Recently, the Cryobiology and Medicine Research Group of the Institute of Physics and Chemistry of the Chinese Academy of Sciences reported for the first time the free shaping effect of liquid metal that can be stably presented in any shape on the surface of graphite, and achieved climbing against gravity. Movement, the research was published as a cover article in Advanced Materials.
The "endocytosis effect" in which cells engulf external particles is a common behavior in the biological world, but have you ever thought that metals can also swallow surrounding particles into the body like biological cells? Chinese scientists Through research, this magical biological-like behavior of liquid metal was discovered. Recently, this research result was published on the cover of the international authoritative journal "Advanced Science". Recently, the Cryobiology and Medicine Research Group of the Institute of Physics and Chemistry of the Chinese Academy of Sciences reported for the first time the free-shaping effect of liquid metal that can be stably presented in any shape on the surface of graphite, and achieved climbing movements against gravity. The research is presented in the form of a cover article Published in Advanced Materials.
New breakthroughs in liquid metal
Previously, metal droplets usually existed in a spherical shape in the electrolyte due to their high surface tension, and their shaping capabilities and deformation modes were relatively limited. This research realizes the free shaping of liquid metal in an open liquid environment for the first time, breaking through the original control mode of liquid metal components, and has important value in the design of amorphous flexible electronic devices, deformable intelligent machines and even advanced manufacturing.
Can be widely used in 3D printing and other fields
According to reports, liquid metal has various characteristics such as autonomous morphological changes, and can also show many magical changes under the action of electric and magnetic fields. It is widely used in 3D printing, flexible intelligent machines, vascular robots and other fields. New discoveries of biological-like behavior will further open up new areas of liquid metal research.
4 concept stocks welcome opportunities
Yunhai Metal: The company’s main products are magnesium alloys, aluminum alloys, master alloys and strontium metal. It is one of the world’s largest professional magnesium alloy manufacturers. one. The company is a new material enterprise with certain scientific and technological content. It has undertaken the development and application of key technologies for magnesium and magnesium alloys in the national science and technology plan project, and has mastered liquid metal technology.
Oriental Zirconium Industry: The company’s zirconia products are widely used in the refractory industry. Currently, products that can be directly used in refractory materials include composite zirconia, zirconium dioxide, fused zirconium, etc. Liquid metal is a new type of zirconium alloy, and zirconium is an important raw material for liquid metal. In the use of zirconium materials, especially in the use of refractory materials (especially the use of indefinite refractory materials), in order to adapt to various environments and conditions, people conduct experiments on materials such as zirconium oxide under certain conditions such as time and temperature. After effective configuration, an amorphous refractory material (often existing in liquid form) is produced. The amorphous refractory material is shaped or shaped during use according to conditions and needs through vibration, pump injection, pressure injection, spraying and other methods. Form the desired pattern for customization, repair, etc. Therefore, amorphous refractory materials made of zirconia should also be an important component of mature applications in the "liquid metal" concept.
Yian Technology: The company’s liquid metal uses die-casting technology, and Apple also uses die-casting technology. However, the company’s material formula is different from Apple’s, and both parties have their own material patents. Liquid metal has a wide range of applications, among which mobile phones, wearable consumer electronics, notebooks, etc. are currently popular areas for the application of liquid metal technology. The company will apply liquid metal technology to different products according to customer requirements. Some of the company's liquid metal products are already being supplied in small batches, but customer information has not been made public due to the need to keep it confidential.
Antai Technology: The company was restructured from the Iron and Steel Research Institute and has strong technical strength. Its main products include three categories: super-hard and difficult-to-form material products, metal functional materials and fine metal products. Among them, the metal functional materials segment includes amorphous materials and rare earth permanent magnets; the company is one of the two companies in the world that can produce amorphous strips. The National Amorphous Microcrystalline Alloy Engineering Technology Research Center of Antai Technology Amorphous Products Company has Started a 10,000-ton amorphous strip and product project. After the completion of the second phase of the project in 2010, it has achieved an annual output of 40,000 tons of iron-based amorphous strip. If there is still room for downstream demand, we will continue to expand production capacity to 70,000-100,000 tons/year. The company plans to rank second in the world in production capacity of iron-based strips in the amorphous industry, rank first in the world in production capacity of nanocrystalline strips and amorphous magnetic powder cores, and ultimately achieve sales revenue of 1 billion yuan.
