@article{2091, abstract = { In times of climate change and increasing resource scarcity, the importance of sustainable renewable energy technologies is increasing. However, the photovoltaic (PV) industry is characterised by linear economy structures, energy-intensive production, downcycling and little sustainability. One starting point for sustainable technologies is offered by the circular economy with its circular design principles. One problematic aspect of the design of crystalline PV modules is the encapsulation. In particular, the encapsulation avoids high-value recycling or the remanufacturing of modules, which could close loops and extend the lifetime of the products. For this reason, this paper provides an overview of the current state of encapsulation methods regarding production, materials and recycling. In addition, the current state of sustainability research in the photovoltaic sector is presented using the VOSviewer tool. Furthermore, alternative encapsulation technologies are discussed and compared in terms of performance and sustainability. The current encapsulation method using ethylene vinyl acetate as the encapsulation material offers major disadvantages in terms of performance and recyclability. Alternatives are the thermoplastic material polyolefin and the alternative structure of the NICE technology. Overall, however, research should focus more on sustainability and recyclability. Alternative module structures will be a decisive factor in this context. }, author = {Schnatmann, Anna Katharina and Schoden, Fabian and Schwenzfeier-Hellkamp, Eva}, issn = {2071-1050}, journal = {Sustainability}, keywords = {circular economy, encapsulation, crystalline photovoltaic, sustainability}, number = {16}, publisher = {MDPI AG}, title = {{Sustainable PV Module Design—Review of State-of-the-Art Encapsulation Methods}}, doi = {10.3390/su14169971}, volume = {14}, year = {2022}, } @article{678, abstract = {Asymmetric magnetic hysteresis loops are usually found in exchange bias (EB) systems, typically after field cooling a system below the Néel temperature of an antiferromagnet exchange coupled to a ferromagnet. Alternatively, asymmetric hysteresis loops may occur due to undetected minor loops or in systems with a rotational anisotropy. Here, we report on an exchange bias thin film system MgO(100)/Co/CoO, examined at room temperature, which is far above the blocking temperature, by the magneto-optical Kerr effect (MOKE). While the longitudinal hysteresis loops partly show steps which are well-known from diverse purely ferromagnetic systems, the transverse hysteresis loops exhibit clear asymmetries, similar to exchange biased systems at low temperatures, and unusual transverse magnetization values at saturation. Since minor loops and a rotational anisotropy can be excluded in this case, this asymmetry can possibly be a residue of the exchange bias coupling at lower temperatures.}, author = {Ehrmann, Andrea and Blachowicz, Tomasz}, issn = {2410-3896}, journal = {Condensed Matter}, keywords = {exchange bias, rotatable anisotropy, blocking temperature, minor loops, Co/CoO}, number = {4}, title = {{Asymmetric Hysteresis Loops in Co Thin Films}}, doi = {10.3390/condmat5040071}, volume = {5}, year = {2020}, } @article{199, abstract = {BACKGROUNDWireworms (Coleoptera: Elateridae) are major insect pests of worldwide relevance. Owing to the progressive phasing-out of chemical insecticides, there is great demand for innovative control options. This study reports on the development of an attract-and-kill co-formulation based on Ca-alginate beads, which release CO2 and contain neem extract as a bioinsecticidal compound. The objectives of this study were to discover: (1) whether neem extract can be immobilized efficiently, (2) whether CO2-releasing Saccharomyces cerevisiae and neem extract are suitable for co-encapsulation, and (3) whether co-encapsulated neem extract affects the attractiveness of CO2-releasing beads towards wireworms. RESULTSNeem extract was co-encapsulated together with S. cerevisiae, starch and amyloglucosidase with a high encapsulation efficiency of 98.6\% (based on measurement of azadirachtin A as the main active ingredient). Even at enhanced concentrations, neem extract allowed growth of S. cerevisiae, and beads containing neem extract exhibited CO2-emission comparable with beads without neem extract. When applied to the soil, the beads established a CO2 gradient of >15 cm. The co-formulation containing neem extract showed no repellent effects and was attractive for wireworms within the first 24 h after exposure. CONCLUSIONCo-encapsulation of S. cerevisiae and neem extract is a promising approach for the development of attract-and- kill formulations for the control of wireworms. This study offers new options for the application of neem extracts in soil.

The authors explore this influence with the support of social exchange theory and resource-based view. Design/methodology/approach – The methodology applied was qualitative research, based on 29 semi-structured in-depth interviews with owners, managing directors and technical managers with previous experience in co-creation processes. The research was performed in four different European countries and is focused on the mobile crane industry. Findings – The findings suggest that co-creation processes promote the generation of dynamic capabilities linked to adaptation, knowledge, innovation and relationship management. In addition, the closer contact with customers and the availability of their expertise favour the development of solutions that better meet their needs, bridging the cognitive gap which often exists between partners. Regarding customer retention, the results show that co-creation processes foster customer predisposition to buy and cross-sell. Originality/value – Although value co-creation is a topical subject, research in industrial marketing literature analysing the effects of co-creation processes has been scarce up to now. This paper aims to contribute to the debate by analysing how the co-creation of value can influence the generation of dynamic capabilities in companies and how it affects the retention of industrial customers. Based on social exchange theory and dynamic capabilities, the researchers have been able to address how value is developed and its influence in customer retention proxies}, author = {Preikschas, Michael W. and Cabanelas, Pablo and Rüdiger, Klaus and Lampón, Jesús}, issn = {0885-8624}, journal = {Journal of Business & Industrial Marketing}, keywords = {Value co-creation, Qualitative research, Business strategy, Customer retention, Dynamic capabilities, Industrial marketing}, number = {3}, pages = {409--420}, publisher = {Emerald Publishing Limited}, title = {{Value co-creation, dynamic capabilities and customer retention in industrial markets}}, doi = {10.1108/JBIM-10-2014-0215}, volume = {33}, year = {2017}, }
