  2. 1. Open-Framework Germanates : Synthesis, Structure, and Characterization

    Author : Andrew Kentaro Inge; Xiaodong Zou; Anthony Cheetham; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Open-framework; zeolites; germanates; porous materials; crystallography; hydrothermal synthesis; crystal structure; Structural Chemistry; strukturkemi;

    Abstract : Novel open-framework germanates and open low-dimensional structures were synthesized and characterized. Their crystal structures were solved by single crystal X-ray diffraction or X-ray powder diffraction combined with other techniques. READ MORE

  4. 2. Ensembles and Open Quantum Systems in Polaritonic Chemistry

    Author : Eric Davidsson; Markus Kowalewski; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Polaritonic Chemistry; Optical Cavities; Open Quantum Systems; Quantum Simulations; teoretisk fysik; Theoretical Physics;

    Abstract : Optical cavities—where spatial confinement can focus electromagnetic excitations—are able to couple matter to light with enough strength that the behaviour of the combined system is best understood in terms of polaritonic states; mixtures of excitations in both light and matter. This polaritonic regime provides a novel approach for modification and control of chemical reactions, and lately, experimental advancements are realising this potential. READ MORE

  5. 3. Ensembles and Open Quantum Systems in Polaritonic Chemistry

    Author : Eric Davidsson; Markus Kowalewski; Gerrit Groenhof; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Polaritonic Chemistry; Open Quantum Systems; Cavity QED; The Jaynes-Cummings Model; Optical Cavities; Computational Quantum Dynamics; Theoretical Physics; teoretisk fysik;

    Abstract : Optical cavities are structures where excitations in the electromagnetic field (photons of light) are confined and generally long-lived. The spatial confinement will enhance interactions with any matter systems in the cavity, such that the behaviour of a combined system is best understood in terms of polaritonic states; mixtures of excitations in both light and matter.

  6. 4. Gating and modulation mechanism of voltage gated sodium channels

    Author : Koushik Choudhury; Lucie Delemotte; Erik Lindahl; Philip Biggin; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Voltage gated sodium channels; Molecular dynamics simulation; π-helix; open state; Biologisk fysik; Biological Physics;

    Abstract : Voltage-gated sodium channels (Nav channels) play an essential role in nerve impulse conduction in excitable cells. Thus, these channels are involved in several neurological and muscular disorders. Understanding their mechanism of functioning  is essential for designing drugs targeting them. READ MORE

  7. 5. Dispersion Engineering : Negative Refraction and Designed Surface Plasmons in Periodic Structures

    Author : Zhichao Ruan; Min Qiu; Henri Benisty; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; photonic crystal; dispersion property; negative refraction; surface plasmon polariton; designed surface plasmon; negative index material; layer-KKR method; finite-difference time-domain method; plane wave method; subwavelength imaging; open cavity; enhanced transmission; slowing light; Photonics; Fotonik;

    Abstract : The dispersion property of periodic structures is a hot research topic in the last decade. By exploiting dispersion properties, one can manipulate the propagation of electromagnetic waves, and produce effects that do not exist in conventional materials. READ MORE
