Fluorometer system, fluorescene analysis method, and use thereof
Christoph Merten, Jatin Panwar
The invention relates to a fluorometer system for analyzing fluid samples comprising a plurality of particles capable of being labeled with at least two fluorescent labels, in particular two distinct fluorophores. The invention also relates to a fluorescen ...
2024III-N blue-emitting epi-structures with high densities of dislocations: Fundamental mechanisms for efficiency improvement and applications
Since the dawn of humanity, human beings seeked to light their surroundings for their well-being, security and development. The efficiency of ancient lighting devices, e.g. oil lamps or candles, was in the order of 0.03-0.04% and jumped to 0.4-0.6% with th ...
EPFL2024Thermo-hydro-mechanical behaviour of the Callovo-Oxfordian claystone under thermal changes
Underground storage of radioactive waste is consensually recognised as the safest storage solution by European and worldwide countries relying mainly or partially on nuclear energy production. Over twenty years of research led by the French national agency ...
EPFL2024Wideband integrated bioaerosol sensor (WIBS) excited, fluorescent, and hyper-fluorescent particle number concentrations and normalized size distributions (dN/dlogDp) measured in the Swiss container during MOSAiC 2019/2020
Julia Schmale, Ivo Fabio Beck, Alireza Moallemi, Margarida Teles Nogueira Rolo
These datasets contain the total particle number concentrations and normalized size distributions (dN/dlogDp) of excited, fluorescent, and hyper-fluorescent particles of sizes 0.5 to 20 μm (optical diameter). The normalized size distribution datasets are s ...
EPFL Infoscience2023Sources and seasonality of fluorescent aerosols in the Arctic
Julia Schmale, Ivo Fabio Beck, Benjamin Jérémy Laurent Heutte, Nora Bergner, Alireza Moallemi
Aerosol‐cloud interactions play an important role in the Arctic climate but remain poorly understood. Ice nucleating particles (INPs) contribute to the formation of ice crystals at temperatures above ‐38 °C in mixed phase clouds, which are predominant in t ...
2023Multivalent Peptide Ligands To Probe the Chromocenter Microenvironment in Living Cells
Beat Fierz, Pablo Rivera Fuentes, Nora Guidotti, Maxime Nicolas Mivelaz, Adam Miklos Eördögh
Chromatin is spatially organized into functional states that are defined by both the presence of specific histone post-translational modifications (PTMs) and a defined set of chromatin-associated “reader” proteins. Different models for the underlying mecha ...
2022Visual comfort without borders: Extending daylight glare prediction to dim daylit environments
Avoiding discomfort glare is one of the critical aspects of maintaining visual comfort, which significantly influences occupants' overall satisfaction with their indoor environment. Discomfort glare prediction models have been developed for various lightin ...
EPFL2022Insights about inductively coupled plasma optical emission spectroscopy interferences of major rare earth elements in complex e-waste feeds
Christian Ludwig, Rudolf Paul Wilhelm Jozef Struis, Ajay Bhagwan Patil, Mohamed Tarik
The advent of rare earth elements (REEs) with optoelectronic properties has shifted the technology paradigm from digital to a smart and hybrid world. Their substantial uses also resulted in a large piling up of e-waste. Therefore, e-waste is now a lucrativ ...
2022Exploiting end-of-life lamps fluorescent powder e-waste as a secondary resource for critical rare earth metals
Christian Ludwig, Rudolf Paul Wilhelm Jozef Struis, Ajay Bhagwan Patil, Mohamed Tarik
The consensus is growing for the UN sustainable development goals regarding responsible consumption, production, and climate actions. Because of growth towards a digital society (“industry 4.0 revolution”), it is needed to have our resources and economies ...
2021Validation of Spectral Simulation Tools for the Prediction of Indoor Electric Light Exposure
Marilyne Andersen, Clotilde Marie A Pierson, Myrta Gkaintatzi-Masouti
As the interest in design applications related to responses to light beyond vision is growing, two simulation tools, ALFA and Lark, have been developed to incorporate spectral characteristics of light in the evaluation of indoor lighting conditions. The sp ...
