2. 1. Biomimetic Deposition of Hydroxyapatite on Titanium Implant Materials

   Author : Carl Lindahl; Håkan Engqvist; Martin Andersson; Uppsala universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materialvetenskap; Materials Science;

   Abstract : The clinical success of a bone-anchored implant is controlled by many factors such as implant shape, chemical composition, mechanical and surface properties. The surface properties (e.g. READ MORE

   Abstract : The intercellular material in bone is a nanocomposite of aligned “hard” inorganics—calcium phosphate (CaP) platelets embedded in the long-range ordered “soft” organic collagen matrix. This elaborate structural arrangement redeems the weaknesses of the individual components (being soft protein or brittle mineral) and gives bone its excellent mechanical properties for the protection and support of our bodies.

5. 3. Tailored layer-by-layer films of nanofibrillated cellulose

   Author : Erdem Karabulut; Lars Wågberg; Lennart Piculell; Eva Blomberg; KTH; []
   Keywords : layer-by-layer assembly; nanofibrillated cellulose; thin film; surface adsorption; polyelectrolytes;

   Abstract : The preparation of multifunctional films, coatings and membranes from natural, sustainable and low-cost raw materials has attracted considerable interest during the last decade. In this respect, cellulose-based products possess a great promise for research and industry due both to the availability of large amounts of material in nature and to the preparation of new classes of nano-sized and well-characterized building-blocks of cellulose from trees or annual plants.

6. 4. Translational Tumor Drug Delivery : Doxorubicin formulation performance, intracellular uptake and molecular diffusion

   Author : Oliver Degerstedt; Hans Lennernäs; Erik Sjögren; Per Hansson; Jessica Rosenholm; Uppsala universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; doxorubicin; drug diffusion; cellular uptake; drug delivery; PBPK modelling; hepatocellular carcinoma; emulsion; IC50; Farmaceutisk vetenskap; Pharmaceutical Science;

   Abstract : Globally, hepatocellular carcinoma (HCC) is the most common form of liver cancer and a leading cause of cancer death. One important risk factor is liver cirrhosis and the disease progression is characterized by deposition of extracellular matrix proteins that form a fibrous network, which increases liver stiffness and may limit the effectiveness of different treatment strategies.

7. 5. Advanced Nanostructured Transition Metal Oxide Semiconductors for Solar Energy Applications

   Author : Pedram Ghamgosar; Alberto Vomiero; Nils Almqvist; Federica Rigoni; Mauro Salvatore Epifani; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Metal Oxide; Photovoltaic; Semiconductors; Self-powered photodetectors; Photoelectrochemical cell; Solar fuel; Water splitting; Experimentell fysik; Experimental Physics;

   Abstract : Increasing energy consumption and its environmental impacts make it necessary to look for alternative energy sources. Solar energy as huge energy source that can cover the terms sustainability is considered as a favorable alternative. READ MORE
