Silicon nanotechnology

What are silicon nanoparticles?

Silicon nanoparticles (SiNPs) are biologically compatible, metal-free quantum dots that exhibit size and surface tailorable photoluminescence.

What is Nano Tech used for?

Nanotechnology is being used in developing countries to help treat disease and prevent health issues. The umbrella term for this kind of nanotechnology is Nano -medicine. Nanotechnology is also being applied to or developed for application to a variety of industrial and purification processes.

What is nanotechnology and application of nanotechnology in battery?

Nanobatteries are fabricated batteries employing technology at the nanoscale, particles that measure less than 100 nanometers or 107 meters. It is hoped that nano-engineering will improve many of the shortcomings of present battery technology, such as volume expansion and power density.

Is Nano Tech possible?

In the future, nanotechnology could also enable objects to harvest energy from their environment. New nano -materials and concepts are currently being developed that show potential for producing energy from movement, light, variations in temperature, glucose and other sources with high conversion efficiency.

How do you make silica nanoparticles?

Spherical and amorphous silica nanoparticles can be prepared by the hydrolysis reaction of TEOS in ethanol using water and ammonia using sol-gel method. The particle size of nano silica can be controlled by adding span 20, span 40 and span 60 surfactants.

What are the dangers of using nanotechnology?

What are the possible dangers of nanotechnology? Nanoparticles may damage the lungs. Nanoparticles can get into the body through the skin , lungs and digestive system. The human body has developed a tolerance to most naturally occurring elements and molecules that it has contact with.
