Many embedded designs use single-board computers (SBC) and system-on-modules (SoM) based on microprocessors and microcontrollers (for example, see “Building Low-Cost Industrial Controllers with Raspberry Pi 3”). However, many more embedded applications cannot tolerate the delays caused by software-related response times. These applications require additional performance that can only be achieved with custom hardware, and the … Read more

Synthesis of Indole: 1. Introduction Indole and its derivatives are a class of very effective pharmaceutical intermediates. Many reviews have reported on their synthesis methods. We have listed some commonly used synthesis methods for reference when synthesizing such compounds. 1 (a) G. W. Gribble, Contemp.Org. Synth., 1994, 145. (b) U. Pindur and R. Adam, J. … Read more

1. Introduction Since ancient times, people have mastered the art of producing colored decorative glass, which later revealed the presence of ultrafine particles of noble metals. In the early 20th century, Gustav Mie developed a theory that explained these intriguing color effects. It was discovered that fragmenting noble metals into nanoparticles imparts unique optical properties … Read more

The reaction of two fully substituted or multi-substituted precursors to achieve the cyclization of the benzene ring in one step results in multi-substituted benzene or heteroaromatic rings. This reaction is highly efficient and can prepare many useful multi-substituted aromatic compounds. The method of cyclization using alkenyl ketones and reactive alkynes has been well applied, leading … Read more

37 types of sensors and actuators have been widely circulated on the internet, but the number of sensor modules compatible with Arduino is certainly more than these 37 types. Given that I have accumulated some sensors and actuators, following the principle of learning through practice (it is essential to get hands-on), I am preparing to … Read more
