Herein, we report the stabilization of nitrene reagents as the source of a nitrogen atom to synthesize nitrogen-incorporated R LSi-N←SiLR (1) [L=PhC(NtBu) ; R =NTMS , R =NTMS]. Compound 1 is synthesized by reacting LSi(I)-Si L with 3.1 equivalents of Me SiN at low temperature to afford a triene-like structural framework. Whereas the reaction of the LSi(I)-Si L with 2.1 equivalents of Me SiN at room temperature produced silaimine 2 with a central four-membered Si N ring which is accompanied by a silylene LSi and a cleaved silylene fragment. 1 further reacts with AgOTf at room temperature to yield compound 3 which shows coordination of nitrene to silver with the triflate salt. The compounds 1 and 2 were fully characterized by NMR, mass spectrometry, and X-ray crystallographic analysis. The quantum mechanical calculations reveal that compounds 1 and 2 have dicoordinated monovalent N atoms having two active lone pairs of electrons. These lone pairs are stabilized by hyperconjugative interactions.

Coupling of single nanodiamonds hosting SiV color centers to plasmonic double bowtie microantennas.

Color centers are promising single-photon emitters owing to their operation at room temperature and high photostability. In particular, using nanodiamonds as a host material is of interest for sensing and metrology. Furthermore, being a solid-state system allows for incorporation to photonic systems to tune both the emission intensity and photoluminescence spectrum and therefore adapt the individual color center to desired properties.

A room temperature rechargeable Li-LiNO battery with high capacity.

Lithium-ion batteries (LIBs) have become advanced energy storage technologies; however, specific capacity remains limited by the active materials in cathodes. Here, we report Li-LiNO batteries (LNBs) where LiNO in electrolyte serves as both active materials and ion conductor at room temperature. LNBs operate on a highly reversible redox between NO and NO, which results in an impressive areal capacity of 19 mAh cm at a plateau voltage of 1.

Selective Hydrogen Isotope Exchange Catalysed by Simple Alkali-Metal Bases in DMSO.

Angew Chem Int Ed Engl

January 2025

Universitat Bern, Department of Chemistry and Biochemistry, Freiestrasse 3, 3012, Bern, SWITZERLAND.

Isotope Exchange processes are becoming the preferred way to prepare isotopically labelled molecules, avoiding the redesign of multistep synthetic protocols. In the case of deuterium incorporation, the most used strategy has employed transition metals, that offer high reactivity under mild reaction conditions. Despite their success, the trade-off is that these metals are precious, and often exhibit high toxicity.

Physics-Based Synthetic Data Model for Automated Segmentation in Catalysis Microscopy.

Microsc Microanal

January 2025

Fritz-Haber-Institut der Max-Planck-Gesellschaft, Berlin 14195, Germany.

In catalysis research, the amount of microscopy data acquired when imaging dynamic processes is often too much for nonautomated quantitative analysis. Developing machine learned segmentation models is challenged by the requirement of high-quality annotated training data. We thus substitute expert-annotated data with a physics-based sequential synthetic data model.

In the field of quantum materials, understanding anomalous behavior under charge degrees of freedom through bond formation is of fundamental importance, with two key concepts: Dimerization and charge order at different cation sites. The coexistence of both dimerization and charge ordering is unusually found in NaRu2O4, even in its metallic state at room temperature. Our work unveils the origin of the interplay of these effects within metallic single-crystalline NaRu2O4.
