Nanomaterials are used in many everyday products. Navigate the flat and find out where and why.
Test your nanomaterials' knowledge
Pillow cases can be coated with nanosilver to make them more resistant to bacteria.
Pillow cases can be coated with nanosilver to make them more resistant to bacteria. Many mountain jackets and spill-proof tablecloths are coated with synthetic amorphous silica to make them water resistant. More
Nanomaterials are only formed through industrial manufacturing
Nanomaterials occur in nature, for example, in dusts and volcanic ash. They can also result unintentionally from human activity, such as in car exhaust, or from burning candles. For many years, some nanomaterials have also been produced by industry. With the help of science, we are now also able to artificially produce such particles or materials by using engineering at the atomic level ('bottom-up' processes). More
Which of the following is smaller than or equal in size to a nanomaterial?
Which of the following is the most commonly used nanomaterial in sports equipment?
In sports equipment, carbon nanotubes are the most widely used nanomaterial. They are used to produce lighter but at the same time more rigid equipment. More
Which of the following is not a reason for nanomaterials being used in coatings and paints?
Paints and coatings contain nanomaterials to make them easier to clean, harder to scratch, or last longer. They can also be used as water or dirt repellent.
The most commonly used nanomaterials in paints and coatings are nanoscale titanium dioxide and silicon dioxide. Titanium dioxide is used in coatings for self-cleaning surfaces. Adding silicon dioxide to paint can improve its hardness and its abrasion, scratch and weather resistance. More
A nanomaterial used in a cosmetic product in the EU needs to be marked on the label with the word “nano” in brackets after the name of the ingredient.
You can find out if the cosmetic product you are using contains nanomaterials by looking at the list of ingredients on the package of the product. Nanomaterials in a cosmetic product must be labelled with the word “nano” in brackets after the name of the ingredient. More
How many times smaller are nanomaterials compared to the diameter of a human hair?
Nanomaterials are special for several reasons, but in particular for one – their size. Nanomaterials are up to 10 000 times smaller than the width of a human hair, and this tiny size makes them very valuable for all kinds of practical uses. More
Why is titanium dioxide used in sunscreen?
Nanomaterials are used in a great number of consumer products. Titanium dioxide is used in sunscreen as a UV filter to protect us from sunburn. More
Nanosilver has antibacterial properties.
The good thing about nanosilver is that it reduces bacterial growth, which will make your clothes smell less once you get to the top of that hill on your bike. More
How can nanomaterials enter our bodies?
Nanomaterials can enter your body in three different ways: you can inhale them, ingest them with your food and drink, or they can be absorbed through the skin. More
Nanomaterials are used to keep solar panels clean and to increase the amount of the Sun’s energy that they absorb and convert into electricity.
Sunscreen is not the only link between the Sun and nanotechnology. Nanotechnology is also used to make solar panels work better. Nanomaterials help keep the panels clean and they also increase the amount of the Sun’s energy that the panels are able to absorb and convert into electricity. More
Computers and TV screens are lighter thanks to nanotechnology, but they now use more power.
Computers and TV screens are lighter and use less power thanks to nanotechnology.
Nanomaterials are also used to create computer chips and to reduce the size of transistors in circuit boards. Thanks to nanotechnology, computers are faster and more files can be stored on hard drives and portable storage devices than before.More
