On the lithium abundance of the visual binary components ξ Boo A (G8V) and ξ Boo B (K5V)
Astronomische Nachrichten, Volume 343, Issue 9-10, November-December 2022., 2022 Abstract A spectroscopic investigation of the lithium resonance doublet in ξ Boo A and ξ Boo B in terms of both abundance and isotopic ratio is presented. We obtained new R = 130,000 spectra with a signal‐to‐noise ratio (S/N) per pixel of up to 3200 using the 11.8 m LBT and PEPSI.

Advanced Science, EarlyView.The origin and nature of metal‐substrate interface layer in Ta/sapphire‐based superconducting films is investigated using synchrotron X‐ray reflectivity and scanning transmission electron microscopy. An intermixing layer, ≈0.65 nm thick containing Al, O, and Ta atoms, is identified at the interface.

Astronomische Nachrichten, Volume 343, Issue 9-10, November-December 2022., 2022 Abstract The advent of ultra‐precise photometry space missions enables the possibility of investigating stellar interiors with mixed modes. The structural variations induced by the discontinuity of the chemical composition left behind during the first dredge–up is an important feature in the stellar mid‐layers located between the hydrogen‐burning shell

Advanced Science, EarlyView.How does flexible and achiral glycine affect suprastructural handedness in peptide self‐assembly? A series of short peptides containing glycine is designed, and different molecular conformations caused by varying the position of glycine can lead to different hydrogen bonding patterns upon forming β‐sheets, eventually resulting in variations in their ...
