2. 1. Bark Biorefinery : Isolation, Characterization and Application

   Author : Isabella Kwan; Monica Ek; Åsa Emmer; Anette Larsson; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Sustainability; bark; biorefinery; Norway spruce; nanocellulose; Pickering emulsion; organosolv; extraction; lignin; Hållbarhet; bark; bioraffinaderi; gran; nanocellulosa; Pickering emulsioner; organosolv; extraktion; lignin; Fiber- och polymervetenskap; Fibre and Polymer Science;

   Abstract : To fulfill the United Nations’ 17 sustainable development goals, there is a need to transition from a petroleum-based society toward a more sustainable one which requires new solutions and the production of materials, chemicals, and energy from renewable resources. Using side-stream products from industries to produce value-added products will be economically beneficial. READ MORE

4. 2. Cellulose-based Nanocomposites – The Relationship between Structure and Properties

   Author : Shiyu Geng; Kristiina Oksman; Laurent Matuana; Luleå tekniska universitet; []

   Abstract : Nanocellulose materials extracted from various types of biomass have recently attracted significant attention. Due to their remarkable mechanical properties, large surface area and biodegradability, they can be promising reinforcements in nanocomposites. READ MORE

5. 3. Plasmonics with a Twist: from Single Particles to Metasurfaces

   Author : Robin Ogier; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; colloidal lithography; localized surface plasmons; circularly polarized light; metsurfaces; nanofabrication; chirality; optical trapping;

   Abstract : Nanophotonics deals with how electromagnetic fields can be confined and squeezed to orders of dimensions below the light wavelength. Plasmonics, one of the fields of nanophotonics, study collective free electron oscillations driven by light in metallic nanostructures and interfaces. READ MORE

6. 4. Formulation and characterization of W/O nano-dispersions for bioactive delivery applications

   Author : Maria D. Chatzidaki; Aris Xenakis; Bert van Bavel; Werner Kunz; Örebro universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; nano-dispersions; encapsulation; food; DLS; EPR; Cryo-TEM; SAXS; pH-stat; digestion; antioxidants; gastric lipase; pancreatic lipase; Kemi; Chemistry;

   Abstract : The main objective of this study was the formulation of food-grade water-in-oil (W/O) nano-dispersions based mainly on medium or long-chain triglycerides. Two types of dispersions were formulated and structurally compared, namely emulsions and microemulsions. READ MORE

7. 5. Water-based Flexographic Printing on Polymer-coated Board

   Author : Maria Rentzhog; Mark Rutland; Joseph Aspler; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Surface and colloid chemistry; Yt- och kolloidkemi;

   Abstract : This doctoral thesis comprises three studies dealing with water-based flexography on polymer-coated boards, which have been presented in the five papers included at the end of the thesis. The first study (covered in three papers) presents results from characterisation of a matrix of water-based inks with respect to their rheology, surface tension, wetting, and fulltone printing performance on PE-coated board.
