  2. 11. Multiscale modeling of atomic transport phenomena in ferritic steels

    Author : Luca Messina; Pär Olsson; Nils Sandberg; Pål Efsing; Pascal Bellon; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; diffusion; impurities; iron; metals; kinetic Monte Carlo; ab initio; mean field; defects; embrittlement; reactor pressure vessel; neural networks; Fysik; Physics;

    Abstract : Defect-driven transport of impurities plays a key role in the microstructure evolution of alloys, and has a great impact on the mechanical properties at the macroscopic scale. This phenomenon is greatly enhanced in irradiated materials because of the large amount of radiation-induced crystal defects (vacancies and interstitials). READ MORE

  5. 13. Flow processing and gel formation for producing biopolymer drops with functional shapes and diffusion properties

    Author : Bernhard Walther; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; drop deformation; 4-roll mill; biopolymer; agarose; shear; Kappa-carrageenan; elongation; microstructure; flow processing; drop-shaping; rheology; poly ethyleneglycol ; diffusion; gelatine; NMR; gel formation; TEM; flow channel;

    Abstract : This thesis focuses on the development of novel processes which combine flow-induced drop deformation and simultaneous temperature-induced gel formation in order to create shaped biopolymer drops. The drops are functional in terms of rheology and diffusion properties, factors strongly influencing the consistency of food products and flavour or drug release. READ MORE

  6. 14. Towards Radio-Environment Aware IoT Networks : Wireless Coexistence Methods for Low-complexity Devices

    Author : Simone Grimaldi; Mikael Gidlund; Aamir Mahmood; Tingting Zhang; Georgios Z. Papadopoulos; Mittuniversitetet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; IoT; Industrial IoT; Interference; Machine Learning; Wireless Coexistence; Wireless Networks;

    Abstract : Wireless technologies for short-range communication play a central role in the massive diffusion of the Internet of Things (IoT) paradigm. Such communication solutions rely extensively on the availability of unlicensed spectrum in the form of bands for industrial, scientific, and medical (ISM) applications. READ MORE

  7. 15. Exploring the Role of Business Models in Large-Scale Diffusion of Solar Photovoltaics - A study of demand-side solar firms in Sweden

    Author : Amanda Bankel; Chalmers tekniska högskola; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; firm; innovation; sustainability; Sweden; photovoltaic; business model; diffusion; solar; system; policy;

    Abstract : A rapid and large-scale diffusion of renewable energy technologies, like solar photovoltaics (PV), is crucial to slow down climate change. Research on technology diffusion explains that the rate and scale at which a new technology diffuses in society is influenced by the actors, networks, and institutions that make up its innovation system.
