Abstract Here I present the theory of a new hybrid paramagnetic-ferrimagnetic SiC-YiG quantum sensor. It is designed to allow sub-nanoscale single external spin sensitivity optically detected pulsed electron electron double resonance spectroscopy, using an X band pulsed EPR spectrometer and an…
Abstract First experiments like optically detected (OD) electron paramagnetic resonance (ODMR), photoluminescence detected RABI oscillations, and optical pumping (OP) assisted pulsed EPR measurements of T2 and T1 of V2 spins in bulk SiC, which were previously demonstrated on various home build EPR…
Abstract Linalool is one of the most commonly used fragrance terpenes in consumer products. While pure linalool is considered as non-allergenic because it has a very low skin sensitization potential, its autoxidation on air leads to allylic hydroperoxides that have been shown to be major skin…
Abstract Previously reported ferromagnetic triangles (NnBu4)2[Cu3(μ‐Cl)2(μ‐4‐NO2‐pz)3Cl3] (1), (PPN)2[Cu3(μ‐Cl)2(μ‐pz)3Cl3](2), (bmim)2[Cu3(μ‐Cl)2(μ‐pz)3Cl3] (3) and newly reported (PPh4)2[Cu3(μ‐Cl)2(μ‐4‐Ph‐pz)3Cl3] (4) were studied by magnetometry, Electron Paramagnetic Resonance (EPR)…
Abstract Mounting evidence supports the role of amyloidogenesis, oxidative stress, and metal dyshomeostasis in the development of neurodegenerative disorders. Parkinson's Disease is characterized by α-Synuclein (αSyn) accumulation and aggregation in brain regions, also promoted by Cu2+. αSyn is…
Abstract Mononuclear chromium(III) complexes of formula mer-[CrIIICl3(pz*H)3] (pz*H = pyrazole (pzH), and substituted pyrazoles: 3-Me-pzH, 4-Me-pzH, 4-Cl-pzH, 4-Br-pzH, 4-I-pzH) and trans-[CrIIICl2(pzH)4]Cl were synthesized from reactions of CrCl3 hydrate and pyrazole ligands and…
Regarding the article “Polyanisotropic magnetoelectric coupling in an electrically controlled molecular spin qubit” recently published in JACS, the Institute of Chemistry is pleased to inform you that the POMAM group's artwork has also been selected to appear on the front cover of JACS, Volume 141,…
Abstract Two molecular spin triangles are studied with pulsed Electron Paramagnetic Resonance (EPR) spectroscopy to assess their magnetoelectric (ME) couplings. [Fe3O(PhCOO)6(py)3]ClO4·py (Fe3) is characterized by strong Dzyaloshinskii-Moriya interactions (DMI) which induce important…
Abstract Spectral broadenings due to Dzyaloshinskii–Moriya interactions (DMI) were assessed with respect to the decoherence they induce through increased spin–spin interactions, as the role of DMI in developing magnetoelectric spin-chirality qubits is gaining recognition. The structurally related…
Abstract Copper(II) forms well-known and stable complexes with peptides having histidine at position 2 (Xxx-His) or 3 (Xxx-Zzz-His). Their properties differ considerably due to the histidine positioning. Here we report that in the hybrid motif Xxx-His-His, the Cu(II)-complexes can be switched…
Abstract It was shown that His3 of human copper transporter 1 (hCtr1) prompts the ATCUN-like Cu(II) coordination for model peptides of the hCtr1 N-terminus. Its high Cu(II) affinity is a potential driving force for the transfer of Cu(II) from extracellular Cu(II) carriers to hCtr1. Having a…
Résumé Les propriétés magnétiques des matériaux sont exploitées dans de nombreuses applications : des plus classiques, composants électromécaniques, enregistrement magnétique, aux plus élaborées et futuristes, comme la réfrigération magnétique ou l'électronique de spin. Cet article introduit a…
Abstract Two trinuclear CuII pyrazolato complexes with a Cu3(μ3-E)-core (E = O2– or OH–) and terminal nitrite ligands in two coordination modes were characterized crystallographically, spectroscopically, and electrochemically. One-electron oxidation of the μ3-O species produces a delocalized,…
Summary Thiosemicarbazones (TSCs) are a class of strong metal ion ligands, which are currently being investigated for several applications, such as anticancer treatment. In addition to these ligands only, which exert their activity upon interaction with metal ions in cells, preformed metal–TSC…
Abstract Functionalization of a methylviologen with four methyl ester substituents significantly facilitates the first two reduction steps. The easily generated radical cation shows markedly improved air stability compared to the parent methylviologen, making this derivative of interest in organic…
