AB  - Systematic analysis of electrical characteristics of BaCe0.75In0.25O3-δ (BCI25) sintered sample was performed in a
dry and a wet argon atmosphere in the 250 ◦C–700 ◦C temperature range. The water vapor sensing properties of
BCI25 porous film and its response and recovery times were investigated under different conditions of temperature
and water vapor concentration. The 30 μm thick film obtained from the powder calcined at 1050 ◦C
exhibited sensitivity comparable to that of the sintered sample with a significantly shorter response and recovery
times. While the sensitivity of the film gradually decreased with a decrease in partial pressure of water vapor (p
(H2O)), a noticeable sensitivity was still observed at p(H2O) of 200 Pa. Decrease in conductivity depended
logarithmically on the partial pressure of water with the slope of 0.52 that is close to the theoretical value. After
several cycles, the reusability test proved an almost unchanged ratio between the impedance value in the dry and
the wet Ar atmosphere (p(H2O) = 2.34 kPa), which implied that BCI25, having good stability and sensitivity, is a
promising high-temperature humidity sensor.

AB  - Pollen monitoring have become data-intensive in recent years as real-time detectors are deployed

light and laser induced fuorescence. Morphological properties of a particle are sensed with the
light scattering process, while chemical properties are encoded with fuorescence spectrum and
fuorescence lifetime induced by high-resolution laser. By utilizing these three data modalities,
scattering, spectrum, and lifetime, deep learning-based models with millions of parameters are
learned to distinguish diferent pollen classes, but a proper understanding of such a black-box model
decisions demands additional methods to employ. Our study provides the frst results of applied
explainable artifcial intelligence (xAI) methodology on the pollen classifcation model. Extracted

AB  - Varroa destructor is a parasitic mite responsible for the loss of honey bee (Apis mellifera)
colonies. This study aimed to find a promising marker in honey for the bee colony infestation level
using fluorescence spectroscopy and biochemical analyses. We examined whether the parameters of
the honey samples’ fluorescence spectra and biochemical parameters, both related to proteins and
phenolics, may be connected with the level of honey bee colonies’ infestation. The infestation level
was highly positively correlated with the catalase activity in honey (r = 0.936). Additionally, the
infestation level was positively correlated with the phenolic spectral component (r = 0.656), which
was tentatively related to the phenolics in honey. No correlation was found between the diastase
activity in honey and the colonies’ infestation level. The results indicate that the catalase activity in
honey and the PFC1 spectral component may be reliable markers for the V. destructor infestation level
of the colonies. The obtained data may be related to the honey yield obtained from the apiaries.

AB  - Developing highly efficient semiconductor metal oxide (SMOX) sensors capable of accurate and fast responses to environmental humidity is still a challenging task. In addition to a not so pronounced sensitivity to relative humidity change, most of the SMOXs cannot meet the criteria of real-time humidity sensing due to their long response/recovery time. The way to tackle this problem is to control adsorption/desorption processes, i.e., water-vapor molecular dynamics, over the sensor’s active layer through the powder and pore morphology design. With this in mind, a KIT-5-mediated synthesis was used to achieve mesoporous tin (IV) oxide replica (SnO2-R) with controlled pore size and ordering through template inversion and compared with a sol-gel synthesized powder (SnO2-SG). Unlike SnO2-SG, SnO2-R possessed a high specific surface area and quite an open pore structure, similar to the KIT-5, as observed by TEM, BET and SWAXS analyses. According to TEM, SnO2-R consisted of fine-grained globular particles and some percent of exaggerated, grown twinned crystals. The distinctive morphology of the SnO2-R-based sensor, with its specific pore structure and an increased number of oxygen-related defects associated with the powder preparation process and detected at the sensor surface by XPS analysis, contributed to excellent humidity sensing performances at room temperature, comprised of a low hysteresis error (3.7%), sensitivity of 406.8 kΩ/RH% and swift response/recovery speed (4 s/6 s).

AB  - Polycrystalline samples of NaCo2−xCuxO4 (x = 0, 0.01, 0.03, 0.05) were obtained from powder precursors synthesized by a mechanochemically assisted solid-state reaction method (MASSR) and a citric acid complex method (CAC). Ceramic samples were prepared by pressing into disc-shaped pellets and subsequently sintering at 880 °C in an argon atmosphere. Effects of low concentrations of Cu doping and the above-mentioned synthesis procedures on the thermoelectric and mechanical properties were observed. The electrical resistivity (ρ), the thermal conductivity (κ) and the Seebeck coefficient (S) were measured simultaneously in the temperature gradient (ΔT) between the hot and cold side of the sample, and the figure of merit (ZT) was subsequently calculated. The ZT of the CAC samples was higher compared with the MASSR samples. The highest ZT value of 0.061 at ΔT = 473 K was obtained for the sample with 5 mol% of Cu prepared by the CAC method. The CAC samples showed better mechanical properties compared to the MASSR samples due to the higher hardness of the CAC samples which is a consequence of homogeneous microstructure and higher density obtained during sintering of these samples. The results confirmed that, besides the concentration of Cu, the synthesis procedure considerably affected the thermoelectric and mechanical properties of NaCo2O4 (NCO) ceramics.

AB  - In the present work, a biomaterial (SBA-16/HA) based on the growth of hydroxyapatite (HA) particles within an organized silica structure SBA-16 (Santa Barbara Amorphous-16) was developed to evaluate its application to act as a porous microenvironment promoting attachment and viability of human dental pulp stem cells of healthy deciduous teeth (SHED). First, SHED were isolated and their phenotypes were evaluated by flow cytometry. The samples of SBA-16/HA were characterized by X-ray diffraction (XRD), small and wide angle X-ray scattering (SWAXS), Fourier transform infrared spectroscopy (FTIR), and scanning electron microscopy (SEM) equipped with energy dispersive spectra detector (EDS). Afterward, cells were cultured in the eluates of the above-mentioned biomaterial aged for 24 hr, 7. and 14 days. Bio-Oss (R) and dentin particles are involved for comparison and cells are cultured in the eluates of these two materials also. Thiazolyl Blue Tetrazolium bromide assay-MTT (3-(4,5-Dimethylthiazol-2-yl)-2,5-Diphenyltetrazolium Bromide assay) was used for the determination of cell viability. The results obtained by all aforementioned characterization methods of SBA-16/HA, revealed a uniform spherical mesoporous structure, an intrinsic characteristic of this material. This material displayed excellent biocompatibility on SHEDs, and even proliferative potential, indicating that SBA-16/HA could potentially serve as a suitable substrate for bone regeneration. Contrary to SBA-16/HA, dentin particles showed low cytotoxicity at all time points, compared to control and Bio-Oss (R) groups. Our results substantiate the idea that SBA-16/HA has a beneficial effect on SHEDs, thus paving the way toward developing new material for bone replacement.
