Furthermore, they establish SI-SECM as an analytical tool for mechanism-focused study of adsorbed intermediates and photocatalytic processes that occur on semiconducting and insulating surfaces, where quantification of surface reaction intermediates with view towards the nano-scale remains challenging for other electrochemical and spectroscopic approaches.
These images allow for an accurate analysis of the sample surface and quantification of surface roughness.
The mass transfer data, dropsize data and surface area quantification indicate that the free MEA content dominates spray absorption.
Dropsize measurements using a Phase Doppler Interferometer (PDI), robust cumulative drop surface area quantification, and effective interfacial area measurements with the CO2-0.1 NaOHOH system inside a 0.2 m ID laboratory spray column are presented.
A surface structural quantification based on laser profilometry (LP; Lehmann, Lehman Mess-Systeme AG, Baden-Dättwil, Germany) and atomic force microscopy (AFM; Nanoscope Dimension 3100 controller, Digital Instruments-Vecco, Santa Barbara, CA, USA) was performed on the films, as described by Chinga-Carrasco et al. [13] and Syverud et al. [14].
Today, assays that use as read-out of the signal the number count of immobilized beads on a surface for quantification of a sample's analyte concentration have been among the most sensitive and have allowed protein detection lower than the fg mL−1 concentration range.
Orthotopic tumour tissue was sectioned to achieve a maximal en face surface for quantification of tumour necrosis and apoptosis.
Finally, while an assessment of IL17RB protein levels would provide additional supportive information, we do not have intact CD4+ lymphocytes enabling suitable cell surface protein quantification.
In addition, the extensive rinsing during the 16S rRNA FISH procedure ensures that only truly adhered bacteria are present on the surface during quantification.
In this study, LP was applied for the surface topography quantification of films made from the TEMPO and C-Periodate nanocelluloses.
