smart materials Flashcards
What are smart materials and how do they react to changes in their environment?
Smart materials have properties that respond to changes in their environment. This means that one of their properties can be altered by an external condition such as temperature, light, pressure, or electricity. This change is reversible and can be repeated many times.
What is Photochromic pigment and how does it react to UV light?
Photochromic pigment is a specially designed powder that changes color when exposed to a UV light source, but reacts best to direct sunlight. It appears white or colorless when not exposed to sunlight.
What is the function of fibre optics or optical fibre?
Fibre optics or optical fibre refers to the technology that transmits information as light pulses along glass or plastic fibres. A fibre optic cable can contain a varying number of these glass fibres, and another glass layer, called cladding, surrounds the glass fibre core.
What are some applications of nanotechnology?
The applications of nanotechnology commonly include industrial, medicinal, and energy uses. These include more durable construction materials, therapeutic drug delivery, and higher density hydrogen fuel cells that are environmentally friendly. Nanoparticles and nanodevices, due to their versatility and the ability to modify their physiochemical properties, have found uses in nanoscale electronics, cancer treatments, vaccines, hydrogen fuel cells, and nanographene batteries.
What does the use of smaller sized materials in nanotechnology allow for?
The use of smaller sized materials in nanotechnology allows for adjustment of molecules and substances at the nanoscale level.
How does the adjustment of molecules and substances at the nanoscale level influence the properties of materials?
The adjustment of molecules and substances at the nanoscale level can enhance the mechanical properties of materials
What does the use of nanotechnology in less physically accessible areas of the body imply?
The use of nanotechnology in less physically accessible areas of the body implies that it can be used to deliver treatments or perform medical procedures in these areas.
