Triple-Standard Hypochlorite Quantitative Array Enabled by Precise Stokes Shift Modulation in D-π-A Chemodosimeters

Click the blue text above to get more exciting content! 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)

🚀 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
