  1. 1. Aromatic Ring Flips and Local Volume Fluctuations in BPTI

    University essay from Lunds universitet/Biofysikalisk kemi

    Author : Simon Enbom; [2022]
    Keywords : Biophysical Chemistry; Molecular Dynamics; Protein Dynamics; Activation Volume; Aromatic Ring Flips; BPTI; Biology and Life Sciences; Chemistry; Technology and Engineering;

    Abstract : Aromatic ring flips are a classic example of a dynamic process in proteins. Discovered decades ago, methodological limitations hindered progress at the time. Ring flips have gained new interest and experimentalists can measure the flip rate and thermodynamic quantities associated with it. READ MORE

  2. 2. Doping Layers in Quantum Cascade Lasers: A study in doping density, position and migration effects

    University essay from Lunds universitet/Matematisk fysik

    Author : Josefin Reftlér; [2022]
    Keywords : Physics and Astronomy;

    Abstract : Quantum Cascade Lasers (QCLs) consist of several semiconductor materi- als sandwiched together. The QCL achieves stimulated emission in the mid-IR (m-IR) to the THz region of the electromagnetic spectrum by inter-subband transitions. These parts of the electromagnetic spectrum are hard to lase in with conventional means. READ MORE

  3. 3. Development of a novel quantitative PCR analysis method for HIV-1

    University essay from Lunds universitet/Tillämpad biokemi; Lunds universitet/Teoretisk kemi

    Author : Anna-Malin Hallberg; [2021]
    Keywords : HIV; PCR; primers; probes; virus; detection; blood plasma; pathogen; biological pharmaceutical; protein-based pharmaceutical; genotype; subtype; RT qPCR; extraction; TaqMa; RNA virus; cross-dimer; applied biochemistry; tillämpad biokemi; Biology and Life Sciences; Technology and Engineering; Chemistry;

    Abstract : Biological pharmaceuticals are the answer to many severe diseases of today’s society. Some of these are protein-based drugs and can be produced from human blood plasma. In order to guarantee the safety of patients, absence of any pathogens needs to be ensured. READ MORE

  4. 4. Molecular insight into ion interactions at charged interfaces exposing sulfonate headgroups

    University essay from KTH/Yt- och korrosionsvetenskap

    Author : Hugo Widehammar; [2021]
    Keywords : Langmuir monolayers; Vibrational Sum Frequency Spectroscopy; Fatty sulfonic acid; Monovalent ions; Poisson Boltzmann theory; Langmuir monolager; vibrations sumfrekvens spektroskopi; fettsulfonsyra; monovalenta joner; Poisson Boltzmann teori;

    Abstract : Hur elektrolytlösningar interagerar med laddade ytor är viktigt för många fenomen. I detta arbete undersöktes samspelet mellan flera joner med en negativt laddad yta som exponerade sulfonat funktionella grupper mot lösning. Särskild vikt lades på deprotoneringsbeteendet vid ytan.

  5. 5. Analysis of stellar spectra with machine learning

    University essay from Lunds universitet/Institutionen för teoretisk fysik; Lunds universitet/Astronomi; Lunds universitet/Institutionen för astronomi och teoretisk fysik

    Author : Alvaro Segovia Otero; [2020]
    Keywords : Galactic Archaeology; machine learning; chemical abundances; FGK stars; Physics and Astronomy;

    Abstract : Researchers in the field of Galactic Archaeology have entered the era of industrial revolution. Upcoming surveys are planning on observing tens of millions of stars and high precision and accuracy must be ensured when deriving their stellar parameters and elemental abundances. READ MORE
