Abstract In the last decade, nanostructuration is a demanding research topic due to the observation of interesting properties and, in consequence, applications on these nanostructures. This review collects the synthesis and possible applications of ZnO nanowires grown by electrodeposition and electroless methods. Respect to the synthesis of ZnO nanowires, growth mechanism and parameters are analysed depending on the technique used, electrodeposition or electroless. The mechanism growth of the nanowires using templateless and hard-templates is analysed resulting in different architecture of the ZnO nanowires. Moreover, ZnO nanowires and hybrid materials based on ZnO are also considered. Depending on the architecture of ZnO nanowires, the properties and applications are different. This review also studies the properties and applications in which ZnO nanowires can be used and how these applications are different depending on the architecture of the nanostructure. This review gives a complete perspective referent to the synthesis, properties and application of ZnO nanowires grown by electrosynthesis techniques.

Abstract MAX phase materials a new family of ternary layered carbide and nitride compounds are represented by the general formula of Mn+1AXn, where n = 1 ∼ 3, M stands for early transition metal, A express A-group elements, and X is either nitrogen or carbon. As early as 1960s, this materials had been paied much attention due to their unique physical properties combination of metals and ceramics such as machinability, low hardness, excellent electrical, good thermal conductivity, damage tolerance, thermal shock resistance, high elastic moduli, oxidation and corrosion resistance. Therefore, MAX phase ceramics can be used as structural and functional materials, and is regarded as an ideal strengthening phase for metal matrix composites. Researchers have recognized the potentially technologically important application of this emerging material in the fields of aerospace, high-speed rail, nuclear industry, gas igniter, heat exchanger, high thrust rocket nozzle, electric brush, kiln furniture, metal refining electrode and high-temperature seal. In recent years, a new research caused heightened concerns on MAX phase, as the feasibility of attaining MXenes via selectively etching these and removing of the A-group element. In this review, the development of MAX phase and th e characteristics and applications of its derivative of MXenes are introduced in the first place. Next, the structure, morphology, electronic structure and diversity of the MAX phase are described. Thirdly, the different preparation methods and related applications of MAX phase films, bulk materials and powder materials are systematically introduced according to the current preparation technologies. Finally, the future development potential of MAX phase and the related improvement of the research subject are prospected. It aims to provide theoretical guidance and new ideas for synthesizing and creating new and excellent MAX phase materials, so that this new type of material can be put into social production and application in large quantities.

Abstract We provide a survey of the results of recent experiments, molecular dynamics simulations and theoretical models concerning the plastic deformation and fracture processes in metal-matrix composites reinforced with graphene platelets or graphene nanoribbons. We consider homogeneous metal/graphene composites with randomly oriented and aligned graphene platelets, as well as laminated metal/graphene composites. The focus of the review will be on the strengthening and strain hardening mechanisms of the composites and the results of modeling the processes of their plastic deformation and strength properties. We examine in detail the effects of the inclusion dimensions, characteristics of interfaces, and the presence of buffer layers between the metal matrix and graphene on strength and ductility of metal/graphene composites. We critically review various theories of strengthening of such composites and discuss the contradictory results that these theories predict. In addition, various plastic deformation and fracture processes, including dislocation interaction with graphene inclusions, grain and lamella boundaries, self-healing of the composites, and crack generation and growth, will be examined, and the influence of these processes on the mechanical properties of metal/graphene composites will be discussed. We demonstrate that the excellent mechanical properties of metal/graphene composites are related to their unique microstructure and the variety of strengthening and strain hardening mechanisms. We also discuss the effect of the bimodal grain size distribution of the metallic matrix on their strength and ductility. The summary will outline the conclusions and briefly highlight unresolved issues and prospects for further research.

Abstract The selectivity of a sensor is the ability to discriminate the target from the interference molecules and display a target-specific sensor response. It is a critical trait for gas sensors that are used in real-time air pollution control, hazardous materials detection, food quality inspection and personal health monitoring. Attaining high target selectivity ensures that sensors will exhibit accurate information about the existence and concentration of a target gas, which is essential for reliable sensor response. To obtain target selectivity, it is critical to determine the optimum modification technique and receptor materials as well as to understand how each method works and how it could be designed for a specific target. For this purpose, in this review we present the working principles of the three leading chemical modification methods including catalyst decoration, composite formation, and surface functionalization, as well as the selection criteria of various recognition materials. Throughout the report, we offer a rich apprehension of these techniques by providing mechanistic insights, application areas, advantages, disadvantages, and plausible applications for the invention of the target-specific gas sensors.

Abstract There is an increasing demand of highly sensitive, stable and highly selective gas sensors to detect toxic gases. This is inspired by the need to monitor the concentration of these gases in order to guarantee humans, animals and environmental safety. Metal ferrites (AFe2O3, where A is a metal) based sensors are paramount in this field of sensing. Among the gases detectable using metal ferrites includes carbon monoxide (CO), liquefied petroleum gas (LPG), hydrogen sulfide (H2S), petrol and methane (CH4). This reviews presents various parameters which plays key role in the design of ferrite gas sensors. They include; operating temperatures, dopants, grain size, particle size, selectivity, surface area, concentration of the gas, sensitivity as well as recovery time. In addition, the various methods which are used to synthesize ferrite gas sensors are briefly explained. Key considerations in the designing of excellent ferrite gas sensors such as calcination temperature, working temperature, dopants, and concentration as well as optimization condition among others are outlined. In addition this paper reviews the various metal ferrites such as nickel ferrites and nickel doped ferrites, cobalt and cobalt doped ferrites, zinc and zinc doped ferrites, magnesium and magnesium doped ferrites among others that have been researched as gas sensors.

Abstract In recent years, heteroatoms-doped graphene, with its exceptional properties, has generated significant advances in many fields of modern nanoscience and nanotechnology. With the rapid progress in doped graphene research, advanced graphene materials have been developed and frequently used in electromagnetic shielding applications. In this context, heteroatom-doping of graphene materials has been considered as an efficient strategy for the development of novel electromagnetic interference (EMI) shielding materials. This article aims to provide a timely update on the synthesis and EMI shielding applications of doped graphene materials. Heteroatom-doped and co-doped graphene-based materials (n-type and p-type doping) have been synthesized using various chemical and physical routes. Extensive approaches and strategies have been applied for achieving the intended doping/co-doping levels in graphene-based materials. Doping in graphene and its derivatives induces the formation of defects, changing the electrical conductivity as well as the mechanical properties. This results in an increase of reflection, and an improvement of absorption, enhancing shielding effectiveness. This review article provides a comprehensive overview of doping strategies for graphene and related composites, their EMI shielding performance, as well as comments on the future perspectives and possible challenges for doped graphene-based materials. We hope this review article offers a valuable starting point for researchers entering the field, providing an overview of synthesis approaches and EMI shielding applications.

Abstract In order to reduce oil consumption and avoid fossil fuel-related environmental problems, scientists are always looking for lightweight structural materials that show high performance during both processing and application. Among various candidates, Mg seems to be the most promising. Mg is ∼33, 60, and 75% lighter than Al, Ti, and steel, respectively. However, the vast applications of Mg are impeded due to its intrinsic brittleness at room temperature, which is related to the hexagonal close-packed crystal structure of Mg. In this crystal structure, the limited number of independent slip systems available at room temperature leads to brittle behavior and low fracture toughness. Thus, engineers and scientists all over the world have shown a great deal of interest in fabricating Mg-based materials with improved ductility. In this review, accordingly, the origin of low ductility in pure Mg and the fundamentals of designing highly ductile Mg alloys will be presented and critically discussed. In addition, the recent advances achieved in the field of Mg alloys with high ductility via control of structure and composition will be outlined. Finally, various properties of highly ductile Mg-based materials, including creep, fatigue, corrosion, and formability, will be discussed. Graphical abstract

Abstract In view of the drawbacks of high-cost and inherent brittleness of indium tin oxide (ITO) based transparent electrodes, silver nanowires (AgNW) networks have been considered as promising alternatives owing to their excellent optical transparency, mechanical flexibility, and compatibility with large scale printing process. AgNWs have been applied as transparent electrodes in many electronic devices, however, in many cases, they inevitably interact with the surrounding media (e.g., temperature, electric field, UV light irradiation, etc.) which will cause performance degradation. For instance, AgNWs show a typical Rayleigh instability phenomenon when the external temperature is higher than a critical point. Moreover, a specific range of UV light or/and intensive current density can accelerate the partial breakage of AgNW networks. To develop highly stable AgNW based transparent electrodes for flexible electronic devices, intensive research works have been conducted to mitigate the degeneration issues. In this review, the degradation mechanisms of AgNW based transparent electrodes have been systematically studied. Furthermore, the mainstream strategies for mitigating the deterioration of AgNW based transparent electrodes have been analyzed. Finally, the present challenges in current materials processing, and future research directions have been discussed.

Abstract Carbonaceous material, especially carbon nanotubes (CNTs), have incredible properties, such as high thermal and mechanical stabilities, good catalytic and adsorption capabilities. In recent years, hybrid nanocomposites have attained considerable attention, due to the combination of unique organic and inorganic elements in a single material. Hence, these nanocomposites have been employed for various applications, such as drug delivery, sensors, corrosion protection materials, flame retardant additives, and pollutant adsorbent. These nanocomposites can be fabricated through various approaches that include powder metallurgy, solution processing, reaction processing, melt processing, electrochemical, and many more. This present review mainly summarizes the various techniques for the fabrication, separation, and purification of CNTs and their nanocomposites, especially CNTs-based polymer and CNTs-based metals/metal oxides nanocomposites. Besides, effects of CNTs embedded with polymers (such as polypyrrole, poly-aniline, and poly-thiophene, etc.) and metals/metal oxides (such as manganese oxide (MnO2), copper (Cu), gold (Au), platinum (Pt), etc.) and how they can be employed toward innovative devices with fascinating properties for a broad range of applications are thoroughly discussed. Further, , industrial applications of CNTs-based polymer/ metal/metal oxides nanocomposites have been reviewed and discussed.

This present review mainly summarizes the various techniques for the fabrication, separation, and purification of CNTs and their nanocomposites, especially CNTs-based polymer and CNTs-based metals/metal oxides nanocomposites. Besides, effects of CNTs embedded with polymers (such as polypyrrole, poly-aniline, and poly-thiophene, etc.) and metals/metal oxides (such as manganese oxide (MnO2), copper (Cu), gold (Au), platinum (Pt), etc.) and how they can be employed toward innovative devices with fascinating properties for a broad range of applications are thoroughly discussed. Further, , industrial applications of CNTs-based polymer/ metal/metal oxides nanocomposites have been reviewed and discussed.","PeriodicalId":55203,"journal":{"name":"Critical Reviews in Solid State and Materials Sciences","volume":"25 1","pages":"837 - 864"},"PeriodicalIF":10.8,"publicationDate":"2021-07-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77997181","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Abstract Invention of friction stir welding (FSW) is revolutionarily redefined solid-state materials joining process for lightweight constructions. With numerous commercial applications, FSW has been classified as a matured joining process with some key issues, such as high shoulder heat input on top surface, high process downforce, weld thinning, and relatively poor surface asperity. Stationary shoulder friction stir welding (SSFSW) is one of the most important variants derived from the conventional FSW (CFSW) possessing almost uniform and balanced heat input through the thickness of plates to be welded. Thus, the SSFSW eliminates or suppresses the above key issues of the CFSW process with improved microstructural and mechanical properties. Numerous reviews are available summarizing the development of CFSW, while not such on SSFSW. With the advancement of SSFSW in recent years, sufficient literature of SSFSW deserves a review to help researchers from both academia and industry gaining process aspects and unexplored areas. The present paper summarizes the research progress on SSFSW critically reviewing microstructural evolution, mechanical properties, and derivatives to cope with particular problems. Moreover, this review provides a detailed comparison of CFSW, SSFSW, and bobbin tool friction stir welding (BTFSW) on different aspects, such as process principle, tooling system, heat generation, joint features, and joint performance. To put more emphasize on commercialization of SSFSW, the different variants of SSFSW along with their industrial applications are also presented. Finally, the process challenges and future scopes of SSFSW are proposed.
