The Schumann-Runge absorption bands of 16O 18O in the wavelength region 175-205 nm and spectroscopic constants of isotopic oxygen molecules

, 1989
High-resolution absorption spectra of 16O 18O have been photographed, at 300 and 78 K, throughout the region 175-205 nm, in the first order of a 2400 lines/mm grating in a 6.65-m vacuum spectrograph at a dispersion of 0.06 nm/mm.

Cryogenic Deformation Behavior of TiAl and Insights Into Embrittlement After High‐Temperature Exposure Combined With Secondary Ion Mass Spectroscopy of Near Surface Chemistry

Advanced Engineering Materials, EarlyView.
Near‐surface deuterium enrichment profiles for different microstructural types of TiAl after exposure at 700 °C in a heavy water‐containing environment. The deuterium levels are significantly higher than expected from natural occurrence, indicating that the heavy water dissociated during the exposure treatment and entered the specimens.

Formation pathways and detectability of interstellar C2HNO-bearing molecules

Astronomy & Astrophysics
Aims. We explored N-bearing molecules of the general formula C2HNO. We provide their spectroscopic constants, structural properties relevant for detection, and reaction pathways to constrain their formation in the interstellar medium. Methods.

Spectroscopic constants from atomic properties: a machine learning approach [PDF]

We present a machine-learning approach toward predicting spectroscopic constants based on atomic properties. After collecting spectroscopic information on diatomics and generating an extensive database, we employ Gaussian process regression to identify ...

The Role of Ultra‐Thin Passive Films and Organic Adsorbates on Aluminum Chips for a Friction‐Induced Solid‐State Recycling Process

Advanced Engineering Materials, EarlyView.
Despite benefits to storage stability and handleability of aluminum scrap, octadecyl phosphonic acid (ODPA) SAMs reduce the tensile strength of wires produced using friction‐induced recycling. Etching and methyl diphosphonic acid (MDPA) coatings, however, have little effect.

Enhancing Low‐Temperature Performance of Sodium‐Ion Batteries via Anion‐Solvent Interactions

Advanced Functional Materials, EarlyView.
DOL is introduced into electrolytes as a co‐solvent, increasing slat solubility, ion conductivity, and the de‐solvent process, and forming an anion‐rich solvent shell due to its high interaction with anion. With the above virtues, the batteries using this electrolyte exhibit excellent cycling stability at low temperatures. Abstract Sodium‐ion batteries
