  2. 1. Fiber Optic Sensors for Monitoring of Lithium- and Sodium-ion Batteries

    Author : Jonas Hedman; Fredrik Björefors; Daniel Brandell; Alexis Grimaud; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Evanescent waves; Fiber optic evanescent wave sensors; Fiber optic sensors; Graphite; Hard carbon; LiBOB; Lithium iron phosphate; Lithium manganese oxide; Lithium plating; Lithium-ion batteries; Prussian white; Sodium plating; Sodium-ion batteries; Kemi med inriktning mot materialkemi; Chemistry with specialization in Materials Chemistry;

    Abstract : Rechargeable batteries, particularly lithium-ion batteries, have rapidly evolved since their introduction and now dominate the market, owing primarily to their high energy and power densities. With growing demand for high-performance batteries in portable electronics and electric vehicles, the need for safe, efficient, and reliable batteries is crucial. READ MORE

  4. 2. Fiber-optic sensors for blood flow and respiration rate measurements

    Author : Erik Stenow; Linköpings universitet; []
    Keywords : MEDICINE; MEDICIN;

    Abstract : Optical fibers and fiber-optic sensors have in the last century been subjects for a great interest especially in industry and communication but also in medicine. Optical fibers are used in endoscopes and as light guides for laser surgery. READ MORE

  5. 3. Digital Twins for Asset Management of Structures

    Author : Vanessa Saback; Björn Täljsten; Rasmus Rempling; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Digital Twins; BIM; Asset Management; Common Data Environment; Finite Element Modelling; Fiber Optic Sensors; Byggkonstruktion; Structural Engineering;

    Abstract : This thesis deals with asset management of structures through Building Information Modelling (BIM) and Digital Twins.Background: Current inspection and management processes for civil structures are time-consuming and can even be inaccurate. There is an increasingly high potential to improve these processes through recent advances in technology. READ MORE

  6. 4. Dendron decorated chromophores for optical power limiting applications

    Author : Robert Vestberg; KTH; []
    Keywords : Life sciences and physical sciences; polymer chemistry; optics physics; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP;

    Abstract : The need for protection of eyes and electro-optic sensors from powerful lasers has increased the need for new and better optical power limiting (OPL) materials that can protect against laser light. In this study the synthesis and characterization of dendron-coated OPL chromophores (porphyrins, thiophenes, and platinum(II) acetylides) are discussed. READ MORE

  7. 5. Laser Remote Sensing for Environmental Monitoring

    Author : Zuguang Guan; Atomfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; fiber-optic sensor; gas analysis; food-package monitoring; multiple scattering; zero-background measurement; diode laser spectroscopy; ecological study; aerosol; trace pollutant; LIDAR; laser-induced fluorescence; DIAL; methane monitoring;

    Abstract : This thesis studies the techniques of laser remote sensing and their applications in environmental monitoring, as documented in several published papers. The environment where the human being live is degrading with an accelerating speed. READ MORE
