“…[ 51,154 ] Among the emerging 2D layered materials beyond graphene, BP has been attracted extensively interest for its great potential in electronics and optoelectronics, due to its high carrier mobility, p‐type conducting, tunable direct bandgap and unique anisotropic property. [ 26,155–201 ] The unique properties of 2D layered BP are attributed to its geometric and electronic structures. Figure a [ 40 ] shows the schematic atomic structure of BP in 3D view, top view and side view.…”

The emerging monoelemental 2D materials named as Xenes including borophene, silicene, germanene, stanene, phosphorene, arsenene, antimonene, bisthumene, selenene, and tellurene, have attracted rising attention experimentally and theoretically. Because of their excellent and versatile physical, chemical, electrical, and optical advantages, Xenes have been shown or have been predicted to have excellent performance in nanotechnology applications, addressing challenges and advances in electronics, energy, healthcare, and environment. In this review, the basic fundamentals in the classification of the periodic table group and the synthesis methods for the emerging materials are summarized. Then, the hybridization, doping and functionalization of 2D Xenes, and their corresponding applications are presented. Furthermore, a summary of research progress on 2D Xenes and the challenges and perspectives for their further development are discussed.

“…For example Tang et al have shown that a decrease of the pulse duration from 1 ps to 100 fs can result to a decrease of the nonlinear absorption coefficient of black phosphorus dispersions by about one order of magnitude. 45 The giant nonlinear absorption obtained for the annealed Sb 2 Te 3 thin films is among the highest ever reported. A detailed comparison and discussion of these nonlinear optical absorption efficiencies with current state-of-the-art materials such as other chalcogenides, 46,47 perovskites, [48][49][50] graphene, 51,52 carbon nanotubes 53 and 2D α-Mo 2 C 54 has been carried out by our group in Reference 16 (see Table 1 therein).…”

2D materials are currently very promising candidates for various photonic applications. Optimizing their optical nonlinearities requires a thorough adjustment of several properties including the film thickness. In this work thin Sb2Te3 layers with different thicknesses (ranging from 2.5 to 50 nm) are prepared by the electron beam deposition technique, and then they are properly annealed in order to achieve significant third order nonlinearities. The film structure and morphology are extensively studied by means of X-ray diffraction, scanning electron microscopy, transmission electron microscopy and energy-dispersive X-ray spectroscopy. The presence of nanocrystals with sizes highly depending on the film thickness has been observed. Optical studies are carried out by Vis–NIR spectrophotometric studies. Finally, a thickness dependent study of the ultrafast third order nonlinear optical properties of the Sb2Te3 thin films is performed. This study is carried out by means of the Z-scan technique, employing 400 fs laser pulses at 1030 nm. The observed optical nonlinearities are very high, compared with those of state-of-the-art nonlinear optical materials. Moreover they are highly dependent on the thickness of the layers. The findings demonstrate the importance of a fine adjustment of the Sb2Te3 thickness in order to enhance its nonlinear optical efficiency. They are expected to be of significant importance for mode-locking of laser systems and super-resolved direct laser writing.

“…Although bulk BP was first synthesized more than 100 years ago, thin‐film BP was not discovered until 2014. [ 51 ] Due to its excellent properties that are similar to graphene, BP has recently attracted tremendous attention for a variety of applications, especially in optoelectronics [ 52–58 ] and biomedicine, such as photothermal therapy (PTT), [ 59–63 ] photodynamic therapy (PDT), [ 64–66 ] drug delivery, [ 67,68 ] and theranostics. [ 60,67 ] The antibacterial activity of BP was investigated in vitro by exposing E. coli [ 69 ] and Bacillus subtilis ( B. subtilis ) [ 70 ] under different concentrations of BP nanosheets (BPNSs).…”

Regenerative medicine has become one of the hottest research topics in medical science that provides a promising way for repairing tissue defects in the human body. Due to their excellent physicochemical properties, the application of 2D nanomaterials in regenerative medicine has gradually developed and has been attracting a wide range of research interests in recent years. In particular, graphene and its derivatives, black phosphorus, and transition metal dichalcogenides are applied in all the aspects of tissue engineering to replace or restore tissues. This review focuses on the latest advances in the application of 2D‐nanomaterial‐based hydrogels, nanosheets, or scaffolds that are engineered to repair skin, bone, and cartilage tissues. Reviews on other applications, including cardiac muscle regeneration, skeletal muscle repair, nerve regeneration, brain disease treatment, and spinal cord healing are also provided. The challenges and prospects of applications of 2D nanomaterials in regenerative medicine are discussed.
