“…The vibration of Ti-C and C-C bonds cause the appearance of peak at 797 cm -1 [44]. In addition, the D (A 1g ) and G (E 2g ) bands of disordered carbon cause the appearance of 1339 and 1558 cm -1 peaks, respectively [45]. The ω1 (Eg) Raman active phonon vibration mode corresponds to the peak of 153 cm -1 [46].…”

Abstract MXene are a class of metal carbide and metal nitride materials with a two-dimensional layered structure. MXene Ti3C2Tx has the characteristics of good metal conductivity and adjustable chemical composition, which has attracted the attention of scientists. Recently, Mxene have shown strong nonlinear photonics and optoelectronic effect, which can be used to generate ultrashort pulsed laser. However, soliton molecules pulse in laser cavity based on Mxene have not been reported at present. In this article, MXene have been characterized systematically, and the nonlinear optical characters were measured. In addition, we combined MXene with taper fiber to make a saturable absorber device for an erbium-doped fiber laser. The modulation depth and saturation absorption intensity of MXene are 10.3% and 197.5 MW/cm2, respectively. Thanks to the outstanding character of MXene, a three-order soliton molecules pulse were generated in laser cavity. The center wavelength, pulse interval and spectral modulation period of soliton molecules are 1529.4 nm, 15.5 ps and 0.5 nm, respectively. The above experimental results show that MXene have broad application prospects in the fields of optical fiber communication, laser material processing and high-resolution optics.

“…Ahmad et al also proposed a Ti 3 AlC 2 -based SA for realizing Q-switched pulses in Er-doped fiber laser, where the polyvinyl alcohol composite was used as a carrier to integrate Ti 3 AlC 2 into laser cavity. [197] In 2020, Feng et al obtained 980-fs conventional solitons and 870-fs bound state solitons pulses by depositing Ti 3 C 2 T x onto a taper fiber. [198] Ma et al reported on a hybrid mode-locked fiber laser system enabled by NPR and MXene-based SA, achieving 72-fs pulse duration with 72-dB SNR.…”

Recently, 2D materials are in great demand for various applications such as optical devices, supercapacitors, sensors, and biomedicine. MXenes as a kind of novel 2D material have attracted considerable research interest due to their outstanding mechanical, thermal, electrical, and optical properties. Especially, the excellent nonlinear optical response enables them to be potential candidates for the applications in ultrafast photonics. Here, a review of MXenes synthesis, optical properties, and applications in ultrafast lasers is presented. First, aqueous acid etching and chemical vapor deposition methods for preparing MXenes are introduced, in which the storage stability and challenges of the existing synthesis techniques are also discussed. Then, the optical properties of MXenes are discussed specifically, including plasmonic properties, optical detection, photothermal effects, and ultrafast dynamics. Furthermore, the typical ultrafast pulsed lasers enabled by MXene-based saturable absorbers operated at different wavelength regions are summarized. Finally, a summary and outlook on the development of MXenes is presented in the perspectives section.

“…), X is carbon and/or nitrogen, and Tx is a surface functional group (-O, -OH, etc.). [19,20] MXenes have excellent electrical conductivity because of their metallic backbone and inherit the hexagonal lattice symmetry of their parent MAX phase. [21] Many functional groups on the surface of MXenes give a large number of active sites, which provides significant potential for surface modification and exceptionally effective loading of active molecules.…”

Organoids have certain cellular composition and physiological features in common with real organs, making them promising models of organ formation, function, and diseases. However, Matrigel, the commonly used animal‐derived matrices in which they are developed, has limitations in mechanical adjustability and providing complex physicochemical signals. Here, the incorporation of Ti3C2TxMXene nanomaterial into Matrigel regulates the properties of Matrigel and exhibits satisfactory biocompatibility. The Ti3C2TxMXene Matrigel composites (MXene‐Matrigel) regulate the development of Cochlear Organoids (Cochlea‐Orgs), particularly in promoting the formation and maturation of organoid hair cells. Additionally, regenerated hair cells in MXene‐Matrigel are functional and exhibit better electrophysiological properties compared to hair cells in Matrigel. MXene‐Matrigel potentiates the amycin (mTOR) signaling pathway to promote hair cell differentiation, and mTOR signaling inhibition restrains hair cell differentiation. Moreover, MXene‐Matrigel facilitates innervation establishment between regenerated hair cells and spiral ganglion neurons (SGNs) growing from the Cochlea modiolus in a co‐culture system, as well as promotes synapse formation efficiency. The approach overcomes some limitations of the Matrigel‐dependent culture system and greatly accelerates the application of nanomaterials in organoid development and research on therapies for hearing loss.
