The art of stabilizing entangled spaghetti-like materials

Gene therapy can only be effective if delivered by a stable complex molecule. Now, scientists have determined the conditions that would stabilise complex molecular structures that are subject to inherent attractions and repulsions triggered by electric charges at the surfaces of the molecules.

Bright future for gallium nitride nanowires

The gallium nitride nanowires grown by scientists in the Physical Measurement Laboratory at NIST may only be a few tenths of a micrometer in diameter, but they promise a very wide range of applications, from new light-emitting diodes and diode lasers to ultra-small resonators, chemical sensors, and highly sensitive atomic probe tips.

Better thermal management promises cheaper, greener, cooler electronics

Efforts in the 'Nano packaging technology for interconnect and heat dissipation' (Nanopack) project have resulted in new 'Thermal interface materials' (TIMs) developed with micro- and nanotechnology to greatly increase heat transfer away from chips and other electronic components, in turn reducing the demands placed on cooling systems, lowering costs and reducing energy consumption.

Fighting Parkinson's with carbon nanoparticles

One of the problems affecting the human nervous system is dopamine deficiency. But testing of dopamine concentration is costly and requires sophisticated equipment not available in a doctor's office. Enter a team of Polish scientists who developed a method enabling the detection of dopamine in solutions both easily and cheaply, even in the presence of interferences.

When will nanotechnology's artificial molecular machines start working for us?

Northwestern University chemists recently teamed up with a University of Maine physicist to explore the question, "Can artificial molecular machines deliver on their promise?" Their provocative analysis provides a roadmap outlining future challenges that must be met before full realization of the extraordinary promise of synthetic molecular machines can be achieved.
