Dr Martin Precek (ELI ERIC)5/14/26, 1:30 PMRadiation ChemistryInvited
The Extreme Light Infrastructure ERIC (ELI ERIC) is a recently established international research infrastructure providing access to advanced sources of ultrashort pulse laser light and secondary radiation. The infrastructure currently operates three user facilities located in Czechia (ELI Beamlines), Hungary (ELI ALPS), and Romania (ELI NP), offering state of the art experimental stations in...

Hydroxyl radicals ($\mathrm{^\cdot}$OH) are among the key reactive species formed in the course of water radiolysis and they play an important role in subsequent radiation-induced chemical processes in aqueous environment. Quantitative data on $\mathrm{^\cdot}$OH formation under low-energy X-ray irradiation, however, remain limited. In this work, hydroxyl radical formation in aqueous systems...

Rare-earth-based fluoride nanocomposite materials represent a promising platform for applications in radiation-based cancer therapies, particularly in the context of X-ray induced photodynamic therapy (XPDT) [1,2]. Due to their scintillation properties, these materials are capable of converting the ionizing radiation into UV/visible photons, enabling in situ activation of photosensitizers...

Closing the fuel cycle to promote a safe and sustainable nuclear energy requires capabilities to reprocess and multi-recycle U but also major (Pu) and minor actinides (MA: Am, Cm, Np) into new fuels for advanced reactors. Nowadays, the hydrometallurgical processes are the most mature technology able to address actinides recycling within this context, although they are not exempt of important...

Advanced partitioning strategies are essential to enable sustainable closed nuclear fuel cycles and reduce the long-term radiotoxicity of spent nuclear fuel. Among these strategies, the AmSel process targets the separation of americium and curium. This represents a key step for advanced management strategies, as curium exhibits high neutron emission and decay heat, imposing stringent safety...

The purpose of this study is to assess structural changes in three clays following exposure to high gamma radiation. Clays' distinct physicochemical properties—particularly their sorption capacities—make them useful in a wide range of industries and basic research. It is essential to investigate the interactions between radiation and these materials to think about their potential applications...

Fe(CO)5 is a promising precursor-candidate for ice lithography and a typical precursor for Focused Electron Beam Induced Deposition (FEBID) and Focused Ion Beam Induced Deposition (FIBID) processes. Therefore, its radiolysis has been studied in a plethora of model systems but its solid-phase radiation chemistry has not yet been described in depth.
In the case of isolated molecules,...

All-inorganic cesium lead halide perovskite nanocrystals, notably CsPbBr3, are emerging as highly promising candidates for ionizing radiation detection. Their high atomic number, defect tolerance, and ultrafast decay make them ideal for deployment as nanoscintillators, particularly when embedded in scalable polymer matrices. However, their long-term stability under high-energy ionizing...

Hexachlorobenzene (HCB) is a chlorinated aromatic compound classified among POPs due to its high chemical stability and resistance to natural degradation. Because of its persistence and potential environmental toxicity, the development of efficient methods for the destruction of HCB remains an important research objective. Ionizing radiation represents a promising approach for the degradation...

Analog crystal dosimeters have been commonly used for detection of γ radiation for the last 50 years. However, these dosimeters are prone to degradation, show false positive responses and their external evaluation is expensive and unsuitable for sensitive information. Therefore, there is a need to develop an appropriate replacement. A new composite material suitable for colorimetric detection...

Ion exchange resins (IERs) are used extensively in nuclear reactors to maintain low levels of ions in the coolant and moderator loops. In this specific context, IERs from the purification system of the moderator of CANDU-type reactors are investigated. Upon service in the moderator loop, the IERs will eventually become contaminated with radionuclides and will need to be kept in safe storage...

Rare-earth doped cerium-lanthanum fluoride nanoparticles have shown great potential for cathodoluminescent (CL) imaging [1] and possible application in X-ray photodynamic therapy [2]. Besides chemical stability or suitable size it is also essential to find optimal luminescent properties of these materials via tuning of cerium [1] and terbium content. This work focuses on composition-based...

Spent ion-exchange resins (SIERs) constitute one of the most volumetrically significant fractions of low- and intermediate-level radioactive waste generated in the nuclear industry. According to IAEA estimates, annual generation from operating nuclear power plants amounts to 3000–5000 $m^3$. Beyond their large volumes, these wastes are challenging due to their high organic content, which...
