About
The Nanoscience & Nanotechnology Gateway will include important subjects including applied nanoscience, machine learning & AI, applied nanomedicine, nanosafety, and safe- and sustainable-by-design techniques. Over the past few decades, the applications of nanoscience and nanotechnology have developed quickly, and they still hold immense promise for society. Successful application of nanotechnology paves the way for advancements in fuel cells, vaccines, batteries, and building materials.
Nanoscience
The study of materials with extremely small dimensions, on the nanoscale, is at the heart of the developing scientific field known as nanoscience. The word nano is a mix of "science," which means knowledge, plus the word "dwarf," from the Greek "Nanos" (or Latin "nanus"). Nanoscience is the study of materials and processes at the nanoscale through the integration of science, engineering, and technology. The nanometer, which is one billionth of a metre in length, serves as the foundation for the nanoscale. The study of materials with unique properties on an incredibly small scale is the focus of the young scientific field of nanoscience. Nanoscience is the study of ultra-small-scale structures and materials, as well as the distinctive and fascinating characteristics these materials exhibit. To order to better comprehend our world, scientists from a variety of disciplines, including chemistry, physics, biology, medicine, computing, materials science, and engineering, are investigating and applying nanoscience and nanomedicine.
The fact that objects react differently when scaled down to the nanoscale is one of the most fascinating aspects of living in the nanoworld. Fundamentally, changes occur in the physical and chemical properties of matter. Take a look at a piece of yellow gold. The colour of the gold would vary depending on the size of the chunks if you were to divide that lump into nanosized pieces.
It is an interdisciplinary field that focuses on the nanoscale interaction of disciplines like physics, biology, engineering, chemistry, computer science, and more in order to develop mature nanotechnology. The study of phenomena at the nanoscale is known as nanoscience. The average size of a molecule is a few nanometers, and the diameter of an atom is a few tenths of a nanometer. The length scale's magical nanometer represents the boundary between the tiniest artificial objects and atoms and molecules found in the natural world. Nano typically refers to 10-9. A nanometer, which is one billionth of a metre, is the length measurement that is most frequently used to describe the size of a single molecule. Objects smaller than a nanometer cannot be seen with the human eye.
Nanoscience in Physics
The mother of the natural sciences is physics. In principle, everything that occurs at the nanoscale may be explained by physics. Nanomechanics, quantum computation, quantum teleportation, artificial atoms, etc. are all active areas of physics research. Physic at the nanoscale scale is different. The importance of formerly unimportant features, such as thermodynamic and quantum mechanical ones, has increased. One deals with specific atoms and molecules as opposed to bulk materials. Knowing the qualities of each individual molecule allows us to combine them in extremely specific ways to create new materials with novel and remarkable features.
Nanotechnology
Numerous scientific and industrial fields have been touched by the wide range of nanotechnology applications. There are already more than 600 consumer goods based on nanotechnology available, ranging from improved sunscreens and stronger, lighter sports equipment to antimicrobial and stain-resistant fabrics. Processors and batteries for computers and electronics have become smaller and smaller thanks to nanotechnology. Nanomedicine is one of the most exciting applications of nanotechnology, both now and in the future.
Nanotechnology has the ability to completely alter how healthcare is provided to people and how medicine is carried out. Enhanced medical imaging, methods for locating clogged arteries and spotting Alzheimer's disease in its early stages, targeted cancer treatments, and the development of artificial tissues to restore sick organs and nerves are all examples of nanomedicine applications currently in use.
Uses of Nanotechnology
The following are some possible sectors where nanotechnology could be used:
All branches of research, including chemistry, geology, biology, physics, engineering, and materials science, can use nanotechnology.
Nanotechnology might be essential in the fight against environmental deterioration. However, manmade nanomaterials with completely new properties also have the potential to pose a threat to human health and the environment. Such dangers are still being explored due to the wide variety of nanomaterials that are being developed and their changeable nature.
The nanoworld offers researchers a wide range of materials beneficial for examining the very foundations of matter. These substances have distinct structures and adaptable qualities. They are therefore useful for a variety of real-world applications. The field of nanotechnology is still extremely young. By manipulating matter at the nanoscale length scale and taking advantage of novel processes and properties (physical, chemical, and biological) there, it is possible to develop useful/functional materials, technologies, and systems.
