Coated Tissue Scaffolds Help the Body Grow New Bone

Chemical engineers from MIT have developed coated tissue scaffolds that help the body grow new bone to repair injuries or congenital defects. MIT chemical engineers have devised a new implantable tissue scaffold coated with bone growth factors that are released slowly over a few weeks. When applied to bone injuries or defects, this coated scaffold […]

New Membrane Can Separate Highly Mixed Oil Spill Residues

A newly developed membrane can separate highly mixed fine oil-spill residues, processing large quantities of the finely mixed materials back into pure oil and water. Whenever there is a major spill of oil into water, the two tend to mix into a suspension of tiny droplets, called an emulsion, that is extremely hard to separate […]
