High catalytic performance of Ni/La 0.8 Sr 0.2 AlO 3 catalyst due to high amount of mobile lattice oxygen which favors direct partial oxidation of toluene while gas-phase oxygen favors complete oxidation. Both oxygen species actively oxidize coke deposited on catalyst surface, conferring coking resistance.
Polyaniline-functionalized graphene quantum dots (PANI-GQD) and pristine graphene quantum dots (GQDs) were utilized for optoelectronic devices. The PANI-GQD based photodetector exhibited higher responsivity which is about an order of magnitude at 405 nm and 7 folds at 532 nm as compared to GQD-based photodetectors. Th…
Electrospinning techniques are used to produce novel nanoscale fibrous materials used in a diverse range of applications. Electrospinning: Principles Practice and Possibilities provides a snapshot of the current cutting edge developments of the field. The first chapter introduces readers to electrospinning, followed b…
In this work niclosamide was encapsulated into albumin nanoparticles through a desolvation method to improve its scope of application in cancer therapy.
Fusion of one or two phenalenyl units onto the porphyrin core led to biradicaloids with different ground state, physical property and chemical reactivity.
Single-crystalline ceria nanorods were fabricated using a hydrothermal process and annealed at 325 °C-800 °C. As-synthesized CeO2 nanorods contain a high concentration of defects, such as oxygen vacancies and high lattice strains. Annealing resulted in an improved lattice crystalline quality along with the evolution o…
Three mechanisms for CO catalytic oxidation on Al-doped g-ZnO monolayer sheets were comparably studied, among which the Eley–Rideal mechanism is both energetically and dynamically more favorable.
High-voltage electric double layer capacitors (EDLCs) capable of efficient AC line-filtering have been developed. They were fabricated with vertically-oriented graphene nanosheet (VOGN) electrodes using a planar design. Two approaches were examined to series connect EDLC cells and thus achieve high-voltage operation.…
Five POM-based metal–organic complexes ranging from 0D trinuclear cluster, 1D chain, 2D network, to 3D framework have been successfully prepared in the presence/absence of citric or boric acid.
Flexible paper-like semiconductor nanowire materials are expected to meet the criteria for some emerging applications, such as components of flexible solar cells, electrical batteries, supercapacitors, nanocomposites, bendable or wearable electronic or optoelectronic components, and so on. As a new generation of wide-…
We present here the film-type chemosensors based on stimuli-responsive emissive polymers composed of boron diiminate. Hydrogen peroxide can be monitored by the emission enhancement.
Dual-layer nitrofurazone-loaded nanofiber mats are fabricated by electrospinning with good antibacterial activity and the mats perform well in wound healing.
A new nanocluster of atomic precision, Au44(SC2H4Ph)32, is obtained by an oxidation-decomposition-recombination (ODR) process from Au25(SC2H4Ph)18 under mild conditions with high yield (75%). Among the investigated gold nanoclusters, Au44(SC2H4Ph)32 exhibits the highest catalytic activity for the reduction of 4-nitrop…
A hydrophobic/oleophilic surface when immersed in water can result in an oleophilic or “Cassie” state of oil-wetting.
Dendrimer-like silica particles with a center-radial dendritic framework and a synergistic hierarchical porosity have attracted much attention due to their unique open three-dimensional superstructures with high accessibility to the internal surface areas; however, the delicate regulation of the hierarchical porosity…
Highly ordered mesoporous MnO 2 was prepared using KIT-6 as a hard template, for selective catalytic reduction (SCR) of NO with NH 3 at low temperature, which was characterized using TEM, XRD, BET, XPS, H 2 -TPR, NH 3 -TPD and in situ DRIFT.
The chicken feather-derived N-doped porous carbons exhibit excellent electrochemical performance and high CO 2 uptake.
The formation and characterization of shrimp shell-derived CaO nano-plates with antibacterial activity have been demonstrated in this communication.
In this review we describe the use of monolayer protected gold nanoparticles (Au NPs) for chemosensing applications. The attention is focused on a special subclass of Au NPs, namely those that contain binding sites for metal ions in the monolayer. It will be shown that these systems are very well-equipped for metal io…
Five members of a new family of polyoxometalate (POM)-ligated trinuclear lanthanoid (Ln) clusters with the general formula K20Li2[Ln3(μ3-OH)(H2O)8(AsW9O33)(AsW10O35(mal))]2·17H2O [Ln = Dy (1Dy), Tb (2Tb), Gd (3Gd), Eu (4Eu), and Sm (5Sm), mal = malate] have been synthesized, all of which consist of the dimeric {[Ln3(μ…
