Non-classical growth of crystals: Drip by drip

ScienceDaily.com: Nanotechnology News - Wed, 06/21/2017 - 18:32
How do crystals grow? The answer given in current textbooks is: Layer by layer atoms or molecules settle on an existing crystal surface. Chemists have now observed a preliminary stage of this crystal growth in glutamic acid that contradicts this classical principal of growth. Not individual atoms settle on an existing crystal surface, but nano-drips that already contain building blocks for growth.

Plant inspiration could lead to flexible electronics

ScienceDaily.com: Nanotechnology News - Wed, 06/21/2017 - 16:27
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.

Dendrimer nanomedicine - developing efficient therapeutic strategies for the treatment of neurological disorders

NanoWerk.com - Wed, 06/21/2017 - 12:20
Dendrimers have emerged as a powerful class of nanomaterials in nanomedicine due to their unique structural features: globular, well-defined, highly branched and controllable nanostructures where the presence of several terminal groups can be functionalized with different ligands simulating the multivalency present in different biological systems. A recent review article identifies the currently existing dendritic systems and discusses their strengths and caveats in the context of attaining efficient therapeutic strategies for the treatment of neurological disorders.

Enhanced photocatalytic activity by Cu2O nanoparticles integrated H2Ti3O7 nanotubes

ScienceDaily.com: Nanotechnology News - Tue, 06/20/2017 - 17:31
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.
