Unlike the conventional sintering processes, SPS takes advantage of a current flow passing through the sintering die and metallic powders by which fast densification with minimal grain growth and enhanced physicomechanical properties can be obtained. Albeit there is a growing interest in the exploitation of SPS in producing sufficiently consolidated metallic parts, no analytical review has been released over the effects of SPS parameters on the densification behavior, microstructure evolution, and resultant physicomechanical properties of metallic parts and their alloys. In the present review, recent developments and ongoing challenges in modeling the SPS of metallic systems are thoroughly explored. Then, the effects of main SPS parameters including sintering temperature, dwell time, heating rate, and pressure on the microstructure and physicomechanical properties of metals and alloys are comprehensively investigated. These properties are categorized into two groups: (i) physical properties including relative density, electrical and thermal conductivities; (ii) mechanical properties with a systematic focus on hardness, elastic modulus, and tensile, compressive, and bending strengths. In each section, the general trends along which SPS parameters grow to affect each corresponding property are comprehensively discussed. Additionally, various microstructural phenomena being more likely to occur at the given metallic systems are fully addressed. The present work seeks to elaborate on the aforementioned issues and provide an overview of the unresolved challenges and proposed solutions to them.","PeriodicalId":55203,"journal":{"name":"Critical Reviews in Solid State and Materials Sciences","volume":"18 1","pages":"169 - 214"},"PeriodicalIF":10.8,"publicationDate":"2022-03-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86070613","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}

This is of concern, as the surface condition can markedly deteriorate fatigue performance. Additionally, the adaptation of surface finishing methods for AM components with topologically optimized designs can be a costly practice. It is therefore desirable to consider deploying AM parts with no or minimal surface processing for targeted applications. This requires an in-depth understanding of the formation of various types of AM surfaces, including the variation in surface condition and controlling factors, and their influence on mechanical performance. The last few years have seen significant research advances in these aspects. Ti-6Al-4V is the most extensively studied alloy for AM. The research data available now allows an informative treatment of this topic for both practical applications and future research. Using laser powder bed fusion (LPBF) of Ti-6Al-4V as a model AM − alloy system, this article examines (i) the characteristics of various types of LPBF surfaces including horizontal, vertical, inclined, upward, downward, internal isolated, and slotted surfaces; (ii) the design features and LPBF variables that affect the surface topography; (iii) the capabilities of existing post-AM surface processing methods; and (iv) the influence of AM surface topography on mechanical properties by focusing on the fatigue performance. On this basis, design considerations are recommended for AM of consistent surfaces, and priority surface-related research issues are identified. The purpose is to establish an essential knowledge base for improved commercial designs for LPBF for suitable dynamically loaded applications, with no or minimal surface processing. While centering on LPBF of Ti-6Al-4V, the insights derived are expected to be applicable to other AM processes or metallic materials.","PeriodicalId":55203,"journal":{"name":"Critical Reviews in Solid State and Materials Sciences","volume":"44 1","pages":"132 - 168"},"PeriodicalIF":10.8,"publicationDate":"2022-03-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"72839303","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}

The alignment of LC molecules remains pivotal to explore the basic and applied aspects of LCs. Various alignment techniques such as rubbing of polyimides, coating of surfactants, magnetic field, oblique evaporation of SiOx, photoalignment, etc. have been widely explored to obtain the uniform alignment of LCs, eventually required in the fabrication of LC based displays and other photonic devices. One has to judiciously select the alignment technique to produce LC displays at industrial scale. However, certain issues have always remained which further stimulated the researchers to explore new sustainable ways of aligning LCs. Under this framework, the nanoparticles-controlled alignment could be one of new methods to align LCs. In this review, we have focused on the nanoparticles (isotropic and anisotropic) controlled alignment of LCs. The alignment of LCs could be achieved by: (i) doping of nanoparticles in the bulk LCs and (ii) patterning or growth of nanostructures on the substrates. Interestingly, the nanostructures grown on the non-conducting substrate are found to work as LC aligning agent and transparent conducting electrode. The nanoparticles doped polyimide alignment layers are also found to significantly improve the alignment of LCs. The quality of LC alignment obtained by using nanoparticles is more or less same as in conventional alignment techniques but less time consuming and cost-effective. Besides the induced or improved alignment of LCs due to nanoparticles, the electro-optical properties of LC devices are also found to be greatly improved as compared to devices using conventional alignment techniques. Moreover, we have discussed the pros and cons and future perspectives of nanoparticles tuned alignment of LCs.","PeriodicalId":55203,"journal":{"name":"Critical Reviews in Solid State and Materials Sciences","volume":"1 1","pages":"57 - 92"},"PeriodicalIF":10.8,"publicationDate":"2022-02-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81934869","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}

However, PSCs exhibit some drawbacks, such as poor stability upon exposure to moisture or humidity, ultraviolet (UV) radiation and heat, which in turn limits the device lifetime and performance. In addition, the introduction of perovskite films comes with associated toxicity, which is a major environmental concern. Furthermore, the application of titanium dioxide (TiO2) as an electron transport layer (ETL) and 2,2′,7,7′-tetrakis[N,N-di(4-methoxyphenyl)amino]-9,9′-spirobifluorene (spiro-OMeTAD) as a hole transport layer (HTL), causes device instability. The wide-bandgap characteristic of TiO2 introduces charge carrier recombination in the ETL, which, in turn, impairs device performance. This is, over and above, the high cost of spiro-OMeTAD, coupled with its multi-step synthetic preparation method. To address the aforementioned shortcomings, approaches, such as modifying the interfacial architecture, have been explored by introducing versatile materials between the charge-collecting electrode and the perovskite active layers. In this regard, perovskite oxides are more appealing due to their wide bandgap and high electron mobility. However, perovskite oxides have limitations due to their agglomeration, which causes short-circuits and leakage current, in addition to their poor charge separation efficiency, surface hydrophilicity and weak visible-light absorption. As a result, nanocomposites of perovskite oxides with carbon-based materials, particularly graphene and its derivatives, have attracted significant research attention due to their exceptional optoelectronic properties, superior stability, and non-toxicity of graphene-based materials. Therefore, this review discusses the recent trends in graphene-based materials, their composites with perovskite oxides, effective ETLs or HTLs of PSCs and the subsequent improvement of photovoltaic performance. In addition, a summary of synthetic routes for perovskite oxides/graphene nanocomposites is presented. This review will foster the advancement of the fabrication of PSCs with improved PCE and stability.","PeriodicalId":55203,"journal":{"name":"Critical Reviews in Solid State and Materials Sciences","volume":"16 1","pages":"112 - 131"},"PeriodicalIF":10.8,"publicationDate":"2022-02-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85889766","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}

Among these properties, electrochemical and thermal-induced degradation involving corrosion and high-temperature oxidation, respectively, are critical as they impact service life of the component. Advanced manufacturing techniques under additive manufacturing (AM) offer capabilities of fabricating complex structural and functional, near-net shaped engineering components. Owing to the excellent weldability, and ease of precursor (powder/wire) formability, Ti alloys are especially suitable for production using AM techniques. In contrast to narrow range of near-equilibrium thermokinetic conditions in conventionally processing techniques of these alloys, AM fabricated materials encompass vast range of regimes of near to fully non-equilibrium thermokinetic and thermomechanic factors including multiple, extremely rapid heating/cooling cycles, steep thermal gradient, and severe thermal stress cycles controlled via distinct precursor morphology, processing atmosphere, and process parameters. Consequently, AM components exhibit characteristic microstructures including but not limited to heterogenous grain structure, non-equilibrium phase evolution, and presence of 3D macro/micro defects like crack networks, porosity, and crystallographic and atomic defects. These characteristics have been suggested to impact electrochemical and thermal-induced degradation of Ti alloys. Hence, there exists AM process induced variation in results and differed views about the mechanisms underlying these variations. The considerable prospect of AM for optimized fabrication of corrosion-resistant Ti alloys remains partly unrealized and provides plenty of room to explore. In this review, we discuss the present scenario of corrosion and high-temperature oxidation in AM Ti alloys. The process-induced peculiarities associated with AM and influence of these peculiarities and ambient media have been highlighted. Further, efforts to mitigate the corrosion/oxidation of AM components via post processing are reviewed. The review concludes comprehensively on the AM process-induced variation in corrosion and high temperature oxidation of Ti alloys.","PeriodicalId":55203,"journal":{"name":"Critical Reviews in Solid State and Materials Sciences","volume":"21 1","pages":"915 - 954"},"PeriodicalIF":10.8,"publicationDate":"2021-10-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89010130","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}
