1. 1. Juice/JDC ion measurement perturbations caused by spacecraft charging in the solar wind and Earth’s magnetosheath

   University essay from Uppsala universitet/Institutionen för fysik och astronomi

   Author : Derek van Winden; [2024]
   Keywords : Juice; Jupiter Icy Moons Explorer; JDC; Jovian plasma Dynamics and Composition analyzer; Particle Environment Package; PEP; Jupiter; Ganymede; Callisto; Europa; solar wind; magnetosheath; spacecraft charging; Spacecraft Plasma Interaction Software; SPIS; charging; plasma; measurement perturbations; perturbation; distortion; particle detector; Institutet för Rymdfysik; IRF; Dublin Institute for Advanced Studies; DIAS; European Space Agency; ESA;

   Abstract :  In July 2031, a new chapter in the exploration of the Jovian system will begin with the arrival of the Jupiter Icy Moons Explorer (Juice) at Jupiter. Launched on April 14 2024 as part of ESA’s Cosmic Vision programme, the mission aims to study Jupiter and its icy Galilean moons Callisto, Europa, and Ganymede. READ MORE

3. 2. Ion pair chromatography of carboxylic and sulfonic acids with trialkylamines : An investigation of the relationship between the adsorption isotherm of the IPR and the retention factor of the analyte

   University essay from Karlstads universitet/Institutionen för ingenjörs- och kemivetenskaper (from 2013)

   Author : Karl Kullberg; [2023]
   Keywords : ;

   Abstract : Ion pair chromatography has found many uses within analytical chemistry and understanding of the chromatographic process with an ion-pairing reagent have been studied since the 1970s. The adsorption of the Ion-pairing reagent to the stationary phase is understood to be important and many studies have been dedicated to looking at the adsorption isotherms of the earlier quaternary alkylammonium ions.

4. 3. Design and Modeling of InxGa(1−x)As/InP based Nanosheet Field Effect Transistors for High Frequency Applications

   University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

   Author : Hanyu Liu; Xi Chen; [2023]
   Keywords : nanosheet NS ; gate-all-around GAA ; channel release; parasitic channel; MATLAB; COMSOL; technology node; Technology and Engineering;

   Abstract : The advancement of CMOS technology has been fueled by the need to satisfy Moore’s law by shrinking transistors to progressively smaller sizes and increasing the transistor density per unit area [1]. The dimension of the state-of-the-art MOSFET is now down to a few nanometers. READ MORE

5. 4. Statistics of Electric and Magnetic Fields at the Earth’s Bow Shock

   University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Author : Tsz-Kiu Wong-Chan; [2023]
   Keywords : MMS; Earth’s bow shock; Collisionless shocks; Correlation study; statistics; Space; Space plasma physics; MMS; Jordens bogchock; Kollisionsfria chocker; Korrelationsstudie; Statistik; Rymd; Rymdplasmafysik;

   Abstract : The interaction between the solar wind and Earth’s magnetic field creates the Earth’s bow shock. It is an ideal region for space probes like MMS, THEMIS or Clusters to study the collisionless shock phenomenon in space plasma. READ MORE

6. 5. Unspecific interactions in different batch variations of agarose based base matrices at different NaCl concentrations.

   University essay from Karlstads universitet/Institutionen för ingenjörs- och kemivetenskaper (from 2013)

   Author : Kejvan Ghofranpanah; [2022]
   Keywords : Lysozyme; hydrophobicity; size exclusion chromatography; NaCl concentrations; isocratic elution; Lysozym; hydrofobicitet; size exclusion chromatography; NaCl-koncentrationer; isokratisk eluering;

   Abstract : Size exclusion chromatography (SEC) separates molecules based on their actual size rather than their molecular weight. This indicates that the smaller a molecule is, the longer it will be held in the column since it can penetrate the pores more effectively than a bigger molecule, resulting in a longer retention time, whereas the larger molecule has a shorter retention time.
