Method development for the analysis of polydimethylsiloxane in bio-oils
(2021)
The chemistry of wood is quite complex. Wood consists of several components, such as cellulose, hemicelluloses, lignin, and extractives, which are all important during pulping. The components are either used as the final ...
Analys av växtsteroler med gaskromatografi och FT-NIR-spektroskopi
(2021)
Målet med denna pro gradu-avhandling var att jämföra och evaluera fyra olika gaskromatografiska metoder för analys av växtsteroler. Det har presenterats flera metoder i litteraturen, men de flesta tillämpas på analys av ...
Analysis of major ions, stable water isotopes and black carbon in the upper part of Belucha ice core, Siberian Altai
(2021)
There are many different paleoarchives, e.g. sediments, ice cores, tree-rings, speleothems and corals. This master’s thesis focuses on the information receivable from ice cores. Well preserved information of past precipitation ...
Novel design of a flow-through potentiometric sensing device
(2021)
An innovative design of planar electrodes for flow-through potentiometric sensing devices is presented in this thesis. A planar and concentric potassium solid-contact ion-selective electrode (K+-SCISE) has been designed. ...
Synthesis of an Electroconductive Hydrogel in 3D Printing Formulation for Tissue Engineering
(2021)
The progress made in tissue engineering to treat damage caused by disease and traumatic injury has been accelerated by innovations in bioengineering over the last few decades. The strategy of repairing and revitalizing ...
Functionality of solid-contact ISEs with physically damaged ion-selective membranes : a comparison between potentiometric, coulometric and amperometric methods
(2021)
In this thesis, a novel ion-to-electron signal transduction method was applied for checking the functionality of chloride and potassium solid-contact ISEs with physically damaged ion-selective membranes (ISMs). The ...
Polymer and electrocatalytic membranes for improved selectivity of glucose biosensor
(2021)
In the last decades research in the sphere of biosensors concentrates on the invention of wearable devices that would give an opportunity to patients to perform necessary analysis in vivo painlessly, easily, and effectively. ...
Determination of benzoate in cranberry and lingonberry using solid-contact ion-selective electrode; comparison with ion chromatography
(2021)
The purpose of this thesis was to develop the solid-contact ion-selective electrodes and to characterize them as benzoate-selective electrodes. The developed electrodes were then applied for the determination of benzoate ...
Exfoliering av grafit i cellulosa nanokristaller (CNC) och framställning av elektriskt ledande grafen-CNC-kompositfilmer
(2021)
I denna pro gradu-avhandling har grafen-nanocellulosa(CNC)-kompositmaterial tillverkats av högkoncentrerade grafen-CNC-dispersioner genom sprejning med airbrushpenna på glassubstrat. Metoden som använts för att framställa ...
