Optoelectronics Letters 2025年第1期21卷 28-34页

作者： ZHAO Shuai ZHOU Ran LUO Mingming LIU Jianfei LIU Xiongfei ZHOU Tao school of electronic Information Engineering Hebei University of Technology Tianjin Key Laboratory of electronic materials and Devices school of Civil Engineering and Transportation Hebei University of Technology Tianjin Jinhang institute of Technical physics

The fiber optic sensing technology provides data support in structural health monitoring of the macro facilities, including design, construction, and maintenance of bridges, tunnels, ports and other infrastructures. In this paper, a distributed vibration sensing system is proved to be responsive to a single touch over a 1.8-m-long equivalent fiber segment, covering a vibration frequency from 5 Hz to 25 kHz. The sensing fiber was arranged as an S type layout on the bridge to recognize the standing state, windblown disturbance, and walking vibration. Moreover, the knocking and climbing events are recognized fiber laying spinning lines and hanging on the fences, respectively. The demonstration shows an accurate positioning and sensitive vibration monitoring applied on the automated three-dimensional(3D) printed bridge, which is applicable to all kinds of 3D printed facilities as intelligent sensory neuro-networks.

Strategies for improving the lithium-storage performance of 2D nanomaterials

引用

National Science Review 2018年第3期5卷 389-416页

作者： Jun Mei Yuanwen Zhang Ting Liao Ziqi Sun Shi Xue Dou school of Chemistry Physics and Mechanical Engineering Queensland University of Technology institute of superconducting and electronic materials University of Wollongong

2D nanomaterials, including graphene, transition metal oxide(TMO) nanosheets, transition metal dichalcogenide(TMD) nanosheets, etc., have offered an appealing and unprecedented opportunity for the development of high-performance electrode materials for lithium-ion batteries(LIBs). Although significant progress has been made on 2D nanomaterials for LIB applications in the recent years, some major challenges still exist for the direct use of these sheet-like nanomaterials, such as their serious self-agglomerating tendency during electrode fabrication and low conductivity as well as the large volume changes over repeated charging–discharging cycles for most TMOs/TMDs, which have resulted in large irreversible capacity, low initial Coulombic efficiency and fast capacity fading. To address these issues,considerable progress has been made in the exploitation of 2D nanosheets for enhanced lithium storage. In this review, we intend to summarize the recent progress on the strategies for enhancing the lithium-storage performance of 2D nanomaterials, including hybridization with conductive materials, surface/edge functionalization and structural optimization. These strategies for manipulating the structures and properties of 2D nanomaterials are expected to meet the grand challenges for advanced nanomaterials in clean energy applications and thus provide access to exciting materials for achieving high-performance next-generation energy-storage devices.

Dirac spin-gapless semiconductors:promising platforms for massless and dissipationless spintronics and new(quantum) anomalous spin Hall effects

引用

National Science Review 2017年第2期4卷 252-257页

作者： Xiao-Lin Wang Spintronic and electronic materials Group Institute for Superconducting and Electronic MaterialsAustralian Institute for Innovative MaterialsUniversity of Wollongong

It is proposed that the new generation of spintronics should be ideally massless and dissipationless for the realization of ultra-fast and ultra-low-power spintronic devices. We demonstrate that the spin-gapless materials with linear energy dispersion are unique materials that can realize these massless and dissipationless states. Furthermore, we propose four new types of spin Hall efects that consist of spin accumulation of equal numbers of electrons and holes having the same or opposite spin polarization at the sample edge in Hall efect measurements, but with vanishing Hall voltage. hese new Hall efects can be classiied as(quantum) anomalous spin Hall efects. he physics for massless and dissipationless spintronics and the new spin Hall efects are presented for spin-gapless semiconductors with either linear or parabolic dispersion. New possible candidates for Dirac-type or parabolic-type spin-gapless semiconductors are proposed in ferromagnetic monolayers of simple oxides with either honeycomb or square latices.

引用

Journal of materials Science & Technology 2017年第3期33卷 281-284页

作者： Xi Lou Jun Shang Liang Wang Haifeng Feng Weichang Hao Tianmin Wang Yi Du Center of Material physics and Chemistry Beihang University College of physics and electronic Engineering Henan Normal University institute for superconducting and electronic materials (ISEM) University of Wollongong

Bismuth-based compounds have been regarded as an important class of visible-light photocatalysts due to their special electronic structures. In this paper, iodide ions are introduced to modify bismuth-based compound, Bi（24）O（31）Br（10）, forming a Bi（24）O（31）Br（10）/BiOI heterojunction structure. A significant enhancement of photocatalytic activity compared to the parent compounds is observed in de-coloration of rhodamine B（Rh.B） solution. The improved photocatalytic property of Bi（24）O（31）Br（10）/BiOI heterojunction is ascribed to the unique electronic structure consisting of complementary band structures of BiOI and Bi（24）O（31）Br（10）.Iodide ions are regarded as an effective reagent to construct bismuth-based photocatalytic heterojunctions with improved photocatalytic activity.

作者： Jianhong Liu Qiang Zhou Yuxiao Lin Xinsheng Zhao Guangmin Zhou Xiaoxiao Li school of physics and electronic Engineering Jiangsu Normal University Tsinghua-Berkeley Shenzhen institute & Tsinghua Shenzhen International Graduate school Tsinghua University

An ever-increasing market demand has stimulated the soaring enthusiasm of researchers to develop wide-temperature supercapacitors(SCs). The active electrode is one of the most important parts of SC, which is directly related to the energy density,power transmission and long-term cyclability of the device in the wide-temperature environment. Compared with the SC electrodes aimed for room-temperature application, the SC electrodes for operating at wide-temperature scene often face greater challenges. In this review, the main challenges of SC electrodes under various temperature conditions, including low, high and cross-fade temperatures, are summarized. The relevant performance decay and failure mechanisms of wide-temperature SC electrodes are analyzed. In addition, this review deals with the recent studies and developments in robust wide-temperature SC electrodes with respect to the rational design of electrode structures and the exploitation of advanced active materials. Finally, the future directions for exploring reliable wide-temperature SCs are also proposed.

Sodium-ion batteries have received remarkable attention as next-generation high-performance electrochemical energy storage devices because of their cost effectiveness and the broad geographical distribution of sodium. As a critical component of sodium-ion batteries, anode materials, especially nanostructured anodes, have a significant effect on the electrochemical performance of sodium-ion batteries. Recent research indicates that phosphorus and metal phosphides show great promise as anode candidates for sodium-ion batteries because of their low cost and relatively high theoretical gravimetric and volumetric specific capacities. In this review, we systematically summarize recent research progress on state-of-the-art nanostructured phosphorus and phosphides, including the synthetic strategies, Na-storage mechanisms, and the relationship between the nanostructure and electrochemical performance. Moreover, we present an overview of future challenges and opportunities based on current developments.
