AB  - The discovery of nanostructured materials led to ground-breaking findings and significant technological advancement in recent years and is therefore attracting continuous attention from both, academia, and industry for a variety of structural and functional applications [1]. To design nanostructured materials with new functionalities, we combine electrochemical and electroless chemical synthesis with structural studies on different length scales including transmission electron microscopy. The possibility to produce nanostructured metals containing nanoscaled twins, both growth twins and deformation twins, is considered as a promising approach for the synthesis of novel high-performance materials in recent years [1]. Unfortunately, the phenomenon of twinning occurs only in certain metals, such as copper and until recently, it seemed impossible to make aluminium with a high density of grown-in twins. In the present work, we demonstrate the use of electrodeposition as synthesis method to make Al layers with a high density of genuine growth twins [2]. This unexpected result demonstrates a versatile and cost-effective nanoengineering technique for the formation of pure Al layers with a high density of twins. The atomic structure of a twin in aluminium is shown in a transmission electron microscopy image (cf. Fig. 1). In high density, these symmetric lattice imperfections can yield a material that shows good electrical properties, high hardness and good deformability. In addition, we show that electrochemical synthesis approaches can be used to create high surface area functionalized foams and ordered nanostructures for potential sensing and energy-related applications [3-6].

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).

AB  - It is the aim of our work to carry out fundamental studies on designing and synthesizing high surface area functionalized foam and ordered structures for their potential sensing and energy related applications. We combine electrochemical synthesis with structural studies on different length scales including transmission electron microscopy. Templates are directly grown by electrodeposition, either by hydrogen bubble formation or by utilizing of ordered structures formed by anodic electrochemical oxidation. [1-3] We employed an elegant approach to obtain open, foam deposits of Ni and Ni alloys, by using electrodeposition at high current densities, to promote hydrogen evolution and bubble templating (cf. Fig.1). [1] In the next step, the high surface area of such materials was funtionalized by Pd utilizing galvanic displacement reaction. Electrochemical testing of the obtained open foam deposits shows promissing catalytical activity for hydrogen evolution in alkaline environments, as well as methanol and ethanol oxidation. In the case of fabrication of nanodendritic Ag simultaneously grown with porous anodic aluminium oxide we accomplished well anchored dendritic Ag nanostructures [2] of long-term stability [3].
