Abstract:

AbstractNanoporous metals (NPMs) made by dealloying represent a class of functional materials with the unique structural properties of mechanical rigidity, electrical conductivity, and high corrosion resistance. They also possess a porous network structure with feature dimensions tunable within a wide range from a few nanometers to several microns. Coupled with a rich surface chemistry for further functionalization, NPMs have great potential for applications in heterogeneous catalysis, electrocatalysis, fuel cell technologies, biomolecular sensing, surface-enhanced Raman scattering (SERS), and

Abstract:

To enhance the optical and catalytic properties of TiO2, carbon nanodots (CNDs) are incorporated to prepare hybrid CNDs/TiO2 materials with different precursor concentrations and the photocatalytic characteristics are evaluated systematically. When the CNDs/TiO2 materials are excited optically, some high-energy photons are reabsorbed by those in the lower energy states, indicating that photon reabsorption of CNDs plays a key role. The results enrich our understanding of the optical and catalytic mechanisms and provide insight into the design of CNDs-based composites.

Abstract:

Abstract Anisotropic nanostructures with unique physical and chemical properties have been widely applied in optical, electronic, magnetic, and catalytic fields. This paper described the synthesis of hexagonal gold nanoplates (HAuNPs) by trisodium citrate and ascorbic acid. The optical and near-field distribution properties of hexagonal gold nanoplates were studied by discrete dipole approximation method. Simulation results showed that due to the shape anisotropy of HAuNPs, the optical properties of HAuNPs were significant differences between the horizontal orientation and vertical orientation

AbstractIn this work, poly (vinylcaprolactam-co-itaconic acid) microgel was prepared by free radical polymerization. Silver nanoparticles were prepared in synthesized microgel networks by in situ reduction of Ag+ ions, loaded in microgel from aqueous solution of AgNO3. The prepared microgel was characterized by Fourier transformation infra-red spectroscopy, UV-Visible spectroscopy, fluorescence spectroscopy, X-ray diffraction, laser light scattering, thermal gravimetric analysis, differential scanning calorimetry and transmission electron microscopy. Swelling behavior of microgel was studied a

Abstract:

Abstract Finite antimonene nanoribbons are investigated using density functional theory calculations. Attaching chemical groups, like COOH and OH, to the edges has been successfully attained with negligible deformation and moderate binding energy. They are semiconductors with energy gap ∼2.3 eV that slightly affected by attaching groups such as C2H5 or significantly decreases to 1.8 eV by attaching NO. The optical gaps, from 1.5 eV to 2 eV, are lower than the electronic ones which indicate the existence of excitonic transitions that appear due to the quantum confinement in the finite nanoribbo
