2. 1. Housing Aquaporins in Nanostructured Glass

   Author : Simon Isaksson; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Membrane protein; Water; Interface; Aquaporin; Silica; Formation; Silicification;

   Abstract : Proteins are a group of biomolecules that perform versatile tasks, which in many cases are essential for life. The magnitude of their importance is perhaps expressed by the word protein itself, coined by the Swedish chemist Jöns Jacob Berzelius in the summer of 1838. READ MORE

4. 2. Additive manufacturing of fused silica glass

   Author : Pawel Maniewski; Michael Fokine; Fredrik Laurell; Daniel Milanese; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; laser cladding; 3d printing; additive manufacturing; glass; fused silica; laser; scattering; silica; Optik och fotonik; Optics and Photonics; Teknisk materialvetenskap; Materials Science and Engineering;

   Abstract : Additive Manufacturing, of both metals and polymers, has seen rapid development in recent years, whereas the progress in glass has been rather slow. Today, glass can be considered the last frontier without a specialized 3D printing method available. READ MORE

5. 3. Mechanical and Environmental Durability of High Performance Bio-based Composites

   Author : Newsha Doroudgarian; Egidija Rainosalo; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Polymera konstruktionsmaterial; Polymeric Composite Materials;

   Abstract : This study is an initial step within the on-going project on development of high performance bio-based composites with improved mechanical (fatigue) and environmental (elevated humidity and temperature) durability. In the presented thesis the performance of cellulosic fibers (flax and regenerated cellulose), bio-based resins (Tribest, EpoBioX, Palapreg, and Envirez) and their composites under exposure to elevated humidity has been studied.

6. 4. Modification of Float Glass Surfaces by Ion Exchange

   Author : Stefan Karlsson; Bo Jonson; Helmut Schaeffer; Linnéuniversitetet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Ion exchange; float glass; surface modification; surface colour; flexural strength; Glasteknologi; Glass Technology;

   Abstract : Glass is a common material in each person’s life, e.g. drinking vessels, windows, displays, insulation and optical fibres. By modifying the glass surface it is possible to change the performance of the entire glass object, generally known as Surface Engineering. READ MORE

7. 5. Bright Lights: Innovative Micro- and Nano-Patterning for Sensing and Tissue Engineering

   Author : Alessandro Enrico; Göran Stemme; Frank Niklaus; Anna Herland; Jürgen Brugger; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Micro-electromechanical systems MEMS ; nanotechnology; nanowires; microfabrication; tissue engineering; crack-lithography; direct writing; femtosecond lasers; two-photon polymerization; 3D micromachining; cavitation molding; scalable optical patterning; 2D materials; surface structuring; bacterial-surface interaction.; Electrical Engineering; Elektro- och systemteknik;

   Abstract : Light is the primary source of energy on our planet and has been a significant driver in the evolution of human society and technology. Light finds applications in two-dimensional (2D) photolithography and three-dimensional (3D) printing, where a pattern is transferred to a material of interest by ultraviolet (UV) light exposure, and in laser scribing and cutting, where high power lasers are used to pattern the surface of objects or cut through the bulk of the material of interest.
