  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. Moisture Transport in PA6

    University essay from Lunds universitet/Hållfasthetslära; Lunds universitet/Institutionen för byggvetenskaper

    Author : Emanuel Markström; [2022]
    Keywords : Technology and Engineering;

    Abstract : Polyamide 6 (PA6) is known to absorb water from its environment due to its chemical structure. The water absorption leads to changes in the mechanical properties as well as an increase in volume (swelling) of the polyamide. READ MORE

  3. 3. On-chip characterization of hydroxyapatite with different topography

    University essay from Uppsala universitet/Institutionen för materialvetenskap

    Author : Maja Grape; [2022]
    Keywords : biomaterials; calcium-deficient hydroxyapatite; microfluidic systems;

    Abstract : Biomaterials are defined as non-viable materials whose functions strives to interact with biological systems, this makes biomaterials suitable for medical devices and applications. Biomaterials biological properties must be thoroughly investigated and evaluated in order to be approved for clinical usage. READ MORE

  4. 4. Define optimum process conditions to produce CO2 adsorbents from pur materials

    University essay from Högskolan i Borås/Akademin för textil, teknik och ekonomi

    Author : Daniel Pantzar; Anton Coates; [2022]
    Keywords : Carbon capture and storage; Adsorbent; Chemical activation;

    Abstract : The Carbon Capture and Storage method has been acknowledged for the capabilities of reducing up to 20% CO2 emissions. Development of porous carbon materials prepared from polyurethane foam adsorbent were investigated for capture of CO2. In this thesis work, the carbon material was chemically activated through the direct and indirect methods. READ MORE

  5. 5. Development of alkaline earth metal-based, metal-organic frameworks for greenhouse gas sorption

    University essay from Uppsala universitet/Institutionen för materialvetenskap

    Author : Ali Maghsoodpoor; [2022]
    Keywords : Metal-organic Framework; gas sorption;

    Abstract : Metal-organic frameworks (MOFs) constructed from metal atoms connected by organic linkers have received extensive attention for greenhouse gas separation in the past decades. Moreover, their large surface area makes them a promising candidate as adsorbents for gas sorption. READ MORE
