2. 1. Oxidized Cladophora nanocellulose derivatives : Functionalization towards biocompatible materials

   Author : Igor Rocha; Jonas Lindh; Natalia Ferraz; Albert Mihranyan; Maria Strömme; Eva Malmström Jonsson; Uppsala universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cladophora nanocellulose; TEMPO oxidation; periodate oxidation; sulfonation; cellulose beads; surface properties; biomaterials; cell studies; hemocompatibility;

   Abstract : Nanocellulose is a promising candidate for biomedical applications because of its enhanced mechanical properties, increased surface area and greater porosity compared to bulk cellulose.This thesis investigates the functionalization of Cladophora nanocellulose and evaluates the influence of these modifications on physicochemical properties and biocompatibility of the material.

4. 2. Effects of warming on the green alga Cladophora glomerata : Ecological and genetic responses

   Author : Jenny Zie; Pauline Snoeijs; Mats Grahn; Anna Godhe; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; AFLP; Baltic Sea; Cladophora glomerata; climate change; community ecology; genome scan; global warming; selection; Marine Ecology; marin ekologi;

   Abstract : Since the beginning of the 20th century, average global surface temperature has increased ~0.7 °C and the current scenarios predict that it will continue to rise additional 2-4 °C during the 21st century. READ MORE

5. 3. Mille-feuille Filter : A Non-woven Nano-cellulose Based Virus Removal Filter for Bioprocessing

   Author : Simon Gustafsson; Albert Mihranyan; Jonas Lindh; Kurt Brorson; Uppsala universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; virus filtration; mille-feuille; downstream; nanocellulose; protein throughput; protein recovery; LRV; MVM; Cladophora; non-woven filter;

   Abstract : Virus removal filters, produced from synthetic surface-modified polymers or regenerated cellulose by phase inversion, are vital to the production of therapeutic proteins such as monoclonal antibodies and plasma proteins. Use of these filters is also one of the most expensive purification steps in the downstream processing of proteins due to high sales price and being limited to a single use. READ MORE

6. 4. Cladophora Cellulose-based Separators for Lithium Batteries

   Author : Ruijun Pan; Leif Nyholm; Maria Strömme; Jonas Lindh; Zhaohui Wang; Martin Winter; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Cellulose; Separator; Paper making; Lithium-ion battery; Lithium-metal battery; Functionalization.; Kemi med inriktning mot materialkemi; Chemistry with specialization in Materials Chemistry;

   Abstract : The development of lithium-ion batteries (LIBs) has been focused on exploring and improving the electrode materials and electrolytes in the past decades. An indispensable component, the separator, is however not studied as extensively. In general, a separator has two functions, i.e. READ MORE

7. 5. Development of Cellulose-Based, Nanostructured, Conductive Paper for Biomolecular Extraction and Energy Storage Applications

   Author : Aamir Razaq; Albert Mihranyan; Srømme Maria; Leif Nyholm; Johan Bobacka; Uppsala universitet; []
   Keywords : Polypyrrole; Cladophora cellulose; Conductive paper; Electrochemically controlled ion-exchange; DNA extraction; Paper-based energy storage devices; Chopped Carbon fibers; Teknisk fysik med inriktning mot nanoteknologi och funktionella material; Engineering Science with specialization in Nanotechnology and Functional Materials;

   Abstract : Conductive paper materials consisting of conductive polymers and cellulose are promising for high-tech applications (energy storage and biosciences) due to outstanding aspects of environmental friendliness, mechanical flexibility, electrical conductivity and efficient electroactive behavior. Recently, a conductive composite paper material was developed by covering the individual nanofibers of cellulose from the green algae Cladophora with a polypyrrole (PPy) layer. READ MORE
