Holman's nanoparticle coating tool works like an aerosol can of spray paint. But instead of spraying liquid droplets of paint, it sprays nanoparticle dust 😉
In 2016, Holman had the idea to use coatings of nanoparticle dust to enhance the efficiency of tandem solar cells. Soon after, he and his research team realized other industries could improve their products by applying nanoparticles to their surfaces.
“The more we look, the more we find,” Holman said.
One day you might have cheaper solar panels, cleaner windows and bandages that accelerate healing thanks to nanoparticle dust applied using Holman’s innovative spraying tool.
1. ( Celestial Objects) the diffuse band of light stretching across the night sky that consists of millions of faint stars, nebulae, etc, within our Galaxy.
a band of light
This frequency range is divided into separate bands, and the electromagnetic waves within each frequency band are called by different names;
beginning at the low frequency (long wavelength) end of the spectrum these are: radio waves, microwaves, infrared, visible light, ultraviolet, X-rays, and gamma rays at the high-
A gamma ray, or gamma radiation (symbol γ) is a penetrating form of electromagnetic radiation arising from the radioactive decay of atomic nuclei. It consists of the shortest wavelength electromagnetic waves and so imparts the highest photon energy.

In antenna theory, a phased array usually means an electronically scanned array; an array of antennas which creates a beam of radio waves which can be electronically steered to point in different directions, without moving the antennas.4 Jun 2017

The Rod and ring symbol is a symbol that is depicted on Mesopotamian stelas, cylinder seals and reliefs. It is held by a god or goddess and in most cases is being offered to a king who is standing, often making a sacrifice, or otherwise showing respect.
The symbol dates from the Sumerian Renaissance to the Neo-Assyrian Period, and is commonly explained as a coil of measuring string and a yardstick.[1] Other theories are that they are a shepherd's crook and a nose rope,[2] or that the ring is no rope at all.[3]
