We have demonstrated in our previous work that composites with general formula of 75 wt.% Ti(1-x)MoxO2-25 wt.% C (x = 0–0.2; C = traditional Black Pearls (BP) carbon) were promising supports which provided increased stability for the Pt electrocatalysts. In this study, the effect of nitrogen doping of the carbonaceous component of the composite was explored. 75 wt.% TiO2-25 wt.% carbon composite supports were prepared using graphite oxide (GO), N-doped GO and N-doped multilayer graphene. Electrocatalysts were made by loading the supports with 20 wt.% Pt. The systems were compared based on their physicochemical properties determined by low-temperature nitrogen adsorption, X-ray powder diffraction (XRD), transmission electron microscopy (TEM), X-ray photoelectron spectroscopy (XPS) and conductivity measurements. The activity of the catalysts was investigated by conventional methods in a 3-electrode electrochemical cell. The results of various characterization methods contributed to the understanding of the difference in the electrochemical properties of N-free and N-containing catalyst samples. While GO was favorable for this composite supported catalyst, its N-doping strongly influenced the growth of TiO2, forming an almost continuous coating of small TiO2 crystals. This quasi-insulating TiO2 layer between the Pt catalytic sites and the conductive part of the composite resulted in poor electrochemical activity. Mixing the sample with carbon improved its conductivity, which resulted in a significant increase in the oxygen reduction activity. © 2024 Taylor & Francis Group, LLC.}, keywords = {Graphite oxide; composite support; electrocatalyst, cyclic voltammetry (CV); N-doped graphite oxide; N-doped multilayer graphene}, year = {2024}, eissn = {1532-236X} } @article{MTMT:34873013, title = {Catalytic conversion of chitin-based biomass to nitrogen-containing chemicals}, url = {https://m2.mtmt.hu/api/publication/34873013}, author = {Ji, X. and Zhao, Y. and Lui, M.Y. and Mika, László Tamás and Chen, X.}, doi = {10.1016/j.isci.2024.109857}, journal-iso = {ISCIENCE}, journal = {ISCIENCE}, volume = {27}, unique-id = {34873013}, abstract = {The exploration of renewable alternatives to fossil fuels for chemical production is indispensable to achieve the ultimate goals of sustainable development. Chitin biomass is an abundant platform feedstock that naturally bears both nitrogen and carbon atoms to produce nitrogen-containing chemicals (including organonitrogen ones and inorganic ammonia). The expansion of biobased chemicals toward nitrogen-containing ones can elevate the economic competitiveness and benefit the biorefinery scheme. This review aims to provide an up-to-date summary on the overall advances of the chitin biorefinery for nitrogen-containing chemical production, with an emphasis on the design of the catalytic systems. Catalyst design, solvent selection, parametric effect, and reaction mechanisms have been scrutinized for different transformation strategies. Future prospectives on chitin biorefinery have also been outlined. © 2024 The Authors}, keywords = {CATALYSIS; Chemical energy}, year = {2024}, eissn = {2589-0042} } @book{MTMT:34863508, title = {Amber 2024}, url = {https://m2.mtmt.hu/api/publication/34863508}, author = {Case, D.A. and Aktulga, H.M. and Belfon, K. and Ben-Shalom, I.Y. and Berryman, J.T. and Brozell, S.R. and Cerutti, D.S. and Cheatham III, T.E. and Cisneros, G.A. and Cruzeiro, V.W.D. and Darden, T.A. and Forouzesh, N. and Giamba¸su, G. and Giese, T. and Gilson, M.K. and Gohlke, H. and Goetz, A.W. and Harris, J. and Huang, Z. and Izadi, S. and Izmailov, S.A. and Kasavajhala, K. and Kaymak, M.C. and Kolossváry, István and Kovalenko, A. and Kurtzman, T. and Lee, T.S. and Li, P. and Lin, C. and Liu, J. and Luchko, T. and Luo, R. and Machado, M. and Manathunga, M. and Merz, K.M. and Miao, Y. and Mikhailovskii, O. and Monard, G. and Nguyen, H. and O’Hearn, K.A. and Onufriev, A. and Pan, F. and Pantano, S. and Rahnamoun, A. and Roe, D.R. and Roitberg, A. and Sagui, C. and Schott-Verdugo, S. and Shajan, A. and Shen, J. and Simmerling, C.L. and Skrynnikov, N.R. and Smith, J. and Swails, J. and Walker, R.C. and Wang, J. and Wang, J. and Wu, X. and Wu, Y. and Xiong, Y. and Xue, Y. and York, D.M. and Zhao, C. and Zhu, Q. and Kollman, P.A.}, publisher = {University of California}, unique-id = {34863508}, year = {2024}, orcid-numbers = {Kolossváry, István/0000-0002-0424-4577} } @article{MTMT:34852442, title = {Flow Synthesis of Capsaicin and Capsaicinoid Analogues}, url = {https://m2.mtmt.hu/api/publication/34852442}, author = {Orosz, János Máté and Rávai, Bettina and Mátravölgyi, Béla and Bálint, Erika}, doi = {10.1021/acssuschemeng.4c01839}, journal-iso = {ACS SUSTAIN CHEM ENG}, journal = {ACS SUSTAINABLE CHEMISTRY & ENGINEERING}, volume = {12}, unique-id = {34852442}, issn = {2168-0485}, year = {2024}, eissn = {2168-0485}, pages = {7913-7923}, orcid-numbers = {Mátravölgyi, Béla/0000-0001-8782-7972; Bálint, Erika/0000-0002-5107-7089} } @article{MTMT:34846758, title = {José Elguero – an introduction and tribute}, url = {https://m2.mtmt.hu/api/publication/34846758}, author = {Hargittai, István}, doi = {10.1007/s11224-024-02334-0}, journal-iso = {STRUCT CHEM}, journal = {STRUCTURAL CHEMISTRY}, unique-id = {34846758}, issn = {1040-0400}, year = {2024}, eissn = {1572-9001} } @article{MTMT:34845147, title = {UV imaging for the rapid at-line content determination of different colourless APIs in their tablets with artificial neural networks}, url = {https://m2.mtmt.hu/api/publication/34845147}, author = {Ficzere, Máté and Mészáros, Lilla Alexandra and Diószegi, Anna and Bánrévi, Zoltán and Farkas, Attila and Lenk, Sándor and Galata, Dorián László and Nagy, Zsombor Kristóf}, doi = {10.1016/j.ijpharm.2024.124174}, journal-iso = {INT J PHARM}, journal = {INTERNATIONAL JOURNAL OF PHARMACEUTICS}, volume = {657}, unique-id = {34845147}, issn = {0378-5173}, year = {2024}, eissn = {1873-3476}, orcid-numbers = {Ficzere, Máté/0000-0002-0024-7375; Farkas, Attila/0000-0002-8877-2587; Lenk, Sándor/0000-0002-7207-0329; Galata, Dorián László/0000-0003-4760-2124} } @article{MTMT:34845070, title = {N-Functionalization of β-aminophosphonates: cytotoxic effects of the new derivatives}, url = {https://m2.mtmt.hu/api/publication/34845070}, author = {Keglevich, György and Varga, Petra Regina and Dinnyesi, Emoke and Szalai, Zsuzsanna and Bősze, Szilvia and Szabó, Rita (Oláhné) and Drahos, Laszlo and Karaghiosoff, Konstantin}, doi = {10.1039/d4ob00243a}, journal-iso = {ORG BIOMOL CHEM}, journal = {ORGANIC & BIOMOLECULAR CHEMISTRY}, volume = {22}, unique-id = {34845070}, issn = {1477-0520}, abstract = {beta-Aminophosphonates obtained by the Michael addition of primary amines to the double bond of diethyl vinylphosphonate proved to be suitable starting materials (amine components) in the Kabachnik-Fields reaction with formaldehyde and dialkyl phosphites or secondary phosphine oxides to afford N-phosphonylmethyl- and N-phosphinoylmethyl-beta-aminophosphonates.
