The breakthrough in material science.


"Researchers have developed an innovative tool that accelerates the design of auxetic materials—materials that expand when compressed and contract when stretched. This could lead to broader applications in products requiring impact resistance and comfort, such as safety gear and apparel.

The science known as auxetics researches the stretching of material.  Materials like rubber are auxetic materials because you can stretch that material. In normal situations, the auxetic materials turn thinner when somebody stretches them. But what if the material turns thicker? Or material stretches like that surface area turns larger. That thing makes it possible to create new solutions. 

That stands for mechanic and electromagnetic stress in a new way. When the surface area of material grows the distance of its particles grows. That forms energy pockets where energy can go. The problem with dense materials is that if energy impact hits dense materials. And that impact is strong enough that pushes the material particles away from each other. 

The big weakness of regular graphene is that it forms standing waves in the structure. The small sticks can used to conduct that energy away from graphene. Those sticks can pull energy out from the graphene layer. But if the edges of that 2D structure are put in the fullerene balls that allows the graphene to expand. When the end of the carbon chain is freely in the fullerene. That ball is allowed to move inside it. 

What would you do with the material where an impact energy travels only horizontally? If that kind of material is possible to make that would be the biggest advance in material technology. If all impact energy travels horizontally. That means the energy will not conduct to the structure below the layer. That kind of structure requires space at its side, which allows it to expand horizontally. 


Normal material (Above) and auxetic material (below). Theoretically is possible to create the auxetic version of the 2D carbon. Graphene is a regular material, even if it's fundamental. "The auxetic fullerene" requires that the carbon atoms form a structure that is similar to the image below introduces.

Normally when a particle hits material it transfers energy in it. That impact energy makes a pothole in the material. Theoretically is possible to make material. Their impacts don't make those potholes.  That requires the possibility of making the material. There an impact energy travels only horizontally on layer. That thing requires the spring structure that impacts energy can't push down. If the material transfers impact energy only horizontally that thing makes it possible to create the new types of armor.

The new types of graphene can be the base of that thing. In that graphene, the carbon atoms should form the spring-looking structures. That spring gives new features to the material. 

But how to protect materials against heat and electromagnetic stress? The idea is that the material forms a mosaic-like structure. And at the side of all of those bricks or blocks is a lower energy area. That thing can conduct thermal energy out from the brick. 

It's possible to create materials that can resist even nuclear explosions. Those materials require energy pockets where thermal and kinetic energy can go. And the problem is the standing wave in those pockets. When radiation hits the material. It causes resonation in the atoms. That resonation forms the impacting waves that push atoms away. 

If there are pockets where energy can go. That makes the material more resistant to that kind of thing. The material starts to contract and that brings its structures closer to the standing waves. And that is the second critical moment. If something can conduct energy out from material and pull those standing waves away. That thing makes it possible to create a new era of material research. 

In regular nanotechnical armors, there are 2D graphene structures on top of each other. Between those structures can be DNA springs. And then. Those springs will pull impact energy into them. 

In some models, there are graphene nanotube pillars between two or more graphene layers. Those rigid structures can alternate with structures that are the DNA nano springs between layers. 

The air or some gas will travel between those layers and the energy can transfer to that gas from those pillars. The small iron bits can pull electromagnetic energy into them. Iron is the lowest energy element in the universe. And that allows EM energy to travel into iron. That allows to creation of material that will not create radar echo. And that is the new type of stealth structure.

Use virtual "perpetual motion machines" and seawater as energy sources.

   Use virtual "perpetual motion machines"  and seawater as energy sources.  The Archimedean screw can offer almost endless energy sources.  "Robert Fludd's 1618 "water screw" perpetual motion machine from a 1660 wood engraving. It is widely credited as the first attempt to describe such a device." (Wikipedia/Perpetual motion) The term "virtual perpetual motion machine" means a machine. That pulls water to the upper tank using a capillary tube. Then that water will fall through the generator or turbine wheel. The machine uses differences in pressure levels. But it looks like a "perpetual motion machine", that is impossible because of laws of thermodynamics.  The machine uses differences in pressure levels. But it looks like a " real perpetual motion machine", which is impossible because of the laws of thermodynamics.  The real perpetual motion machines don't use outside energy. And that's why they are not possible....

Will humans survive the sun's red giant stage?

"As the Sun matures into a Red Giant, the oceans will boil and Earth will become uninhabitable." (The Conversation, The sun won’t die for 5 billion years, so why do humans have only 1 billion years left on Earth?) Sooner or later, all stars use their hydrogen. And then they turn into red giants. Sun is a yellow G spectral class star that turns into a white dwarf. But before that, the sun will turn larger.  The sun turns red and that means. It starts to send more infrared radiation. This thing will turn Earth into a hellish temperature that vaporizes water from Earth.  It's possible. That Earth will also vaporize with Venus and Mercury. Some scientists say that we have only 1 billion years to move farther in the solar system. The habitable zone will go to the distance of Jupiter and Saturn, and maybe humans find a safe place in those distant moons.  It's possible that before Sun will grow too large humans make large groups of mirror satellites or large shields that sho...

Metamaterials can change their properties in an electric- or electro-optical field.

"Researchers have created a novel metamaterial that can dynamically tune its shape and properties in real-time, offering unprecedented adaptability for applications in robotics and smart materials. This development bridges the gap between current materials and the adaptability seen in nature, paving the way for the future of adaptive technologies. Credit: UNIST" (ScitechDaily, Metamaterial Magic: Scientists Develop New Material That Can Dynamically Tune Its Shape and Mechanical Properties in Real-Time) Metamaterials can change their properties in an electric- or electro-optical field.  An electro-optical activator can also be an IR state, which means. The metamorphosis in the material can thermally activate.  AI is the ultimate tool for metamaterial research. Metamaterials are nanotechnical- or quantum technical tools that can change their properties, like reflection or state from solid to liquid when the electric or optical effect hits that material. The metamaterial can cru...
