AB  - The mechanical activation of the starting mixtures of cordierite (2MgO*2Al2O3*5SiO2) with 5.00 mass % TiO2 was performed in a high energy ball mill during 10-80 min. The applied compaction pressure before the sintering process was 2t/cm2. The sintering process was performed at 1350°C for 2h and 4h in air atmosphere. Scanning electron microscopy was performed to analyze the microstructure of both compacted and sintered samples. Atomic force microscope was used to investigate the surface of the sintered samples. This paper investigates the influence of prolonged sintering time on the densities of the sintered samples, along with electrical properties.

Primenjeni pritisak presovanja pre procesa sinterovanja bio je 2 t/cm2. Proces sinterovanja je izveden na 1350 °C tokom 2h i 4h u vazdušnoj atmosferi. Skenirajuća elektronska mikroskopija je izvršena u cilju analize mikrostrukture presovanih i sinterovanih uzoraka. Za ispitivanje površine sinterovanih uzoraka korišćen je mikroskop atomskih sila.

AB  - Commercially available ZnO powder was mechanically activated in a planetary ball mill. In order to investigate the specific surface area, pore volume and microstructure of non-activated and mechanically activated ZnO powders the authors performed N-2 physisorption, SEM and TEM. Crystallite size and lattice microstrain were analyzed by X-ray diffraction method. XRD patterns indicate that peak intensities are getting lower and expend with activation time. The reduction in crystallite size and increasing of lattice microstrain with prolonged milling time were determined applying the Rietveld's method. The difference between non-activated and the activated powder has been also observed by X-ray photoelectron spectroscopy (XPS). XPS is used for investigating the chemical bonding of ZnO powder by analyzing the energy of photoelectrons. The lattice vibration spectra were obtained using Raman spectroscopy. In Raman spectra some changes along with atypical resonant scattering were noticed, which were caused by mechanical activation.

AB  - In this study, we use the theoretical model of low-frequency noise in an adsorption-based sensor to analyze the possibility for the recognition and quantification of the analyte based on the measured fluctuations spectrum. We have developed an analytical expression for the spectral density of the fluctuations of the number of analyte particles adsorbed onto the sensing surface which takes into account the processes of mass transfer through the sensor reaction chamber, adsorption and desorption, and surface diffusion of adsorbed particles [1,2]. The numerical calculations performed using the derived theory are in agreement with the experimental data from the literature obtained for graphene-based gas sensors [3,4]. While analyzing the dependence of specific features in the fluctuation spectra of various parameters, we investigate which type of information about the analyte and its interaction with the graphene surface can be obtained from the experimentally obtained noise spectrum.

AB  - The authors investigated the morphological characteristics of mechanically activated ZnO powder. ZnO powder was mechanically activated for 2, 5, 10 and 30 minutes in a planetary ball mill. Mechanical activation introduces lattice disorder and defects into ZnO hexagonal wurtzite structure. In order to determine specific surface area and pore volume, we performed N2 porosimetry and SEM in order to investigate the microstructure of non-activated and mechanically activated ZnO powders. Using Kubelka-Munk function, UV-Vis spectra showed the reducing in band gap with activation time. ZnO powder activated for 5 minutes has the narrowest band gap.

AB  - In this study we have developed, for the first time, the comprehensive theoretical model of the fluctuations of the number of adsorbed molecules in MEMS chemical and biological sensors, taking into account the processes of mass transfer, adsorption and desorption, and surface diffusion of adsorbed molecules. It is observed that the shape of the fluctuations spectrum contains information about various parameters of the adsorbed analyte and that even the analytes with the same affinity for the same binding sites have different spectra. The numerical calculations performed using the derived theory show that the influence of surface diffusion on the fluctuations spectrum can be significant. The practical value of this work stems from the fact that the fluctuations of the number of adsorbed molecules can be a dominant noise component in affinity-based bio/chemical sensors. Therefore, the derived theory is useful for development of the methods for the detection of analytes based on frequency domain analysis of the measured fluctuations. The recognition of an adsorbed analyte using sensors with non-functionalized sensing surface will also be considered using the presented theory.

AB  - We have developed a theory of the low-frequency noise caused by interaction of the analyte with the active area of chemical and biological sensors. The main result is an analytical expression for the spectral density of the fluctuations of the number of particles adsorbed onto the sensing surface, taking into account the processes of mass transfer through the sensor reaction chamber, adsorption and desorption, and surface diffusion of adsorbed particles. The performed numerical calculations show good agreement with the experimental data from the literature, obtained for a graphene-based gas sensor. The derived theory contributes to the theoretical basis necessary for the development of a new method for the recognition and quantification of analytes, based on the measured noise spectrum.

AB  - Nanopowder density, as well as compact density, is due to powder particle size, different in their values, compared to micron powders. Also, the technique used for density determination induces large mutual value discrepancies. Scanning electron micrographs of as received powder are presented as an illustration of the shape and size of powder particles and agglomerates. The density of the loose powder pretreated differently was determined using mercury porosimetry and He pycnometry. The methods used for determining the apparent density of the compacts were pycnometry with water as the wetting liquid, mercury porosimetry and also a new approach using a combination of mercury pycnometry along with nitrogen adsorption. Bulk densities of compacts were determined by dimension measurement and mercury pycnometry. Conclusions about nanopowder usage as a charge for dry compaction as well as the most appropriate way for the determination of compact and powder densities are shown.
