Understanding Nanoscale

We do not see objects or measure distances in the nanoscale in our daily life. Comprehension of the nanoscale (a very very small scale) is only possible with fun examples resembling nanoscale.


Making Origami Buckyball

A buckyball is a molecule containing 60 carbon atoms. Each carbon atom is bonded to three adjacent carbon atoms, and the entire grouping forms a sphere. This unique molecular shape and composition is useful in many of applications.

Nanocrystal Fabrication

Research on nanocrystalline materials has increased enormously during the past years. The intense investigations are stimulated by several envisaged application areas for this new class of materials. For example, the novel optical, electrical, and mechanical properties of devices comprising nanocrystallite semiconductors and oxides have been demonstrated in photovoltaic solar cells, light-emitting diodes, varistors, and ceramics. Other applications include ion insertion batteries and electrochromic devices.

Lotus Effect

The lotus effect refers to the very high water repellence exhibited by the leaves of the lotus flower. Dirt particles are picked up by water droplets due to a complex micro- and nanoscopic architecture of the surface, which minimizes adhesion. Some nanotechnologists have developed treatments, coatings, paints, roof tiles, fabrics and other surfaces that can stay dry and clean themselves in the same way as the lotus leaf.


Iron Nanoparticles and Ferrofluids

Nanoscale iron particles are sub-micrometer particles of iron metal. They are highly reactive because of their large surface area. In the presence of oxygen and water, they rapidly oxidize to form free iron ions. Ferrofluids are colloidal liquids made of nanoscale ferromagnetic, or ferrimagnetic, particles suspended in  an organic solvent or water.

Waves and Dancing Ferrofluid

This experiment is aimed to provide an understanding of how the particles act in changing magnetic field. If there is no magnetic field, ferromagnetic nanoparticles are random. When we applied magnetic field around the test tube, ferromagnetic nanoparticles respond the field and the magnetic moments of particles align with the magnetic field lines.

LED (Light Emitting Diodes)

This experiment explores the physical phenomenon of LEDs, how they operate, their unique features, together with the characteristics of light.  LEDs are environmentally friendly, ultra-efficient electronic (or semiconductor) lighting devices that emit cooler, softer and/or more natural light with relatively the least consumption of watts when electrical current passes through them.

Carbon Nanotubes

The carbon atom seems to be the most wonderful of all the elements in the periodic table. As well as being the basis of life, it is one of the most important building blocks of nanotechnology. Carbon nanotubes, composed of interlocking carbon atoms, are 1000 times thinner than human hair and can be 100 times stronger than steel. The amazing properties of carbon nanotubes provide many application areas.

Waveguide Fabrication by Sol-Gel

This experiment is aimed to provide an understanding of sol-gel, its products, including fiber optics used in the internet communication. Fiber Optics is a data-delivery system transmitting light and sound through glass fibers. In telecommunications, the fiber optic technology has replaced the copper-wire technology by delivering information 1000 times faster and 100 times farther.

Nanocamp Activity - Silver Mirror

The “Silver mirror” lesson explores the properties of silver and its compounds as well as its opportunity to be used as material for nanoparticles and their usage, and the history of mirrors and how can they be produced.
