WATER EDUCATION: AN E-LEARNING PLATFORM FOR WATER- RELATED COMPETENCE DEVELOPMENT

ABSTRACT The Danish water sector needs competence development as a response to changing water management structures and implementation of European legislation, and the number of international students enrolled in at DTU Environment is increasing. Based on their different backgrounds there is a clear need for adaptation and development of the existing courses. To accommodate this, DTU Environment has created an e-learning platform called Water Education, based on the software platform Moodle. It is scheduled to be operational in 2011. Based on the experiences so far, it can be concluded that in some areas major time savings can be obtained during the course execution and increased learning has been documented compared to a traditional classroom teaching on the same topic, but the students' backgrounds affect their attitude towards e-learning. More recorded lectures are sought and presents a potentially positive way forward

Comment on "bi-functional Li2 B12 H12 for energy storage and conversion applications: Solid-state electrolyte and luminescent down-conversion dye" by J. A. Teprovich Jr, H. Colón-Mercado, A. L. Washington II, P. A. Ward, S. Greenway, D. M. Missimer, H. Hartman, J. Velten, J. H. Christian and R. Zidan,: J. Mater. Chem. A, 2015, 3, 22853

The photoluminescent properties of selected metal closo-boranes have been assessed. Group 3 elements Sc, Y, and La as well as Li, Na, and Eu-based B 10 H 102- and B 12 H 122- compounds displayed photoluminescence in the ultraviolet (emission λ max ≈ 350 nm) that was not visible to the human eye, in contrast to previous reports. We attribute these earlier results to arachno-borane impurities, which are more readily observed due to their longer wavelength emission spectra

Synergistic effect of carotenoid and silicone-based additives for photooxidatively stable organic solar cells with enhanced elasticity

Photochemical and mechanical stability are critical in the production and application of organic solar cells. While these factors can individually be improved using different additives, there is no example of studies on the combined effects of such additive-assisted stabilization. In this study, the properties of PTB7:[70]PCBM organic solar cells are studied upon implementation of two additives: the carotenoid astaxanthin (AX) for photochemical stability and the silicone polydimethylsiloxane (PDMS) for improved mechanical properties. A newly designed additive, AXcPDMS, based on astaxanthin covalently bonded to PDMS was also examined. Lifetime tests, produced in ISOS-L-2 conditions, reveal an improvement in the accumulated power generation (APG) of 10% with pure AX, of 90% when AX is paired with PDMS, and of 140% when AXcPDMS is added in the active layer blend, as compared to the control devices. Singlet oxygen phosphorescence measurements are utilized to study the ability of AX and AXcPDMS to quench singlet oxygen and its precursors in the films. The data are consistent with the strong stabilization effect of the carotenoids. While AX and AXcPDMS are both efficient photochemical stabilizers, the improvement in device stability observed in the presence of AXcPDMS is likely due to a more favorable localization of the stabilizer within the blend. The mechanical properties of the active layers were investigated by tensile testing and cohesive fracture measurements, showing a joint improvement of the photooxidative stability and the mechanical properties, thus yielding organic solar cell devices that are promising for flexible photovoltaic applications. © The Royal Society of Chemistry 2021.12 month embargo; first published: 07 July 2021This item from the UA Faculty Publications collection is made available by the University of Arizona with support from the University of Arizona Libraries.
