The new metamaterials are a new type of stealth material.



In nanotechnology, reflection denying makes it possible to create layers. that don't cause energy impulses to molecules and structures in the reaction chamber. The same technology makes it possible to make layers invisible to radar, infrared, and human eyes. Infrared stealth requires that the aircraft's shell will be cooled. Low-temperature layers decrease the infrared signature of the material. 

The reflection is the thing that makes objects visible. And if the system can transfer reflecting radiation away from the observer. That makes it impossible to see the object. 

In some ideas two-layer structure allows air flow to travel inside it. That decreases the temperature of the shell. There are also plans to use plasma or neutral gas systems. That blows gas or ions over the aircraft's outer shell. That should make the aircraft slippery and deny the airflow straight effect to the aircraft shell. In some other ways, the aircraft's shell is equipped with nano-rolls that decrease the airflow's energy transfer to the aircraft's shell. The soft forms of stealth aircraft also decrease their friction. 

The new metamaterials with triangular 2D molecule structures can transfer thermal energy out from the layer. The 2D triangular structure that is between two layers of 2D materials can transfer thermal energy to air. That flows between those layers. That technology makes objects invisible to IR sensors. But it also makes it possible to create new, ultra-fast aircraft. Friction is the problem with high-speed aircraft.

Another thing is that two-layer semiconductor structures can create a stable positive electron-hole series into the lower layer. And then, the electricity that radar transfers to the outer layer travels to the inside layer. That can make it possible to create structures that are invisible to radars. Things like laser rays that hit the lower layer can make those stable holes that conduct radio- and electric impulses in desired directions.  

Denying reflection can happen by transferring energy out from the observer. Or the system can tie it inside it. There are invisible energy states in molecules. It's possible. The system can transport energy into those energy pockets. The thing that can make the material invisible to the observer is that there is some kind of hovering energy field. That changes reflecting radiation's wavelength. These kinds of systems can be the key to future stealth systems.

New AI-based operating systems revolutionize drone technology.

"University of Missouri researchers are advancing drone autonomy using AI, focusing on navigation and environmental interaction without GPS reliance. Credit: SciTechDaily.com" (ScitechDaily, AI Unleashed: Revolutionizing Autonomous Drone Navigation) The GPS is an effective navigation system. But the problem is, how to operate that system when somebody jams it? The GPS is a problematic system. Its signal is quite easy to cut. And otherwise, if the enemy gets the GPS systems in their hands, they can get GPS frequencies. That helps to make the jammer algorithms against those drones. The simple GPS is a very vulnerable thing.  Done swarms are effective tools when researchers want to control large areas. The drone swarm's power base is in a non-centralized calculation methodology. In that model, drones share their CPU power with other swarm members. This structure allows us to drive complicated AI-based solutions. And in drone swarms, the swarm operates as an entirety. That ca...

Hydrogen is one of the most promising aircraft fuels.

Aircraft can use hydrogen in fuel cells. Fuel cells can give electricity to the electric engines that rotate propellers. Or they can give electricity to electric jet engines. In electric jet engines. Electric arcs heat air, and the expansion of air or some propellant pushes aircraft forward. Or, the aircraft can use hydrogen in its turbines or some more exotic engines like ramjets. Aircraft companies like Airbus and some other aircraft manufacturers test hydrogen as the turbine fuel.  Hydrogen is one of the most interesting fuels for next-generation aircraft that travel faster than ever. Hydrogen fuel is the key element in the new scramjet and ramjet-driven aircraft. Futuristic hypersonic systems can reach speeds over Mach 20.  Today the safe top speed of those aircraft that use air-breathe hypersonic aircraft is about Mach 5-6.   Hydrogen is easy to get, and the way to produce hydrogen determines how ecological that fuel can be. The electrolytic systems require elec...

The neuroscientists get a new tool, the 1400 terabyte model of human brains.

"Six layers of excitatory neurons color-coded by depth. Credit: Google Research and Lichtman Lab" (SciteechDaily, Harvard and Google Neuroscience Breakthrough: Intricately Detailed 1,400 Terabyte 3D Brain Map) Harvard and Google created the first comprehensive model of human brains. The new computer model consists of 1400 terabytes of data. That thing would be the model. That consists comprehensive dataset about axons and their connections. And that model is the path to the new models or the human brain's digital twins.  The digital twin of human brains can mean the AI-based digital model. That consists of data about the blood vessels and neural connections. However, the more advanced models can simulate electric and chemical interactions in the human brain.  This project was impossible without AI. That can collect the dataset for that model. The human brain is one of the most complicated structures and interactions between neurotransmitters, axons, and the electrochemica...
