Nanotubes go with the flow to penetrate brain tissue
Engineers develop microfluidic devices, microelectrodes for gentle implantation.
Researchers show thermally activated delayed photoluminescence from semiconductor nanocrystals
Researchers have found that the transfer of triplet excitons from nanomaterials to molecules also creates a feedback mechanism that returns some energy to the nanocrystal, causing it to photoluminesce on long time scales. The mechanism can be adjusted to control the amount of energy transfer, which could be useful in optoelectronic applications.
Particle size matters for porous nano building blocks
Scientists find porous nanoparticles get tougher under pressure, but not when assembled.
Bilirubin-filled nanocapsules could improve survival of transplanted pancreatic cells
By encapsulating bilirubin within tiny nanoparticles, researchers have improved the survival rates of pancreatic islet cells in vitro in a low-oxygen environment. The work has implications for the treatment of Type 1 diabetes in both canine and human patients.
Nanoscale super-resonator extends light lifetime
Scientists designed the first subwavelength dielectric resonators for light trapping at the nanoscale that appears to be the simple silicon cylinder hundred times thinner than a human hair.
Process to transition two-layer graphene into diamond-hard material on impact discovered
The innovation could enable development of a range of flexible, impenetrable materials capable of protecting the body and fragile objects.
Fast flowing heat in layered material heterostructures
Researchers have detected graphene's out-of-plane heat transfer in van der Waals heterostructures. This phenomenon has many implications for optoelectronic devices.
Quantum material has shark-like ability to detect small electrical signals
A 'quantum material' that mimics a shark's ability to detect the minute electric fields of small prey has been shown to perform well in ocean-like conditions, with potential applications from defense to marine biology.
