The SLAC National Acceleration Laboratory created the most powerful X-ray laser.

    The SLAC National Acceleration Laboratory created the most powerful X-ray laser. 


Researchers are developing X-ray lasers because they offer new abilities for information, weapons, and material research. In communication tools X-ray lasers can use technology where the system sends highly accurate X-ray impulses to the two receivers. When the X-ray beam hits receiver A it gives a value of 1 (one). And when the X-ray beam hits receiver B the value could be zero (0). 

That kind of system requires AI-based kernels. But X-ray systems can communicate through walls. And that radiation is very hard to capture. So X-ray lasers provide a new and secure communication tool and they also can be used in photonic computing. The problem is that there are no mirrors that can reflect X-rays, and that makes X-ray lasers hard to develop.

One of these cryoplants, built specifically for LCLS ( Linac Coherent Light Source)-II, cools helium gas from room temperature all the way down to its liquid phase at just a few degrees above absolute zero, providing the coolant for the accelerator.

The most powerful X-ray laser is starting its actions. The system called Linac Coherent Light Source (LCLS) is the free-electron X-ray laser that can make coherent X-ray impulses. Those high-accurate impulses can be used to research atoms and make high-accurate R&D work with fundamental materials. 

The system can send millions of X-ray flashes in seconds. And that makes it possible to use that system in X-ray-based rapatronic technology. In that technology, the X-ray system uses X-ray movie cameras for collecting data from objects. The X-ray movie cameras are the cameras that use X-ray films. And they can observe the material's development. The X-ray rapatronic camera is a rapatronic camera that was developed for research nuclear tests. 

And in X-ray-based technology, those rapatronic cameras use X-ray films. Researching the internal structures of atoms and molecules requires very high-accurate X-ray impulses. The new X-ray lasers can be the most accurate systems that can follow the processes where crystals are forming. The thing is that there are many ways to create X-ray systems, and one of them is to use free electron lasers. The free electron lasers are particle accelerators where electrons travel meandering. Whenever an electron changes its direction it sends a photon. 

The benefit of free-electron lasers is this: the system can adjust the wavelength of their radiation. It is also possible to use cathode tubes that send radiation emission into the X-ray beam that travels in the middle of the system. So the system looks like the LRAD. The problem with cathode-based, solid-state systems is that they do not have enough high accuracy for high-class scientific work. However, weapon applications can use those X-ray lasers.

Researchers created the ability to mass-produce nanomaterial called "MXene".

  Researchers created the ability to mass-produce nanomaterial called "MXene". 


The nanomaterial "MXene" is the material that turns harder when somebody or something presses it. The "MXene" is one of the examples of 2D "molecular structures". When somebody talks about the 2D nanomaterial, normally people talk about the graphene, an atom layer of carbon. 

The "molecular 2D" structures mean that the material is one layer of molecules like lipids. Those lipide molecules are forming soap, and sometimes those lipids are used as tweezers in nanotechnology. But if engineers will cover the entire layer using one lipide layer that material will get new abilities. The thing that makes the nanomaterial interesting is its form. When somebody tries to push one layer-lipids that are in the same way together the lipide's "feet" are pushing against each other. 


"KIST researchers developed a method to predict molecule distribution on MXene, a nanomaterial, using its magnetoresistance property, paving the way for easier quality control and mass production. The research also highlighted MXene’s diverse applications based on the Hall scattering factor. Credit: Korea Institute of Science and Technology."

There is one thing that can revolutionize the armor and space technology. Those things are the "nanopyramids" the molecules that are forming a pyramid-shaped structure. If those pyramids are overlapping against each other. That thing makes it impossible to push anything through them if that material is created by using nanodiamonds. 

In some other versions, the material's molecule structure looks like a prism or gable roof. If two "roofs " are against each other overlapping. That thing makes material also very hard to penetrate because the structure turns harder when somebody pushes it. 

The nanotechnology is a tool that makes the new types of materials possible. Those nanomaterials can make the fundamental applications in civil and military products possible. The nanomaterial called "MXene" is one of the promising things for new types of armor. The nanomaterial's structure that you see in the image is like small "pyramids". 

When something hits or presses that material, the molecule's feet are pressing against each other. And that thing makes it hard to press that structure together. So the "MXene" is the material that turns harder when something presses it. That nanomaterial looks like soap lipids. When we think possibility of covering large surfaces by using one molecule layer of those lipids, that thing makes it possible to create a new type of surface, that can turn hard and stand against hard strikes.
