Graphene Explained: A Beginner's Guide to its Properties
Graphene has emerged as one of the most promising nanomaterials because of its unique combination of exceptional properties: it is not only the thinnest but also one of the strongest materials; it conducts heat better than all other materials; it is an excellent conductor of electricity; it is optically transparent, yet so dense that it is impermeable to gases – …

what they are, how they are made, what they are used for
Carbon nanotubes are cylindrical molecules that consist of rolled-up sheets of single-layer carbon atoms (graphene); they possess unique properties like high aspect ratio, mechanical strength, electrical and thermal conductivity, chemical stability, and a tip-surface area near the theoretical limit. They are one of the strongest materials known to man.
Beyond Rayleigh: Mie Scattering and Its Importance for
The scattering behavior of a particle depends on its size relative to the wavelength of the incident light. When the particle size is much smaller than the wavelength (typically less than 1/10 of the wavelength), the scattering is described by Rayleigh scattering, which is a simpler case of Mie scattering.As the particle size becomes comparable to or …

A Guide to Optical Lithography's Role in Technology - Nanowerk
Definition: Photolithography, also known as optical lithography, is a micro- and nanofabrication process widely used in semiconductor manufacturing and various nanotechnologies to create intricate patterns on a substrate, typically a silicon wafer. This technique employs light to transfer a geometric pattern from a photomask to a light-sensitive chemical photoresist on the substrate.
MEMS Explained - A Comprehensive Guide to ... - Nanowerk
MEMS is an acronym that stands for microelectromechanical systems – exceptionally small devices that incorporate mechanical, electrical, and frequently optical components on a single microchip. These devices, despite their micro scale, perform a wide array of functions, from sensing and actuating to data processing and communication.
