  2. 6. Terahertz radiation as a pump and probe for studying low frequency vibrations in proteins

    Author : Ida Lundholm; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Terahertz radiation; Protein dynamics;

    Abstract : Many functionally important structural changes in proteins proceed along the direction of their lowest frequency vibrations. These vibrations correspond to picosecond collective dynamics. Establishing the fundamental relationship between these vibrations and protein function remains a challenge within biophysics.

  4. 7. Graphene FET terahertz detectors on flexible substrates

    Author : Xinxin Yang; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; sensors; THz detectors; flexible electronics; 2D materials; Graphene; field-effect transistors; plastic substrates.;

    Abstract : Terahertz (THz) science and technology have developed rapidly over the past decades, extending the THz application areas from spectroscopy and earth and space sciences to communications, biomedicine and security sensing. Many of these emerging applications require shape-conforming, light-weight and low-cost detectors rather than existing solid-state detection technology. READ MORE

    Abstract : Light-induced interactions in biomolecules are strongly varying over different model systems. Most amino acids and proteins absorb ultraviolet light, but only a few with specialised chromophores or fluorophores, are able to absorb light in the visible spectrum. READ MORE

  7. 10. Polymer-Based Micromachining for Scalable and Cost-Effective Fabrication of Gap Waveguide Devices Beyond 100 GHz

    Author : Sadia Farjana; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Dry film photoresist; Terahertz frequency; Injection molding; MEMS; mmWave; Gap waveguide; Antenna; Waveguide; Polymer microfabrication;

    Abstract : The terahertz (THz) frequency bands have gained attention over the past few years due to the growing number of applications in fields like communication, healthcare, imaging, and spectroscopy. Above 100 GHz transmission line losses become dominating, and waveguides are typically used for transmission. READ MORE
