Small animal PET cameras with high spatial resolution and high sensitivity are also useful, beyond their original pre-clinical application, in the following of surface chemical and the physicochemical processes. The purpose of this study was the introduction of the three-dimensional real-time PET based visualization method in separation processes. The separated tracer compounds can be followed and displayed in three dimension along chromatography column using the PET technique. We studied the separation of 11C-labeled methanol and 11C-labeled methyl iodide using reversed-phase high performance liquid chromatography (HPLC) on semi-preparative and analytical columns in order to determine the detection limits of our PET camera (MiniPET). The PET imaging is suitable for analyzing the column efficiency and the underlying processes in the liquid chromatography. Synthesis, separation and quality control of PET radiopharmaceuticals are performed in radiochemistry labs (in PET Centers) with the help of the liquid chromatography, therefore equipment, infrastructure and other lab conditions are usually available for researchers and for private companies to study chromatographic separation processes and to develop columns.}, year = {2017}, eissn = {2365-6549}, pages = {9797-9802} } @{MTMT:3284747, title = {A Cassignol-Gillot módszer bevezetése az MTA Atomki IKER Központjában}, url = {https://m2.mtmt.hu/api/publication/3284747}, author = {Benkó, Zsolt and Nagy, Dávid and Jáger, Viktor and Szepesi, János and Pécskay, Zoltán and Ott, Ulrich and Kocsisné, Pető Mária}, booktitle = {Ahol az elemek találkoznak: víz, föld és tűz határán}, unique-id = {3284747}, year = {2017}, pages = {21-24}, orcid-numbers = {Jáger, Viktor/0000-0003-1283-5198} } @article{MTMT:3227934, title = {First report of long term measurements of the MGGL laboratory in the Matra mountain range}, url = {https://m2.mtmt.hu/api/publication/3227934}, author = {Barnaföldi, Gergely Gábor and Bulik, T and Cieslar, M and Dávid, Ernő and Dobróka, Mihály and Fenyvesi, Edit and Gondek-Rosinska, D and Gráczer, Zoltán and Hamar, Gergő and Huba, G and Kis, Árpád and Kovács, Róbert Sándor and Lemperger, István and Lévai, Péter and Molnár, József and Nagy, Dávid and Novák, Attila and Oláh, László and Pázmándi, Péter and Piri, D and Somlai, László Ábel and Starecki, T and Suchenek, M and Surányi, Gergely and Szalai, Sándor and Varga, Dezső and Vasúth, Mátyás Zsolt and Ván, Péter and Vásárhelyi, Balázs and Wesztergom, Viktor and Wéber, Zoltán}, doi = {10.1088/1361-6382/aa69e3}, journal-iso = {CLASSICAL QUANT GRAV}, journal = {CLASSICAL AND QUANTUM GRAVITY}, volume = {34}, unique-id = {3227934}, issn = {0264-9381}, keywords = {portable muon tomograph; long term underground microseismicity; low frequency underground noise; Einstein Telescope; Matra mountain range}, year = {2017}, eissn = {1361-6382}, orcid-numbers = {Dobróka, Mihály/0000-0003-3956-2070; Kovács, Róbert Sándor/0000-0001-5822-6035; Oláh, László/0000-0002-4300-8331; Varga, Dezső/0000-0002-2450-1331; Ván, Péter/0000-0002-9396-4073; Vásárhelyi, Balázs/0000-0002-0568-1031; Wéber, Zoltán/0000-0002-0017-3505} } @article{MTMT:3216614, title = {A Mátrai Gravitációs és Geofizikai Laboratórium első mérései és mérési programja [First report of long-Term measurements of the MGGL Laboratory in the Mátra mountain range]}, url = {https://m2.mtmt.hu/api/publication/3216614}, author = {Barnaföldi, Gergely Gábor and Bulik, T and Cieslar, M and Dávid, Ernő and Dobróka, Mihály and Fenyvesi, Edit and Gondek-Rosinska, D and Gráczer, Zoltán and Hamar, Gergő and Huba, G and Kis, Árpád and Kovács, Róbert Sándor and Lemperger, István and Lévai, Péter and Molnár, József and Nagy, Dávid and Novák, Attila and Oláh, László and Pázmándi, Péter and Piri, D and Starecki, T and Suchenek, M and Surányi, Gergely and Szalai, Sándor and Varga, Dezső and Vasúth, Mátyás Zsolt and Ván, Péter and Vásárhelyi, Balázs and Wesztergom, Viktor and Wéber, Zoltán}, journal-iso = {MAGYAR GEOFIZIKA}, journal = {MAGYAR GEOFIZIKA}, volume = {57}, unique-id = {3216614}, issn = {0025-0120}, year = {2016}, eissn = {2677-1497}, pages = {152-169}, orcid-numbers = {Dobróka, Mihály/0000-0003-3956-2070; Kovács, Róbert Sándor/0000-0001-5822-6035; Oláh, László/0000-0002-4300-8331; Varga, Dezső/0000-0002-2450-1331; Ván, Péter/0000-0002-9396-4073; Vásárhelyi, Balázs/0000-0002-0568-1031; Wéber, Zoltán/0000-0002-0017-3505} } @article{MTMT:3160540, title = {Forward electron emission in collisions of He2+ ions with Ar atoms with simultaneous capture of two electrons}, url = {https://m2.mtmt.hu/api/publication/3160540}, author = {Sarkadi, László and Nagy, Dávid}, doi = {10.1103/PhysRevA.94.042709}, journal-iso = {PHYS REV A}, journal = {PHYSICAL REVIEW A}, volume = {94}, unique-id = {3160540}, issn = {2469-9926}, abstract = {The energy spectrum of the electrons ejected in forward direction from Ar atoms with simultaneous bound-state capture of two electrons has been measured by impact of 30 keV/amu He2+ ions with the aim to clarify the discrepancy between the results of two previous experiments concerning the existence of the cusp-shaped peak for electrons with velocity close to the ion velocity. A peak structure has been observed which is dominated by a broad cusp attributed to the zero-energy electron emission in the projectile-centered reference system at the 2S3 excitation threshold of He0. Further narrower peaks have been identified as results of the decay of autodetachment resonant states of He- populated during the collision by three-electron bound-state capture. © 2016 American Physical Society.}, keywords = {IONS; Electrons; Argon; Electron emission; Reference systems; ENERGY SPECTRA; resonant state; Simultaneous captures; Peak structure; Excitation threshold; Electron bound state; Autodetachment}, year = {2016}, eissn = {2469-9934} }
