Additionally, they also possess excellent photocatalytic activity and stability in the process of dechlorination of chlorophenols, which are typical persistent organic pollutants. It would be of great interest to conduct in situ (photo‐) catalysis investigations during the whole photocatalytic process by SHG when considering them as photocatalytic materials. In order to get superior photocatalytic efficiency and maximum surface information, small particles are highly desired. Here, a low‐cost and fast synthesis route that allows growing microcrystalline optically nonlinear Pb2B5O9X borate halides at large quantities is introduced. When applying the ionothermal growth process at temperatures between 130 and 170 °C, microcrystallites with an average size of about 1 µm precipitate with an orthorhombic hilgardite‐like borate halide structure. Thorough examinations using powder X‐ray diffraction and scanning electron microscopy, the Pb2B5O9X microcrystals are indicated to be chemically pure and single‐phased. Besides, the Pb2B5O9X borate halides' SHG efficiencies are confirmed using confocal SHG microscopy. The low‐temperature synthesis route thus makes these borate halides a highly desirable material for surface studies such as monitoring chemical reactions with picosecond time resolution and in situ (photo‐) catalysis investigations. article_number: '2000857' article_type: original author: - first_name: Deming full_name: Tan, Deming last_name: Tan - first_name: Benjamin full_name: Kirbus, Benjamin last_name: Kirbus - first_name: Michael full_name: Rüsing, Michael id: '22501' last_name: Rüsing orcid: 0000-0003-4682-4577 - first_name: Tobias full_name: Pietsch, Tobias last_name: Pietsch - first_name: Michael full_name: Ruck, Michael last_name: Ruck - first_name: Lukas M. full_name: Eng, Lukas M. last_name: Eng citation: ama: Tan D, Kirbus B, Rüsing M, Pietsch T, Ruck M, Eng LM.

Here, a shallow-etched ridge waveguide is fabricated in x-cut magnesium oxide doped TFLN and is poled accurately over 5 mm. The high fidelity of the poling is demonstrated over long lengths using a non-destructive technique of confocal scanning second-harmonic microscopy. We report a second-harmonic conversion efficiency of up to 939 %/W (length-normalized conversion efficiency 3757 %/Wcm²), measured at telecommunications wavelengths. The device demonstrates a narrow spectral linewidth (1 nm) and can be tuned precisely with a tuning characteristic of 0.1 nm/°C, over at least 40 °C without measurable loss of efficiency. article_number: '19669' article_type: original author: - first_name: Jie full_name: Zhao, Jie last_name: Zhao - first_name: Michael full_name: Rüsing, Michael id: '22501' last_name: Rüsing orcid: 0000-0003-4682-4577 - first_name: Usman A. full_name: Javid, Usman A. last_name: Javid - first_name: Jingwei full_name: Ling, Jingwei last_name: Ling - first_name: Mingxiao full_name: Li, Mingxiao last_name: Li - first_name: Qiang full_name: Lin, Qiang last_name: Lin - first_name: Shayan full_name: Mookherjea, Shayan last_name: Mookherjea citation: ama: Zhao J, Rüsing M, Javid UA, et al.

Shaped single-voltage poling pulses were applied to electrode structures that were fabricated by a combination of electron-beam and direct-writing laser lithography. Evidence of successful poling with good quality was obtained through second-harmonic microscopy and piezoresponse force microscopy imaging.

While supervised learning methods need an enormous amount of reliable ground truth data to find rather inflexible patterns, classical unsupervised learn- ing techniques need a lot of computational power to handle large amount of data. This makes them infeasible for real- time analysis. In this work, we demonstrate the applicability of text stream clustering for the real-time detection of coordi- nated campaigns. author: - first_name: D full_name: Assenmacher, D last_name: Assenmacher - first_name: L full_name: Adam, L last_name: Adam - first_name: Heike full_name: Trautmann, Heike id: '100740' last_name: Trautmann orcid: 0000-0002-9788-8282 - first_name: C full_name: Grimme, C last_name: Grimme citation: ama: 'Assenmacher D, Adam L, Trautmann H, Grimme C.

Jahrhunderts aus sprachwissenschaftlicher Perspektive untersucht. Es wird gezeigt, wie sich das Textsortenrepertoire der Zeitung weiterentwickelte, welche sprachlichen Wandelprozesse stattfanden und wie die Zeitung übergreifend allmählich zu einem Massenmedium avancierte. Der textlinguistische Zugang auf die Zeitungssprache wird an den relevanten Stellen ergänzt durch einschlägige Erkenntnisse aus der historischen Presseforschung und der linguistischen Kulturanalyse. So wird etwa nachgezeichnet, wie sich die Zeitungsschreiber im Laufe des Jahrhunderts immer stärker von den Einflüssen der Kanzleisprachen lösten und Formulierungsstrategien etablierten, die auf die Anforderungen des journalistischen Berichtens abgestimmt waren. Mit diesen und weiteren Ergebnissen wird der Versuch angestellt, eine Forschungslücke der Sprachgeschichtsforschung zu schließen, in der die Zeitungen des 18. Jahrhunderts bisher lediglich randständig untersucht wurden. author: - first_name: Manuel full_name: Wille, Manuel id: '9310' last_name: Wille citation: ama: Wille M. Die Tageszeitung des 18.
