To investigate this relationship, we employed a non-toxic heat treatment to produce reduced graphene oxide (rGO) with varying degrees of reduction, resulting in distinct surface chemistries. The physicochemical characteristics and electrochemical properties of four differently reduced GO samples and rGO/sulfur composite cathodes developed with supercritical CO2 technology were examined. Our study established a clear correlation between the specific surface area and porosity of rGO and the electrochemical performance of the corresponding rGO/sulfur composite cathodes. Notably, rGO samples reduced at 350°C (rGO350) exhibited superior discharge capacity and long-term cycling stability compared to those reduced at higher temperatures. This performance enhancement can be attributed to the combination of high surface area, porosity, and an open morphology in rGO350. These findings underscore the importance of optimizing carbon chemistry, microstructure, and cathode synthesis strategies in Li-S batteries. By effectively controlling sulfur loading and distribution within the rGO network, we can enhance active material utilization, boost electronic conductivity, and ensure the long-term stability of rGO/sulfur composite cathodes. Our research suggests that SC-CO2-assisted synthesis offers a promising approach for designing high-performance carbon/sulfur composite cathodes for Li-S batteries. This method provides a versatile platform for tailoring the rGO morphology and surface chemistry, optimizing battery performance. By carefully considering the interplay between these factors, we can unlock the full potential of Li-S batteries for various applications.}, keywords = {Surface chemistry; Thermal reduction; Supercritical CO; polysulfides; pore morphology; Li-S battery}, year = {2024}, eissn = {1873-4669}, orcid-numbers = {SHIVA SHANKAR, LAKSHMI/0000-0003-0832-4387; Nagyné László, Krisztina/0000-0003-4499-3983; Balázsi, Katalin/0000-0002-8929-9672; Czigány, Zsolt/0000-0001-6410-8801} } @CONFERENCE{MTMT:35388190, title = {Synthesis of controlled nanoscale catalysts from complex transition metal salts by quasi-intramolecular redox reactions}, url = {https://m2.mtmt.hu/api/publication/35388190}, author = {Béres, Kende Attila and Homonnay, Z and Nagyné Bereczki, Laura and Kvitek, L and Németh, P and Kótai, László}, booktitle = {ISIAME 2024, International Sympsoium on the Industrial Applications of the Mössbauer Effect}, unique-id = {35388190}, year = {2024}, pages = {C4-C4}, orcid-numbers = {Béres, Kende Attila/0000-0003-4257-0581} } @CONFERENCE{MTMT:35388120, title = {Synthesis of controlled nanoscale transition metal oxide catalysts by heat-induced quasi-intramolecular redox reactions}, url = {https://m2.mtmt.hu/api/publication/35388120}, author = {Béres, Kende Attila and Homonnay, Z and Nagyné Bereczki, Laura and Dürvanger, Zs and Czégény, Zsuzsanna and Kvitek, L and Kótai, László}, booktitle = {ICCC 2024, 45th International Conference on Coordination Chemistry Abstract Book}, unique-id = {35388120}, year = {2024}, pages = {323-323}, orcid-numbers = {Béres, Kende Attila/0000-0003-4257-0581} } @article{MTMT:35336546, title = {An Unprecedented Tridentate-Bridging Coordination Mode of Permanganate Ions: The Synthesis of an Anionic Coordination Polymer—[CoIII(NH3)6]n[(K(κ1-Cl)2(μ2,2′,2″-(κ3-O,O′,O″-MnO4)2)n∞]—Containing Potassium Central Ion and Chlorido and Permanganato Ligands}, url = {https://m2.mtmt.hu/api/publication/35336546}, author = {Kótai, László and Béres, Kende Attila and Farkas, Attila and Holló, Berta Barta and Petruševski, Vladimir M. and Homonnay, Zoltán and Trif, László and Paiva Franguelli, Fernanda and Nagyné Bereczki, Laura}, doi = {10.3390/molecules29184443}, journal-iso = {MOLECULES}, journal = {MOLECULES}, volume = {29}, unique-id = {35336546}, issn = {1420-3049}, abstract = {A unique compound (compound 1) with structural features including an unprecedented tridentate-bridging coordination mode of permanganate ions and an eight-coordinated (rhombohedral) κ1-chlorido and tridentate permanganato ligand in a potassium complex containing coordination polymer (CoIII(NH3)6]n[(K(κ1-Cl)2(μ2,2′,2″-(κ3-O,O′,O″-MnO4)2)n∞) with isolated regular octahedral hexamminecobalt(III) cation was synthesized with a yield of >90%.

Detailed spectroscopic (IR, far-IR, and Raman) studies and correlation analysis were performed to assign all vibrational modes. The existence of a resonance Raman effect of compound 1 was also observed. The thermal decomposition products at 500 °C were found to be tetragonal nano-CoMn2O4 spinel with 19–25 nm crystallite size and KCl. The decomposition intermediates formed in toluene at 110 °C showed the presence of a potassium- and chloride-containing intermediates combined into KCl during aqueous leaching, together with the formation of cobalt(II) nitrate hexahydrate.

In this study, the antipseudomonal effects and safety profiles of the furin inhibitors MI-1851 and MI-2415 were assessed. Fluorescence quenching studies suggested no relevant binding of the compounds to human serum albumin and α1-acid glycoprotein. Both inhibitors demonstrated significant antipseudomonal activity in Madin–Darby canine kidney cells, especially compound MI-1851 at very low concentrations (0.5 µM). Using non-tumorigenic porcine IPEC-J2 cells, neither of the two furin inhibitors induced cytotoxicity (CCK-8 assay) or altered significantly the intracellular (Amplex Red assay) or extracellular (DCFH-DA assay) redox status even at a concentration of 100 µM. The same assays with MI-2415 conducted on primary human hepatocytes also resulted in no changes in cell viability and oxidative stress at up to 100 µM. Microsomal and hepatocyte-based CYP3A4 activity assays showed that both inhibitors exhibited a concentration-dependent inhibition of the isoenzyme at high concentrations. In conclusion, this study indicates a good safety profile of the furin inhibitors MI-1851 and MI-2415, suggesting their applicability as antimicrobials for further in vivo investigations, despite some inhibitory effects on CYP3A4.}, year = {2024}, eissn = {2227-9059}, orcid-numbers = {Poór, Miklós/0000-0003-1425-7459; Lange, Roman W./0009-0004-7752-6403; Steinmetzer, Torsten/0000-0001-6523-4754; Jerzsele, Ákos/0000-0002-3380-0827; Adorján, András/0000-0002-2555-6123; Bajusz, Dávid/0000-0003-4277-9481} } @article{MTMT:35288223, title = {Revising the kinetics of the n-C3H7+O2 reaction: A combined experimental and computational study}, url = {https://m2.mtmt.hu/api/publication/35288223}, author = {Eskola, Arkke J. and Pekkanen, Timo T. and Salomaa, Pyry S. and Lendvay, György and Timonen, Raimo S.}, doi = {10.1016/j.proci.2024.105377}, journal-iso = {P COMBUST INST}, journal = {PROCEEDINGS OF THE COMBUSTION INSTITUTE}, volume = {40}, unique-id = {35288223}, issn = {1540-7489}, keywords = {Master equation; Transition state theory; Radical reaction kinetics; Propyl radical; Photoionization mass-spectrometer}, year = {2024}, eissn = {1873-2704}, orcid-numbers = {Lendvay, György/0000-0002-2150-0376} } @article{MTMT:35267333, title = {Kinetics of the reactions between propargylic radicals and oxygen molecules: Experiments, master-equation simulations, and reanalysis of literature data}, url = {https://m2.mtmt.hu/api/publication/35267333}, author = {Pekkanen, Timo T. and Valkai, Laszlo and Lendvay, György and Timonen, Raimo S. and Eskola, Arkke J.}, doi = {10.1016/j.combustflame.2024.113467}, journal-iso = {COMBUST FLAME}, journal = {COMBUSTION AND FLAME}, volume = {265}, unique-id = {35267333}, issn = {0010-2180}, keywords = {Reaction kinetics; Soot formation; propargyl radical; Laser-photolysis photoionization mass; Master equation modeling; Spectrometry (LP-PIMS)}, year = {2024}, eissn = {1556-2921}, orcid-numbers = {Lendvay, György/0000-0002-2150-0376} } @article{MTMT:35267332, title = {Addition and elimination reactions on the C 4 H '9 potential-energy surface: Experiments and master-equation analysis of literature data}, url = {https://m2.mtmt.hu/api/publication/35267332}, author = {Pekkanen, Timo T. and Ramu, Elli A. and Timonen, Raimo S. and Eskola, Arkke J. and Lendvay, György}, doi = {10.1016/j.proci.2024.105267}, journal-iso = {P COMBUST INST}, journal = {PROCEEDINGS OF THE COMBUSTION INSTITUTE}, volume = {40}, unique-id = {35267332}, issn = {1540-7489}, keywords = {Master equation; SPECTROMETRY; Reaction kinetics; Collisional energy transfer; Laser-photolysis photoionization mass}, year = {2024}, eissn = {1873-2704}, orcid-numbers = {Lendvay, György/0000-0002-2150-0376} }
