Cooperative Redox Catalysis of N2O Decomposition by Short‐Range RhOx and CeOx Anchored to Co3O4

Angewandte Chemie International Edition, EarlyView.
A short‐range Rh–O–Co–O–Ce interfacial moiety drives low‐temperature N2O decomposition via a cooperative redox cycle. Operando modulated‐excitation XAS with phase‐sensitive detection (ME‐XAS + PSD) tracks rapid, reversible Rh oxidation coupled to Co reduction.

Photochemistry of Aromatic N‐Oxides in Water Probed by Time‐Resolved X‐ray Absorption Spectroscopy

Chemistry – A European Journal, EarlyView.
Time‐resolved XAS at the nitrogen and oxygen K‐edges is applied to the photorearrangement of two N‐oxides in water. Pyridine N‐oxide rapidly forms the oxaziridine isomer. Pyridazine N‐oxide undergoes ring opening to the diazo compound, without any evidence of intermediates.

Energy Balancing of Electrochemical Alternatives to the Solvay Process

Chemie Ingenieur Technik, EarlyView.
To overcome the CaCl2 and CO2 emissions custom to the conventional Solvay process in soda ash production, electrochemically based alternatives were investigated. In particular, the mass‐ and energy balances for chlor‐alkali electrolysis and bipolar electrodialysis‐based processes are discussed comprehensively in the presented work.

A Short‐Cut Design Approach to Evaluate Reboiler Designs in Vapor Recompression Scenarios

Chemie Ingenieur Technik, EarlyView.
A short‐cut model framework that incorporates mechanical vapor recompression (MVR) requirements into reboiler design is presented, which is particularly beneficial during early process development with limited data or initial feasibility assessments.

Nichtlineare Staubungsneigung binärer Schüttgutmischungen: Herausforderungen bei der Prognose Non‐linear dusting tendency of binary bulk material mixtures: Challenges in prognosis

Chemie Ingenieur Technik, EarlyView.
Aufgrund überlagerter oder konkurrierender Mechanismen sind relevante Wechselwirkungen bei der Staubung von Schüttgutmischungen komplex und nur unzureichend verstanden. Selbst für Mischungen aus umfassend charakterisierten Einzelkomponenten existieren keine belastbaren Modelle. In dieser Arbeit werden die Hürden bei der Prognose thematisiert.

MIDDLE-LATE MIOCENE TIDAL-RELATED DEPOSITS OF THE BINIO FORMATION: THE SEDIMENTARY AND STRATIGRAPHIC RECORDS DURING INVERSION OF THE CENTRAL SUMATRA BASIN, INDONESIA

Rudarsko-geološko-naftni Zbornik
The distribution of tidal-related deposits can be controlled by structural growth. This structural growth can be reflected, for example, by inversion structures in a back-arc basin.
