Top Nano-Technology Inventions

I assume you have watched Avengers infinity war (27 April 2018), if you have; you may remember the scene where iron man wears his suit and then tell HULK, it’s nanotechnology. do you like it?

yeah, of course, I like nanotechnology, the ideas and concepts behind nanoscience and nanotechnology started with a talk entitled “There’s Plenty of Room at the Bottom”

It’s hard to imagine just how small nanotechnology is. One nanometer is a billionth of a meter or 10-9 of a meter. Here are a few illustrative examples:

  • There are 25,400,000 nanometers in an inch
  • A sheet of newspaper is about 100,000 nanometers thick
  • On a comparative scale, if a marble were a nanometer, then one meter would be the size of the Earth

Some Top inventions by nanotechnology are

1. Nano Bubble Water:skipping-rocks-lab-ooho-water-bottle-designboom-04-12-2017-818-008-818x518.jpg Do you know Americans alone throw around 35 billion plastic bottles per year!  To reduce this plastic waste we can switch to nanobubble water. The flexible, bubble-like packaging biodegrades in just 4-6 weeks, the same time as a piece of fruit. This can be flavored and colored, and can also be used for other liquids such as soft drinks, spirits, and cosmetics. 


2. Nanosensor Probe: nanoprobe-56b000135f9b58b7d01f52e0.gifA “nano-needle” with a tip about one-thousandth the size of a human hair pokes a living cell, causing it to quiver briefly. Once it is withdrawn from the cell, this ORNL nanosensor detects signs of early DNA damage that can lead to cancer. The ability for nanosensors to measure air quality, particularly for pollutants, is a new approach to air sampling. 

Nanosensors have already been used to measure solar irradiance, aerosol-cloud interactions, climate forcing, and other biogeochemical cycles of East Asia and the Pacific region.

3. Nano-Biomaterials: Using nanotechnology to design a self-cleaning plastic in which Hydrogen_Fuel_Production_Nano-Sized_Biomaterial_1-770x437.jpgthe enzyme molecules are an integral part of the material. When the plastic comes into contact with bacteria or other pathogens, the enzymes attack the microbes and destroy their ability to bind to its surface. Many inorganic materials and plastics excel at conducting electricity or emitting light. Biological materials, on the other hand, are excellent at recognizing other molecules with exquisite sensitivity and can spontaneously assemble themselves into numerous complex structures. “Putting the two together will lead to some unique applications,” says Dordick.

Catherine Hockmuth of UC San Diego reports that a new biomaterial designed for repairing damaged human tissue doesn’t wrinkle up when it is stretched. This biofabrication technique uses light, precisely controlled mirrors and a computer projection system — shined on a solution of new cells and polymers — to build three-dimensional scaffolds with well-defined patterns of any shape for tissue engineering.

4. ThemoPower: MIT scientists at MIT have discovered a previously unknown phenomenon that can cause powerful waves of energy to shoot through minuscule wires known as carbon nanotubes. The discovery could lead to a new way of producing electricity. The phenomenon, described as thermopower waves, “opens up a new area of energy research, which is rare,” says Michael Strano.

Carbon nanotubes (as illustrated) are submicroscopic hollow tubes made of a lattice of carbon atoms. These tubes, just a few billionths of a meter (nanometers) in diameter, are part of a family of novel carbon molecules, including buckyballs and graphene sheets.In the new experiments conducted by Michael Strano and his team, nanotubes were coated with a layer of a reactive fuel that can produce heat by decomposing. This fuel was then ignited at one end of the nanotube using either a laser beam or a high-voltage spark, and the result was a fast-moving thermal wave traveling along the length of the carbon nanotube like a flame speeding along the length of a lit fuse. Heat from the fuel goes into the nanotube, where it travels thousands of times faster than in the fuel itself. As the heat feeds back to the fuel coating, a thermal wave is created that is guided along the nanotube. With a temperature of 3,000 kelvins, this ring of heat speeds along the tube 10,000 times faster than the normal spread of this chemical reaction. The heating produced by that combustion, it turns out, also pushes electrons along the tube, creating a substantial electrical current.

5. Agriculture: Currently, the world population is growing at 1.13 percent per year, with an estimated 7.4 billion people in the world today. Experts predict this number will continue to rise to more than 90 billion by 2050, with the largest population increase expected to occur in less developed countries (Population Reference Bureau). These predictions have world leaders, including the Food and Agriculture Organization of the United Nations, anticipating significant increases in food demand and rising pressure for healthy crops in developing countries.

In response to these growing population concerns, scientists in the nanotechnoloy and nanoagriculture fields are focused on determining how nanosized particles can increase crop and livestock productivity. While nanoagriculture is a more recent application of nanotechnology, the benefits are clear with its “potential to protect plants, monitor plant growth, detect plant and animal diseases, increase global food production, enhance food quality and reduce waste.”

6. Energy Storage-Solar Power:download.jpg Solar power is the future of energy storage, but it comes with a hefty price tag. As of 2014, solar energy accounts for less than one percent of electricity in the United States and it costs twice as much to produce compared to natural gas. Despite the costs associated with solar energy, the benefits are significant, including sustainability and low maintenance.

In an effort to accelerate solar power advancements, researchers are applying nanotechnology to solar energy. For example, nanoparticles “have been shown to enhance the absorption of light, increase the conversation of light to electricity, and provide better thermal storage and transport (National Nanotechnology Initiative).” With these advancements, nanotechnology has the potential to improve solar energy efficiency and reduce costs.

7. Stronger Materials/Higher Strength Composites: The next generation of graphene and carbon nanotube-based devices will lead to even lighter but stronger structures that have been made possible by carbon fiber and will become increasingly obvious in cars, bicycles, and sporting equipment, says Clint Landrock, chief technology officer of NanoTech Security.

Dr. Samuel Brauer, founder Nanotech Plus, an alliance of consultants offering analysis and operational assistance about the business of nanotechnology, cites as one area of advancement the development of carbon nanotube pre-impregnated materials which offer better conduction, overcoming one of the major challenges of conventional carbon fiber/epoxy composites. He notes that carbon nanotube meshes have already flown on some space missions.
