Plastic waste breaks down over time into nanoplastics (<0.1 μm). Microplastics smaller than 20 μm cannot be removed in currently operating water treatment plants and must be agglomerated to a larger size and then removed. Iron (Fe) or aluminum (Al) based flocculants are used for this purpose, but they are not the ultimate solution as they remain in the water and cause severe toxicity to humans, requiring a separate treatment process. Dr. Jae-Woo Choi of the Center for Water Cycle Research at the Korea Institute of Science and Technology (KIST) has developed an eco-friendly metal-organic skeleton-based solid flocculant that can effectively aggregate nanoplastics under visible light irradiation. The research was published in Water Research. Prussian blue, a metal-organic frameworks-based substance made by adding iron (III) chloride to a potassium ferrocyanide solution, is the first synthetic pigment used to dye jeans a deep blue color and has recently been used to adsorb cesium, a radioactive element, from Japanese nuclear plant wastewater.

Anniversary of the fall of Königsberg. >Re image 2: POV, you just woke up. The anniversary was actually April 9th, but Tuesdays are so chaotic for me I didn't get around to posting. Now would be a good time for you to go and research the history of the city and it's destruction. The subject of Königsberg should not be used to stoke division, it is the tragic, shared legacy of many European peoples, may we hold hands and morn losses on all sides.

Description of Image 1: Three Prussian Officer Cadets and a junior Lieutenant gather outside of Königsberg Castle, wearing walking out dress, in April 1908. Characters are from my pre-wwi Prussian Officer Cadet drama, Moth. Their names from left to right: Vincent Odinkirk, Leon von Zelewski, Siegfried Isenstein, Gottlieb Witt. Description of Image 2: The same view of the castle, but in April 1945. Three crosses represent the deaths of the comrades in the first image. A Soviet has crawled out from a burning tank and is screaming to be put out of his misery. The Script of Moth, to which these Illustrations relate, does not continue beyond the 1920's. And so, this is likely to be my first and last piece of wwii art. The two images are 37 years and 2 world wars apart, but the castle and the surviving German officer, are meant to lend permanence to the composition. This is the destruction of his home.

Safely removing nanoplastics from water using 'Prussian blue', a pigment used to dye jeans

A new chapter of "Prussian Blue" is up!

Sorry for the long delay. This one unfortunately will likely be followed by another hiatus. I have other projects on the go, and I don't have a deep backlog after this chapter. But it felt like the right time to out this out there. So, not dead, just busy!

(Fun fact; PB as planned has gotten much larger than I initially intended it to be, and for a while I pondered splitting it into two separate chaptered fics. Thus, while I usually reserve flashback chapters for context at the beginning of a larger piece, this one instead marks an unofficial intro to "part 2" of PB, as the greater story will begin to move in a slightly different direction. Hope you enjoy!)

Various attempts at toning my cyanotype prints. Different levels of success, all interesting results. I bleach each print in a bath of baking soda and water, followed by a toning bath in a mixture of black tea and black walnut ink.
