1. 6. Design of telechelic oligo-(caprolactone-co-dioxanone) as photocurable macromonomers for degradable gels

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

   Author : Tran Tam Nguyen; [2020]
   Keywords : macromonomers; ring-opening co-oligomerization; telechelic co-oligomers; polymer; organocatalyst; makromonomerer; ringöppning samoligomerisering; telekelisk samoligomer; organisk katalysator;

   Abstract : Three-dimensional (3D) printing has an important role for fabrication of degradable scaffoldsfor soft tissue regeneration. Among the 3D printing techniques, photopolymerization-based 3Dprinting is one of fastest growing, offering environmental benefits and high precision of 3Dobjects. READ MORE

3. 7. Optical Characterization of Lignin Nanoparticles

   University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

   Author : Kristoffer Linder; [2020]
   Keywords : lignin; nanoparticles; nanoparticle; optical characterization; optical properties; surface plasmon resonance;

   Abstract : Lignin is one of the main components of wood and plants that acts as a kind of glue providing mechanical strength. It is a main polymer component composed from three phenolic structures, i.e. p-hydroxyphenyl (H), guaiacyl (G) and syringyl (S) units. READ MORE

4. 8. Inductively-Coupled Plasma Etching for Nanoimprint Si-masters

   University essay from Lunds universitet/Fasta tillståndets fysik; Lunds universitet/Fysiska institutionen

   Author : Oskar Boström; [2019]
   Keywords : NIL; Semiconductor; EBL; SEM; ICP-RIE; Fluorine Etching; Physics; Technology and Engineering;

   Abstract : In the last decades, engineers have been pushing semiconductor technology towards fabricating ever smaller devices, and will eventually pass the lower limit of currently commonplace optical lithographic techniques. New techniques have been developed, such as nanoimprint lithography. READ MORE

5. 9. Adsorption of micropollutants in wastewater using pulverized activate carbon - The influence of organic matter content and characteristics

   University essay from Lunds universitet/Miljövetenskaplig utbildning

   Author : Anna Nicola Messinger; [2019]
   Keywords : Pulverised Activated carbon; PAC; UVA254; Wastewater treatment; Micropollutants; Activated carbon; Earth and Environmental Sciences;

   Abstract : Wastewater is one of the biggest emission sources of organic micropollutants to the aquatic environment. Due to the negative effects of micropollutants on the receiving waters, advanced treatment steps are needed to reduce these emissions. Activated carbon is one promising approach. READ MORE

6. 10. Spatial resolution threshold in layers and red jungle fowls : are there differences due to light intensity or light spectra?

   University essay from SLU/Dept. of Animal Environment and Health

   Author : Pauline Annerstedt; [2018]
   Keywords : spatial resolution threshold; layer; red jungle fowls; visual acuity;

   Abstract : The domestic fowl (Gallus gallus domesticus) originates from the forests in South-east Asia. It may be correct to assume that the visual system of the domestic fowl is still adapted to light that is filtered through the green forest canopy. READ MORE
