1. 16. Microgels as drug carriers : Relationship between release kinetics and self-aggregation of the amphiphilic drugs adiphenine, pavatrine and diphenhydramine.

   University essay from Uppsala universitet/Institutionen för läkemedelskemi

   Author : Lobna Ali Mohsen; [2021]
   Keywords : Amphiphilic drugs; small angle x-ray scattering; macrogels; binding isotherm; CMC; self-aggregation; phase structure; micelles.;

   Abstract : Abstract There has been great interest in microgels as drug carriers within the pharmaceutical industry. This includes the use of amphiphilic drugs for treating conditions such as depression, allergies, and cancer. READ MORE

3. 17. An investigation of the interactions between clay nanoplatelets in the presence of monovalent and divalent salts, as well as cationic peptides utilising atomistic molecular dynamics

   University essay from Lunds universitet/Kemiska institutionen

   Author : Mona Koder Hamid; [2020]
   Keywords : clay; molecular dynamics simulations; physical chemistry; fysikalisk kemi; theoretical chemistry; teoretisk kemi; Chemistry;

   Abstract : Clays are negatively charged nanoplatelets with a layered silicate structure. It has been observed from small angle X-ray scattering measurements, and coarse-grained molecular dynamics simulations (CG-MD) that clay nanoplatelets are able to form stacks, known as tactoids, in the presence of divalent or multivalent counterions [8, 5].

4. 18. Investigating the role of water in the protein dynamic transition

   University essay from Stockholms universitet/Fysikum

   Author : Maddalena Bin; [2020]
   Keywords : Protein; water; protein dynamic transition; x-ray;

   Abstract : Proteins undergo a dynamic transition at approximately 220 K, also called protein ’glass’ transition, below which temperature proteins lose their conformational flexibility and become biologically inactive. The protein dynamic transition has been observed for several proteins utilizing different techniques, such as inelastic neutron scattering, infrared spectroscopy and X-ray crystallography. READ MORE

5. 19. Chaos in Stellar Dynamics - Outcomes of Binary-Single interactions in Globular Clusters

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

   Author : Lucas Hellström; [2020]
   Keywords : Stellar Dynamics; Binary-Single interactions; Dynamical encounters; Additional processes; Physics and Astronomy;

   Abstract : Gravitational encounters between a single star and a binary system can frequently occur in the cores of dense stellar systems like globular clusters. These three-body scattering encounters can lead to a variety of outcomes since the energy of the binary components can be exchanged with the interacting single star. READ MORE

6. 20. Biophysical differences between COPD, CF and healthy airways mucus.

   University essay from Malmö universitet/Fakulteten för hälsa och samhälle (HS)

   Author : Vladislav Genevskiy; [2020]
   Keywords : CF; COPD; mucus; structure;

   Abstract : An improved understanding of the mucus biophysical alteration in chronic obstructive pulmonary disease (COPD) and cystic fibrosis (CF) patients is a milestone towards a more accurate and effective treatment of these common and highly debilitating conditions. Little is known about the variations in mucus structure between ill and healthy individuals. READ MORE
