Loosely-bound low-loss surface plasmons in hyperbolic metamaterial

open access: yesNano Convergence, 2018
Surface plasmons (SPs) carry electromagnetic energy in the form of collective oscillation of electrons at metal surface and commonly demonstrate two important features: strong lateral confinement and short propagation lengths.

Shape-altering flexible plasmonics of in-situ deformable nanorings

open access: yesNano Convergence, 2023
Nanorings (NRs) with their intrinsic cavities have attracted interest as plasmonic nanoparticles for years, due to the uniform electric field enhancement inside the cavity, lower plasmon damping effects and comparatively high refractive index ...

Inner structure- and surface-controlled hollow MnO nanocubes for high sensitive MR imaging contrast effect

open access: yesNano Convergence, 2020
Manganese oxide (MnO) nanocubes were fabricated and their surface were modified by ligand encapsulation or ligand exchange, to render them water-soluble. And then, MnO formed the hollow structure by etching using acidic solution (phthalate buffer, pH 4.0)

Order Convergence and Topological Convergence [PDF]

open access: yesProceedings of the American Mathematical Society, 1965
In a complete lattice it is possible to define a notion of convergence (for arbitrary nets) known as order convergence (o-convergence) ; for definitions see [l,p.5°]and [3, p. 65]. As a general rule o-convergence is not a topological convergence; i.e., the lattice cannot be topologized so that nets o-converge if and only if they converge with respect ...

Polymer-based chromophore–catalyst assemblies for solar energy conversion

open access: yesNano Convergence, 2017
The synthesis of polymer-based assemblies for light harvesting has been motivated by the multi-chromophore antennas that play a role in natural photosynthesis for the potential use in solar conversion technologies.

Electrochemical H2O2 biosensor based on horseradish peroxidase encapsulated protein nanoparticles with reduced graphene oxide-modified gold electrode

open access: yesNano Convergence, 2020
In this study, an electrochemical biosensor composed of a horseradish peroxidase (HRP)-encapsulated protein nanoparticles (HEPNP) was fabricated for the sensitive and selective detection of H2O2.

Perovskite single-crystal thin films: preparation, surface engineering, and application

open access: yesNano Convergence, 2023
Perovskite single-crystal thin films (SCTFs) have emerged as a significant research hotspot in the field of optoelectronic devices owing to their low defect state density, long carrier diffusion length, and high environmental stability.

Relationship between hepatocellular carcinoma circulating tumor cells and tumor volume

open access: yesCancer Convergence, 2018
Background Microfluidic platforms have demonstrated the ability to isolate rare circulating tumor cells from a wide variety of cancers. Our group has recently shown the ability to isolate circulating tumor cells (CTCs) from hepatocellular carcinoma (HCC)
