Zinc phosphate nanoparticles (ZnPNPs), an inorganic material, possess some unique features, such as high thermal stability, low solubility in corrosive media, biocompatibility, non-toxicity and luminescence property. As a result, ZnPNPs have enormously been explored by researchers in many important applications, such as anticorrosion pigment, drug delivery, antibacterial as well as anticancer agents, biocatalyst, lubricant additives, regeneration of bone tissues and removal of toxic metal from the environmental samples, and so on. Considering diversified applications potential, morphologically different ZnPNPs have mainly been fabricated by precipitation, sonochemical and biological methods. The surface property of ZnPNPs differs with pH, temperature, reaction time, and substrate concentrations. One-step in situ and facile synthetic procedures, as well as greener synthesis protocols of ZnPNPs can be advantageous over conventional methods to eliminate toxic chemicals and by-products. In addition, both artificial and natural polymer-modified ZnPNPs would offer improved properties, such as better colloidal stability, option for further functionalization, and render desired biocompatibility of prepared hybrid nanocomposite particles in applying for targeted applications. Furthermore, both in vitro and in vivo studies of polymer functionalized ZnPNPs can be an attractive research topic in biotechnological and electrochemical fields. Therefore, the current review provides a summary of the recent progress on the fabrication methods, an opportunity for the future directions to the researchers in the improvement of shape-selective synthesis and application potentials of ZnPNPs.","PeriodicalId":16525,"journal":{"name":"Journal of Nano Research","volume":"1 1","pages":"59 - 88"},"PeriodicalIF":1.7,"publicationDate":"2022-05-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89674706","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The synthesized nanocatalysts were confirmed using different characterization techniques such as Energy Dispersive X-ray, Scanning Electron Microscope, X-ray diffraction analysis, Zeta Potential, Dynamic light Scattering, UV-Visible spectroscopy, and Fourier Transform Infrared Spectroscopy. To validate the competency of the nanocatalysts as the photocatalyst, the synthesized ZnO/PVP nanocatalysts were applied to the degradation of methyl orange dye. Lastly, the fabricated catalyst demonstrated splendid catalytic efficiency; within 90 seconds, more than 98% degradation of methyl orange dye was perceived using 150 μg nanocatalysts dose in the aqueous medium. The fabricated ZnO/PVP nanocatalysts illustrate many benefits above traditional routes for degrading the toxic and hazardous dye, like a short time, high percentile of degradation, the least amount of nanocatalysts, and admirable reusability. On the above facts, it is recommended that these viable and effective nanocatalysts can be applied successfully on the commercial level for degradation hazard pollutants.","PeriodicalId":16525,"journal":{"name":"Journal of Nano Research","volume":"2015 1","pages":"121 - 138"},"PeriodicalIF":1.7,"publicationDate":"2022-05-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86995063","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Nanomaterials can provide the needed functionality to such labels. Application of ink compositions containing silver nanoparticles on paper materials by screen printing is quite promising. A special ink composition was developed based on Ag nanoparticles that possess changeable photoluminescence properties in contact with compounds that indicate food decay. The possibility of application of this ink onto the surface of paper-based materials via screen printing was studied. The influence of ink layer thickness, characteristics of paper materials (degree of sizing, content of optical brighteners), and content of the fluorescent component in the ink composition on photoluminescence properties of printed labels for smart packaging was investigated. It was determined how to choose proper values of these technological parameters in order to obtain high luminescence intensity and predetermined luminescence color of printed labels using the developed nanophotonic inks. The results of the study allow industrial production of functional labels for smart packaging with nanophotonic elements with the needed optical (photoluminescence) characteristics, as well as for protecting packaging from counterfeiting.","PeriodicalId":16525,"journal":{"name":"Journal of Nano Research","volume":"48 1","pages":"1 - 14"},"PeriodicalIF":1.7,"publicationDate":"2022-05-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89969713","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The mass ratios between the OAm:PVP were respectively set to the 1:2, 1:1, 2:1 values. Platinum acetylacetonate (Pt(acac)2) was used as Pt precursor and the reduction of this salt to the metallic Pt was provided by microwave irradiation technique. It is seen that increasing amount of OAm triggers the formation of cubic shape Pt NPs. The average sizes of the Pt NPs fall in the range of 6-8 nm. The unsupported Pt NPs were directly used as a catalyst for the oxygen reduction reaction (ORR). According to the hydrodynamic ORR voltammograms of the catalysts, the Pt NPs prepared with 1:2 (OAm:PVP) exhibit the highest current density at all stirring rates of rotating disc electrode (RDE). Besides, Pt NPs prepared with 2:1 (OAm:PVP) have the minimum charge transfer resistance based on electrochemical impedance spectroscopy (EIS) analysis conducted at 0.9 V. After all these analyses, Pt NPs were synthesized using extra five different ratios (1.5:1, 1:1.5, 2.5:1, 3:1, 1:3) of (OAm:PVP) for thoroughly examining the optimum value for the ORR catalytic activity. As a result, the Pt NPs prepared with a 2.5:1 (OAm:PVP) ratio provided the best performance among all the catalysts.","PeriodicalId":16525,"journal":{"name":"Journal of Nano Research","volume":"789 1","pages":"31 - 50"},"PeriodicalIF":1.7,"publicationDate":"2022-05-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76928006","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Based on the modified couple stress theory and surface elasticity theory, the size-dependent model is formulated for 2D-FG Euler-Bernoulli beam. The material properties of the beam smoothly change along both the axial and thickness directions according to power-law distribution. The continuous spatial variations of the single material length scale parameter and the three surface constants are incorporated to describe the effects of microstructure and surface energy, respectively. This model accounts for the axial and transverse displacements, the exact position of the physical neutral plane, and Poisson’s effect. To obtain the static response of the present model, Ritz method is employed by approximating the axial and transverse displacements in terms of polynomial forms. Different boundary conditions, i.e., Simply-simply (S-S), Clamped-clamped (C-C), Clamped-simply (C-S), and Clamped-free (C-F), are considered and satisfied by adding auxiliary functions to the displacement functions. Numerical results with various cases of boundary conditions are performed with an insight to explore the effects of gradient indices in thickness and length directions, surface energy, material length scale parameter, slenderness ratio, and thickness on the static deflection and buckling responses of 2D-FG nanobeams. Results disclose that, the material properties, the surface energy, and microstructure effects have a significant effect on the bending, and buckling responses of 2D-FG nanobeams. Hence, this study can be helpful in the design and optimization of 2D-FG nanobeams in bending and buckling responses.","PeriodicalId":16525,"journal":{"name":"Journal of Nano Research","volume":"33 1","pages":"89 - 120"},"PeriodicalIF":1.7,"publicationDate":"2022-05-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80919219","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Boron nitride nanosheets (BNNSs) were synthesized using the liquid exfoliation method. BNNSs/PVB multilayer thin film was coated on tubes by dip-coating. After the UV irradiation of coated and uncoated glass tubes at different times, the total phenol content (TPC) and antioxidant activity of olive oil (TAA) were determined. Specific absorption coefficients K232 and K270 in the ultraviolet region were measured for estimating the oxidation degree of olive oil after irradiation. Free fatty acid (FFA) in olive oil after UV irradiation was determined by the titration method. Olive oil quality analysis indicates that BNNSs/PVB coating on the glass is effective on the protection of TPC and TAA of olive oil. In addition, the results show that extra virgin olive oil in the coated glass tube is maintained nearly 2 times more than the amount of phenol in the uncoated tube. While olive oil samples in glass tube coated with 30 and 50 times exceeded the limit of K270 value (0.22) after 400 hrs, it was determined that olive oil samples in uncoated glass exceeded this limit after 215 hrs. After 720 hours of UV irradiation, the free fatty acid value of the UCOL (uncoated) sample increased by 24.7% compared to the initial value, while the increase in the COL50 (coated) sample was 15%.","PeriodicalId":16525,"journal":{"name":"Journal of Nano Research","volume":"50 1","pages":"37 - 51"},"PeriodicalIF":1.7,"publicationDate":"2022-03-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80760599","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
