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.
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.

Nanosensors - what they are; what they do - Nanowerk
Apart from metal nanoparticles, optical nanosensors based on fluorescence measurements have been built with semiconductor quantum dots and other optical sensors have been developed with nanoscale probes that contain dyes whose fluorescence is quenched in the presence of the analyte to be determined; nanoparticle films have been used for gas sensors; magnetic nanoparticles bound to ...
Nanocoatings - Definition and Applications - Nanowerk
Nanocoatings are nanoscale thin-films that are applied to surfaces in order create or improve a material's functionalities such as corrosion protection, water and ice protection, friction reduction, antifouling and antibacterial properties, self-cleaning, …
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.
Carbon Nanotube Manufacturers and Suppliers - Nanowerk
Carbon nanotubes (CNTs) come in a variety of diameters, lengths, and functional group content. CNTs today are available for industrial applications in bulk quantities of metric ton quantities. Several CNT manufacturers have >100 ton per year production capacity for multi walled nanotubes. A nanotube ...
What are perovskites and their applications - Nanowerk
A defining moment came in 2012, when Professors Henry Snaith at the University of Oxford and Michael Graetzel at the Federal Institute of Technology Lausanne, building on the work of Tsotomu Mayasaka from Tokyo, found that solar cells with perovskite as the active component could be made with greater than 10% power conversion efficiencies for turning the sun’s rays into electrical energy.
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 …
