Privacy, Trust and Interaction in the Internet of Things

Abstract. This workshop addresses topics of increasing importance in the emerging area of the Internet of Things (IoT): privacy, trust and related interaction concepts. The aim of the workshop is to bring together experts from different areas to cover the complexity of the questions involved and to provide a forum for developing new ideas on how to address the major challenges in the field considering both a scientific and an industrial viewpoint. The workshop targets to identify pressing questions and to develop a research agenda for trusted and privacy-respecting computing in the IoT. Special attention within the workshop is given on whether and how experiences with privacy and trust from related areas can be applied to the IoT, where existing conceptualizations need to be extended or modified and where radically new concepts are required. The Internet of Things (IoT) is an umbrella term covering a number of different base technologies aimed at linking physical objects and their virtual representation with the goal to utilize this link for improved service and interaction concepts [3]. The IoT approach combines concepts and paradigms informed by Ambient Intelligence, Ubiquitou

Correlation between experimental and DFT calculations of photocatalytic and optical properties of La0.8Nd0.1Sr0.1MnO3 perovskite: degradation efficiency of methyl orange dye under visible-irradiated conditions

La0.8Nd0.1Sr0.1MnO3 perovskite was synthesized using the citrate gel method. The crystal structure was studied by X-ray diffraction. The Rietveld refinement reveals a single R-3C rhombohedral structure. The morphological properties were investigated by a scanning electron microscopy, connected to an energy-dispersive X-ray detector for mapping and elements composition, showing a sponge-like structure behavior of agglomerated particles. The band gap energy and the optical properties were studied theoretically by Density-Functional Theory (DFT) calculations. It showed that La0.8Nd0.1Sr0.1MnO3 exhibited a high photoabsorption property with band gap energy of ≈ 2.5\ua0eV. The methyl orange (MO) degradation properties were studied by measuring time-dependent UV–Visible absorption of the dye solution. The photocatalytic activity was evaluated at different times under visible light and ambient temperature conditions for La0.8Nd0.1Sr0.1MnO3 solution. A high degradation rate of 80% in 120\ua0min under UV irradiation conditions was observed. It indicated that La0.8Nd0.1Sr0.1MnO3 presents high photocatalytic efficiency and could be a good candidate for MO degradation
