1. Cellulose nanocrystals functionalized cellulose acetate electrospun membranes for adsorption and separation of nanosized particles
University essay from Luleå tekniska universitet/MaterialvetenskapAbstract : 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

2. Formulation of nanoemulsions stabilized by cellulose nanocrystals
University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)Abstract : Cellulose nanocrystals (CNCs) are bio-based nanoparticles with the ability to stabilize oil and water emulsions thanks to their intermediate wettability and nanometric size. These and other types of particle-stabilized emulsions, commonly referred to as Pickering emulsions, are of great academic and industrial interest due to their superior stability against drop coalescence compared to classical surfactant-stabilized emulsions.

3. Evaluation of cellulose nanocrystal alignment in oriented electrospun fibers
University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematikAbstract : Electrospinning is a fiber production method that has gained a special attention due to the simple setup and potential for the industry scale up to produce nanoregime polymer fibers. However, electrospun fibers have relatively poor mechanical properties, which could be improved by introducing reinforcing agents. READ MORE

4. Production of regenerated nanocomposite fibers based on cellulose and their use in all-cellulose composites
University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematikAbstract : Biobased all-cellulose composites (ACCs), in which the matrix and the reinforcement are made out of the same material, have gained a noticeable increased attention in recent years. Their successful application would solve the commonly faced challenges with natural fiber composites regarding their chemical antipathy between the hydrophilic fiber and the usually hydrophobic polymer matrix, while still keeping the advantages of being environmental friendly.

5. Nanoparticle loaded hydrogels as a pathway for enzyme controlled drug release in ophthalmic applications
University essay from Uppsala universitet/Nanoteknologi och funktionella materialAbstract : The aim of this study was to develop nanoparticle loaded hydrogel based contact lenses that could be used for ocular drug delivery. Two potential contact lens platforms for controlled ophthalmic drug delivery was thus developed by incorporating chitosan-poly(acrylic acid) nanoparticles into polyvinyl alcohol (PVA) hydrogels and nanoparticles together with cellulose nanocrystals (CNC) in PVA.
