Nowadays, two-dimensional materials have many applications in materials science. As a novel two-dimensional layered material, MXene possesses distinct structural, electronic, and chemical properties; thus, it has potential applications in many fields, including battery electrodes, energy storage materials, sensors, and catalysts. Up to now, more than 70 MAX phases have been reported. However, in contrast to the variety of MAX phases, the existing MXene family merely includes Ti C, Ti C , (Ti , Nb ) C, (V , Cr ) C , Nb C, Ti CN, Ta C , V C, and Nb C . Among these materials, the Ti C T MXene exhibits prominently high volumetric capacitance, and the rate at which it transports electron is suitable for electrode materials in batteries and supercapacitors. Hence, Ti C T is commonly utilized as an electrode material in ion batteries such as Li , Na , K , Mg , Ca , and Al batteries. What is more, Ti C has the biggest specific surface area among all of these potential MXene phases, and therefore, Ti C has remarkably high gravimetric hydrogen storage capacities. In addition, Ti CO materials display extremely high activity for CO oxidation, which makes it possible to design catalysts for CO oxidation at low temperatures. Furthermore, Ti C T with O, OH, and/or F terminations can be used for water purification owing to excellent water permeance, favorable filtration ability, and long-time operation ability. This review supplies a relatively comprehensive summary of various applications of MXenes over the past few years.

“…The setup for phase imaging is shown in Figure 3B. It utilizes a quantitative phase microscopy technique based on QLSI [42][43][44][45]. A light-emitting diode with a wavelength centered at 617 nm integrated in a Köhler configuration is used as an illumination source with a controlled optical plane wave (controlled illuminated area and controlled numerical aperture).…”

“…The information is encoded in the phase of the transmitted light without any modulation of its intensity, making the information inaccessible with a conventional microscope. In order to resolve the encoded information, one has to obtain the phase map information, which we measured in this article using quadriwave lateral shearing interferometry (QLSI) technique [43][44][45][46] (see more details in Section 5). The phase-addressing capability of metasurfaces, i.e., the spatial phase distribution of the phase elements, can be scaled down to the single pixel with a pitch of 300 nm, which is beyond Abbe's classical diffraction limit with an incident wavelength higher than 600 nm.…”

Securing optical information to avoid counterfeiting and manipulation by unauthorized persons and agencies requires innovation and enhancement of security beyond basic intensity encryption. In this paper, we present a new method for polarization-dependent optical encryption that relies on extremely high-resolution near-field phase encoding at metasurfaces, down to the diffraction limit. Unlike previous intensity or color printing methods, which are detectable by the human eye, analog phase decoding requires specific decryption setup to achieve a higher security level. In this work, quadriwave lateral shearing interferometry is used as a phase decryption method, decrypting binary quick response (QR) phase codes and thus forming phase-contrast images, with phase values as low as 15°. Combining near-field phase imaging and far-field holographic imaging under orthogonal polarization illumination, we enhanced the security level for potential applications in the area of biometric recognition, secure ID cards, secure optical data storage, steganography, and communications.

“…To fast‐image the birefringence distribution, we propose a method to combine polarization measurement with quantitative phase microscopy (QPM). With the ability to precisely measure complex field measurements, QPM provides an efficient way to accurately retrieve structural and functional information of live cells and fabricated material structures . Recent efforts have also focused on utilizing QPM for imaging anisotropic samples.…”

Optical anisotropy measurement is essential for material characterization and biological imaging. In order to achieve single-shot mapping of the birefringence parameters of anisotropic samples, a novel polarized light imaging concept is proposed, namely quantitative polarization interference microscopy (QPIM). QPIM can be realized through designing a compact polarization-resolved interference microscopy system that captures interferograms bearing sample’s linear birefringence information. To extract the retardance and the orientation angle maps from a single-shot measurement, a mathematical model for QPIM is further developed. The QPIM system is validated by measuring a calibrated quarter-wave plate, whose fast-axis orientation angle and retardance are determined with great accuracies. The single-shot nature of QPIM further allows to measure the transient dynamics of birefringence changes in material containing anisotropic structures. This application is demonstrated by capturing transient retardance changes in a custom-designed parallel-aligned nematic liquid crystal-based device.
