Abstract Biomass-derived porous carbon displays a great potential for lithium–selenium (Li–Se) batteries owing to its green resource and inherent structural advantages, which can effectively restrict the shuttle effect of Se cathode. Peanut meal, by-product of the extraction of peanut oil, is a promising precursor for N-doped porous carbon. However, peanut meal is difficult to be activated in solution due to its high hydrophobicity. Thus, non-reports have been available for peanut meal-derived porous carbon used as Li–Se battery cathode host. In this work, we have innovatively proposed a very simple method of activating peanut meal by directly physically grinding the activator with the peanut meal and then annealing it to convert it into nitrogen-doped three-dimensional porous carbon (N-PC) with rich nanoscale pore size structures, which is then used as the Se host for Li–Se batteries. The N-PC shows a high specific surface area of 938.872 m 2 g −1 . The Se/N-PC composite cathode delivers a specific capacity of 461.4 mA h g −1 for 250 cycles at 0.2 C, corresponding to a high-capacity retention of 97.2%. Moreover, the Se/N-PC composite maintains a high capacity over 340.1 mA h g −1 after 1,000 cycles at a high current density of 2 C. Our work effectively resolves the hydrophobic biomass activation problem and manufactures abundant and low-cost Se host for Li–Se batteries.
生物质衍生多孔碳由于其绿色资源和固有的结构优势，在锂硒电池中显示出巨大的潜力，可以有效地限制Se阴极的穿梭效应。花生油萃取副产物花生粕是一种很有前途的氮掺杂多孔碳前驱体。然而，由于花生粉的高疏水性，在溶液中很难被活化。因此，花生粕衍生多孔碳用作锂硒电池正极主体的研究尚无报道。在这项工作中，我们创新地提出了一种非常简单的激活花生粉的方法，即直接用花生粉物理研磨激活剂，然后退火将其转化为具有丰富纳米级孔径结构的氮掺杂三维多孔碳(N-PC)，然后将其用作Li-Se电池的Se主体。N-PC的比表面积高达938.872 m2 g−1。Se/N-PC复合阴极在0.2℃下循环250次，比容量为461.4 mA h g−1，相当于97.2%的高容量保留率。此外，在2℃的高电流密度下，Se/N-PC复合材料在1000次循环后仍保持超过340.1 mA h g−1的高容量，有效地解决了疏水生物质活化问题，为Li-Se电池制造了丰富且低成本的Se宿主。

Abstract The repair and remodeling of injured tissues, known as wound healing, is a multifaceted process. The use of nanotechnology to speed up the healing process of wounds by promoting the right kind of mobility through different mechanisms has shown a lot of promise. Several nanotechnologies with novel properties have emerged in recent years, each of which targets a different issue associated with wound-healing processes. Through their antibacterial, anti-inflammatory, and angiogenic actions, nanomaterials may alter the wound microenvironment from a non-healing to a healing state. Wound dressings including hydrogels, gelatin sponges, films, and bandages may all benefit from the use of nanoparticles (NPs) to keep harmful microbes out. The addition of bioactive substances like antibiotics, NPs, and growth factors to certain dressings may further boost their efficacy. In conclusion, this review sheds light on wound healing that may be aided by the special features of materials based on nanotechnology. Although nanomaterials for wound healing show great promise, further study is needed before this promising area can convert its findings into consumer-friendly solutions.

Abstract Date palm fiber (DPF) is an easily processed, low cost, and accessible natural fiber. It has mostly been used in composites for non-structural applications. For DPF to be utilized in cementitious composites for structural applications, ways to reduce its harmful effect on compressive strength must be devised. Therefore, in this study, nano-activated carbon (NAC), due to its filler effects, was used as an additive to produce the DPF-reinforced concrete (DPFRC). To produce the DPFRC, 0, 1, 2, and 3% by cement weight of DPF and NAC were added. The fresh properties, strength, and microstructure of the concrete were examined. The findings revealed that DPF decreased the consistency, density, and compressive strength. Additionally, it increases the porosity in the concrete microstructure. The addition of up to 1% NAC significantly improved the compressive, flexural, and split tensile strengths of the concrete, while it decreased the harmful impact of up to 2% DPF on the DPFRC’s strength. The split tensile and flexural strengths of the concrete were enhanced with the addition of up to 2% DPF without any NAC. The addition of up to 2% NAC densified the DPFRC’s microstructure by refining and filling the pores generated by the DPF. The multivariable statistical models developed to estimate the mechanical properties of the DPFRC containing DPF and NAC were very significant with a very high degree of precision.

Abstract Antifouling technologies have attracted considerable attention in recent years, as numerous fouling phenomena pertaining to inorganic, organic, bio-, and composite foulants substantially affect daily life. Poly(dimethyl siloxane) (PDMS) has several practical applications; however, it possesses limited resistance to inorganic, organic, or biofoulants such as proteins or bacteria. Among the antifouling strategies reported thus far, antifouling induced by surface wettability (AFISW) is an exceptional strategy with considerable potential. It presents numerous advantages such as a physical working mechanism, eco-friendliness, and facile material fabrication process. To achieve AFISW, PDMS can be modified with several nanomaterials to tune its surface wettability to meet antifouling requirements. This article presents a systematic review of the existing research on AFISW in PDMS to achieve improved antifouling performance. Specifically, we first provide a background on fouling, focusing on the different types of fouling and antifouling mechanisms. Then, we provide a comprehensive review of AFISW based on four types of surface wettability, namely, superhydrophilicity, hydrophilicity, hydrophobicity, and superhydrophobicity. Finally, we discuss suitable AFISW strategies for different types of fouling mechanisms based on PDMS and its nanocomposites. This review will help researchers design and fabricate various polymeric materials and their nanocomposites with tailored surface wettability for AFISW applications.

Abstract The smart membrane is a new type of functional membrane. The performance of this membrane is changed according to the variations in external physical and chemical signals. This membrane has become an essential focus in specific recognition, catalysis, selective permeation, and other fields. However, the problems of this membrane are weak anti-pollution ability, poor response performance, and inability of mass production. Therefore, scholars have done a lot of research on improving this membrane by modification, grafting polymerization, phase transformation, and in situ cross-linking copolymerization. This review provides a comparative investigation and summary of smart membranes, including temperature, light, electric field, magnetic field, pH, and specific molecular and ion-responsive membranes. Moreover, the authors also introduce the preparation process, selectivity, optimization and improvement of membranes, and their application fields. Finally, the authors’ perspective on the current key issues and directions of these fields for future development are also discussed.

Abstract CuW composite fabricated by powder metallurgy using ultrafine metal powders as raw materials has the disadvantages such as uneven microstructure and low compactness. A novel method of synthesizing an as-cast CuW composite ingot via an aluminothermic coupling with silicothermic reduction is presented; a low-melting-point CaO–Al2O3–SiO2 slag is formed by adding CaO as a slag former, effectively reducing Al2O3 inclusion in the CuW composite. In this study, the effects of CaO addition on the novel synthesis of the CuW composite via the aluminothermic coupling with silicothermic reduction are investigated. The result shows that CaO affects the removal of large particles (≥6 µm) but not the removal of small particles (≤4 µm). With the increase in the ratio of CaO ranging from 0 to 1.0, the inclusions in the CuW composites gradually transform from Al2O3 to calcium aluminates, which are conducive to the separation of the metal and slag. The contents of Si and O in the CuW composites gradually decrease from 9.40 and 14.00% to 6.10 and 3.50%, respectively, while those of Al and Ca gradually increase from 2.54 and 0.02% to 3.83 and 0.26%, respectively.

Abstract The treatment of infectious bone defects has become a troublesome issue in orthopedics. The disease requires effective anti-infective and bone-reconstruction therapeutic functionalities. In this study, we prepared a novel antibacterial material (vancomycin-impregnated periosteal extracellular matrix [Van-PEM]) by embedding vancomycin in a periosteal extracellular matrix (PEM)-derived hydrogel via physical stirring for the treatment of infectious bone defects. The microstructure, porosity, degradation, and release properties of this antibacterial hydrogel were characterized. The in vitro hemolytic reaction, cytotoxicity, osteogenic ability, and antibacterial properties were also carefully studied. The results showed that the Van-PEM hydrogel possessed a fibrous network structure with high porosity. Moreover, the hydrogel demonstrated slow degradation in vitro and could release vancomycin for at least 1 week. The hydrogel showed no cytotoxicity and possessed good biocompatibility with blood cells. It also promoted osteogenesis and exerted a significant bactericidal effect. Subsequently, the anti-infection and bone-healing abilities of the antibacterial hydrogel were investigated in a rat model of infectious calvarial defects, and the infectious skull defect was successfully cured in vivo. Therefore, Van-PEM hydrogels may represent a promising therapeutic approach for treating infectious bone defects.

Abstract “All in one” organic–inorganic nanocomposites with high biocompatibility and excellent physicochemical properties have recently attracted special attention in cancer imaging and therapy. Combination of organic and inorganic materials confers the nanocomposites with superior biocompatibility and biodegradability of organic materials, as well as magnetic, mechanical, and optical properties of inorganic materials. Increased endeavors have been made to produce diverse organic–inorganic nanocomposites and investigate their potential applications in cancer treatment.

Abstract Rechargeable aqueous zinc-ion batteries (AZIBs), a promising energy storage device in the large-scale energy storage market, have attracted extensive attention in recent years due to their high safety, low cost, environmental friendliness, and excellent electrochemical performance. Despite the rapid development of AZIBs technology, challenges such as insufficient energy density and limited cycling life still exist, which hinders the practical application of AZIBs. Due to the critical role that cathode materials play in the electrochemical performance of AZIBs, it is necessary to summarize the progress of cathode materials for AZIBs. In this review, the Zn 2+ storage mechanisms of the cathode materials are analyzed. Subsequently, the representative cathode materials are introduced, and their structures and electrochemical performances are compared. The existing problems and improvement strategies of these cathode materials are summarized in detail. Finally, the future challenges and promising prospects for cathode materials are proposed. This review will guide researchers and manufacturers, benefiting them in designing advanced AZIBs for grid-scale energy storage.

Subsequently, the representative cathode materials are introduced, and their structures and electrochemical performances are compared. The existing problems and improvement strategies of these cathode materials are summarized in detail. Finally, the future challenges and promising prospects for cathode materials are proposed. This review will guide researchers and manufacturers, benefiting them in designing advanced AZIBs for grid-scale energy storage.","PeriodicalId":18839,"journal":{"name":"Nanotechnology Reviews","volume":"367 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136207649","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
Abstract The bending of sandwich nanoplates made of functionally graded (FG) porous core and electromagnetic layers is explored for the first time through a nonlocal strain gradient theory and a four-unknown shear deformation theory. The proposed model can account for both nonlocal and strain gradient impacts. Therefore, the stiffness enhancement and stiffness reduction processes of sandwich nanoplates are observed. The porosities in the nanoplate are modeled with even and uneven distribution patterns. Six equations of equilibrium are constructed by using virtual work principle. The effects of the porosity factor, externally applied electric and magnetic fields, nonlocal parameter, strain gradient parameter, temperature and moisture parameters, aspect ratio, and side-to-thickness ratio on the static behaviors of FG sandwich nanoplates for simply supported boundary conditions are demonstrated using a parametric study. This article offers comparison treatments for the bending investigation of smart sandwich nanoplates, which can be used in a variety of computational methods. According to the results, deflections induced by negative electric and magnetic potentials behave differently than those brought on by positive electric and magnetic potentials. Other important findings are reached that should aid in the development and implementation of electromagnetic sandwich nanoplate structures.
