The new light-driven polymers are impressive.

To make the system act as the user wants, the user must control the system. The ability to control a system requires the ability to see things that happen inside the system.

Japanese researchers catch azo-polymer film's interaction with light using a high-speed atomic force microscope and laser-irritation system to observe that thing. The light-driven polymers in some films might not seem very impressive. But those films or their polymers can be used as "glue" for other structures. In self-assembling structures, polymers are as glue on the edge of parts.

Then light will activate the contact layers between those polymers. The light-activating polymers can make it possible to create long polymers. The polymerase chain reaction will make it possible to create nano-scale structures. And light can be a good tool to adjust the speed of that reaction.

If there is some kind of nano-electric system those systems can be the tool for nanotechnical self-assembly structures. Electric fields on the film make it possible to move nanomachines on it.

By adjusting the light's brightness the system can adjust the electric level in that system. The simplest way to transform light into electricity is to cover the film using silicone. That silicone makes the light-electric phenomenon on the film. And that thing makes it possible to adjust the electric production of the film. That kind of photo-electric can deliver electricity to nano-size microprocessors.

In those nano-electric systems a small size benzene, with small magnetic iron bites can form the miniature generator's frame. And there is an axle that spins in that frame. That system can act as a miniature generator for nanotechnical solutions. Maybe one of them is not very impressive, but a large number of nanogenerators can create a strong electric force.

Long polymer-metal chains that are in long polymer-metal tubes, there is a magnetic field. That can create very thin but long generators. Engineers can install those generators in structures. Rising air or pressure impulses created using acoustic systems can rotate nano- or miniature generators.

Plasmonic waves can make new waves in quantum technology.

"LSU researchers have made a significant discovery related to the fundamental properties and behavior of plasmonic waves, which can lead ot the development of more sensitive and robust quantum technologies. Credit: LSU" (ScitechDaily, Plasmonics Breakthrough Unleashes New Era of Quantum Technologies) Plasmonic waves in the quantum gas are the next-generation tools. The plasmonic wave is quite similar to radio waves. Or, rather say it, a combination of acoustic waves and electromagnetic waves. Quantum gas is an atom group. In those atom groups, temperature and pressure are extremely low. The distance of atoms is long. And when an electromagnetic system can pump energy to those atoms. But the thing in quantum gas is that the atoms also make physical movements like soundwaves. It's possible. To create quantum gas using monoatomic ions like ionized noble gas. In those systems, positive (or negative) atoms push each other away. When the box is filled with quantum gas and som

What is the difference between TR-3A and TR-3B? And are those planes real?

What is the difference between TR-3A and TR-3B? And are those planes real? Is TR-3B (0) "Black Triangle UFO" or is it only the piece of paper? The study project, what is used to create advanced ideas for use of the nuclear-powered aircraft. Or is it the study project or black budget aircraft, where lost 2,3 trillion dollars (1)of the stealth bomber were gone. In this text is things, that might seem very difficult to accept, and when we are thinking about things like doubling the object or making it smaller by using huge layers of energy, nothing denies to test those things. But were those tests successful, there is no data about that in public Internet, so we must say that things like doubling the human or aircraft can be tested, but the results can be unknown. But in the source two is the tale, what seems like impossible, those men, who got Noble Prize put at first time one atom to the box, and hit it with photon one photon in the box and hit it with t

The interesting coincidence between USS Sea Shadow (1982) and CSS Virginia (1862)

Image I The interesting coincidence between USS Sea Shadow (1982) and CSS Virginia (1862) Far away from its time is the thing, that you might notice when you see those two images. The upper one (Image I) is portraying the modern naval USS Sea Shadow (IX-529)(1) experimental Stealth ship, which was created by Lockheed-Martin, and the image below (Image II) is portraying the CSS Virginia (2), the ironclad from the Civil War Era. The thing why the hull of the CSS Virginia, what is ironclad from 1862 is that the ammunition of the cannons would not transfer their impact energy to the hull of the ship. And the reason why Sea Shadows hull has this form is that it should point the radar echo away from the hull. The thing that I must say that CSS Virginia is far ahead its time because that structure is effective against the explosive ammunition, and the slanting armor of tanks like T-34 and Sherman have made them effective. But for some reason, the use of slanting armor has
