|Have you ever wondered why many of the things we use every day are getting smaller? This is occurring because, we can now create and manipulate objects that are on the order of 1 billionth of a meter. In nature many important processes occur on scales much smaller than the size of a single living cell. Objects this small are such that tens of trillions of them would fit inside a single, tiny, rain droplet. For example: Oxytocin the neuropeptide molecule that makes it possible for mothers to love their babies, is this small. The size of the tiniest virus is only a few nanometers in length; the antireflection coating on the lenses of most glasses is about 100 nanometers thick, while the size of the smallest printer droplet and the smallest airborne allergen are approximately 1000 nanometers. These are just some of the many things that exist in the nanoworld!The method and science behind the manipulation of objects on this scale is called nanoscience. Scientists in this new and emerging field seek to comprehend, gather and organize knowledge of the nanoworld through careful observations and creative, visionary thinking. Nanoscience is a multidisciplinary field bringing together vast knowledge from mathematics and all the core sciences: physics, biology, chemistry, and from their derivatives such as material science, pharmacology, neurochemistry, ecology etc. Consequently, nanoscientists are scientists engaging in an organized activity of manipulation of materials at atomic, molecular and macromolecular scales that are versatile and fluent in mathematics and the core sciences with a particular world view based on the synergy of these core sciences and on their derived applications to the macro world.Nanoscience is a new way of thinking about old things. In nanoengineering it’s a “bottom-up” approach rather than our usual “top-down” approach of taking large elements and miniaturizing them. Instead, “bottom-up” thinking offers a way to build complex materials and devices by capitalizing on the functionality of the matter constituents and their assembly in the nanometer regime. At this scale many novel structures and properties emerge that would awe even the most illustrious science fiction writers! As an example, carbon nanotubes, the strongest and stiffest material yet discovered, are many times stronger than any metal and harder than any diamond found in nature! Nanodots offer the possibility of storing an entire library by using billions of tiny magnets on the nanoscale. A nanodot can hold hundreds of times more information that today’s largest hard drives.At JSNN you will join the top scientists working closely on the emerging techniques and technologies derived from nanoscience and doing cutting edge research with the state-of-the-art equipment!
