1. Effective microorganisms technology applied to sewage sludge and tested in short exposure on Lepidium sativumTanja Buh, Leja Goljat, Darian Rampih, Petra Makorič, Sara Pignattelli, 2024, izvirni znanstveni članek Opis: Sewage sludge has fertilizer properties and can supply a large amount of necessary nutrients to the crops, because it is full of
organic matter, carbon, nitrogen and other nutrients, but on the other hand, it also contains a lot of toxic compounds, derived
from its origin, such as heavy metals, antibiotics and microplastics. Effective microorganisms are a collection of naturally
occurring beneficial microorganisms that are able to coexist and are commonly used in agriculture and gardening to improve
plant performance and production. In this study, increasing concentrations of sewage sludge alone and added with effective
microorganisms were evaluated in a short exposure on Lepidium sativum L. Parameters that were evaluated are: (i) percentage
inhibition of germination, (ii) root length, (iii) biomass, (iv) soil pH, (v) total organic carbon and nitrogen both at soil and
at root level. Results carried out from our experiment highlighted that effective microorganisms when coupled with sludge
are able to restore biometric parameters by resetting seeds germinability inhibition and improving root elongation more than
50% when compared with plants added only with sludge, restoring the values almost of those to the control plants, as well
as for soil pH values. Total organic carbon and total nitrogen are boosted at soil level almost at 50% when compared with
the same concentrations added only with sludge, while at root level they appear decreased only in plants directly added with
sludge treated with effective microorganisms

8. Ferrite-based magnets by high pressure consolidationCesár De Julián Fernández, Blaž Belec, Aleksander Učakar, Petra Jenuš, 2023, objavljeni povzetek znanstvenega prispevka na konferenci Opis: M-type hexaferrite magnets constitute together the rare-earth magnets the most employed magnets in the
world. Even if ferrite magnets have smaller energy product and lower magnetization saturation than rare-earth
permanent magnets (PMs), currently ferrite magnets represent the most widely used PMs, covering 80% of the
PM market production [1,2]. Recently, a strong effort is being performed to improve the magnetic properties
of ferrites with the scope of substituting partially rare-earth magnets. Most of the strategies involve the
nanostructuration of the ferrites and/or the development of hybrid compounds [3]. A bottleneck for the
production of these magnets is that standard sintering process requires high temperatures and oxidizing
atmosphere that produces the destruction of the nanostructure and several chemical changes. Different novel
strategies as out-of-equilibrium or cold sintering processes are mainly considered[2,4].
In our presentation we will show the production of dense ferrite-based magnets by high pressure multi-Anvil
press at low temperatures. This press applies quasi-isotropic pressures in the range up to 20 GPa and
temperatures up to 1200°C. We demonstrate that the consolidation of micrometric hexaferrite (SrFe12O19)
powders is possible at temperatures below 1000°C, below the standard sintering temperatures. In addition,
dense hybrid magnets were obtained composed of micrometric hexaferrites and soft high magnetization metal
Fe or FeCo NPs applying pressures up to 6 GPa and low temperatures (250°C). A deep study, including
structural, morphological and magnetic characterizations, has been performed to determine the influence of the
temperature and pressure consolidation conditions in the properties of these novel magnets. Magnetic
characterizations show that hybrid magnets exhibit larger magnetization than ferrites and single step hysteresis
loops. Single Point Detection characterizations indicate that the anisotropy field of the hybrid magnets is similar
to that of the ferrite magnets. These results suggest that the two moieties componing the high pressure
consolidated magnets have similar properties than the original micro and nano powders, but they are magnetic
coupled during the reversal process. High pressure consolidation appears as a promising technique to obtain
nano-based metal-oxide hybrid magnets with promising hard properties.
