The use of single molecule magnets (SMMs) as cornerstone elements in spintronics and quantum computing applications demands that magnetic bistability is retained when molecules are interfaced with solid conducting surfaces. Here, we employ synchrotron Mössbauer spectroscopy to investigate a monolayer tetrairon(III) (Fe4) SMM chemically grafted on gold substrate. At low temperature zero field, observe the pattern Fe4 molecule, indicating slow spin fluctuations compared timescale. Significant...

The photoinstability of plasmonic particles remains one remarkable obstacle before their clinical penetration as powerful contrast agents, for instance, in photoacoustic imaging. In particular, gold nanorods easily revert to nanospheres and so lose best optical features under exposure few-nanoseconds-long laser pulses. While this issue is attracting much attention stimulating ad hoc solutions, such the addition rigid shells, biological environment may cause even more instability. For a...
Spin crossover complexes are among the most studied classes of molecular switches and have attracted considerable attention for their potential technological use as active units in multifunctional devices. A fundamental step toward practical implementation is integration macroscopic devices adopting hybrid vertical architectures. First, physical properties interest shown by these materials bulk phase to be retained once they deposited on a solid surface. Herein, we describe study inorganic...
Iron‐sulfur clusters are ancient cofactors that could have played a role in the prebiotic chemistry leading to emergence of protometabolism. Previous research has shown certain iron‐sulfur can form from prebiotically plausible components, such as cysteine‐containing oligopeptides. However, it is unclear if these survived environments. To begin exploring this possibility, we tested stability coordinated tripeptide and N‐acetyl‐L‐cysteine methyl ester variety solutions meant mimic We also...
Abstract Magnetic nanoparticles (MNPs) of spinel type iron oxide (of approximately 4 nm) mineralized inside the internal cavity a mini ferritin-type protein have been investigated by means electron magnetic resonance (EMR) spectroscopy. EMR measurements recorded at different temperatures in perpendicular and parallel configurations. The spectra interpreted using an approach based on giant spin model. We confirm quantum behavior MNPs, moreover, thermal evolution system terms population...
The spin crossover (SCO) efficiency of [57Fe(bpz)2(phen)] (where bpz = bis(pyrazol-1-yl)borohydride and phen 9,10-phenantroline) molecules deposited on gold substrates was investigated by means synchrotron Mössbauer spectroscopy. transition driven thermally, or light induced via the LIESST (light excited spin-state trapping) effect. Both sets measurements show that, once a substrate, SCO mechanism is modified with respect to in bulk phase. A correlation distribution hyperfine parameters...

Na0.67MnO2 (NMO) stands out among the layered cathode materials used for sodium batteries due to its high-capacity values, low cost, and environmental friendliness. Unfortunately, many drawbacks arise during cycling, but nanostructure tailoring doping can help mitigate them. Our aim was synthesize undoped Cu- or Fe-doped NMO samples via sol-gel route, with a different cooling step room temperature, i.e., in natural way quenching. The formation of mixture polymorphs observed, as well...
