The photocatalytic activities of the two modified membranes and their filtration performances were compared in detail. The significantly enhanced photocatalytic activity of the TiO2-Ag composite was proved using a methyl orange (MO) solution (c = 10−5 M) and a crude oil emulsion (c = 50 mg·L−1). The TiO2-Ag-coated membrane reduced the MO concentration by 87%, whereas the TiO2-modified membrane reached only a 46% decomposition. The photocatalytic reduction in the chemical oxygen demand of the emulsion was also ~50% higher using the TiO2-Ag-coated membrane compared to that of the TiO2-coated membrane. The photoluminescence measurements demonstrated a reduced electron/hole recombination, achieved by the Ag nanoparticle addition (TiO2-Ag), which also explained the enhanced photocatalytic activity. A significant improvement in the oil separation performance with the TiO2-Ag-coated membrane was also demonstrated: a substantial increase in the flux and flux recovery ratio (up to 92.4%) was achieved, together with a notable reduction in the flux decay ratio and the irreversible filtration resistance. Furthermore, the purification efficiency was also enhanced (achieving 98.5% and 99.9% COD and turbidity reductions, respectively). Contact angle, zeta potential, scanning electron microscopy (SEM), and atomic force microscopy (AFM) measurements were carried out to explain the results. SEM and AFM images revealed that on the TiO2-Ag-coated membrane, a less aggregated, more continuous, homogeneous, and smoother nanolayer was formed due to the ~50% more negative zeta potential of the TiO2-Ag nanocomposite compared to that of the TiO2. In summary, via Ag addition, a sufficiently hydrophilic, beneficially negatively charged, and homogeneous TiO2-Ag-coated PVDF membrane surface was achieved, which resulted in the presented advantageous filtration properties beyond the photocatalytic activity enhancement.}, year = {2024}, eissn = {2297-8739}, pages = {112}, orcid-numbers = {Gyulavári, Tamás/0000-0001-6103-6689; Janovák, László/0000-0002-2066-319X; Veréb, Gábor/0000-0001-9642-1851} } @{MTMT:34815488, title = {EFFECT OF MEDIA COMPOSITION ON THE MULTIPLICATION RATE OF VARIOUS SWEET POTATO GENOTYPES}, url = {https://m2.mtmt.hu/api/publication/34815488}, author = {Gideon , Adu Donyina and Monostori, B. and Arriaran Silva, E.M. and Szarvas, Adrienn and Bordé-Pavlicz, Ádám and Monostori, Tamás}, booktitle = {21st Wellmann International Scientific Conference}, unique-id = {34815488}, year = {2024}, pages = {35}, orcid-numbers = {Bordé-Pavlicz, Ádám/0000-0002-8318-4874; Monostori, Tamás/0000-0003-0543-5911} } @{MTMT:34813237, title = {Fouling mechanism in dairy wastewater ultrafiltration}, url = {https://m2.mtmt.hu/api/publication/34813237}, author = {Szpisják-Gulyás, Nikolett and Hodúr, Cecilia and Kertész, Szabolcs}, booktitle = {21st Wellmann International Scientific Conference}, unique-id = {34813237}, year = {2024}, pages = {89-90}, orcid-numbers = {Hodúr, Cecilia/0000-0002-2028-6304; Kertész, Szabolcs/0000-0001-9760-3008} } @article{MTMT:34802566, title = {Salicylic acid- and ethylene-dependent effects of the ER stress-inducer tunicamycin on the photosynthetic light reactions in tomato plants}, url = {https://m2.mtmt.hu/api/publication/34802566}, author = {Iqbal, Nadeem and Ördög, Attila and Koprivanacz, Péter and Kukri, András and Czékus, Zalán and Poór, Péter}, doi = {10.1016/j.jplph.2024.154222}, journal-iso = {J PLANT PHYSIOL}, journal = {JOURNAL OF PLANT PHYSIOLOGY}, volume = {295}, unique-id = {34802566}, issn = {0176-1617}, year = {2024}, eissn = {1618-1328}, orcid-numbers = {Ördög, Attila/0000-0002-1867-8237; Poór, Péter/0000-0002-4539-6358} } @article{MTMT:34802564, title = {Plant Protection by Tannins Depends on Defence-Related Phytohormones}, url = {https://m2.mtmt.hu/api/publication/34802564}, author = {Iqbal, Nadeem and Poór, Péter}, doi = {10.1007/s00344-024-11291-1}, journal-iso = {J PLANT GROWTH REGUL}, journal = {JOURNAL OF PLANT GROWTH REGULATION}, unique-id = {34802564}, issn = {0721-7595}, abstract = {Plants produce a wide variety of secondary metabolites to sustain and protect themselves against a wide range of stresses. Among these metabolites, tannins are one of the most abundant polyphenolic compounds, accounting for 25% of the dry weight of leaves, roots and bark of woody plants, but are also abundant in flowering and seed-producing plants. The presence of tannins in these organs serves to protect plants against herbivorous and pathogenic attack through their antidigestive and antimicrobial properties. In addition, tannins play a role in regulating plant growth and development by inhibiting the consumption of unripe fruits due to their astringency. In addition, several studies have also revealed various roles of them under environmental stresses. Tannins can be classified into condensed tannins (CTs), hydrolysable tannins (HTs) and phlorotannins. They are synthesised in plants via the acetate–malonate and shikimic acid pathways. Their accumulation is regulated by several transcription factors during normal development and under different stress conditions. Despite their multiple roles in plant life, information on the regulation of tannin metabolism by defence-related phytohormones is very limited. To cope with biotic and abiotic stresses, plant responses are regulated by defence-related phytohormones such as salicylic acid (SA), jasmonic acid (JA), ethylene (ET) and abscisic acid (ABA), which act as regulators of tannin production under adverse conditions. This review focuses on tannin production, moreover its occurrence, defence potential and regulation by phytohormones under different environmental and biotic stresses, based on the most recent and relevant data.}, year = {2024}, eissn = {1435-8107}, orcid-numbers = {Poór, Péter/0000-0002-4539-6358} } @article{MTMT:34771221, title = {Investigation of the Allelopathic Effect of Two Invasive Plant Species in Rhizotron System}, url = {https://m2.mtmt.hu/api/publication/34771221}, author = {Bakacsy, László and Kardos, Luca Viktória and Szepesi, Ágnes and Nagy, Krisztina Napsugár and Vasas, Andrea and Feigl, Gábor}, doi = {10.3390/life14040475}, journal-iso = {LIFE-BASEL}, journal = {LIFE-BASEL}, volume = {14}, unique-id = {34771221}, abstract = {A key question in plant invasion biology is why invasive plants are more competitive in their introduced habitat than in their native habitat. Studies show that invasive species exhibit allelopathy, influencing other plants by releasing chemicals. Research on allelopathy uses in vitro tests, investigating effects on seed germination and seedling development. Although soil plays a role in modifying allelopathic effects, observations with soil are rare and almost nothing is known about the root development of test plants developing in soil and the effects of allelopathic compounds on root architecture. Our study evaluates the allelopathic effects of false indigo-bush (Amorpha fruticosa L.) and common milkweed (Asclepias syriaca L.) on oilseed rape growth as a model plant. The rhizotron system was used to study the effect of morphology and root architecture. Leaf–soil mixtures at 0.5%, 1%, and 5% concentrations were used. Shoot and root development was strongly inhibited at 5%. But there was no difference between the allelopathy of the two species, and the application of lower concentrations did not show any effect, demonstrating that soil has a significant modifying effect on their allelopathy. Our results highlight that the development of roots growing in the soil is also worth investigating in connection with allelopathy, which can strengthen the ecological importance of allelochemicals during successful invasions.}, year = {2024}, eissn = {2075-1729}, orcid-numbers = {Bakacsy, László/0000-0003-2593-1795; Vasas, Andrea/0000-0002-1818-7702; Feigl, Gábor/0000-0001-6524-9147} } @{MTMT:34756640, title = {Nikkel szerves-fémkoordinációs vázszerkezetek és nikkel-oxid nanorészecskék hatásának vizsgálata aerob- és alga-baktérium iszap granulumos biológiai szennyvíztisztítási eljárások esetében}, url = {https://m2.mtmt.hu/api/publication/34756640}, author = {Kedves, Alfonz and Yavuz, Cagdas and Kedves, Orsolya and Haspel, Henrik and Kónya, Zoltán}, booktitle = {III.
