May 1st 2025 (Image by Cindy Li)Robots are indeed helping American manufacturing by replacing human labor. In 2024, the average cost of wages and benefits for a manufacturing worker in the U.S. is approximately $45 per hour; whereas the total lifecycle cost of a robotic arm in a factory is about $10 per hour, and … Read more
When you see a programmer’s hands flying over the keyboard, it is often not about coding, but rather likely a heated discussion with the product manager about requirements; another possibility is a verbal sparring match with the testers; there’s also a 10% chance they are writing on forums to pass the time; and a 1% … Read more
Perovskite tandem solar cells (TSCs) have become a research hotspot in the photovoltaic field due to their high theoretical efficiency (>40%) and low-cost fabrication processes. However, wide-bandgap (WBG) perovskites face significant challenges such as crystallization inhomogeneity, phase separation, and high defect density caused by bromine doping, which severely limit the efficiency and stability of large-area … Read more
Problem Addressed: Traditional optical levitation systems face challenges such as large optical component sizes and low integration when achieving high-frequency rotational control of nanoparticles in a vacuum. Additionally, there is a lack of efficient means to control the translational and rotational motion patterns of nanoparticles, limiting their application in ultra-precision measurement and fundamental physics research. … Read more
Research Background Perovskite materials have become an ideal choice for next-generation photovoltaic materials due to their excellent optoelectronic properties and low-cost manufacturing processes. They are widely used in solar cells, photodetectors, and light-emitting devices. Compared to traditional silicon-based materials, perovskite materials offer significant advantages such as higher light absorption efficiency, broader spectral response, and lower … Read more

Abstract The rational design of D-π-A type chemosensors with significant Stokes shift is crucial for enhancing the visualization of optical sensing signals. Here, three D-π-A type fluorescent chemosensors were synthesized using 2-(3-cyano-4,5,5-trimethylfuran-2(5H)-yl)malononitrile (TCF) as the electron-withdrawing group by precisely adjusting the electron-donating strength. By reducing … Read more
🚀 Comprehensive Guide to Selecting SerDes Chips Based on Screen/Camera Resolution (Formula Derivation + Practical Cases) 1. Why Select SerDes Based on Resolution? First, let’s briefly discuss the background: SerDes (Serializer/Deserializer) essentially compresses/decompresses data bandwidth, transmitting high-speed data (screen images, camera video) to another location. The higher the resolution, the higher the refresh rate/frame rate, … Read more
01 Introduction The dual color LED sensor is an LED that can display two colors. It has three states: off; color 1 on; color 2 on. Depending on the color combinations, dual color LEDs can be red-blue, yellow-blue, red-green, etc. Dual color LEDs are commonly used as status indicator lights, such as indicating whether an … Read more
