Nanochannel glass materials are an experimental mask technology that is an alternate method for fabricating nanostructures, although optical lithography is the predominant patterning technique. [ 1 ] Nanochannel glass materials are complex glass structures containing large numbers of parallel hollow channels.
5D optical data storage (also branded as Superman memory crystal, [1] a reference to the Kryptonian memory crystals from the Superman franchise) is an experimental nanostructured glass for permanently recording digital data using a femtosecond laser writing process. [2]
Nano-materials are often categorized as to how many of their dimensions fall in the nanoscale. A nanoparticle is defined a nano-object with all three external dimensions in the nanoscale, whose longest and the shortest axes do not differ significantly.
A nanotextured surface (NTS) is a surface which is covered with nano-sized structures. Such surfaces have one dimension on the nanoscale, i.e., only the thickness of the surface of an object is between 0.1 and 100 nm. They are currently gaining popularity because of their special applications due to their unique physical properties.
Nanocomposite is a multiphase solid material where one of the phases has one, two or three dimensions of less than 100 nanometers (nm) or structures having nano-scale repeat distances between the different phases that make up the material.
In 2014, researchers also fabricated glass nanofoam via femtosecond laser ablation. Their work consisted of raster scanning femtosecond laser pulses over the surface of glass to produce glass nanofoam with ~70 nm diameter wires.

4th Century Rome: The Lycurgus Cup was crafted using dichroic glass which is a product of nanoengineering; 6th-15th Centuries: Stained glass windows were created in European cathedrals which contained nanoparticles of gold chloride or other metal oxides or chlorides. These nanoparticles give the glass its vibrant colors.
