What is nano

New iPods: Your iPod nano and iPod shuffle are looking aged, so maybe it's time for a hardware update? It may seem like batteries have improved dramatically — consider the lifespan of an iPod Nano versus a portable cassette player.

One tiny—and, in some cases, Nano -size—device would revolutionize how the world listened to music. Nano Amaldi's injuries proved far less serious than was at first believed. He busied himself over his Nano -cakes and nuts, and prevailed on Battle to eat by making him laugh at his antics.

John Nano , who spoke several tongues, said that he did not know it in any Indian dialect except in that of his gypsies. Saying this he handed me a piece of paper, with his name written on it: John Nano.

Matter such as gases, liquids, and solids can exhibit unusual physical, chemical, and biological properties at the nanoscale, differing in important ways from the properties of bulk materials and single atoms or molecules.

Some nanostructured materials are stronger or have different magnetic properties compared to other forms or sizes of the same material. Others are better at conducting heat or electricity. They may become more chemically reactive or reflect light better or change color as their size or structure is altered. Quantum dots: the color of fluorescence is determined by the size of particles and the type of materials. Learn about the beginning of the science of studying the extremely small and its fundamental concepts.

Over a decade later, in his explorations of ultraprecision machining, Professor Norio Taniguchi coined the term nanotechnology. It wasn't until , with the development of the scanning tunneling microscope that could "see" individual atoms, that modern nanotechnology began.

One nanometer is a billionth of a meter, or 10 -9 of a meter. Here are a few illustrative examples:. Nanoscience and nanotechnology involve the ability to see and to control individual atoms and molecules. Everything on Earth is made up of atoms—the food we eat, the clothes we wear, the buildings and houses we live in, and our own bodies.

But something as small as an atom is impossible to see with the naked eye.
