Nanochemistry

Nanochemistry Nanochemistry is the study of chemistry at the nanoscale. One billionth of a meter is one nanometer. To further understand this extremely small length, a human hair may be demonstrated to be one hundred thousand nanometers thick. At least one dimension of a material must be 1-100 nm for it to be termed a nanomaterial.

Nanoscience and Nanotechnology

Although the principles of nanoscience and nanotechnology have been recognized in scientific and industrial circles for much longer, they have only recently become known to far wider portions of society. In fact, the use of these technologies to produce more and varied items has proven beneficial in this regard. Sunscreen, for example, is a well-known example. Nanoparticles provide UV protection for these products. The vast surface area of nanoparticles efficiently absorbs damaging UV radiation in sunscreens.

The Emergence of Nanochemistry

Long before the term nanotechnology came into use, the ideas and concepts behind nanoscience and nanotechnology started with the speech of Nobel laureate and famous American theoretical physicist Richard Feynman's "There's Plenty of Room at the Bottom" at the American Physical Society meeting on 29 December 1959 at the California Institute of Technology (CalTech). Feynman described a method for scientists to manipulate and control individual atoms and molecules in his address. Professor Norio Taniguchi coined the term nanotechnology more than a decade later while researching ultra-precision machining. The scanning tunneling microscope, which can "see" individual atoms, was invented in 1981, which is regarded as the beginning of modern nanotechnology. The concept of "there is a lot of room at the bottom" popularized by Richard Phillips Feynman drew attention to the relevance of nanochemistry and led to a surge in research in this sector. Chemistry in nanotechnology is about achieving more with less material. As a result, nanochemistry is critical to the long-term growth of our economy and society. Nanochemistry Applications Nanotechnology applications are realizing the promise of nanotechnology to help society in both predictable and unforeseen ways after years of research and development. Many technological and business areas, including information technology, homeland security, medical, transportation, energy, food safety, and environmental research, are benefiting from nanotechnology. We shall try to provide some examples of nanotechnology's rapidly expanding advantages and uses.

Everyday Materials and Processes

The capacity to manipulate the structures of materials at extremely small scales to obtain specific properties is at the heart of nanotechnology's many benefits, considerably expanding the materials science toolset. Materials can be made stronger, lighter, more durable, reactive, sieve-like, or better electrical conductors using nanotechnology, among other features. Many ordinary commercial products based on nanoscale materials and techniques are now on the market and in use. Nanoscale additions or surface treatments to textiles can provide minor ballistic energy deflection or help them resist wrinkling, staining, and bacterial growth in personal body armor. Transparent nanoscale coatings over eyeglasses, computer and camera displays, windows, and other surfaces can make them water and residue repellent, anti-reflective, self-cleaning, UV or infrared light resistant, anti-fog, antimicrobial, scratch-resistant, or electrically conductive. Washable, durable "smart textiles" integrated with flexible nanoscale sensors and electronics for health monitoring, solar energy collection, and energy harvesting through motion are being developed. Nanochemistry applications for lightening aircraft, watercraft, and spacecraft can result in considerable fuel savings. Nanoscale additions in polymer composite materials are used to make lightweight, stiff, durable, and flexible baseball bats, tennis rackets, bicycles, motorcycle helmets, automotive components, luggage, and power tool enclosures. Carbon nanotube sheets are presently being manufactured for use in future aircraft. Because of their lightness and conductivity, they are suited for applications such as electromagnetic shielding and thermal control. Enzyme nano-bioengineering can be derived from wood chips, corn stalks, unmodified perennial grasses, and other sources. Its goal is to make it possible to convert cellulose to ethanol for fuel. Cellulosic nanoparticles have shown promise in a wide range of industries, including electronics, construction, packaging, food, energy, healthcare, automotive, and military. Cellulosic nanoparticles are expected to be less costly than many other nanomaterials and to have a high strength-to-weight ratio, among other benefits. High-power rechargeable battery systems, thermoelectric materials for temperature control, tires with lower rolling resistance, high efficiency/low cost sensors and electronics, thin-film smart solar panels, and fuel additives for cleaner exhaust and extended range are among the nano-engineered materials used in automotive products.
