Abstract: Zirconia solid electrolytes with nonequilibrium composite structure were prepared by impregnation of a porous 8YSZ matrix with a solution of Zirconia. Microstructures were characterized by XRD and SEM. The electrical properties were studied by impedance spectroscopy as a function of temperature. Biaxial flexural strength and fracture toughness of composite samples were measured by rin...

Non-modulation has been proposed as an intermediate phenotype in human essential hypertension. The trait is characterized by blunted aldosterone and renal plasma flow responses to short-term angiotensin II (Ang II) infusion. Elevated tissue Ang II levels or decreased tissue adenosine levels could account for this decreased sensitivity to Ang II. In support of the latter possibility, endogenous ...

Early differences in hemodynamic variables and vasoactive substances between progeny of hypertensive and normotensive parents were sought in normotensive children aged 10-17 years. Forty-two black and 34 white children of hypertensive parents (cases) and an age-balanced group of 20 black and 45 white children of normotensive parents (controls) underwent exercise stress testing. Blood pressure, ...

A series of thermoplastic polymer electrolytes have been prepared employing poly(ethylene oxide) (PEO) as a polymer matrix, bis(trifluoromethane sulfonimide) (LiTFSI), and different room-temperature ionic liquids (RTIL) with bis(fluorosulfonyl)imide (FSI) or TFSI anions. This formulation makes them safe and non-flammable. The electrolytes have been processed in the absence of solvents by melt c...

Moving away from conventional solid oxide electrolytes, hybrid fuel cells based on composite electrolytes (a solid oxide electrolyte and a molten alkaline carbonate phase) exhibit promising performance due to the high electrolyte conductivity within the so-called intermediate temperature ranges (400-600 C). These electrolytes are a blend of those traditionally used in Solid Oxide and Molten Car...

Electrolyte is a key material for success in the research and development of next-generation rechargeable batteries. Aluminium rechargeable batteries that use aluminium (Al) metals as anode materials are attractive candidates for next-generation batteries, though they have not been developed yet due to the lack of practically useful electrolytes. Here we present, for the first time, non-corrosi...

Background. We have previously discovered connections between the lithogenicity index of urine and a number components its composition. The aim this study is to determine relationship metabolic plasma. Materials Methods. Experiment was performed on 60 healthy old female Wistar rats 220-300 g. Ten animals remained intact, using daily water from drinking ad libitum. Other for 6 days were loaded t...

abstract the whole blood potassium concentration has shown the bimodal distribution in sheep, which has been classified into lk and hk types; hk allele is recessive to lk with a single gene inheritance. this polymorphism showed different behavior in different environment, which could be due to adaptation process. this research was conducted on the zel and kermani breed research station, which k...

A childless 24-year-old housewife was admitted to hospital in May 1969. At Easter she had begun to develop generalized muscular pains and feelings of faintness. She then became increasingly depressed and subject to outbursts of tears, complained of lethargy, anorexia, and bouts of nausea and vomiting, and more recently had developed polyuria, thirst, and nocturia and a liking for salty food. Sh...

Solid polymer electrolytes, such as polyethylene oxide (PEO) based systems, have the potential to replace liquid electrolytes in secondary lithium batteries with flexible, safe, and mechanically robust designs. Previously reported PEO nanocomposite electrolytes routinely use metal oxide nanoparticles that are often 5-10 nm in diameter or larger. The mechanism of those oxide particle-based polym...
