  1. 1. Investigation of Adsorption and Retention of Charged Compounds In RPLC

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

    Author : Emma Fryxelius; [2022]
    Keywords : adsorption; adsorption isotherm; charged compounds; promethazine hydrochloride; propranolol hydrochloride; mixed-mode; retention; RPLC;

    Abstract : The adsorption isotherm of two weak bases, Promethazine hydrochloride and Propranolol hydrochloride, were determined with isocratic reversed-phase liquid chromatography, with a 60 w% methanol in 20 mM sodium acetate buffer pH 4 as the mobile phase, and calculated by the elution by characteristic points method. The data obtained from the method were then fitted into the Langmuir isotherm and the electrostatically modified Langmuir. READ MORE

  2. 2. The Changing Character of Mars’ Bow Shock

    University essay from Umeå universitet/Institutionen för fysik

    Author : Sara Östman; [2021]
    Keywords : Bow shock; Space plasma physics; Mars;

    Abstract : The aim of the project is to investigate the characteristics and causes of two different types of bow shocks at Mars. We define Type 1 as an undefined, drawn out ramp, and Type 2 as a shorter duration ramp that has clearer characteristics and behaves more like a step increase in the magnetic field. READ MORE

  4. 4. Adhesive modelling in multi-material structures : Evaluating the strength and fatigue life of adhesive joints

    University essay from Linköpings universitet/Mekanik och hållfasthetslära

    Author : Nitin Narayanaswamy; [2020]
    Keywords : Adhesive Joints Strength Calculation J Integral Method Energy Release Rate Theory Crack Finite Element Analysis Multi Material Structures Automotive;

    Abstract : Advancements in material science and manufacturing techniques are enabling the use of lightweight metal alloys and polymer composites in several combinations and shapes for producing more efficient and lightweight structures for automotive applications without compromising strength, stiffness and/or durability. When evaluating the strength of the structure, the joints are of importance. READ MORE

  5. 5. Virtual Material Testing of Adhesive Joints

    University essay from KTH/Hållfasthetslära

    Author : Vinit Jethalal Nagda; [2020]
    Keywords : ;

    Abstract : The automotive industry has shown an increasing interest in adhesive bonding for mixed-material joining. Modern design methods are critically dependent on accurate material models and data for numerical methods to enable the simulation of a design prototype early in the design process. READ MORE
