Summary: Molecular spins can be chemically tuned to create a robust environment for quantum information processing. The challenges in integrating molecular qubits into solid-state devices involve minimizing interaction with the substrate to reduce decoherence and controlling the spatial distribution of spins. In this study, a nanofabrication method was developed to create a 2D array of individually addressable Vanadyl Phthalocyanine (VOPc) spin qubits, with the use of a diamagnetic monolayer of Titanyl Phthalocyanine (TiOPc) as a template. This research provides a viable route for the future integration of molecular spin qubits into solid-state devices.

Summary: An analytical solution is obtained for the problem of two interacting, identical but separated spin 1/2 particles in a time-dependent external magnetic field. The solution involves isolating the pseudo-qutrit subsystem from a two-qubit system. It is shown that the quantum dynamics of a pseudo-qutrit system with a magnetic dipole-dipole interaction can be accurately described using a time-dependent basis set in an adiabatic representation. The transition probabilities between energy levels in an adiabatically varying magnetic field are illustrated, showing strong dependence on time for close energy levels and entangled states.

Summary: The magnetic double deflection experiments reveal the impact of nuclear spins on electron spin coherence in isolated AlSn12 clusters, and discuss the superatomic response of nuclear spins in the endohedral cage clusters. By varying the concentration of nuclear spins in the tin cage using isotopically enriched tin samples, the study delves into hyperfine interaction, nuclear spin statistics, and spin dynamics. Furthermore, it is demonstrated that state-interference in the multistate Landau-Zener system AlSn12 explains the significant increase in spin decoherence with the presence of one or two nuclear spins in the cluster.

Summary: In this study, we report the concentration-quenching-free properties of the 406 nm emission in Pr3+-doped nanoscintillators, which is due to the large energy gap between the S-1(0) and I-1(6) states of Pr3+ ions. This work provides further understanding of the concentration quenching effect in lanthanide-doped luminescent nanomaterials and offers a new perspective for avoiding detrimental concentration quenching. Additionally, we demonstrate the potential use of Pr3+-doped nanoscintillators as anti-counterfeiting materials.

Summary: Using first-principle spin-density functional computations, the structural, magnetic, and electronic properties of Cr- and V-doped diluted magnetic semiconductors Ca1-xCrxS and Ca1-xVxSe at x = 0.25 in the B1 (NaCl) phase were investigated. The results show that Cr-doped CaZ (Z = S, Se) exhibits half-metallic character and is stable in a ferromagnetic state, while V-doped CaZ compounds display semiconductor behavior and are stable in an antiferromagnetic state. These findings suggest that Cr/V-doped CaZ (Z = S, Se) could be a promising option for spintronic applications.

Summary: The study systematically investigates the effects of Sm-doping on the crystal structure, dielectric, and magnetic properties of CeFeO3 ceramics. A giant dielectric response is observed in Ce0.5Sm0.5FeO3 compounds at room temperature, attributed to the increase in Fe2+/Fe3+ ionic contents due to charge transfer induced by Sm doping. The results suggest that a combination of ferromagnetic double-exchange interaction related to the Fe2+ ionic content and composite spin configurations of Fe3+ ions dominate the dielectric loss in Ce1-xSmxFeO3 ceramics.

Summary: Hollow MoS2 cubes and spheres were successfully synthesized using a one-step hydrothermal method with the hard template method. The hollow MoS2 cubes exhibited higher specific capacitance and energy density compared to the hollow MoS2 spheres. The symmetrical supercapacitors assembled with these hollow structures showed good performance and high capacity retention after multiple cycles. These findings suggest that controlling the pore structure and surface characteristics of MoS2 is crucial for enhancing its electrochemical properties.

Summary: The design of a solid electrolyte interphase (SEI) plays a crucial role in improving the electrochemical performance of anode materials. In this study, lithium difluoro(oxalate)borate (LiDFOB) is used as an electrolyte additive to form a protective SEI film on Li3VO4 (LVO) anodes. The addition of LiDFOB results in a dense, uniform, stable, and LiF-richer SEI, which enhances the Li-ion storage kinetics. The generated SEI also prevents further decomposition of the electrolyte and maintains the morphology of LVO anodes during charge/discharge processes. This work demonstrates the effectiveness of LiDFOB as a multi-functional additive for LiPF6 electrolytes and provides insights into SEI construction for high-performance LVO anodes.

Summary: In this study, we used density functional theory (DFT) calculations to investigate the interaction between model graphene oxide (GO) nanostructures and chlorine monoxide ClO. We aimed to understand the role of this highly oxidizing species in breaking C-C bonds and forming significant holes on GO sheets. Our results showed that C-C bonds in a single graphene oxide sheet can be broken through a simple mechanism involving the dissociation of two chemically attached ClO molecules. The formation of carbonyl groups and holes on the GO surface was also observed. This study provides important insights into the degradation of carbon nanotubes and the stability of GO during the myeloperoxidase (MPO) catalytic cycle.

Summary: In this study, the X-ray stability of five different lead halide perovskite compositions (MAPbI3, MAPbCl3, MAPbBr3, FAPbBr3, CsPbBr3) was investigated using photoelectron spectroscopy. Different degradation mechanisms and resistance to X-ray were observed depending on the crystal composition. Overall, perovskite compositions based on the MA+ cation were found to be less stable than those based on FA+ or Cs+. Metallic lead formation was most easily observed in the chloride perovskite, followed by bromide, and very little in MAPbI3. Multiple degradation processes were identified for the bromide compositions, including ion migration, formation of volatile and solid products, as well as metallic lead. CsBr was formed as a solid degradation product on the surface of CsPbBr3.

Summary: The stability of La1/3Sr2/3Fe1-xMnxO3-delta, a perovskite-type oxide, under reducing conditions is dependent on the manganese content. Increasing the manganese content leads to a decrease in stability. The behavior of iron and manganese in the oxide shows distinct differences, which can be attributed to the difference in the enthalpy of oxidation reactions. Additionally, the change in the La/Sr ratio affects the concentration of iron and manganese ions.
