2. 1. Where did the ink go? : The effect of liquid absorption on ink distribution in flexography

   Author : Sofia Thorman; Li Yang; Magnus Lestelius; Martti Toivakka; Karlstads universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; flexographic printing; print mottle; ink trapping; absorbency; absorption non-uniformity; water-interference mottle; Chemical Engineering; Kemiteknik;

   Abstract : The appearance of a print is affected by the individual ink layers. If the ink is unevenly distributed on the substrate it lowers the quality. This thesis puts focus on how the liquid absorbency of a coated substrate impacts on the ink distribution in flexographic printing. READ MORE

4. 2. Study the Influence of Quantum Interference on the Electrical Conductance and Thermoelectric Properties of Molecular Junctions : Synthesis and Thermoelectricity

   Author : Hailiang Xu; NanoLund: Centre for Nanoscience; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Molecular junctions; charge transport; electronic conductance; thermoelectricity; destructive quantum interference; acetylene molecules; Sonogashira coupling; Ti-mediated transformation; porphyrin; MacDonald [2 2] approach; [3 1] method;

   Abstract : This thesis mainly describes our efforts towards the study of the quantum interference of electronic conductance and thermoelectric properties in molecular junctions. Chapter 1 introduces the concepts of the charge transport in single-molecule junctions, include the electrical conductivity and thermopower which are the main parameters to assess the efficiency of the single-molecule junctions.

5. 3. Quantum Force in Wigner Space

   Author : Huaqing Li; Göteborgs universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

   Abstract : In this thesis, I will present effective methods to study quantum dynamics using trajec- tories. Our methods are based on a method named the Classical Wigner model which starts with a quantum initial condition and generates trajectories which are propagated in time using a classical force.

6. 4. Interfacial Adhesion Failure : Impact on print-coating surface defects

   Author : Hajer Kamal Alm; Lars Wågberg; Göran Ström; Janet Preston; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Ink-paper coating adhesion; offset printing; calcium carbonate pigments; polyacrylate; dispersant; print mottle; surface chemistry; hygroscopy of surfaces; coating structure; print quality; water interference mottle; Fiber- och polymervetenskap; Fibre and Polymer Science;

   Abstract : The aim of this work was to develop a solid knowledge on formulation effects controlling offset ink-paper coating adhesion and to identify key factors of the coating and printing process affecting it. Focus lay on comprehending the impact of pigment dispersant on ink-paper coating adhesion and ultimately on the print quality of offset prints. READ MORE

7. 5. Materials Design for the Improvement of SiC Field Effect Gas Sensor performance in High Temperature Process Control applications

   Author : Lida Khajavizadeh; Mike Andersson; Fredrik Eriksson; Krisztian Kordas; Linköpings universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Abstract : Following growing concerns about the effect these last decades of accelerating energy consumption, escalating use of natural (not the least fossil) resources, and waste generation has had on earth’s climate, human health, and the environment, industry is facing mounting pressure to increase the energy-, resource-, and cost-efficiency of both processes and products while drastically reducing pollutant emissions. In response, industry is, besides increasing their utilization of renewable energy and introducing new bio-based products, taking advantage of the rapid development in 5G technology and associated wireless interconnectivity to move towards full automation of production processes and facilities.
