2. 1. Mixed Substrate Computation. Sensor Based Artificial Cognition for Architectural Design and Modification

   Author : Stig Anton Nielsen; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES;

   Abstract : A mutual relationship exists between activities and their physical environment. Change of circumstances in the built environment cause change of activities, and vice versa, change of activities cause changes of physical environment. READ MORE

4. 2. Ink-paper interaction : a study in ink-jet color reproduction

   Author : Li Yang; Linköpings universitet; []
   Keywords : ;

   Abstract : An ink jet printing system consists of three fundamental parts: inks, printing engine, and substrates. Inks are materials creating color by selectively absorbing and scattering the visible illumination light. The printer acts as an ink distributor that governs the ink application. READ MORE

5. 3. Electronic and Geometric Structure of Phthalocyanines on Metals

   Author : Masumeh-Nina Shariati; Maria Novella Piancastelli; Carla Puglia; Kajsa Uvdal; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; monolayer; multilayer; metal-free phthalocyanine; metal phthalocyanine; interaction; intermolecular; adsorbate-substrate; XPS; XAS; STM; DFT; alkali; metallization;

   Abstract : Adsorption of monolayers and multilayers of metal-free and metal phthalocyanines molecules on metal surfaces has been investigated using complementary microscopic and synchrotron-based spectroscopic techniques. It was observed by STM measurements that at monolayer coverage the adsorption direction of the metal-free phthalocyanine molecules with respect to the gold surface vary as a function of temperature, i.

6. 4. On the influence of surface roughness on rolling contact forces

   Author : Oskar Lundberg; Ines Lopez Arteaga; Leif Kari; Matthias Kröger; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Rolling contact; Surface roughness; Contact forces; Contact modelling; Friction; Road; Asphalt; Substrate; Test-rig; Sliding; Stick–slip; Tyre; Rubber; Tread-block; Wheel–rail interaction; Vehicle and Maritime Engineering; Farkostteknik;

   Abstract : Road vehicle tyres, railway wheels and ball bearings all generate rolling contact forces which are transferred within a finite area of contact between the rolling element and the substrate. Either it is visible or not for the human eye, a certain degree of roughness is always present on the contacting surfaces and it influences the generation of both vertical and lateral contactforces.

7. 5. Effect of Substrate on Bottom-Up Fabrication and Electronic Properties of Graphene Nanoribbons

   Author : Konstantin Simonov; Olof Karis; Nils Mårtensson; Alexei Preobrajenski; Alessandro Baraldi; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; graphene nanoribbons; bottom-up; substrate; metal contact; electronic structure; electron doping; PES; ARPES; NEXAFS; STM; Physics with spec. in Atomic; Molecular and Condensed Matter Physics; Fysik med inriktning mot atom- molekyl- och kondenserande materiens fysik;

   Abstract : Taking into account the technological demand for the controlled preparation of atomically precise graphene nanoribbons (GNRs) with well-defined properties, the present thesis is focused on the investigation of the role of the underlying metal substrate in the process of building GNRs using bottom-up strategy and on the changes in the electronic structure of GNRs induced by the GNR-metal interaction. The combination of surface sensitive synchrotron-radiation-based spectroscopic techniques and scanning tunneling microscopy with in situ sample preparation allowed to trace evolution of the structural and electronic properties of the investigated systems.
