Kelvin Probe Force Microscopy in Bionanotechnology: Current Advances and Future Perspectives

open access: yesAdvanced Materials, EarlyView.
Kelvin probe force microscopy (KPFM) enables the nanoscale mapping of electrostatic surface potentials. While widely applied in materials science, its use in biological systems remains emerging. This review presents recent advances in KPFM applied to biological samples and provides a critical perspective on current limitations and future directions for

Comparing different application procedures of the water drop penetration time test to assess soil water repellency in a fire affected Sicilian area

open access: yesCATENA, 2019
Abstract The Water Drop Penetration Time (WDPT) technique was applied in two subsequent years (2016 and 2017) to check surface soil water repellency (SWR) in a Sicilian mountain area affected by a wildfire on June 2016. A total of 93 sites were sampled and from 3 to 100 droplets were used to characterize a site.

Characterizing water repellency indices: Contact angle and water drop penetration time of hydrophobized sand

Soil Science and Plant Nutrition, 2008
Abstract The accuracy and the reproducibility of water repellency measurements can be improved with the use of proper measurement techniques. The purpose of this study is to compare the contact angles obtained using three different methods and to examine the relationship between contact angle and water drop penetration time (WDPT) using non-repellent ...

Clay effects on the contact angle and water drop penetration time of model soils

Soil Science and Plant Nutrition, 2010
Abstract Clay is an important factor that affects soil water repellency. The purpose of the present study was to assess the effects of clay content on contact angle and water drop penetration time (WDPT), and to examine their relationship. Model soils were prepared with silica sand and kaolinite, and hydrophobized using stearic acid (SA). The effect of
