Plant inspiration could lead to flexible electronics

Versatile, light-weight materials that are both strong and resilient are crucial for the development of flexible electronics, such as bendable tablets and wearable sensors. Aerogels are good candidates for such applications, but until now, it’s been difficult to make them with both properties. Now, researchers report that mimicking the structure of the ‘powdery alligator-flag’ plant has enabled them to make a graphene-based aerogel that meets these needs.

Enhanced photocatalytic activity by Cu2O nanoparticles integrated H2Ti3O7 nanotubes

Compositing Cu2O nanoparticles with H2Ti3O7 nanotubes provides an effective strategy to reduce the bandgap energy and the recombination of photo-generated electrons and holes. There is an obvious synergistic effect between guest nanoparticles and host nanotubes due to the interaction to form heterojunction struction, which will enhance photocatalytic oxidation performance for removal of EM due to the stronger visible spectral response and wider absorbance in the long visble light region.

Nanoparticle based contrast agent developed for dual modal imaging of cancer

Dual modal imaging which shares the advantages of two imaging modalities such as magnetic resonance imaging and optical imaging, has the ability to produce images with higher spatial resolution and higher sensitivity. Contrast agents having both magnetic and optical properties identifies the cancer cells efficiently. Europium doped gadolinium oxide nanorods were synthesized and subsequently coated with silica to improve the biocompatibility.

Graphene encapsulation provides unprecedented view of diffusion and rotation of fullerene molecule

Scientists have created a new structure by encapsulating a single layer of fullerene molecules between two graphene sheets. Buckyball sandwiches combine fullerenes and graphene. This structure allows 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 and even find evidence for the rotation of isolated fullerenes within the structure.
