Our new collaborative research paper with research group from Drexel University on Porous Ti3AlC2 MAX phase enables efficient synthesis of Ti3C2Tx MXene:
MXenes, a large family of 2D carbides and/or nitrides, are amongthe most studied materials worldwide due to their great diversity of structuresand compositions. Their unique properties find use in several applications. Typically, they are manufactured by selective wet-chemical etching of layered MAXphase ceramics, which are produced nowadays primarily for MXene synthe-sis. However, the synthesis of MAX phases has not been changed since the time of their use in structural and high-temperature applications, and it has not been optimized for MXene manufacturing. In this study, we have optimized the synthesis of MAX phases for MXene manufacturing.
The main purpose of this study is to develop a porous Ti3AlC2MAX phase that can be easily ground into individual grains manually without time-consuming eliminating the need for drilling and intenseball-milling before MXene synthesis. Moreover, we also demonstrate the synthesis of highly porous Ti3AlC2 (about 70%) from an inexpensive titanium sponge instead of a highly pure titanium powderand explain the mechanisms of reaction sintering and formation of porous MAXphase. MXene obtained from this MAX phase, Ti3C2Tx, shows larger flake sizeand higher electrical conductivity in thin films, compared to the materials pro-duced from the costly fine titanium powder. The proposed approach may applyto the synthesis of other MAX phases as well.

The rise of the Internet of Things has spurred extensive research on integrating conductive materials into textiles to turn them into sensors, antennas, energy storage devices, and heaters. MXenes, owing to their high electrical conductivity and solution processability, offer an efficient way to add conductivity and electronic functions to textiles. Here, a versatile automated yarn dip coater tailored for producing continuously high-quality MXene-coated yarns and conducted the most comprehensive MXene-yarn dip coating study to date is developed. 
Congratulations and thank you to our collaborators from TU Wien and CEST for very interesting work and making it published! In this work, an upscalable electrochemical MXene synthesis is presented. Yields of up to 60% electrochemical MXene (EC-MXene) with no byproducts from a single exfoliation cycle are achieved.
Thank you to our collaborators for the amazing joint work recently published in Graphene and 2D Nanomaterials about MXene–silk fibroin composite films aiming to develop materials with tunable electronic and thermal properties

Together with colleagues from the University of Latvia, MRC/Carbone Ukraine, Adam Mickiewicz University, University Clinic Essen, and others, we have developed a novel concept involving the binding of antibodies to MXenes. In our research, we utilized anti-CEACAM1 antibodies to develop targeted photo-thermal therapy for melanoma (in vitro), paving the way for future in vivo studies and clinical trials. For the first time, we demonstrate the feasibility of delivering MXenes specifically targeted to melanoma cells, enabling the effective ablation of cancer cells under near-infrared (NIR) light. This new technique opens up vast potential for the application of MXenes in cancer treatment, diagnostics, drug delivery, and many other medical purposes.
