Heterovalent, Homometallic Rings: Synthesis, Optical, and EPR Studies of {TiIV7TiIII} Complexes

Chemistry – A European Journal, EarlyView.
A new class of heterovalent, homometallic complexes is reported, based on cyclic {TiIV7TiIII} cores with oxide and carboxylate bridges between nearest neighbors. The clusters show Class II mixed‐valent behavior at room temperature, but are valence localized at low temperature.

Exploring the Boundaries of Aromaticity in Complex Structures and Excited States Through Computational Analysis

Chemistry – A European Journal, EarlyView.
Understanding aromaticity has evolved from benzene‐centric concepts to a broad multidimensional framework spanning organic, inorganic, and excited‐state systems. This review highlights ambiguities between magnetic, electronic, geometric, and energetic descriptors, emphasizing the need for unified, multi‐criteria approaches.

Using Displacement‐Assisted Desorption to Identify Reactive Intermediates: Ring‐Fused Porphyrins on Cu(111)

Chemistry – A European Journal, EarlyView.
We propose a novel displacement‐assisted approach for temperature‐programmed desorption (TPD), allowing for the detection of reactive intermediates of on‐surface reactions. We demonstrate the approach by investigating the temperature‐dependent ring fusion reactions (cyclodehydrogenations) of tetraphenylporphyrin on Cu(111), revealing the quantitative ...

Direct Observation of a Hydrogen‐Bonding Assisted Quasi‐Reversible Superoxo/Peroxo Interconversion in a Heme Model

Chemistry – A European Journal, EarlyView.
First direct observation of a quasi‐reversible superoxo (FeIII─O2˙ˉ)/peroxo (FeIII─O22ˉ) redox couple in a heme model complex, featuring a biologically relevant low‐spin ferric end‐on peroxo species stabilized by second‐sphere hydrogen bonding. These findings highlight the key role of second‐sphere interactions in modulating O2 activation pathways ...

Transcriptomic Profiling of SLC and ABC Transporters in the Human Term Placenta

Clinical Pharmacology &Therapeutics, EarlyView.
Solute carriers (SLC) and ATP‐binding cassette (ABC) transporters are essential for placental solute exchange and fetal protection, yet their transcriptomic profiles in the human placenta remain poorly characterized. Although fetal sex influences placental development and function, its impact on transporter expression is unclear.
