1. 21. A NOx sensor for high-temperature applications based on SiC

   University essay from Tillämpad Fysik

   Author : Johan Midbjer; [2010]
   Keywords : chemical Sensor; NOx; CoO; MgO; Kemisk sensor; NOx; CoO; MgO;

   Abstract : A new NOx sensor for high-temperature applications has been developed and thouroghly characterised. The sensor layers are a mixed oxide of CoO, MgO and MgO2 deposited by thermal evaporation with a porous platinum gate on top, deposited by thermal evaporation or sputtering. READ MORE

3. 22. A microtechnology-based sensor system for deepwater analysis from a miniaturized submersible

   University essay from Ångström Space Technology Centre (ÅSTC)

   Author : Katarina Smedfors; [2010]
   Keywords : CTD; MEMS; microtechnology; sensors; thin film metallization; microelectrodes;

   Abstract : The aim of this master thesis has been to design, and partly manufacture and evaluate, a highly miniaturized, on-chip conductivity-temperature-depth (CTD) sensor system for deepwater analysis also including electrodes for pH and chloride ion concentration measurements. The microtechnology-based sensor system will be a vital instrument onboard the Deeper Access, Deeper Understanding submersible, which will be small enough for deployment through bore holes into the subglacial lakes of Antarctica.

4. 23. Investigation of Metal-assisted Si Etching for Fabrication of Nanoimprint Lithography Stamps

   University essay from Sektionen för Informationsvetenskap, Data– och Elektroteknik (IDE)

   Author : Ksenia Anokhina; [2010]
   Keywords : metal-assisted chemical etching; nanoimprint stamps;

   Abstract : This diploma thesis deals with the investigation of the metal-assisted catalytic etching (MaCE) of Si. One of the main goals is to study fabrication of stamps for nanoimprint lithography using MaCE. Formation of nanoporous silicon (PSi), Si nanowires (SiNWs) and three-dimensional nanostructures in Si by MaCE is demonstrated. READ MORE

5. 24. Development of Free-Standing Interference Films for Paper and Packaging Applications

   University essay from Institutionen för fysik, kemi och biologi

   Author : Johan Holmqvist; [2008]
   Keywords : layer-by-layer; interference thin film; free-standing; moisture sensor; polyelectrolyte; surface self-assembly; silanization;

   Abstract : The newfound capability of creating moisture sensitive interference multilayered thin films (MLTFs) comprising microfibrillated cellulose and polymers has not previously been possible to implement on surfaces other than silicon wafer strips. Being able to incorporate interference MLTFs on fibre-based materials would introduce the possibility for new applications within authentication, sensing and customer attraction for the paper and packaging industry.

6. 25. An Optimisation Model for Sea Port Equipment Configuration

   University essay from Blekinge Tekniska Högskola/Avdelningen för för interaktion och systemdesign

   Author : Gideon Mbiydzenyuy; [2007]
   Keywords : modelling; optimization; handling equipments; containers;

   Abstract : Today, freight volumes on roads have gone up to a level that there is a need for alternative transport modes. Short Sea Shipping (SSS) is one alternative with a potential that can help reduce the high traffic on roads. READ MORE
