Atomic-Scale Nanowires Can Now Be Produced At Scale (phys.org) 13
fahrbot-bot shares a report from Phys.Org: Researchers from Tokyo Metropolitan University have discovered a way to make self-assembled nanowires of transition metal chalcogenides at scale using chemical vapor deposition. By changing the substrate where the wires form, they can tune how these wires are arranged, from aligned configurations of atomically thin sheets to random networks of bundles. This paves the way to industrial deployment in next-gen industrial electronics, including energy harvesting, and transparent, efficient, even flexible devices.
Using a process called chemical vapor deposition (CVD), they found that they could assemble TMC nanowires in different arrangements depending on the surface or substrate that they use as a template. Examples are shown in Figure 2; in (a), nanowires grown on a silicon/silica substrate form a random network of bundles; in (b), the wires assemble in a set direction on a sapphire substrate, following the structure of the underlying sapphire crystal. By simply changing where they are grown, the team now have access to centimeter-sized wafers covered in the arrangement they desired, including monolayers, bilayers and networks of bundles, all with different applications. They also found that the structure of the wires themselves were highly crystalline and ordered, and that their properties, including their excellent conductivity and 1D-like behavior, matched those found in theoretical predictions. The research has been published in the journal Nano Letters.

In between making PS5 controllers Sony found time to invent this. Amazing how those Japanese don't get mixed up. Someone send a Nobel to Shigeru Miyamoto.

I can do that at 10,000,000,000X scale!

Manipulating atoms like this will create a whole new world for us. Not sure if that is good or bad.

Most nano-particles developed to date are generally bio-toxic. Should be easy to draw the conclusion.

Actually, with the execption of a small number of patients who have cardiac-cell complications (which are reversible for the most part) Herceptin (aka Trastuzumab [wikipedia.org]) is highly-targeted to breast cancer cells that express the HER2+ surface protein. It has no systemically-toxic side effects, otherwise.
(Full disclosure: my wife had double HER2-positive invasive tubal carcinoma, which used to be invariably fatal. It was completely cured by a short course - 3 months worth - of Herceptin. It's bee

Generally both, but more good than bad.
We like to focus on the negative, but here and as a culture, but generally speaking scientific and engineering progress improves our lives, not detracts from it.
