2. 1. Nanoplasmonic Alloy Hydrogen Sensors

   Author : Ferry Nugroho; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; indirect nanoplasmonic sensing; plasmonic sensors; hydrogen sensors; polymers; fiber optics; nanofabrication; localized surface plasmon resonance; alloy nanoparticles; carbon capture and storage; sensors; palladium;

   Abstract : The hydrogen economy proposes hydrogen gas as the main energy carrier thanks to its high energy density and the possibility to produce it in a sustainable way without CO2 emission. However, the wide flammability range of hydrogen-air mixtures dictates that hydrogen sensors will be a mandatory accessory to any appliance or vehicle fueled by hydrogen. READ MORE

   Abstract : Sensors are omnipresent in our daily life. They are used in many applications ranging from the touch screen in our smartphones to more critical contexts such as pollution monitoring. READ MORE

5. 3. Evaluation of biomedical microwave sensors : Microwave sensors as muscle quality discriminators in laboratory and pilot clinical trial settings

   Author : Viktor Mattsson; Robin Augustine; Mauricio Perez; Roger Karlsson; Ayca Özcelikkale; Uppsala universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Microwave sensors; Sarcopenia; Muscle quality assessment; Biomedical applications; Tissue dielectric properties; Data-driven modelling; Clinical trials; EM Simulations; Phantom experiments; Teknisk fysik med inriktning mot elektronik; Engineering Science with specialization in Electronics;

   Abstract : In this thesis the primary focus is on the evaluation of biomedical microwave sensor to be used in the muscle analyzer system. Lower muscle quality is one indicator that a patient can have sarcopenia. Therefore the muscle analyzer system can be a tool used in screening for sarcopenia. READ MORE

6. 4. Hydrogel-based pH-sensors : Development and characterisation of optical and electrical pH sensors based on stimuli-responsive hydrogels

   Author : Krister Hammarling; Hans-Erik Nilsson; Magnus Engholm; Henrik Andersson; Guido Perrone; Mittuniversitetet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hydrogel; fiber optics; printed electronics; pH; sensor;

   Abstract : The ability to measure the chemical parameter pH is of high importance in many areas. With new government regulations and evolving markets, there is a strong motivation for improving such measurements and conducting research on new types of pH sensors and sensor materials. READ MORE

7. 5. Development and Use of Optical Sensors in Modern Analytical Chemistry

   Author : Aron Hakonen; Göteborgs universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Optical sensors; Optodes; Imaging sensors; Fluorescence; pH; Ammonium; Sensing; Nanoparticle enhancement; Plasmonics;

   Abstract : A successful long-term high resolution imaging experiment in marine sediments was performed (17 days within the sample; Paper I). The time correlated calibration procedure was evolved to include parametric sigmoidal and logarithmic functions to provide three of the best performing (optical) pH sensors available up to date (Papers II, III and IV), precision of these sensors were in the 0.
