AB  - Plasmonic  biochemical  sensors,  as  a  subgroup  of  optical  refractometric  sensors,  are  a  topic  of  rapid  research  and  development  due  to  their  ability  to  detect  trace  amounts  of  biochemical agents, even allowing detection of a single molecule. As such, plasmonic sensors find wide  applications  in  forensic  engineering,  medicine  and  clinical  diagnostics,  food  processing,  environmental protection, and many more. Additionally, the use of plasmonic metametrials is not limited to sensing, and they can be used in various fields paramount to forensic sciences, such  as  enhanced  microscopy  and  spectroscopy,  photodetector  enhancement  (entire  optical  range – UV, VIS, and IR light), signal processing, etc.

AB  - In this study, a novel procedure, based on application of the Chicot–Lesage (C–L) composite hardness model, was proposed for the determination of an absolute hardness of electrolytically produced copper coatings. The Cu coatings were electrodeposited on the Si(111) substrate by the pulsating current (PC) regime with a variation of the following parameters: the pause duration, the current density amplitude and the coating thickness. The topography of produced coatings was characterized by atomic force microscope (AFM), while a hardness of the coatings was examined by Vickers microindentation test. Applying the C–L model, the critical relative indentation depth (RID)c of 0.14 was determined, which is independent of all examined parameters of the PC regime. This RID value separated the area in which the composite hardness of the Cu coating corresponded to its absolute hardness (RID <0.14) from the area in which the application of the C–L model was necessary for a determination of the absolute coating hardness (RID ≥ 0.14). The obtained value was in a good agreement with the value already published in the literature.

Ова вредност раздваја област у којој композитна тврдоћа превлаке може да се изједначи са њеном апсолутном тврдоћом (RID << 0,14) од области у којој је неопходно применити C–L модел за одређивање апсолутне тврдоће превлаке (RID ≥ 0,14).

AB  - In this study, a basic sulfate electrolyte for electrochemical copper deposition and a sulfate electrolyte with additives to improve coating quality were used. It has been shown that for the visualization of latent fingerprints, it is better to use an electrolyte without additives. The use of electrolytes with additives has not been shown to be adequate for these purposes due to the effect of filling fingerprint ridges and reducing contrast.

AB  - In this investigation, nickel coatings were electrodeposited on brass substrate. The effects of 
electrodeposition process parameters such as, current density and deposition time (coatings thickness), on surface morphology and composite hardness values were studied. The 
value of the measured composite hardness by Vickers microindentation technique of the selected “hard film on soft substrate” composite system type depends on the applied indentation loads. For this reason, the microindentation loads are also included in the analysis. According to the experiment plan obtained by Design-Expert software, nickel coating has been produced on the brass cathode using galvanostatic regime (DC) with magnetic stirring of the electrolyte. The nickel 
sulphamate electrolyte with saccharine additive was used for Ni electrodeposition. Then, response surface methodology (RSM) was used to establish an adequate mathematical model. Subsequently, a mathematical model was developed to weight the effects of each input parameters (coating thickness, current density and indentation load) on the output parameter (composite hardness) of electrodeposited nickel coatings on brass substrate. According to the obtained results, the coating thickness and indentation load greatly influenced resulting composite hardness. On the other hand, coating current density primarily influenced microstructure and surface roughness. The topographic modification of the Ni coating surface depending on the post-treatment (mechanical and chemical) after deposition was studied using AFM microscopy.

AB  - The influence of various intensities of ultrasound applied for the electrolyte stirring on morphological and mechanical characteristics of electrolytically produced copper coatings has been investigated. The copper coatings produced by the galvanostatic regime of the electrodeposition from the basic sulphate electrolyte and the electrolyte with added levelling/brightening additives at the low temperature were characterized by scanning electron microscopy (SEM) and atomic force microscopy (AFM) techniques (surface morphology and topography, respectively) and by Vickers microindentation (hardness). The roughness of coatings increased with the increasing intensity of ultrasound, indicating that morphology of the coatings worsened with the enhanced application of ultrasonic waves. This is attributed to the strong effect of ultrasound on hydrodynamic conditions in the near-electrode layer, which is manifested by the increase of share of the activation control in the mixed activation-diffusion control of electrodeposition with increasing the intensity of ultrasound. The concept of "effective overpotential" originally proposed to explain a change of surface morphology in the conditions of vigorous hydrogen evolution is also applicable for a change of morphology of Cu coatings under the imposed effect of ultrasonic waves. Hardness analysis of the coatings showed that an intensity of applied ultrasound did not have any significant effect on the hardness, especially for the Cu coatings produced from the basic sulphate electrolyte.

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.

AB  - Mechanical (hardness and adhesion) and electrical (sheet resistance) characteristics of electrolytically produced copper coatings have been investigated. Morphologies of Cu coatings produced galvanostatically at two current densities from the basic sulfate electrolyte and from an electrolyte containing levelling/brightening additives without and with application of ultrasound for the electrolyte stirring were characterized by SEM and AFM techniques. Mechanical characteristics were examined by Vickers microindentation using the Chen–Gao (C–G) composite hardness model, while electrical characteristics were examined by the four-point probe method. Application of ultrasound achieved benefits on both hardness and adhesion of the Cu coatings, thereby the use of both the larger current density and additive-free electrolyte improved these mechanical characteristics. The hardness of Cu coatings calculated according to the C–G model was in the 1.1844– 1.2303 GPa range for fine-grained Cu coatings obtained from the sulfate electrolyte and in the 0.8572–1.1507 GPa range for smooth Cu coatings obtained from the electrolyte with additives. Analysis of the electrical characteristics of Cu coatings after an aging period of 4 years showed differences in the sheet resistance between the top and the bottom sides of the coating, which is attributed to the formation of a thin oxide layer on the coating surface area.

AB  - Electrodeposition of Cu was performed on Si(111) by the pulsating current (PC) regime in the
range of the average current densities (jav) between 15 and 70 mA cm-2
. The selected values of the
average current densities were attained by varying either pause duration (tp: 28.3, 15, 7.5 and 5 ms,
i.e. jav: 15, 25, 40 and 50 mA cm-2
for the constant values of deposition pulse of 5 ms and current
density amplitude (jA) of 100 mA cm-2) or amplitude of the current density (jA: 120 and 140 mA cm-2
,
i.e. jav: 60 and 70 mA cm-2
for the constant values of deposition pulse of 5 ms and pause duration of
5 ms). Morphological and structural characteristics of the obtained coatings were examined by
scanning electron microscope (SEM), atomic force microscope (AFM) and X-ray diffraction (XRD),
respectively. With increasing the average current density, morphologes of the coatings changed from
those with large and well defined crystal grains obtained at jav of 15 mA cm-2 (the dominant effect of
activation control) to fine-grained obtained at jav of 50 mA cm-2 (the mixed activation-diffusion
control) and those with globules when diffusion becomes a dominant process (jav = 70 mA cm-2). The
minimum roughness showed the Cu coating obtained at jav of 50 mA cm-2
. Simultaneously, crystal
structure changed from the strong (220) to the strong (111) preferred orientation with increasing
average current density. The change of surface morphology was discussed by the effect of applied
parameters of the PC regime on the type of electrodeposition control, while change in crystal
orientation of produced coatings was explained by various rates of growth on various crystal planes.
Hardness analysis of the produced coatings was performed by application of the Chicot-Lesage (C-L)
composite hardness model. By application of this model, the relative indentation depth (RID; where
RID = h/d; h is an indentation depth, and d is a thickness of coating) of 0.14 was established as the
limiting value separating the area of the absolute hardness of the Cu coatings (RID < 0.14) from the
area in which application of the C-L model is necessary for a determination of the absolute hardness
of coatings (RID > 0.14). For RID < 0.14, the measured composite hardness corresponded to the
absolute hardness of the coating.

AB  - The mechanical characteristics of electrochemically deposited copper coatings have been
examined by application of two hardness composite models: the Chicot-Lesage (C-L) and the Cheng-Gao (C-G) models. The 10, 20, 40 and 60 microns thick fine-grained Cu coatings were electrodeposited on the brass by the regime of pulsating current (PC) at an average current density of 50 mA cm-2, and were characterized by scanning electron (SEM), atomic force (AFM) and optical (OM) microscopes. By application of the C-L model we determined a limiting relative indentation depth (RID) value that separates the area of the coating hardness from that with a strong effect of the substrate on the measured composite hardness. The coating hardness values in the 0.9418–1.1399 GPa range, obtained by the C-G model, confirmed the assumption that the Cu coatings on the brass belongs to the "soft film on hard substrate" composite hardness system. The obtained stress exponents in the 4.35–7.69 range at an applied load of 0.49 N indicated that the dominant creep mechanism is the dislocation creep and the dislocation climb. The obtained mechanical characteristics were compared with those recently obtained on the Si(111) substrate, and the effects of substrate characteristics such as hardness and roughness on the mechanical characteristics of the electrodeposited Cu coatings were discussed and explained.

AB  - The influence of various electrolysis parameters, such as the type of cathode, composition of the electrolyte and electrolysis time, on the morphology, structure and hardness of copper coatings has been investigated. Morphology and structure of the coatings were analyzed by scanning electron microscope (SEM), atomic force microscope (AFM) and X-ray diffraction (XRD), while coating hardness was examined by Vickers microindentation test applying the Chicot–Lesage (C–L) composite hardness model. Depending on the conditions of electrolysis, two types of Cu coatings were obtained: fine-grained mat coatings with a strong (220) preferred orientation from the sulfate electrolyte and smooth mirror bright coatings with a strong (200) preferred orientation from the electrolyte with added leveling/brightening additives. The mat coatings showed larger both measured composite and calculated coating hardness than the mirror bright coatings, that can be explained by the phenomena on boundary among grains. Independent of electrolysis conditions, the critical relative indentation depth (RID) of 0.14 was established for all types of the Cu coatings, separating the zone in which the composite hardness can be equaled with the coating hardness and the zone requiring an application of the C–L model for a determination of the absolute hardness of the Cu coatings.

AB  - Influence of an intensity of ultrasonic mixing of electrolyte in a temperature range of 27–37 °C and ultrasonic power intensity in the range of 3.77–18.84 W/cm2 (10–50 %) on a synthesis of fine-grained copper deposits was examined. Copper coatings were electrodeposited on a brass substrate in direct current (DC) regime with an applied current density of 50 mA·cm-2. The laboratory-made copper sulfate electrolyte was used without or with addition of additives. The variation of temperature under sonoelectrodeposition process and variation mixing intensity of electrolyte were ensured by using an ultrasonic probe. The produced Cu coatings were examined by optical microscope (OM) in order to observe the microstructural modification with variation ultrasonic parameters and for measuring imprints of Vickers indenter. The micro hardness properties of composite systems were characterized using Vickers micro indentation test. The composite hardness models Chicot-Lesage and Chen-Gao were used for the determination the coatings hardness and adhesion evaluation. Application of Atomic Force Microscopy (AFM) technique also confirmed the strong influence of ultrasonic mixing conditions of electrolyte onto change of the microstructure of copper deposits and surface roughness of the coatings. The maximum hardness, good adhesion properties and minimum micro surface roughness was obtained for the fine-grained Cu coating produced with amplitude of 50 % ultrasonic mixing of electrolyte without additives and 30 % for electrolyte with additives.

AB  - Copper coatings are produced on silicon wafer by electrodeposition (ED) in pulsating current (PC) regime. Electrodeposition was performed at various current density amplitudes in the range of 80−140 mA cm-2, frequency in the range of 30−100 Hz and coating thickness in the range of 10−60 μm. The resulting composite systems consist of monolayered copper films electrodeposited from sulfate bath on Si wafers with sputtered layers of Cr/Au. Roughness measurements were performed to evaluate properties of the copper coating surface. The coating roughness (R) was measured using Atomic Force Microscope in contact mode. The software Gwyddion was used for determination an average roughness parameter (Ra). After that (Artificial Neural Network-ANN) model was used to study the relationship between the parameters of electrodeposition process and roughness of copper coatings. The influence of experimental values: amplitude current density, frequency and thickness of coating on the surface roughness will be highlighted. Response surface methodology (RSM) was utilized to improve the correction between Ra and input parameters. Finally, the results of the average roughness (experimental and predicted) were used to estimate the new value of (Ra) of copper for each variation of the input parameters and compared capability of ANN and regression analysis for surface roughness generated under different electrochemical conditions. The coefficient of determination was found 92% for ANN and 93% for regression analysis.

AB  - Mechanical features of the Cu coatings produced by the pulsating current (PC) regime on Si(111)
substrate have been investigated. The Cu coatings were electrodeposited by varying duty cycle (15−50 %) and keeping the current density amplitude constant (100 mA cm−2), and by keeping duty cycle constant (50 %) but varying the current density amplitude value (80−120 mA cm−2). The scanning electron microscopy (SEM) and optical microscopy (OM) techniques showed that morphology of the coatings changed with increasing the duty cycle from those with large and well defined grains to uniform and compact fine-grained coatings. The Vickers microindentation technique was used for an examination of hardness applying the Chen-Gao (C-G) composite hardness model and indentation creep features of the Cu coatings. The obtained values of hardness for the Cu coatings on Si(111) in the 0.9069−1.5079 GPa range indicated the successful implementation of the C-G model for this "soft film on hard substrate" composite system. The obtained stress exponents ranging from 2.79 to 5.29 indicated that creep mechanism changed from grain boundary sliding to both dislocation climbs and dislocation creep with decreasing duty cycle values. The maximum hardness and minimum stress exponent was obtained for the fine-grained Cu coating produced with a duty cycle of 50 % and the current density amplitude of 100 mA cm-2, indicating that its plastic deformation during microindentation was primarily caused by grain boundary sliding. Optimization of process formation and mechanical features of the Cu coatings was made using Response Surface Methodology (RSM), and error of 3.2 % showed a good agreement between predicted and measured values.

AB  - Fine-grained nickel coatings were electrodeposited by direct current (dc) regime
onto different substrates: polycrystalline cold-rolled copper, polycrystalline brass and single
crystal (100)-oriented silicon. These composite structures belong to different type of laminated
composite systems. The influence of the substrate material and coating plating parameters on
microstructural and mechanical properties, such as hardness and adhesion, was characterized by the Vickers microindentation test for different loads. Above critical indentation depth (usually
around 10% of the coating thickness), the measured hardness is the so-called “composite
hardness”, because the substrate participates in the plastic deformations during indentation.
Three composite hardness models (Korsunsky, Chicot-Lesage and Chen-Gao), constructed on
different principles, were chosen for fitting the experimental results in order to determine the
coating hardness and the critical reduced depth as the adhesion parameter. The coating hardness
is mainly influenced by the current density, because increase in current density leads to decrease
in grain size and increase in coating hardness. The critical reduced depth as the parameter of
adhesion depends on the substrate material.

AB  - Copper electrodeposition on (111)-oriented Si substrate was performed by the pulsating current (PC) regime at various average current densities in the range of 15–70 mA·cm−2, obtained by varying either the frequency (30, 50, 80 and 100 Hz for the current density amplitude of 100 mA·cm−2) or the current density amplitude (120 and 140 mA·cm−2 at 100 Hz). The produced Cu coatings were examined by SEM, AFM and XRD techniques. The morphology of the coatings changed from those with large grains to fine-grained and globular, while the crystal structure changed from the strong (220) to the strong (111) preferred orientation by increasing the average current density. The mechanical characteristics of coatings were examined using Vickers micro-indentation tests, applying the Chicot–Lesage (C–L) composite hardness model for the analysis of microhardness. The maximum microhardness was obtained for the Cu coating produced at an average current density of 50 mA·cm−2, with a current density amplitude of 100 mA·cm−2 and a frequency of 100 Hz. This copper coating was fine-grained and showed the smallest roughness in relation to the other coatings, and it was obtained in the mixed activation–diffusion control between the end of the effect of the activation control and the beginning of the dominant effect of diffusion control.

AB  - The mechanical properties of systems consisting of copper coatings
electrodeposited on both brass sheet (BS) and thick electrodeposited nickel
coating (ED Ni) substrates have been investigated. The electrodeposition of
copper coatings was performed with and without the ultrasound assistance. The
ultrasound application decreases root mean square (RMS) roughness of deposited Cu coating on both applied substrates, as obtained from non-contact
AFM measurement. The coating roughness is highly dependent on the substrate roughness, being the smallest for the Cu coatings deposited on ED Ni
substrate with the ultrasound mixing. The hardness and adhesion properties
were characterized using the Vickers microindentation test. Model of Korsunsky was applied to the experimental data for determination the film hardness and the model of Chen-Gao was used for the adhesion evaluation. The
introduction of ultrasonic agitation caused the changes in the film microstructure, and consequently in the mechanical properties. The copper coatings on
both substrates, have higher hardness when deposited from electrolyte with
ultrasound agitation. Although the type of the substrate has the major influence
on the adhesion strength, it can be said that Cu electrodeposition with ultrasonic mixing contributes to an increase in adhesion

AB  - Copper coatings are produced on silicon wafer by electrodeposition (ED) for various cathode current densities. The resulting composite systems consist of 10 μm monolayered copper films electrodeposited from sulphate bath on Si wafers with sputtered layers of Cr/Au. Hardness measurements were performed to evaluate properties of the composites. The composite hardness (H c ) was characterized using Vickers microindentation test. Then, an artificial neural network (ANN) model was used to study the relationship between the parameters of metallic composite and their hardness. Two experimental values: applied load during indentation test and current density during the ED process were used as the inputs to the neural network. Finally, the results of the composite hardness (experimental and predicted) were used to estimate the film hardness (H f ) of copper for each variations of the current density. This article shows that ANN is an useful tool in modeling composite hardness change with variation of experimental parameters predicting hardness change of composite Si/Cu with average error of 6 %. Using created ANN model it is possible to predict microhardness of Cu film for current density or indentation load for which we do not have experimental data.

AB  - TiO2-CeO2 nanopowders were synthesised by a ball-milling process and then annealed at temperatures from 500 degrees to 800 degrees C. X-ray diffraction and diffuse reflectance spectra were used in combination with temperature programmed desorption to determine the structural and microstructural changes of nanopowders as a the function of annealing temperature. The results of the X-ray analysis showed that the weight fraction of the cerianite phase remained unchanged with a temperature rise of 600-700 degrees C, indicating that the phase changes occur only within TiO2. The TiO2-CeO2 nanopowder showed enhanced optical properties with a red shift after the thermal treatment. Photocatalytic studies revealed that the sample annealed at 600 degrees C showed higher photocatalytic activity than samples annealed at lower or higher temperatures in the degradation of the methyl orange. The activity test of all samples is in accordance with photoluminescence measurements, proportional to the concentrations of hydroxyl radicals at the photocatalyst surfaces.
