According to foreign media reports, researchers recently invented a new type of material with built-in "super power": it can bend, shape and focus sound waves, opening up new possibilities for medical imaging, personal audio and other acoustic devices. This material was developed by a group of researchers at the University of Sussex and the University of Bristol. They combined a layer of finely crafted material in the form of small bricks that can make sound waves passing through them. Phase change occurs. By placing 16 different types of bricks in a single-layer grid, researchers can use sound waves to gently float tiny polystyrene particles. Professor Sriram Subramanian, director of the interactive laboratory at the University of Sussex, explained: “We want to create acoustic devices that can operate sounds with the same ease and flexibility that LCDs and projectors can handle light.†This material is expected to be used in medical imaging and consumer audio products. Researchers have envisioned new areas of application, such as creating audio hotspots or focusing on high-intensity ultrasound to "attack" tumors in the body. Bruce Drinkwater, professor of ultrasound at Bristol University, said: “In the future, I think this technology will have many exciting applications. We are now working hard to make this metamaterial layer dynamically reconfigurable, which means that we A cheaper imaging system can be created for medical diagnosis or crack diagnosis." Dr. Gianluca Memoli of the University of Sussex responsible for the study said: "Our super material bricks can be printed out in 3D and then assembled together to form any imaginable sound field. "You can imagine a box of super material bricks. Can become DIY acoustic kit. †The results of these studies were published in the journal Nature Communications.
PCD Milling Cutter: Polycrystalline Diamond (PCD) tool is a tool made by welding a PCD composite sheet to a carbide or steel body. Since the PCD composite sheet combines the high hardness, wear resistance, low friction coefficient and strength of the single crystal diamond with the high bending strength of the tungsten carbide cemented carbide, the tungsten carbide hard alloy layer of the composite sheet provides the diamond layer. Mechanical support increases its bending strength, while the hard alloy layer is easy to weld, making it easy to make finished tools. Compared with other tool materials, polycrystalline diamond has the following characteristics: 1 extremely high hardness and wear resistance; 2 high thermal conductivity and low thermal expansion coefficient, fast heat dissipation during cutting, low cutting temperature, small thermal deformation; 3 low friction coefficient Can reduce the surface roughness of the machined surface. When processing aluminum alloy with PCD tool, the hardness of the diamond is high, the surface and metal affinity is small, and the rake face of the tool is polished into a mirror surface, which is not easy to produce built-up edge, and the dimensional stability and surface quality are good. Using PCD tools to process aluminum alloy parts of various specifications, the tool life can reach several thousand to tens of thousands, especially suitable for mass production of automobile and motorcycle parts. PCD tools are also widely used in high-speed machining of other non-ferrous metals and non-metallic materials, and are widely used in automotive, aerospace, electronics and wood processing.
