Advanced Functional Materials, EarlyView.A mechanically tunable hydrogel composed of gelatin, chondroitin sulfate and laminin promotes angiogenesis in vitro without the supplement of growth factors. Endothelial cells morphogenesis was further enhanced by medium conditioned with bioactive glass 58S‐released ions (Ca and Si), thus offering a promising strategy to vascularize 3D tissue ...

Bioceramics: spark plasma sintering (SPS) of calcium phosphates [PDF]
, 2006 Calcium phosphates (Ca-P) are major constituents of calcified tissues, and are also extensively used for the elaboration of biomaterials. However, the usual high-temperature sintering processes generally lead to strong alterations of their chemical ...

Introducing Pure Calcium Orthophosphate Gels and Aerogels
Advanced Functional Materials, EarlyView.The synthesis of calcium phosphate‐based gels and aerogels is reported, which exhibit highly porous structures built up of networks of nanoparticles. In case of amorphous aerogels, this leads to yet unmatched specific BET surface areas, making these materials especially interesting for biomedical applications.

Model Evaluation the Effect of Size, Shape and Surface Condition of Apatite Nanocrystals on the Deviation of Ca / P ratio from stoichiometric [PDF]
Журнал нано- та електронної фізики, 2014 The causes of Са / Р ratio deviation in biological apatites from stoichiometric one were discussed. By the simple model evaluation Са / Р ratio was shown to deviate from stoichiometric one because of small sizes of crystals, and peculiarities in chemical

X-ray diffraction study of cadmium hydroxyapatite [PDF]
, 2005 Solid solutions of cadmium and calcium hydroxyapatite [Ca10−x Cdx (PO4)6 (OH)2 (0 ≤ x ≤ 10)] were synthesized by a wet process in a basic medium. The lattice dimensions of these compounds vary linearly with the atom percent cadmium.

Bio‐Inspired Nanoarchitected LiFePO4 Cathodes
Advanced Functional Materials, EarlyView.Lithium iron phosphate (LFP) is synthesized using a bio‐inspired method, using acidic macromolecules similar to those found in many calcareous mineralized organisms to modulate the morphology and crystal growth of LFP‐carbon composite particles. The observations from this process indicate a non‐classical crystallization process, which subsequently ...
