Abstract 

Two-dimensional (2D) materials with a thickness of a few nanometers or less can be used as single sheets due to their unique properties or as building blocks, to assemble a variety of structures. The family of two-dimensional (2D) transition metal carbides and nitrides, MXenes, has been expanding rapidly since the discovery of Ti3C2 in 2011 [1]. More than 20 different MXenes have been synthesized, and the structure and properties of numerous other MXenes have been predicted using density functional theory calculations [2]. MXenes’ versatile chemistry renders their properties tunable for a large variety of applications. Oxygen or OH terminated MXenes, such as Ti3C2O2, are promising candidates for biomedical applications [2].

Antibacterial properties of micrometer-thick titanium carbide (Ti3C2Tx) MXene membranes prepared by filtration on a   polyvinylidene fluoride (PVDF) support have been studied. The bactericidal properties of Ti3C2Tx modified membranes were tested against Escherichia coli and Bacillus subtilis.  The demonstrated antibacterial activity of MXene coated membranes against common waterborne bacteria, promotes their potential application as anti-biofouling membrane in water and wastewater treatment processes, as well as a bactericidal coating. [3] The 2D titanium carbide sheets manifest strong optical absorption in the near-infrared (NIR) around 800 nm. The performance of this material is comparable or even superior to that of state-of-the-art photoabsorption materials, including gold-based nanostructures, carbon nanomaterials, and transition-metal dichalcogenides. Preliminary studies show that the titanium carbide sheets serve as an efficient photothermal agent against tumor cells. [4]

ADVANCED SCIENCE NEWS: Yury Gogotsi was a chemist from the very beginning. He feels the excitement of scientific discovery, and cannot imagine doing anything else

Professor Yury Gogotsi, Drexel University, Philadelphia, USA

Yury Gogotsi was a chemist from the very beginning. He feels the excitement of scientific discovery, and cannot imagine doing anything else. It was love at first sight for Yury Gogotsi. 

Gogotsi feels that the greatest recent step in the field of materials science was the discovery of new 2D materials, the “building blocks of the future”. He is very enthusiastic about the use of nanotechnology to generate “new artificial materials, structures and devices from nanoscale building blocks” and the increased application of “modeling, simulation, and machine learning for solving materials science problems”, though he admits concern regarding the unknown effects that artificial intelligence will have on our future lives. He is also conscious of the energy required for computation and the importance of exploiting renewable resources to develop new technologies – ones that reduce energy consumption. “We need revolutionary discoveries here,” he says. “Evolutionary development won’t be enough.”
