We report that the Kondo effect exerted by a magnetic ion depends on its chemical environment. A cobalt phthalocyanine molecule adsorbed on an Au111 surface exhibited no Kondo effect. Cutting away eight hydrogen atoms from the molecule with voltage pulses from a scanning tunneling microscope tip allowed the four orbitals of this molecule to chemically bond to the gold substrate. The localized spin was recovered in this artificial molecular structure, and a clear Kondo resonance was observed near the Fermi surface. We attribute the high Kondo temperature (more than 200 kelvin) to the small on-site Coulomb repulsion and the large half-width of the hybridized d-level.

The memristor is the fourth fundamental circuit element discovered after resistors, capacitors, and inductors. Although this concept has only been proposed in 1971 and confirmed in 2008, many materials with memristive properties have been found since 1962. Halide perovskites have been widely used in solar cells, and recently it has been found that they also possess good memristive properties. Different halide perovskites have been applied to memristors, including 3D organic–inorganic hybrid perovskites, 2D organic–inorganic hybrid perovskites, all‐inorganic cesium/rubidium lead halide perovskites, lead‐less and lead‐free perovskites, and halide perovskite quantum dots. Flexible and fiber‐shaped halide perovskite memristors have been fabricated. Several resistive switching mechanisms of halide perovskite memristors have been proposed, and the relationships between halide perovskite memristors and perovskite solar cells have been discussed. Based on halide perovskite memristors, light‐induced resistive switching and logic gate, high‐density and cross‐bar array data storage unit, and artificial synapse have been designed. Herein, recent advances in halide perovskite memristors are comprehensively and systematically reviewed. Finally, the current challenges and potential future directions in this field are discussed.

The Kondo effect in single dehydrogenated cobalt phthalocyanine (CoPc) molecules adsorbed on Au(111) monoatomic steps was studied with a low temperature scanning tunneling microscope. The CoPc molecules adsorbed on Au(111) monoatomic steps show two typical configurations, which can be dehydrogenated to reveal Kondo effect. Moreover, the Kondo temperatures (T(K)) measured for different molecules vary in a large range from approximately 150 to approximately 550 K, increasing monotonically with decreasing Co-Au distance. A simple model consisting of a single Co 3d(z) (2) orbital and a Au 6s orbital is considered and gives a qualitative explanation to the dependence. The large variation of T(K) is attributed to the variation of the interaction between the magnetic-active cobalt ion and the Au substrate resulted from different Co-Au distances.

The efficient intermolecular reaction of gold carbene intermediates, generated via gold-catalyzed alkyne oxidation, with indoles and anilines has been realized in aqueous media.

A quantum calibrated polarizable-charge transfer force field (QPCT) has been proposed to accurately describe the interaction dynamics of zinc-protein complexes. The parameters of the QPCT force field were calibrated by quantum chemistry calculation and capture the polarization and charge transfer effect. QPCTs are validated by molecular dynamic simulation of the hydration shell of the zinc ion, five proteins containing the most common zinc-binding sites (ZnCys2His2, ZnCys3His1, ZnCys4, Zn2Cys6), as well as protein-ligand binding energy in zinc protein MMP3. The calculated results show excellent agreement with the experimental measurement and with results from QM/MM simulation, demonstrating that QPCT is accurate enough to maintain the correct structural integrity of the zinc binding pocket and provide accurate interaction dynamics of the zinc-residue complex. The current approach can also be extended to the study of interaction dynamics of other metal-containing proteins by recalibrating the corresponding parameters to the specific complexes.

Since the breakthrough in power conversion efficiency when perovskite materials are used in planer‐type solar cells, researchers have tried to apply perovskite materials into fiber‐shaped solar cells in order to achieve higher power conversion efficiency. However, the difficulty of film fabrication on the fiber surface makes it difficult to obtain a high‐quality perovskite film layer, and to obtain a large improvement in performance. In this work, the vapor‐assisted deposition method is creatively applied in the preparation of fiber‐shaped solar cells, and realizing the purpose of growing a high‐quality perovskite film layer on the fiber substrate after some innovative changes are made to the fabrication processes. The power conversion efficiency of the finally obtained fiber‐shaped perovskite solar cell reaches 10.79%, which is currently the highest power conversion efficiency in the field of fiber‐shaped solar cells.

Platinum-catalyzed formal [5+2] and [4+2] annulations of isoxazoles with heterosubstituted alkynes enabled the atom-economical synthesis of valuable 1,3-oxazepines and 2,5-dihydropyridines, respectively. Importantly, this Pt catalysis not only led to unique reactivity dramatically divergent from that observed under Au catalysis, but also proceeded via unprecedented α-imino platinum carbene intermediates.
