Commissioning an Inexpensive Off‐The‐Shelf Spectrograph for Radial‐Velocity Studies

Astronomische Nachrichten, EarlyView.
ABSTRACT We present a way to set up an inexpensive out of the shelf spectrograph at a local observatory. Stability and resolution of the spectrograph are high enough for radial velocity determination of binary stars or determination of stellar characteristics. Even some exoplanets might be detectable via the radial velocity method.

Discovery and Initial Investigation of a New Low Surface Brightness Planetary Nebula Candidate at High Galactic Latitude

Astronomische Nachrichten, EarlyView.
ABSTRACT Planetary nebulae represent a late evolutionary phase of low‐ to intermediate‐mass stars. In this article, we present the serendipitous discovery of a previously unknown, faint potential Galactic planetary nebula (PN) in the constellation Camelopardalis, identified during a survey‐inspection, aiming at the detection of dwarf companions of the ...

Understanding Degradation Mechanisms in Water‐In‐Salt Electrolyte. Part 2: Impact of the Electrochemical Parameters on the Cycling Behavior of LiFePO4 versus TiS2

Batteries &Supercaps, EarlyView.
Cycling water‐in‐salt batteries involves complex degradation processes that require multiprobe analysis. Using online electrochemical mass spectrometry (OEMS), postmortem X‐ray photoemission spectroscopy (XPS) (including hard‐XPS), and scanning electron microscopy (SEM), the degradation mechanisms are examined in composite electrodes (TiS2 and LiFePO4)

Reduction and Solid Electrolyte Interphase Formation Mechanism of Prop‐1‐ene‐1,3‐Sultone

Batteries &Supercaps, EarlyView.
Layer‐forming additives stabilize Li‐ion cells, yet their mechanisms remain unclear. Using operando attenuated total reflection fourier‐transform infrared spectroscopy, online electrochemical mass spectrometry, electrochemical quartz crystal microbalance with dissipation monitoring, electrochemical impedance spectroscopy, and ex situ X‐ray ...
