AB  - Surfaces of adsorption-based gas sensors are often heterogeneous, with adsorption sites that differ in their affinities for gas particle binding. Knowing adsorption/desorption energies, surface densities and the relative abundance of sites of different types is important, because these parameters impact sensor sensitivity and selectivity, and are relevant for revealing the response-generating mechanisms. We show that the analysis of the noise of adsorption-based sensors can be used to study gas adsorption on heterogeneous sensing surfaces, which is applicable to industrially important liquid-phase exfoliated (LPE) graphene. Our results for CO2 adsorption on an LPE graphene surface, with different types of adsorption sites on graphene flake edges and basal planes, show that the noise spectrum data can be used to characterize such surfaces in terms of parameters that determine the sensing properties of the adsorbing material. Notably, the spectrum characteristic frequencies are an unambiguous indicator of the relative abundance of different types of adsorption sites on the sensing surface and their surface densities. We also demonstrate that spectrum features indicate the fraction of the binding sites that are already occupied by another gas species. The presented study can be applied to the design and production of graphene and other sensing surfaces with an optimal sensing performance.

AB  - U radu prikazan je algoritam koji omogućava primenu 3D štampe u projektovanju ili modifikaciji proizvoda. Aditivna proizvodnja , ili tehnologija 3D štampe, podrazumeva izradu proizvoda složene geometrije u relativno malim količinama. 3D štampa omogućuje realizaciju modela prema digitalnom prikazu, a njena primena je ogromna u različitim proizvodnim granama. Glavne prednosti 3D štampe su: ušteda energije, smanjenje otpada, smanjenje upotrebe većeg broja alata, kao i optimizacija dizajna. Tehnologija 3D štampe radi na principu dodavanja materijala u slojevima. Model se formira od slojeva rastopljenog materijala koji se odmah hladi i očvršćava. Polazni materijal za izradu modela je polilaktična kiselina (PLA). Na mehaničke karakteristike realizovanog modela od PLA utiču različite promenljive kao što su: prečnik brizgaljke, debljina definisanog sloja, procentualna vrednost ispune,geometrija ispune, veličina uzorka, brzina punjenja i temperatura proizvodnje. Cilj ovog rada je da se prikaže algoritam kao deo procedure i aktivnosti kontrole pri realizaciji različitih modela. Time se projektantu daje mogućnost da realizuje nov proizvod, ispravi greške na postojećem proizvodu i na kraju modifikuje proizvod prema zahterima krajnjih korisnika.

U softveru Ultimaker Cura postavlјeni su svi parametri uzorka, dok vizualizaciju dizajna uzorka vrši putanja mlaznica. Mikroskopski pregled strukture ispune pokazao je da postoje određene nepravilnosti u cilјu ispitivanja realizacije i orijentacije slojeva.

AB  - Humidity sensing is important to a variety of technologies and industries, ranging from environmental and industrial monitoring to medical applications. Although humidity sensors abound, few available solutions are thin, transparent, compatible with large-area sensor production and flexible, and almost none are fast enough to perform human respiration monitoring through breath detection or real-time finger proximity monitoring via skin humidity sensing. This work describes chemiresistive graphene-based humidity sensors produced in few steps with facile liquid phase exfoliation followed by Langmuir–Blodgett assembly that enables active areas of practically any size. The graphene sensors provide a unique mix of performance parameters, exhibiting resistance changes up to 10% with varying humidity, linear performance over relative humidity (RH) levels between 8% and 95%, weak response to other constituents of air, flexibility, transparency of nearly 80%, and response times of 30 ms. The fast response to humidity is shown to be useful for respiration monitoring and real-time finger proximity detection, with potential applications in flexible touchless interactive panels.

AB  - Perovskite solar cells (PSCs) have attracted significant attention in recent years due to the rapid increase in device efficiency (reaching over 25% in 2019), ease of fabrication, and the potential to produce low-cost photovoltaic modules. In this paper we have determined the ideal power conversion efficiency and quantum efficiency of PSCs with the p–i–n device structure, where p is the hole transport layer, i is the perovskite absorber layer, and n is the electron transport layer. The absorption of incident light occurs in a thin perovskite layer, the thickness of which is comparable to the wavelength of absorbed light. We take into account interference effects when the PSC structure is represented by a Fabry–Perot resonator. The optical flux within the absorbing layer is calculated as a function of the spatial coordinate (in the direction of the layer thickness), for a certain wavelength, at the normal incident light. The power quantum efficiency is calculated assuming that the incident light source is a blackbody at the temperature of the Sun, as well as for the AM1.5g standard solar spectrum. The results obtained by using the derived expressions that take into account the interference effects are compared with those obtained by neglecting these effects.

We take into account interference effects when the PSC structure is represented by a Fabry–Perot resonator. The optical flux within the absorbing layer is calculated as a function of the spatial coordinate (in the direction of the layer thickness), for a certain wavelength, at the normal incident light. The power quantum efficiency is calculated assuming that the incident light source is a blackbody at the temperature of the Sun, as well as for the AM1.5g standard solar spectrum. The results obtained by using the derived expressions that take into account the interference effects are compared with those obtained by neglecting these effects.",

AB  - Plasmonic materials, stochastically roughened, can provide localized field enhancement under optical irradiation (light trapping). The use of plasmonic materials in semiconductor photocatalists also leads to drastic enhancement of their photoreactivity. Plasmonic enhancement can be seen in an extension of the useful range of solar spectrum, and in a high increase of the amount of collected light energy. The structures we propose here not only can be utilized for a vast majority of photocatalytic systems (including those microreactor-based,) but also for the enhancement of light harvesting devices of any kind, including all types of solar cells, as well as for ultrasensitive chemical sensing. Here we consider a structure with a roughened metallic film on the bottom and a roughened transparent conductive oxide (TCO) or silica glass layer on the top, separated by a thin dielectric layer. We fabricated experimental structures and simulated their electromagnetic properties by the finite element method. Thus we verified that the combined influence of two rough films significantly improves light trapping within the dielectric layer between them, while plasmonic effects lead to concentration of electromagnetic field into subwavelength volumes. Consequently, the radiation intensities are vastly increased within the dielectric layer, even for several orders of magnitude, compared to the incident beam. Another interesting property observed is that while both TCO and silica glass structures act as diffractive light traps well into the UV range, the TCO structure simultaneously acts as a plasmonic superabsorber for IR light, turning the increase of TCO opaqueness with wavelength into a benefit since it significantly expands the useful spectral range. Tuning of dopant levels in TCO or using alternative plasmonic materials, together with varying coarseness of the films can further be used to tailor the electromagnetic response.

The open stub is realized as a double-sided parallel-strip line without a substrate and can be totally immersed into the measured material. It provides high sensitivity of the resonant frequency nearly proportional to the ratio of square roots of dielectric constants of the measured materials. The sensor is tested in two different frequency ranges and for two different dielectric constant ranges (oils and ethanol-water mixture). Its technology is without any additional technological processes such as vias, air-bridges or defected ground structures. Presented sensor is designed, fabricated and tested showing good agreement between simulations and measurements.

AB  - Chemical vapour deposition (CVD) is a promising method for producing large-scale graphene (Gr). Nevertheless, microscopic inhomogeneity of Gr grown on traditional metal substrates such as copper or nickel results in a spatial variation of Gr properties due to long wrinkles formed when the metal substrate shrinks during the cooling part of the production cycle. Recently, molybdenum (Mo) has emerged as an alternative substrate for CVD growth of Gr, mainly due to a better matching of the thermal expansion coefficient of the substrate and Gr. We investigate the quality of multilayer Gr grown on Mo and the relation between Gr morphology and nanoscale mechanical and electrical properties, and spatial homogeneity of these parameters. With atomic force microscopy (AFM) based scratching, Kelvin probe force microscopy, and conductive AFM, we measure friction and wear, surface potential, and local conductivity, respectively. We find that Gr grown on Mo is free of large wrinkles that are common with growth on other metals, although it contains a dense network of small wrinkles. We demonstrate that as a result of this unique and favorable morphology, the Gr studied here has low friction, high wear resistance, and excellent homogeneity of electrical surface potential and conductivity.

AB  - In order to allow for multiscale modeling of complex systems we focus on various approaches to modeling binary adsorption. We consider multiple methods of  modeling the temporal response of general plasmonic sensors. We start from the analytical approach. The kinetics of adsorption and desorption is modeled both as a first order reaction and as a second order reaction. The criteria for their validity and the choice between them in the case of two-component adsorption are established. Due to the nonlinearities of the second order reactions and the lack of their analytical solutions, computer aided modeling is considered next, also in multiple ways: the employment of numerical solvers, fitting of experimental results, the stochastic simulation algorithms and the employment of artificial neural networks (ANN). The examples we present illustrate the advantages and disadvantages of the particular approaches. The goal is to aid the concurrent multiscale modeling of adsorption-based devices. Machine learning in ANN performed here is used to estimate the equilibrium values of adsorbed quantities. The obtained results show that to train an ANN for the estimation of the equilibrium adsorption quantities the Levenberg-Marquardt and the Bayesian regularization algorithms are less efficient than the quasi-Newton BFGS (Broyden-Fletcher-Goldfarb-Shanno) algorithm.

AB  - The objective of this work was to develop low-energy nanoemulsions for enhanced dermal delivery of curcumin, using monoterpene compounds eucalyptol (EUC) and pinene (PIN) as chemical penetration enhancers.  Spontaneous emulsification was the preparation method. All formulations contained 10% of the oil phase (medium-chain triglycerides (MCT), or their mixture with EUC or PIN). Formulations were stabilized by the combination of polysorbate 80 and soybean lecithin (surfactant-to-oil-ratio=1). Concentration of curcumin was set to 3 mg/ml.  Average droplet diameter of all tested formulations ranged from 102 nm to 132 nm, but the ones containing monoterpenes had significantly smaller size compared to the MCT formulation. Such finding was profoundly studied through electron paramagnetic resonance spectroscopy, which proved that the presence of monoterpenes modified the nanoemulsions’ interfacial environment, resulting in droplet size reduction. The release study of curcumin (using Franz cells) demonstrated that the cumulative amount released after 6 h of the experiment was 10.1 ± 0.2% for the MCT nanoemulsions, 13.9 ± 0.1% and 14.0 ± 0.2% for PIN and EUC formulations, respectively. In vivo tape stripping revealed their performances in delivering curcumin into the skin, indicating the following order: EUC>MCT>PIN. The formulation with EUC was clearly the most successful, giving the highest cumulative amount of curcumin that penetrated per surface unit: 34.24±5.68 µg/cm2. The MCT formulation followed (30.62±2.61 µg/cm2) and, finally, the one with PIN (21.61±0.11 µg/cm2). These results corelated with curcumin's solubility in the chosen oils: 4.18±0.02 mg/ml for EUC, 1.67±0.04 mg/ml for MCT and 0.21±0.01 mg/ml for PIN. Probably, higher solubility in the oil phase of the nanoemulsion promoted curcumin's solubility in the superficial skin layers, providing enhanced penetration.

The formulation with EUC was clearly the most successful, giving the highest cumulative amount of curcumin that penetrated per surface unit: 34.24±5.68 µg/cm2. The MCT formulation followed (30.62±2.61 µg/cm2) and, finally, the one with PIN (21.61±0.11 µg/cm2). These results corelated with curcumin's solubility in the chosen oils: 4.18±0.02 mg/ml for EUC, 1.67±0.04 mg/ml for MCT and 0.21±0.01 mg/ml for PIN. Probably, higher solubility in the oil phase of the nanoemulsion promoted curcumin's solubility in the superficial skin layers, providing enhanced penetration.",

AB  - In this contribution we propose, design and numerically analyze a plasmonic metamaterial for enhanced optical absorption, based on 100 nm thick titanium carbide (Ti3C2Tx) MXene sheets. The analyzed metamaterial is built as a sandwich with a solid MXene bottom (ground) layer, a lossless dielectric middle layer and an MXene mesh top layer. The unit cell of the periodic top mesh consists of two crossed ultrathin MXene strips, each of them spreading its width in step-like increments towards the middle of the unit cell. This ensures position-variable width of the top surface apertures, resulting in a widening of the bandwidth of spectral dispersion of the scattering parameters of the obtained metamaterial. We utilize the finite element method to simulate the scattering parameters of the MXene-based metamaterial. We apply Drude–Lorentz model to derive our analytical expression for complex permittivity of Ti3C2Tx MXene based on experimental measurements. The described approach is general, since various alternative plasmonic materials can be utilized, including different MXenes, but other materials as well, such as graphene, metals and metal alloys, semiconductors, etc. The approach is applicable to various other nanoplasmonic structures. In this manner the available toolbox for plasmonics is extended and a new degree of design freedom ensured.

AB  - The multilayer band structure of black phosphorus (BP) is highly anisotropic, and its bandgap is tunable by applying a perpendicular electric field Ez . Within a linear response theory, we study dc and ac transport in few-layer BP, as functions of the Fermi energy, temperature, or frequency,
in the presence of a Zeeman field. The current response to an in-plane electric field along two perpendicular directions is anisotropic and reflects that of the energy spectrum. In addition, we study the Hall conductivity and power absorption spectrum. The Hall
conductivity vanishes, but the power spectrum P(ω) shows a considerable structure as a function of the normalized frequency α/hω=2Δ and/or of the bandgap 2Δ tuned by Ez. In particular, a clear maximum occurs in the difference between spin-up and spin-down contributions
to P(ω). When potassium (K) atoms are deposited on top of BP, the anisotropy in the current response is stronger and the power spectrum is further modified. The results may be pertinent to the development of phosphorene-based applications.

AB  - The BaTiO3 ceramics applications based on electronic properties have very high gradient
scientific and industrial-technological interests. Our scientific research has been based on nano BaTiO3
modified with Yttrium based organometallic salt (MOD-Y). The samples have been consolidated
at a sintering temperature of 1350  C. Within the study, the new frontiers for di erent electronic
properties between the layers of BaTiO3 grains have been introduced. The research target was
grain boundary investigations and the influence on dielectric properties. After scanning electron
microscopy and dielectric measurements, it has been established that modified BaTiO3 samples with
larger grains showed a better compact state that led to a higher dielectric constant value. DC bias
stability was also investigated and showed a connection between the grain size and capacitance
stability. Analyses of functions that could approximate experimental curves were successfully
employed. Practical application of fractal corrections was performed, based on surface ( s) and
pore size ( p) corrections, which resulted in obtainment of the relation between the capacitance and
Curie temperature. Successful introduction of fractal corrections for capacitance-Curie temperature
dependence for a set of experimental data is an important step towards further miniaturization of
intergranular capacitors.

AB  - Nanomembranes represent a versatile novel
building block in micro- and nanoelectromechanical systems,
inspired by biological cell membranes. If built as quasi-2D
multilayer metal-dielectric nanocomposites, they represent a
natural choice for the use in plasmonics and optical
metamaterials, ensuring a new degree of design freedom and
thus a number of new applications.
In this contribution we consider surface sculpting of two types
of three-layer nanomembranes – metal-insulator-metal (MIM)
and insulator-metal-insulator (IMI) structures. The geometry we
analyze represents troughs with ellipsoidal profiles sculpted in
the multilayer nanomembranes, simultaneously acting as
plasmonic waveguides and ensuring tailoring of frequency
dispersion of the plasmonic nanomembranes.
We determine frequency dispersions of the scattering
parameters for the simulated nanomembranes, as well as the
spatial ditribution of the optical near fields in and around them,
both evanescent (plasmon-polariton based) and propagating. To
this purpose we utilize finite element method simulations.
 The obtained results show that our IMI structures exhibit a
behavior similar to that of the EOT arrays, resulting in optical
transparency of the structure for resonant plasmonic modes. On
the other hand, MIM structures offer an excellent confinement of
electromagnetic radiation within the dielectric layer. We
conclude that both MIM and IMI channels allow for additional
degrees of freedom in customization the nanomembrane
evanescent fields, making a way to numerous potential
applications.

AB  - A consideration study for the application of the pressure sensor SP-12 developed and produced by ICTM CMT as an ultrasound sensor is given. The interaction of ultrasound with the sensor’s membrane was analytically described, but for the initial examination of its performance, Finite Elements Method simulation was applied. The sensor SP-12 has eigenfrequencies in the range from 200 kHz to the frequencies higher than 2 MHz. The amplitude of the output signal, which is proportional to Von Mises stress, is highest for the lowest frequency, and it exponentially decreases as the eigenfrequencies increase. This makes the sensor suitable for the ultrasound measurements in the range of hundreds of kHz

abstract = "A consideration study for the application of the pressure sensor SP-12 developed and produced by ICTM CMT as an ultrasound sensor is given. The interaction of ultrasound with the sensor’s membrane was analytically described, but for the initial examination of its performance, Finite Elements Method simulation was applied. The sensor SP-12 has eigenfrequencies in the range from 200 kHz to the frequencies higher than 2 MHz. The amplitude of the output signal, which is proportional to Von Mises stress, is highest for the lowest frequency, and it exponentially decreases as the eigenfrequencies increase. This makes the sensor suitable for the ultrasound measurements in the range of hundreds of kHz",

AB  - In this paper, we present and analyze etching of 
parallelogram patterns in the masking layer on a (100) silicon in 
25 wt % TMAH water solution at the temperature of 80 0C. Sides 
of parallelogram islands in the masking layer are designed along 
<n10> and <100> crystallographic directions. A 3D simulation of 
the profile evolution from these patterns during etching of silicon 
using the level set method is also presented. We determined all
crystallographic planes that appear during etching in the 
experiment and obtained simulated etching profiles of these 3D 
structures. A good agreement between dominant 
crystallographic planes through experiments and simulations is 
obtained.

AB  - A novel concept of vacuum pressure sensor based 
on thin film technology is presented. The sensor is designed as 
a 1 µm thick aluminium film patterned as a structure of 
wedges facing each other along a sharp tip. The distance 
between the wedge tips is 3 µm. This structure is obtained by 
laser writing in vector mode. Parts of the sensor structure are 
fabricated and measured. Analytical consideration of the 
proposed structure is given together with the concept of the 
experimental set up for testing of the sensor

AB  - Magnetic and non-magnetic macroporous crosslinked copolymers of glycidyl methacrylate and trimethylolpropane trimethacrylate were prepared by suspension copolymerization and functionalized with diethylenetriamine. The samples were characterized by mercury porosimetry, scanning electron microscopy with energy-dispersive X-ray spectroscopy (SEM-EDS), Fourier transform infrared spectroscopy analysis (FTIR-ATR), thermogravimetric analysis (TGA), X-ray diffractometry (XRD), atomic force microscopy (AFM), transmission electron microscopy (TEM) and SQUID magnetometry. The FTIR-ATR analysis of synthesized magnetic nanocomposites confirmed the presence of magnetite and successful amino-functionalization. Non-functionalized and amino-functionalized nanocomposites exhibited superparamagnetic behavior at 300 K, with a saturation magnetization of 5.0 emu/g and 2.9 emu/g, respectively. TEM analysis of the magnetic nanocomposite has shown that magnetic nanoparticles were homogeneously dispersed in the polymer matrix. It was demonstrated that incorporation of magnetic nanoparticles enhanced the thermal stability of the magnetic nanocomposite in comparison to the initial non-magnetic macroporous copolymer.

TEM analiza magnetičnog nanokompozita pokazala je da su nanočestice magnetita homogeno dispergovane u polimernoj matrici.
