U.S. is developing a series of methods for manufacturing new materials
 |
The study found that the characteristics of the material at the nano level (close to the atomic scale) are difficult to retain and develop. In fact, on the near-atomic scale, the unique and potential electrical, optical, and stretchable properties of materials tend to disappear after they have been fabricated into materials and systems on the order of millimeters or centimeters using conventional processes. How to retain the extremely valuable material properties possessed by the atomic scale is a difficult problem in the current material science field.
The Department of Defense Science (DSO), the most important organization of the US Department of Defense Advanced Research Projects Agency (DARPA), recently announced that it has set up a series of research projects with a view to achieving the goal of maintaining the material properties at the atomic scale as soon as possible. . From the following specific research projects, we can see the direction of the future change of new materials research.
Atomic to Product (A2P)
The goal of the "atom-to-product" research project is to develop an assembly method that enables the manufacture of large-scale materials, components, and systems that preserve the performance of nanoscale materials.
Currently, scientists mostly use different “mixed, heated, and combined†methods when developing new materials. DARPA project manager Mein said: “Now we are using a completely different approach, starting with individual atoms and assembling them directly. Into nanostructures, and then assemble this nanostructure into larger microdevices.†He pointed out that the “atom-to-product†project group has a new method of controlling nanoscale assembly that can be produced very quickly and economically valuable. Advanced micro devices.
Controllable Microstructured Architecture Material (MCMA)
DARPA is also investigating another method to create new materials with special features called "materials with controllable microstructures." The MCMA is seeking ways to control the microstructure of the material to improve structural performance and to achieve functions that are traditionally difficult to obtain simultaneously in a single substance, such as the strength of steel and the weight of plastic.
Material Conversion (MATRIX)
One potential benefit of controlling the internal nanostructures of materials is that they can be used to enable catalytic reactions or energy conversions on their own, and to effectively convert them into devices. This is also the ultimate goal of the DSO “Material Conversion†project. Like A2P, it is the development of a new material for conversion that enables energy conversion from one form to another in order to achieve useful functions of new materials at the device and system level. Material conversion is very important for the improvement of military capabilities of land, sea, air and space, but at present many of the functions of materials in the laboratory are difficult to play in reality. The goal of MATRIX is to transform the functions in the laboratory as soon as possible in the real world.
MATRIX is currently concentrating on researchers in the fields of modeling, design, and manufacturing. It is developing a unified research and development method and hopes to build a bridge between materials and devices. The research results will improve the efficiency of energy harvesting, heat treatment and refrigeration equipment, and make sensors, driving devices and radio equipment more efficient.
Extended Solids (XSolids)
The "Extended Solids" project is dedicated to the development of special materials, which are usually manufactured and exist only in ultra-high pressure (millions of atmosphere) conditions. As the physical, mechanical, and functional properties of many materials change drastically under different pressures, the discovery and manufacture of new materials are mostly based on high-temperature applications, while the development of high-pressure chemistry (or pressure chemistry) is a new material. Discovery and manufacturing opened a new era.
DARPA established multidisciplinary laboratories 50 years ago to bring together experts in devices and materials related fields. Tompkins, head of the DSO, believes that these research projects reflect a fundamental change in the future direction of new materials research, namely the transformation from bulk-process to structural materials, which indicates the development of new “designer times†( Designer age).
