Honeycomb-structured films represent an intriguing class of two-dimensional porous materials. Specifically, polyoxometalate (POM) macroanions can be introduced into these films by complexing with oppositely charged, double-tailed surfactants. Here highly-ordered honeycomb structures are reported that can be constructed by the complexes between POMs and a room temperature ionic liquid (IL1) having an imidazolium moiety in the middle and a naphthyl unit and a branched aliphatic chain at the ends. The complexes can be produced through phase transfer between an aqueous solution of POMs (typically {Mo Fe }) and a CS (or chloroform) solution of IL1. Based on the intrinsic properties of {Mo Fe } and the functional groups of the IL1, the honeycomb structures show multiple functions with bright photoluminescence and rich electrochemical properties. This work shows that by simply engineering the organic ligands involved in the POM-based inorganic-organic complexes, supramolecular structures with improved properties and wide applications can be obtained.

The search for new anode materials with high lithium-ion battery (LIB) capacity has attracted considerable attention due to the increasing need for electrical power. Here, we utilized first-principles calculations to develop a honeycomb-structured BCN monolayer, which exhibits an ultra-high Li-ion storage capacity of 2244 mA h g as an anode material for LIBs. Furthermore, the calculations show that the BCN monolayer has a comparatively small diffusion barrier of 0.

Extracellular matrix (ECM)-based small-diameter vascular grafts (SDVGs, inner diameter (ID) < 6 mm) hold great promise for clinical applications. However, existing ECM-based SDVGs suffer from limited donor availability, complex purification, high cost, and insufficient mechanical properties. SDVGs with ECM-like structure and function, and good mechanical properties were rapidly prepared by optimizing common materials and preparation, which can improve their clinical prospects.

The suitability of a range of interatomic potentials for elemental tin was evaluated in order to identify an appropriate potential for modeling the stanene (2D tin) allotropes. Structural and mechanical features of the flat (F), low-buckled (LB), high-buckled (HB), full dumbbell (FD), trigonal dumbbell (TD), honeycomb dumbbell (HD), and large honeycomb dumbbell (LHD) monolayer tin (stanene) phases, were gained by means of the density functional theory (DFT) and molecular statics (MS) calculations with ten different Tersoff, modified embedded atom method (MEAM), and machine-learning-based (ML-IAP) interatomic potentials. A systematic quantitative comparison and discussion of the results is reported.

Artificial dimension control has been playing a vital role in electronic structure manipulation and properties generation. However, systematic investigations into the dimensional regulation, such as transformation from two-dimensional (2D) materials to well-controlled one-dimensional (1D) ribbons, remain insufficient via molecular beam epitaxy. Here, high-quality ultranarrow zigzag CuTe nanoribbons are atomically precisely prepared via the dimensional regulation induced by adjusting the Te chemical potential, utilizing CuSe monolayer as the starting 2D template.

Dermatofibrosarcoma protuberans (DFSP) is a rare, locally invasive cutaneous sarcoma with a high propensity for recurrence, even following complete surgical excision. DFSP exhibits a low metastatic potential and is characterized by a distinctive honeycomb-like architecture composed of uniformly arranged spindle cells that frequently show CD34 immunostaining. Common surgical approaches include wide local excision (WLE), Mohs micrographic surgery (MMS), and, in severe cases, amputation.
