Nanoscale chemical and structural investigation of Mg-doped GaN nanowires using EDS and WDS on SEM [PDF]

EPJ Web of Conferences
Semiconductors are the basis of many of today's technical products and therefore an important foundation of our modern economy. One material that is currently the subject of intensive research is doped gallium nitride (GaN), which has outstanding ...

From hemolymph to in-vivo: The potential of a 1 mm microlitre flow probe with separate lock chamber for NMR metabolomics in mass limited environmental samples

Journal of Magnetic Resonance Open, 2022
Metabolomics is one of the leading approaches for understanding the toxic-mode-of-action of environmental contaminants. Nuclear Magnetic Resonance (NMR) spectroscopy has been commonly used in metabolomic studies; however, its main drawback is its ...

Calpain small subunit homodimerization is robust and calcium‐independent

FEBS Letters, EarlyView.
Calpains dimerize via penta‐EF‐hand (PEF) domains. Using single‐molecule force spectroscopy, we measured the strength and kinetics of PEF–PEF homodimer binding. The interaction is robust, shows a transient conformational step before dissociation, and remains largely insensitive to Ca2+.

Viscosity of yttrium oxide (Y2O3) and magnesium-aluminum spinel (MgAl2O4) nanopowder suspensions in ethyl alcohol

Archives of Mechanics, 2013
We report results of rheological experiments on suspensions of nanopowders. In this work we have used two ceramic nanopowders such as magnesium-aluminum spinel (S30CR Baikowski – MgAl2O4) and yttrium oxide (Y2O3) suspended in ethyl alcohol.

Degradation mechanism of the von Willebrand factor A2 domain by nattokinase

FEBS Letters, EarlyView.
Nattokinase, a natto‐derived protease, exhibits potent antithrombotic effects. This study demonstrates that nattokinase directly cleaves the von Willebrand factor (vWF) A2 domain in vitro. Unlike the native regulator ADAMTS13, nattokinase degrades folded vWF independently of shear stress.

Rapid quantitative screening of 15 synthetic cannabinoids in urine using direct analysis in real time tandem mass spectrometry: Screening method validation and cross-correlation study with liquid chromatography tandem mass spectrometry

Green Analytical Chemistry
Preliminary screening methods for detection of urine-based drugs of abuse are typically selected based on their ease of automation, cost effectiveness, and ability to deliver rapid results.

Modulation of Homer1 EVH1 domain internal dynamics by putative autism‐associated mutations

FEBS Letters, EarlyView.
The putative autism‐associated M65I and S97L variants of the EVH1 domain of the postsynaptic scaffold protein Homer1 do not exhibit substantial changes in their overall structure or partner binding. Both of them, but especially the M65I variant, show altered internal dynamics relative to the wild‐type domain on the μs‐ms timescale, indicated by the ...
