Apparent contact angle and contact angle hysteresis on liquid infused surfaces. [PDF]
Soft Matter, 2016 We theoretically investigate the apparent contact angle and contact angle hysteresis of a droplet placed on a liquid infused surface. We show that the apparent contact angle is not uniquely defined by material parameters, but also has a dependence on the

Uncertainties in contact angle goniometry.
Soft Matter, 2019 The most widely used method to quantify the wetting properties of surfaces is by measuring contact angles. Even though contact angle goniometry is a powerful technique for characterizing wetting properties, it is not accurate for very hydrophobic ...

Low-cost, open-source contact angle analyzer using a mobile phone, commercial tripods and 3D printed parts [PDF]
HardwareX, 2022 Measurement of contact angle is important in many areas of science and engineering research. Contact angle analyzers are however not easily accessible due to their expensive cost, which hinders their use in research and also in education.

The contact angle of nanofluids as thermophysical property. [PDF]
Journal of Colloid and Interface Science, 2019 Droplet volume and temperature affect contact angle significantly. Phase change heat transfer processes of nanofluids - suspensions containing nanometre-sized particles - can only be modelled properly by understanding these effects. The approach proposed here considers the limiting contact angle of a droplet asymptotically approaching zero-volume as a ...

Contact angle measurement of free-standing square-millimeter single-layer graphene
Nature Communications, 2018 Experimental determination of the contact angle of a two-dimensional film is crucial to understand its wettability characteristics. Here, the authors use the captive bubble method to estimate a contact angle value of 42° ± 3° for a monolayer graphene ...

Contact angle and stability of interfacial nanobubble supported by gas monolayer [PDF]
Fundamental ResearchSince solid-liquid interfacial nanobubbles (INBs) were first imaged, their long-term stability and large contact angle have been perplexing scientists. This study aimed to investigate the influence of internal gas density and external gas monolayers on ...
