The 224th Electrochemical Society ECS Meeting was held in the heart of San Francisco, at the meeting headquarters hotel, the Hilton San Francisco (333 O’Farrell Street, San Francisco, CA 94102).
ECS bridges the gaps among academia, research, and engineering—bringing together scientists from around the world for the exchange of technical information. This unique blend provides an unparalleled forum for the integration of these areas of science and technology.
This major international conference at the Hilton San Francisco included more than 50 topical symposia consisting of over 2,800 technical presentations, and feature the third international ECS Electrochemical Energy Summit (E2S), which is fast becoming a tradition at ECS meetings. 2S and ECS Short Courses help launch the meeting on Sunday, October 27.
Two days of special events were devoted to E2S, with a featured symposium that explored the energy– water nexus, the intersection of two critical resource issues. Events on Sunday included an afternoon program with three invited speakers, all experts in energy issues, along with a dynamic Energy Research Group Showcase, a Poster Session, and a reception. E2S events on Monday were devoted to the Energy–Water Nexus Symposium (A3), and The ECS Lecture. Also at the conference was held Technical Exhibit and General Society and Poster Sessions.
On Monday, October 28, graduate research assistant from Nanomaterials group of Drexel University, Kelsey B. Hatzell, have presented at Poster Session presentation on Methods for Enhancing the Flowable Electrode Capacitance in the Electrochemical Flow Capacitor, resulting by common work of Drexel research team - Majid Beidaghi, Muhammed Boota, Christopher R Dennison, Emin Caglan Kumbur and professor Yury Gogotsi.

Abstract
In water stressed regions across the globe, the rate of abstraction from deep aquifers often exceeds the rate of recharge. This leads to water shortages that are sometimes irreversible. In order to address these water shortages, researchers are looking to the most abundant of source water present on earth, seawater. However, to transform seawater into clean drinking water requires a range of energy intensive processes. Such processes include Reverse Osmosis, UV disinfection and Thermal Distillation. The most promising of these technologies is Reverse Osmosis, which can achieve 1.8 kWh/m3 in current commercial plants [1]. Nevertheless, this technology is fundamentally hindered by membrane fouling and slow water transport [2]. Thus, there has been a movement toward technologies that do not use membranes, and toward technologies that remove the minority component (salt) rather than the majority component (water) [3].
Capacitive Deionization (CDI) is the process of removing ions from brackish/seawater by applying a potential between two electrodes, adsorbing ion on the surface, and producing clean water. Carbon materials are favorable as electrode materials in CDI systems because they exhibit high electric conductivity (~100 S m-1), specific surface area (up to 2000 m2 g-1), and high electrochemical stability. Herein, we report the use of spherical activated carbon beads (BET SSA 1219 m2 g-1) as the active material for electrodes for a capacitive deionization system. In a 0.15 M solution of NaCl at 10 mV s-1 the electrodes demonstrate a capacitance of 58 F/g which is on par with recently reported electrode capacitances. These results indicate that with further optimization, the spherical geometry of the particles may yield enhanced electrosorption capacity for CDI.

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.
