If you don't consider advances in materials technology to qualify as new technology, it is difficult to give you a satisfactory answer.

I don't consider altercations or improvements to an existing technology to be 'new technology'. Just like I don't consider the remake of a song to be 'a new song'. It may be on a new album by a new artist, and the song is new to the artist themselves, and that song make new money for that new artist; it still is an old song.

 

That is very weird. The glass like lithium atop the lithium for faster ion exchange. I had a conversation with a fellow student about "lubricating" copper with an alloy to speed electrons along a wireset. Using an alloy sandwiched between two flat copper wires, you could theoretically speed the transmission rate. The electrons would travel in the junctions rather than in the wire.

This would be also be possible with a ferrous metal atop a non-ferrous metal, keeping the electron flow in the junction of a ferrious/nonferrous sandwich.
