Atmospheric Science Letters, Volume 24, Issue 1, January 2023., 2023 We report on a meeting on progress and challenges in convection‐permitting data assimilation. Novel developments include the assimilation of novel observations such as cloud‐affected satellite radiances, ground‐based profiling networks and aircraft data, as well as methodological advancements in error covariance modelling, and progress in operational ...

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 ...

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.

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

Deep‐UV Light‐Emitting Based on the hBN:S/hBN: Mg Homojunction
Advanced Science, EarlyView.S‐atoms are selected as donor dopants to achieve the n‐type conductivity of the hBN film. A theoretical model of S‐doping hBN using DFT calculation and experimentally prepared S‐doped hBN multilayers with a recorded doping concentration of 1.21% is established.

Advanced Science, EarlyView.This study is the first to report the solid lubrication performance of the newly discovered Ti‐based MOF (COK‐47) powder. COK‐47 exhibits a remarkably lowest and most stable coefficient of friction compared to typical solid lubricants. The lubrication mechanism involves water molecules from the air participating in tribochemical reactions, forming an ...
