AB  - Lab-made biosilica (SiO2) nanoparticles were obtained from waste biomass (rice husks) and used as eco-friendly fillers in the production of nickel matrix composite films via the co-electrodeposition technique. The produced biosilica nanoparticles were characterized using XRD, FTIR, and FE-SEM/EDS. Amorphous nano-sized biosilica particles with a high SiO2 content were obtained. Various current regimes of electrodeposition, such as direct current (DC), pulsating current (PC), and reversing current (RC) regimes, were applied for the fabrication of Ni and Ni/SiO2 films from a sulfamate electrolyte. Ni films electrodeposited with or without 1.0 wt.% biosilica nanoparticles in the electrolyte were characterized using FE-SEM/EDS (morphology/elemental analyses, roundness), AFM (roughness), Vickers microindentation (microhardness), and sheet resistance. Due to the incorporation of SiO2 nanoparticles, the Ni/SiO2 films were coarser than those obtained from the pure sulfamate electrolyte. The addition of SiO2 to the sulfamate electrolyte also caused an increase in the roughness and electrical conductivity of the Ni films. The surface roughness values of the Ni/SiO2 films were approximately 44.0%, 48.8%, and 68.3% larger than those obtained for the pure Ni films produced using the DC, PC, and RC regimes, respectively. The microhardness of the Ni and Ni/SiO2 films was assessed using the Chen-Gao (C-G) composite hardness model, and it was shown that the obtained Ni/SiO2 films had a higher hardness than the pure Ni films. Depending on the applied electrodeposition regime, the hardness of the Ni films increased from 29.1% for the Ni/SiO2 films obtained using the PC regime to 95.5% for those obtained using the RC regime, reaching the maximal value of 6.880 GPa for the Ni/SiO2 films produced using the RC regime.

AB  - Developing novel electrocatalysts for energy conversion applications is of utmost importance for reaching the energy security of modern society. Here we present a comprehensive investigation of rhodium-modified polycrystalline nickel as an electrocatalyst for hydrogen and oxygen electrode reactions in alkaline media. The surface modification of nickel electrodes was achieved by facile galvanic displacement (up to 30 s) from a highly concentrated acidic Rh3+ solution. The results demonstrate a significant enhancement in the electrocatalytic activity for both hydrogen evolution reaction (HER) and oxygen evolution reaction (OER) on the Rh-modified Ni electrodes, positioning galvanic displacement as a viable approach to engineering advanced electrocatalysts for clean energy applications. On the other hand, the hydrogen oxidation (HOR) and oxygen reduction reaction (ORR) activities of the Rh-modified electrodes are lower compared to polycrystalline platinum. It is suggested that semiconducting Rh2O3 has a detrimental role on the HOR and ORR performance, while the activities of HER and OER, dominantly taking place on metallic Rh and conductive RhO2, are very high. This research sheds light on the mechanisms underlying the enhanced electrode kinetics on Rh-modified Ni electrodes and provides insights into the development of efficient and cost-effective electrocatalysts for renewable energy technologies.

from biomass (hazelnut shells - HZs). Prepared HZs materials
were carbonized in the furnace at 600° C for 1h, and activated in
CO2 (850 °C, 2h). The microstructural properties of carbons were
tested using the Field-Emission Scanning Electron Microscopy
(FE-SEM) and Brunauer-Emmett-Teller (BET) equation methods.
After shredding, and sifting processes, inert micro-sized particles
were used as bio-reinforcement in electrochemically co-deposited
copper coatings. The sulfate electrolytes without/with carbon
particles (1.0 wt. %) were used for deposition/co-electrodeposition
of 10 micrometers-thick Cu or Cu/C coatings on brass cathodes
using the pulse current regime (PC). The structural, mechanical,
and wettability properties of Cu and Cu/C metal matrix coatings
with variations in amplitude current densities in the range of 30-
100 mA·cm-2 were investigated. An improvement in microhardness
was observed for all Cu/C composites compared to pure Cu
coatings. The wettability resistances of coatings were investigated
using the sessile drop method, and the obtained results are
correlated with the microstructures. The better results were
obtained at a higher current density for the Cu/C coating.

AB  - The lab-made ferrite-aluminium layered double oxide (Fe/Al LDO) nanoparticles were used as reinforcement in the production of copper matrix composite coatings via the electrodeposition route in this study. The Cu coatings electrodeposited galvanostatically without and with low concentrations of Fe/Al LDO nanoparticles were characterized by SEM (morphology), AFM (topography and roughness), XRD (phase composition and texture), Vickers microindentation (hardness), and the static sessile drop method (wettability). All Cu coatings were fine-grained and microcrystalline with a (220) preferred orientation, with a tendency to increase the grain size, the roughness, and this degree of the preferred orientation with increasing the coating thickness. The cross-section analysis of coatings electrodeposited with Fe/Al LDO nanoparticles showed their uniform distribution throughout the coating. Hardness analysis of Cu coatings performed by application of the Chicot-Lesage (C-L) composite hardness model showed that Fe/Al LDO nanoparticles added to the electrolyte caused a change of the composite system from “soft film on hard cathode” into “hard film on soft cathode” type, confirming the successful incorporation of the nanoparticles in the coatings. The increase in roughness had a crucial effect on the wettability of the coatings, causing a change from hydrophilic reinforcement-free coatings to hydrophobic coatings obtained with incorporated Fe/Al LDO nanoparticles.

AB  - Correlation between morphology of electrolytically produced copper thin films and their hardness has been considered. The Cu films were electrodeposited by galvanostatic (DC) and by the pulsating current (PC) regimes on cathodes of limiting values of hardness (Cu, brass, and Si(111)) from the basic sulfate electrolytes without and with addition of leveling/brightening additives, without and with various ways of electrolyte stirring (ultrasound and magnetic stirring), and characterized by scanning electron microscopy (SEM) and atomic force microscopy (AFM) techniques. Hardness of Cu films was determined by microindentation and by application of composite hardness models (CHMs), such as Cheng–Gao (C–G) and Korsunsky (K), with the aim to eliminate a contribution of cathode hardness in the measured film hardness and to determine the absolute hardness of the Cu films. The fine-grained films obtained from the basic sulfate electrolyte were harder than the smooth film obtained from the electrolyte with additives and that obtained by the PC regime, indicating that the PC produced film represents transitional form between these two types of the films. The obtained values of the absolute film hardness in the 1.135–1.647 GPa range were in line with already published values for the electrolytically produced Cu thin films, clearly indicating on successful implementation of CHMs in determination of the absolute hardness of thin films. Correlation between morphology and hardness of Cu films was discussed by the basic laws of electrocrystallization and phenomena on boundary among grains during microindentation processes.

AB  - Metasurfaces are currently among the most attractive research fields, in no small measure due to their usability as refractometric sensors, offering unparalleled sensitivity up to sensing single atoms or molecules. This is rooted in their ability to localize electromagnetic fields in volumes orders of magnitude below the diffraction limit. Numerous materials, both conductive (metals, transparent conductive oxides, graphene, MXenes…) and all-dielectric (oxides, low-loss semiconductors) can be used to build them, thus tailoring metasurfaces, imparting multifunctionalities and enhancing design freedom. However, the fundamental sensing mechanism is practically identical across refractometric platforms – spectral dispersion changes of scattering parameters due to a difference between the real parts of refractive index of the analyte and the environment. Here we describe the use of exceptional capabilities of metasurfaces in transforming optical space to recognize analytes with identical real parts of refractive index but different imaginary parts. We consider a metasurface biosensor with cruciform openings array in an ultrathin silicon layer on silica. We simulate variations of the imaginary part of the effective refractive index in the openings while keeping the real part constant. The circular power flow that increases the optical path, field localization and intrinsically low losses in the optical range jointly cause that adding even the minuscule amounts of analyte with slightly increased optical absorption significantly reduces transmission through the structure, despite its exceptionally low thickness. The described principle can be used to distinguish bio-analytes with identical real part of refractive index like RNA, DNA, proteins, lipids, but also non-biological analytes.

The circular power flow that increases the optical path, field localization and intrinsically low losses in the optical range jointly cause that adding even the minuscule amounts of analyte with slightly increased optical absorption significantly reduces transmission through the structure, despite its exceptionally low thickness. The described principle can be used to distinguish bio-analytes with identical real part of refractive index like RNA, DNA, proteins, lipids, but also non-biological analytes.",

AB  - TiO2 and CeO2 are well known as oxygen sensing materials. Despite high sensitivity, the actual utilization of these materials in gas detection remains limited. Research conducted over the last two decades has revealed synergistic effects of TiO2-CeO2 mixed oxides that have the potential to improve some aspects of oxygen monitoring. However, there are no studies on the sensing properties of the TiO2-CeO2 obtained by mechanochemical treatment. We have tested the applicability of the mechanochemically treated TiO2-CeO2 for oxygen detection and presented the results in this study. The sensing layers are prepared as a porous structure by screen printing a thick film on a commercial substrate. The obtained structures were exposed to various O2 concentrations. The results of electrical measurements showed that TiO2-CeO2 films have a significantly lower resistance than pure oxide films. Mixtures of composition TiO2:CeO2 = 0.8:0.2, ground for 100 min, have the lowest electrical resistance among the tested materials. Mixtures of composition TiO2:CeO2 = 0.5:0.5 and ground for 100 min proved to be the most sensitive. The operating temperature can be as low as 320 °C, which places this sensor in the class of semiconductor sensors working at relatively lower temperatures.

sulfamate baths without/with lab-made biosilica (SiO2) particles on
the Si(100) substrate were produced. Different galvanostatic
regimes were used: direct current (DC), pulse current (PC), and
pulse-reverse current (PRC) regimes. The phase structure of the
synthesized silica nanoparticles from rice husks was obtained using
XRD and FE-SEM. The MMC-Ni/SiO2 and free Ni coatings were
characterized using FE-SEM, AFM, the micro indentation Vickers
technique, and the drop sessile method in order to investigate
structure, roughness, microhardness, and wettability. The optimal
deposition parameters were obtained with an emphasis on their

AB  - Metasurfaces are one of the most attractive research fields in recent years, in no small measure due to their use as refractometric sensors with unparalleled sensitivity, enabling sensing of even single atoms or molecules. This sensitivity is rooted in their ability to localize electromagnetic fields in volumes orders of magnitude below the diffraction limit. This is achieved by special geometry and refractive index contrast of metasurface nanocomposites. A plethora of both conductive (metals, TCO, graphene, MXenes...) and dielectric (oxides, semiconductors) materials can be used, all of them bringing different functionalities which further enhance the freedom of design when tailoring metasurfaces. However, the fundamental sensing mechanism is practically identical across all platforms and is based on the spectral shift of transmission or reflection due to a difference in the values of the real parts of refractive index between analyte and the environment. 
Here we propose an alternative approach, the use of exceptional capabilities of optical metasurfaces in transforming optical space to sense analytes with identical real parts of refractive index but different imaginary parts (losses). This is becoming increasingly important with the need to detect airborne viruses. We propose a metasurface formed by cruciform openings in a thin silicon layer on a SiO2 substrate, as shown in Fig. 1a. The structure is suspended in the air. For our FEM simulation we used measured values for Si and SiO2 refractive index taken from literature. The electric field distribution and its circular power flow, both at a wavelength of 630 nm, are shown in Fig. 1b. We gradually increase the imaginary part of the refractive index in the cruciform openings, starting with the lossless case, while maintaining the real part of refractive index equal to unity (air). The dispersive properties that depend on the value of the imaginary part are shown in Fig. 1c. The circular power flow that increases the optical path, the field localization and intrinsically low losses of the structure in the visible range all cause that adding even the smallest volumes of analyte with slightly increased optical absorption in comparison to the metasurface significantly reduces transmission through the structure, despite the exceptionally low structure thickness.

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.

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  - The present study reports on the preparation of nanocomposites consisting of polyurethane (PU) as the matrix and Ti 3 C 2 T x MXene as the nanofiller, utilizing an in-situ polymerization method. The synthesis parameters of polyurethane remained constant, while the method of adding and preparing MXene was varied. The MXene content was maintained at 1 wt.% for all prepared nanocomposites, and the soft segment content was held constant as well. For the characterization of our materials, FTIR, SEM, TGA and tensile tests were employed. Also, the properties of the prepared nanocomposites were compared to pure PU. FTIR spectra confirmed the formation of urethane bonds. SEM images demonstrated the dispersion state of MXene in the polymer matrix. TGA revealed higher thermal stability of the prepared nanocomposites compared to pure PU. Moreover, the Young’s modulus and tensile strength increased for all prepared nanocomposites.

AB  - MXenes are a relatively new class of 2D nanomaterials with promising properties. The 
functional groups on the surface of the nanosheets play a vital role in interacting with other 
materials, especially in nanocomposites. Biocompatibility, admirable mechanical properties, 
and thermal stability are the most significant properties of poly(dimethylsiloxane)-based 
polyurethanes (PU). They are highly convenient for applications in electronic devices and 
implants. In this study, the MXene content was 1 wt. % for two series and 0.5 wt. % for the 
other two series, while the soft segment content was 50 wt. % for all the series. The 
nanocomposites were obtained using an in-situ polymerization method. The timing of adding 
the MXene nanoparticles to the reaction mixture was also varied to examine the changes in 
the physico-mechanical properties of the nanocomposites. Differential scanning calorimetry 
(DSC), scanning electron microscopy (SEM), and tensile tests were conducted to analyze the 
properties of the resulting materials. The glass transition temperature is highest for the series 
in which MXenes are added in the first phase of polyaddition after the solvation of MDI, 
while the series with 0.5 wt.% MXene added later into the reaction exhibit two transitions. 
SEM images revealed uneven distribution and agglomeration of MXene nanoflakes when 
added into the siloxane prepolymer. The tensile test indicated that the series with 0.5 wt. % 
nanoflakes have significantly lower Young's modulus and tensile strength. The distribution of 
nanoparticles and surface morphology are strongly influenced by the timing of adding the 
MXene dispersion into the reaction mixture, as well as the nanoparticle content.

analyze the maximum temperature achievable on the
microheater and characterize its temperature distribution. The
integrated heater achieved a maximum temperature of 420 °C
with an applied voltage of 16 V. The temperature distribution
was uniform across the entire surface of the heater, which was
located on the underside of the chip beneath the interdigitated
electrodes. At higher temperatures, the silver paste, utilized as
a bonding agent between the copper wires and heater,
underwent melting.

AB  - Polymer-based microelectromechanical systems (MEMS) and devices
are a rapidly expanding field with a wide range of applications, from
microfluidics including lab-on-a-chip systems, to new sensors and
actuators, to flexible and stretchable devices. The use of microfluidic
devices and, more broadly, MEMS structures based on polymer
materials, has increased tremendously due to their great potential in
biomedical, point-of-care, and general healthcare applications.
Currently, polymer materials (elastomers, thermoplastics, and
thermosetting polymers) are commonly used in the fabrication of
microfluidic devices and MEMS structures for their low cost, versatile
fabrication methods, biocompatibility, repeatability, and a wide range of
(customizable) material characteristics with improved functionality.
Polymers have become one of the favored functional materials for microfluidic devices, as they possess excellent mechanical and optical
properties. Furthermore, a variety of polymeric materials with unique
physical and chemical characteristics are also available. Compared to
silicon and glass, polymers are inexpensive, feature a wide variety of
material properties for meeting various application requirements of
disposable biomedical microfluidic devices and MEMS structures, and
have a wide variety of practical applications. In this chapter, different
types of polymer materials used in microfluidics and MEMS devices, the
properties of polymer materials, and the methods for fabricating
polymer-based microfluidic systems and MEMS structures are
described. This chapter highlights the most recent developments, future
trends, and challenges in the devices’ preparation methods, and
applications of polymer-based microfluidic and MEMS devices
generally. Special care has been dedicated to biosensing and applications
where polymer-based microfluidic and MEMS devices allow for new
functionalities: applications based on the use of flexible and stretchable
electronic devices, applications employing novel functional materials
(such as biomimetic scaffold tissues), and advanced sensing mechanisms
(as in plasmonic biosensing). Moreover, this chapter focuses on the
synthesis of polymeric and inorganic nanoparticles in microreactors. The
advantages and limitations of using polymer materials in MEMS
technology are also discussed.

types of polymer materials used in microfluidics and MEMS devices, the
properties of polymer materials, and the methods for fabricating
polymer-based microfluidic systems and MEMS structures are
described. This chapter highlights the most recent developments, future
trends, and challenges in the devices’ preparation methods, and
applications of polymer-based microfluidic and MEMS devices
generally. Special care has been dedicated to biosensing and applications
where polymer-based microfluidic and MEMS devices allow for new
functionalities: applications based on the use of flexible and stretchable
electronic devices, applications employing novel functional materials
(such as biomimetic scaffold tissues), and advanced sensing mechanisms
(as in plasmonic biosensing). Moreover, this chapter focuses on the
synthesis of polymeric and inorganic nanoparticles in microreactors. The
advantages and limitations of using polymer materials in MEMS
technology are also discussed.",

AB  - Polyurethane (PU) nanocomposite materials, offer very desirable advantages over pure PU materials,as the nanocomposites have enhanced thermal, surface, mechanical and biological properties. The main goal of this study was to develop a new kind of novel nanocomposites consisting of crosslinked PUs (based on poly(dimetylsiloxane) and hyperbranched polyester) and ferrite nanoparticles (based on copper and zinc) for possible application as coatings on biomedical devices and implants. A series of PU/ferrite nanocomposites was prepared by in situ polymerization in solution. Characterization of prepared nanocomposites nanocomposites was conducted by Fourier transform infrared spectroscopy (FTIR) and atomic force microscopy (AFM). Copper and zinc releases were investigated by microwave plasma atomic emission spectrometry (MP-AES). Characteristics of the prepared nanocomposites when in contact with a biological environment were examined through testing their biocompatibility, and adhesion of fibroblast cells. The presence of the nanoferrite nanoparticles influenced on surface and biological properties of PU nanocomposites. The prepared PU nanocomposites with noncytotoxic chemistry could be used as promising materials for vascular implants development.

AB  - Self-powered sensors are gaining a lot of attention in recent years due to their possible
application in the Internet of Things, medical implants and wireless and wearable devices. Human
breath detection has applications in diagnostics, medical therapy and metabolism monitoring. One
possible approach for breath monitoring is detecting the humidity in exhaled air. Here, we present an
extremely sensitive, self-powered sensor for breath humidity monitoring. As a power source, the
sensor uses electromagnetic energy harvested from the environment. Even electromagnetic energy
harvested from the human body is enough for the operation of this sensor. The signal obtained using
the human body as a source was up to 100 mV with an estimated power of 1 nW. The relatively low
amount of energy that could be harvested in this way was producing a signal that was modulated by
an interdigitated capacitor made out of electrochemically activated aluminum. The signal obtained
in this way was rectified by a set of Schottky diodes and measured by a voltmeter. The sensor was
capable of following a variety of different respiration patterns during normal breathing, exercise
and rest, at the same time powered only by electromagnetic energy harvested from the human body.
Everything happened in the normal environment used for everyday work and life, without any
additional sources, and at a safe level of electromagnetic radiation.

AB  - Laser-induced graphene (LIG) is one of the most promising graphene-based materials for the
fabrication of flexible electronic devices. However, despite huge efforts to develop LIG on new
substrates there is a lack of stretchable polymers convenient for laser graphenization.
Poly(dimethylsiloxane) is elastomer suitable for flexible electronic fabrication due to excellent
flexibility, optical transparency, hydrophobicity, UV-resistance and good thermal and oxidative
stability. Unfortunately, PDMS cannot be easily graphenized by direct laser writing because of the
low amount of carbon linked to the siloxane chains, mainly consisting of methyl groups. In this
study, a series of PDMS/Triton materials with different concentrations of Triton (1-30 wt.%) was
prepared by casted-based approach starting from divinyl-terminated-PDMS and poly(methylhydrogensiloxane).
Furthermore, direct laser graphenization of PDMS/Triton materials is proposed
for the first time. Different laser parameters and multiple writing steps have been examined in order
to induce a graphene-like structure on PDMS/Triton and to increase as much as possible its
conductivity. The prepared PDMS/Triton/graphene composites were characterized by Raman
spectroscopy, scanning electron microscopy (SEM) and sheet resistance measurements. The results
revealed that by adding Triton it is possible to enhance the graphenization degree. The obtained
PDMS/Triton/graphene composites are suitable candidates for flexible microsupercapacitor
fabrication.

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.
