Fires or toxic gas leakages may have grave consequences like significant pecuniary loss even lead to human victims. In this paper we present an autonomous wireless sensor system for early fire and leak detection. The consists of two modules: a module power management module. operation the is based on pyrolysis product detection which makes it possible detect before inflammation. addition, board can identify type leaking gas. A generic energy scavenging module, able handle both alternating...
In this study, oxide materials La1−xCaxScO3−α (x = 0.03, 0.05 and 0.10) were synthesized by the citric-nitrate combustion method. Single-phase solid solutions obtained in case of calcium content x 0.03 0.05, whereas a calcium-enriched impurity phase was found at 0.10. Water uptake release studied means thermogravimetric analysis, thermodesorption spectroscopy dilatometry. It shown that lower main leads to decrease water uptake. Conductivity measured four-probe direct current (DC) two-probe...
Environmental problems associated with water pollution caused by organic dyes have raised serious concerns. In this context, photocatalytic processes proven to be promising and environmentally friendly methods for purification utilising abundant solar energy. study, a SrTiO
The influence of He ion implantation on the interaction La1-xSrxScO3-x/2 with air has been studied. Features effect state surface irradiated materials are revealed. temperature dependences yield carbon dioxide and water from samples unirradiated ions were obtained. It is shown that into LaScO3 La0.9Sr0.1ScO2.95 subsequent heating in to 1150°C leads a decrease activity these respect CO2 practically does not prevent dissociative dissolution materials.
The effect of irradiation with heavy ions Ne, Ar, and Kr various energies on the structure properties ceramic barium cerate doped neodymium annealed in air at 650°C for 7 hours is studied. It noted that blistering was observed surface during its by low energy Ne ions, whereas it not under low-energy Ar irradiation. Irradiation high caused partial amorphization irradiated material, while non-irradiated did change. In addition, endured solid-phase structural changes. Thus, upon high-energy...
The effects of irradiation with electrons, ions noble gases (Ne, Ar, Kr) and oxygen on the structure properties neodymium-doped barium cerate have been studied using methods X-ray diffraction analysis, scanning electron atomic force microscopy, thermal desorption spectroscopy. It was shown that by low-energy stimulates blistering processes sample surface, while high-energy contribute to formation structures irradiated surface resemble various stages spherulitegrowth. similar were not...
The influence of high-energy oxygen and argon ions irradiation on the structure conductive properties YSZ various composition has been studied. It was shown that with causes minor failures in near-surface regions complex oxide, but does not cause any change type crystal lattice. Apparently, latter is due to fact both defects implanted are mainly located quite deep from surface YSZ. Along this, high radiation resistance layers concentration Y 2 O 3 10 15 mol. %, apparently vacancies initial...
The results of the investigations are presented on effect irradiation with electrons, ions inert gases (Ne, Ar, Kr) and oxygen structure properties Nd-doped barium cerate by methods X-ray diffraction analysis, scanning electron atomic force microscopy, thermal desorption spectroscopy. It is shown that low-energy Ne Ar stimulates blistering processes surface, whereas high energy ion Ne, Kr surface undergoes following stages spherulite growth - nucleation, (view cauliflower), formation...
Abstract. The direct conversion of hydrogen chemical energy into electrical is carried out in fuel cells (FC), which consist an ion-conducting electrolyte and electrodes. Solid oxide proton conductors with a perovskite structure are the perspective materials for use as electrolytes cells. However, efficiency based on them not high enough, leading to cost generated electricity. Therefore, task choosing most effective material urgent. Comparative studies properties barium cerate lanthanum...
