Three dimensional tracing of a charged particle by electrostatic detection.

The Review of scientific instruments

Genc E, Mölleken A, Tarasevitch D, Utzat D, Nienhaus H, Möller R.
PMID: 31370485
Rev Sci Instrum. 2019 Jul;90(7):075115. doi: 10.1063/1.5093988.

Using a configuration of electrodes connected to charge sensitive amplifiers, the position of a charged particle in free space can be determined in all three dimensions. In our experiment, spheres with a diameter of a millimeter and a charge...

Essential oil composition of smyrnium olusatrum.


Mölleken U, Sinnwell V, Kubeczka KH.
PMID: 11711086
Phytochemistry. 1998 Nov 20;49(6):1709-1714. doi: 10.1016/s0031-9422(98)00195-2.

The essential oils obtained by hydrodistillation of green and ripe fruits, herb, flowers and roots of Smyrnium olusatrum (alexanders), have been analyzed by means of GC, GC-MS, and NMR spectroscopic methods. Roots, herb and flowers are characterized by a...

In 2018, Kīlauea Volcano experienced its largest lower East Rift Zone (LERZ) eruption and caldera collapse in at least 200 years. After collapse of the Pu'u 'Ō'ō vent on 30 April, magma propagated downrift. Eruptive fissures opened in the...

A new colorimetric method to quantify β-1,3-1,6-glucans in comparison with total β-1,3-glucans in edible mushrooms.

Food chemistry

Nitschke J, Modick H, Busch E, von Rekowski RW, Altenbach HJ, Mölleken H.
PMID: 23140737
Food Chem. 2011 Jul 15;127(2):791-6. doi: 10.1016/j.foodchem.2010.12.149. Epub 2011 Jan 09.

Mushroom β-glucans are known for their activity as biological response modifiers and anticarcinogenic agents. β-1,3-1,6 Branched glucans with a triple helix tertiary structure are recognised as the most potent ones. In the present work, a colorimetric method for β-1,3-1,6-glucan...

Dynamics of contact electrification.

Science advances

Kaponig M, Mölleken A, Nienhaus H, Möller R.
PMID: 34039611
Sci Adv. 2021 May 26;7(22). doi: 10.1126/sciadv.abg7595. Print 2021 May.

Although the electrical charging of objects brought into contact has been observed for at least 2000 years, the details of the underlying mechanism are still not yet fully understood. The present paper deals with the very basic process of...
