Flexible piezoelectric PZT/fabric composite material is pliable and tough in nature which is in a lack of traditional PZT patches. It has great application prospect in improving the sensitivity of sensor/actuator made by piezoelectric materials especially when they are used for curved surfaces or complicated conditions. In this paper, glass fiber cloth was adopted as carrier to grow PZT piezoel...

The origin of phosphorus metabolism is one of the central problems in the context of the emergence of life on Earth. It has been shown that the C–H–O system can be transformed into a fourcomponent C–H–O–P system with the formation of a gluconeogenesis path in a possible Archean hydrothermal condition under the influence of a phosphorus chemical potential. This system became the energy supply ba...

This paper deals with the optimization of a hydrothermal problem that considers a non-smooth Lagrangian L(t, z, z′). We consider a general case where the functions Lz′ (t, ·, ·) and Lz(t, ·, ·) are discontinuous in {(t, z, z′)/z′ = φ(t, z)}, which is the borderline point between two power generation zones. This situation arises in problems of optimization of hydrothermal systems where the therm...

The influence of reaction conditions on the composition of liquid products during two-stage hydrothermal conversion of alkali lignin has been investigated in a batch reactor. Reactions were carried out in the presence of formic acid (FA) and Pt/Al2O3 catalyst. The two different sets of reaction conditions involved alternative reaction times of 1h and 5h at 265°C and 350°C, respectively. These p...

the nasirabad manganese deposit is located 5 km south of nasirabad, 8 km sw of neyriz in the fars province. structurally, the area is placed in the southeastern part of zagros thrust belt. in this area, the manganese mineralization occurred as ore layers and nodules, interlayered with pichakun radiolarite chert deposits. in this study, mineralogy and geochemistry of uranium, thorium and lead is...

in a hydrothermal route devoted for synthesis of ca10(po4)6(oh)2 (ha) nanostructures, morphology can be controlled by experimental condition to form magical ha or nanostructured nanoparticles. in an intermediate condition, a novel nanostructure namely rose-like bundle of ha rod-likes was found, which is different from known ha nanostructures. the chemical synthesis of nanopowders under hydrothe...

geopolymer cement (inorganic polymeric binder) based on natural pozzolan are investigated. SiOof activator and total molar ratios of Nacomposition exhibiting the highest 28-day compressive strength. Mixtures exhibiting the highest compressive strength were studied for their molecular structure using laboratory technique of Fourier transform infrared spectroscopy.Results obtained confirm that ch...

Hydroxyapatite nanorods aligned with ultrahigh crystallinity and high-yield were successfully synthesized through a hydrothermal approach. In this experiment, a new composition of cetyltrimethylammonium bromide ((CH3(CH2)15N+(CH3)3Br-) was designated as CTAP)/Ca(NO3)2/(NH4)2HPO4/NaOH and distilled water under hydrothermal condition, to synthesize single crystalHAp nanorods with diameter of 20 ±...
