16. New Materials for Gas Sensitive Field-Effect Device Studies
Sammanfattning : Gas sensor control is potentially one of the most important techniques of tomorrow for the environment. All over the world cars are preferred for transportation, and accordingly the number of cars increases, unfortunately, together with pollutants. Boilers and powerplants are other sources of pollutants to the environment. LÄS MER
17. Nano- and Micro-sized Molecularly Imprinted Polymer Materials for Analytical Application
Sammanfattning : Specific molecular recognition materials are important in analytical applications. It has been a longstanding dream for scientific explorers to realise a versatile method to generate materials that can recognize biological and chemical substance of interests. LÄS MER
18. Multifunctional Waveguide Grating Couplers for Integrated Optics
Sammanfattning : This thesis describes a novel waveguide component in integrated optics called a multifunctional grating coupler. It couples light in or out of optical waveguides and provides additional optical functions such as beam splitting, arbitrary focusing, polarization sensing, and wavelength separation (wavelength division demultiplexing).

19. Molecular Adsorption on Self Assembled Monolayers studied by Surface Acoustic Waves and Infrared Spectroscopy
Sammanfattning : Chemical sensors based on the selective absorption of gas/vapors in polymer layers rely on molecular interactions. Details of the mechanisms involved can be obtained by studying the adsorption on well defined model organic surfaces. LÄS MER
20. Photoplethysmography in multiparameter monitoring of cardiorespiratory function
Sammanfattning : Photoplethysmography (PPG) is an optical, non-invasive method to assess tissue blood volume/perfusion. When measured on human skin, the PPG signal includes both cardiac synchronous variations (AC) and respiratory induced intensity variations (RIIV). LÄS MER
