Why certain metals do not follow the effective rules
When we think of metal, we have a clear picture in our minds: we think of solid, non-breakable, conductive, and typical metallic luster objects. The behavior of classical metals, such as their electrical conductivity, can be explained by well-known and tried-and-tested physical theories.

The use of perovskite nanomaterials is expected to revolutionize next-generation electronic devices
Quantum dots are man-made nano-semiconductor materials composed of only a few thousand atoms. Due to the small number of atoms, the properties of quantum dots are between a single atom or molecule and a bulk material with a large number of atoms.

Ultra-light, pressure-resistant tensile metamaterials, deformability increased by 25 times
The catastrophic collapse of materials and structures is an inevitable result of a chain reaction of local restricted damage, from solid ceramics that produce small cracks to metal space trusses, which quickly disintegrate after small cracks are formed.

Nanodiamonds are very suitable for the needs of advanced photocathodes
In the production of high-quality electron beams, as found in the most advanced scientific equipment such as free electron lasers, ultrafast electron diffraction and imaging, and wake field accelerators, scientists regard photocathode technology as a way of converting light into electrons. method. These tools provide researchers with a way to penetrate materials, atomic structure, and behavior more deeply under actual conditions.

Engineers use light to improve 3D printing speed and accuracy
The speed of light has entered 3D printing. Engineers at Northwestern University have developed a new method that uses light to increase the speed and accuracy of 3D printing, while also combining it with a high-precision manipulator so that each layer can be moved, rotated, or expanded freely while constructing the structure.
