1. 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
Kandidat-uppsats, Karlstads universitet/Institutionen för ingenjörs- och kemivetenskaper (from 2013)Sammanfattning : 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.

2. Water quality improvement of highway runoff by the filter material D-Rainclean : A five-month field trial
Master-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknikSammanfattning : Highway runoff and its pollutants are of growing concern. These pollutants require treatment as their concentration often are increased. A common removal method is the use of sedimentation ponds that removes particulates through gravity. LÄS MER
3. Application of electrodes with redox mechanisms for the desalination of water
Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)Sammanfattning : Capacitive deionization is a promising technology for purification and desalination of brackish water with great advantages over current technologies due to its low operating cost and high-water recovery ratio. Most of the system studied relies on the adsorption/desorption capacity of activated carbon electrodes due to its high surface area. LÄS MER
4. Techno-economic Assessment of Carbon Capture from Low Concentration Streams
Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)Sammanfattning : Investments in carbon capture from industrial emissions have been on the rise in recent years, having reached over $200 million in 2021 as compared to 2015’s $13 million. The Paris Agreement, signed by 196 parties globally in 2015, is purported to be the primary driver for this, with its ambitious goal of limiting global surface temperature rise to 1. LÄS MER
5. A Quantum Chemical Investigation of Chemical Vapour Deposition of Fe using Ferrocene and Plasma Electrons
Master-uppsats, Linköpings universitet/KemiSammanfattning : Thin films provide a remarkable asset, as depositing a thin surface layer can completely alter a material’s characteristics and provide new, inexpensive, and valuable properties. In 2020, a new Chemical Vapour Deposition (CVD) approach was developed at Linköping University, using plasma electrons as reducing agents for the deposition of metallic thin films. LÄS MER
