This research discusses MCSF in a non-uniform channel by applying the Levenberg–Marquardt procedure via an artificial backpropagated neural network (LMP-ABNN). For two-dimensional and two-directional flows, mathematical formulations of double-diffusivity convection of a magneto couple stress fluid in nanofluids are developed. The partial differential equations are reduced to ordinary differential equations by using appropriate transformations. The assessment of the Hartmann number, thermophoresis parameter, Dufour parameter, Soret parameter, and magnetic Reynolds number over concentration profiles and temperature profiles is made by generating a dataset for LMP-ABNN based on the ND solve method for different variations of MSCFM. To examine the approximate solution validation, training and testing procedures are interpreted, and the performance is verified through error histogram and mean square error results. The extremely nonlinear equations are reduced by employing a long-wavelength approximation and a low but finite Reynolds number. To describe the behavior of flow quantities, graphical representations of a variety of physical characteristics of importance are shown. The impact of the Hartmann number and magnetic Reynolds number over axial magnetic field and current density is also studied. The concentration increases as the thermophoresis parameter and Dufour parameter values increase. This occurs because the concentration and both these parameters have a direct relationship. We observed opposite behavior for both the magnetic Reynolds number and the Hartman number. The behavior of current density J z increases with increasing values of R m. Both the temperature distribution and solute concentration increase. The final outcome of this study is to provide the potential for these techniques to provide new insights and solutions to challenging problems in nanofluids and other areas of fluid mechanics and to facilitate the design of more efficient and effective microfluidic devices.","PeriodicalId":18839,"journal":{"name":"Nanotechnology Reviews","volume":" ","pages":""},"PeriodicalIF":7.4,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43062010","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}

The purpose of this study was to investigate the effect of TiO 2 nanotubes (TNTs) and self-assembled minTBP-1-IGF-1 on implant osseointegration in type 2 diabetes mellitus (T2DM) rats. There were four groups, the control group, the TNTs group, the minTBP-1-IGF-1 group, and the minTBP-1-IGF-1-TNTs group. The atomic force microscopy and scanning electron microscope (SEM) results showed that 500 nm nanotubes were formed by anodic oxidation and minTBP-1-IGF-1 could self-assemble into almost all nanotubes. ELISA assay confirmed that more protein was adsorbed on TNTs surface. The contact angle of the minTBP-1-IGF-1-TNTs group was the lowest, confirmed that the hydrophilicity was the highest. The double fluorescence staining was used to evaluate the mineral apposition rate (MAR) at early stage and the MAR of the minTBP-1-IGF-1-TNTs group was the highest. Micro-CT images displayed that bone formed around the minTBP-1-IGF-1-TNTs implant was the most homogeneous and dense, and the quantitative analysis of these images at 12 weeks also confirmed these results. The cross-section SEM results showed that the connection between bone and minTBP-1-IGF-1-TNTs implant was the tightest. All results demonstrated that minTBP-1-IGF-1-TNTs can significantly improve low implant osseointegration under T2DM condition.","PeriodicalId":18839,"journal":{"name":"Nanotechnology Reviews","volume":"48 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":"135213956","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}

The aim of the current work was to elucidate the potential anticancer interactions between doxorubicin and GNPs loaded with tumor necrosis factor-alpha (TNF-α). To investigate whether GNPs loaded with TNF and doxorubicin could stimulate autophagy and apoptosis in breast cancer cells. Two human breast cancer cell lines, MCF-7 and AMJ-13, as well as different apoptotic and autophagy markers, were used. In both cell types, treatment with TNF-loaded GNPs in conjunction with doxorubicin increased the production of apoptotic proteins including Bad, caspase-3, caspase-7, and p53 with upregulation of the LC3-II and Beclin1 proteins. In addition, the findings showed that the mitogen-activated protein kinase signaling pathway was dramatically affected by the GNPs loaded with TNF-α and combined with doxorubicin. This had the effect of decreasing p-AKT while simultaneously increasing p-JNK1/2. The findings demonstrated that GNPs loaded with TNF-α and combined with doxorubicin can induce both autophagy and apoptosis in breast cancer cells. These results suggest that TNF- and doxorubicin-loaded GNPs provide a therapeutic option as a nanomedicine to inhibit the proliferation of breast cancer.","PeriodicalId":18839,"journal":{"name":"Nanotechnology Reviews","volume":"22 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":"134890479","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}

In this work, the mechanical properties of nano-SiO 2 -reinforced geopolymer composites (NSGPC) incorporated with varying dosages of polyvinyl alcohol (PVA) fibers were investigated under a complex environment. A simulated environmental chamber was employed to simulate the complex environment with relative humidity, temperature, and NaCl solution concentration of 100%, 45°C, and 5%, respectively. Fly ash/metakaolin geopolymer composites (GPCs) were fabricated by utilizing 1.5% nano-SiO 2 by weight and five various dosages of PVA fibers by volume (0, 0.2, 0.4, 0.6, and 0.8%). The compressive strength, tensile strength, elastic modulus, and impact resistance of NSGPC eroded in a simulated environmental chamber for 60 days were determined. Then, the impact of the PVA fiber dosage on the mechanical properties of NSGPC under complex coupled environments was analyzed. In addition, scanning electron microscopy (SEM) was employed to evaluate and analyze the microstructural behavior of NSGPC under complex environments. Results indicated that the compressive strength, tensile strength, elastic modulus, and impact resistance of NSGPC increased with increasing PVA fiber to 0.6% and then decreased with a continuous increase to 0.8% but remained higher than those of the reference specimen. NSGPC exhibited the best performance at a PVA fiber dosage of 0.6%, which increased by 13.3, 12.0, 17.2, and 522%, respectively. The outcomes of SEM analysis indicated that the usage of PVA fiber and NS remarkably improved the mechanical properties and microstructural behavior of GPC by making the inner structure of GPCs more robust and compact under a complex environment. The outcomes of this work can provide theoretical guidance for buildings serving under a complex environment.","PeriodicalId":18839,"journal":{"name":"Nanotechnology Reviews","volume":"14 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":"134981357","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}

NS has been used for asphalt modification, and improvement in high-temperature performance and several other physical properties has been reported. However, due to the wide varieties and intrinsic variability of asphalt materials, concerns have been raised about the reproducibility of some conclusions, and therefore, a review was conducted. According to the results, NS additives with a purity of over 99% were usually used for modification and the specific surface area was over 100 m 2 /g, leading to the superior absorption of asphalt and thus improvement in rutting resistance of the mixtures. Due to a lack of guidance for the blending procedures, inconsistency exists among studies in the shear speed, blending duration, and temperature, leading to possible excessive blending and unnecessary energy and time consumption. Rises in NS concentration would cause higher softening point and rotational viscosity, and therefore elevated temperatures for mixing and paving, but penetration would be reduced. According to rheological evaluations, with the rise of NS concentration, the rutting parameter would increase, indicating an improvement in the high-temperature performance, but the low-temperature performance may deteriorate.","PeriodicalId":18839,"journal":{"name":"Nanotechnology Reviews","volume":"364 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":"135446388","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}

More and more researchers utilized dECM derived from cells, tissues, and organs to fabricate tissue-engineered scaffolds to repair musculoskeletal tissues, since the bioactive molecules of dECM, such as fibrous proteins, proteoglycans, and adhesive glycoproteins, could provide various bioactive cues for tissue regeneration and remodeling. The physiochemical properties of dECM can be enhanced by changing decellularization and modification techniques. In addition, dECM can act as carriers of drugs, factors, or exosomes, delivering agents to injured tissues and promoting tissue repair and regeneration.

However, wood and bamboo have intrinsic faults like durability, ductility, physical and mechanical strength, and stability, limiting their applications in the industry. On the other hand, nanotechnology is a popular technology having numerous applications in different fields, resulting in a significant increase in expectations among academics, investors, the government, and industries. In contrast, nanotechnology can protect wood and bamboo from extreme conditions (bacteria, climate, etc.) by improving physicochemical characteristics because of its unique features. Nowadays, the trend of merging nanotechnology and forest industries to overcome the limitations mentioned above and get economically sustainable materials for construction, furniture manufacturing, flexible sensors developments, energy storage, battery manufacturing, and many more is increasing. Presently, several reviews on wood and bamboo modification by nanoparticles and nanomaterials have already been published. But, at this time, this study is essential because it aims to provide a brief guide about the recently developed eco-friendly sustainable materials from wood and bamboo, their uses, and how they can affect people’s daily life and helps to point out the gap of the current knowledge. In addition, we briefly describe the conventional and modern modification methods, including the influence of nanomaterials on wood and bamboo structures. This article is outlined as follows: The first phase of the review deals with wood and bamboo modification methods.

However, poor electrochemical capabilities such as the initial voltage delay phenomenon and the large polarization have obstructed their applications. The electrochemical performance of CF x primarily depends on the feature of the carbon source and the corresponding fluorination technique. Herein, we developed a high energy density Li/CF x battery by employing helical carbon nanotubes (HCNTs) as the carbon source. In detail, the precise control of the fluorination temperature was designed at the range of 250–400°C to tune the F/C ratio of CF x . Furthermore, the high F/C ratio of fluorinated HCNTs (F-HCNTs) reaches about 1.43, which surpasses the highest theoretical value in fluorinated crystalline carbon materials. Due to the active rich fluorination sites provided by the periodical insertion of the carbon pentacyclic (C5) and heptacyclic (C7) rings, HCNTs exhibited a defect-rich feature and F-HCNTs have a nodular shape. These features favor to enhance the transport of lithium ions and allow more C–F bonds to react with lithium ions, leading to a high energy density of 2133.13 W h/kg. This novel material offers an alternative approach for lithium primary battery being great potential in actual applications.","PeriodicalId":18839,"journal":{"name":"Nanotechnology Reviews","volume":" ","pages":""},"PeriodicalIF":7.4,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47363700","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}

How to broaden the light absorption of TiO2 and accelerate the separation of photo-generated electrons and holes is the focus of the current research. Building heterojunction with narrow band gap semiconductor and TiO2 is one of the important measures to improve its photoelectric performance. We prepared BiVO4/TiO2 binary heterojunction by the simple hydrothermal method and analyzed the effect of BiVO4 precursor solution concentration on the microstructure and photoelectric performance of the heterojunction. BiVO4/TiO2 binary heterojunction can effectively improve the photoelectric performance of TiO2, and the transient current density reaches 85 μA/cm2. To further boost the photocurrent of BiVO4/TiO2, Bi2S3 was in situ grown on the heterojunction to form Bi2S3/BiVO4/TiO2 ternary heterojunction. The results show that the band gap of Bi2S3/BiVO4/TiO2 composites is significantly narrowed compared with that of TiO2. The light absorption has been expanded to the visible range, and the photogenerated current density is also greatly boosted (0.514 mA/cm2). This Bi2S3/BiVO4/TiO2 ternary heterojunction accelerates the separation of photo-carriers and improves the photoelectric performance of the device. The possible transport mechanism of photo-carriers in ternary heterojunction is analyzed.
