Continuous microwave-assisted flow synthesis has been used as a simple, more efficient, and low-cost route to fabricate range of nanosized (<100 nm) strontium-substituted calcium phosphates. In this study, fine nanopowder was synthesized via continuous with microwave assistance from the solutions nitrate tetrahydrate (with strontium Sr2+ ion source) diammonium hydrogen phosphate at pH 10 tim...
calcium doped nickel ferrite powders have been prepared by sol-gel combustion technique. metal nitrates, such as calcium nitrate, nickel nitrate and ferric nitrate, were used as the source materials and citric acid and polyvinyl alcohol were used as the burning agent and agglomeration reducing agent, respectively. the average crystallite size of the prepared ferrite was in the order of ~70- 92 ...
In this study we have characterized the mode of cell adhesion to calcite and calcium (R,R)-tartrate tetrahydrate crystals. The use of crystals as adhesion substrata was motivated by their well-established chemical nature and structurally defined surfaces. We show that calcite binds A6 Xenopus laevis epithelial cells rapidly and efficiently, most likely via surface-adsorbed proteins. Surface top...
Both calcium and caffeine induced calcium release from actively loaded heavy sarcoplasmic reticulum vesicles were studied to analyze the dependence of both activities on the composition of the release medium with respect to monovalent anions. Calcium is unable to induce net calcium release while caffeine remains effective as releasing agent when the experimental media contain neither chloride n...
In this work, sol-gel processing was used to synthesize the fluorohydroxyapatite (nano-FHA, Ca10(PO4)6(OH)2−xFx) nanopowders. The advantages of the sol-gel method over other methods are precise control of composition, low processing temperature, and better homogeneity. Calcium nitrate tetrahydrate, phosphorous pentoxide and Tetrabuthylammon...
Over the past decades, bioactive glass (BG) has been of a great interest in the bone regeneration field, due to its excellent biocompatibility, bioactivity and osteoconductivity. Herein, fabrication of bioactive glass as one-dimensional fibers by employing an Electrospinning process is reported. The Sol-Gel method was chosen considering the final fibers smoothness and homogeneity. Starting sol ...

Interactions during cell adhesion to external surfaces may reach the level of discrimination of molecular chirality. Cultured epithelial cells interact differently with the [011] faces of the (R,R) and (S,S) calcium tartrate tetrahydrate crystals. In a modified version of the classical Pasteur experiment, the enantiomorphous crystals were sorted out from a 1:1 mixture by the selective adhesion ...
