Influence of experimental variables on the measure of contact angle in metals using the sessile drop method
(Elsevier, 2015-08)
The sessile drop method is an easy and fast method used to measure the contact angle between solids and liquids. The value of the contact angle is used in surface characterization, in particular the wettability of solid ...
SESSILE DROP CONTACT ANGLE METHOD
(ELSEVIER, 2003)
Existing methods for determining the contact angle as a measure of the water repellency of soils are either indirect, or cumbersome and time-consuming. Our objective was to develop a new method that is simpler than the ...
Construction and calibration of a goniometer to measure contact angles and calculate the surface free energy in solids with uncertainty analysis
(Elsevier, 2018-12)
Here, we present the construction and calibration of a low-cost goniometer to measure contact angles by the sessile drop method. Besides, we propose a simple and fast method to calculate the uncertainty in the determination ...
Molhabilidade em amostras de Araucaria angustifolia e Pinus elliottii após tratamento térmico e envelhecimento
(Universidade de São Paulo - Instituto de Pesquisas e Estudos Florestais - IPEFPiracicaba, 2011-12)
Medidas de ângulo de contato, juntamente com as de massa específica, foram realizadas com o intuito de melhor compreender as características de molhabilidade de duas espécies de madeiras, Araucaria angustifolia e Pinus ...
Analysis of the results of surface free energy measurement of Ti6Al4V by different methods
(Elsevier, 2015-08)
Surface Free Energy (SFE) of solids should be calculated using theoretical models. The contact angle (CA) measurement on a surface is considered the most practical way to obtain the SFE. The results of five methods based ...
Surface properties and permeability to calcium chloride of Fagus sylvatica and Quercus petraea leaves of different canopy heights
(2018-04)
Plant surfaces have a considerable degree of chemical and physical variability also
in relation to different environmental conditions, organs and state of development.
The potential changes on plant surface properties ...
Nanopore-Enhanced Drop Evaporation: When Cooler or More Saline Water Droplets Evaporate Faster
(American Chemical Society, 2020-01)
The evaporation of water droplets on surfaces is an ubiquitous phenomenon in nature and has critical importance in a broad range of technical applications. Here we show a substantial enhancement of liquid evaporation rate ...
Sliding of drops on mesoporous thin films
(Royal Society of Chemistry, 2020-03)
There is great interest in developing surfaces with enhanced properties for the sliding of liquid droplets. Here we show that both water and oil droplets placed on mesoporous thin film surfaces slide at relatively small ...
