  1. 1. Aurora detector : Affordable device for detection of optical aurora

    Kandidat-uppsats, Linnéuniversitetet/Institutionen för fysik och elektroteknik (IFE)

    Författare :hans Alin; [2022]
    Nyckelord :Aurora; Detection;

    Sammanfattning : Aurora is a light phenomenon in the night sky that fascinates many people. This project has aimed to develop a detector that can send alerts to users and tell whether or not there is an aurora event. Many want to see the aurora, but not as many want to stay up all night to have the chance to see them. LÄS MER

  3. 2. Optical Detector for Microfluidics

    Magister-uppsats, Högskolan i Halmstad/Akademin för informationsteknologi

    Författare :Carlos Gómez Jiménez; Jaime Gómez Jiménez; [2022]
    Nyckelord :Serial crystallography; Microfluidic device; Optical detector; Particle counting;

    Sammanfattning : This project arose from the need to filter the sampled data and eliminate non-useful information in Serial Crystallography in Microfluidic Device (MFD)by using a portable optical detector placed around the channel. By testing sixteen different configurations, always using an LED as a source and a photodiode as a light sensor, changes in the channel due to the passage of air bubbles were detected. LÄS MER

  4. 3. An Inexpensive Alpha Spectrometer Based on a p-i-n Photodiode : Making Advanced Particle Detectors From Common Commercial Components

    Kandidat-uppsats, Uppsala universitet/Institutionen för materialvetenskap

    Författare :Elias Arnqvist; [2022]
    Nyckelord :Alpha spectroscopy; alpha particle; particle detector; radiation detector; p-i-n diode; PIN diode; photodiode;

    Sammanfattning : The purpose of this project was to design, construct, and evaluate an alpha spectrometer based on an inexpensive p-i-n photodiode as a radiation detector. The BPX-61 p-i-n photodiode was selected and calculated to have a 93 µm wide sensitive volume at 25 V reverse bias. LÄS MER

  5. 4. Developing complementary supercritical fluid chromatographic methods for a high throughput purification process

    Master-uppsats, Karlstads universitet

    Författare :Alma Söderström; [2022]
    Nyckelord :Supercritical Fluid Chromatography; Pharmaceutical Industry; Column screening; Green chemistry; Superkritisk vätskekromotografi; Läkemedelsindustri; Kolonn set; Grön kemi;

    Sammanfattning : Supercritical fluid chromatography (SFC) is an expanding chromatographic technique that is part of the evolving field of green chemistry due to its short run times and use of non-toxic solvents in combination with recycled CO2. The use of a suitable column is essential for separation science in general and there is a wide variety of SFC compatible columns available on the market. LÄS MER

  7. 5. Achieving Optimal Alignments of IR Source and Detector in Waveguide Based Gas Sensor

    Uppsats för yrkesexamina på grundnivå, KTH/Medicinteknik och hälsosystem

    Författare :Sefik Güler; Agbai Randolph Agwu; [2020]
    Nyckelord :Non-dispersive infrared technology; microelectromechanical systems; infrared light; electromagnetic spectrum; gas sensor; light emitting diode; photodiode detector; Icke-dispersiv infraröd teknologi; mikroelektromekaniska system; infrarött ljus; elektromagnetiskt spektrum; gassensor; lysdiod; fotodioddetektor;

    Sammanfattning : I takt med att tekniken för mikroelektromekaniska system utvecklas uppkommer det nya områden för tillämpning. Ett område är inom gassensorer där icke-dispersiv infraröd strålning används genom att mäta absorptionen hos olika gaser för att bestämma mängden av en specifik gas i luften. LÄS MER
