Physik in unserer Zeit, Volume 54, Issue 6, Page 302-304, November 2023., 2023 Die Harfe ist ein uraltes Instrument, das in vielen Kulturen und Varianten gespielt wird – überwiegend von Frauen. Anders als traditionelle Instrumente ist die moderne Konzertharfe ohne mühsames Umstimmen der Saiten in allen Tonarten spielbar, erfordert aber engagierte Fußarbeit.

3D‐Printed Anisotropic Nanofiber Composites with Gradual Mechanical Properties
Advanced Materials Technologies, Volume 8, Issue 10, May 25, 2023., 2023 The development of 3D‐printed nanofiber biocomposites with mechanical, structural, and swelling anisotropy is demonstrated. The hydrophilic and ionically crosslinked nanocellulose‐based composites exhibit outstanding properties such as high shape fidelity, wet strength, stability, and resistance to pressure, temperature, and biological fluids.

Physik in unserer Zeit, Volume 54, Issue 3, Page 132-133, May 2023., 2023 Beim Alphorn werden die verschiedenen Klänge durch Überblasen eines Grundtons in die Naturtonreihe erzeugt. Im Didgeridoo wird meist nur der Grundton angeregt, aber mit einer Klangvielfalt, die überrascht. Zusammenfassung Obwohl das Didgeridoo eines der konstruktiv einfachsten Instrumente ist, zeigt es dennoch eine sehr variable Klangvielfalt.

High‐Order Fiber Bragg Grating Corrosion Sensor Based on the Detection of a Local Surface Expansion
Structural Control and Health Monitoring, Volume 2023, Issue 1, 2023., 2023 This paper presents a fiber optic sensor for the detection of corrosion processes that occur on metal surfaces. In the proposed sensor design, a sensing fiber with an inscribed high‐order Bragg grating is attached to the observed metal surface. A broadening of high‐order Bragg grating spectral characteristics is observed and used to detect small and ...

Physik in unserer Zeit, Volume 53, Issue 3, Page 140-141, May 2022., 2022 Bei Musik und Sprache denkt man automatisch an harmonische Klänge. Rauschen ist jedoch ebenfalls ein essentieller Bestandteil, insbesondere beim Sprechen. Es wird sogar medizinisch genutzt. Zusammenfassung Bei Musik und Sprache denkt man automatisch an harmonische Klänge. Rauschen ist jedoch ebenfalls ein essentieller Bestandteil.

Photonic Bandgap in Achiral Liquid Crystals—A Twist on a Twist
Advanced Materials, Volume 33, Issue 39, October 1, 2021., 2021 The photonic bandgap phenomenon is observed in a liquid crystalline phase built of achiral molecules, in which a tendency to twist is caused by steric interactions between strongly bent molecules. A selective reflection of visible light appears due to unwinding of the helical structure at the transition between two smectic phases having a single‐ and ...

Physik in unserer Zeit, Volume 52, Issue 3, Page 138-139, May 2021., 2021 Ein Spielzeug‐Xylophon ist meist das erste Instrument unserer Kindheit. Xylophone und Marimbas gab es bereits in der Antike. Ihre Klangeigenschaften basieren auf einem interessanten Schwingungsverhalten. Zusammenfassung Ein Spielzeug‐Xylophon ist meist das erste Instrument unserer Kindheit – wenn auch mit Metallplättchen als Klangerzeuger.

Phylogenetic relationships and sectional delineation within Gentiana (Gentianaceae)
TAXON, Volume 69, Issue 6, Page 1221-1238, December 2020., 2020 Abstract Gentiana is a sub‐cosmopolitan temperate genus among the most species‐rich in Gentianaceae. Although molecular data (produced via Sanger sequencing) allowed the resolution of phylogenetic relationships between Gentiana and other genera in subtribe Gentianinae, the validity of sections within the genus remains largely untested.
