Sugar-Coated Nanomaterial Excels at Promoting Bone Growth

There hasn’t been a gold standard for how orthopaedic spine surgeons promote new bone growth in patients, but now Northwestern University scientists have designed a bioactive nanomaterial that is so good at stimulating bone regeneration it could become the method surgeons prefer.

Graphene Encapsulation Provides Unprecedented View of the Diffusion and Rotation of Fullerene Molecules

Meyer_illustration1.jpg

Scientists at the University of Vienna have created a new hybrid structure, termed buckyball sandwich, by encapsulating a single layer of fullerene molecules between two graphene sheets. Buckyball sandwiches combine for the first time soccerball-like fullerenes, each consisting of sixty carbon atoms, and graphene, a one-atom thick layer of carbon. This structure allows the scientist to study the dynamics of the trapped molecules down to atomic resolution using scanning transmission electron microscopy. They report observing diffusion of individual molecules confined in the two-dimensional space, find evidence for the rotation of isolated fullerenes within the structure, and even follow their merging into larger molecular clusters.

Lab on a Chip Could Monitor Health, Germs and Pollutants

LabChip2RUTodayimage_highresolution.jpg

Imagine wearing a device that continuously analyzes your sweat or blood for different types of biomarkers, such as proteins that show you may have breast cancer or lung cancer. Rutgers engineers have invented biosensor technology – known as a lab on a chip – that could be used in hand-held or wearable devices to monitor your health and exposure to dangerous bacteria, viruses and pollutants.

Heterogeneous nanostructured materials are widely used in various optoelectronic devices, including solar cells. However, the nano-interfaces contain structural defects that can affect performance. Calculations run at NERSC helped researchers ID the root cause of the defects in two materials and provide design rules to avoid them.
