Herein, we demonstrate TEMPO‐mediated electrooxidation of HMF to FDCA in ElectraSyn 2.0 using inexpensive commercially available electrodes: graphite anode and stainless‐steel cathode, thereby avoiding the often cumbersome electrode preparation. Key parameters such as concentration of HMF, KOH, and catalyst loading were optimized by experimental design. Under the optimized conditions, using only a low amount of TEMPO (5 mol%), high yield and Faradaic efficiency of 96% were achieved within 2.5 hours. Moreover, since FDCA is a monomer of the bio‐based poly(ethylene furanoate), PEF, we aimed to investigate its recovery by depolymerization, which could be of paramount importance in the circular economy of the FDCA. For this, a new polar aprotic solvent, methyl sesamol (MeSesamol), was used, allowing the facile depolymerization of PEF at room temperature with high monomer yields (up to 85%), while the cosolvent MeSesamol was recycled with high efficiency (95–100%) over five reaction cycles.}, year = {2025}, eissn = {1864-564X}, orcid-numbers = {Farkas, Vajk/0000-0002-1189-0032; Kupai, József/0000-0002-4212-4517} } @article{MTMT:35198559, title = {Does cross-validation work in telling rankings apart?}, url = {https://m2.mtmt.hu/api/publication/35198559}, author = {Sziklai, Balázs and Baranyi, Máté and Héberger, Károly}, doi = {10.1007/s10100-024-00932-1}, journal-iso = {CEJOR}, journal = {CENTRAL EUROPEAN JOURNAL OF OPERATIONS RESEARCH}, unique-id = {35198559}, issn = {1435-246X}, abstract = {Although cross-validation (CV) is a standard technique in machine learning and data science, its efficacy remains largely unexplored in ranking environments. When evaluating the significance of differences, cross-validation is typically coupled with statistical testing, such as the Dietterich, Alpaydin, or Wilcoxon test. In this paper, we evaluate the power and false positive error rate of the Dietterich, Alpaydin, and Wilcoxon statistical tests combined with cross-validation each operating with folds ranging from 5 to 10, resulting in a total of 18 variants. Our testing setup utilizes a ranking framework, similar to the Sum of Ranking Differences (SRD) statistical procedure: we assume the existence of a reference ranking, and distances are measured in L_1 L 1 -norm. We test the methods under artificial scenarios as well as on real data borrowed from sports and chemistry. The choice of the optimal CV test method depends on preferences related to the minimization of errors in type I and II cases, the size of the input, and anticipated patterns in the data. Among the investigated input sizes, the Wilcoxon method with eight folds proved to be the most effective, although its performance in type I situations is subpar. While the Dietterich and Alpaydin methods excel in type I situations, they perform poorly in type II scenarios. The inadequate performances of these tests raises questions about their efficacy outside of ranking environments too.}, year = {2025}, eissn = {1613-9178}, orcid-numbers = {Sziklai, Balázs/0000-0002-0068-8920; Baranyi, Máté/0000-0003-4415-4805} } @article{MTMT:35453271, title = {Stability enhancement of molybdenum modified rutile – carbon composite supported platinum electrocatalysts by reductive pretreatment: Surface characteristics and advanced electrocatalytic properties}, url = {https://m2.mtmt.hu/api/publication/35453271}, author = {Maria Cristina, Silva Cisneros and Borbáth, Irina and Dodony, Erzsébet and Olasz, Dániel and Sáfrán, György and Szegedi, Ágnes and Zelenka, Kristóf and Tompos, András and Pászti, Zoltán}, doi = {10.1016/j.materresbull.2024.113114}, journal-iso = {MATER RES BULL}, journal = {MATERIALS RESEARCH BULLETIN}, volume = {182}, unique-id = {35453271}, issn = {0025-5408}, abstract = {Development of strong metal-support interaction (SMSI) and its influence on the catalytic performance of the Pt/Ti0.8Mo0.2O2-C system, a representative of the mixed oxide-carbon composite supported Pt electrocatalyst family, were investigated.

TEM elemental mapping confirmed the widespread formation of Pt-oxide-C triple junctions in all catalysts.

Nevertheless, the sulfur based battery chemistry has downsides in terms of the low electronic conductivity, polysulfide shuttle effect, and low active material utilization. Currently, there are several strategies available to suppress LiPS shuttling and thereby enhance cycle life behavior of the Li-S battery. However, there is no existing literature on the use of organosulfur-based copolymer as a cathode additive material in Li-S. Herein, we have investigated the feasibility of organosulfur copolymer synthesized using sulfur, fresh and used cooking (sunflower) oil. The developed polymers were used cathode additives. The results reveal that the copolymer developed by used cooking oil-loaded cathode (poly-S-UCO@SC) delivers high specific discharge capacity of 936mAh/g at 0.05C-rate and the copolymer developed by fresh sunflower oil loaded cathode (poly-S-SF@SC) exhibits 828mAh/g. However, the poly-S-UCO@SC exhibited poor structural stability, continuous cathode degradation and poor electrochemical performances than poly-S-SF@SC. The poly-S-SF@SC showed improved polysulfide conversion, reduced shuttle effect, reversible redox process, 66.5 % capacity retention for 40 cycles with stable cycling stability and shows much potential as a suitable cathode additive material compared to poly-S-UCO.
