Hydrogen plays a crucial role in the chemical vapor deposition (CVD) growth of graphene. Here, we have revealed the roles of hydrogen in the two-step CVD growth of MoS2. Our study demonstrates that hydrogen acts as the following: (i) an inhibitor of the thermal-induced etching effect in the continuous film growth proc…
Engineered gold nanoparticles (AuNPs) have recently drawn an increased interest in disease diagnostics and therapies. However, reports on detailed studies of AuNPs regarding their pharmacodynamics, pharmacokinetics, biodistribution, metabolism and potential toxicity are limited. It is common knowledge that the in vivo…
A self-standing, vertically aligned carbon nanotube forest grown on unidirectional carbon fibers has been fabricated by using chemical vapour deposition.
We report the structural evolution of Pd-Zn alloys in a 3.6% Pd-12% Zn/Al2O3 catalyst which is selective for propane dehydrogenation. High signal-to-noise, in situ synchrotron X-ray diffraction (XRD) was used quantitatively, in addition to in situ diffuse-reflectance infrared Fourier transform spectroscopy (DRIFTS) an…
A novel electrochemical synthesis for graphene quantum dots (GQD) on a large scale from graphite oxide (GO) in pure water has been proposed.
Schematic illustration of the synthesis of sodium dodecyl sulfate (SDS) added to cobalt ferrite (CoFe <sub>2</sub> O <sub>4</sub> ) magnetic nanoparticles at various concentrations (0.04 and 0.08 M) and their morphological and magnetic characterizations.
An efficient edge-functionalization strategy with high specificity was employed to study the effects of conjugated structures on photoluminescence (PL) properties of graphene quantum dots (GQDs). Both the experimental results and density functional theory (DFT)-based calculations suggested the mechanism for conjugated…
Targeted delivery of copper oxide nanoparticles for breast cancer therapy.
Mesenchymal stem cells (MSCs) are among the most promising and suitable stem cell types for vascular tissue engineering. Substantial effort has been made to differentiate MSCs towards vascular cell phenotypes, including endothelial cells and smooth muscle cells (SMCs). The microenvironment of vascular cells not only c…
3D hierarchically porous transition metal oxides, particularly those involving different metal ions of mixed valence states and constructed from interconnected nano-building blocks directly grown on conductive current collectors, are promising electrode candidates for energy storage devices such as Li-ion batteries an…
Once nanoparticles enter a biological system, it is known that their surface is instantly covered by the biomolecules present with preference to proteins. This protein corona has been a subject of numerous studies in order to reveal its composition. Besides that, growing interest exists in its quantitative determinati…
Colloidal gels are formed during arrested phase separation. Sub-micron, mutually attractive particles aggregate to form a system spanning network with high interfacial area, far from equilibrium. Models for microstructural evolution during colloidal gelation have often struggled to match experimental results with long…
BODIPY (boron dipyrromethene) derivatives and Ru(ii) complexes are two types of functional compounds that have found wide applications in the fields of biology and medicine. We herein synthesized two new Ru(ii) arene complexes based on an iodized BODIPY-containing pyridine (py-I-BODIPY) ligand, [(p-cym)Ru(bpy)(py-I-BO…
Carrier concentrations dominated the TE properties in CuAgSe-based materials, which is a promising thermoelectric material near room temperature.
Silane coupling agent modified Ni <sub>0.4</sub> Zn <sub>0.4</sub> Co <sub>0.2</sub> Fe <sub>2</sub> O <sub>4</sub> ferrite decorated reduced graphene oxide nanocomposites were firstly synthesized, and their extraordinary microwave adsorption properties were investigated.
The result showed that the addition of 10 wt% Co <sub>2</sub> NiO to the MgH <sub>2</sub> exhibits a lower onset desorption temperature. The dehydrogenation and rehydrogenation kinetics of MgH <sub>2</sub> + 10 wt% Co <sub>2</sub> NiO were also improved compared to un-doped MgH <sub>2</sub> .
This paper describes a simple and versatile method for growing anisotropic plate shaped CuO nanostructures by simple, low temperature, and cost effective hydrothermal method. Scanning electron microscopy illustrated that the CuO nanostructures had an average particle size of 27nm. Structural analysis revealed that the…
A new electrode material for supercapacitor application is introduced based on polypyrrole conductive polymer and nickel-cobalt hexacyanoferrate poly-nuclear inorganic compound.
The reaction of Co(NCS)2 with 4-(4-chlorobenzyl)pyridine (ClBP) leads to the formation of Co(NCS)2(4-(4-chlorobenzyl)pyridine)4 () and [Co(NCS)2(4-(4-chlorobenzyl)pyridine)2]n (). In the crystal structure of the Co(ii) cations are octahedrally coordinated by two terminal bonded thiocyanato anions and four ClBP ligands…
