  2. 1. 3D Electron Diffraction : Application and Development towards High-quality Structure Determination

    Author : Yunchen Wang; Wei Wan; Xiaodong Zou; Junliang Sun; Mauro Gemmi; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; three-dimensional electron diffraction; structure determination; rotation electron diffraction; Inorganic Chemistry; oorganisk kemi;

    Abstract : Electron crystallography has been proven to be effective for structure determination of nano- and micron-sized crystals. In the past few years, 3D electron diffraction (3DED) techniques were used for the structure solution of various types of complex structures such as zeolites, metal-organic frameworks (MOF) and pharmaceutical compounds.

    Author : Bei Wang; Klas Hjort; Zhigang Wu; Magnus Berggren; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; laser patterning; sacrificial mask; liquid metal; strain sensor; skin movement; masking; shrink film; 3D conformal masking; liquid metal particles; soft electronics; stretchable electronics; compliant electronics; skin-like electronics; epidermal electronics; micro-heater; particle sintering; enteroendocrine cells; localized ectopic expression; wettability; flexography printing; conformal transfer printing; hydro printing; plant physiology; drosophila;

    Abstract : Skin-like electronics could provide a soft and gentle contact with living beings for perceiving and delivering the information of pressure, strain, temperature with higher spatial resolution and sensitivity than our skin, without disturbing the user. Gallium-based liquid metal (LM) is an excellent material for soft and stretchable skin-like devices, since it has high electrical and thermal conductivity, flowability, and self-healable capability.
