Nanosilicates grow bone and cartilage tissue from stem cells in the absence of growth factors

Nanowerk.com - 13 апреля, 2018 - 15:56
Researchers have demonstrated that a specific type of two-dimensional (2D) nanoparticles, nanosilicates, can grow bone and cartilage tissue from stem cells in the absence of growth factors. These nanoparticles are similar in shape to a coin, but 10 billion times smaller in size. Nanosilicates consist of minerals such as sodium, silicate, magnesium and lithium, which are already present in the body. This avoids the use of growth factors in the human body, which can generate harmful effects including unwanted tissue growth, such as a tumor.

Mechanism of oxidative unzipping of multiwall carbon nanotubes to graphene nanoribbons

Nanowerk.com - 12 апреля, 2018 - 18:27
Researchers demonstrate that the oxidative unzipping of MWCNTs is intercalation-driven, not oxidative chemical-bond cleavage as was formerly proposed. The unzipping mechanism involves three consecutive steps: intercalation-unzipping, oxidation, and exfoliation.
