Electrochemistry in Micro- and Nanochannels Controlled by Streaming Potentials [PDF]

open access: yesThe Journal of Physical Chemistry C, 2020
Fluid and charge transport in micro- and nanoscale fluidic systems are intrinsically coupled via electrokinetic phenomena. While electroosmotic flows and streaming potentials are well understood for externally imposed stimuli, charge injection at electrodes localized inside fluidic systems via electrochemical processes remains to a large degree ...

An unexpected alternative viologen electron mediator site in tungsten‐containing formate dehydrogenase

open access: yesFEBS Letters, EarlyView.
An unexpected alternative interaction site for ethyl viologen was identified in formate dehydrogenase 1 from Methylorubrum extorquens. Combined mutagenesis, kinetic analysis, and docking revealed that aromatic residues near an iron–sulfur cluster enable flavin mononucleotide‐independent electron transfer, offering a framework for engineering improved ...

Streaming Potential of White Matter and Gray Matter in Bovine Spinal Cord under Compressive Loading

open access: yesJournal of Biomechanical Science and Engineering, 2009
The spinal cord is mainly composed of white matter and gray matter which consist of solid and liquid phases. When the tissue deforms, the liquid phase in the tissue flows out through between the solid phases.

Infrared laser sampling of low volumes combined with shotgun lipidomics reveals lipid markers in palatine tonsil carcinoma

open access: yesMolecular Oncology, Volume 20, Issue 6, Page 1513-1534, June 2026.
Nanosecond infrared laser (NIRL) low‐volume sampling combined with shotgun lipidomics uncovers distinct lipidome alterations in oropharyngeal squamous cell carcinoma (OPSCC) of the palatine tonsil. Several lipid species consistently differentiate tumor from healthy tissue, highlighting their potential as diagnostic markers.
