Summary: Molybdenum disulfide (MoS2) is a highly studied two-dimensional material due to its mechanical and chemical stability, as well as its various synthesis methods and architectures. Doping with heteroatom substituents creates active sites on the surface, enhancing gas detection and electrochemical energy storage processes. The binding energy of molecules to the MoS2 surface increases in the presence of heteroatoms, making the surfaces more sensitive to certain gases. Co-doping with foreign metals improves the electrical conductivity, distance between layers, and overall performance of MoS2-based nanomaterials in various applications. This comprehensive review provides valuable insights and guidance for researchers aiming to optimize the properties of MoS2-based nanomaterials for specific applications.

Summary: Radially conjugated carbon nanohoops, as structural models for carbon nanotube segments, have attracted significant attention from chemists. Most nanohoops currently studied consist only of benzene and simple polyaromatic hydrocarbon moieties, limiting their functional development and application. Recent research has focused on heteroatom-doped carbon nanohoops, which have shown improved optoelectronic properties and unique topological structures. The introduction of heteroatoms not only enhances their properties, but also enables regulation of their assembly, opening new possibilities for multifunctional supramolecular systems and organic materials.

Summary: The surface roughness of LPBF AlSi10Mg alloy was reduced through electrochemical polishing (ECP), with a novel viscous layer formation mechanism found during the ECP process. An intermittent electrochemical polishing (IECP) method was utilized to further improve the polishing quality. The significantly improved polishing effect of IECP was attributed to the constant removal of ECP products, enhancing the dissolution of Al element and promoting fluent dispersion of electrolyte in the metal-electrolyte interface.

Summary: The aims of this study were to investigate the value of sound touch elastography (STE) in predicting axillary lymph node metastasis (ALNM) in patients with invasive breast cancer (IBC) and to explore whether lysyl oxidase (LOX) is correlated with increasing stiffness and promotion of metastasis in IBC. The study found that STE could serve as a non-invasive method for assessing lymph node status before surgery, and the maximum stiffness value and maximum shell stiffness value could be used to predict axillary lymph node metastasis of IBC. Furthermore, the overexpression of LOX and increased collagen fiber contributed to the increased stiffness in the lesions and metastases of IBC.

Summary: A series of Co(OH)(x)(A)(y) materials with different acidic anions were synthesized and their catalytic activity for the OER was determined. Surface oxidation and the content of highly active Co(IV) were found to be crucial parameters for the OER performance. Furthermore, the leaching ability of anions in Co(OH)(x)(A)(y) was directly related to the Co(IV) content and the catalytic activity, which can be summarized as an anion leaching-metal oxidation model. This study provides deep insights into the anion effect of metal basic salt-based OER catalysts and the activation process of pre-catalysts for the OER.

Summary: In this study, ultrathin tungsten-doped hydrogenated TiO2 nanosheets were successfully synthesized and used for photocatalytic hydrogen production without the need for a noble metal cocatalyst. Tungsten doping not only modulates the bandgap and enhances solar absorption, but also introduces more oxygen vacancies and effectively improves the photothermal effect, leading to enhanced photocatalytic activity of the nanosheets. The hydrogen evolution rate of the tungsten-doped nanosheets can reach 338.79 mumol g(-1) h(-1) under full spectrum (AM 1.5G) illumination.

Summary: In this study, we demonstrate the crystalline phase induced Raman enhancement on molybdenum carbide materials (beta-Mo2C and alpha-MoC), with the Raman enhancement on beta-Mo2C being 2-4 times higher than that on alpha-MoC. Spectroscopic and theoretical calculations reveal that beta-Mo2C has a lower electron work function and a higher density of states near the Fermi level than alpha-MoC, promoting charge transfer and photo induced charge transfer processes between probe molecules and the substrate.
