Graphene Explained: A Beginner's Guide to its Properties
网页Graphene is a single layer of carbon atoms arranged in a hexagonal lattice structure, forming a two-dimensional (2D) material. It has exceptional mechanical, electrical, and thermal properties, and is widely studied for its potential use in various fields such as electronics, energy storage, and biomedicine.
what they are, how they are made, what they are used for
网页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.

What is smart dust and how is it used? - Nanowerk
网页Smart dust senses and records data about its environment such as light, temperature, sound, presence of toxins or vibrations, and transmits that data wirelessly to larger computer systems. Smart dust is a vision of the networked future where intelligent networks of trillions of miniscule sensors continuously feel, taste, smell, see, and hear ...
What are nanobots? Explaining nanorobotics and nanorobots
网页However, in medical nanotechnology, the term nanobot or nanorobot is used to describe programmable molecules that can perform specific tasks. These nanobots are a reality and are being actively researched and developed. The field of nanorobotics involves the design, creation, and control of these nanoscale programmable molecules.
Electronegativity explained - Nanowerk
网页Electronegativity is defined as the tendency of an atom to attract electron density, i.e., to polarize the chemical bond. The most widely used scale is the thermo-chemical Pauling’s scale, where electronegativities have units of eV 1/2. Electronegativity is a derived quantity, so it is not directly measurable.
MXene - what is it, how it is made, what it is used for - Nanowerk
网页MXene uses and applications. MXene could be used in energy storage devices such as electrodes of Li-ion batteries, pseudo capacitors, etc. The researchers also envision its use as reinforcement in composites, similar to clays or graphene, which increase mechanical properties and decrease gas permeability of polymers.
Triboelectric effect - Nanowerk
网页The triboelectric effect is a type of contact electrification where materials become electrically charged after they have been in contact with another material and are then separated. Rubbing the two materials together enhances the contact between their surfaces, amplifying the triboelectric effect. Everyday examples include rubbing a glass rod ...
