing textiles显示文摘Textile-based electronic devices have attracted increasing interest in recent years due to their wearability,breathability,comfort.Among them,textile-based triboelectric nanogenerators(T-TENGs)exhibit remarkable advantages in mechanical energy harvesting and self-powered sensing.However,there are still some key challenges to the development and application of triboelectric fibers(the basic unit of T-TENG).Scalable production and large-scale integration are still significant factors hindering its application.At the same time,there are some difficulties to overcome in the manufacturing process,such as achieving good stretchability and a quick production,overcoming incompatibility between conductive and triboelectric materials.In this study,triboelectric fibers are produced continuously by one-step coaxial wet spinning.They are only 0.18 mm in diameter and consist of liquid metal(LM)core and polyurethane(PU)sheath.Due to the good mechanical properties between them,there is no interface incompatibility of the triboelectric fibers.In addition,triboelectric fibers can be made into large areas of T-TENG by means of digital embroidery and plain weave.The T-TENGs can be used for energy harvesting and self-powered sensing.When they are fixed on the forearm can monitor various strokes in badminton.This work provides a promising strategy for the large-scale fabrication and large-area integration of triboelectric fibers,promotes the development of wearable T-TENGs.Chuan Ning Chuanhui Wei Feifan Sheng Renwei Cheng Yingying Li Guoqiang Zheng Kai Dong Zhong Lin Wang 2023Nano Research2023,16,5:0
