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.

The profits of the electrolytic aluminum industry are "rising"
The introduction of the “double carbon” policy has almost ruled out the possibility of the future release of the electrolytic aluminum supply ceiling, which has greatly eased the pressure of domestic electrolytic aluminum overcapacity.

3D printing of living cell structures with meso and microstructures
The combination of two-photon polymerization (2PP) 3D printers with innovative hydrogel-based bio-inks can directly 3D print structures containing meso-scale and micro-scale living cells. NanoUp Bio, developed by UpNano GmbH, is a 3D printer based on the NanoOne series of laser-driven two-photon polymerization. The printer can construct 12 orders of magnitude structure.

3D printing materials can replace ivory to restore old cultural relics with high precision
For centuries, ivory has often been used to make works of art. However, in order to protect the number of elephants, the ivory trade was banned internationally in 1989. Therefore, in order to restore the ivory part of the old artwork, people must resort to alternative materials such as bones, shells or plastics. However, so far there has not been a truly satisfactory solution.

3D printing of thermoplastic materials using embedded media in free form
Fused Deposition Modeling (FDM) and Direct Ink Writing (DIW) have successfully demonstrated the manufacture of thermoplastic 3D free structures involving overhanging (non-anchored) structures, but they are limited in applicable materials and printing conditions. Free-structure 3D printing requires supporting materials that can print thermoplastics in non-anchored locations.

Ultra-light bulk high-strength magnesium-lithium alloy, tensile strength up to 405MPa
Magnesium-lithium alloy is called an ultra-light alloy, with a density between 1.35 and 1.65g/cm3, and is currently the lightest metal structural material in engineering applications. The alloy has the characteristics of high specific strength and specific rigidity, strong cold and hot deformation ability, and not obvious anisotropy.

Use nanoscale 3D printing to create high-resolution light field printing
Isn’t it amazing if the printed image looks 3D? Unfortunately, traditional prints like photographs display two-dimensional (2D) images with a fixed appearance because they only contain intensity and color information. These prints cannot display 3D images because they lack direction control of the light, resulting in loss of depth information.
