AB  - BiFeO3 powders were synthesized by sonochemically assisted hydrothermal and hydro-evaporation methods. The X-ray diffraction confirmed the presence of secondary phases, Bi25FeO39 and Bi2Fe4O9, in as prepared BiFeO3 powders. Optimization of sintering conditions indicated that temperature of 800 °C and time of 2 h after pressing at 9 t/cm2 provided ceramics samples with the highest density (up to 96% of theoretical density) and the lowest content of secondary phases. Ferroelectric and magnetic characterization was performed on two selected ceramics samples with the highest densities. Ceramics obtained from the powder synthesized by the hydrothermal method showed greater lattice distortion along [1 1 1] axis and smaller grains, which resulted in larger values of electric polarization at room temperature. It also exhibited less Fe(3d)–O(2p) orbital overlapping due to a larger FeOFe bond angle, causing lower antiferromagnetic ordering and weak ferromagnetic behavior at low temperatures.

AB  - Spinel materials based on Mn and Ni has been intensively studied over the past years due to their excellent semiconductor properties. Nickel manganite as NTC thermistor is widely used today in different industrial sectors. Here we report the complex polymerization method (CPM) for producing nickel manganite fine particles with a homogeneous distribution of constituent cations in the crystal lattice that ensures formation of dense monophased ceramic with the novel magnetic properties after been sintered in oxygen and air atmosphere. Phase composition of the synthesized materials was examined by XRPD, while the morphology of the powder and microstructure of ceramic were investigated using FESEM and SEM analyses, respectively. The magnetic properties of the samples have been studied by measuring the temperature and field dependence of magnetization. Magnetic measurements of M(T) reveal rather complex magnetic properties and multiple magnetic phase transitions. In the case of air atmosphere we found three magnetic phase transitions with transition temperatures at TM1=35 K, TM2=101 K and TM3=120 K. TM1 maximum is strongly dependent on the strength of the applied magnetic field (TM1 decreases with increasing applied field) whereas the TM3 is field independent The values of the coercivity, remanent magnetization and saturation magnetization at 100 K are: HC = 184 Oe, Mr = 1.92 emu/g and MS = 7.88 emu/g, respectively. The measured values at 5 K are HC = 1035 Oe, Mr = 7.70 emu/g and MS = 14.47 emu/g. Moreover, hysteresis properties measured after cooling of the sample in magnetic field show exchange bias effect with an exchange bias field |HEB=196 Oe. For the sample synthetized in oxygen atmosphere, the magnetization dependence of temperature M(T) and AC susceptibility data obtained from SQUID measurements clearly demonstrates that quadruple magnetic phase transitions can be readily detected at TM1~115 K, TM2~105 K, TM3~38 K and TM4~7 K. These findings suggest the novel magnetic transition for nickel manganite at low temperature TM4. The temperatures of observed maximums in χ’(T) and χ’’(T) parts of susceptibility are frequency independent, whereas the height of the peaks decreases with increasing frequency. The fact that TM4 does not shift with the increase of the frequency led us to the conclusion that there are no spin-glass/surface effect and/or blocking temperature/finite size effect connected to the NiMn2O4 ceramic. Therefore, the low-temperature peak TM4 in AC susceptibility is associated with ferromagnetic-like and antiferromagnetic-like magnetic transition in the interfacial FM/AFM internal structure. The exchange bias effect was found in a field cooled hysteresis loops at 5 K. The field cooling of the sample was under a magnetic field of 100 Oe and 10 kOe whereas the determined exchange bias fields were |HEB|=129 Oe and 182 Oe, respectively. The analysis of the results and comparison with literature data allowed us to conjecture that the mixed oxidation states of Mn ions and ferromagnetic and antiferromagnetic sublattice orders tailor these interesting magnetic properties.

AB  - One of the major challenges in the development of nanocomposites based on a polymer matrix and highly polar ceramic nanofillers is the lack of the compatibility between these two components. In order to improve the chemical interaction between titanate nanotubes (TTNT) and polymer matrix, such as nylon 11,3-aminopropyltriethoxysilane (APTES) was grafted onto TTNT. The effects of the TTNT chemical composition i.e. sodium content and solvent type on the grafting silane efficiency were thoroughly studied through CHN elemental analysis, Fourier transform infrared spectroscopy (FTIR), thermogravimetric analysis (TGA), transmission electron microscopy (TEM), surface area and zeta potential measurements. The present study brings evidences supporting aqueous ethanol as more efficient reaction medium for TTNT functionalization with APTES, independent of the sodium content of nanotubes, when compared with pure water. It is also worth noting that within aqueous ethanol medium, TTNT with low sodium content are more efficiently grafted than TTNT with high sodium content. Successful APTES grafting decreases concentration of the hydroxyl groups on TTNT surfaces and enables its future application for the fabrication of nylon 11 nanocomposites.

AB  - The purpose of the present study was to investigate the effect of titanate nanotubes (TINTs) dispersion in the mechanical properties of Nylon 11 (polyamide 11) polymer. According ,to the existing literature small amounts of TTNTs used as reinforcement in polymer matrix improve properties such as tensile strength and stiffness. However, the addition of these nanoparticles may also lead to a decrease of strength of the composite if the nanotubes are not well dispersed in the polymer matrix. In this work two different routes were investigated to enhance the disl?ersion of TTNTs used as a reinforcement of nylon matrix nanocomposites: (1) chemical functionalization with 3-arninopropyltriethoxysilane; and (2) treatment with 2 kinds of surfactant - a cationic (CTAB) and an anionic (SDS). Characterization of the nanotubes was done by infrared spectroscopy, CHN elemental analysis, measurement of the specific surface area, thermogravimetric analysis, scanning electron microscopy and transmission electron microscopy. Nylon-II matrix nanocomposites were manufactured by microextrusion-microinjection and reinforced with 0.5 to 2.0 wt.-% of functionalized and surfactant treated nanotubes. Finally, mechanical and thermal properties as well as the microstructure of the nanocomposites were evaluated. The presentation will discuss the results and potential applications of these materials.

Nylon-II matrix nanocomposites were manufactured by microextrusion-microinjection and reinforced with 0.5 to 2.0 wt.-% of functionalized and surfactant treated nanotubes. Finally, mechanical and thermal properties as well as the microstructure of the nanocomposites were evaluated. The presentation will discuss the results and potential applications of these materials.",

AB  - In order to develop new nanosized filler compatible with the thermoplastic polymer Nyion-11, trititanate nanotubes (TTNTs) were synthesized by standard alkaline hydrothermal treatment of a TiO2 anatase powder in 10 M NaOH at 120 DC for 24 h. After the synthesis, the as-obtained nanopowder was washed differently (either with water or HC1), in order to prepare TTNTs with high and low sodium contents. Chemical functionalization of TTNTs was performed with 3-minopropyltriethoxisilane (APTES) coupling agent using two different reaction media (water and an ethanol/water mixture) with the aim to improve the bonding between inorganic hydrophilic fillers and hydrophobic polymer matrix. Fourier transform infrared spectroscopy (FTIR), thermogravimetry analysis (TGA), transmission electron microscopy (TEM), zeta potential and CHN elemental analyses were used to elucidate the grafting mechanism of APTES at TTNTs surface. The obtained results shown that: APTES coupling agent is bounded covalently to the TTNTs surface (Ti-O-Si bond was identified after deconvolution of the IR bands at 800-1000 cm-1); grafted amount of APTES is almost independent of the reaction media; protonation of-NH2 groups shift the isoelectric point from pH 2.4 to pH 6.6; TTNTs kept their original size and shape after silanization.

AB  - Intrinsic resistivity and carrier transport parameters of sintered nickel manganite samples (NTC thermistor grade) were determined using a Hall effect measurement system based on the van der Pauw method. Powder mixtures composed of MnO, NiO and with small amounts of CoO and Fe 2O 3 were free surface energy activated by milling in an ultra fast planetary mill for 5, 15, 30, 45 and 60 min. The powders were uniaxially pressed with 196 MPa into discs and sintered at 1200 °C for 60 min. Full characterization of nickel manganite samples was done using SEM, EDS and XRD analysis. The Hall effect was measured at different temperatures (room temperature, 50, 80, 100 and 120 °C) with an applied field of 0.37 T and also 0.57 T at room temperature. The activation energy E a (energy of conduction) and the coefficient of temperature sensitivity B 25/80, were calculated from measured resistivity values. The measured mobility, resistivity/conductivity, U-I plots, and Hall coefficients were mutually compared and correlated versus microstructure development and macroscopic parameters such as the powder activation time and ambient temperature. © Springer Science+Business Media, LLC 2008.

AB  - A single p-type crystal of the mineral, pyrite (FeS2) was characterized photoacoustically using the transmission detection configuration. Photoacoustic (PA) amplitude and phase spectra were measured using a specially constructed PA cell. The PA signals of different sample thicknesses were measured using an experimental setup with a semiconductor red laser (80 mW) as the optical source. The obtained amplitude and phase spectra for different thicknesses were numerically analyzed enabling determination of thermal diffusivity, mobility of minority free carriers and other parameters characteristic for this material. © EDP Sciences/Societé Italiana di Fisica/Springer-Verlag 2008.

abstract = "A single p-type crystal of the mineral, pyrite (FeS2) was characterized photoacoustically using the transmission detection configuration. Photoacoustic (PA) amplitude and phase spectra were measured using a specially constructed PA cell. The PA signals of different sample thicknesses were measured using an experimental setup with a semiconductor red laser (80 mW) as the optical source. The obtained amplitude and phase spectra for different thicknesses were numerically analyzed enabling determination of thermal diffusivity, mobility of minority free carriers and other parameters characteristic for this material. © EDP Sciences/Societé Italiana di Fisica/Springer-Verlag 2008.",

AB  - Zinc-titanate ceramics were obtained by initial mechanical activation in a high-energy planetary mill for 15 min followed by sintering at temperatures 900-1100°C for 2 h. Room temperature far infrared reflectivity spectra for all samples were measured in the range 100-1200 cm-1. The same ionic oscillators were present in the measured spectra, but their intensities increased with the sintering temperature in correlation with the increase in sample density and microstructure changes. Optical parameters were determined for seven oscillators belonging to the spinel structure using the four-parameter model of coupled oscillators.

AB  - A novel uniaxial anemometer was created using a NTC thick film segmented thermistor to measure wind speed and direction. The anemometer operated on the principle of heat loss caused by the air volume flow and air speed. A NTC segmented thermistor served as a wind sensor in the anemometer. It was self-heated by a DC constant voltage. The self-heated DC current through the thermistor was changed by heat loss due to resistivity changes. The wind speed was varied from 1 to 15 m/s for different input air temperatures in the range of -20 to +40°C. The wind direction was determined by measuring voltage differences on the inner electrodes of the NTC segmented thermistor. The air temperature was measure by a cold NTC thick film segmented thermistor calibrated in the claim chamber. Anemometar inertia was measured at room temperature (at 25°C) and normal room humidity (at 50%). The results obtained enable fast optimization and implementation of a uniaxial anemometer in a 3D anemometer. © 2008 IEEE.

AB  - In this work the DC resistivity of sintered nickel manganite NiMn2O4 (NTC thermistor material) was studied as a function of additional powder activation time in a planetary ball mill (0, 5, 15, 30, 45 and 60 min). The activated powders and non-activated powder were sintered at different temperatures (900, 1050 and 12000C) for an hour. Structural changes were analyzed using XRD. Sample density, porosity and DC resistivity were measured on the same sintered samples. Correlations between sample density, porosity, and intrinsic DC resistivity vs. additional powder activation time and the sintering temperature were made. It was noticed that the resistivity falls with the increase of sample density (or increase of the sintering temperature).

AB  - Single crystals of PbTe(Ni) were investigated by the photoacoustic method. They were produced using the Bridgeman method. These crystals have a sodium chloride cubic lattice and could be cleaved paralel to the plane orientation (200). They were of the n-type. Phase and amplitude photoacoustic spectra were measured using a transmision detection configuration set-up. Photoacoustic (PA) spectra (single and normalized) were numerically analyzed using the Rosencwaig-Gersho model. Thermal diffusivity and some electron-transport parameters were determined. These results were compared with existing results for pure single crystal PbTe. Thermal difusivity of PbTe(Ni) is a bit higher than the thermal difusivity of pure PbTe. This is the consequence of a decreasing concentration of the majority free carriers in the doped alloy.

Small disc shaped pills of the powder obtained were made by pressing with a pressure of 2.5 MPa. The pills were sintered in the temperature range of 900-1400 °C for 30-240 min. The volume and specific volume resistivity change were measured as a function of sintering conditions. Microstructure development was observed using a SEM microscope. Using the results obtained, optimization of sintering parameters was performed in order to determine optimal electrical properties of the selected thermistor composition.

AB  - NTC termistori na bazi Mn, Ni, Co i Fe oksida za potrebe debeloslojnih senzora pripadaju oblasti istraživačkog i primenjenog rada sa ciljem realizacije senzora prilagođenih po obliku, prenosu toplote i brzini odziva fizičkim veličinama koje treba da mere. Tako npr. brzi senzori temperature zahtevaju konstrukcije debeloslojnih termistora što manje debljine i podloge koje slabo provode toplotu: inercija tih senzora se može smanjiti smanjenjem dimenzija debelih slojeva kao i smanjenjem debljine podloge. Sa druge strane, potrebno je u primeni koristiti NTC paste sa različitom veličinom NTC parametra B, tj. temperaturne zavisnosti otpornosti termistora od temperature, od linearnih do brzorastućih eksponencijalnih. Da bi se ovakvi specifični zahtevi za materijalima i prilagođenim konstrukcijama realizovali, potrebno je dublje poznavanje (Mn, Ni, Co, Fe, Cu)3O4 kompleksnog spinela i faznog dijagrama nastanka ovog materijala. Pored toga, neophodno je stalno merenje i kontrola parametara sinterovanja i njihovo povezivanje sa elektronskim svojstvima dobijenog materijala. Kod debelih slojeva koji imaju elektrode na bazi PdAg ili drugih metala koji se koriste kao elektrode potrebno je pratiti proces difuzije tog metala kroz površinu termistorskog debelog sloja na koju se elektroda nanosi. Na kraju, radi primene novodobijenih namenskih termistorskih debeloslojnih naprava, potrebno je izvršiti električna i klimomehanička merenja dobijenih senzora.
Izrada debeloslojnih senzora zahteva kompletan multidisciplinarni pristup, počev od fizičke hemije, fizičke elektronike materijala, posebno sinterovanja, do merenja termičkih i električnih svojstava i njihove primene u elektronici. 
U ovoj tezi upravo je prikazan kompletan ciklus istraživanja, sinteza i karakterizacija praha, formiranje paste, optimizacija uslova sinterovanja (vreme i temperatura) koja je vršena u svrhu primene termistorskog materijala za merač protoka vazduha. Na bazi segmentiranog termistora koji osim glavnih ima interne elektrode i koji je u osnovi višećelijska konstrukcija, realizovan je poseban namenski tip senzora za merenje temperature i protoka vazduha. Analizirana je brzina odziva za dva tipa senzora sa indirektnim i sopstvenim zagrevanjem i date su krive baždarenja odnosno promene električnih svojstava, kao što su napon i struja kroz termistor u odnosu na kvazistatičke i brze promene protoka. 
Teza je podeljena u pet osnovnih delova. Posle uvoda, dat je teorijski deo. U njemu su data osnovna  toplotna i električna svojstva NTC termistora kao što su mehanizam provođenja, zavisnost otpornosti od temperature, vreme odziva termistora, toplotna svojstva, starenje termistora i dr. Odmah zatim, data je  građa NTC termistora i fazni dijagrami nastanka (Mn, Ni, Co, Fe, Cu)3O4 kompleksnog spinela. Sinterovanje NTC termistora obuhvatilo je profile sinterovanja, kao i uticaj dopanata na otpornosti. Tehnika izrade debelih slojeva prikazana je kroz sledeće postupke i procese: pravljenje paste i podloge u tehnici debelih slojeva, štampanje i sušenje paste, potom sinterovanje debelih slojeva i njihova mikrostuktura. Primena NTC termistora data je u merenju temperature, merenju protoka, vlage, zatim u kolima za kašnjenje, kao i u zaštiti u elektronici. 
U eksperimentalnom delu, dat je prikaz sinteze NTC praha koja uključuje mešanje oksida, kalcinaciju, mlevenje i na kraju presovanje i sinterovanje. Karakterizacija termistorskog praha na  dobijenim isprescima izvršena je raznim fizičko hemijskim metodama (skanirajućom elektronskom mikroskopijom (SEM), elektronskom disperzionom spektroskopijom (EDS), dalekom infracrvenom spektroskopijom (FTIR), fotoakustičnom metodom (PA) i rendgenostrukturnom analizom.
Posebno su opisani segmentirani debeloslojni NTC termistori, njihova građa, i UI karakteristika. Kao prikaz potpune aplikacije ovih senzora, realizovan je namenski napravljen senzor protoka vazduha sa segmentiranim NTC termistorom, u kome je data metoda sa indirektnim zagrevanjem, metoda sa sopstvenim zagrevanjem konstantnim strujama, merenje temperature ovim senzorom i merenje vremenskog odziva sistema.
U diskusiji dobijenih rezultata data su objašnjenja svih metoda koje su korišćene u karakterizaciji samog materijala, zatim je data analiza radnih tačaka i radnog režima segmentiranog NTC termistora i uporedna analiza metoda za merenje protoka kao i uporedna analiza inercije sistema obe gore navedene metode. Na kraju je dat zaključak i korišćena literatura.

AB  - An investigation path starting from (Mn,Ni,Co,Fe)3O4 nanometric powder preparation, NTC thick-film characterization, realization and optimization of new planar thermistor geometries to custom design thermistors and their application for temperature and volume airflow sensors was recently determined. The aim was to make custom designed segmented NTC thermistors printed and sintered on alumina. Two types of volume airflow sensors were formed: indirectly heated and self-heated. A pair of segmented thermistors was placed in an air guide and connected to differential branches of the Wheatstone bridge. A heater was placed in the middle between the thermistors for the indirectly heated type, while for the self-heated type the same thermistors were self-heated by a constant current source. First the thermistor responses vs. the airflow (calibration curves) were measured, and then thermistor responses in time (inertia) to fast airflow changes from the minimum to the maximum. The results obtained could be applied in air conditioning for air guide flow regulation.

A heater was placed in the middle between the thermistors for the indirectly heated type, while for the self-heated type the same thermistors were self-heated by a constant current source. First the thermistor responses vs. the airflow (calibration curves) were measured, and then thermistor responses in time (inertia) to fast airflow changes from the minimum to the maximum. The results obtained could be applied in air conditioning for air guide flow regulation.",

AB  - A high purity single crystal Ge with a (1 1 1) orientation was doped with Cr. A thin film of Cr was evaporated and then diffused into Ge substrate. The photoacoustic PA amplitude and phase spectra were measured and numerically analyzed. The substitution of Cr in Ge produces a compensation effect.
