Heavy mineral separates from Hungarian sand samples were measured by instrumental NAA at the Budapest Research Reactor (BRR), but the amounts and weights of them were way too small to also analyze them effectively at the PGAA station of the BNC. Combined PGAA and in-beam NAA experiments were made on the samples at FRM-II to study their possibilities.
First, the mineral separates were...
Laser powder bed fusion (PBF-LB/M) of metallic alloys is a layer wise additive manufacturing process which provides significant scope for more efficient designs of components, benefiting performance and weight, leading to efficiency improvements for various sectors of industry. However, to benefit from these design freedoms, knowledge of the high produced induced residual stress and mechanical...
Electrochemistry – especially within the context of energy storage, has become a key element of society. Understanding its processes is essential, e.g., for the making of cheaper, lighter and safer batteries or the synthesis of novel functional materials. A number of the concerned processes takes place at so-called “buried-interphases”, which can only be investigated using advanced...
Slot-die coating is a versatile and roll-to-roll compatible deposition technique that aims to lower production costs for thin-film-based perovskite solar cells. Our custom-built slot-die coater offers advanced morphology control capabilities and is compatible with in situ GISAXS/GIWAXS (grazing-incidence small/wide-angle X-ray scattering) and photoluminescence measurements [1]. Morphology...
Among new alloy systems being developed to supplement Ni-based superalloys in gas turbine applications, the Co-Re-based alloys show promise because of their excellent specific strength and relatively high melting range (1490°-1560°C). Alloying elements with various functions are added to these alloys. For example, Cr, and Ni, for oxidation resistance. Since the Co matrix undergoes an...
Imaging techniques based on neutron beams are rapidly developing and have become versatile non-destructive analysing tools in many research fields. Due to their intrinsic properties, neutrons differ strongly from electrons, protons or X-rays in terms of their interaction with matter: they penetrate deeply into most common metallic materials while they have a high sensitivity to light elements...
The neutron strain pilot projects within H2020- Sine2020 and BRIGHTNESS2 towards European neutron landscape & users have been key for facilitating industry access and collaborations in a regular basis. The shortcomings reducing the industrial experimental throughput are well known and very similar to all facilities. A central issue is the non-acceptance by industry to use the neutron technique...
The establishment of the spectroscopy data library for prompt gamma activation analysis (PGAA) was initiated 25 years ago, as no reliable (n,gamma) database existed for analytical purposes. The database lists partial cross sections and peak energies of elements used in chemical analysis. The first versions were published in [1], also in IAEA TECDOC, and has been used worldwide. More than...
Inspired by the possible storage of nuclear waste in impermeable rock salt formations, numerous theoretical and applied studies have investigated the effect of gamma irradiation on the structural properties of halite over the last five decades. An important discovery has been the gamma irradiation - induced decoration of othervise invisible lattice defect substructures in this optically...
