AB  - Praćenje pojave i brzine korozije, nastanak termičkih oksida na površini metalnih delova eletroenergetskog postrojenјa, kao i način njihovog otklanjanja na način koji je tehnološki pogodan, ekonomski pristupačan i ekološki opravdan prikazan je u ovom tehničkom rešenju Ispitivanjem je ustanovljeno da su metalni delovi na kojima se javlja korozija izrađeni od na nerđajućeg čelika AISI 304, pa je pojava korozije i termičkih oksida praćena je u odnosu na to, kao i sastav prašine sa kojom su metalni delovi u kontaktu. Pojava termičkih oksida na površini nerđajućih čelika posledica je povišene temperature na mestu zavarivanja metalnih delova.
Merena je vrednost pH oba rastvora: etalonskog i zasićenog rastvoru prašine iz pogona.
Sastav uzoraka prašine određen je FTIR metodom, pa su na osnovu prisutnih jona u rastvoru definisana ostala ispitivanja.
Određivan je korozioni potencijal Ekor, vrednost otpora polarizacije Rp, kao i gustina struje korozije jkor. Sva ispitivanja nerđajućeg čelika u etalonskom rastvoru i u zasićenom rastvoru prašine iz pogona firme naručioca, rađena su za 1 sat i u toku 25 dana.
Kao rezultat svih istražoivanja, date su tehnološke preporuke i način otklanjanja korozije i termičkih oksida.
Rešenje je prodato naručuicu u toku 2020.godine, a od januara 2021.godine primenjeno u postrojenju naručioca, ELNOS BL d.o.o., koji su izjavom potvrdili primenu ovog tehničkog rešenja u svom poslovanju.
AB  - Monitoring the occurrence and rate of corrosion, the formation of thermal oxides on the surface of metal parts of the power plant, as well as the method of their elimination in a way that is technologically suitable, economically affordable and environmentally justified is shown in this technical solution. It has been established that the metal elements affected by corrosion were made from stainless steel AISI 304. Accordingly, the occurrence of corrosion and thermal oxides was monitored based on the material and the composition of the dust with which the metal parts are in contact. The emergence of thermal oxides on the surface of stainless steels is a consequence of the elevated temperature at the welding site.
The pH value of both solutions was measured: standard and saturated solution of dust from the plant. The composition of the dust samples was determined by FTIR. The other tests were defined based on the ions present in the solution.
The corrosion potential, the value of the polarization resistance, as well as the corrosion current density were determined. All tests of stainless steel in the standard solution and in the saturated solution of dust were performed for one hour within a span of 25 days.
Technological recommendations on how to eliminate corrosion and thermal oxides are provided.
The solution has been applied since January 2021 by ELNOS BL d.o.o.

AB  - The cytotoxicity of amorphous calcium phosphate (ACP) and chitosan lactate (ChOL) multifunctional and hybrid composite coatings on MRC-5 human lung fibroblast cell line was elucidated. ACP/TiO2 and ACP/TiO2/ /ChOL were deposited onto Ti by a novel in situ anodization/anaphoretic process at constant voltage. Cytotoxicity tests showed that there was no significant decrease in the survival of healthy MRC-5 cells exposed to composite samples without chitosan lactate, while there was an increase in the number of viable cells in the sample containing ChOL. These findings show that there was improved cell proliferation, differentiation and cell viability in the ChOL-containing sample, which makes ACP/TiO2/ChOL coating a good candidate for applications in medicine and stomatology.

AB  - Usled razvoja industrije i rastom populacije tokom poslednjih godina javljaju se problemi u vezi sa otpadnim vodama iz proizvodnje koje je neophodno rešavati na ekološki i ekonomičan način. Sve otpadne vode iz postrojenja bez obzira kako su nastale sadrže štetne materije koje mogu da imaju i određen stepen toksičnih primesa, moraju se prečistiti ako njihov kvalitet ne odgovara zakonskim okvirima. Svrha tretmana otpadnih voda je uklanjanje štetnih materija čime se postiže smanjenje stepena njene zagađenosti, a istovremeno se ostvaruje i određen ekonomski i ekološki efekat. Ovo tehničko rešenje predstavlja optimizaciju procesa prečišćavanje otpadnih voda Fabrike streljačke municije u Uzićima. Otpadna voda je prečišćavana postupkom taloženja uz upotrebu kalcijum-oksida u cilju uklanjanja koloidnih materija i teških metala. Većina zagađujućih materija su organskog porekla i njihovo ukljanjanje vršeno je primenom naprednih oksidacionih procesa korišćenjem ozona i ozona u kombinaciji sa ultrazvukom u cilju postizanja kvaliteta vode koji odgovara zakonskoj regulativi. Unapređeni procesi oksidacije predstavljaju najefikasnije metode za uklanjanje i degradaciju teško rastvornih zagađujućih materija iz otpadnih voda. Proces prečišćavanja je optimizovan u odnosu na tehnološki postupak, koncentraciju, vreme tretmana i količinu primenjenog oksidacionog sredstva. Stepen zagađenosti vode organskim jedinjenjima je određivati na osnovu merenja HPK, BPK i koncentracije teških metala (olovo, gvožđe, hrom, bakar, cink, aluminijum).
AB  - Due to the development of industry and population growth in recent years, there are problems related to industrial wastewater that needs to be addressed in an environmentally friendly and economical way. All wastewater from plants, regardless of how it was generated, contains harmful substances that may have a certain degree of toxic impurities and must be treated if its quality does not meet the legal requirements. The purpose of wastewater treatment is the removal of harmful substances, which reduces the degree of its pollution, and at the same time achieves a certain economic and environmental effect. This technical solution ensures the optimization of the wastewater treatment process of the Ammunition Factory in Uzići. Wastewater is purified by a precipitation process using calcium oxide to remove colloidal substances and heavy metals. Most of the pollutants are of organic origin and their removal is performed by applying advanced oxidation processes using ozone and ozone in combination with ultrasound in order to achieve water quality that complies with legal regulations. Advanced oxidation processes are the most efficient methods for removing and degrading poorly soluble pollutants from wastewater. The purification process is optimized in terms of the technological process, concentration, treatment time and the amount of oxidizing agent applied. The degree of water pollution with organic compounds is determined on the basis of measurements of HPK, BOD and the concentration of heavy metals (lead, iron, chromium, copper, zinc, aluminum).
