Summary: Deep eutectic solvents are a new class of green solvents being explored for used nuclear fuel and critical material recycling, with this paper focusing on the chemistry of rare-earth elements in these solvents. Results show that speciation is highly dependent on the choice of the hydrogen-bond donor, and different coordination environments were observed in ethylene glycol, urea, and lactic acid systems. The study also found variations in UV/vis spectra and luminescence behavior with changing solvents, suggesting different coordination geometries for Eu3+ in these systems.

Summary: Several new Ln(2+) diaza-crown complexes were synthesized by direct synthesis of LnI(2) with 1,10-dibenzyl-1,10-diaza-18-crown-6 in organic media under air-free conditions. The coordination of the ligand with Ln(2+) caused distortion of the diaza-crown structure and resulted in closer interactions between the oxygen donors in the crown ether and the Ln(2+) center. The formation of different structures led to the discovery of three isostructural 8-coordinate complexes and two separate complexes.

Summary: In this study, a terbium(iii)-bis(phthalocyaninato) neutral complex was deposited on the rutile TiO2(110) surface, and its interaction with the surface was studied using Scanning Tunneling Microscopy (STM) and X-ray Photoelectron Spectroscopy (XPS). The results showed that the TiO2 rutile surface favored the adsorption of isolated molecules in a lying down configuration, with the phthalocyanine planes tilted by about 30 degrees. Strong molecule-substrate interactions were observed, with evidence of charge transfer from the molecule to the surface.

Summary: The van der Waals chromium trihalides exhibit field-tunable, two-dimensional magnetic orders that vary with the halogen species and the number of layers. Through soft X-ray absorption and resonant inelastic X-ray scattering spectroscopy, key energy scales such as crystal field and interorbital Coulomb interactions under different ligand metal charge transfer in CrX3 have been determined for establishing a base Hamiltonian more reliably.

Summary: This study presents high-resolution absorption and laser-excited fluorescence studies of KY3F10:Er3+ core-only nanoparticles. A total of 49 crystal-field energy levels distributed among 13 multiplets of the Er3+ ion have been deduced for the C4v point group symmetry center in this material. A parametrized, single-electron crystal-field calculation demonstrates an excellent approximation to the experimental data, with optimized crystal fit parameters comparable to the bulk KY3F10:Er3+ crystal.

Summary: The observation of single-molecule magnetism in transition-metal complexes relies on the phenomenon of zero-field splitting, which arises from the interplay of spin-orbit coupling with ligand-field-induced symmetry lowering. The heavy-atom effect in high-spin cobalt(II)-halide complexes was systematically studied in this study, where the magnitude of zero-field splitting was investigated through various techniques. The role of molecular geometry, ligand-field effects, and metal-ligand covalency in controlling the magnitude of zero-field splitting in cobalt-halide complexes was revealed through interpretation of the magnetic parameters.

Summary: Anthracene decomposition in metal flux reactions provides carbon and hydrogen interstitials for product formation. Reactions of anthracene with La/Ni and Yb/Cu fluxes produced new rare earth carbide hydrides. The presence of hydrogen in LaCH (x) was confirmed by H-1 MAS-NMR, and possible hydride sites were identified through X-ray diffraction studies. Anthracene reactions in Ln/T eutectic mixtures (Ln = La, Yb; T = Ni, Cu) resulted in the formation of complex lanthanide carbide hydride phases.

Summary: This study reports the competitive magnetocaloric effect of lanthanide fluoride materials with high magnetic anisotropy. Among them, HoF3 shows a high magnetocaloric entropy change under modest applied fields at higher temperatures and has the potential for cooling for hydrogen liquefaction. Spin-polarized neutron spectroscopy indicates that its promising magnetocaloric effect is likely due to the presence of ferromagnetic fluctuations of highly anisotropic magnetic moments, while its singlet electronic ground state and low-temperature magnetic ordering lead to a decrease in its magnetocaloric performance below 4 K.

Summary: The development of quantum technologies aims to achieve exponentially faster computations, ultrahigh performance sensing, and a comprehensive understanding of many-particle quantum systems. Molecular spins have emerged as excellent candidates for qubits due to their long coherence times, tunability through chemical synthesis, and compatibility with other quantum platforms. However, integrating molecular spin qubits into quantum devices and preserving their quantum properties on surfaces remains a challenge. This study presents a versatile bottom-up approach to arrange molecular qubits as self-assembled monolayers on surfaces, demonstrating the maintenance or even enhancement of qubit properties.

Summary: In this study, the electron spin resonance (ESR) properties of a van der Waals bulk CrBr3 single crystal were investigated. Angular- and temperature-dependent experiments were conducted in the range of the critical temperature for ferromagnetic order. The results revealed a strong uniaxial magnetic anisotropy constant and the occurrence of long wavelength spin fluctuations. The findings have implications for the potential application of CrBr3 in perpendicular magnetic tunneling junctions.

Summary: Since the emergence of graphene, proposals for tunable Landau lasers in the terahertz frequency range have been made. Despite the non-equidistance of the Landau levels, a non-radiative process still persists in Landau-quantized graphene. This work demonstrates Landau emission from Dirac fermions in HgTe quantum wells, which can be tuned by both magnetic field and carrier concentration.

Summary: The synergistic interplay of different interactions in materials leads to the emergence of novel quantum phenomena. Spin-orbit and vibronic couplings usually counteract each other; however, in cubic d(1) double perovskites they coexist and give rise to spin-orbit-lattice entanglement with unquenched dynamic Jahn-Teller effect on the metal sites. The correlation of these entangled states induced by intersite interactions has not been assessed so far.

Summary: In this study, the single-molecule magnet (SMM) behavior of a series of lanthanide ions (Tb3+, Dy3+, Ho3+, Er3+, Tm3+ and Yb3+) encapsulated in zigzag carbon nanotubes (CNTs) of different diameters was investigated ab initio. The results showed that, except for Er3+ encapsulated in the (7,0) CNT, none of the investigated systems exhibited any blocking behavior. This can be attributed to the strong competition between axial and equatorial contributions to the crystal field of the encapsulated ions, resulting in weak or lack of magnetic axiality. These results provide useful theoretical guidance for the design of high-performance SMMs via modulating the crystal field of the ligand environment.

Summary: This work investigates the dynamic magnetic properties of a complex [(Cp-Ar3)(4)(Dy2Cl4K2)-Cl-III]& BULL;3.5(C7H8) synthesized using a tri-aryl-substituted cyclopentadienyl ligand (Cp-Ar3). The Dy(III)-metallocene weakly couples via K2Cl4 and exhibits slow relaxation of magnetization below 14.5 K under zero applied dc field through KD3 energy levels with an energy barrier of 136.9/133.7 cm(-1) at the Dy sites. The coordination of two chloride ions at each Dy centre leads to geometrical distortion and reduction of the single-ion axial anisotropy energy barrier.

Summary: Using Landau-level spectroscopy, the temperature dependence of the energy band gap in zirconium pentatelluride (ZrTe5) is determined. It is found that the band gap reaches E-g = (5 & PLUSMN; 1) meV at low temperatures and increases monotonically with the temperature. This implies that ZrTe5 is a weak topological insulator with noninverted ordering of electronic bands in the center of the Brillouin zone. Magnetotransport experiments show that the resistivity anomaly in ZrTe5 is not connected with the temperature dependence of the band gap.

Summary: Drug-induced liver injury (DILI) is a common cause of acute liver failure in the USA and Europe, but most cases can be recovered or prevented by discontinuing the offending drug. Recent research has found that peroxynitrite (ONOO-) can be used as a potential indicator for early diagnosis of DILI, and there is an urgent need to establish a method to detect and track peroxynitrite in DILI cases. In this study, a FRET-based nano fluorescent probe CD-N-I was developed, which showed high selectivity and sensitivity in detecting peroxynitrite. The probe successfully detected exogenous peroxynitrite in live cells and endogenous peroxynitrite in APAP-induced liver injury of HepG2 cells.
