X-ray micro-CT imaging to study foliar water uptake mechanisms in plants with contrasting leaf topography. [PDF]

open access: yesNew Phytol
Summary Formation of an aqueous continuum from the leaf surface to the sub‐stomatal cavity is a key process, affecting the foliar entry of solutes, particles, and pathogens. However, the factors controlling the transition from a water droplet to the formation of a continuous water film remain poorly understood.

Biochemical parameters, dynamic tensiometry and circulating nucleic acids for cattle blood analysis: a review [PDF]

open access: yesPeerJ, 2020
The animal’s blood is the most complicated and important biological liquid for veterinary medicine. In addition to standard methods that are always in use, recent technologies such as dynamic tensiometry (DT) of blood serum and PCR analysis of particular

In situ force-balance tensiometry [PDF]

open access: yesExperiments in Fluids, 1999
Although a fundamental physical parameter, surface tension is difficult to measure. Common tensiometry inaccur- acy comes from failure to control air—liquid—solid contact conditions, or account for liquid meniscus geometry and buoyancy corrections. This paper describes an in situ ten- siometry technique, based on withdrawal of a thin-walled tube from ...

Are Grignard Reactions in Deep Eutectic Solvents Interface‐Driven?

open access: yesAngewandte Chemie, Volume 137, Issue 42, October 13, 2025.
Experimental and molecular dynamics studies of acetophenone, alongside a computational analysis of i‐PrMgCl in a biphasic ChCl:2Gly DES/THF solution, offer valuable insights into the remarkable efficiency of the Grignard reaction under these conditions.

Development of a new composite surface tensiometry parameter for quality evaluation of the maturation process of peloids by contact angle method [PDF]

open access: yesBalneo and PRM Research Journal
With the introduction of the rheological and surface tensiometry approaches, peloids started to be viewed as a geological complex system that needed to be characterized in an integrated way.

Interfacial Tension Sensor for Low Dosage Surfactant Detection

open access: yesColloids and Interfaces, 2021
Currently there are no available methods for in-line measurement of gas-liquid interfacial tension during the flotation process. Microfluidic devices have the potential to be deployed in such settings to allow for a rapid in-line determination of the ...

Metabolism and motility in prebiotic structures [PDF]

open access: yes, 2011
Easily accessible, primitive chemical structures produced by self-assembly of hydrophobic substances into oil droplets may result in self-moving agents able to sense their environment and move to avoid equilibrium.
