- General methods of making 1D structures - Synthesis of nanotubes and nanowires by high temperature (CVD) methods: - mechanisms - furnace systems - film growth; effects of basic process parameters - methods for and limitations to structural control - VLS precipitation model
Oxford Nanopore Technologies is developing a new generation of DNA sequencing technology that does not require fluorescent labels or optical instrumentation, identifying the series of bases directly using electronics. This animation shows the BASE sequencing process. For further information visit www.nanoporetech.com.
I this lecture, Prof. S. Ravi P. Silva will explore the issues pertaining to the Energy Challenge posed by the human- race. How could Nanotechnology provide a glimmer of hope for revolutionising Green Energy solutions? Nanotechnology holds one of the keys to help stop the catastrophic change taking place to our global climate. The most important ingredient to make use of nanotechnologies for green energy solutions is a mind prepared to experiment and implement radical revolutionary ideas with modern know-how.
Nanocrystals are small collections of several hundred to hundred thousand atoms arranged in a crystal matrix. Quantum dots are nanocrystals made of semiconductors, and the several hundred atoms act like one giant molecule with regards to their electrons with variations in energy levels due to the size of the dot. The smaller the dot, the higher photon energy released during fluorescence.
This video was compiled from fluorescing colloidal quantum dots of different sizes excited by an argon laser. The dots are invisible (with one exception in a microscope at 2:14) but they produce the bright colors in the beam. The bits of bright blue flashes are dust particles in the solutions.
