1. 1. Degradation of Microplastic Residuals in Water by Visible Light Photocatalysis

   University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

   Author : Tajkia Syeed Tofa; [2018]
   Keywords : Microplastics; Low density Polyethylene LDPE ; Heterogeneous photocatalytic degradation; Zinc oxide nanorods; Visible light.;

   Abstract : Microplastic (MP) pollution has recently been recognized as a threat to the biosphere including humans due to its widespread distribution, persistent nature and infinitesimal size. This study focused on the solid phase degradation of microplastic residues (particularly low density polyethylene, LDPE) in water through heterogeneous photocatalysis process by designed photocatalysts of zinc oxide nanorods (ZnO NRs) and platinum nanoparticles deposited on zincoxide nanorods (Pt NPs-ZnO NRs) under visible light irradiation.

3. 2. Bark assortments for tall oil production

   University essay from SLU/Department of Forest Biomaterials and Technology (from 131204)

   Author : Patrik Isacsson; [2016]
   Keywords : tall oil; bark; extractives; lipophilic compounds; CTO; TOFA; TOR; fatty acids; resin acids; rosin; Norway spruce; Scots pine; Picea abies; Pinus sylvestris;

   Abstract : Fatty and resin acids in bark residues from forest industries can be used to produce high-value green chemicals. Of the assortments investigated, the bark of spruce pulpwood held the highest amount of these compounds with an average yield of 0.9 kg per cubic meter of wood. READ MORE
