2. 1. Amyloid Proteins in Neurodegenerative Disease – Role of Extrinsic Modifiers

   Author : Nima Sasanian; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Abstract : ABSTRACT Self-assembly of disease-associated proteins into fibrillar homopolymers, so-called “amyloid fibrils” is a pathological hallmark of several debilitating human disorders, including Alzheimer’s disease (AD) and Parkinson’s disease (PD). AD and PD are associated with the formation of amyloid fibrils from the proteins amyloid-β (Aβ) and α-syn (α-syn), in the extracellular and intracellular space, respectively. READ MORE

   Abstract : Due to climate change and plastic pollution, there is an increasing demand for bio-based materials with similar properties to those of common plastics yet biodegradable. In this respect, cellulose is a strong candidate that is already being refined on a large industrial scale, but the properties differ significantly from those of common plastics in terms of shapeability and water-resilience.

   Abstract : Nanocellulose has received considerable interest during the last decade because it is renewable and biodegradable, and has excellent mechanical properties, nanoscale dimensions and wide functionalization possibilities. It is considered to be a unique and versatile platform on which new functional materials can be based. READ MORE

6. 4. Organic electronics on micro and nano fibers : from e-textiles to biomolecular nanoelectronics

   Author : Mahiar Hamedi; Olle Inganäs; George Malliaras; Linköpings universitet; []
   Keywords : NATURAL SCIENCES; NATURVETENSKAP;

   Abstract : Research in the field of conjugated polymers (CPs) has led to the emergence of a number of interesting research areas and commercial applications, including solar cells, flexible displays, printed electronics, biosensors, e-textiles and more.Some of the advantages of organic electronics materials, as compared to their inorganic counterparts, include high elasticity, and mechanical flexibility, which allows for a natural integration of CPs into fabrics, making them ideal for e-texile.

   Abstract : Cancer represents a significant global public health challenge and ranks as the second mostcommon cause of death in the United States. The onset of cancer entails an initial phasewhere cells lose their polarity and disconnect from the normal basement membrane, allowingthem to form distinct three-dimensional (3D) configurations that interact with adjacent cellsand the surrounding microenvironment.
