According to recent news from the official website of the University of Alberta, Canada, scientists at the school have perfected related technologies and developed a solid-state memory with the highest storage density to date. Its storage capacity has increased by 1,000 times compared with current computer storage devices.
Roshen Karl, the head of the latest research and PhD student of the school ’s physics department, said: "Fundamentally speaking, with the new memory, you can store all 45 million songs on iTunes on a 25-cent coin-sized surface.5 Years ago, we thought this was impossible. "
The research team used the technology they developed to manufacture atomic-level circuits. This technology can quickly remove or replace a single hydrogen atom, which allows the memory to be rewritten, so it can provide a more efficient type of solid-state hard disk for the computer. .
To demonstrate the new memory, the researchers encoded the entire alphabet at a density of 138 terabytes per square inch, which is equivalent to writing 350,000 letters on a grain of rice.
Akar emphasized that the previous atomic-scale computing storage device can only be stable under extremely low temperature conditions, and the new memory can also work at room temperature. Perhaps the most direct application area for this technology is data archiving. Next, they will further improve the reading and writing speed so that they can show their talents in more fields.
Robert Volko, another head of the latest research and professor of physics at the school, is very proficient in the field of atomic physics. He perfected the technology at the nano tip, allowing scientists to manipulate individual atoms on silicon chips. This technology has now reached an inflection point, and researchers are working to commercialize atomic-level manufacturing that can be applied to all technical fields. (Reporter Liu Xia)
The stainless steel threaded rod is a metal part used for fixing, fastening and connecting. It usually consists of a threaded head, a threaded part and a cam tooth part. It has high strength and corrosion resistance, and is also called a flange bolt. Stainless steel threaded rods are used in a variety of architectural structures, including machinery, ships and aircraft, as well as equipment such as spacecraft and marine engines. They have the advantages of impact resistance, corrosion resistance, heat resistance and wear resistance, can better resist harsh environment and friction, and have a long service life and stability.
Thread rods are cylindrical metal rods with external threading along their entire length. They are commonly made from materials such as steel, stainless steel, or brass. The external threading on the rods allows them to be fastened securely into corresponding threaded holes or nuts. Thread rods are typically used in various applications where a strong and reliable connection is required, such as in construction, manufacturing, or mechanical engineering. They are available in different diameters, lengths, and thread sizes to suit specific needs. Thread rods are often used in conjunction with nuts, washers, or other fasteners to create a secure and stable connection.
