  1. 1. Towards the detection of single photons in the mid-infrared

    University essay from KTH/Tillämpad fysik

    Author : Bruno Lopez; [2021]
    Keywords : mid-infrared; single-photon; superconducting; nanowire; nanotechnology; quantum technologies; imaging; mitten av infraröd; enfoton; supraledande; nanotråd; nanoteknik; kvantteknologi; avbildning;

    Abstract : In this project, the fabrication of single-photon detectors based on superconducting nanowires is presented, with great focus on extending their operation range to the mid infrared. In particular, Niobium Titanium Nitride (NbTiN) and Molybdenum Silicide (MoSi), superconducting materials with different properties, are presented, studied and used as fabrication platforms.

  3. 2. Photodegradation of macroplastics to microplastics : A laboratory study on common litter found in urban areas

    University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Author : Jonathan Svedin; [2020]
    Keywords : ;

    Abstract : During the last 60 years the plastic production has increased more than 190 times and plasticpollution both at sea and land is a growing issue. Every year millions of tons of plastic waste fromland reaches the oceans, but the land-based sources are diffuse. READ MORE

  4. 3. Synthesis and Characterization of some Photo-CORM and Photosensitizers

    University essay from Lunds universitet/Kemiska institutionen

    Author : Joachim Björklund; [2019]
    Keywords : Inorganic Chemistry; Bioinorganic Chemistry; CORM; Photo-CORM; Photosensitizers; Synthesis; Characterization; Oorganisk kemi; Chemistry;

    Abstract : It is well known that Carbon monoxide is a toxic and hazardous gas, but during recent years it has been proven that using a controlled concentration, carbon monoxide can in fact be used as a therapeutic agent, and can contribute to decrease malaria, treat cardiovascular and lung diseases and potentially even treat cancer, among other things. The main problem in using carbon monoxide directly is the fact that it is not trivial to control the volume of gas inhaled, compromising its use as a therapeutic agent. READ MORE

  5. 4. Study on ongoing subsidence in Uppsala City using Sentinel-1 radar data

    University essay from Högskolan i Gävle/Samhällsbyggnad

    Author : Jonas Fryksten; [2019]
    Keywords : InSAR; PSI; precise leveling; validation; clay;

    Abstract : Many cities in Sweden are partly located on clay and because of that, some urban city centres are undergoing significant subsidence. To measure subsidence in cities, precise leveling has been the traditional technique, but the interest for the Persistent Scatter InSAR (PSI) technique has increased in the last years, in this application.

  6. 5. Non-invasive ultrasound measurements of vascular impedance

    University essay from Lunds universitet/Avdelningen för Biomedicinsk teknik

    Author : Roger Larsson; [2018]
    Keywords : Ultrasound; ultrafast ultrasound imaging; vascular impedance; pulse wave velocity; motion tracking; Technology and Engineering;

    Abstract : Despite its introduction in the early 1950´s, vascular impedance has yet to be applied in clinical use to predict early stages of cardiovascular disease (CVD). It is defined as the ratio between blood pressure and flow and describes the opposition to blood flow within the cardiovascular system. READ MORE
