  2. 1. Infrared Neural Modulation: Photothermal Effects on Cortex Neurons Using Infrared Laser Heating

    Author : Qingling Xia; Tobias Nyberg; Björn Granseth; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; neural modulation; infrared laser; in - vitro experiment; multi - electrode arrays MEA ; heating model; temperature; neural networks; infrared neural inhibition INI ; hyperexcitation;

    Abstract : It would be of great value to have a precise and non-damaging neuromodulation technique in the field of basic neuroscience research and for clinical treatment of neurological diseases. Infrared neural modulation (INM) is a new modulation modality developed in the last decade, which uses pulsed or continues infrared (IR) light with a wavelength of 1200 to 2200 nm to directly alter neural signals.

  4. 2. III-V Nanowire-based Infrared Photodetectors : Design, Fabrication and Characterization

    Author : Vishal Jain; Fasta tillståndets fysik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; nanowire; infrared; photodetector; APD; thermal imaging; telecommunication; fabrication; InP; InAsP; Fysicumarkivet A:2016:Jain;

    Abstract : Semiconductors are the backbone of almost every electrical or optical component, one of them being photodetectors. Photodetectors are used in many applications such as digital cameras or solar panels. They can also be designed to detect the omnipresent infrared radiation, discovered in 1800, which is invisible to human eye. READ MORE

  5. 3. Intermolecular interactions in hydrogen bonded 1:1 molecular complexes. A matrix isolation study

    Author : Anders Engdahl; Biokemi och Strukturbiologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; infrared laser irradiation; dimethyl ether; water dimer; hydrogen chloride; formamide; acetone; formic acid; ammonia; water; intermolecular; matrix isolation; FIR; FTIR; infrared; isomerisation; ab initio; Physical chemistry; Fysikalisk kemi;

    Abstract : A number of matrix isolated binary hydrogen bonded complexes with water as one of the components have been investigated with FTIR in the mid and far infrared regions. Water has been found to be the hydrogen bond donor in complexes with water, ammonia, dimethyl ether and acetone. READ MORE

  6. 4. Structure-Specific Vibrational Modes of Isolated Biomolecules Studied with Mid- and Far-Infrared Laser Spectroscopy

    Author : Vasyl Yatsyna; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; far-infrared gas-phase spectroscopy; conformers; vibrational anharmonicity; infrared multiple photon dissociation; peptide structure; folded and extended peptides; hydrogen bonding;

    Abstract : Biomolecular structure elucidation is crucial for our detailed understanding of various biological processes, since there is an intimate relationship between the biomolecular function and structure. In this respect, isolated biomolecules, despite being outside of their natural environment, are perfect model systems for in-depth studies of various fundamental interactions that govern the formation of biomolecular structure.

  7. 5. Extrasolar Kuiper and asteroid belts Modelling far-infrared dust emission

    Author : Joachim Wiegert; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Stars: binaries - Stars: circumstellar matter - Infrared: stars - Infrared: planetary systems - Submillimeter: stars;

    Abstract : The first detections of circumstellar dust emission were announced in the mid 1980s. Direct observations of the edge-on disc of beta Pictoris provided evidence that the dust was part of possible planetary systems. About a decade later, in 1995, the first confirmed extrasolar planet around a main sequence star (51 Pegasi b) was announced. READ MORE
