AB  - Light-transmitting measurements of white light and a consequentially chosen laser beam of 655 nm propagating through citrate- and oleate-coated CoFe 2 O 4 , FeFe 2 O 4 and MgFe 2 O 4 nanoparticles under the influence of an external magnetic field were presented. New experimental settings were developed for the optical study of ferrites’ behavior in ferrofluid with the applied magnetic field strength within the 30–400 mT range. A magnetic field-induced change of light transmittance occurred and a precipitation of all studied samples was obtained. Optical investigations of ferrofluid suspensions revealed that, contrary to the linear aggregates of colloidal CoFe 2 O 4 and FeFe 2 O 4 , spheroidal aggregates were formed in the case of MgFe 2 O 4 . In all three cases, the surface modification resulted in decreased dipole–dipole interactions between ferrite cores, and thus, less precipitates were noticed. All oleate-coated nanoparticles have demonstrated weaker magnetic responses compared to the citrate-encapsulated samples. The aggregation of nanoparticles potentially increases cytotoxicity. Regarding non-linear clustering of MgFe 2 O 4 suspensions, it can be concluded that its excretion from the organism may likely be easier and faster when used in diagnosis and/or therapy. Therefore, more attention should be paid to the lowly toxic MgFe 2 O 4 regarding its medical application. © 2019

AB  - Using simple optical measurements, the selective spectral behavior of suspended nano-particles of magnetite (Fe3O4) and cobalt-ferrite (CoFe2O4) coated with starch, was observed through switching on/off of external magnetic field. The field strength was varied in the interval 30–300 mT. In these transient regimes, the unexpected and unusually large changes of transmitted light occur. An explanation is suggested, within the model based on ordering of magnetic moments of nano-particles along the lines of magnetic field into magnetic chains and organization of magnetic chains into spatial structure—a quasi-lattice. This fact indicates the possibility of more efficient local heating of nano-particles in the fast changing magnetic field; for instance when taking magnetic nano-particles for therapeutic purposes.

AB  - Galvanization process requires the use a large amount of water and produces wastewaters that are usually purified by conventional cost-effective procedure. This kind of treatment generates waste sludge which becomes a hazardous if is not properly stabilized. Hence, the aim of this paper is to investigate the characteristics of galvanic sludge through the inspection of its physicochemical parameters and consider stabilization of waste materials, including waste glass and aluminum slag by their conversion into an eco-designed material referred to as glass ceramics. The obtained products have been studied by X-ray diffraction (XRD). XRD analyses confirmed occurrence of chemical and phase transformations in treated galvanic sludge and binding of toxic metals (Al3+, Cr3+, Cu2+, Cd2+, Ni2+, Pb2+, Zn2+) into crystalline phases and very sTab. structure.
AB  - Процес галванизације захтева велику количину технолошке воде што има за последицу стварање отпадних вода, које се из економских разлога пречишћавају конвенционалним системима. Овим третманом настаје отпадни муљ који, уколико се адекватно не стабилизује, представља опасан отпад. У том смислу, у раду је извршена карактеризација галванског муља анализом физичкохемијских параметара компонената, а затим стабилизација ових отпадних материја, укључујући отпадно стакло и алуминијумску шљаку, превођењем у еко-синтеровани материјал стаклокерамика. Добијени производ анализиран је рендгенском дифракционом анализом (XRD). На основу XRD спектра потврђене су хемијско-фазне трансформације третираног галванског муља и везивање токсичних метала (Al3+, Cr3+, Cu2+, Cd2+, Ni2+, Pb2+, Zn2+) у веома стабилну кристалну структуру.
