The reflected Bragg signal shows a distinct peak splitting correlated to substrate anisotropies originating from the injection molding process. Especially at low H2 concentrations, both sensing peaks exhibit an outstanding response to the heat generated by the exothermic reaction between hydrogen molecules and coating. Thereby, a hydrogen volume ratio of 50 ppm leads to a Bragg wavelength shift of -37 pm, which yields an outstandingly low detection limit of only 5 ppm H2 in air. Thus, functionalized polymer planar Bragg gratings are eminently suitable for H2 leak detection applications.}, subject = {Gassensor}, language = {en} } @inproceedings{Klopp2020, author = {Klopp, Marco}, title = {Work-in-Progress: Learning Culture of Generation Z in Informatics}, publisher = {IEEE}, pages = {1589 -- 1593}, year = {2020}, abstract = {A new generation of students is entering the university - Generation Z. This generation is characterized mainly by the existing digitization, since they grew up entirely in it. With regard to different generations, the relationship of the different ages and the associated large cohort difference in the interaction between lecturers and learners should be taken into account and analysed. It's important because, according to the Hattie study, the most important influencing factor for the learning success of learners are the teachers. This means that excellence in teaching (according to the characteristics of the learners) is the most important single factor for the learning outcome. In order to draw the link to Informatics, the consideration of the subject-related culture and the connected learning culture is of central importance. It is obvious to recognize learning cultures in their cultural context, in their reasons and with their consequences for lecturers and students. Frames are therefore not static, but socially constructed and therefore changeable. Learning cultures are created in a communicative negotiation process by all actors in a learning situation. Subject-related culture research also deals with the question of whether and to what extent university teaching differs and which different behaviors can be found among its members. The aim is to classify the Informatics subject-related culture and to describe the ideas and expectations of lecturers and students in the learning environment and in the various social contexts of Informatics, and to reconstruct implicit, practical knowledge for the improvement of learning in Informatics.}, subject = {Generation Geschichte 1995-2010}, language = {en} } @inproceedings{SchwarzRungEsenetal.2020, author = {Schwarz, Simon and Rung, Stefan and Esen, Cemal and Hellmann, Ralf}, title = {All laser-based fabrication of optical elements}, series = {Proceedings of SPIE 11270, Frontiers in Ultrafast Optics: Biomedical, Scientific, and Industrial Applications XX}, booktitle = {Proceedings of SPIE 11270, Frontiers in Ultrafast Optics: Biomedical, Scientific, and Industrial Applications XX}, year = {2020}, subject = {Ultrakurzzeitlaser}, language = {de} } @article{DudutisPipirasSchwarzetal.2020, author = {Dudutis, Juozas and Pipiras, Jokūbas and Schwarz, Simon and Rung, Stefan and Hellmann, Ralf and Račiukaitis, Gediminas and Gečys, Paulius}, title = {Laser-fabricated axicons challenging the conventional optics in glass processing applications}, series = {Optics Express}, volume = {28}, journal = {Optics Express}, number = {4}, pages = {5715 -- 5730}, year = {2020}, subject = {Laserbearbeitung}, language = {en} }
