s2ISM: A Comprehensive Approach for Uncompromised Super-Resolution and Optical Sectioning in Image Scanning Microscopy [PDF]

EPJ Web of Conferences
Image Scanning Microscopy (ISM) enables good signal-to-noise ratio (SNR), super-resolution and high information content imaging by leveraging array detection in a laser-scanning architecture. However, the SNR is still limited by the size of the detector,

Exploiting volumetric wave correlation for enhanced depth imaging in scattering medium

Nature Communications, 2023
The authors achieve ultrahigh resolution and depth volumetric imaging in complex media by recording a volumetric reflection matrix covering individual wavelengths and angles and developing reconstruction algorithms based on volumetric wave correlation.

Reconstruction and regularization approaches for photon-resolved image scanning microscopy [PDF]

EPJ Web of Conferences
Fast, sensitive detector arrays make Image Scanning Microscopy (ISM) a natural successor to confocal laser scanning microscopy (CLSM), enabling super-resolution (SR) with excellent signal-to-noise ratio (SNR).

Two-dimensional electronic spectroscopy of bacteriochlorophyll a with synchronized dual mode-locked lasers

Nature Communications, 2020
Multidimensional electronic spectroscopy techniques still have many limitations. Here, the authors introduce a 2D electronic spectroscopy technique that uses broadband, synchronized mode-locked lasers to study dynamics on a wide range of timescales.

Macroscopic conductivity of aqueous electrolyte solutions scales with ultrafast microscopic ion motions

Nature Communications, 2020
The ionic conductivity of an aqueous electrolyte has a great impact on the performance of devices such as batteries. Here, the authors advance our understanding by showing that a high macroscopic conductivity originates from the large-amplitude sub ...

Coupling between intra- and intermolecular motions in liquid water revealed by two-dimensional terahertz-infrared-visible spectroscopy

Nature Communications, 2018
Liquid water molecules are in constant vibrational motion, but probing how their local behaviour influences collective dynamics remains a challenge.

Ion-specific binding of cations to the carboxylate and of anions to the amide of alanylalanine

Communications Chemistry, 2022
Studies of ion-specific effects on oligopeptides are largely dependent on model peptides and experimental sensitivities. Here, the authors study the ion-specific effects on L-alanyl-L-alanine by combining dielectric relaxation, 1H-NMR and 2D infrared ...

Unified picture of vibrational relaxation of OH stretch at the air/water interface

Nature Communications
The elucidation of the energy dissipation process is crucial for understanding various phenomena occurring in nature. Yet, the vibrational relaxation and its timescale at the water interface, where the hydrogen-bonding network is truncated, are not well ...

Hyperglycemia and cancer in human lung carcinoma by means of Raman spectroscopy and imaging

Scientific Reports, 2022
Raman spectroscopy and Raman imaging were used to identify the biochemical and structural features of human cancer lung cells (CCL-185) and the cancer cells supplemented with glucose and deuterated glucose at normal and hyperglycemia conditions. We found
