2. 1. Towards Unconventional Applications of Wire Bonding

   Author : Stephan Schröder; Frank Niklaus; Michael Mayer; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Micro-electromechanical systems MEMS ; heterogeneous 3D integration; wire bonding; wire integration; transfer wafer bonding; nondispersive infrared gas sensing; low-stress packaging; shape memory alloy SMA ; infrared IR emitter; through silicon via TSV ; ethanol sensing; nitric oxide gas sensing; wafer-level; chip-level; Kanthal; nickel chromium NiCr ; Electrical Engineering; Elektro- och systemteknik;

   Abstract : This thesis presents novel heterogeneous integration approaches of wire materials to fabricated and package MEMS devices by exploring unconventional applications of wire bonding technology. Wire bonding, traditionally endemic in the realm of device packaging to establish electrical die-to-package interconnections, is an attractive back-end technology, offering promising features, such as high throughput, flexibility and placement accuracy.

4. 2. Hydrogen production from fossil fuels with carbon dioxide capture, using chemical-looping technologies

   Author : Magnus Rydén; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; chemical-looping combustion; carbon capture and storage; partial oxidation; Chemical-looping reforming; synthesis gas; hydrogen; steam reforming;

   Abstract : Carbon capture and storage have been receiving increasing interest lately, mainly as an option to reduce CO2 emissions from the power sector. The concept could be adapted for production of H2 as well, which would provide a carbon free energy carrier that could be used for example as transportation fuel. READ MORE

5. 3. On the effects of Streptococcal NAD+-glycohydrolase and Streptolysin O on macrophages

   Author : Elsa Westerlund; Värd-patogeninteraktioner; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Innate immunity; macrophage; Streptococcus pyogenes; IL-1beta; Nad -glycohydrolase;

   Abstract : SummaryThe human pathogen Streptococcus pyogenes (GAS) causes both superficial infections, such as strep throat, and invasive infections, such as necrotizing fasciitis, and is responsible for about half a million deaths each year. The number of GAS infections have increased since the 1980’s, due to the emergence of a M1T1 strain that has become widely disseminated. READ MORE

6. 4. On Combustion in the CNG-Diesel Dual Fuel Engine

   Author : Fredrik Königsson; Hans-Erik Ångström; Helmut Eichlseder; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Machine Design; Maskinkonstruktion;

   Abstract : Currently there is a large interest in alternative transport fuels. There are two underlying reasons for this interest: the desire to decrease the environmental impact of transports and the need to compensate for the declining availability of petroleum. In the light of both these factors, the CNG-diesel dual fuelengine is an attractive concept. READ MORE

7. 5. Decarbonization in Carbon-Intensive Industries - An Assessment Framework for Enhanced Early-Stage Identification of Optimal Decarbonization Pathways

   Author : Tharun Roshan Kumar; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Carbon-intensive industries; Industrial decarbonization; Process integration; Cost estimation; CO2 Capture; Exergy and Pinch analyses; Process modeling;

   Abstract : Carbon-intensive industries currently account for a quarter of global annual CO2 emissions. Achieving mandated climate targets necessitates the rapid implementation of decarbonization technologies in these industries. Such deployments typically involve substantial upfront investments amidst technical, economic, and policy uncertainties. READ MORE
