Future and Emerging Technologies

Not only photovoltaics, but also the lightest and most abundant No. 1 element in the universe-hydrogen, may be the hope of global new energy in the future. The latest research report released by Bank of America Merrill Lynch Haim Israel stated that hydrogen can meet global energy demand, provide fuel for cars, heat homes, and help cope with climate change. It is expected that by 2050, the market share will soar 6 times, resulting in 2.5 Trillion dollars in direct revenue, indirect infrastructure market potential is as high as 11 trillion dollars. Bank of America Merrill Lynch believes that hydrogen technology has existed for decades, but it has not yet reached the critical point of mainstream use. The future integration of economic, technological, and environmental development will change this situation: 1. The cost of electrolyzers and renewable energy used to produce green hydrogen has decreased According to data from Bank of America Merrill Lynch, the cost of electrolyzers and renew...

Not long ago, the MicroLED display, which had only existed in display cabinets and PPT, finally entered the formal mass production stage. At the beginning of its appearance, the MicroLED technology was considered to be the first display technology without size limitation in history, and it has become the recognized future development direction of display screens, so it is strongly sought after by manufacturers in the entire display industry chain. The basic characteristics of Micr OLED technology are excellent: this reality technology has a wide color gamut, high brightness, low power consumption, high stability, long life, wide viewing angle, high dynamic range, high contrast, high refresh rate, transparency, and support Features such as seam connection and integrated internal sensors. Although these characteristics are realized on LCD, OLED and QD panels respectively, MicroLED technology can realize these technical characteristics at one time, and there are almost no obvious shortcom...

According to foreign media reports, as long as the oxygen tank can keep astronauts breathing for a long time, they can survive in the space suit. Currently, the two oxygen tanks and emergency oxygen replenishment system in the extravehicular space suit (EMU) commonly used by astronauts can provide 6.5-8 hours of oxygen supply. How long can an astronaut survive in a spacesuit? Currently, the two oxygen tanks and emergency oxygen replenishment system in the extravehicular space suit (EMU) commonly used by astronauts can provide 6.5-8 hours of oxygen supply. The human mind is bewildered by the intricacies and mystery of the universe, and is committed to uncovering the mysteries, from believing in the theory of flat earth centered on the "geocentric theory" to the shadows of black holes photographed today, to fantasy space elevators and witnessing business. The company executes manned orbital flights. With the development of human technology, we have made great progress in the fi...

The Ryzen 5000 series released by AMD two days ago upgraded the 7nm Zen3 architecture. This time not only the multi-core performance has advantages, but the single-core performance is also greatly improved. After all, the IPC has risen by 19%. Compared with the previous generation Ryzen 3000 series, the product line of the Ryzen 5000 series has been simplified this time. There are currently only four models, as follows: Ryzen 9 5950X: Dual CCD, 16 cores and 32 threads, 8MB L2 cache, 64MB L3 cache, base frequency 3.4GHz, maximum acceleration frequency from 4.7GHz to 4.9GHz, thermal design power consumption maintained 105W, priced at $799 . Ryzen 9 5900X: dual CCD, 12 cores and 24 threads, 6MB L2 cache, 64MB L3 cache (naturally changed), the base frequency is lowered from 3.8GHz to 3.7GHz, but the maximum acceleration frequency is increased from 4.6GHz to 4.8 GHz, the thermal design power consumption remains 105W. If you compare the Ryzen 9 3900XT, the base frequency is lowered by 100MHz...

  As the temperature in the northern hemisphere turns cooler, the number of new cases in a single day in many European countries continues to record high. In the United States, the number of new cases in a single day has been hovering at a high level. According to reports from the World Wide Web citing foreign media, a new Australian study shows that the new coronavirus can survive on banknotes, glass and other surfaces for nearly a month. Scientists from the Australian Centers for Disease Prevention said that the new coronavirus is very "sturdy" and can survive 28 days on smooth surfaces at room temperature or 20 degrees Celsius, such as mobile phone screens and plastic banknotes. In contrast, the common flu virus has a life span of 17 days. The study highlighted the risk of spreading the virus from banknotes, touch screen devices, handles and handrails. This study also found that the new coronavirus survives longer in cooler weather, so the virus may be more difficult to co...
