Researchers created a 2D material that is 20 times harder than steel.

The new nanomaterial looks like graphene, but it's the covalent organic framework or COF. The structure of COF is similar to graphene. But it's easier to make.

Graphene is a 2-dimensional single-atom layer of carbon. Graphite is a series of graphene towers. And that thing makes graphite a good source of graphene. But the problem is how to make enough graphene that it can cover some layers. The problem with 2D materials is that their abilities base the 2D structure. If there is more than one atomic structure in 2D material. And that means that the material loses its abilities.

So when the regular material will cover using 2D material. That 2D material must keep away from the layer. Nanotechnical pillars, atom-size sticks, or DNA bites that act as springs can separate those 2D layers from each other. Those things used keep the 2D atom layer out of the shell. Also if there is more than one 2D material layer. Those nano-pillars keep those structures separate.

That allows researchers to make multi-layer nano-structures where 2D material can keep its form. The difference between graphene and COF is that COF is a polymer. And polymers can grow like crystals. It's easier to make the COF layer by growing the structure than by using graphene. The ability to grow the structure of the COF network makes it possible to cover large size areas.

"Researchers have developed a method to retain the mechanical properties of 2D polymers called covalent organic frameworks (COFs) when stacked in multiple layers. By tweaking their molecular structure, the team created a lightweight material that is several times stronger than steel, preserving its 2D properties even in multilayered forms".

"Potential applications include filtration membranes and upgraded batteries. The research could also impact the design of ceramics and metals, potentially enabling their manufacturing and repair at lower temperatures". (ScitechDaily.com/ Molecular Magic – Researchers Develop Lightweight 2D Material Stronger Than Steel)

Researchers describe the COF like this:

"The potential applications are many. “COFs could make excellent filtration membranes,”. “For a filtration system, the functional group structure at the pore will be very important. As you have, say, dirty water traveling through a COF membrane, the functional group at the pore will capture the impurities only and allow the desired molecule to pass". (ScitechDaily.com/ Molecular Magic – Researchers Develop Lightweight 2D Material Stronger Than Steel)

"In this process, the mechanical integrity of that membrane will be very important. Now we have a way to design very strong, very fracture-resistant, multilayer 2D polymers that could be very good candidates for membrane filtration applications.” (ScitechDaily.com/ Molecular Magic – Researchers Develop Lightweight 2D Material Stronger Than Steel)

And by the way, the UFO story for the day. The 2D nanomaterial can revolutionize space technology.

In some visions, the developers planned to create a ball-shaped craft that is created by multiple layers of the 2D material. The idea is that the craft will use antimatter detonations for traveling. And the 2D material acts like ventilation. The idea is that there is no limit to the size of fullerene. The fullerene ball's size can be even kilometers.

The system is two internal large-size fullerene balls, and the system adjusts the symmetry of the exhaust jet by using electromagnetic fields that are aiming it in the right direction. And that thing makes it possible to change its direction very fast. The 2D materials can also use in the rocket engine nozzles. And they can make the system less noisy.

In some visions, the saucer-shaped space shuttle will equip with rocket engines that have graphene or some other 2D material net in the exhaust point of the nozzle. Then the very cold gas will pump in the exhaust gas that travels through that 2D network. That system makes it possible to create a silent and stealthy rocket that can be launched from near the city areas.

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 ...
