Abstract

A new class of two-dimensional nanomaterials, MXenes, which are carbides/nitrides/carbonitrides of transition and refractory metals, has been critically analyzed. Since the synthesis of the first family member in 2011 by Yury Gogotsi and colleagues, MXenes have quickly become attractive for a variety of research fields due to their exceptional properties. Despite the fact that this new family of 2D materials was discovered only about ten years ago, the number of scientific publications related to MXene almost doubles every year. Thus, in 2021 alone, more than 2000 papers are expected to be published, which indicates the relevance and prospects of MXenes. The current paper critically analyzes the structural features, properties, and methods of synthesis of MXenes based on recent available research data. We demonstrate the recent trends of MXene applications in various fields, such as environmental pollution removal and water desalination, energy storage and harvesting, quantum dots, sensors, electrodes, and optical devices. We focus on the most important medical applications: photo-thermal cancer therapy, diagnostics, and antibacterial treatment. The first results on obtaining and studying the structure of high-entropy MXenes are also presented.
Keywords: MXene; two-dimensional materials; carbides; properties; selective etching

Delivering help to Ukraine from the USA, Europe, and the rest of the world!

3.jpg - 197.81 KbOur organization in Kyiv, Materials Research Center, is well aware of the needs in Ukraine now. Together with our partners, fellow Ukrainian scientists, we have organized a warehouse in Lviv, where we collect cargos and distribute them throughout Ukraine, with detailed reports confirming the delivery to the final destination, including photos of the transfer. We have transportation that can pick cargo in Poland and deliver it through a green corridor for humanitarian cargos at the Polish-Ukrainian border. 
We are ready to respond promptly, as required by the situation in Ukraine. If there are individuals, foundations or volunteer organizations willing to send help to Ukraine from Europe or the United States, we are ready to accept it in our warehouses, make collection or individual parties according to your request and pass them on to those in need. All humanitarian aid, first aid, and protective gear will be delivered to the final destination.
