Picture: Haematite by Gemma Anderson.
I found a drawing of [haematoma] of the brain by R.Hooper which reminded me so much of a particular haematite specimen I had seen at UCL and so I decided to recreate the drawing of the brain(a zoological specimen) with haematite (a mineral specimen) because of their anatomical resemblances to one another.
Empa scientists mimic photosynthesis in photo-electrochemical cells using haematite and phycocyanin (a light-harvesting pigment used by blue-green algae, aka Lina Blue food coloring) electrodes. (Source)
There seems to be a delicate balance where organic molecules not only survive harsh photocatalytic conditions, but even convey an additional benefit to ceramic photocatalysts: They double the photocurrent. This is a big step forward.
