Femtosecond lasers can manipulate graphene.

Manipulating graphene and its shape is urgent for making that 2D carbon structure a useful tool for different purposes and components. The femtosecond lasers can make holes for different types of components in the graphene layer. The problem with 2D carbon and other 2D materials is this.

Those materials lose their abilities in 3D structure. There is a possibility to make multi-layer graphene but in that case, those layers must be separated from each other by using the DNA bites that act as nano springs or fullerene-nanotube towers.

But in that case, there must be some kind of place. Where engineers can install those auxiliary nanostructures. The thing that makes graphene interesting is that is pure carbon. That makes it possible to create mono-frequency radiation by stressing that carbon structure with electromagnetic radiation.

Researchers can use these kinds of things in communication tools and even in electromagnetic levitation tests. The idea is in those tests the system creates mono-frequency electromagnetic oscillation that turns to pressure signals which push those objects above.

If there is a hole in the graphene layer, and a laser ray will shoot through it that system can act like a thermal pump. The laser ray will pull energy out from the graphene layers. And that thing might make it possible to create new and powerful microprocessors. If a laser ray will shoot through the multi-layer graphene that thing will cool the surface, and then it can use for making the infrared signature lower.

Theoretically is a very easy thing to cover even large layers using graphene. The problem is that graphene must be separated from the layer for maximum benefit. The separated graphene layer connected with the metal layer by using the nano-springs makes the new type of system possible. The graphene can act as nano-armor and those nano-springs will receive part of the impacts that affect that 2D nanolayer.

The new bendable sensor is like straight from the SciFi movies.

"Researchers at Osaka University have developed a groundbreaking flexible optical sensor that works even when crumpled. Using carbon nanotube photodetectors and wireless Bluetooth technology, this sensor enables non-invasive analysis and holds promise for advancements in imaging, wearable technology, and soft robotics. Credit: SciTechDaily.com" (ScitechDaily, From Sci-Fi to Reality: Scientists Develop Unbreakable, Bendable Optical Sensor) The new sensor is like the net eye of bugs. But it's more accurate than any natural net eye. The system is based on flexible polymer film and nanotubes. The nanotubes let light travel through it. And then the film at the bottom of those tubes transforms that light into the image. This ultra-accurate CCD camera can see ultimate details in advanced materials. The new system can see the smallest deviation in the materials. And that thing makes it possible to improve safety on those layers. The ability to see ultra-small differences on surf

Quantum breakthrough: stable quantum entanglement at room temperature.

"Researchers have achieved quantum coherence at room temperature by embedding a light-absorbing chromophore within a metal-organic framework. This breakthrough, facilitating the maintenance of a quantum system’s state without external interference, marks a significant advancement for quantum computing and sensing technologies". (ScitechDaily, Quantum Computing Breakthrough: Stable Qubits at Room Temperature) Japanese researchers created stable quantum entanglement at room temperature. The system used a light-absorbing chromophore along with a metal-organic framework. This thing is a great breakthrough in quantum technology. The room-temperature quantum computers are the new things, that make the next revolution in quantum computing. This technology may come to markets sooner than we even think. The quantum computer is the tool, that requires advanced operating- and support systems. When the support system sees that the quantum entanglement starts to reach energy stability. I

Humans should be at the center of AI development.

"Experts advocate for human-centered AI, urging the design of technology that supports and enriches human life, rather than forcing humans to adapt to it. A new book featuring fifty experts from over twelve countries and disciplines explores practical ways to implement human-centered AI, addressing risks and proposing solutions across various contexts." (ScitechDaily, 50 Global Experts Warn: We Must Stop Technology-Driven AI) The AI is the ultimate tool for handling things that behave is predictable. Things like planets' orbiting and other mechanical things that follow certain natural laws are easy things for the AI. The AI might feel human, it can have a certain accent. And that thing is not very hard to program. It just requires the accent wordbook, and then AI can transform grammatically following text into text with a certain accent. Then the AI drives that data to the speech synthesizer. The accent mode follows the same rules as language translation programs. The ac
