First Operation Results of a Methanol Demonstration Plant With Real Steel Mill Gases

open access: yesChemie Ingenieur Technik, EarlyView.
A demonstration plant with industrial setup regarding length, diameter, boiling water cooling system and gas recycle was initially operated with cleaned blast furnace gas and compared with earlier experiments with bottle gases. Dynamic disturbances from the steel mill and gas cleaning unit were noticed and could be compensated by the control system ...

Geological carbon dioxide storage in the German North Sea: Static‐to‐dynamic capacity refinement for a 10 Mt/y injection scenario

open access: yesDeep Underground Science and Engineering, EarlyView.
This study assesses whether a saline aquifer in the German North Sea can sustain industrial‐scale CO2 injection at 10 Mt/year over 30 years. A 3D reservoir model is used to compare static capacity with dynamically achievable storage. The work links site‐scale injection strategy design with basin‐scale pressure response, providing a framework for ...

Stabilization Strategies for Carbon Based Perovskite Solar Cells Under Light, Heat, and Humidity

open access: yesEcoEnergy, EarlyView.
Carbon‐based MA1−x(AVA)xPbI3/CsPbBr3 QD heterostructures fabricated under ambient conditions exhibit < 5% loss under ISOS‐D‐3 and reversible photo‐induced degradation, revealing the dual role of QDs in defect passivation and dynamic interfacial stabilization.

Synthetic Strategies for the Construction of Cyclobutane‐Fused Heterocycles

open access: yesEuropean Journal of Organic Chemistry, EarlyView.
Cyclobutane‐fused heterocycles are important motifs commonly present in bioactive compounds, recognized for their rigid 3D structures that confer unique properties. However, synthesizing these compounds remains challenging. This review discusses current methods for their synthesis, such as photochemical, metal‐catalyzed, and Lewis acid‐mediated [2 + 2]

A General Stereochemical Model for Grignard Additions to α‐Alkoxy Nitrones: Density Functional Theory Evidence for an Intrinsic α‐Chelation‐Controlled Pathway

open access: yesEuropean Journal of Organic Chemistry, EarlyView.
A comprehensive DFT conformational study of Grignard additions to α‐alkoxy nitrones reveals that the reaction proceeds through a dinuclear α‐chelated transition structure in which the nitrone oxygen coordinates two magnesium centers. Other common additives, such as zinc dichloride, boron trifluoride, and dimethylaluminum chloride, were also studied ...

β‐Hydroxybutyrate reduces neuronal excitability via GIRK channels

open access: yesEpilepsia, EarlyView.
β‐Hydroxybutyrate decreases neuronal excitability by activating GIRK channels through HCAR2 signaling, providing a cellular mechanism that may contribute to the antiseizure effects of the ketogenic diet. Abstract Objective The ketogenic diet is used to treat drug‐resistant epilepsy, yet the molecular mechanisms coupling metabolic state to seizure ...
