4th International Symposium on Enhanced Electrochemical Capacitors, ISEE'Cap Conference 2015
After Nantes in 2009, Poznan in 2011 and Taormina in 2013, the 4th edition of the International Symposium on Enhanced Electrochemical Capacitors, ISEE'Cap15, was held in Montpellier (France) on June 8-12 2015. The main objective of ISEE'Cap15 was to gather the most renowned international experts together with non-specialist engineers and researchers who share interest in electrochemical capacitors, including:
- Electrochemical Double Layer Capacitors, electrode materials and mechanisms
- Pseudocapacitors, electrode materials and mechanisms
- New concepts, new devices and new fabrication processes in supercapacitors
- Asymetric and hybrid devices
- Electrolytes and interfaces
- Characterization techniques, in-situ and in-operando methods
- Modelling of phenomena and systems
- Devices, system integration and applications
As for the previous events in the series, the symposium was preceded by a half-day tutorial session with four lectures given by P. Simon, W. Sugimoto, T. Brousse and J. Miller on a updated state of the art in the field.
At the 4th International Symposium on Enhanced Electrochemical Capacitors, ISEE'Cap in poster session B.Dyatkin, Drexel University (USA) presented the results of joint work describing high capacitance of coarse-grained carbide-derived carbon particles.

Most conventional supercapacitor electrode materials implement micrometer (1-10um) or nanometer (5-100 nm) size carbon particles with finely tuned porosities and high accessible specific surface areas. We present a novel internal surface area electrode with 50-100 um diameter particles, a finely tuned microporosity, a specific surface area in excess of 1800 m2/g, and high capacitive performance. We obtained these carbide-derived carbon (CDC) materials via Cl2 etching of large titanium carbide particles at 800°C and subsequently annealing them with H2 at 600ºC.
The carbon particles, which retained their coarse-grained structure, exhibited a narrow pore size distribution (dav=0.67 nm) that allowed for electrosorption of organic electrolytes and room temperature ionic liquids. Electrochemical testing using tetraethylammonium tetrafluoroborate (Net4+)(BF4-) solvated in acetonitrile showcased low ionic resistance, capacitance exceeding 120F/g (at 10mV/s), and high rate handling capability that allowed the material to store 60F/g at 1V/S charge/discharge rate.
We evaluated the performance of this carbon material using 1-ethyl-3-methylimidazolium bis(trifliuoromethylsulfonyl)imide ((EMlm+)(TFSI-)) in neat and solvated configurations. Despite the viscous nature of the electrolyte, the material displayed over 110 F/g charge storage densities in a solvent-free state and 140 F/g while solvated in acetonitrile at 10mV/s sweep rate. Furthermore, neat RTIL electrolyte extended the voltage window of the material above 3.0 V, displaying little electrochemical breakdown and improving the materials operational capability and energy density.
In addition to displaying high capacitance, dense, coare-grained carbon electrodes offer a less expensive supercapacitor fabrication approach and maximize the electrodes mass loading. We further explore the fundamental properties of his novel model system by mechanically milling or vacuum annealing the material to explore the influence of pore length and surface defects on fundamental properties of ion electrosorption in supercapacitors.

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
Congratulations to all collaborators with this interesting joint work!
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.
Here we demonstrate a new developed method for depositing Ti3C2Tx MXenes onto hydrophobic electrospun PCL membranes using oxygen plasma treatment. These novel patches hold tremendous potential for providing mechanical support to damaged heart tissue and enabling electrical signal transmission,thereby mimicking the crucial electroconductivity required for normal cardiac function. After a detailed investigation of scaffold-to-cell interplay, including electrical stimulation, novel technology has the potential for clinical application not only for cardiac regeneration, but also as neural and muscular tissue substitutes.
