  1. 1. Optical Communication using Nanowires and Molecular Memory Systems

    University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Synkrotronljusfysik

    Author : Thomas Kjellberg Jensen; [2024]
    Keywords : neuromorphic computing; nanowire; molecular dye; DASA photoswitch; OBIC; Physics and Astronomy;

    Abstract : Neuromorphic computational networks, inspired by biological neural networks, provide a possible way of lowering computational energy cost, while at the same time allowing for much more sophisticated devices capable of real-time inferences and learning. Since simulating artificial neural networks on conventional computers is particularly inefficient, the development of neuromorphic devices is strongly motivated as the reliance on AI-models increases.

    Keywords : Photosensitizer proteins; QM MM; photophysics; molecular dynamics; computational protocol for protein preparation; Fotosensibiliserande proteiner; QM MM; fotofysik; molekylär dynamik; beräkningsprotokoll för förberedelser av proteiner;

    Abstract : Den ökande koldioxidhalten i atmosfären har lett till ett ökat intresse för användning av solljus, ett exempel är inom kemi. Att använda ljus i kemi kan leda till nya och intressanta kemiska reaktioner och kan tillämpas i användningsområden som exempelvis fotokatalys och fotovoltaik. READ MORE

  3. 3. Photophysics of the polymer acceptor PF5-Y5 in organic photovoltaics : A first principles theory based study

    University essay from Karlstads universitet/Institutionen för ingenjörsvetenskap och fysik (from 2013)

    Author : Anton Almén; [2022]
    Keywords : PF5-Y5; Non-fullerene-acceptor; NFA; polymer; fundamental; optical; gap; oxidation; reduction; exciton; binding; energy; oligomer; length; PF5-Y5; Non-fullerene-acceptor; NFA; polymer; fundamentalt; optiskt; gap; oxidation; reduktion; exciton; binding; energi; oligomerlängd;

    Abstract : Non-fullerene Acceptors (NFAs) have gathered a great deal of interest for use inorganic photovoltaics (OPVs) due to recent breakthroughs in their power conversion efficiency and other advantages they offer over their Fullerene-based counterparts. In this work, a new promising non-fullerene polymer acceptor, PF5-Y5, have been studied using density functional theory and time-dependent density functional theory; and the effects that oligomer length, geometry relaxation and exchange-correlation interaction has on the exciton binding energies (the difference between optical and fundamental energy gaps) have been investigated.

  4. 4. Improving the temporal resolution of a microspectrometer for the study of the photophysics of enhanced green fluorescent protein

    University essay from KTH/Tillämpad fysik

    Author : Lukas Rane; [2021]
    Keywords : Biophysics; EGFP; Fluorescence; triplet state; Biofysik; EGFP; fluorescens; triplet tillstånd;

    Abstract : The use of fluorescent proteins as fluorescent markers has exploded over the last decades. In particular due to the development of advanced microscopy for live cell measurements, dynamic molecular studies down to single molecule levels and for superresolution microscopy. READ MORE

  5. 5. Photophysics of blood on a crime scene

    University essay from KTH/Skolan för teknikvetenskap (SCI)

    Author : Patric Elf; [2018]
    Keywords : ;

    Abstract : The purpose of this study is to analyze the possibility to age-determine blood spots with the help of enzymes which blood contains, in order to see if with these results it's possible to give an estimate of how long it has been since blood left the body. The main domain of this would be that of a crime-scene in order to give a time-frame of when a crime has been commited. READ MORE
