  1. 26. Mass Transport via Thermoplasmonics

    Författare :Steven Jones; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : When a metallic nanoparticle is illuminated with light under resonant conditions, the free electron gas oscillates in such a way that substantial amplification of the local electric field amplitude is achieved – this is known as a plasmonic resonance. This resonance enhances both the optical scattering as well as absorption. LÄS MER

  3. 27. The electrophysiological response of medial preoptic neurons to hypoxia and development of a system for patch-clamp measurement with full oxygen control

    Författare :Nazanin Bitaraf; Ronnie Lundström; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Medical Engineering for Healthcare; Medicinsk teknik för hälsovård;

    Sammanfattning : A stroke is caused by interruption of the blood supply to the brain. Yearly 15 million people around the globe endure a stroke and the costs and suffering for the people involved and the society are immense. LÄS MER

  4. 28. Microfluidics and AI for single-cell microbiology

    Författare :Praneeth Karempudi; Johan Elf; Yoav Shechtman; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Microfluidics; Artificial intelligence; Deep learning; Single-cell microbiology; Biology with specialization in Molecular Biotechnology; Biologi med inriktning mot molekylär bioteknik;

    Sammanfattning : Most of the biological sciences deal with understanding the relationships between phenotypes and the underlying molecular mechanisms of organisms. This thesis is an engineering, computational, and experimental exercise in expanding the scope and scale of phenotype-genotype mapping techniques in single-cell microbiology using microscopy, microfluidics, and image processing.

  5. 29. On the importance of nanometer structures for implant incorporation in bone tissue

    Författare :Lory Melin Svanborg; Malmö högskola; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : Introduction Replacing lost teeth with dental implants is today a reliable treatment method associated with good long-term clinical results. Different surface modifications alter the surface topography at micro- and nanometer level of resolution as well as chemical properties, which have shown to be of importance for osseointegration.

  7. 30. Metabolic communication between individual yeast cells

    Författare :Martin Mojica Benavides; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Metabolic synchronization; Single-cell; glycolytic oscillations; synchronization waves;

    Sammanfattning : With the recent progress in sensitive cell manipulation and microfabrication techniques, glycolytic oscillations in yeast have been observed at a single-cell level. It was shown that individually, oscillating cells could entrain their phases by periodic external perturbations. LÄS MER
