“…The band-gap values of the GO and MX were roughly calculated at about 3.6 and 4.7 eV, respectively. Similar results were reported by other literatures [66][67][68][69][70] and were compared in table S1 (Sup.2). Indeed, the energy needed to excite the electron from the valance band to the conduction band of the GO and MX is more than 3.6 and 4.7 eV, respectively.…”

The efficacy of two carbon-based nanomaterials, graphene oxide (GO) and Ti3C2 MXene (MX), on the radiosensitivity of the breast cancer cells (BCC) was investigated using clinical X-ray irradiation. The prepared GO and MX nanoparticles (NPs) were firstly characterized utilizing FT-IR, UV-Vis, AFM and TEM techniques and subsequently assessed in terms of their radiobiological properties. The results of the cell toxicity assay indicated that neither NPs exhibited significant cytotoxicity after 48 h incubation with BCC up to 50 µg/mL concentration without irradiation. The cell internalization results showed an approximately equivalent cellular uptake for both NPs after 6 h incubation with BCC. Our comparative studies with radiotherapy demonstrated that both NPs substantially increased cell proliferation inhibition and cell apoptosis of BCC under X-ray irradiation when compared to BCC treated with irradiation alone. Additionally, the DCFH-DA flow cytometry results and fluorescent microscopy images revealed that both NPs remarkably increased the level of intracellular reactive oxygen species (ROS) generation in BCC under X-ray irradiation. The MX nanosheets exhibited superior radiosensitization efficiency than GO under X-ray irradiation due to its higher level of intracellular ROS generation (MX = 75.2 % and GO = 65.2 %). Clonogenic cell survival assay and extracted radiobiological parameters revealed that both NPs in combination with X-ray irradiation induced more lethal damage and less sublethal damage to BCC. Generally, the obtained results demonstrate that the MX NPs, as a stronger radiosensitizer than GO, could be a promising candidate for enhancing the effectiveness of radiotherapy in breast cancer treatment.

The recent development of separators with high flexibility, high electrolyte uptake, and ionic conductivity for batteries have gained considerable attention. However, studies on composite separators with the aforementioned properties for aqueous electrolytes in Zn-ion batteries are limited. In this research, a polyacrylonitrile (PAN)/bio-based polyurethane (PU)/Ti3C2Tx MXene composite membrane was fabricated using an electrospinning technique. Ti3C2 MXene was embedded in fibers and formed a spindle-like structure. With Ti3C2Tx MXene, the electrolyte uptake and ionic conductivity reached the superior values of 2214% and 3.35 × 10−3 S cm−1, respectively. The composite membrane presented an excellent charge–discharge stability when assembled in a Zn//Zn symmetrical battery. Moreover, the developed separator exhibited a high flexibility and no dimensional and structural changes after heat treatment, which resulted in the high-performance separator for the Zn-ion battery. Overall, the PAN/bio-based PU/Ti3C2Tx MXene composite membrane can be potentially used as a high-performance separator for Zn-ion batteries.

“…Further hydrothermal treatment of the Ti 3 AlC 2 powder in an HCl/LiF mixture leads to the disappearance of most of the MAX phase diffraction peaks and the appearance of diffraction peaks at 6.7 • , 13.84 • , 24.8 • , and 34.14 • corresponding to the (002), (004), (006), and (008) planes. This indicates the transformation of the MAX phase into the corresponding Ti 3 C 2 MXene [43]. In addition, during the formation of MXene, the appearance of a non-basal diffraction peak (110) is observed at an angle different from the MAX phase.…”

The development of new electrode materials for electrochemical systems for various purposes is a significant and in-demand task of scientific research. Layered transition metal carbides and nitrides, known as MXenes, show great potential for use as electrodes in electrochemical energy storage devices operating in aqueous electrolytes. In this work, a multilayer Ti3C2Tx MXene was obtained from a Ti3AlC2 precursor and studied as the electrode material of a symmetrical supercapacitor with an aqueous LiCl electrolyte. The formation of the MXene structure was confirmed by the data from X-ray phase analysis and scanning electron microscopy. The X-ray diffraction pattern showed the disappearance of the main reflections related to the Ti3AlC2 phase and the shift of the reflection peak (002) from 9.4° to 6.7°, which indicated successful etching of the Al layers from the Ti3AlC2 precursor. At electrolyte concentrations of 1, 5, 10, and 20 M, the supercapacitors demonstrated high specific capacitances of 105, 120, 126, and 151 F·g−1 at a scan rate of 5 mV·s−1. In addition, an increase in the LiCl concentration contributed to the expansion of the potential window from 0.7 to 1 V. It was shown that the contribution of the surface capacitance to the total capacitance of the electrode is about 40% and depends little on the scan rate. In addition, the symmetrical supercapacitor with 5 M electrolyte showed good cyclic stability with capacitance retention of 88% over 10,000 cycles. The parameters of the main components of the physical processes of supercapacitors based on Ti3C2Tx were determined by the method of impedance spectroscopy.
