A TiCT MXene/alginic acid-derived mesoporous carbon nanocomposite as a potential electrode material for coin-cell asymmetric supercapacitors.

In this study, we demonstrate MXene (TiCT)-based coin-cell asymmetric supercapacitor (coin-cell ASC) exhibiting high energy density and high power density along with good capacitance. We synthesized mesoporous carbon (MC) by annealing alginic acid at varying temperatures (900 °C, 1000 °C and 1100 °C). Among the prepared samples, MC-1000 exhibited a highly porous structure and a higher surface area.

MXene-Derived TiO/Starbon Nanocomposite as a Remarkable Electrode Material for Coin-Cell Symmetric Supercapacitor.

In this study, the synthesis of a MXene (TiCT)-derived TiO/starbon (M-TiO/Starbon-800 °C) nanocomposite using a facile calcination method is explored. High-temperature exposure transforms layered TiCT into rod-like TiO and starbon into amorphous carbon. The resulting M-TiO/Starbon-800 °C nanocomposite exhibits a significantly larger surface area and pore volume compared to its individual components, leading to superior electrochemical performance.

Unprecedented Multifunctionality in Novel Monophase Micro/Nanostructured Ti-Zn Alloy.

It is always challenging to integrate multiple functions into one material system. However, those materials/devices will address society's critical global challenges and technological demands if achieved with innovative design strategies and engineering. Here, one such material with a broader spectrum of desired properties appropriate for seven applications is identified and explored, and a glucose-sensing-triggered energy-storage mechanism is demonstrated.
