Bioinorganic #Chemsky Group of Lena Daumann @HHU.de PI tweeting. We love iron, rare earth elements, enzymes and bacteria!🧫 🧪 #fblockrocks www.bioac.hhu.de/

Picture of a floor with orbital models next to a Lego train track and some other toys
View of an iron sulfur cluster with an additional metal ion. Copper as copper-colored sphere, Iron as silver sphere, and sulfur as yellow spheres. Protein backbone indicated as golden tubes
Pride Flag made from snippets of lab photos: red crystals or Cobalt complex, orange liquid in round bottom flask, yellow tubes, green chunky Crystals of iron(IV) complex, blue agar plates from CAS assay for siderophores, and purple star shaped crystals. Black and white crystals, numbers from bioinformatics pipeline, fluorescent baby blue substance, pink holmium oxide, clear reagent tubes, yellow bubbly liquid, purple ring with crystals. Right corner it reads @Daumannlab
Video showing different chemistry experiments and snippets form lab tours at chemistry and biochemistry labs
Photo of a lab tour. Kids are wearing lab coats and glasses and Sophie is showing agar plates

Picture collage. In the center a QR code, that leads to a Webseite also linked in the text. In the right a fine hood with bright red fire is seen, below a periodic table. On the left an agar plat with bacteria growing in the form of a mouse. Upper left photo of two people in labcoats playing with liquid nitrogen.

A screen shot form the German train app, final destination is Düsseldorf with 1,5h delay. Multiple reasons/issues for the delay are given: late due to delay from before, technical difficulties with train, incidence with needed police, train operation without segment 8 and missing Barriere free toilet. Also exceptionally high demand is communicated.
Two group pictures, taken 6 years apart. Some persons are found on both fotos. In the middle there is a greenish copper statue, in the back a glass front of a Building. The person in the middle makes a goofy face and gesture, on the new picture below one of the persons is wearing a traditional German PhD hat with pictures and decorations on it.
Periodic table, element samples and magnets on a table. In the Back boxes with safety glasses
Holzbank. Darauf liegen eine Banane, Reiswaffeln, Flasche mit Wasser und zwei ziplock Tüten mit Kirschen, Aprikosen und zwei Basilikumblättern. Rechts und links davon kann man Beine von einem großen und einen kleinen Menschen erkennen.
Two people in front of a botanical garden backdrop. Different exotic flowers and trees are in the background.
A small creek is shown, on the side of the viewer 4 sheep are sitting underneath a flowering tree. The sun is breaking through the crown of the tree generating a dreamy scene
Photo of Sophie a young female scientist, next to purple and blue design. It reads Cas Future leaders congratulations Sophie gutenthaler-Tietze Heinrich Heine University
Brown and white Jack Russel doggo with a green scarf with Daumann gang written on it. He looks adorable. Photo and doggo by Johanna Grossmann
Reaction network arising from the La3+-catalyzed reaction of glyoxylate and pyruvate, including non-detected intermediates with the most probable routes represented by arrows requiring either one or both of the reactants are shown. Some can be deteced by GC-MS others only by NMR, some by both.
Pot with flames form the disposal of LDA.
A pot is shown where someone with blue gloves discards a black substance from a spatula, that ignites upon exposure to air
Toddler experimenting with red cabbage juice. There is a grey baking tray and a glass of pink red cabbage juice, a 24 well plate filled with pink liquid and some lemons. Toddler is holding a Plastik Pasteur Pipette
A large periodic table is shown hanging in a lecture hall. Below is a Fume hood, fire extinguisher, and glimpses of the wooden wall behind and below can be seen as well as a part of a chalkboard. The periodic table is not correct (in addition to missing some elements). All the mistakes will be revealed in a reply to this post
A piece of peculiar glassware. Looks like en erlenmeyer with a screw top and five glass screws connectors on each side. Has a bit of the shape of a Christmas tree.
A Bar chart showing optical densities of bacterial cultures in the presence of differnet lanthanides. Promethium is included and fits well within its expected spot in the lanthanide series. In the right upper corner a comic of a cultivation flask with bacteria is shown.
A table top with lots of colorful petri dishes. Some are blue some show bacterial colonies surrounded by yellow or orange hues against a blue Cas media background. Photo credit: Dr. Carl-Eric Wegner
Lena Daumann in front of the Ytterby gruva plaque. Mostly grey rock with some patches of green and ferns are shown
Hand holding up a tiny green lab jack.
Toddler sitting at a table with toys and books in the front of chairs of a big lecture hall.
Plate with some thin milk chocolate that has a fine grating on the surface leading to rainbows shimmering under a light source
A Lego HPLC and QTOF with two Lego scientists is shown in the foreground. A grey cat is sitting on top of the QTOF. The Lego scientists hold Lego pipettes, Petri dish and tools. In the far back a bookshelf can be made out.
You can see three beakers filled with some liquid. The liquids change colors from orange to blue and back
The two chelators are drawn as comics as crabs binding to Fe or Ln ions. Those with MLL sink to the bottom as the complexes precipitate.
Sophie as Lego Figure in front of our lego HPLP QTOF Agilent system. Her cat Rosie (honoray lab member) is also shown. Along with Oli, our student assistant.
Two Lego scientists (Mikey and Tri) shown in front of a Lego Fumehood and Lego HPLC holding lego flasks
Lego Figure of a scientist (Sophie) with long brown hair holing a lego pipette sitting in front of a lego microbiology lab bench.
Two chelators are shown. The ventraö citric acid mojety is highlighted in yellow, the two chelator arms bear either a phenol unit (for MLL) or a 2,3 dihydroxy benzene unit (for RPB B)
Crystals are crushed between two slides of glass, and blue sparks can be seen from triboluminescence
Red wine bottle by educated guess, showing chemical reactions in white on black background
