Phonon-Enhanced Mid-Infrared CO2 Gas Sensing Using Boron Nitride Nanoresonators
(ACS, 2022-01-05)
Article
Open AccessHexagonal boron nitride (hBN) hosts long-lived phonon polaritons, yielding a strong mid-infrared (mid-IR) electric field enhancement and concentration on the nanometer scale. It is thus a promising material for highly ... -
Controlling mid-infrared plasmons in graphene nanostructures through post-fabrication chemical doping
(IOP, 2021-05-07)
Article
Open AccessEngineering the doping level in graphene nanostructures to yield controlled and intense localized surface plasmon resonance (LSPR) is fundamental for their practical use in applications such as molecular sensing for point ... -
Mid-infrared Gas Sensing Using Graphene Plasmons Tuned by Reversible Chemical Doping
(ACS, 2020-03-18)
Article
Open AccessHighly confined plasmon modes in nanostructured graphene can be used to detect tiny quantities of biological and gas molecules. In biosensing, a specific biomarker can be concentrated close to graphene, where the optical ... -
Antireflective Transparent Oleophobic Surface by Non-Interacting Cavities
(ACS, 2018-11-16)
Article
Open AccessOleophobic surfaces have been so far realized using complex micro-scale and nano-scale reentrant geometries where primary and secondary structures or overhang geometries are typically required. Here we propose a new ... -
Multimilliwatt, tunable, continuous‐wave, mid‐infrared generation across 4.6‐4.7 m based on orientation‐patterned gallium phosphide
(OSA, 2018-05-06)
Article
Open AccessWe report the generation of tunable continuous-wave (cw) mid-infrared (mid-IR) radiation across 4608–4694 nm using the new nonlinear material, orientation-patterned gallium phosphide (OP-GaP). By exploiting difference-frequency ... -
Structural Coloring of Glass Using Dewetted Nanoparticles and Ultrathin Films of Metals
(ACS, 2016-04-22)
Article
Open AccessMetal nanoparticles have been used for coloring glass since antiquity. Colors are produced by light scattering and absorption associated with plasmon resonances of the particles. Recently, dewetting at high temperature has ... -
Dry transfer of graphene to dielectrics and flexible substrates using polyimide as a transparent and stable intermediate layer
(IOP, 2018-04-30)
Article
Open AccessWe demonstrate the direct transfer of graphene from Cu foil to glass and flexible substrates such as PET, using polyimide (PI) mixed with an aminosilane (3-aminopropyltrimethoxysilane) or only PI, respectively, as intermediate ... -
Phase-sensitive plasmonic biosensor using a portable and large field-of-view interferometric microarray imager
(Nature, 2018-02-23)
Article
Open AccessNanophotonics, and more specifically plasmonics, provides a rich toolbox for biomolecular sensing, since the engineered metasurfaces can enhance light–matter interactions to unprecedented levels. So far, biosensing ... -
Effects of fullerene on lipid bilayers displaying different liquid ordering: a coarse-grained molecular dynamics study
(ScienceDirect, 2017-08-02)
Article
Open AccessBackground The toxic effects and environmental impact of nanomaterials, and in particular of Fullerene particles, are matters of serious concern. It has been reported that fullerene molecules enter the cell membrane and ... -
Double-layer graphene for enhanced tunable infrared plasmonics
(Nature, 2017-06-02)
Article
Open AccessGraphene is emerging as a promising material for photonic applications owing to its unique optoelectronic properties. Graphene supports tunable, long-lived and extremely confined plasmons that have great potential for ... -
Functionalized Transparent Surfaces with Enhanced Self-Cleaning against Ink Aerosol Contamination
(Wiley, 2016-10-26)
Article
Open AccessDuring operation of a standard commercial inkjet printer, suspended ink particles form an ink aerosol inside the printing chamber that can cause serious malfunctions, including contamination of the transparent window of ... -
Direct growth of 2D and 3D graphene nano-structures over large glass substrates by tuning a sacrificial Cu-template layer
(IOP, 2017-03-28)
Article
Open AccessWe demonstrate direct growth of two-dimensional (2D) and three-dimensional (3D) graphene structures on glass substrates. By starting from catalytic copper nanoparticles of different densities and using chemical vapour ...
