Alternative methods, including green synthetic approaches for the preparation of various types nanoparticles are important to maintain sustainable development. Extracellular or intracellular extracts fungi perfect candidates synthesis metal due scalability and cost efficiency fungal growth even on industrial scale. There several methods techniques that use fungi-originated fractions gold nanoparticles. However, there is less knowledge about drawbacks limitations these techniques....
The biomedical applications of silver nanoparticles (AgNPs) are heavily investigated due to their cytotoxic and antimicrobial properties. However, the scientific literature is lacking in data on aggregation behavior nanoparticles, especially regarding its impact biological activity. Therefore, assess potential AgNPs therapeutic applications, two different AgNP samples were compared under biorelevant conditions.Citrate-capped nanosilver was produced by classical chemical reduction...
Liposomal formulations, as versatile nanocarrier systems suitable for targeted delivery, have a highly focused role in the therapy development of unmet clinical needs and diagnostic imaging techniques. Formulating nanomedicine with zeta potential is an essential but challenging task. Formulations minimum ±30 mV are considered stable. The charge phospholipid bilayer can be adjusted membrane additives. present Quality by Design-derived study aimed to optimise liposomal formulations prepared...
Silver nanoparticles (AgNPs) are one of the most commonly investigated nanomaterials, especially due to their biomedical applications. However, excellent cytotoxic and antimicrobial activity is often compromised in biological media nanoparticle aggregation. In this work, aggregation behavior related three different samples citrate capped silver nanoparticles, with mean diameters 10, 20, 50 nm, respectively, were examined.Following synthesis characterization transmission electron microscopy,...
Fossil fuel depletion, global warming, climate change, and steep hikes in the price of are driving scientists to investigate commercial environmentally friendly energy carriers like hydrogen. Steam methane reforming (SMR), a current route for H2 production, has been considered best remedy fulfill requirements. Despite remarkable quantity produced by SMR, this technology still faces major challenges such as catalyst deactivation due sintering metal nanoparticles, coking, generation large CO2....
A galvanic replacement reaction has been successfully applied to prepare CuPd and CuPt bimetallic nanotubes. The nanotubes were characterized by transmission electron microscopy (TEM), scanning (SEM) combined with energy dispersive X-ray spectroscopy (EDS), diffraction (XRD) techniques. Ultralong, single crystalline copper nanowires (NWs) a diameter of ∼64 nm length several micrometers used as template material. By controlling the amount noble metal salt added, different compositions...
We discuss the formation mechanism of titania nanotubes synthesized by hydrothermal method. On basis a comprehensive analysis TEM, HRTEM, FT-Raman, and N2 adsorption data, we point out some major shortcomings currently accepted trititanate sheet rollup mechanism. suggest that novel mechanism, oriented nanotube crystal growth from nanoloop seeds, can explain experimental findings better than ones proposed so far.
Titanate nanowires were synthesized through the hydrothermal synthesis route (10 M NaOH, 130 °C) from anatase in a rotating autoclave. A combined TEM, SEM, XRD, FT−Raman, and N2 adsorption investigation of reaction products as function time revealed that 60−150 nm wide ∼5 μm long are fact formed by merging self-assembled nanotube bundles. The able to further self-assemble into longer than 30 long, dense "superbundles" if is allowed run enough. We propose spontaneous arrangement could be...
Copper nanowires (NWs) with uniform diameters and lengths ranging from several hundreds of nanometers to micrometers have been prepared high yield by a simple hydrothermal procedure. The X-ray diffraction (XRD) energy dispersive spectroscopy (EDS) analysis data indicate that the copper are free any contamination, while electron (ED) has revealed be single crystals. nanowire growth mechanism also discussed. Hexadecylamine is surface stabilizing agent in our method, glucose facilitates...
The effect of the nature support and promotion achieved by a Rh additive on Co-based catalysts in ethanol steam reforming reaction were studied. with 2% Co loading characterized temperature-programmed reduction (TPR) X-ray photoelectron spectroscopy (XPS). In situ diffuse reflectance Fourier-transform infrared (DRIFTS) identified surface intermediates formed during reaction, whereas gas phase products detected chromatography (GC). Upon heating hydrogen to 773 K, cobalt could not be reduced...
Due to obvious disadvantages of the classical chemical methods, green synthesis metallic nanoparticles has attracted tremendous attention in recent years. Numerous environmentally benign methods have been developed yielding via low-cost, eco-friendly, and simple approaches. In this study, our aim was determine suitability coffee tea extracts silver as well compare performance obtained materials different biological systems. We successfully produced (C-AgNP GT-AgNP) using extracts; moreover,...
We report the synthesis of N-doped TiO(2) nanofibers and high photocatalytic efficiency in generating hydrogen from ethanol-water mixtures under UV-A UV-B irradiation. Titanate synthesized by hydrothermal method are annealed air and/or ammonia to achieve anatase fibers. Depending on route, either interstitial N atoms or new N-Ti bonds appear lattice, resulting slight lattice expansion as shown XPS HR-TEM analysis, respectively. These were then used support for Pd Pt nanoparticles deposited...
A thermoplastic polyurethane (TPU) composite film containing hexadecyl-functionalized low-defect graphene nanoribbons (HD-GNRs) was produced by solution casting. The HD-GNRs were well distributed within the matrix, leading to phase separation of TPU. Nitrogen gas effective diffusivity TPU decreased 3 orders magnitude with only 0.5 wt % HD-GNRs. incorporation also improved mechanical properties films, as predicted and indicated tensile tests dynamic analyses. could lead potential applications...
