Retracted: Can the chemical industry solve the climate change?On the role of human energy production, renewable energies, and the potential of chemistry as a solution provider

open access: yesChemie Ingenieur Technik, EarlyView., 2023
Let us consider an alternative perspective on climate change: The sum of solar radiation and heat generated by human activity result in a net energy input of 1.96 times that of the Sun on the Earth's surface. The expanding global population is expected to exacerbate this issue. Potential solutions are proposed, including replacement and heat recycling.

New Light on Dark Extended Lenses with the Roman Space Telescope

open access: yesThe Astrophysical Journal Letters
The Roman Space Telescope’s Galactic Bulge Time Domain Survey will constitute the most sensitive microlensing survey of the Galactic bulge to date, opening up new opportunities to search for dark matter (DM). Many extensions of the Standard Model predict

A Bias‐Tunable Multispectral Photodetector Based on a GaN/TexSe1‐x Homo‐Type Heterojunction with a Unidirectional Barrier

open access: yesAdvanced Science, EarlyView.
A bias‐tunable multispectral photodetector based on a TexSe1‐x/GaN homo‐type heterojunction with a unidirectional barrier is proposed. By modulating the bias polarity and magnitude, the device's spectral response range can be extended from UV to the SWIR region.

A Web Tool for Calculating Substituent Descriptors Compatible with Hammett Sigma Constants**

open access: yesChemistry–Methods, Volume 2, Issue 12, December 2022., 2022
A method to calculate substituent descriptors compatible with the Hammett σ constants using quantum chemical parameters is described, and a free web tool allowing to calculate electronic and hydrophobic substituent descriptors is made available at https://bitly.com/getsigmas.

Correlations in Magnetic Sub‐Domains as an Unconventional Phase Diagram for van der Waals Ferromagnets

open access: yesAdvanced Science, EarlyView.
An unconventional magnetic order is observed in exfoliated CrBr3 layers, characterized by vertically correlated planar magnetic sub‐domains. Magnetic force microscopy, ab initio calculations, and micromagnetic simulations indicate that these sub‐domains arise from stacking faults modifying interlayer exchange coupling.

Maser Investigation toward Off-Plane Stars (MIOPS): Detection of SiO Masers in the Galactic Thick Disk and Halo

open access: yesThe Astrophysical Journal
Studying stars that are located off the Galactic plane is important for understanding the formation history of the Milky Way. We searched for SiO masers toward off-plane O-rich asymptotic giant branch (AGB) stars from the catalog presented by Mauron et ...
