1. 11. Cellulose nanocrystals functionalized cellulose acetate electrospun membranes for adsorption and separation of nanosized particles

   University essay from Luleå tekniska universitet/Materialvetenskap

   Author : José Ignacio Del Río De Vicente; [2021]
   Keywords : Electrospinning; Cellulose Nanocrystals; Filtration; Adsorption; Cellulose Acetate Fibers;

   Abstract : Filtration and separation technologies remain as one of the biggest challenges humanity currently faces. The separation of different elements such as bacteria, viruses, heavy metals, particles, and chemical agents require the development of multifunctional membranes. READ MORE

3. 12. Surface functionalization of nonwoven polypropylene with BTCA polycarboxylic acid in supercritical carbon dioxide medium

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

   Author : Md Fahad Khan; [2021]
   Keywords : Nonwoven polypropylene; Supercritical carbon dioxide; Surface functionalization; 1; 2; 3; 4- Butanetetracarboxylic acid; Impregnation; Environmentfriendly; Hydrophilicity;

   Abstract : Nonwoven polypropylene has been utilized broadly in various hygienic and medical textile applications because of its excellent mechanical properties, chemical resistance, and minimal expense contrast with other synthetic polymers. However, the insufficiency of surface tethering groups, including adhesion, wettability, and hydrophilicity, some applications are not convenient on nonwoven polypropylene surfaces such as dyeing, printing, attachment of antibacterial and bioactive agents.

4. 13. Hur förändringsarbeten påverkar den psykosociala hälsan – ett exempel från skogsbranschen

   University essay from SLU/School for Forest Management

   Author : Linus Lindberg; [2020]
   Keywords : förändring; psykologi; skogsbruk;

   Abstract : Det svenska skogsbruket sysselsätter idag cirka två procent av Sveriges arbetande befolkning. Från skogen kommer förnyelsebar råvara som i framtiden sannolikt kommer att bli ännu mer eftertraktad. I skogen finns många intressenter så kraven är höga från stat, markägare, miljörörelse och kunder. READ MORE

5. 14. Biosensor based on immobilized amine transaminase for detection of amphetamine

   University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

   Author : Clara Öh; [2020]
   Keywords : amine transaminases ATA ; enzyme immobilization; biosensor; covalent immobilization; ionic immobilization; amphetamine; histidine-tagged enzyme; Poly methyl methacrylate PMMA ;

   Abstract : Amine transaminases (ATA) catalyse the transfer of an amino group from one molecule and replaces a ketone or aldehyde with the amino group, the amino group on the amino-donor is replaced with a ketone or aldehyde. This enzyme, ATA from Chromobacterium violaceum, has previously been used to catalyse the reaction involving amphetamine, therefore, it might be possible to use this enzyme to convert amphetamine and the product absorbs in the UV spectrum and can therefore be measured spectrophotometrically.

6. 15. Poly(p-terphenyl piperidinium) as anion exchange membranes. Synthesis and evaluation of properties

   University essay from Lunds universitet/Centrum för analys och syntes

   Author : Hugo Selling; [2020]
   Keywords : Fuel cells; Alkaline exchange membrane fuel cells; Anion exchange membrane fuel cells; Polymer technology; Polymerteknologi; Chemistry; Technology and Engineering;

   Abstract : Alkaline exchange membrane fuel cells (AEMFC) is an interesting and attractive alternative to proton exchange membrane fuel cells (PEMFC) due to the potential use of non-precious catalysts which can reduce the overall cost of the fuel cell. An important component of the AEMFC is the anion conducting membrane. READ MORE
