AI, NANOTECHNOLOGY
What is Nanotechnology? : includes the manipulation of materials with dimensions less than 100 nanometers ( it is one billionth of a meter) where the physical and chemical properties can differ significantly from those on a larger scale. From Richard Feynman's pioneering ideas in 1959, to modern applications, nanotechnology has come a long way; Materials can exhibit unique electrical conductivity, mechanical strength, and chemical reactivity.
It is a fascinating and rapidly growing field that focuses on the manipulation and control of matter at the nanoscale, i.e. at the level of atoms and molecules. This interdisciplinary field combines principles of physics, chemistry, biology and engineering to develop new technologies and materials with unique properties.
A world where doctors can deliver treatments directly to diseased cells, iron oxide nanoparticles are being used in hyperthermia treatments for cancer, where the particles are heated to destroy cancer cells without damaging surrounding tissue; where electronic devices are so small that they become invisible to the naked eye, and where materials are stronger and lighter than ever. This is not a science fiction scenario, but the reality that nanotechnology is beginning to make possible.
xxx It is transforming various sectors with its innovations, from medicine to energy. Methods such as lithography, chemical vapor deposition and self-assembly are used to manufacture and manipulate nanomaterials.
Applications:
Medicine : Nanomedicine, drug delivery, imaging and diagnostics; Nanoparticles designed to release drugs in a controlled manner are revolutionizing cancer treatment.
Electronics : transistors, memory and flexible devices.
Carbon nanotube transistors are taking electronics to new heights in terms of speed and efficiency. The IBM company has developed carbon nanotube transistors that are up to ten times more efficient than traditional silicon transistors.
Energy : Solar panels with energy storage and energy efficiency are improving their efficiency and that of batteries, making renewable energy more viable.
"MIT researchers have created solar panels using quantum dots that have increased energy conversion efficiency by 50%."
