Preparation and characterization of positively surface charged zinc oxide nanoparticles against bacterial pathogens

Solvothermal synthesis was used to investigate the formation of zinc oxide (ZnO) nanoparticles (NPs). A series of ZnO NPs was synthesized with different relative ratios of didodecyldimethylammonium bromide (DDAB) and zinc nitrate (ZN). The variation in the molarity influenced the crystallinity, size, and morphology of the obtained ZnO NPs. X-ray diffraction, Fourier-transform infrared spectroscopy, field-emission scanning electron microscopy, high-resolution transmission electron microscopy, and zeta potential analysis were used to study the characteristic features of the ZnO NPs. The ZnO surface charge, size, and morphological structure were highly reliant on the concentrations of DDAB and ZN. With increasing relative ratio of DDAB to ZN, the particle size of ZnO NPs decreased and the surface charge increased to higher positive value. The ZnO NPs synthesized with cationic liquid DDAB presented enhanced performance in preventing the growth of Staphylococcus aureus (S. aureus) and Escherichia coli (E. coli) strains. The antibacterial activity of ZnO NPs have direct contact with the microbial cell wall resulting in destruction of bacterial cell integrity, release of antimicrobial Zn2+ ions, and induce cell death. This is due to the positively charged smaller ZnO NPs, prepared with DDAB cationic surfactant, effectively acting as an antimicrobial agent against food-borne pathogenic bacteria.

High-temperature induced iodide and bromide ions filling lattice for high efficient all-inorganic perovskite solar cells

All inorganic CsPbX3 perovskites have gained great attentions owing to their excellent carrier transport property and thermal stability. However, the presence of X vacancy in the CsPbX3 lattice results in a high trap density within CsPbX3 films, and subsequently affects the photovoltaic performance of solar cells. Here, we use phenylethylammonium iodide (PEAL) and phenylethylammonium bromide (PEABr) to manipulate the film quality of inorganic perovskites, which significantly improve the moisture-resistance of the CsPbI2 Br film and photovoltaic performance. It is found that there is no so-called two-dimensional PEA(2)PbI(4) and PEA(2)PbBr(4) materials formed after a high temperature annealing, but iodine or bromide vacancies can be filled by external anions. The improved film quality with a low trap density renders the enhancement of the perovskite phase stability and the device efficiency of the CsPbI2Br solar cells. This work shows that filling vacancies by external anions can promote perovskite photovoltaic performance and stability. (C) 2020 Published by Elsevier B.V.

Correlating in vitro performance with physico-chemical characteristics of nanofibrous scaffolds for skin tissue engineering using supervised machine learning algorithms

The engineering of polymeric scaffolds for tissue regeneration has known a phenomenal growth during the past decades as materials scientists seek to understand cell biology and cell-material behaviour. Statistical methods are being applied to physico-chemical properties of polymeric scaffolds for tissue engineering (TE) to guide through the complexity of experimental conditions. We have attempted using experimental in vitro data and physico-chemical data of electrospun polymeric scaffolds, tested for skin TE, to model scaffold performance using machine learning (ML) approach. Fibre diameter, pore diameter, water contact angle and Young’s modulus were used to find a correlation with 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay of L929 fibroblasts cells on the scaffolds after 7 days. Six supervised learning algorithms were trained on the data using Seaborn/Scikit-learn Python libraries. After hyperparameter tuning, random forest regression yielded the highest accuracy of 62.74%. The predictive model was also correlated with in vivo data. This is a first preliminary study on ML methods for the prediction of cell-material interactions on nanofibrous scaffolds.

Self-Limited Grafting of Sub-Monolayers via Diels-Alder Reaction on Glassy Carbon Electrodes: An Electrochemical Insight

The grafting of molecular monolayers is critical for the functionalization of surfaces. In molecular electrochemistry, the surface modification of electrodes and the way molecules are attached to the electrode surface are highly critical to electron transfers and electrochemical reactions. In this paper, sub-monolayers were covalently grafted onto glassy carbon (GC) electrodes via Diels-Alder cycloaddition with two soluble dienophiles, that is, propargyl bromide and ethynyl ferrocene. Such an approach is clean (no by-product, no catalyst/additive) and occurs under mild conditions by heating at 50 degrees C in toluene for few hours. The as-modified electrodes were thoroughly characterized by FTIR, XPS, and cyclic voltammetry using both millimetric GC electrodes and ultra-microelectrodes. Cyclic voltammetry gave access to surface coverage and clearly evidenced the covalent grafting of sub-monolayers. The grafting of functional sub-monolayers via Diels- Alder cycloaddition could be easily extended to various functionalities and carbons to prepare electrochemical sensors or electrocatalytic surfaces.

Atmospheric degradation mechanism of Z/E-CF3CF = CHCl, CF3CF = CCl2, and CF2 = CFCl initiated by OH radicals using a smog chamber with long-path FT-IR at 298 K

The products and mechanism for the OH-initiated reaction with the Cl-containing fluoroolefins Z/E-CF3CF = CHCl, CF3CF = CCl2, and CF2 = CFCl were investigated, using a smog chamber linked to a Fourier-transform infrared spectrometer. That Cl atoms were generated from Cl-containing fluoroolefin reactions with OH radicals was proven, and significant acceleration was observed during the experiments. The corresponding Cl-initiated reaction products were identified as CF3CFClC(O)H for Z/E-CF3CF =CHCl, CF3CFClC(O)Cl for CF3CF=CCl2, and CF2CIC(O)F for CF2 = CFCl. The influence of Cl-release on the kinetic study using the relative method was also discussed. Mechanisms for smog chamber reactions between Cl-containing fluoroolefins and OH radicals and Cl atoms, and their atmospheric degradation mechanisms, were proposed, based on the identification and quantification of detected products. Secondary atmospheric impacts from these products were also discussed.

Hot water extract of Glehnia littoralis leaf showed skin-whitening and anti-wrinkle properties

Ethnopharmacological relevance: Glehnia littoralis (Umbelliferae) is a commonly used traditional medicine to treat the immune-related diseases in Korea, China, and Japan. Aim of the study: This study was designed to investigate the elastase and tyrosinase inhibitory potentials of hot water extracts of G. littoralis leaves. Materials and methods: An MTT (3-(4,5-dimethylthiazol-2-yl)-2,5 diphenyltetrazolium bromide) assay was conducted to measure the cytotoxicity of the extract on the HS68 and B16F10 cell lines. An ultraviolet (UV) irradiation protection effect on HS68 cells of the extract was also examined. The elastase and tyrosinase inhibition assays were conducted to determine anti-wrinkle and skin-whitening potentials of the plant extract. Results: The hot water extracts of G. littoralis leaves were nontoxic to two cell lines, HS68 and B16F10. Less than 10% cell death of the two cell lines and remarkable effect of the leaf extracts on UV irradiation protection of HS68 cells indicated noncytotoxic properties of G. littoralis leaves. The leaf extracts were found to have considerable tyrosinase and elastase inhibition potential, demonstrating skin whitening and anti-wrinkle properties, relative to ascorbic (250 mu g/mL) and ursolic (250 mu g/mL) acids. Conclusions: Findings of this study revealed that G. littoralis leaves could be used in the preparation of cosmetic products for skin whitening and anti-wrinkle applications. (C) 2019 SAAB.

Miscibility behavior of hydroxyethyl cellulose/poly(vinyl pyrrolidone) blends in the presence of some imidazolium based ionic liquids

In this study, the effect of 1-butyl-3-methyl imidazolium bromide ([BMIm]Br); 1-hexyl-3-methyl imidazolium bromide ([HMIm]Br) and 1-octyl-3-methyl imidazolium bromide ([OMIm]Br) ionic liquids on the miscibility of poly(vinyl pyrrolidone) and hydoxyethyl cellulose (PVP/HEC) blends were examined. The polymer solvent method was used to study miscibility of PVP/HEC blends. Two miscibility criterions on the based Delta[eta] and Delta K were used to evaluate miscibility. Both Delta[eta] and Delta K miscibility criterions confirmed that the PVP/HEC blends are miscible. PVP/HEC blends in the solid state were characterized with attenuated total reflective-Fourier transform infrared (ATR-FTIR) spectroscopy, differential scanning calorimetry (DSC) and field emission-scanning electron microscopy (FE-SEM). The miscibility of PVP/HEC blends was confirmed by ATR-FfIR, DSC and FE-SEM results. This miscibility was attributed to the strong intermolecular hydrogen bonding interactions between the -OH groups of HEC and -C = 0 groups of PVP. (C) 2019 Elsevier B.V. All rights reserved.

Non-CTAB synthesized gold nanorods-based immunochromatographic assay for dual color and on-site detection of aflatoxins and zearalenones in maize

New developing gold nanorods (AuNRs) are promising alternatives of gold nanospheres in the immunochromatographic assay (ICA) for the rapid screening of mycotoxins in cereals because of their unique threedimensional structure. Nevertheless, cetyltrimethylammonium bromide (CTAB) was used to prepare of AuNRs without exception in previous reports, resulting in poor biocompatibility, cytotoxicology and difficulty for further functionalization. In this study, we used non-CTAB synthesized AuNRs with different colors as labels on ICA for the screening of four aflatoxins and total zearalenones. The results showed the non-CTAB synthesized AuNRs was more stable and easier for further functionalization than CTAB-based AuNRs. The visual detection limits of developed AuNR-ICA were 0.5 ng/mL for AFB1 and 1 ng/mL for ZEN, and the quantitative detection limits were 0.05 ng/mL for AFB1 and 0.27 ng/mL for ZEN, respectively. The assay could accomplish qualitative detection and quantitative analysis within 20 min. The results of the AuNR-ICA were comparable to those of HPLC-MS/MS for naturally contaminated maize samples, indicating the feasibility of the AuNR-ICA in practical use. Given these performances, the non-CTAB synthesized AuNRs showed great potential for use as an effective label in the ICA development.
