Materials science is a highly interdisciplinary field, and materials scientists often specialize in specific areas based on their expertise and research interests. Here are some common types of materials scient
A conductor, or electrical conductor, is a substance or material that allows electricity to flow through it. In a conductor, electrical charge carriers, usuallyelectronsor charged ions, move easily from atom to atom whenvoltageis applied. Most metals like copper are considered good conductors, whil...
Thealuminum foil, steel wool, paper clip, copper, charcoal stick, and graphite pencil were good conductors and displayed metallic properties. The glass rod, plastic, rubber, and wood were poor conductors. Most of the samples with metallic properties contained metallic bonds. The exception was carbo...
Dielectrics are often confused with insulators. There are differences between these types of materials, however. The amount of charge that a capacitor can store -- its farad rating -- is directly related to the surface area of the conductors, how close together the conductors are and the abilit...
Why are materials such as wood, fur, feathers, and even snow good insulators? Good thermal conductors are also good electrical conductors. If so, why don't the connecting wires that are used to connect heaters get hot by conduction of heat from the heating element? What is a ...
The nuances of different capacitor types are, for the most part, determined by the characteristics of the dielectric used and the method by which a given device is constructed. All dielectric materials have limitations, with regard to the maximum applied field they can withstand for a given ...
Different sizes of conductors have different resistances, and the various materials we use to cover them have differentmaximum continuous conductor temperature ratings. Therefore there is a direct relationship between: Conductor size Insulation and coverings ...
Semiconductors are essential features of modern electronics, from computers and smart phones to bank cash machines and trains. They are used in the makeup of transistors.
What kind of materials are used for coating magnetic tapes? Classify each substance (I have to write which are elements and which are compounds). calcium, carbon dioxide, chalk, mercury, graphene, salt, sodium, sugar, water, zinc. Which organic compounds are mostly good conductors of electricit...
What type of elements are used to make n- type semiconductor? Often, when people have to work around radioactive materials spills, we see them wearing white coveralls (usually a plastic material). What types of radiation (if any) do you think these suits protect the worker from, and how?
