Confirmation of a Non‐Transiting Planet in the Habitable Zone of the Nearby M Dwarf L 98‐59

Astronomische Nachrichten, EarlyView.
ABSTRACT Only 40 exoplanetary systems with five or more planets are currently known. These systems are crucial for our understanding of planet formation and planet‐planet interaction. The M dwarf L 98‐59 has previously been found to show evidence of five planets, three of which are transiting.

The Characterization of the Mechanical Harmonic Oscillator Extremum Envelope Shape According to Different Friction Types

Axioms
To characterize a phenomenological model of a mechanical oscillator, it is important to know the properties of the envelope of the three main physical motion variables: deviation from equilibrium, velocity, and acceleration.

Correcting Errors in the Adsorbed Intermediates of CO2 Electroreduction

Carbon Energy, EarlyView.
Flying over Jacob's ladder of density functional approximations: chemical accuracy in the DFT‐based modeling of CO2 reduction electrocatalysis can be approached with our simple semiempirical method to deconvolute and correct gas‐phase errors and adsorbed‐phase errors.

Supramolecular Host‐Guest Complexation Dynamics by Cost‐Efficient Electronic Structure Methods

Chemistry – A European Journal, EarlyView.
We present a cost‐effective multilevel workflow for the kinetic profiling of host–guest systems, illustrated with cucurbit[6]uril and alkylammonium cations. The method combines rapid docking and reaction path searches at the semi‐empirical level, with refinement of the results using modern density functional theory, accurately reproducing experiment ...

Twisted 1‐ and 2‐Azaperopyrenes: Synthesis, Structure, and Properties

Chemistry – A European Journal, EarlyView.
ABSTRACT A synthesis of hitherto unknown 1‐ and 2‐azaperopyrenes, twisted nitrogen‐doped peropyrenes, is reported. The synthesis is based on a Brønsted acid‐mediated benzannulation of alkynes. Key alkyne intermediates are synthesized via two complementary routes, including a Pd/C‐catalyzed, copper‐ and amine‐free Sonogashira‐type coupling of (hetero ...
