Summary: In this study, the surface modification of gold nanoclusters by Cd doping was found to significantly enhance the selectivity and activity for CO2 reduction reaction. The Cd-doped Au19Cd2 NC exhibited the highest CO2RR activity reported. Density-functional theory calculations revealed that Cd doping can boost the CO2RR performance by providing energetically feasible pathways and reducing the energy barrier for CO formation.

Summary: The effects of heavy ion irradiation on the electric performance of CdZnTe crystals were investigated in this study. It was found that the irradiation introduces a damage layer dominated by donor defects, leading to the formation of an n(+)/n homojunction. The current-voltage curves follow the Schottky emission model at low irradiation fluences, but show increased leakage current due to the Poole-Frenkel effect at higher fluences. The study provides important reference data for the irradiation protection of CdZnTe devices in high-fluence applications.

Summary: The synthesis and structural characterization of long sought-after structural forms of RZnOR' alkoxides, including a roof-like trimer and ladder-type tetramer, have been reported in this study. These novel aggregates exhibit robustness in the solid state and resistance to mechanical force. The use of H-1 NMR and diffusion-order spectroscopy demonstrated the kinetically labile nature of the new RZnOR' alkoxides in solution, highlighting their potential for ligand scrambling.

Summary: Colloidal semiconductor II-VI metal chalcogenide (ME) magic-size clusters (MSCs) exhibit either a single or double optical absorption. PL-inactive CdS MSC-322 transforms into PL-active CdS MSC-328 and MSC-373 in the presence of acetic acid (HOAc). The transformation process involves monomer substitution for PC-322 to PC-328 and monomer addition for PC-328 to PC-373.

Summary: This study challenges the assumption that transformations of colloidal semiconductor magic-size clusters (MSCs) occur with only discrete, step-wise redshifts in optical absorption. With conclusive evidence provided by real-time experiments, it is revealed that the transformations can exhibit continuous and/or step-wise behavior, with some transformations following others. The findings encourage a reconsideration of absorption redshift in previous studies of binary II-VI MSCs transformations without an increase in cluster mass.

Summary: This study reports a new dynamic MOF with flexibility originating from a tailorable Mn8O38-cluster. The flexibility of the MOF is achieved through reversible changes in coordination geometry and ligand migration driven by guest exchange. The MOF exhibits subtle three-dimensional variations in response to different aromatic molecules and shows selective separation of light hydrocarbons and Freon gases.

Summary: Interfacial charge transfer on the surface of heterogeneous photocatalysts plays a crucial role in determining the efficiency of reactive oxygen species (ROS) generation and aerobic oxidation reactions. In this study, we used reticular chemistry in metal-organic frameworks (MOFs) to design a series of isostructural Ni-8-MOFs with linearly bridged bipyrazoles as organic linkers. These crystalline Ni(8)-MOFs demonstrated improved charge separation and transfer efficiency under visible-light irradiation due to the electron-accepting capacity tuning of the pyrazole-bridging units. Among them, JNU-214, which contained a benzoselenadiazole unit, exhibited the highest photocatalytic performance in the aerobic oxidation of benzylamines.

Summary: The study revealed significant differences in the accumulation of zinc and cadmium in worker ants from different colonies at the same site, with up to three-fold and six-fold differences detected. The results indicate a high level of colony-specific metal accumulation capacity in L. niger in the study area. These findings may suggest potential for incorporating between-colony variation in metal accumulation into bioindication protocols for more accurate assessments of environmental contamination.

Summary: Zn/ZSM-5 was prepared using a combinative method of steam-assisted crystallization (SAC) and hard templating, with Zn-based MOFs as sacrificial agents. The catalysts derived from MOFs showed differences in the concentration of Lewis acidic Zn2+ species and the compositions of Zn(OH)(+) and ZnO compared to impregnated Zn/ZSM-5. Using ZIF-8 as sacrificial agent led to higher concentration of Lewis acidic Zn2+ species and a higher ratio of Zn(OH)(+)-to-ZnO in Zn/ZSM-5, resulting in better performance in the methanol aromatization reaction.

Summary: In this study, a series of photochromic rare-earth complexes were synthesized using hexaazamacrocyclic ligand LN6, and the photogenerated radicals of the ligands were revealed for the first time. The complexes 1-Ln showed photochromic behavior upon 365 nm light irradiation, induced by the photo-generated radicals. Static and dynamic magnetic studies showed weak ferromagnetic interactions among DyIII ions and photogenerated LN6 radicals in 1-Dy and its irradiated product 1-Dy*. Time-dependent fluorescence measurements demonstrated the quenching dynamics of lanthanide in the photochromic process, with a high quenching efficiency in the irradiated product 1-Eu*.

Summary: We investigated the temperature-dependent variation of the best-performance field in a trinuclear 3d-4f single-molecule magnet {DyNi2} with a simple magnetic structure. A concise model was proposed to explain the origin of this anomalous phenomenon and reveal the influence of the energy structure on the field and temperature dependence of the relaxation time. The competition between relaxation processes with different tunneling splittings in the ground states and excited states under an applied magnetic field leads to the enigmatic phenomena.

Summary: Magnetically switchable molecular solids with stimuli-responsive ON/OFF characteristics hold promise for smart switches and magnetic storage. In addition to conventional spin-crossover/charge-transfer materials, peripheral chemical entities that exhibit tunability provide an alternative and promising approach for constructing magnetic multi-stable materials. Temperature-induced reversible structural phase transitions can potentially realize magnetic bistability by affecting the coordination environment of a transition-metal center.

Summary: In this study, an inverse-Hofmann-type metal-organic framework (MOF) material [Fe-II(TPPE){Au-I(CN)(2)}]I.2H(2)O.7TCE with hysteretic spin crossover (SCO) behavior was reported. The redox-active unit [Au-I(CN)(2)](-) in the material can be oxidized by I-2 and Br-2 to form [Au-III(CN)(2)X-2](-) units via single-crystal to single-crystal transformation, and then reduced to [Au-I(CN)(2)](-) by l-ascorbic acid (AA). This study provides a platform for developing multi-responsive materials by regulating the SCO behavior through successive redox reactions.

Summary: Significant progress has been made in single-molecule magnets (SMMs) in recent years, with the milestone achievement of hysteresis blocking temperature surpassing the boiling point of liquid nitrogen. Although our understanding of constructing high-performance rare-earth SMMs has improved, there are few successful SMMs reported for actinides that possess stronger spin-orbital coupling. The review summarizes the progress on actinide SMMs and examines potential future directions.

Summary: By applying a mixed-ligand strategy, the structural change from a dinuclear cluster to a one-dimensional chain was achieved while maintaining the same core structure. The hydrogen bonding between the coordinated water molecules and other species leads to the adjustment of bond lengths and angles in the coordination environment, which in turn affects the magnetic behavior.
