In this work, reduced graphene oxide (RGO)–HKUST-1 mechanical mixtures were studied in order to reveal the effect of RGO content on the pressure tolerance of the texture and heat conductivity. HKUST-1 was obtained by two different synthesis routes. Air-dried MOF and RGO were thoroughly mixed prior to the compression. Powder XRD and Raman spectroscopy were used to characterize the response of the crystal structure, while low-temperature nitrogen adsorption was used the follow the adsorption properties of the pellets. Finally, the "flash" heat pulse method was used to assess the thermal properties. The gas adsorption isotherms revealed that the adsorption capacity decreases when RGO is added. Based on Raman and XRD results, we found that the synthesis route has an effect on multiple scales. We experimentally confirmed that evaluation of the thermal diffusivity requires a model more complex than the simple Fourier equation, due to the inherent heterogeneous structure of the material. A good approximation of the Fourier coefficient of thermal diffusivity was obtained using the parameters of the Guyer–Krumhansl equation. The heat pulse experiments also revealed possible size-dependent behavior.}, year = {2024}, eissn = {1572-8943}, orcid-numbers = {Fehér, Anna Éva/0000-0002-2366-6388; Farkas, Attila/0000-0002-8877-2587; Kovács, Róbert Sándor/0000-0001-5822-6035; Nagyné László, Krisztina/0000-0003-4499-3983} } @article{MTMT:34745108, title = {Classification of colorectal primer carcinoma from normal colon with mid‐infrared spectra}, url = {https://m2.mtmt.hu/api/publication/34745108}, author = {Borkovits, B. and Kontsek, Endre and Pesti, Adrián István and Gordon, Péter and Gergely, Szilveszter and Csabai, I. and Kiss, András and Pollner, Péter}, doi = {10.1002/cem.3542}, journal-iso = {J CHEMOMETR}, journal = {JOURNAL OF CHEMOMETRICS}, unique-id = {34745108}, issn = {0886-9383}, abstract = {In this project, we used formalin‐fixed paraffin‐embedded (FFPE) tissue samples to measure thousands of spectra per tissue core with Fourier transform mid‐infrared spectroscopy using an FT‐IR imaging system.

Manganese refines the grain of solder joints, yielding better thermomechanical properties. In present research, the microstructure of the manganese-doped alloys solidified with different technological parameters had been investigated. Sn/Ag0.3./Cu0.7 based solder alloy with three different Mn content (0.1, 0.4, 0.7% wt%) were rejlowed on a copper substrate with tempered hot plate. They were solidified with different cooling rates from 0.3 to 4.5 K/s. Cross-sections have been prepared from the solder samples and the metallographic properties of the solder samples was investigated with optical and scanning electron microscopes. The characteristic features of the samples have been compared to conventionally used SAC305 (Sn/Ag3/Cu0.5) solder alloys, solidified with the same rates of cooling. Results showed that besides the grain refinement, the Mn content might also have effect on the evolution of intermetallic layer between the substrate and the solder alloy. The IMC grains of the layer were more elongated and more spalled grains had been obsen,ed close to the layer. However, independently of the cooling rate, the microstructure of the Mn containing solder alloys remained the same. This suggests that the macroscopic properties are also expected to be less sensitive to the cooling rate of the solidification.}, keywords = {cooling rate; scanning electron microscopy; lead-free soldering; manganese doping; selective electrochemical etching}, year = {2019} } @article{MTMT:3046261, title = {Characterization of the microstructure of tin-silver lead free solder}, url = {https://m2.mtmt.hu/api/publication/3046261}, author = {Hurtony, Tamás József and Szakál, Alex and Almásy, László and Len, Adél and Kugler, Sándor and Bonyár, Attila and Gordon, Péter}, doi = {10.1016/j.jallcom.2016.02.177}, journal-iso = {J ALLOY COMPD}, journal = {JOURNAL OF ALLOYS AND COMPOUNDS}, volume = {672}, unique-id = {3046261}, issn = {0925-8388}, year = {2016}, eissn = {1873-4669}, pages = {13-19}, orcid-numbers = {Bonyár, Attila/0000-0002-6976-7846} } @inproceedings{MTMT:3029273, title = {The correlation between the mechanical and electrochemical properties of solder joints}, url = {https://m2.mtmt.hu/api/publication/3029273}, author = {Hurtony, Tamás József and Gordon, Péter}, booktitle = {38th International Spring Seminar on Electronics Technology (ISSE)}, doi = {10.1109/ISSE.2015.7247965}, unique-id = {3029273}, year = {2015}, pages = {70-74} } @inproceedings{MTMT:3029272, title = {Investigation of the wetting properties of Cu6Sn5 intermetallic compound}, url = {https://m2.mtmt.hu/api/publication/3029272}, author = {Gordon, Péter and Hurtony, Tamás József}, booktitle = {38th International Spring Seminar on Electronics Technology (ISSE)}, doi = {10.1109/ISSE.2015.7248013}, unique-id = {3029272}, year = {2015}, pages = {315-319} }
