2. 1. Surface Integrity Characterization of Gears with respect to Running-in

   Author : Dinesh Mallipeddi; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; micropitting; surface asperities; running-in; surface roughness; residual stresses; Gears; surface chemistry;

   Abstract : A gearbox with gears of different sizes is part of a vehicle transmission system that plays an important part in transmitting the engine power to the wheels. The efficient energy transmission highly relies on the performance of gears. Together, the mesh efficiency and durability determines the gear performance. READ MORE

5. 3. Lithium titanate as anode material in lithium-ion batteries : -A surface study

   Author : Tim Nordh; Kristina Edström; Daniel Brandell; Carl Tengstedt; Carla Puglia; Uppsala universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; titanate battery anode SEI; Kemi med inriktning mot materialkemi; Chemistry with specialization in Materials Chemistry;

   Abstract : The ever increasing awareness of the environment and sustainability drives research to find new solutions in every part of society. In the transport sector, this has led to a goal of replacing the internal combustion engine (ICE) with an electrical engine that can be powered by renewable electricity. READ MORE

6. 4. Electric Fields for Surface Design and Chemical Analysis

   Author : Christian Ulrich; Fredrik Björefors; Ingemar Lundström; Tautgirdas Ruzgas; Linköpings universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Electric fields; Surface design; Chemical analysis; Bipolar electrodes; Impedance spectroscopy; Electrochemistry; Elektrokemi; Chemical physics; Kemisk fysik; Physical chemistry; Fysikalisk kemi; Surface and colloid chemistry; Yt- och kolloidkemi;

   Abstract : This thesis deals with the use of electric fields for evaluation and control of chemical systems. An electric field can result in the flow of charge across an interface between a metal and a solution, by means of chemical reactions. This interplay between electricity and chemistry, i.e. READ MORE

7. 5. Surface Engineering Approach to Frictional Optimization

   Author : Staffan Johansson; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Piston Ring; Lubrication; Rig testing; Tribometer; Design of Experiments; Cylinder Liner; Friction; Oil consumption; Diesel Engine; Wear;

   Abstract : Reducing emissions is a top priority within heavy duty diesel engine development and research. The power cylinder system is a main contributor to emissions and accounts for about 50% of the total frictional losses found in the engine, so is important to optimize. READ MORE
