Various tools such as X-ray diffraction (XRD), Raman spectroscopy, scanning electron microscopy (SEM), optical spectroscopy and X-ray photoelectron spectroscopy, were employed to assess the structural and morphological properties. Hence, the XRD profiles showed a well crystallized Bi2WO6 orthorhombic phase. The photocatalytic performance of the resulting photocatalyst was assessed by the decomposition of Rhodamine B (RhB) and methyl orange (MO) with a decomposition efficiency of 97 and 92%, along with the highest chemical oxygen demand of 82 and 79% during 120 min of illumination, respectively. The principal novelty of the present work is to focus on the changes in the crystalline structure, the morphology, and the optical and the photoelectrochemical characteristics of the Bi2WO6, by tuning the annealing temperature of the designed photocatalyst. Such physicochemical property changes in the as-prepared photocatalyst will affect in turn its photocatalytic activity toward the organic pollutant decomposition. The photocatalytic mechanism was elaborated based on electrochemical impedance spectroscopy, photocurrent analysis, photoluminescence spectroscopy, and radical trapping measurements. The overall data indicate that the superoxide O2•− and holes h+ are the principal species responsible for the pollutant photodegradation.}, year = {2024}, eissn = {1996-1944}, pages = {1029}, orcid-numbers = {El Aouni, Aicha/0000-0001-7457-4857; Arab, Madjid/0000-0002-5114-961X; Saadi, Mohamed/0000-0003-2655-0230; Haspel, Henrik/0000-0002-1362-2752; Kónya, Zoltán/0000-0002-9406-8596; BaQais, Amal/0000-0002-4896-8235} } @article{MTMT:34687262, title = {Preparation, characterization and in vitro evaluation of the antimicrobial and antitumor activity of MnOx nanoparticles}, url = {https://m2.mtmt.hu/api/publication/34687262}, author = {Rónavári, Andrea and Ochirkhuyag, Altantuya and Igaz, Nóra and Szerencsés, Bettina and Ballai, Gergő and Huliák, Ildikó and Bocz, Csenge and Kovács, Ákos and Pfeiffer, Ilona and Csontné Kiricsi, Mónika and Kónya, Zoltán}, doi = {10.1016/j.colsurfa.2024.133528}, journal-iso = {COLLOID SURFACE A}, journal = {COLLOIDS AND SURFACES A : PHYSICOCHEMICAL AND ENGINEERING ASPECTS}, volume = {688}, unique-id = {34687262}, issn = {0927-7757}, year = {2024}, eissn = {1873-4359}, orcid-numbers = {Rónavári, Andrea/0000-0001-7054-0975; Ochirkhuyag, Altantuya/0000-0001-6495-7360; Igaz, Nóra/0000-0003-1580-4397; Pfeiffer, Ilona/0000-0003-0680-7596; Csontné Kiricsi, Mónika/0000-0002-8416-2052; Kónya, Zoltán/0000-0002-9406-8596} } @article{MTMT:34646124, title = {Synergistic enhancement of CO2 hydrogenation to C5+ hydrocarbons using mixed Fe5C2 and Na-Fe3O4 catalysts: Effects of oxide/carbide ratio, proximity, and reduction}, url = {https://m2.mtmt.hu/api/publication/34646124}, author = {Najari, Sara and Saeidi, Samrand and Sápi, András and Szamosvölgyi, Ákos and Papp, Ádám and Efremova, Anastasiia and Bali, Henrik and Kónya, Zoltán}, doi = {10.1016/j.cej.2024.149787}, journal-iso = {CHEM ENG J}, journal = {CHEMICAL ENGINEERING JOURNAL}, volume = {485}, unique-id = {34646124}, issn = {1385-8947}, year = {2024}, eissn = {1873-3212}, orcid-numbers = {Sápi, András/0000-0001-6557-0731; Kónya, Zoltán/0000-0002-9406-8596} } @article{MTMT:34535462, title = {Antimicrobial and antioxidant activity of encapsulated tea polyphenols in chitosan/alginate-coated zein nanoparticles: a possible supplement against fish pathogens in aquaculture}, url = {https://m2.mtmt.hu/api/publication/34535462}, author = {Fabrikov, Dmitri and Varga, Ágnes Timea and García, María Carmen Vargas and Bélteky, Péter and Kozma, Gábor and Kónya, Zoltán and López Martínez, Josefa L. and Barroso, Fernando and Sánchez-Muros, María José}, doi = {10.1007/s11356-024-32058-x}, journal-iso = {ENVIRON SCI POLLUT R}, journal = {ENVIRONMENTAL SCIENCE AND POLLUTION RESEARCH}, volume = {31}, unique-id = {34535462}, issn = {0944-1344}, abstract = {Regulation of antibiotic use in aquaculture calls for the emergence of more sustainable alternative treatments. Tea polyphenols (GTE), particularly epigallocatechin gallate (EGCG), have various biological activities. However, tea polyphenols are susceptible to degradation. In this work, EGCG and GTE were encapsulated in zein nanoparticles (ZNP) stabilized with alginate (ALG) and chitosan (CS) to reduce the degradation effect. ALG-coated ZNP and ALG/CS-coated ZNP encapsulating EGCG or GTE were obtained with a hydrodynamic size of less than 300 nm, an absolute ζ -potential value >30 mV, and an encapsulation efficiency greater than 75%. The antioxidant capacity of the encapsulated substances, although lower than that of the free ones, maintained high levels. On the other hand, the evaluation of antimicrobial activity showed greater efficiency in terms of growth inhibition for ALG/CS-ZNP formulations, with average overall values of around 60%, reaching an inhibition of more than 90% for Photobacterium damselae . These results support encapsulation as a good strategy for tea polyphenols, as it allows maintaining significant levels of antioxidant activity and increasing the potential for antimicrobial activity, in addition to increasing protection against sources of degradation.}, year = {2024}, eissn = {1614-7499}, pages = {13673-13687}, orcid-numbers = {Fabrikov, Dmitri/0000-0001-5048-4232; Kozma, Gábor/0000-0003-2033-0720; Kónya, Zoltán/0000-0002-9406-8596} } @article{MTMT:34513997, title = {Photocatalytic and surface properties of titanium dioxide nanoparticles in soil solutions}, url = {https://m2.mtmt.hu/api/publication/34513997}, author = {Solymos, Karolina and Babcsányi, Izabella and Ariya, Badam and Gyulavári, Tamás and Ágoston, Áron and Szamosvölgyi, Ákos and Kukovecz, Ákos and Kónya, Zoltán and Farsang, Andrea and Pap, Zsolt}, doi = {10.1039/D3EN00622K}, journal-iso = {ENVIRON SCI-NANO}, journal = {ENVIRONMENTAL SCIENCE-NANO}, volume = {11}, unique-id = {34513997}, issn = {2051-8153}, abstract = {Nanotechnology has emerged as a rapidly growing scientific field with diverse applications.

It is clear that interfacial perimeter sites have outstanding skills for turning catalytic reactions over, however, high activity and selectivity of the designed interface‐induced metal distortion can also obtain catalysts for the most crucial industrial processes as evidenced in this paper. Herein, the beneficial synergy established between designed Pt nanoparticles and MnO in the course of the reverse water gas shift (RWGS) reaction resulted in a Pt/MnO catalyst having ~10 times higher activity compared to the reference Pt/SBA‐15 catalyst with >99% CO selectivity. Under activation, a crystal assembly through the metallic Pt (110) and MnO evolved, where the plane distance differences caused a mismatched row structure in softer Pt nanoparticles, which was identified by microscopic and surface‐sensitive spectroscopic characterizations combined with density functional theory simulations. The generated edge dislocations caused the Pt lattice expansion which led to the weakening of the Pt‐CO bond. Even though MnO also exhibited an adverse effect on Pt by lowering the number of exposed metal sites, rapid desorption of the linearly adsorbed CO species governed the performance of the Pt/MnO in the RWGS.}, year = {2024}, eissn = {1521-3773}, orcid-numbers = {Sápi, András/0000-0001-6557-0731; Óvári, László/0000-0001-8991-2708; Halasi, Gyula/0000-0003-0195-9400; Baán, Kornélia/0000-0001-7511-4422; Kukovecz, Ákos/0000-0003-0716-9557; Kónya, Zoltán/0000-0002-9406-8596} } @article{MTMT:34452984, title = {The neutralization of tricalcium aluminate hexahydrate and its spontaneous transformation into Friedel's salt, a layered double hydroxide}, url = {https://m2.mtmt.hu/api/publication/34452984}, author = {Kása, Eszter and Szabó, Yvette and Szabados, Márton and Kukovecz, Ákos and Kónya, Zoltán and Sipos, Pál Miklós and Kutus, Bence}, doi = {10.1016/j.cemconres.2023.107414}, journal-iso = {CEMENT CONCRETE RES}, journal = {CEMENT AND CONCRETE RESEARCH}, volume = {177}, unique-id = {34452984}, issn = {0008-8846}, year = {2024}, eissn = {1873-3948}, orcid-numbers = {Szabados, Márton/0000-0002-7588-335X; Kukovecz, Ákos/0000-0003-0716-9557; Kónya, Zoltán/0000-0002-9406-8596; Sipos, Pál Miklós/0000-0003-1407-0950; Kutus, Bence/0000-0001-5023-0152} } @article{MTMT:34353068, title = {Nickel oxide nanoparticles induce cell wall modifications, root anatomical changes, and nitrosative signaling in ecotypes of Ni hyperaccumulator Odontarrhena lesbiaca}, url = {https://m2.mtmt.hu/api/publication/34353068}, author = {Kondak, Selahattin and Janovszky, Patrick Martin and Szőllősi, Réka and Molnár, Árpád and Kondak, Dóra and Adedokun, Oluwatosin Peace and Dimitrakopoulos, Panayiotis G. and Rónavári, Andrea and Kónya, Zoltán and Erdei, László and Galbács, Gábor and Kolbert, Zsuzsanna}, doi = {10.1016/j.envpol.2023.122874}, journal-iso = {ENVIRON POLLUT}, journal = {ENVIRONMENTAL POLLUTION}, volume = {341}, unique-id = {34353068}, issn = {0269-7491}, year = {2024}, eissn = {1873-6424}, orcid-numbers = {Kondak, Selahattin/0000-0003-4979-5986; Kondak, Dóra/0000-0002-2338-6896; Adedokun, Oluwatosin Peace/0009-0005-6193-002X; Dimitrakopoulos, Panayiotis G./0000-0002-8374-4392; Rónavári, Andrea/0000-0001-7054-0975; Kónya, Zoltán/0000-0002-9406-8596; Galbács, Gábor/0000-0002-1799-5329; Kolbert, Zsuzsanna/0000-0002-7819-4672} } @article{MTMT:34353029, title = {A novel co-contaminated sediment treatment approach: Quercus petraea leaf-extracted nZVI supported on native clay and biochar for potentially toxic elements and PAHs removal}, url = {https://m2.mtmt.hu/api/publication/34353029}, author = {Slijepčević, Nataša and Rađenović, Dunja and Beljin, Jelena and Kozma, Gábor and Kónya, Zoltán and Maletić, Snežana and Tomašević Pilipović, Dragana}, doi = {10.1007/s11368-023-03682-w}, journal-iso = {J SOIL SEDIMENT}, journal = {JOURNAL OF SOILS AND SEDIMENTS}, volume = {24}, unique-id = {34353029}, issn = {1439-0108}, year = {2024}, eissn = {1614-7480}, pages = {509-524}, orcid-numbers = {Kozma, Gábor/0000-0003-2033-0720; Kónya, Zoltán/0000-0002-9406-8596} }
