Linked plasmonic nanoparticles made of noble metal materials exhibit significant enhancement of the amplitude of electromagnetic-field and strongly frequency-selective response at visible ranges which are distinct from that of individual nanoparicles. We introduce recent progress in the fabrication processes to achieve linked plasmonic nanostructures with various configurations. It includes the...

Highly active, durable, and cost-effective electrocatalysts for water oxidation to evolve oxygen gas hold a key to a range of renewable energy solutions, including water-splitting and rechargeable metal-air batteries. Here, we report the synthesis of ultrathin nickel-iron layered double hydroxide (NiFe-LDH) nanoplates on mildly oxidized multiwalled carbon nanotubes (CNTs). Incorporation of Fe i...

The lateral dimensions of CdSe nanoplatelets have a strong and unique influence on their opto-electronic properties, with sizes that can be tuned from the weak to the strong exciton confinement regime. There are state-of-the-art reports on several nanoplatelet syntheses; however, at present only the thickness is well-controlled. We demonstrate here that we can achieve a control over the aspect ...

Electron energy-loss magnetic chiral dichroism is a powerful technique that allows the local magnetic properties of materials to be measured quantitatively with close-to-atomic spatial resolution and element specificity in the transmission electron microscope. Until now, the technique has been restricted to measurements of the magnetic circular dichroism signal in the electron beam direction. H...

In this article, surface stress and nonlocal effects on the biaxial and uniaxial buckling of rectangular silver nanoplates embedded in elastic media are investigated using finite difference method (FDM). The uniform temperature change is utilized to study thermal effect. The surface energy effects are taken into account using the Gurtin-Murdoch’s theory. Using the principle of virtual work, the...

In this paper, the wave propagation method is combined with nonlocal elasticity theory to analyze the buckling and free vibration of rectangular Reddy nanoplate. Wave propagation is one of the powerful methods for analyzing the vibration and buckling of structures. It is assumed that the plate has two opposite edges simply supported while the other two edges may be simply supported or clamped. ...

A heterojunction AgBr/Ag/AgCoO2 nanocomposite was synthesized by hydrothermal followed deposition precipitation method. The morphology, crystallinity and band structure of the nanoparticles were characterized using scanning electron microscopy (SEM), X-ray diffraction (XRD) UV–Vis diffuse reflectance spectroscopy (UV DRS). beads prepared coating material on petrocoke with aid chitosan. performa...
