AB  - In this study, different forms of copper films were
electrodeposited (ED) on silicon wafer, copper and brass foils.
The effect of monocrystalline Si(111) surface cleaning method
and electrodeposition conditions and regimes (frequency in the
pulsating current (PC) regime, an addition of additives in
electrolyte for the constant galvanostatic (DC) regime, and
thickness) on surface morphology and wettability of copper films
was investigated. Optical microscopy equipped with highresolution camera, scanning electron microscopy (SEM) and an
atomic force microscopy (AFM) were used for thin film
characterization and to evaluate wettability of copper films. The
sessile drop method was used for the measurement of water
contact angle. According to the obtained results, choice of
electrolyte used in ED greatly affects wettability of copper films.
It was also shown that copper films electrodeposited from basic
sulfate electrolyte with varying current regimes frequencies,
thicknesses, and cathode types have opposite trends between
roughness parameter values and the water contact angle value.
Structural-morphological changes of a film or bulk solid surface
are key parameters in determining wettability properties and the
analysis of the wetting angle oscillations, but not the only one.

AB  - Biocomposite materials are a combination of two or more different biomaterials at the
macroscopic level, with competitive mechanical and insulation properties, relatively stable when
exposed to high temperatures and tailorable. In this paper, materials are with a vegetative part of
fungi (mycelium-mesh structure of hyphae) which are increasingly used to create biocomposites
with unique processing technology. The vegetative part of a fungus called mycelium, can serve as
a natural binder for products made of biocomposite and acts like a self-assembling adhesive by
digesting and adhering to the surface of specific organic matter. This paper presents the
development of mould technology to set the biocomposite structure and test its mechanical
characteristics. The primary purpose of the mould is to bring the loose natural material into a
solid preparation following the standards ASTM D7250 and ASTM D1037, which include testing
the technologically prepared and hardened sample for tensile and pressure. Development and
moulding of biocomposite are the technological processes of drying after sowing mycelium so a
variant of the mould with a perforated upper part was used to harden the samples thoroughly.

AB  - The 6R strategy plays an essential role in the sustainable development of the aviation industry, which is reflected in the application of new materials and new technologies. Additive technologies enabled rapid prototyping production and modified components as a quick response to market turbulence. The aim is to show the primacy of additive technologies concerning conventional manufacturing methods. This paper will define the reverse engineering (RE) implementation algorithm in the 6R strategy. The emphasis here is on using non-metallic materials: polymers, composites and other materials. Mentioned materials are gaining an increasing role in those places where the geometry of parts is complex. By definition, the 6R strategy includes reduction of waste material (Reduction); reuse of waste material (Reuse); waste collection (Recycling); regeneration of raw materials and energy from waste material (Recovery), redesign of a product or a complete business process (Redesign) and reproduction that includes disassembly, cleaning, measurement and testing of parts (Remanufacturing). Applying RE makes it possible to design a new spare part based on the existing fundamental machine part. The RE procedure is realized from creating a digital 3D model, through the permanent improvement and optimization of model parameters, to the production of the finished part using additive technologies.

AB  - Sve veća upotreba aditivnih tehnologija zahteva potpunu implementaciju 7S alata. Osnovna suština je da se viškovi i otpad u preduzeću eliminišu što je više moguće kroz poznate Lean tehnike. Međutim, primena 7S alata uključuje još dva bitna elementa: bezbednost i timski rad. U savremenim proizvodnim procesima preduzeća moraju da obrate pažnju na ulogu zaposlenih u obezbeđivanju organizacione kulture i potpune bezbednosti na radu. Da bi se obezbedila konkurentska pozicija na tržištu, neophodno je ispitati povezanost svih elemenata alata 7S sa principima aditivne proizvodnje. Aditivna proizvodnja polako zamenjuje konvencionalnu proizvodnju. Međutim, u oba slučaja mora se voditi računa o zaštiti zdravlja zaposlenih na radnom mestu. Isparenja tokom proizvodnog procesa i opasne čestice praha čine aditivnu proizvodnju nestabilnijom. Ovim radom smo pokušali da pokažemo koliko su Lean alati vitalni u funkcionisanju aditivne proizvodnje.
AB  - The increasing use of additive technologies requires the complete implementation of 7S tools. 
The fundamental essence is to eliminate surpluses and waste in the enterprise as much as
possible through the known Lean techniques. However, the application of the 7S tool incorporates two more essential elements: safety and teamwork. In modern production processes, enterprises must pay attention to the role of employees in ensuring the organizational culture and complete safety at work. In order to ensure a competitive position in the market, it is indispensable to examine the connections of all elements of the 7S tool with the principles of additive manufacturing. Additive manufacturing is slowly replacing conventional manufacturing. However, in both cases, care must be taken to protect employees' health at the workplace. Fumes during the production process and dangerous powder particles make additive manufacturing more unstabile. With this work, we tried to show how vital Lean tools are in the functioning of additive manufacturing.

AB  - The rising cost of fossil fuels has prompted a shift towards environmentally friendly alternative energy sources, leading to an expansion in the study of renewables. Wind turbines, specially those of the small-scale variety, have emerged as a promising solution for generating sustainable electricity, particularly in rural areas and for smaller consumers. This study focuses on the analysis of pitch angles for three-bladed horizontal axis wind turbines (HAWT) with a diameter of 1.35 m, classified as micro wind turbines. The analysis assumes incompressible and viscous flow, with shear stress transport (SST) equations closed by various turbulence models. The ANSYS program was used for conducting this analysis.

AB  - The utilization of biomaterials with mycelia as a stabilizing agent is gaining popularity in the fields of construction and architecture, offering a sustainable solution aligned with the principles of the circular economy. Interdisciplinary research involving biologists, technologists, and engineers is necessary to advance this field where science, art and design converge. These biomaterials contribute to energy reduction and cost-effectiveness, utilizing readily available and recyclable raw materials. Mycelium-based blocks have shown to be more affordable than traditional cement and gypsum blocks while significantly reducing CO2 emissions. The mycelium network, formed by hyphae, can be cultivated into a solid material, providing a defined technological process. This study focusses on performing 3-point bending testing on moulded specimens using additive technology PLA material, following the ASTM D1037 standard. After the growth of mycelium and the formation of the test tube-shaped structure, the samples are dried and characterized to enchance their mechanical characteristics.

AB  - The manufacturing and application of biocomposites are remarkable achievements in replacing conventional non-biodegradable materials. In general, biocomposites are made up of biopolymers and bio-based reinforcing agents. Biofibres are also the main constituents of biocomposites, which are generated from biological entities such as crop fibres (cotton, flax, mycelium of fungi, hemp), recycled wood, wastepaper, agro-based by-products or regenerated cellulose fibre. In this paper, a mould intended for biocomposites based on mycelium and an adequate substrate is tested. The primary purpose of the mould is to bring the loose natural material into a solid preparation following the standards ASTM D7250 and ASTM D1037, which include testing the technologically prepared and hardened sample for tensile and pressure. Development and moulding of biocomposite are the technological processes of drying after sowing mycelium so that a variant of the mould with a perforated upper part was used to harden the samples thoroughly. In the mould, realization is used PLA thermoplastic filaments. Mould was made as an assembly of two parts, and its shape is like a dog bone, according to the mentioned standards. This polymer enclosure is helpful for other biocomposite structures (a mixture of different fungi species and adequate substrates).
AB  - Proizvodnja i primena biokompozita je značajno doprinela smanjenju upotrebe nebiorazgradivih materijala. U opštem smislu, biokompoziti se sastoje od biorazgradivih prirodnih polimera (biopolimera) i ojačavajuće faze-biovlakana. Biovlakna su glavni sastojci ovih materijala i mogu biti različitog prirodnog porekla (pamuk, lan, konoplja, micelije gljiva, reciklirano drvo, agroproizvodi ili regenerisana celulozna vlakna). U ovom radu, testiran je i razvijen kalup za biokompozite na bazi micelijuma i odgovarajućeg supstrata (pšenične slame). Osnovna namena kalupa je priprema i očvršćavanje bio materijala da bi bilo omugućeno ispitivanje u skladu sa standardima ASTM D7250 i ASTM D1037, koji su namenjeni ispitivanju uzoraka na istezanje i pritisak. Izrada i 
oblikovanje biokompozita predstavljaju tehnološke postupke koji se sprovode u cilju sušenja i smanjenja procenta vlage nakon zasejavanja, pri čemu je gornji deo perforiran zbog isparavanja i što boljeg očvršćavanja uzoraka. Za proizvodnju kalupa upotrebljen je PLA termoplastični filament. 
Kalup je izrađen kao dvodelni sklop, oblika “dog bone” u skladu sa pomenutim standardima.

AB  - This paper presents the static testing of the composite material's mechanical  characteristics. An overview of the standards is made by which various tests are performed, and then  an analysis of the results of the parameters obtained by the conventional method-stretching and optical  (DIC system-bending) of carbon epoxy composite structures is given. These results represented the  basis for the preparation and further application of biocomposite materials; that is, the testing  procedure will be performed identically on composites containing mycelia. The mould for pressing  biomaterial connected with mycelium is made of two parts. The primary purpose of the mould is to  bring the loose natural material into a solid preparation following the standards ASTM D3039 and  ASTM D7078, which include testing the technologically prepared and hardened sample for bending  and shearing.

today. New combinations of materials and new structures that change
fashion trends are obtained. The paper presents the technology of joining thermoplastic
materials with different fabrics. For example, the realization of a button on
textiles and the description of 3D printing were taken. This pioneering venture describes
the technology, fabric model-making process, and materials melting bond
analysis. Unfortunately, available thermoplastic materials have many limitations
regarding durability, aging, and service life according to the defined requirements.
The idea of this paper is the application of 3D printing in the fashion industry as
an emerging topic for discussion. The experimental part of this investigation will
provide a new guideline for designers of PLA/ABS printing elements on textile
substrates and possibility for application in modern textile design.

AB  - In this paper, a comparison of conventional and additive manufacturing was made. Lean and sustainable manufacturing from the point of view of waste were also analyzed. It was established that conventional manufacturing is slowly being replaced by additive manufacturing, but its role is still significant. Lean manufacturing indicates that waste is everywhere, i.e. at all organizational levels. Sustainable manufacturing analyzes new technologies and measures their impact on environmental protection with as little resource consumption as possible. The paper examined the importance of additive manufacturing in sustainable manufacturing by considering Lean principles. In conclusion, there is a flowchart of documents and activities that methodologically introduce additive manufacturing through respect for Lean principles and sustainable production. Savings in production time, launching new products, and quick replacement of parts have become imperative today, and further continuation of this work should be aimed at defining models and procedures in the company's sustainable development.

At the beginning, during the pioneer period, flying was completely in the hands of the pilot and he made all the decisions based on his experience and psychophysical abilities. With the complexity of aircraft and flying, technological, ergonomic and safety conditions have an increasing influence on piloting technique. This paper describes the technological conditions and the development of instrumentation and flight automation systems. The application of the digital cockpit establishes many positive standards, but also raises questions about the further direction of aviation development. A special review describes the use and development of one of the basic instruments in the cockpit -the compass.

AB  - Composite materials and structures are widely used and applied in many
industries owing to their advantages, such as satisfactory stiffness-to-mass ratio
and corrosion resistance. However, during their operating life, responsible parts
subject to complex loads may change and their properties might deteriorate. To
ensure structural integrity it is necessary to monitor and regularly check the
performance of composite structures. This paper investigates the change of
frequency characteristics of two rectangular composite (carbon-epoxy) plates after
inflicting structural damage. Following the necessary preparation of the structure's
upper surfaces by white-and-black stochastic pattern, the responses (free
vibratory movement) of structures to momentary excitation were recorded by an
optical, contactless 3D digital image correlation (DIC) system that contains a set of
ultrafast cameras. In order to determine the natural frequencies of the plates, the
recorded time-domain responses were post-processed, i.e. converted to the
frequency domain by fast Fourier transform (FFT). The reduction in values of
natural frequencies is observed on the damaged structures. The performed
experiments demonstrate the applicability of the DIC method in the structural
health monitoring of composite parts.

AB  - Three different and very small amounts of alumina (0.2, 0.3 and 0.5 wt. %) in two sizes
(approx. 25 and 100 nm) were used to enhance the wear characteristics of ZA-27 alloy-based nanocomposites.
Production was realised through mechanical alloying in pre-processing and compocasting
processes. Wear tests were under lubricated sliding conditions on a block-on-disc tribometer, at two
sliding speeds (0.25 and 1 m/s), two normal loads (40 and 100 N) and a sliding distance of 1000 m.
Experimental results were analysed by applying the response surface methodology (RSM) and a
suitable mathematical model for the wear rate of tested nanocomposites was developed. Appropriate
wear maps were constructed and the wear mechanism is discussed in this paper. The accuracy of the
prediction was evaluated with the use of an artificial neural network (ANN). The architecture of the
used ANN was 4-5-1 and the obtained overall regression coefficient was 0.98729. The comparison of
the predicting methods showed that ANN is more efficient in predicting wear.

AB  - This paper investigates the implementation of additive manufacturing
(AM) in circular production (CP) through the 6R strategy. The methodology
allows designers to reconsider their decisions, correct mistakes or make specific
changes to the model in all phases of the design process, from initial drawings to
the finished product. CP enables the complete realisation of the model/prototype
with a particular focus on environmental protection and the additional use of
recycled waste. The proposed algorithm is tested through the design and manufacturing
of an enclosure of an industrial temperature transmitter. Some of the
weaknesses of additive manufacturing, such as mechanically damaged surfaces,
surface roughness, and tearing of models on weak joints, have been investigated,
and recommendations for mitigation are given.
The mechanical product finishing methods are described in detail in the paper
as well, and in order to check the prototype functionality, some tensile, thermal
stress and drop tests were performed, and the results were analysed and discussed.
It was shown that significant savings in time, cost and material can be achieved by
implementing AM in realising a fully functional prototype while simultaneously
in line with the demands for CP and 6R.

AB  - Microreactors are microfluidic devices with a network of channels where chemical reactions can take place. The diameter of those channels is less than 1 millimeter. Advances of such devices are reduction of the time required for the synthesis, better control of the reaction and the size of nanoparticles. There are different materials from which microreactors can be fabricated. The most common are silicon (Si), polymers, glass, ceramics and metals. In this study, we used Si/Pyrex glass and poly(dimethylsiloxane) (PDMS) materials to fabricate two types of microreactors. Both types of microreactors had integrated heaters but different length and width of microchannels. Reaction was performed on the same temperature (80⁰C) and with the same reaction time in both microreactors. Synthesis of titanium (IV)-oxide nanoparticles was performed in these microreactors, in order to show how dimension of microchannels can affect the size of nanoparticles. Size distribution of nanoparticles was determined with dynamic light scattering (DLS). It was concluded that dimensions of microchannels had great influence on the size of the nanoparticles.

AB  - Composite systems of electrodeposited 10 µm Cu coatings on Cu foils and 30 µm Cu coatings on brass foils were obtained in direct current regimes (DC) from electrolytes without/with additives. Different regimes of stirring electrolytes were investigated: stationary, magnetic, and ultrasonic. Also, multilayered Cu coating was successfully obtained by the electrodeposition with periodic ultrasonic/magnetic stirring of basic sulfate electrolyte. A bending test technique was used to assess the adhesive strength to the cathodes. Vickers indentation test machine was used for measuring composite hardness in the micro-range. The adhesion parameters named “the critical reduced depth” and “critical cycle number” for the Cu coatings proved suitable for assessing the adhesion behavior. Composite hardness models of Korsunsky and Chen-Gao were applied in order to calculate an intrinsic hardness of the coatings and for an assessment of adhesion performance. The corrosion resistance of the Cu coatings was investigated using the “static corrosion test.” A comparative study showed that the Cu coatings produced in ultrasonic agitation regime or in laminate form have better mechanical properties and better corrosion resistance. It has also been shown that Cu coatings synthesized from electrolyte with additives are structurally superior, but a “soft hardening effect” was observed.

abstract = "Composite systems of electrodeposited 10 µm Cu coatings on Cu foils and 30 µm Cu coatings on brass foils were obtained in direct current regimes (DC) from electrolytes without/with additives. Different regimes of stirring electrolytes were investigated: stationary, magnetic, and ultrasonic. Also, multilayered Cu coating was successfully obtained by the electrodeposition with periodic ultrasonic/magnetic stirring of basic sulfate electrolyte. A bending test technique was used to assess the adhesive strength to the cathodes. Vickers indentation test machine was used for measuring composite hardness in the micro-range. The adhesion parameters named “the critical reduced depth” and “critical cycle number” for the Cu coatings proved suitable for assessing the adhesion behavior. Composite hardness models of Korsunsky and Chen-Gao were applied in order to calculate an intrinsic hardness of the coatings and for an assessment of adhesion performance. The corrosion resistance of the Cu coatings was investigated using the “static corrosion test.” A comparative study showed that the Cu coatings produced in ultrasonic agitation regime or in laminate form have better mechanical properties and better corrosion resistance. It has also been shown that Cu coatings synthesized from electrolyte with additives are structurally superior, but a “soft hardening effect” was observed.",
