🔋⚡ BioLogic will attend the 55𝐭𝐡 𝐇𝐞𝐲𝐫𝐨𝐯𝐬𝐤ý 𝐃𝐢𝐬𝐜𝐮𝐬𝐬𝐢𝐨𝐧𝐬 𝐨𝐧 𝐄𝐥𝐞𝐜𝐭𝐫𝐨𝐜𝐡𝐞𝐦𝐢𝐜𝐚𝐥 𝐈𝐦𝐩𝐞𝐝𝐚𝐧𝐜𝐞 𝐒𝐩𝐞𝐜𝐭𝐫𝐨𝐬𝐜𝐨𝐩𝐲 🔋⚡ We are proud to be participating in the 55th Heyrovský Discussions, in the Czech Republic from 9th to 13th of june. This year's theme focuses on Electrochemical Impedance Spectroscopy (EIS). EIS has become a cornerstone for researchers in electrochemistry. It offers valuable insights into electrocatalysis, corrosion, sensors, and rapidly growing fields like energy storage. At the symposium, Dr Nicolas Murer from our 𝐈𝐧𝐧𝐨𝐯𝐚𝐭𝐢𝐨𝐧 𝐚𝐧𝐝 𝐒𝐜𝐢𝐞𝐧𝐭𝐢𝐟𝐢𝐜 𝐑𝐞𝐬𝐞𝐚𝐫𝐜𝐡 𝐭𝐞𝐚𝐦 will be presenting on the topic of "𝐄𝐈𝐒 𝐨𝐧 𝐭𝐢𝐦𝐞-𝐯𝐚𝐫𝐢𝐚𝐧𝐭 𝐬𝐲𝐬𝐭𝐞𝐦𝐬: 𝐭𝐡𝐞 𝐜𝐚𝐬𝐞 𝐨𝐟 𝐭𝐡𝐞 𝐕𝐨𝐥𝐦𝐞𝐫-𝐇𝐞𝐲𝐫𝐨𝐯𝐬𝐤ý 𝐜𝐨𝐫𝐫𝐨𝐬𝐢𝐨𝐧 𝐦𝐞𝐜𝐡𝐚𝐧𝐢𝐬𝐦" This presentation delves into the application of EIS for understanding time-dependent systems, exemplified by the Volmer-Heyrovský corrosion mechanism. Meet us there ! https://lnkd.in/eDy8VsRU

💡Very happy to share our recent article, published in Angewandte Chemie. This work was carried out at University of Strasbourg during my PhD in Prof. Marine Desage-El Murr's lab , which was finished by Oscar Charpentier. #OMECA_Lab We showed how the introduction of a remote metal-binding redox site on alloxazine and flavin activates their aromatic ring towards direct C–H functionalization. The utility of the method is demonstrated with the site-selective C6 functionalization of alloxazine and flavin with a CF3 group, Br or Cl, that can be further elaborated into OH and aryl for chemical diversification. It would be a great tool for making alloxazine and flavin photocatalyst. #OMECA_Lab #Unistra #AngewChem #ANR 👇

I'm excited to share my latest publication, "Structure and Non-reactive Dynamics of the Dimeric Catalytic Domain of Human Carbonic Anhydrase IX," in Elsevier's Chemical Physics Impact as a part of a special issue "Recent Trends of Physical Chemistry in India". This research uses 1 microsecond molecular dynamics (MD) simulation to compare each of the dimeric and monomeric forms of HCAIX-c in water. While the overall structures are similar, key differences were found: 1. Active Site Reorganization: The dimer shows significant changes in the lifetime of hydrogen bonded water path which is crucial for the rate-determining proton transfer step. 2. Free energy and kinetics of a distal histidine residue: Using Markov State Model (MSM), we observed differences in the stability and kinetics of key Histidine residue sidechain rotamers. Check out the full paper for more details!

Excited to share my recent publication in the International Journal of Biological Macromolecules (IF 8.2) titled "Green and Single-Step Simultaneous Composite Starch Aerogel Formation-High Bioavailability Curcumin Particle Formation." In this study, we explored impregnation of curcumin into the aerogels through supercritical carbon dioxide technology. The aim of study was to develop the bio-based delivery systems based of composite strach/chitosan aerogels to enhanced bioaccessibility of curcumin. https://lnkd.in/gxQhTDiV

Very happy to see Stephen et al.'s work now published in #JACS! As an insider, I can only stress the tremendous effort this took them. The use of Zn(OTf)2 to access the active catalyst species is my favorite finding of this paper, and organic chemists should keep this in mind when trying to develop new methodologies in the future.
Pleased to share this publication from my DPhil, which was just recently published in #JACS! The paper describes a rhodium catalyzed regio- and enantioselective ring opening of vinyl cyclopropanes using boronic acid nucleophiles. One of the interesting things we found was that an additive was necessary under certain conditions to form a useful metal-ligand complex. Thank you to my collaborators at the University of Oxford: László Balázs, Wieland Goetzke, Violeta Stojalnikova, Ke Liu, Kirsten Christensen, Harry Mackenzie and Steve Fletcher. Also, a special thanks to Darren Poole and scientists from Solvias for the helpful discussions!

As a researcher in fluid flow in porous media, I am pleased to announce that our work, titled “Anomalies of Solute Transport in Flow of Shear-Thinning Fluids in Heterogeneous Porous Media,” has been published in the 𝗣𝗵𝘆𝘀𝗶𝗰𝘀 𝗼𝗳 𝗙𝗹𝘂𝗶𝗱𝘀 𝗝𝗼𝘂𝗿𝗻𝗮𝗹 and has been recognized as an 𝗘𝗱𝗶𝘁𝗼𝗿’𝘀 𝗣𝗶𝗰𝗸. Considering the importance of correctly understanding the transport behaviour of non-Newtonian fluid flow compared to solute transport in the flow of Newtonian fluids, in this study, we developed a computational approach to evaluate and upscale the dispersion of a solute in a shear-thinning (ST) fluid in a heterogeneous porous medium. Our results indicate that the dispersivity is a non-monotonic function of the Peclet number and the shear rate, and this behaviour is pronounced by the heterogeneity of the pore space and spatial correlations between the local permeabilities. As a result, solute transport in ST fluids deviates significantly from the same phenomenon in Newtonian fluids.

John Ernest Walker (b. 1/7/1941) British chemist who won a share of the Nobel Prize for Chemistry in 1997 for his pioneering work on how the enzyme ATP synthase catalyses the formation of the "high-energy" compound adenosine triphosphate (ATP). These molecules of ATP function as a carrier of energy in all living organisms, whether simple bacteria, fungus or plant life, or higher animals and humans. ATP takes in the chemical energy released when nutrients are metabolized, and carries that energy to the various reactions that require energy. Such reactions include cell-building, the contraction of muscle fibers, or nerve signals. https://lnkd.in/eXnWJTu
