EFFECT OF ANNEALING ON GAS SENSING PERFORMANCE OF NANOSTRUCTURED ZnO THICK FILM RESISTORS

ZnO nano-particles have been synthesized by simple chemical route using a starting solution consisting of zinc acetate and citric acid as a surfactant agent. The structural properties of the prepared ZnO nano-particles annealed at different temperatures have been characterized by X-ray diffraction (XRD) and transmission electron microscopy (TEM) analyses. The XRD patterns show ZnO-wurtize phase in the nano-powders, and size of crystals increases by increasing the annealing temperatures. The TEM

AN EXTENSIVE STUDY, DESIGN AND SIMULATION OF MEMS GUIDED MEDIA: MICROSTRIP LINE

velocity, and attenuation constant of the dominant mode of microstrip depend on geometrical factors, on the electronic properties of substrate and conductors used, and on the frequency. Since this is a “mixed” dielectric system, the TEM mode can not be supported [2] and the second portion of the investigation was devoted to the effect of variation of length and frequency on the RF performance of the line. Although many papers are available on this topic, but the issues described in this paper have

NANOSTRUCTURED ZnCo2O4THICK FILM AS AN ETHANOL SENSOR

Semiconductive nanometer-size material ZnCo2O4 was synthesized by a solution combustion reaction of inorganic reagents of Zn(NO3)3. 6H2O, Co(NO3)3.6H2O and glycine as a fuel. The process was a convenient, environment friendly, inexpensive and efficient preparation method for the ZnCo2O4 nanomaterial. The synthesized materials were characterized by TG/DTA, XRD, EDX, SEM, and TEM. Conductance responses of the nanocrystalline ZnCo2O4 thick film were measured by exposing the film to reducing gases

New Look on Antifungal Activity of Silver Nanoparticles (AgNPs)

concerning growth inhibition of other bacteria (Enterococcus spp.) and yeast (Candida albicans) by nanosilver is also available (Kim et al. 2007; Roe et al. 2008; Lara et al. 2015). However, the studies of AgNPs interaction with cell structures of bacteria and yeasts are scarce. Only in few reports the location of AgNPs inside C. albicans cells was demonstrated under transmission electron microscopy (TEM) or scanning electron microscopy (SEM) (Kim et al. 2009; Radhakrishnan et al. 2018). In opposite to

SYNTHESIS OF NANOSTRUCTURED ZrO2 FOR GAS SENSING APPLICATION

Nanocrystalline ZrO2 (Zirconia) has been synthesized by a conventional precipitation method. The structural, morphological, microstructural, optical and gas-sensing properties of ZrO2 were investigated by using X-ray diffraction analysis (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), UV-vis spectroscopy and static gas sensing unit, respectively. X-ray diffraction pattern and TEM of the synthesized product reveal their nano-crystalline nature with grain size

Humidity sensor based on silver nanoparticles embedded in a polymeric coating

In this work, it is presented a novel optical fiber humidity sensor based on silver nanoparticle-loaded polymeric coatings built onto an optical fiber core. The polymeric film was fabricated using the Layer-by-Layer assembly technique. The silver nanoparticles (Ag NPs) were characterized using transmission electron microscopy (TEM and UV-VIS spectroscopy. A Localized Surface Plasmon Resonance (LSPR) attenuation band is observed when the thickness of the coating increases, and showed a very good

SYNTHESIS, CHARACTERIZATION AND GAS SENSING PERFORMANCE OF SOL-GEL PREPARED NANOCRYSTALLINE SnO2 THIN FILMS

Nanocrystalline SnO2 thin films were successfully prepared using sol-gel dip coating technique. The starting precursor was used as tin chloride dihydrate (SnCl2.2H2O), ethanol and glycerin. As the prepared films were fired at 500oC. These films were characterized using XRD, FESEM and TEM to known crystal structure, surface morphology and microstructure property. Elemental composition was studied using energy dispersive spectrophotometer (EDAX). The H2 gas sensing performance of nanocrystalline

EFFECT OF CeO2 DOPING ON THE STRUCTURE, ELECTRICAL CONDUCTIVITY AND ETHANOL GAS SENSING PROPERTIES OF NANOCRYSTALLINE ZnO SENSORS

Nanocrystalline sensors having the general formula ZnO + x wt% CeO2, where x = 0, 2, 4 and 6 were prepared by chemical precipitation method and sintered at 400, 600 and 800 oC for 2h in static air atmosphere. The crystal structure and the morphology of the prepared samples were investigated and characterized by using XRD, IR, SEM and TEM techniques. The investigation revealed that the average crystallites size increases with increasing the sintering temperature. The electrical conductivity is

Effects of PINK1 mutation on synapses and behavior in the brain of Drosophila melanogaster

Bruchpilot (BRP), a presynaptic scaffolding protein that is crucial for neurotransmission in all type of synapses in Drosophila. In addition, other proteins that are involved in synaptic transmission; Rab5, Syntaxin and Wishful Thinking were also decreased in abundance in mutants, except Synaptotagmin. Transmission electron microscopy (TEM) also confirmed less and abnormal synaptic vesicles at tetrad synapses in the visual system of PINK1 mutants. The lower level of BRP and longer day sleep observed was
