The Preparatory (Anti)Bonding Character of Molecular Orbitals
Advanced Science, EarlyView.Herein, a concept to qualitatively predict changes in bond dissociation energies upon reduction or oxidation of molecular compounds is introduced. Changing the population of so‐called preparatory molecular orbitals influences how molecular fragments are relaxing after bond cleavage, which is shown for isolated organometallic aluminum compounds as well ...

Thermal Activation and Deactivation of Ni‐Doped Ceria Catalysts in CO2 Methanation
Small ScienceDiscovered almost 130 years ago by P. Sabatier, CO2 hydrogenation to methane (CO2 methanation) is presently attracting attention as one of the most promising methods for storing intermittent renewable energy in the form of chemical fuels.

Journal of CO2 UtilizationThe use of synthetic natural gas (SNG) as a plug-and-play fuel coming from renewables can help to overcome the limitations given by the intermittency of renewable energy. A way to implement the production of SNG pass through the co-electrolysis of CO2 to

Chemoselective Metabolomics via a Modular Reactivity‐Encoding Platform
Advanced Science, EarlyView.Conventional LC–MS underrepresents numerous metabolites due to heterogeneous ionization efficiencies and matrix interference. Here, we introduce a modular reactivity‐encoding platform (MREP) comprising four alkyne‐tagged probes that selectively derivatize key functional groups, followed by unified click‐chemistry capture to eliminate matrix components ...

Advanced Science, EarlyView.Conceptual illustration of a Global Ecosystem Methane Observing System (GEM‐OS) integrating satellites, aircraft, atmospheric networks, and ecosystem measurements to quantify methane emissions from anthropogenic and natural sources. The multi‐scale observing framework improves source attribution, reduces uncertainty in regional methane budgets, and ...

Advanced Science, EarlyView.Our findings establish SUMOylation as a key post‐translational control layer in auxin signaling. We show that SIZ1‐mediated SUMOylation of LBD29 promotes its association with ARF7, stabilizing a transcriptional hub that governs lateral root development.
