AI Article Synopsis

  • The title compound forms a unique crystal structure with polymeric zigzag chains consisting of three layers, extending in the [100] direction.
  • The central silver (Ag) atom is primarily coordinated by oxygen atoms from ligand molecules, with the ligands featuring a mix of ordered and disordered arrangements.
  • Interactions between the ligands include π-π stacking of their rings and hydrogen bonding, further stabilizing the three-layered structure into extended layers parallel to (010).

Article Abstract

In the crystal structure of the title compound, [Ag(3)(C(9)H(6)N(3)O(3)S)(3)(H(2)O)(2)](n), the mol-ecules are linked into three-decked polymeric zigzag chains propagating in [100]. On the middle deck, the Ag atom is five-coordinated by three O atoms from three 4-(3-pyrid-yl)pyrimidine-2-sulfonate (L) ligands, one of which lies on a mirror plane with the sulfonate group disordered over two orientations in a 1:1 ratio, and two N atoms from two L ligands, which lie on the same mirror plane. On the upper and lower decks, the Ag atom is four-coordinated by an aqua ligand, one O and two N atoms from two L ligands with the pyridyl and pyrimidine rings twisted at 19.8 (2)°. In the polymeric chain, there are π-π inter-actions between six-membered rings of L ligands from different decks with centroid-centroid distances of 3.621 (7) and 3.721 (3) Å. In the crystal, inter-molecular O-H⋯O hydrogen bonds link further these three-decked chains into layers parallel to (010).

Objective: To develop an original-mirror alignment associated deep learning algorithm for intelligent registration of three-dimensional maxillofacial point cloud data, by utilizing a dynamic graph-based registration network model (maxillofacial dynamic graph registration network, MDGR-Net), and to provide a valuable reference for digital design and analysis in clinical dental applications.

Methods: Four hundred clinical patients without significant deformities were recruited from Peking University School of Stomatology from October 2018 to October 2022. Through data augmentation, a total of 2 000 three-dimensional maxillofacial datasets were generated for training and testing the MDGR-Net algorithm.

Schlieren texture and topography induced confinement in an organic exciton-polariton laser.

Non-linearities in organic exciton-polariton microcavities represent an attractive platform for quantum devices. However, progress in this area hinges on the development of material platforms for high-performance polariton lasing, scalable and sustainable fabrication, and ultimately strategies for electrical pumping. Here, we show how introducing Schlieren texturing and a rough intra-cavity topography in a liquid crystalline conjugated polymer enables strong in-plane confinement of polaritons and drastic enhancement of the lasing properties.

Emergent superconductivity driven by Van Hove singularity in a Janus MoPS monolayer.

Two-dimensional (2D) Janus structures with the breaking of out-of-plane mirror symmetry can induce many interesting physical phenomena, and have attracted widespread attention. Herein, we propose a MoPS monolayer with mirror asymmetry, identified by first-principles structural search calculations, which demonstrates high thermodynamic and dynamic stability. Our findings reveal that Mo 4d-orbitals dominate the metallicity, significantly enhancing the density of states near the Fermi level due to Van Hove singularities (VHSs), leading to the existence of phonon-mediated superconductivity.

Metal nanocrystals synthesized in achiral environments usually exhibit no chiroptical effects. However, by placing nominally achiral nanocrystals 1.3 nm above gold films, we find giant chiroptical effects, reaching anisotropy factors as high as ≈ 0.
