Mechanism of the far-infrared absorption of carbon-nanotube films.

Physical review letters

Kampfrath T, von Volkmann K, Aguirre CM, Desjardins P, Martel R, Krenz M, Frischkorn C, Wolf M, Perfetti L.
PMID: 19437671
Phys Rev Lett. 2008 Dec 31;101(26):267403. doi: 10.1103/PhysRevLett.101.267403.

The far-infrared conductivity of single-wall carbon-nanotube ensembles is dominated by a broad absorption peak around 4 THz whose origin is still debated. We observe an overall depletion of this peak when the nanotubes are excited by a short visible...

Gastrointestinal transit and contractility in diabetic constipation: A wireless motility capsule study on diabetes patients and healthy controls.

United European gastroenterology journal

Sangnes DA, Lundervold K, Bekkelund M, von Volkmann HL, Berentsen B, Gilja OH, Dimcevski G, Søfteland E.
PMID: 34687494
United European Gastroenterol J. 2021 Dec;9(10):1168-1177. doi: 10.1002/ueg2.12169. Epub 2021 Oct 23.

BACKGROUND: Diabetic constipation is traditionally attributed to slow colonic transit, despite limited evidence. More than half of patients find treatment unsatisfactory. To improve treatment, there is a need for better diagnostic understanding of the condition.OBJECTIVE: In this wireless motility...

Time-of-flight photoelectron momentum microscopy with 80-500 MHz photon sources: electron-optical pulse picker or bandpass pre-filter.

Journal of synchrotron radiation

Schönhense G, Medjanik K, Fedchenko O, Zymaková A, Chernov S, Kutnyakhov D, Vasilyev D, Babenkov S, Elmers HJ, Baumgärtel P, Goslawski P, Öhrwall G, Grunske T, Kauerhof T, von Volkmann K, Kallmayer M, Ellguth M, Oelsner A.
PMID: 34738944
J Synchrotron Radiat. 2021 Nov 01;28:1891-1908. doi: 10.1107/S1600577521010511. Epub 2021 Nov 03.

The small time gaps of synchrotron radiation in conventional multi-bunch mode (100-500 MHz) or laser-based sources with high pulse rate (∼80 MHz) are prohibitive for time-of-flight (ToF) based photoelectron spectroscopy. Detectors with time resolution in the 100 ps range...

Comparison of pre-analytical conditions for quantification of serotonin in platelet-poor plasma.

Practical laboratory medicine

Von Volkmann HL, Brønstad I, Fiskerstrand T, Gudbrandsen OA.
PMID: 31649988
Pract Lab Med. 2019 Sep 19;17:e00136. doi: 10.1016/j.plabm.2019.e00136. eCollection 2019 Nov.

BACKGROUND: Reported concentrations of serotonin in platelet-poor plasma (PPP) in healthy subjects vary widely due to different pre-analytical procedures.AIM: To examine how different pre-analytical conditions affect the measured concentration of serotonin in PPP.METHOD: Six pre-analytical protocols were compared for...
