The new nanomaterials are stronger and more durable than ever before.

Nanotechnology opens the door to new lightweight materials. Those materials are lightweight and stronger than anything before. Some of the latest materials are based on ring-shaped spring structures. That material includes two entangled material lines. 

The material acts like spring beds. When impact comes it pushes the "8" shaped structures sideways. That transfers the energy to the molecules around it. The two-material structures make it possible. That impact energy cannot affect materials. As an entirety. The material becomes more durable when the number of horizontal material layers with different molecular structures rises. 

The image above this text shows how the structure can flex when something presses it. When this structure faces pressure the molecule chains that base is in carbon will flex and that ability shares the impact energy with other molecules. If we think that the material forms lattice layers that thing means that material shares energy horizontally. The important thing is that there should not be reflection from other molecules. That denies the form of the standing waves. 

Material can stand high energy levels if it can conduct that energy somewhere. Those lightweight materials have many uses from satellites to armored vehicles and wearable body armor.

The new thing that nanotechnology allows is the ultimate heat resistance. The traditional way to protect the layer against heat is to conduct it away. There can be pillars in the airflow that conduct heat from the layer to that airflow. But this thing doesn't remove the horizontal heat effect. This is why heat destroys molecules. 

When heat impacts a snowflake that structure melts because the snowflake cannot put that energy anywhere. That forms standing waves that destroy the structure. One of the answers is to make the material that edge is colder or at a lower energy level than the middle of it. That conducts energy out from the center.  When energy travels in one direction it will not make those standing waves. 

The magnets can be the solution for the materials that turn stronger when they face pressure. In still theoretica nanomaterials there is some kind of magnetic structure-nanocrystal compounds. When something presses those nano-crystals they form a piezo-electric phenomenon that makes the magnetic fields in magnetic structures stronger. When that phenomenon is connected to alter magnetism the new form of magnetism that means the materials is antimagnetic from outside. The magnetic structures are inside that material. 

The Quanta magazine tells about an interesting phenomenon. "Researchers cooked up a striking exception. In a string of results over the past few years, researchers have shown that an idealized substance resembling two intermingled magnets can — in theory — maintain an orderly pattern no matter how hot it gets. The discovery might influence cosmology or affect the quest to bring quantum phenomena to room temperature." (Quanta, Heat Destroys All Order. Except for in This One Special Case.)

There is a theoretical possibility that the intermingled magnets can keep their form without depending on the temperature. That phenomenon is one of the newest and most interesting things in material sciences. The idea is that the magnetic particles can bind to each other without decreasing temperature. In ideal cases, there are magnetic particles whose magnetic force rises when temperature rises. That makes the material stronger when its temperature rises.
