These days, smartphone manufacturers are fiercely competing, and behind the scenes, chip giants are battling it out. Qualcomm’s Snapdragon is making waves, and MediaTek is not idle either; recently, news about the Dimensity 9500 has surfaced. Regarding the manufacturing process, the Dimensity 9500 utilizes TSMC’s N3P process. This is a more advanced production line, allowing … Read more
Continuing from the previous article, this section will further introduce the types of radicals.The research team from Ohio State UniversityNagibsummarized the polarities of oxygen-centered radicals and sulfur-centered radicals.Oxygen-centered radicals are shown in Table 8. Unlike carbon-centered radicals substituted with oxygen (e.g., α– or β– alcohols), where the influence is determined by polarizability rather than electronegativity, … Read more
In industrial production, firmware flashing is a critical step to ensure the normal operation of products. However, in practical applications, due to the asynchronous nature of file writing in the Linux system, it may lead to incomplete firmware flashing, thereby affecting the normal startup and operation of the device. This article will reveal the firmware … Read more
