ABSTRACT A lot of attention is being paid to developing new electrode materials for energy storage with good stability and excellent specific capacitance. This work involves hydrothermal and oxidation processes to grow NiCo2@PEDOT/PMo12 materials on carbon cloth. At 20 mA cm−2, the prepared electrodes show an extremely high capacitance of 3476 mF cm−2. The results prove that NiCo2, PEDOT, and PMo12 ternary components synergized to promote electron transport and electrolyte diffusion. The SC device presents a high energy density of 0.41 mW h cm−3 at a power density of 8.57 mW cm−3, and cycle stability test shows 108.1 % after 600 cycles and 74.5 % after 6000 cycles. In addition, the capacitance of the ASC device is smaller than that of the SC, but the device retains 101.4 % of its initial capacitanc after 10000 cycles at 2 mA cm−2 .

ABSTRACT In the present article, we have developed an eco-friendly, phytosynthetic, cost-effective, and straightforward method for the synthesis of ZnO nanoparticles using leaf extracts of Juglans Regia (JR) as green reducing agents. The powder X-ray diffraction pattern revealed the high crystalline nature of synthesised ZnO nanoparticles also rivalled with ICSD no. 98–009-4004. The SEM images of the samples showed the spherical and irregularly distributed rod and plate-like structures. The EDS spectrum filed only Zn and O peaks revealed that the sample has good purity in ZnO nanoparticles. The HRTEM analysis explained the formed ZnO nanoparticles by biogenic reduction were hexagonal shape with definite edges and the average grain size was obtained as 33.18 ± 6.2 nm for the 50JR sample. The d-spacings of fringes and SAED pattern got also rivalled with XRD d-spacings. According to the UV-Visible analysis, the values of peak absorbance wavelength decreased (blue shift) with the increase in the leaf extract concentrations. The bandgap values were calculated in the range of 2.74–3.17 eV. The Fourier Transform Infra-Red study explicated the biomolecules for the reduction of nanoparticles and also ZnO bonding. These results also proved the presence of ZnO nanoparticles synthesised using Juglans Regia extract. Regarding the antimicrobial effects of ZnO NPs, ZnO NP which was using 50 mL JR extracts was detected as highly efficient nanoparticles against test microorganisms. In particular, the highest antimicrobial activity was measured with 15.66 ± 1.15 mm against Candida albicans 10,231 and revealed data compared with fluconazole, as reference antifungal, recorded 69% antimicrobial index. The findings demonstrated that ZnO NPs can be evaluated for use in biomedical applications. Graphical Abstract

ABSTRACT A non-enzymatic glucose sensing nanocomposite comprised of CoFe2O4 nanosheets grown on Reduced Graphene Oxide (CoFe2O4@rGO) has been triumphantly prepared by a facile co-precipitation process. The characterisation results reveal that the CoFe2O4 nanosheets are vertically grown on the rGO substrate and form a porous network structure. Next, Electrochemical workstation is applied to study the glucose detection performance of the CoFe2O4@rGO. The sensing tests exhibit that when the volume ratio of anhydrous ethanol and deionised water is 10 ml: 30 ml, the fabricated CoFe2O4@rGO has better glucose detection performance. Its linear detection ranges from 0.5 mM – 10 mM and 10 mM – 35 mM, and the sensitivity reaches 50.5 μAmM−1cm−2 and 143.6 μAmM−1cm−2 respectively, which is significantly better than the previously reported non-enzyme glucose sensing materials. Furthermore, the CoFe2O4@rGO has good anti-interference and stability.

ABSTRACT The carbon nanotubes attached mesoporous Ag3O4-coated NiO nanosheets were prepared successfully through hydrothermal method. The structural, morphological and electrochemical properties of the prepared nanocomposite have been studied. The X-ray diffraction and Raman analysis confirms the presence of NiO, Ag3O4 and carbon nanotubes in the prepared sample. HRTEM images clearly show the coating of Ag3O4 on the NiO and attachment of carbon nanotubes. BET surface area analysis confirms the mesoporous nature of the prepared composite. The cyclic voltammetric (CV), galvanostatic charge-discharge (GCD) and impedance analysis were made to explore the electrochemical nature of the composite. Cyclic voltammograms reveals the maximum specific capacity of 415.86 mAh g−1 at the scan rate of 3 mV s−1 and GCD analysis exhibits the specific capacity of 416.63 mAh g−1 at 1 A g−1. The prepared nanocomposite retained 97% of maximum capacity even after 1500 cycles.

ABSTRACT We investigated the anti-cancer properties of gold nanoparticles loaded TNF- and CALNN peptides, which we proposed as a potential drug delivery system using in vitro and in vivo models. The binding of GNPs-TNF- and GNPs-TNF-CALNN was characterized using a UV, ELISA and SEM analysis. The outcomes demonstrated that a novel drug delivery system had an anti-proliferative activity against breast cancer cell lines through a mechanism of apoptosis induction. In vivo model involved studying the cytotoxic influence of a drug delivery system GNPs, GNPs-TNF-α and GNPs-TNF-α-CALNN when applied to the transplanted AN-3 cell line. tumor sections were examined using microarray. In-vivo studies demonstrated that GNPs alone had less of a growth inhibitory effect on tumors implanted in mice when compared to GNPs-TNF – CALNN combined therapy. The cytotoxic assay showed that GNPs, GNPs-TNF-α and GNPs-TNF-α-CALNN exhibit selective toxicity towards cancer cells, inducing cell apoptosis through activation of caspase-3 and 7, p53 protein.

ABSTRACT There are many traditional agents whose combination with new technologies can offer effective therapeutic impacts. Accordingly, the purpose of this study was to evaluate the effects of PLGA nanoparticles (NPs) loaded with anbarnesa smoke organic extract (P-ASOE) against A2780 ovarian cancer cell line. Thus, nanoparticles were synthesised using W1/O/W2 method and characterised by FESEM, DLS and FTIR techniques. Cytotoxicity of P-ASOE on A2780 and healthy (HFF) cells was assessed using MTT assay. Acridine Orange/Propidium Iodide (AO/PI) staining, flow cytometry and expression profiles of P53, TNFα, CAS-3 and CAS-9 genes were recruited to evaluate the effect of P-ASOE on apoptosis of A2780 cells. The antiangiogenic effect of P-ASOE was studied through chorioallantoic membrane (CAM) assay as well as evaluation of VEGF and VEGFR gene expression. The histological effects of P-ASOE on healthy and cancerous tissues of mouse models were investigated. The results showed that the synthesised NPs had dose- and time-dependent cytotoxic effects on A2780 cells but not on HFF cells. In addition, all assays indicated pro-apoptotic effects of P-ASOE, which significantly reduced number and length of blood vessels as well as length and weight of chick embryos. The expression levels of VEGF and VEGFR genes were also significantly decreased under the influence of NPs. According to in vivo examinations, P-ASOE treatment reduced tumour size while having no significant histological effect on healthy tissues. All findings were in favour of the anti-cancer potential of P-ASOE against A2780 cancer cell line.

ABSTRACT Surface modification can effectively improve the biological activity of Ti, which is currently a popular research topic. In this study, we applied plasma electrolytic oxidation (PEO) technology to prepare a porous Mg-TiO2 coating on the surface of a Ti sheet. Then, we observed the adhesion and proliferation of bone marrow mesenchymal stem cells (BMSCs) on the surface of the Mg-TiO2 coating. The results showed that the Mg-TiO2 coating had a porous structure, and there was a uniform distribution of Mg on the surface and in the pores of the coating. The porous Mg-TiO2 coating showed good cytocompatibility and no obvious cytotoxicity. Significantly more BMSCs adhered to and proliferated on its surface than on pure Ti (p < 0.05).

In this study, we applied plasma electrolytic oxidation (PEO) technology to prepare a porous Mg-TiO2 coating on the surface of a Ti sheet. Then, we observed the adhesion and proliferation of bone marrow mesenchymal stem cells (BMSCs) on the surface of the Mg-TiO2 coating. The results showed that the Mg-TiO2 coating had a porous structure, and there was a uniform distribution of Mg on the surface and in the pores of the coating. The porous Mg-TiO2 coating showed good cytocompatibility and no obvious cytotoxicity. Significantly more BMSCs adhered to and proliferated on its surface than on pure Ti (p < 0.05). In conclusion, a Mg-TiO2 coating with a good surface morphology and good biocompatibility and bioactivity was prepared on a Ti surface by plasma technology and may have potential for clinical applications.","PeriodicalId":18270,"journal":{"name":"Materials Technology","volume":"86 1","pages":"3129 - 3139"},"PeriodicalIF":3.1,"publicationDate":"2022-09-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84368736","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}

ABSTRACT In order to endow carbon fibre (CF) bioactivity, an in-situ-grown carbon nanotube-Fe3O4-dicalcium phosphate dehydrate (IC-FE-D) composite coating has been prepared on CF by a combination method of chemical vapour deposition, slurry method and electrochemical deposition. The morphology, microstructure and in-vitro bioactivity of the IC-FE-D composite coating are analysed. Results show that the ICNTs form a porous structure on CF. Fe3O4 particles are distributed on surface of ICNTs and in the gaps between ICNTs. The introduction of Fe3O4 particles could favour the nucleation of the following dicalcium phosphate dehydrate. The flake dicalcium phosphate dehydrate shows a good interaction with ICNTs and Fe3O4 particles. The IC-FE-D composite coating exhibits good biomineralisation in simulated body fluid. The IC-FE-D composite coating prepared on CF integrating both mechanical properties and biocompatibility may be an ideal candidate material for bone tissue engineering.

ABSTRACT Laser-induced periodic surface structures (LIPSS) on biomedical stainless steel in air and water were systematically studied. The LIPSS exhibit in-plane curves near the ripple centres in the individual tracks of laser scan and the curving was opposite to the laser scan direction. The collective in-plane curving of LIPSS, a hitherto unknown feature for single train pulsed laser processing, is attributed to the accumulative effect of laser ablation and redeposition, which modifies the interference between the surface scattered wave and the incident laser beam. Combinations of media, scan-speed, and laser fluence, showed that the roughness can be increased by slowing the scan-speed. Ripples fabricated in the flowing water with slow scan-speed and high laser power are helpful for the hydrophilicity of biomaterials. A contact angle as low as 47.00 ± 9.35° is obtained towards high surface hydrophilicity. The results provide new insights on LIPSS about their formation and biomedical applications.
