Abrasive wear of the material can be treated as solids affecting the detail surface it is contacting with (process of the particle friction against the detail surface). In some cases fractions can slide on a surface of contact which causes its plastic deformation or penetrate into the material’s surface and move with it cutting the material’s microvolumes. Intensity of the abrasive wear depends on the abrasive fractions hardness, sizes and shape.
On the video one can see the abrasive wear. Mechanism of the wear is microcutting. Choice of this mechanism is conditioned by the fact that while contact of the material, the equipment is manufactured of, with bulk material (coke), the wear of the material is going according to a scheme typical for this mechanism of wear.
The study was done on the immovable ring type facility::
- The ring is placed in a through with the abrasive material;
- Axial being effected by revolvings from the gear is passing through the centre of the ring and has two levers which allows to fix the two samples in the ring;
- Сoke annealed at 900°C was put into the through.
- three stresses of samples pressing to the ring.
Two samples St3 and stainless steel were tested simultaneously on the facility

Just after samples friction one started a testing, recording time and mass of the wear. In this experiment the wear takes place by the sample rotation in the mass of abrasive particles (coke). The wear is defined by determining of linear dimensions changing.
After testing there were done graphs of the wear dependence on time, considering set conditions of the experiment. Obtained from the experiment results testify that samples of various materials under different loads show different properties. For instance, the wear resistance for St3 is increasing proportionally with increasing of pressure and is decreasing by pressure increasing.
As the designed equipment is going to operate at low pressures from the results of the experiment one can see that it is reasonable to manufacture the equipment out of St3.
MXenes potential applications include sensors, wound healing materials, and drug delivery systems. A recent study explored how different synthesis methods affect the safety and performance of MXenes. By comparing etching conditions and intercalation strategies, researchers discovered that fine-tuning the surface chemistry of MXenes plays a crucial role in improving biocompatibility. These results provide practical guidelines for developing safer MXenes and bring the field one step closer to real biomedical applications.

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.
Congratulations to all collaborators with this interesting joint work!
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
Dr. Oleksiy Gogotsi, director of MRC and Carbon-Ukraine, innovative companies that are among the leaders on the world MXene market, visited 2024 MRS Fall Meeting & Exhibit. together with Dr. Maksym Pogorielov, Head of Advanced Biomaterials and Biophysics Laboratory, University of Latvia.
MRC and Carbon-Ukraine team visited the 3rd International MXene conference held at Drexel University on August 5-8, 2024. Conference brought together the best reserchers and leading experts on MXene field. 
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.
