This study reports the preparation of 3D hierarchical carbon nanotube (CNT) @MnO2 core-shell nanostructures under the assistance of polypyrrole (PPy). The as-prepared CNT@PPy@MnO2 core-shell structures show a perfect coating of MnO2 on each CNT and, more importantly, a robust bush-like pseudocapacitive shell to effect…
Synthesized silver nanowire/polystyrene nanocomposites showed superior electrical properties to commercial carbon nanotube/polystyrene nanocomposites at high filler loadings. This was ascribed to the higher metallic nature of silver nanowires.
Flexible and transparent BC/PU composites were prepared, which exhibit excellent transparency (up to 90%) in the visible region and great mechanical properties, with a tensile strength of up to 69 MPa and a Young's modulus of up to 6 GPa.
The determination of corrosion rate for Mg and Mg alloys by electrochemical methods is complicated by several factors, including the intense hydrogen evolution (HE) that accompanies Mg dissolution, so hydrogen gas collection is often used. In the present paper a new gravimetric method for hydrogen gas collection, orig…
Lithium carbonate and lithium oxalate were incorporated as leachable corrosion inhibitors in model organic coatings for the protection of AA2024-T3. The coated samples were artificially damaged with a scribe. It was found that the lithium-salts are able to leach from the organic coating and form a protective layer in…
In the current paper, the physical properties and microelectronic parameters of direct current (DC) sputtered p-type CuO film and diode have been investigated. The film of CuO as oxide and p-type semiconductor is grown onto glass and n-Si substrates by reactive DC sputtering at 250 °C. After deposition, a post-anneali…
Monochrome LEDs and color graphical patterns were fabricated by changing the thickness and doping concentration of carbon dot layers.
Fluorescent magnetic nanoparticles with dual thermoresponsive and pH-sensitive polymeric nanolayers as anti-cancer drug carriers.
Contact-angle hysteresis of a liquid suspended on surface microstructures, namely in a Cassie-Baxter state, is determined mainly by the receding contact line although not fully understood. Existing modified Cassie-Baxter models predict some but not most experimental data in the literature. Noting that most models were…
The chemical reduction of graphene oxide (GO) typically involves highly toxic reducing agents that are harmful to human health and environment. Moreover, complicated surface modification is often needed to avoid aggregation of the reduced GO during reduction process. In this paper, GO was synthesized by modified Humme…
The resultant ternary spherical Ag–Cu <sub>2</sub> O/rGO composite with complex heterostructures exhibited excellent photocatalytic activity and higher stability.
An organic-ligand-free cuprous iodide trinuclear cluster with significant temperature-dependent structural distortion has been synthesized and characterized, which shows thermochromic luminescence originating from a single cluster-centered triplet due to the absence of an organic ligand. This compound also shows inter…
A silver incorporated graphene oxide nanocomposite was prepared and used for the detection of biomolecules using an absorbance based optical sensing method.
Nanoflake-structured NiO were synthesized by a microwave assisted method without the use of additives. The cubic phase of NiO nanoparticles with increasing crystalline nature for higher microwave power is ascertained by X-ray diffraction studies. Previous reports revealed that hexagonally structured β-Ni(OH)2 was comp…
The n-doped poly(phenanthrenequinone) is electrically conductive to be successfully used as the binder for nano-silicon negative electrodes.
One-pot hydrothermal synthesis of a NiS/rGO nanocomposite with NiS nanoparticles uniformly distributed on the three-dimensional porous conductive rGO nanoscaffold as high performance electrode materials for supercapacitors.
Quantification of adsorbed amounts requires in most cases several assumptions. Adsorption of organic compounds, for example, is usually measured indirectly, by mass balance calculations based on the evaluation of the remaining chemical in solution. Such procedure might yield overestimates when precipitation or degrada…
New NCDs were obtained and exhibit highly sensitive response to Pb <sup>2+</sup> which could be applied to real sample detection.
A supramolecular hydrogel was prepared through the host–guest interaction between β-cyclodextrin (β-CD) and ferrocene (Fc) with two polymers as pendant groups. Reversible gel–sol transition was observed with the alternative stimuli of a positive potential (or an oxidant) and a negative potential (or a reductant). The…
Supercapacitors with porous electrodes of graphene macroscopic assembly are supposed to have high energy storage capacity. However, a great number of "close pores" in porous graphene electrodes are invalid because electrolyte ions cannot infiltrate. A quick method to prepare porous graphene electrodes with reduced "cl…
