Porous Strontium Chloride Scaffolded by Graphene Networks as Ammonia Carriers

Ammonia solution strengthened three-dimensional macro-porous graphene aerogel.

Recently, many approaches were applied for assembling graphene sheets into a three-dimensional structure. However, it is still a great challenge to obtain a three-dimensional macroporous graphene network with high mechanical strength after drying. Herein, an ammonia strengthened three-dimensional graphene aerogel was prepared. Based on graphene chemistry and ice physics, the mechanical strength...

Porous Strontium-Containing Ceramic Granules as Bone Graft Substitutes

We have synthesized calcium phosphate-based, strontium (Sr) containing, porous ceramic granules for use as bone graft substitutes. The granules with a particle size between 1 and 2 mm and a (macro)-pore size around 200–500μm were mixed with a fibrin sealant to form a moldable composite material. The starting material with Sr contents between 0 and 100% Sr were precipitated from Ca/Sr solutions ...
