Membran‐Bioreaktor‐Technik kombiniert mit nachgeschalteter Ozonung – Vergleich mit konventionellen Ozonanwendungen Combination of Membrane Bioreactor and Downstream Ozonation – A Comparison to Conventional Ozone Applications

Chemie Ingenieur Technik, EarlyView.
Kommunale Kläranlagen gelten als Haupteintragspfad organischer Mikroschadstoffe in die aquatische Umwelt. Ein Großteil der Arzneimittelrückstände und Industriechemikalien wird in Kläranlagen nicht oder nur teilweise entfernt. Um einen qualitativ höheren Kläranlagen‐Ablauf zu erzeugen, wird eine Kombination aus hybridem Teilstrom‐Membran‐Bioreaktor mit ...

Linear and Two‐Dimensional Infrared Spectroscopy of the Multifunctional Vibrational Probe, 3‐(4‐Azidophenyl) Propiolonitrile. Deperturbing a Fermi Triad by Isotopic Substitution

ChemPhysChem, Volume 26, Issue 6, March 15, 2025.
Linear infrared spectroscopy combined with isotope labeling and density functional theory unravels the origin of a Fermi triad in a multifunctional vibrational chromophore. Ultrafast 2DIR‐spectroscopy reports directly on the dynamics and the intramolecular vibrational energy flow pathways in the isotopically deperturbed system. Abstract Infrared probes

Molecular Fragmentation as a Strategy to Access Hyperpolarized Compounds from Para‐Hydrogen

ChemPhysChem, EarlyView.
Hyperpolarization using para‐hydrogen is a simple and cost‐effective method to dramatically increase sensitivity in magnetic resonance. When combined with chemical reactions that generate smaller fragments, a much wider array of different hyperpolarized molecules can be accessed.

Field Test of a Bioelectrochemical Membrane‐Less Reactor for Chlorinated Aliphatic Hydrocarbon and Nitrate Removal From a Contaminated Groundwater

ChemPlusChem, Accepted Article.
This study uses a membrane‐less reactor to explore the bioelectrochemical remediation of real contaminated groundwater from chlorinated aliphatic hydrocarbons (CAHs) and nitrates. The research focuses on testing a column‐type bioelectrochemical reactor to stimulate in‐situ degradation of contaminants through the supply of electrons by a graphite ...

Combining photocatalytic oxidation of β‐chlorohydrins with carbonyl bioreduction in a deracemization approach

ChemSusChem, Accepted Article.
Enantiopure β‐chlorohydrins are valuable intermediates in organic synthesis, acting as chiral building blocks for obtaining biologically active compounds. This work presents a one‐pot two‐step linear sequence for the efficient deracemization of β‐chlorohydrins by combining a photocatalytic alcohol oxidation with a stereoselective carbonyl bioreduction ...

Fate of wastewater nitrogen upon injection into a coastal saline groundwater system, Florida Keys, USA

The Depositional Record, EarlyView.
Despite advanced wastewater treatment, dilution by rainwater and mixing, and microbial modification, nitrogen nutrients derived from shallowly injected wastewater are detected in nearshore waters in the Florida Keys. Abstract Injection of treated wastewater into the shallow subsurface on islands and along coastlines is a common practice in areas like ...
