Hydroxyapatite-brushite mixtures: Synthesis and physicochemical characterization

Study of the effects of heat-treatment of hydroxyapatite synthesized in gelatin matrix

“…At temperature increase up to 400°C, the peak intensity falla, and at temperature up to 600°C, it completely disappears, which is consistent with the data in [17].…”

Interaction of magnetic accumulation nanomaterials and nanocomposites with cells, viruses, bioacactic molecules, ions of hard metals

“…Якщо значення рН менше точки нульового заряду, то переважатимуть на поверхні групи ≡FeOН 2 + (групи ≡FeOв меншості), а по мірі зростання рН кількість груп ≡FeOзбільшується (рис. 10) [164].…”

Rhodium(0) nanoparticles supported on hydroxyapatite nanospheres and further stabilized by dihydrogen phosphate ion: A highly active catalyst in hydrogen generation from the methanolysis of ammonia borane

“…Although the hydrolysis of AB has been extensively studied and widely accepted, the methanolysis of AB has a series of advantages: (i) the solubility of AB in methanol is high, 23% wt. at 23 C [18], (ii) the solution of AB in methanol is highly stable with respect to selfmethanolysis at ambient conditions, (iii) pure hydrogen can be produced from methanolysis of AB without ammonia contamination [19,20], (iv) methanolysis of AB can be initiated at temperatures below 0 C in the presence of appropriate catalyst, which facilitates portable applications in cold weather [21], (v) the methanolysis product of AB, NH 4 B(OCH 3 ) 4 , can be converted back to AB by a room temperature reaction with LiAlH 4 plus NH 4 Cl [19]. Methanolysis can release 3.0 equivalents of H 2 per mole of AB only in the presence of a suitable catalyst (eqn.…”
