The BrightEyes-TTM as an open-source time-tagging module for democratising single-photon microscopy

Nature Communications, 2022
The authors developed an open-source, low-cost, multi-channel time-tagging module for fluorescence lifetime image scanning microscopy and correlation spectroscopy that can tag in parallel multiple single-photon events with 30 ps precision.

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,

Optical Spectroscopy of Molecular Positronium

Physical Review Letters, 2012
We report optical spectroscopic measurements of molecular positronium (Ps(2)), performed via a previously unobserved L=1 excited state. Ps(2) molecules created in a porous silica film, and also in vacuum from an Al(111) crystal, were resonantly excited and then photoionized by pulsed lasers, providing conclusive evidence for the production of this ...

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 ...
