2. 1. Atomistic simulation and experimental studies of transition metal systems involving carbon and nitrogen

   Author : Jiaying Xie; Seshadri Seetharaman; Oleg Ostrovski; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Transition metal carbides; Transition metal nitrides; Transition metal carbo-nitrides; Lattice inversion method; Interatomic potential; Atomistic simulation; Metallurgical process engineering; Metallurgisk processteknik;

   Abstract : The present work was initiated to investigate the stability, structural and thermodynamic properties of transition metal carbides, nitrides and carbo-nitrides by atomistic simulations and experimentations. The interatomic pair potentials of Cr-Cr, Mn-Mn, Fe-Fe, C-C, Cr-C, Mn-C, Fe-C, Cr-Fe, Cr-N and Mn-N were inverted by the lattice inversion method and ab initio cohesive energies, and then employed to investigate the properties of Cr-, Mn- and Fe-carbides by atomistic simulations in this work.

4. 2. Coarse-grained and atomistic modelling of phosphorylated intrinsically disordered proteins

   Author : Ellen Rieloff; Beräkningskemi; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; intrinsically disordered proteins; phosphorylation; simulations; Monte Carlo; molecular dynamics; coarse-graining; atomistic; statherin; small-angle X-ray scattering; circular dichroism;

   Abstract : Intrinsically disordered proteins (IDPs) are involved in many biological processes such as signalling, regulation and recognition. One of the main questions regarding IDPs is how sequence, structure and function are related. READ MORE

6. 4. Fighting microbial infections with force fields: Evaluating conformational ensembles of intrinsically disordered proteins

   Author : Stephanie Jephthah; Beräkningskemi; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; molecular dynamics; force field; Monte Carlo; coarse-grained modeling; simulation; intrinsically disordered protein; histatin 5; small-angle x-ray scattering; circular dichroism; atomistic MD simulations; all-atom protein models;

   Abstract : The main goal of this compilation thesis has been to investigate the conformational ensemble of the intrinsically disordered protein (IDP) histatin 5 by using a mixture of experimental and computational techniques including, but not limited to, small-angle X-ray scattering (SAXS), circular dichroism (CD) spectroscopy, atomistic molecular dynamics (MD) simulations, and coarse-grained Monte Carlo (MC) simulations. Histatin 5 is a peptide of particular interest for two reasons. READ MORE

7. 5. Modeling and simulation of intrinsically disordered proteins

   Author : Joao Henriques; Beräkningskemi; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Intrinsically disordered proteins; Coarse-grained models; Atomistic models; Metropolis Monte Carlo simulations; Molecular dynamics simulations; Sampling; Conformational analysis; Charge regulation; Surface adsorption;

   Abstract : This work is primarily about the development, validation and application of computer simulation models for intrinsically disordered proteins, both in solution and in the presence of uniformly charged, ideal surfaces. The models in question are either coarse-grained or atomistic in nature, and their applications are dependent on the specific purpose of each study. READ MORE
