cenchempics: Separate the rainbow Roberta R. Rodrigues spent the day staring down this multicolor silica gel column as she used it to purify a dye she’d made. Rodrigues—who was a PhD student in the lab of Jared Delcamp at the University of Mississippi when she took this photo and is now a postdoc at Pacific Northwest National Laboratory—was working on finding new squaraine dyes. These molecules, named after their square-shaped core structure, can be stunningly colorful, as is clear from the bright bands of this column. Rodrigues was using squaraines for applications in dye-sensitized solar cells, which create electricity from interactions between sunlight, dyes, and electrodes.— Manny I.
