The morphological and chemical structure of Vortex plate anodized titanium from commercially pure (CP) Grade 2 Titanium (Ti2) is generally used in the following; non-cemented total hip replacement (THR) stem and cup Ti alloy (Ti6Al4V) with titanium plasma spray (TPS) coating; cemented THR stem Stainless steel (SS); total knee replacement (TKR) femoral component CoCrMo alloy (CoCr); cemented acetabular component from highly cross-linked ultrahigh molecular weight polyethylene (HXL); and cementless acetabular liner from ultrahigh molecular weight polyethylene (UHMWPE) (Sanatmetal, Ltd., Eger, Hungary) discs, all of which were examined. Visualization and elemental analysis were carried out by scanning electron microscopy (SEM), energy dispersive spectroscopy (EDS) and X-ray photoelectron spectroscopy (XPS). Surface roughness was determined by atomic force microscopy (AFM) and profilometry. TPS Ti presented the highest Ra value (25 ± 2 μm), followed by CoCr (535 ± 19 nm), Ti2 (227 ± 15 nm) and SS (170 ± 11 nm). The roughness measured in the HXL and UHMWPE surfaces was in the same range, 147 ± 13 nm and 144 ± 15 nm, respectively. EDS confirmed typical elements regarding the investigated prosthesis materials. XPS results supported the EDS results and revealed a high % of Ti4+ on Ti2 and TPS surfaces. The results indicate that the surfaces of prosthesis materials have significantly different features, and a detailed characterization is needed to successfully apply them in orthopedic surgery and traumatology.}, year = {2024}, eissn = {2073-4360}, orcid-numbers = {Jillek, Bertalan/0009-0002-7561-8609; Krafcsik, Olga/0000-0003-3432-8736; Turzó, Kinga Mónika/0000-0003-4133-3998} } @article{MTMT:34856915, title = {Triggered cagedSTORM microscopy}, url = {https://m2.mtmt.hu/api/publication/34856915}, author = {Bíró, Péter and Novák, Tibor and Czvik, Elvira and Mihály, József and Szikora, Szilárd and van de Linde, Sebastian and Erdélyi, Miklós}, doi = {10.1364/BOE.517480}, journal-iso = {BIOMED OPT EXPRESS}, journal = {BIOMEDICAL OPTICS EXPRESS}, volume = {15}, unique-id = {34856915}, issn = {2156-7085}, abstract = {In standard SMLM methods, the photoswitching of single fluorescent molecules and the data acquisition processes are independent, which leads to the detection of single molecule blinking events on several consecutive frames.

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} } @article{MTMT:34723819, title = {Comparison of three nanoparticle deposition techniques potentially applicable to elemental mapping by nanoparticle-enhanced laser-induced breakdown spectroscopy}, url = {https://m2.mtmt.hu/api/publication/34723819}, author = {Casian-Plaza, F.A. and Janovszky, Patrick Martin and Palásti, Dávid Jenő and Kohut, Attila and Geretovszky, Zsolt and Heszlerné Kopniczky, Judit and Schubert, Félix and Živković, S. and Galbács, Zoltán Mihály and Galbács, Gábor}, doi = {10.1016/j.apsusc.2024.159844}, journal-iso = {APPL SURF SCI}, journal = {APPLIED SURFACE SCIENCE}, volume = {657}, unique-id = {34723819}, issn = {0169-4332}, year = {2024}, eissn = {1873-5584}, orcid-numbers = {Kohut, Attila/0000-0003-4545-2943; Geretovszky, Zsolt/0000-0002-7878-9174; Schubert, Félix/0000-0001-8647-5354; Galbács, Gábor/0000-0002-1799-5329} } @article{MTMT:34723729, title = {Pulsed laser ablation of polymer-based magnetic nanocomposites for oil spill remediation}, url = {https://m2.mtmt.hu/api/publication/34723729}, author = {Gera, Tamás Bence and Kondász, Bence and Smausz Kolumbán, Tamás and Heszlerné Kopniczky, Judit and Hodovány, Szabolcs and Ajtai, Tibor and Szabó-Révész, Piroska and Ambrus, Rita and Csóka, Ildikó and Hopp, Béla}, doi = {10.1016/j.clema.2024.100235}, journal-iso = {CLEANER MATERIALS}, journal = {CLEANER MATERIALS}, volume = {11}, unique-id = {34723729}, year = {2024}, eissn = {2772-3976}, orcid-numbers = {Gera, Tamás Bence/0000-0002-0642-0423; Smausz Kolumbán, Tamás/0000-0002-5184-6124; Hopp, Béla/0000-0002-4272-7721} } @article{MTMT:34718009, title = {Conditions on feature lines of two-dimensional scalar fields and their application to planar fluid flows}, url = {https://m2.mtmt.hu/api/publication/34718009}, author = {Sándor, Balázs and Torma, Péter}, doi = {10.1016/j.physd.2024.134112}, journal-iso = {PHYSICA D: NONLINEAR PEHONOM}, journal = {PHYSICA D: NONLINEAR PHENOMENA}, volume = {461}, unique-id = {34718009}, issn = {0167-2789}, year = {2024}, eissn = {1872-8022}, orcid-numbers = {Torma, Péter/0000-0001-9282-6931} } @article{MTMT:34618837, title = {Cosmological Distance Measurement of Twelve Nearby Supernovae IIP with ROTSE-IIIb}, url = {https://m2.mtmt.hu/api/publication/34618837}, author = {Dhungana, G. and Kehoe, R. and Staten, R. and Vinkó, József and Wheeler, J.

To achieve precise photometry, we present a new image-differencing technique that is implemented for the first time on the ROTSE SN photometry pipeline. With this method, we find up to a 20% increase in the detection efficiency and significant reduction in residual rms scatter of the SN lightcurves when compared to the previous pipeline performance. We use the published optical spectra and broadband photometry of well-studied SNe IIP to establish temporal models for ejecta velocity and photospheric temperature evolution for our SNe IIP population. This study yields measurements that are competitive with other methods even when the data are limited to a single epoch during the photospheric phase of SNe IIP. Using the fully reduced ROTSE photometry and optical spectra, we apply these models to the respective photometric epochs for each SN in the ROTSE IIP sample. This facilitates the use of the Expanding Photosphere Method (EPM) to obtain distance estimates to their respective host galaxies. We then perform cosmological parameter fitting using these EPM distances, from which we measure the Hubble constant to be 72.9(-4.3)(+5.7)kms(-1)Mpc(-1) , which is consistent with the standard Lambda CDM model values derived using other independent techniques.}, year = {2024}, eissn = {0004-637X}, orcid-numbers = {Vinkó, József/0000-0001-8764-7832} } @article{MTMT:34552784, title = {The investigation of diesel soot emission using instrument combination of multi-wavelength photoacoustic spectroscopy and scanning mobility particle sizer}, url = {https://m2.mtmt.hu/api/publication/34552784}, author = {Ajtai, Tibor and Utry, Noémi and Pintér, Máté and Abdul, Rahman and Kurilla, Boldizsár and Sárossy, Gábor and Deák, László and Baladincz, Jenő and Raffai, Péter and Szabó, Gábor and Bozóki, Zoltán}, doi = {10.1038/s41598-024-52832-8}, journal-iso = {SCI REP}, journal = {SCIENTIFIC REPORTS}, volume = {14}, unique-id = {34552784}, issn = {2045-2322}, abstract = {The parallel measurements of wavelength dependent optical absorption, particle number size distribution have made by a multi wavelength photoacoustic spectrometer (4λ-PAS) and scanning mobility particle sizer (SMPS) respectively at different modes of a diesel engine using two different types of fuel. The thermal evolution of the emission was also investigated using posterior temperature treatment of emission. The bimodal size distribution of emitted particles at a set reference temperature has been observed regardless of the applied fuel at idle. However, the emitted particulate assembly had lognormal size distribution falls into the accumulation mode at all other defined engine modes and both fuel types. The total number- and volume concentration (TNC and TVC) showed retrograde tendency with the increasing torque and rpm independently of the applied fuel types. The TNC values decreased up to 50% for both fuels with engine operation changes from idle engine mode(em#1) to low engine mode(em#2). With further increase in torque and rpm of engine, the change in TNC is negligible. On the other hand, the TVC remains more or less the same for idle to low engine mode transition and increased more than 60% for high mode (em#3) transition. The Optical Absorption Coefficient (OAC) values measured at the operational wavelengths of the 4λ-PAS instrument decreased at all wavelengths with increasing rpm and torque. The wavelength dependency quantified by Aerosol Ängström Exponent (AAE) was applied here for qualitative analysis of the carbonaceous emission and showed decreased values towards the higher engine speed and torque output of the engine.

However, the PA signal is prone to changes in bulk composition, leading to relative uncertainties in measurements of up to 10%, due to the complex dependence of the sensitivity of a PA system (S) on the thermal and acoustic properties of the gas sample. A novel calibration and concentration calculation method is proposed to keep the relative accuracy of the PA measurements in the few percentages range even in case of large-scale composition variations. The main novelty of the proposed method is that it tackles the complex dependence of the PA system's sensitivity in a way that while it varies the resonance frequency of the calibration gas, it keeps the heat capacity ratio of calibration gases at a constant value. We prove that it determines the analyte's concentration with relative accuracy of about 1 %, even when the composition of the gas varies drastically. It rigorously compensates for the frequency and heat capacity ratio dependence of S and for the dependence of the half-width of the resonance curve of the PA cell on the thermal and acoustic properties of the gas. Although the reported demonstration measurements are executed in a relatively simple gas mixture, the proposed method has widespread applicability in high-precision monitoring. © 2024 The Authors}, keywords = {Sensitivity analysis; CALIBRATION; uncertainty analysis; Gases; specific heat; photoacoustic spectroscopy; Photoacoustic effect; Acoustic properties; Photoacoustic systems; Photoacoustics; Bulk compositions; Gas phase; Relative accuracy; heat capacity ratio; heat capacity ratio; Gas-phases; Composition variation; Acoustics property; Novel calibration methodology; Novel calibration methodology; Calibration gas; Calibration methodologies}, year = {2024}, eissn = {1879-0275}, orcid-numbers = {Szabó, Gábor/0000-0001-6756-4677} } @article{MTMT:34506131, title = {Peripheral thickening of the sarcomeres and pointed end elongation of the thin filaments are both promoted by SALS and its formin interaction partners}, url = {https://m2.mtmt.hu/api/publication/34506131}, author = {Farkas, Dávid and Szikora, Szilárd and Jijumon, A S and Polgár, Tamás Ferenc and Patai, Roland and Szütsné Tóth, Mónika Ágnes and Bugyi, Beáta and Gajdos, Tamás and Bíró, Péter and Novák, Tibor and Erdélyi, Miklós and Mihály, József}, doi = {10.1371/journal.pgen.1011117}, journal-iso = {PLOS GENET}, journal = {PLOS GENETICS}, volume = {20}, unique-id = {34506131}, issn = {1553-7390}, abstract = {During striated muscle development the first periodically repeated units appear in the premyofibrils, consisting of immature sarcomeres that must undergo a substantial growth both in length and width, to reach their final size. Here we report that, beyond its well established role in sarcomere elongation, the Sarcomere length short (SALS) protein is involved in Z-disc formation and peripheral growth of the sarcomeres. Our protein localization data and loss-of-function studies in the Drosophila indirect flight muscle strongly suggest that radial growth of the sarcomeres is initiated at the Z-disc. As to thin filament elongation, we used a powerful nanoscopy approach to reveal that SALS is subject to a major conformational change during sarcomere development, which might be critical to stop pointed end elongation in the adult muscles. In addition, we demonstrate that the roles of SALS in sarcomere elongation and radial growth are both dependent on formin type of actin assembly factors. Unexpectedly, when SALS is present in excess amounts, it promotes the formation of actin aggregates highly resembling the ones described in nemaline myopathy patients. Collectively, these findings helped to shed light on the complex mechanisms of SALS during the coordinated elongation and thickening of the sarcomeres, and resulted in the discovery of a potential nemaline myopathy model, suitable for the identification of genetic and small molecule inhibitors.}, year = {2024}, eissn = {1553-7404}, orcid-numbers = {Gajdos, Tamás/0000-0002-5288-4659; Novák, Tibor/0000-0003-0756-6851; Erdélyi, Miklós/0000-0002-9501-5752} }
