Man kann zu wenig tun, nie aber zuviel!

Wir sind nicht nur verantwortlich für das, was wir tun, sondern auch für das, was wir nicht tun.
^{Laotse oder Moliere...}

Mensch sein heißt verantwortlich sein.
^{Antoine de Saint-Exupéry}

Wenn wir nicht länger in der Lage sind, eine Situation zu ändern, sind wir gefordert, uns selbst zu ändern.

The better you see, the more you know

Learn how hyphenated HPTLC can make a difference, and join our next hybrid course on effect-directed analysis taking place in March 2023.

The chemical industry including analytical techniques has no choice but to become more sustainable. HPTLC is proven to be environmentally friendly, as evident in the latest greenness assessment by analytical Eco-Scale. The straightforward non-targeted effect-directed screening improves the knowledge on important bioactive components in complex samples, including unknown unknowns, contaminants and non-intentially added substances. Not every detected unknown compound can be elucidated in its structure, but a decision on first priority compounds can thus be made. A fast and generic 8D hyphenation strategy clearly shows the gain in information. For example, it visualized that plant-based food contains powerful effective compounds which contribute to our homeostasis.

The plant extracts shown below were examined with the latest planar multiplex assay for detection of estrogen- or androgen-like substances: Agonists are detectable as a (methylumbelliferone) blue fluorescence zone, whereas antagonists show fluorescence signal reduction on the first agonist strip (fluoresces only after the assay) and false-positive antagonists also on the second end product strip. Synergists enhance the blue fluorescence on the agonist strip.

Awarded with the Poster Prize

At the Curious2022 Future Insight™ conference in Darmstadt, 12-14.07.2022, our poster was awarded with the poster prize - congratulations to all coauthors (A. Ziltener, S. Geyer, A. Mehl, T. Schreiner, T. Kamel, J. Tersteegen, F. Brümmer)!! It was presented as ePoster on TV screens in a special format of three slides: Dolphins' beauty secrets

HPTLC 2022 Symposium in Ljubljana, Slovenia

The Scientific Commitee welcomes two new members: Dr. habil. Stefan Böhmdorfer from Austria (3rd from left) and Dr. habil. Claudia Oellig from Germany (4th from left). Happy to see the excellent next generation! And there are moooreeee....

Maja Bensa did a great job arranging the ChromART Competition. She is so tough and great! Unsurprisingly, her mother is Dr. Irena Vovk, who did a great job together with Dr. Vesna Glavnik organizing the symposium with their team:

Hanna Nikolaichuk from Ukraine awarded with the Dr. Heinz Hauck Young Scientist Prize for the Best Oral Presentation

Ecesu Sezen from Turkey awarded with the Elke Hahn-Deinstrop Young Scientist Poster Prize

Dr. Rudolf Kaiser Poster Award granted by Dr. Olga Kaiser to Dr. Karem Henriquez-Aedo from Chile

Silver poster prize awarded to Dr. Ágnes Móricz from Hungary

Bronze poster prize awarded to Dr. Claudia Oellig from Germany

May be next sympoisum in Budapest organized by Dr. Ágnes Móricz and her team?

Guest speaker

We had the honor to welcome Prof. Dr. Rob Verpoorte at JLU Giessen in June!
He presented two guest lectures:

• How to write a world-class scientific paper
• Natural deep eutectic solvents: “You see it, when you understand it”

Here the recording of the paper writing lecture:

Guests on earth

We honor Prof. Dr. Anton Dieter Hammel who passed away on March 12, 2022, aged 85. He was a recognized expert in the international bread and baked goods industry. First in the Central German Simonsbrot factory, and since 1994 as co-owner and managing director of Lieken-Batscheider Mühlen- und Backbetriebe, he received the Federal Cross of Merit on Ribbon in 1990, is the owner of numerous patents and became honorary professor at the JLU Giessen. On October 26, 1988, Professor Dr. Anton Dieter Hammel held his first lecture, initially in the graduate course in cereal technology. Since the modularization of the degree programs, he read the module MP-005 Food Technology, most recently jointly with me for 8 years. He has been warmly associated with food science ever since. His sensory exercises were particularly popular with the students. He also gladly told of his professional practice, where especially his work at the DLG testing and the development of the astronaut bread with patenting should be highlighted. After his 30th anniversary as a lecturer in December 2018, he retired from academial lecturing. He was an amazing personality with pointed remarks & allusions, all spiced with humor. He will remain in our hearts forever.

Grundsteinlegung für unsere Forschung

150. Geburtstag von Michail Semjonowitsch Zwet geboren am 19. Mai 1872 - wir werden gedenken!
Er ist der Erfinder der Chromatographie. 1903 präsentierte er der damaligen Fachwelt seine Befunde zu Adsorptionserscheinungen: Blattfarbstoffe mit Petroether an Calciumcarbonatsäule! "Ihm war es gegeben, die Chromatographie zu entdecken, die die Moleküle trennt und die Menschen verbindet!" so steht es auf seinem Grabstein.

After 6 years of work on this basic paper on botanicals (further reading), we have finally done it! Translation is in process.

Wir neigen viel zu sehr dazu, Dingen, die das Ergebnis vieler Ursachen sind, einer einzigen zuzuschreiben.
^{Justus von Liebig}

Nature is perhaps too complex for artificial intelligence and human understanding. If nature is so sophisticated, why are we destroying it?
