Superparamagnetic iron oxide nanoparticles (SPIONs) and core-shell type nanoparticles, consisting of SPIONs coated with mesoporous silica and/or lipid, were synthesised and tested for their potential theranostic applications in drug delivery, magnetic hyperthermia and as a contrast agent. Transmission Electron Microsc…
Fiber-shaped supercapacitors (FSCs), owing to their high-power density and feasibility to be integrated into woven clothes, have drawn tremendous attentions as a key device for flexible energy storage. However, how to store more energy while withstanding various types of mechanical deformation is still a challenge for…
Microsupercapacitors, as an energy storage device, have unique electrochemical performance, such as high power density, fast charging, long cycle life, and high safety. The reduction time and cost in fabrication processes of microsupercapacitors are important factors in microfabrication technology. In this work, a sim…
In the present work, ZnO:Dy3+ nanophosphors were synthesized by a simple, cost effective and eco-friendly route using the aqueous extract of Azadirachta Indica leaves. The prepared ZnO:Dy3+ nanophosphors were characterized using X-ray diffraction (XRD), Fourier Transformed Infra-Red (FTIR), Raman, UV-VIS diffuse refle…
Homogeneous dispersion of high-content graphene nano-platelet (GNP) in metals is challenging due to the serious aggregation tendency of graphene. Traditional secondary processing such as extrusion usually has too limited shear strains to reach a desirable GNP dispersion state. Our previous work demonstrated that 1.0 v…
The present work demonstrates the spinning of conductive filaments from oppositely charged nano-scale entities, i.e., cationic cellulose nanocrystals (CNC) and anionic graphene oxide (GO), via interfacial nanoparticle complexation. Especially, the role of CNC and GO concentration in filament formation was investigated…
Corn fiber, a by-product of the starch industry, is presently incorporated in animal feed. However, it has arabinoxylans as added-value components (besides ferulic acid) that should be valorized. In this work, the raw material, a fraction enriched in arabinoxylans from corn fiber, previously produced by alkaline extra…
High Resolution Image Download MS PowerPoint Slide Potentiodynamic polarization and electrochemical impedance measurements were employed to investigate the effect of acetic acid on the anodic dissolution of carbon steel in a CO 2 –H 2 S solution. Both polarization and impedance results unveil that the dissolution rate…
The search for elemental allotropes is an active research field to get unusual structures with unique properties. The removal of metal atoms from pressure-induced stable binary compounds has become a useful method for obtaining elemental allotropes with interesting properties that otherwise would not be accessible at…
High quality, epitaxial Ba(Zr0.35Ti0.65)O3 thin films were fabricated via radio frequency magnetron sputtering technique. The leakage current density vs electric field (J–E) tests were conducted using the device structures with Pt top electrodes and Nb-doped SrTiO3 bottom electrodes. The conduction mechanism of the fi…
In this study, a complex ring-opening agent including benzoic acid pentaerythritol ester bearing an aromatic group and pentaerythritol monolaurate bearing a pendant chain was applied in the ring-opening process. Bio-based polyols were obtained through epoxidation in the fixed-bed flow reactor and ring-opening reaction…
The effect of accelerated weathering on poly(lactic acid) (PLA) and a PLA nanocomposite with rutile titanium (IV) dioxide (rutile–TiO2) was investigated. The accelerated weathering test applied consecutive steps of ultraviolet (UV) (at 340 nm and 0.76 W m−2 irradiance) and moisture at 50 °C for 2000 h, following the A…
Lanthanide-doped upconversion nanoparticles (UCNPs) display highly beneficial photophysical features for background-free bioimaging and bioanalysis; however, they are instable in high ionic strength buffers, have no functional groups, and are nonspecifically interacting. Here, we have prepared NIR-excitable UCNPs that…
The direct patterning of colors using the bombardment of a focused beam of electrons onto a thin-film stack consisting of poly(methyl methacrylate) coated with a thin nickel film is demonstrated. This direct electron-beam color printing approach creates variations in the height of a Fabry-Perot (FP) cavity, resulting…
Zinc oxide@carbon quantum dots (ZnO@CQDs) nanocomposite was prepared via a facile hydrothermal method. Characterization of the obtained samples was carried out by Scanning electron microscopy‐EDX(SEM–EDX), Transmission electron microscopy (TEM), X‐ray diffraction (XRD), Photoluminescence (PL), and Fourier transformed…
Abstract Reducing greenhouse gas and pollutant emissions is one of the most stringent priorities of our society to minimize their dramatic effects on health and environment. Natural gas (NG) engines, in particular at lean conditions, emit less CO 2 in comparison to combustion engines operated with liquid fuels but NG…
Resonant optical antennas provide unprecedented opportunities to control light on length scales far below the diffraction limit. Recent studies have demonstrated that nanostructures made of multilayer transition metal dichalcogenides (TMDCs) can exhibit well-defined and intense Mie resonances in the visible to the nea…
Nitrogen–sulfur codoped carbon dots (NSCD) were synthesized via a single-step microwave-assisted method having a fluorescence quantum yield of ∼12%. The NSCD has been proven to be nontoxic and utilized as a fluorescent imaging nanoprobe for cancer cells (HeLa cells) under UV and blue light excitation ( in vitro enviro…
A novel strategy for preparing universal antifogging and antimicrobial coating is reported by the means of one-step coating and Ag nanoparticle (AgNP) formation in situ.
