Commonly used implants for therapeutic approaches of non-systemically impaired bone do not sufficiently support the healing process of osteoporotic bone. Since strontium (II) has been proven as an effective anti-osteoporotic drug new types of strontium enriched calcium phosphate bone cements were developed. As osteoporosis is characterized by an imbalance of osteoblast and osteoclast activity t...

Thin films of ferroelectric strontium-doped lead zirconate titanate [PSZT, (Pb(0.92)Sr(0.08))(Zr(0.65)Ti(0.35))O(3)] deposited by RF magnetron sputtering have been analyzed by in situ analysis techniques. The in situ techniques employed for this study include micro-Raman spectroscopy and X-ray diffraction (XRD), and variations in thin film structure and orientations for temperatures up to 350 d...

Ionic transport dynamics underpins the functionality of most energy storage and conversion technologies. Yttrium-doped barium zirconate (Y-BZO) has attracted attention as a promising electrolyte for proton-conducting solid oxide fuel cells (PC-SOFCs), which stems from its high proton conductivity and excellent chemical stability at intermediate temperatures (400-700°C) [1]. The Grotthuss mechan...

Characteristics of strontium Strontium was discovered in 1790 in a mine close to the Scottish village Strontian and was isolated in 1808. Strontium is one of the alkaline earth metals and is never found in its free form in nature because it easily oxidises, forming strontium oxide. Strontium, along with calcium and magnesium belongs to group 2 of the periodic table which are divalent cations, w...

To minimize alteration of the La0.6Sr0.4Co0.2Fe0.8O3−δ (LSCF)/Gd0.2Ce0.8O2−δ(CGO20)/Y0.06Zr0.94O2−δ(3YSZ) interface via strontium zirconate formation in solid oxide cells, electron beam physical vapor deposition was employed to manufacture dense, thin gadolinium-doped ceria (CGO) interlayers. CGO layers with thicknesses 0.15, 0.3, and 0.5 μm were integrated state-of-the-art 5 × cm2-large electr...

Antiferroelectric lead zirconate is the key ingredient in modern ferroelectric and piezoelectric functional solid solutions. By itself it offers opportunities in new-type non-volatile memory and energy storage applications. A highly useful and scientifically puzzling feature of this material is the competition between the ferro- and antiferroelectric phases due to their energetic proximity, whi...

Solid oxide fuel cells (SOFCs) have the potential to revolutionise the present fuel economy due to their higher fuel conversion efficiency compared with standard heat engines and the possibility of utilizing the heat produced in a combined heat and power system. One of the reasons they have yet to fulfil this potential is that the conventional anode material of choice, a nickel/yttria-stabilise...

The transfer, from soil to Chinese cabbage and spinach, of radioactive strontium-90 released as a result of accidents in nuclear power stations was studied using a stable isotope of strontium, namely nuclide strontium-88 (88Sr). The study led to an experimental model for assessing the hazard of radionuclide strontium-90 (90Sr) entering the food chain and for predicting the risk to food safety. ...

INTRODUCTION: Strontium plays important role in stimulating the growth of osteoblasts and enhancing the formation of new bone. Therefore, a strontium related compound strontium ranelate (SR) has recently been suggested for use as a daily supplement to treat osteoporosis. However, the true effect of strontium to the stability of hydroxyapatite (HAp) has not been well understood yet, such as why ...
