Graphene-oxide-based membranes for large-scale energy storage systems

Tue, 04/17/2018 - 10:43
As a promising large-scale energy storage technology, redox flow batteries (RFBs) are attracting increasingly more research attention. For RFB separators, the essential requirement is achieving high ionic conductivity with minimal cross-over at low cost. Researchers now have demonstrated a proof-of-concept graphene oxide (GO) membrane as separator for large-scale energy RFBs. Their work shows that the two-dimensional nanochannel structure and low frictional water flow inside micrometer-thick GO laminates make this material an attractive candidate membrane for large-scale energy storage systems.

Researchers create a new Bose-Einstein condensate

Tue, 04/17/2018 - 10:37
Unlike most previous Bose?Einstein condensates created experimentally, the new condensate does not need to be cooled down to temperatures near absolute zero. Because the particles are mostly light, the condensation could be induced in room temperature.

Driving nanomotors through road blocks inside living cells

Mon, 04/16/2018 - 13:03
Researchers demonstrate that helical shaped magnetic nanomotors can be maneuvered inside a living cell. This new and versatile technique has the potential ability to position any payload at any desired location inside a living cell itself, which is of great importance in the field of biology and biophysics. The helical shaped nanomotors are made of mainly silica and a thin layer of magnetic material, while their size is at least ten times smaller than the cell which they enter in. A rotating magnetic field is used to drive the motors inside the cytoplasm with precise control.

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

Fri, 04/13/2018 - 16:56
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.
