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 – …
MXene - what is it, how it is made, what it is used for - Nanowerk
MXenes are ceramics that comprise one of the largest families of two-dimensional materials. MXenes are made from a bulk crystal called MAX. Unlike most 2D ceramics, MXenes have inherently good conductivity because they are molecular sheets made from the carbides and nitrides of transition metals like titanium.
Fullerenes (Buckyballs): Nanotechnology Definition, Uses, Properties
Definition: Fullerene, commonly known as buckyball, is a form of carbon molecule that resembles a soccer ball, composed of carbon atoms linked in hexagonal and pentagonal shapes.This article explores the structure, properties, synthesis, applications, and challenges associated with fullerenes, particularly focusing on the spherical variety known as buckyballs.
Understanding Thin Films: Key to Advanced Electronics
Definition: Thin films are critical layers of material, from a few nanometers to several micrometers thick, deployed across technology, electronics, and energy sectors. Their importance lies in their ability to alter the physical properties of surfaces in ways bulk materials cannot, primarily due to their reduced dimensions.
Nanofiltration explained - definition and examples - Nanowerk
Nanofiltration is a type of membrane filtration process that is used to separate molecules based on size. It is one of the four membrane technologies that utilize pressure to effect separation of contaminants from water streams but it is more selective in the types of molecules it can filter out.
Nanoelectronics - Definition and Applications - Nanowerk
Nanoelectronics covers a diverse set of devices and materials, with the common characteristic that they are so small that physical effects alter the materials'properties on a nanoscale – inter-atomic interactions and quantum mechanical properties play …
Understanding Nanofibers: Essential Guide to Their Science
Electrospinning: The most widely used method for producing nanofibers, electrospinning uses an electric field to draw charged threads of polymer solutions or melts into fine fibers. This method offers versatility in controlling fiber diameter, orientation, and composition. Forcespinning: A newer technique that utilizes centrifugal force to draw fibers from polymer melts or solutions, offering ...
Nanorods: Elongated Nanostructures with Unique Properties
Nanorods are elongated nanostructures with a diameter in the nanometer range and an aspect ratio (length-to-width ratio) greater than one. They are typically characterized by their unique optical, electrical, and magnetic properties that arise from their anisotropic shape and quantum confinement effects.
Nanosecond and the Ultrafast World of Time - Nanowerk
Specific Examples to Illustrate the Nanosecond. Computer Processors: Modern computer processors operate at gigahertz (GHz) frequencies, with each cycle taking just a few nanoseconds.This illustrates the nanosecond's relevance in computing, where it helps quantify processing speeds and time operations.
What are Nanomaterials - Nanowerk
Materials reduced to the nanoscale can suddenly show very different properties compared to what they show on a macroscale. For instance, opaque substances become transparent (copper); inert materials become catalysts (platinum); stable materials turn combustible (aluminum); solids turn into liquids at room temperature (gold); insulators become conductors (silicon).
