Pushing the performance of image scanning microscopy to its limits with maximum likelihood reconstruction [PDF]

open access: yesEPJ Web of Conferences, 2023
Fast and sensitive detector arrays make Image Scanning Microscopy (ISM) the natural successor of confocal microscopy. Indeed, ISM enables super-resolution at an excellent signal-to-noise ratio. Optimizing photon collection requires large detectors and so

Raman spectroscopy as a versatile tool for studying the properties of graphene. [PDF]

open access: yesNature Nanotechnology, 2013
Raman spectroscopy is an integral part of graphene research. It is used to determine the number and orientation of layers, the quality and types of edge, and the effects of perturbations, such as electric and magnetic fields, strain, doping, disorder and

Reorientation-induced relaxation of free OH at the air/water interface revealed by ultrafast heterodyne-detected nonlinear spectroscopy

open access: yesNature Communications, 2020
Water’s hydrogen-bond network is truncated at hydrophobic interfaces and the dynamics of the resulting free OH groups is not well understood. The authors experimentally show that the main vibrational relaxation mechanism for free OH at the air-water ...

Separation of surface oxide from bulk Ni by selective Ni 3p photoelectron spectroscopy for chemical analysis in coincidence with Ni M-edge Auger electrons

open access: yesScientific Reports, 2021
The chemical shift of core level binding energies makes electron spectroscopy for chemical analysis (ESCA) a workhorse analytical tool for science and industry. For some elements, close lying and overlapping spectral features within the natural life time

Distance-Dependent Plasmon-Enhanced Fluorescence of Submonolayer Rhodamine 6G by Gold Nanoparticles

open access: yesNanoscale Research Letters, 2021
We investigate the fluorescence from submonolayer rhodamine 6G molecules near gold nanoparticles (NPs) at a well-controlled poly (methyl methacrylate) (PMMA) interval thickness from 1.5 to 21 nm.

Dual-comb optical activity spectroscopy for the analysis of vibrational optical activity induced by external magnetic field

open access: yesNature Communications, 2023
Dual-comb spectroscopy was first applied to the measurement of magnetic optical activity spectroscopy, realizing Doppler-limited gas-phase molecular analysis, and was further extended to the rapid measurement of liquid-phase chiroptical activity.

Quantifying defects in graphene via Raman spectroscopy at different excitation energies. [PDF]

open access: yesNano letters (Print), 2011
We present a Raman study of Ar(+)-bombarded graphene samples with increasing ion doses. This allows us to have a controlled, increasing, amount of defects.
