What are the uses for nanotechnology?



Nanotechnology is based on exploring, learning and creating at extremely small sizes. Nano a Greek word means dwarf. Science has far exceeded that a Nano today means 1 billionth of a meter. We have manipulated atoms at that size, creating amazing designs and using mathematics we are now creating materials that can self-replicate, self-assemble(amazing to watch).We are at the realm of great advance in Medicine(killing cancer without hurting healthy cells) ( keeping soldiers alive on battlefields with wound sealants and self-assembling life supporting devices), computing( quantum computers using super AI), communications ,space travel ( billions of Nano sized space ships travelling on laser beams at the speed of light too far off planets, self-assembling on those planets creating exploring laboratories, possibly mining rarest elements) , warfare( surveillance at the size of a blood cell), (super strong and super light weapons ) and unraveling the wonders of the quantum world. As materials get smaller especially in the Nano regions we have come to learn that they have more atoms on their surface area .This is opening new fields in energy, weapons, paints, clothes, etc. Someday everything will be a part of the nanotechnology revolution.

What are the differences between smart materials, composite materials and nano materials?

Image
Smart materials are at least dual function, composites are materials composed of dissimilar phases or components (sometimes they’re called hybrid materials now), and Nano materials have been engineered on the Nano-scale Smart materials have multiple functions, which generally include sensor/actuator ability in addition to having form, or being able to support at least some structural weight. The classic example is Nitinol, which is a Nikcle-Titanium allow. After mechanical deformation (for example, bending), it can be heated up and will return to the pre-deformed structural shape. Lead-Zirconate-Titanate (PZT) is a ceramic, which responds to mechanical deformation by generating an electrical potential. In the reverse, an applied electrical potential leads to a geometric expansion of the material (actuator function). Composites are materials that are combinations of at least two different materials, which allow the engineering of desired properties (like tailoring mechanic...

What are some examples of smart materials?

Image
Smart material are those that change in response to changing conditions in their surrounding or in the application of other directed influences such as passing an electric charge through them. Modern products increasingly use them, shirts that change colour with changes in temperature. Smart materials are the materials that have one or more properties that can be significantly changed in a controlled style such as stress, temperature, moisture, pH, electric or magnetic fields. There are many types of smart material some of which are already common. Some examples are as following: Types of smart material Some types of smart materials include: Piezoelectric   - On applying a mechanical stress to these materials it generates an electric current. Piezoelectric microphones transform changes in pressure caused by sound waves into an electrical signal. Shape memory   - After deformation of these materials they remember their original shape and return back to i...

How nanotechnology benefit the agriculture and allied sector?

Nanotechnology in agriculture  is the application of extremely small tools such as sensors, which can be used for agricultural development. Nanotechnology is a new revolution in industries and has the potential to bring about drastic changes in the agricultural industry . Development of new nanotech-based tools and equipment help increase efficiency and overcome challenges faced by the agricultural industry. Nanotech-based tools significantly benefit the agricultural sector; they aid in early detection of diseases, improve plant’s ability to absorb nutrients, and promote molecular treatment of diseases. Implementation of nanotechnology in the form of small sensors and monitoring devices have created positive impact on the future uses of precision farming methodologies. Nanoscale carriers can be utilized for the efficient delivery of fertilizers, pesticides, herbicides, and plant growth regulators. Its mechanism helps prevent degradation of plants, the...
