1. 1. Organic reactions in self-organized surfactant systems

   Författare :Fredrik Currie; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; organic synthesis; kinetics; micelle; regioselectivity; microemulsion;

   Sammanfattning : The aim of this work has been to investigate how microemulsions and micellar systems can be used as reaction media to overcome reactant incompatibility, enhance reaction rates and especially to control product composition, i.e., introducing regioselectivity, in organic synthesis.

5. 4. Phenomenological modelling of sensory integration phenomena using self-organized feature maps

   Författare :Tamas Jantvik; Wlodzislaw Duch; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Industriell elektronik; Industrial Electronics;

   Sammanfattning : The main contribution of the work presented herein is a method of transferring information from one lattice of artificial neural units to another. The essence of the present method consists of four parts: (1) the wrapping of the artificial neural lattice into a module that given an input to this lattice outputs normalized coordinates for the location of peak activity and the magnitude of the activity at that location; (2) the inter-module exchange of information being carried out by using the coordinates of the neuron that respond the strongest to the input given to the artificial neural lattice; (3) the concept of the transformation map which re-maps normalized coordinates from one module's output space on another's; and (4) fusion carried out by summation of activity fields induced by artificial neural lattices.

7. 5. Femtosecond Laser Microfabrication of Glasses and 2D Materials for Photonics and Energy Storage

   Författare :Po-Han Huang; Frank Niklaus; Göran Stemme; Kristinn Gylfason; Yves Bellouard; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Femtosecond laser; 3D printing; self-organized nanogratings; micromachining; silica glass; silicon-rich glass; hydrogen silsesquioxane; photonic microdevice; microsupercapacitor; 2D materials; direct ink writing; Electrical Engineering; Elektro- och systemteknik;

   Sammanfattning : Femtosecond laser-based fabrication technologies have seen rapid developments in the past decades, thanks to the capability of femtosecond lasers to induce localized multiphoton absorption in materials. Multiphoton absorption can result in various material modifications that can be leveraged for additive and subtractive manufacturing. LÄS MER
