We report here the dielectric characteristics of a potential nanocomposite consisting of graphene doped with CuS nanoparticles and ZnO nanotubes for supercapacitance applications.
We found stable n-type doping and carrier mobility improvement of graphene by using KNO <sub>3</sub> solution and investigated photo-desorption current response.
A magnetically separable graphene–iron oxide nanotube composite was synthesised for the first time <italic>via</italic> an adept template free hydrothermal route.
Ce–Al <sub>2</sub> O <sub>3</sub> showed an excellent catalytic activity and reusability for the self-condensation of <italic>n</italic> -butyraldehyde to 2-ethylhexanol. The acid–base property of Ce–Al <sub>2</sub> O <sub>3</sub> other than Ce valence state played a dominant role in its catalytic performance.
The surface of oxidant crystals facilitates the simultaneous synthesis and morphogenesis of conductive polymer materials. Oxidant crystals as a condensed phase of the oxidative agent induce the formation of the conductive polymer nanoparticles and their accumulated films.
In this comparative study of dispersion profile-catalytic performance relationships, Pt (of 0.3, 0.6 and 0.9 wt%) was supported on mesoporous silica surface <italic>via</italic> microwave assisted solution method or rotary chemical evaporation method in the <italic>in situ</italic> reduction step.
The emission peaks of the obtained NaSr <sub>(3.98−x)</sub> Ba <italic>x</italic> (BO <sub>3</sub> ) <sub>3</sub> :0.02Eu <sup>2+</sup> phosphors can be continuously tuned from 609 nm to 544 nm by adjusting the Ba <sup>2+</sup> concentration.
Biodegradable polymers with pendent pair-wised carboxylic acids but lacking sulfur were used to chelate oxaliplatin prodrug which self-assembled into micelles in water for drug delivery.
Coalescence sensitivity to surface wettability and pore size of roughened stainless steel felt was revealed for oil-in-water emulsion separation.
A one-step method for the synthesis of water soluble fluorescent copper nanoparticles stabilized by 3-mercaptopropoic acid and histidine for detection of manganese ions.
The contact angle of a cylindrical nanodrop on a nanorough solid surface is calculated, for both hydrophobic and hydrophilic surfaces, using the density functional theory. The emphasis of the paper is on the dependence of the contact angle on roughness. The roughness is modeled by rectangular pillars of infinite lengt…
We investigate the operation of multitip silicon field emitters with new-type bilayer metal—fullerene protective coatings in technical vacuum. The experiments indicate that such cathodes ensures emission current densities averaged over the cathode surface of about 0.5 A/cm 2 and can be used in high-voltage devices inc…
Four different conjugated polymer nanoparticles (CPNs) were used to differentiate structurally similar glycosaminoglycans (GAGs) in a urine simulant. Unique emission response patterns of CPNs were analyzed by linear discriminant analysis (LDA), confirming that structurally diverse CPNs are sensitive and effective at d…
Unique H-bonding motifs of 1,3-dihydroxyl derivatives involving simultaneous intra- and inter-molecular H-bonding results in extended organization of pendant chromophores with a spatial distance suitable for π-π interaction. A preformed assembly with appended acceptor units exhibits host-guest interaction with specifi…
Small gold nanoparticles (AuNPs) that possess interfacial methyl-2-(diphenylphosphino)benzoate moieties have been successfully synthesized (Staudinger-AuNPs) and characterized by multi-nuclear MR spectroscopy, transmission electron microscopy (TEM), UV-Vis spectroscopy, thermogravimetric analysis, and X-ray photoelect…
By using low generation dendrimers as macromonomers, two main chain dendronized hyperbranched polymers, with good comprehensive nonlinear optical performance, were prepared conveniently with satisfying yields through a one-pot “A <sub>3</sub> + B <sub>2</sub> ” approach.
Colourless solutions of blue light-emitting, water-soluble gold nanoclusters (AuNC) were synthesized from gold colloids under microwave irradiation using small organic molecules as ligands. Stabilized by 1,3,5-triaza-7-phosphaadamantane (TPA) or L-glutamine (GLU), fluorescence quantum yields up to 5% were obtained. Au…
