STM fluorescence of porphyrin enhanced by a strong plasmonic field and its nanoscale confinement in an STM cavity [PDF]

open access: yes, 2009
We have investigated scanning tunneling microscope-induced luminescence STML from porphyrin molecules by varying the tip PtIr, Ag, and Au/substrate Pt, Ag, Au, and indium tin oxide combinations. Strong molecular fluorescence by highest-occupied molecular

Magnetic properties of epsilon iron(III) oxide nanorod arrays functionalized with gold and copper(II) oxide [PDF]

open access: yes, 2018
A sequential chemical vapor deposition (CVD) - radio frequency (RF)-sputtering approach was adopted to fabricate supported nanocomposites based on the scarcely investigated \u3b5-iron(III) oxide polymorph.

Nanoaggregates of benzothiazole-based amidine-coupled chemosensors: a chemosensor for Ag+ and the resultant complex as a secondary sensor for Cl−

open access: yesRSC Advances, 2014
Nanoaggregates of benzothiazole-based amidines were prepared for study as sensors in aqueous medium. Sensor N2 was found to behave as a selective primary sensor for Ag+, and the subsequent complex N2·Ag+ acted as a secondary sensor for Cl− in aqueous medium through a cation displacement mechanism. The cation displacement mechanism was further supported

Local anisotropy and giant enhancement of local electromagnetic fields in fractal aggregates of metal nanoparticles

open access: yes, 2005
We have shown within the quasistatic approximation that the giant fluctuations of local electromagnetic field in random fractal aggregates of silver nanospheres are strongly correlated with a local anisotropy factor S which is defined in this paper.

Enhanced plasmonic behavior of bimetallic (Ag-Au) multilayered spheres [PDF]

open access: yes, 2011
In this article we study the plasmonic behavior of some stable, highly biocompatible bimetallic metal-dielectric-metal (MDM) and double concentric nanoshell (DCN) structures.

Photoelectrochemical CO2 reduction on CuO-Cu2O nanocomposites with noble metal co-catalysts enhances the production of C1 oxygenates and acetate

open access: yesNext Nanotechnology
Multi-junction copper oxide nanocomposite photocathodes formed by CuO nanowire arrays coated with Cu2O nanopyramids or stacked nanoprisms, i.e. CuO(NWA)|Cu2O(NPy), exhibit remarkable electrochemical stability toward reductive corrosion.

Ag-Vanadates/GO Nanocomposites by Aerosol-Assisted Spray Pyrolysis: Preparation and Structural and Electrochemical Characterization of a Versatile Material [PDF]

open access: yes, 2017
In this article, we describe the deposition by aerosol-assisted spray pyrolysis of different types of silver vanadate nanocomposites with and without graphene oxide (GO) on different substrates (carbon paper (CP) and fluorine-doped tin oxide (FTO)). When

Inelastic electron tunneling spectroscopy of nanoporous gold films

open access: yes, 2014
We investigated the localized electronic properties of nanoporous gold films by using an ultra-high vacuum scanning tunneling microscope at low temperature (4.2 K).

Excitonic Wave Function Reconstruction from Near-Field Spectra Using Machine Learning Techniques

open access: yes, 2019
A general problem in quantum mechanics is the reconstruction of eigenstate wave functions from measured data. In the case of molecular aggregates, information about excitonic eigenstates is vitally important to understand their optical and transport ...

Dynamic Mechanisms of the Bactericidal Action of an Al2O3-TiO2-Ag Granular Material on an Escherichia coli Strain. [PDF]

open access: yes, 2015
The bactericidal activity of an Al2O3-TiO2-Ag granular material against an Escherichia coli strain was confirmed by a culture-based method. In particular, 100% of microorganisms were permanently inactivated in 30 to 45 min.
