MXene Materials: Effect of Synthesis on Quality, Electronic Properties and Environmental Stability of Individual Monolayer Ti3 C2 MXene Flakes (Adv. Electron. Mater. 12/2016)

Summary: This study reports the high breakdown current density in Ti3C2Tx MXene and demonstrates its high electrical conductivity and electron mobility, making it suitable for nanometer-thin interconnects. The breakdown current density of this material is comparable to other two-dimensional materials, highlighting its potential for future applications.

Summary: Through unique experimental configuration, researchers found that the pseudocapacitive charge storage in Ti3C2Tx MXenes in acid electrolytes involves proton intercalation/deintercalation, redox switching of the Ti centres, and protonation/deprotonation of oxygen functional groups. They also observed pseudocapacitive charging outside the electrochemical contact area, suggesting a fast transport of protons mechanism across the MXene surface. These findings provide new insights into the surface chemistry of MXenes.

Summary: This study demonstrates the deposition of a Ti-3 C-2 T-x thin film sensor on cellulose paper using vacuum filtration technique, followed by encapsulation with flexible PDMS to enhance sensitivity. The use of microstructured PDMS with gaussian pattern improved pressure distribution, resulting in faster response time and better sensitivity of the sensor.

Summary: In this study, Ti-doped MoS2 monolayers with ultra-high photoluminescence intensity were successfully synthesized. The photoluminescence intensity of the Ti-doped MoS2 was found to be 85 times stronger than that of the pristine MoS2. This significant enhancement can be attributed to the dopant-induced O-Ti-S units and improved interaction between the monolayer and the mica substrate.
