What is a modern material?

Back

A modern material is a material developed through new or improved processes to enhance its properties, such as strength, speed, lightness, and toughness. They are often developed for specialist applications but can also be available for general use.

What are some examples of commonly used modern materials?

Back

Concrete, aluminium, and steel are commonly used modern materials.

What is graphene?

Back

Graphene is a single carbon layer material, hypothetically 100 times stronger than steel. It is almost weightless, potentially bulletproof, and invisible, but it has not been manufactured in large enough quantities to prove these properties.

How do liquid crystal displays (LCDs) work?

Back

LCDs use the light-modulating properties of liquid crystals to display images. The liquid crystals change shape when charged to block or let light through, requiring a backlight to work.

What are OLEDs and how do they differ from LCDs?

Back

OLEDs (organic light-emitting diodes) allow devices to be thinner and lighter as each pixel emits its own light, unlike LCDs which require a backlight. OLEDs offer better color and contrast but are more expensive.

What are nanomaterials and their uses?

Back

Nanomaterials are tiny particles (1 to 100 nm) used in thin films or coatings, such as oleophobic coatings on smartphone screens that repel fingerprints, or hydrophobic materials that repel water.

What are breathable fabrics and how do they work?

Back

Breathable fabrics allow body moisture to evaporate while remaining waterproof, using a breathable membrane with microscopic holes. Examples include Gore-Tex, Permatex, and SympaTex.
