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 – …
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.
MOF Metal Organic Framework - definition, fabrication and use
Metal-organic frameworks (MOFs) are organic-inorganic hybrid crystalline porous materials that consist of a regular array of positively charged metal ions surrounded by organic 'linker' molecules. The metal ions form nodes that bind the arms of the linkers together to form a repeating, cage-like ...
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.
Transistors explained - what they are and what they do - Nanowerk
A transistor – a word blend of "transfer" and "resistor" – is a fundamental component of today's advanced electronics. Essentially, a transistor, as one of the foundational elements of modern electronic devices, is made up of three layers of a semiconductor material, typically silicon, each layer possessing a different charge.
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.
Aerogels Explained | Ultralight Materials Transforming Technology
Introduction to Aerogels: Aerogels are ultralight materials characterized by their extreme porosity and low density. Often referred to as "frozen smoke" for their translucent appearance, these materials boast remarkable properties, including excellent thermal insulation, low dielectric constant, and high specific surface area, making them ideal for a range of applications from energy storage ...
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.
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.
CMOS Technology - Nanowerk
Complementary Metal-Oxide-Semiconductor (CMOS) technology is a vital part of modern electronics, used in designing and manufacturing integrated circuits (ICs) that power many digital devices. CMOS technology combines two types of transistors that work together, leading to efficient power use and ...
