A research team at POSTECH (Pohang University of Science and Technology) has successfully developed a super-photostable organic dye after two years of dedicated research. Their study is published in ...

As it turns out, the ever-useful 555 timer chip does the job admirably. It’s a simple enough circuit, the threshold pin is pulled high so the output goes high, and the PWM drive from an Arduino ...

[FightCube] wrote in recommending a very helpful piece of circuit simulation software for those of you still constructing entries for the 555 design contest. LTSpiceIV, available from Linear ...

Single-molecule imaging, a technique that uses fluorescent markers to track proteins with precision, plays a crucial role in ...

In collaboration with Professor Young-Tae Chang's team, they identified its structure using mass spectrometry and nuclear magnetic resonance analysis, naming it Phoenix Fluor 555 (PF555).
