1. Nanofluidics as a tool for parallelized single nanoparticle characterization: Fluorescence single nanoparticle catalysis and size determination through 1D Brownian motion
Abstract : Nanoparticles exist widely in nature and are objects of study in many scientific disciplines due to their high performance in a wide range of applications. With modern techniques that facilitate creating and shaping of nanoparticles into ever more complex shapes and compositions, characterization of particle properties is essential. READ MORE

2. Nanofluidic Scattering Microscopy for Single Particle Catalysis
Abstract : Heterogeneous catalysis concerns material formulations – catalysts – that can assist a chemical reaction by improving its rate or selectivity, by lowering activation barriers and altering the energy landscape. The core of catalysts are often tiny metal particles that provide a large reaction surface at a small volume, as well as low coordination sites whose type and abundance depends on particle size and shape.

3. Operando Single Particle Catalysis - Combining a Nanoreactor and Plasmonic Nanospectroscopy
Abstract : Heterogeneous catalysis is an important cornerstone of modern society with strong ties to the development of sustainable sources of energy and products. Catalysts are typically realized as supported metal nanoparticles that offer active sites that can accelerate chemical reactions by providing energetically more favorable reaction paths. READ MORE

4. Kinetics of Nanoparticle Catalysis from First Principles
Abstract : Modern society depends heavily on heterogeneous catalysis, which creates strong economical and environmental incentives to improve catalyst efficiency. Heterogeneous catalysts are often realized as metal nanoparticles (NPs) supported on oxide surfaces, and catalysts are traditionally developed by trial and error approaches. READ MORE

5. Studies of Molecular Interactions with Single Nanoparticles: Combining in Situ Plasmonic Nanospectroscopy with Transmission Electron Microscopy
Abstract : The cyclic methanol and hydrogen economies are two viable options in the strive for clean energy production. Industrial methanol synthesis is conducted over copper (Cu)-based catalysts. However, Cu is prone to oxidation, which leads to Cu catalyst deactivation. READ MORE
