Wetting Behaviour of Water, Ethanol, Rhamnolipid, and Triton X-165 Mixture in the Polymer–Solution Drop–Air System

Molecules, 2023
Despite the fact that the wetting properties of multicomponent mixtures including the surface active compounds play a very important role in many practical applications, they are not sufficiently known.

Physicochemical Phenomena in the Roasting of Cocoa (Theobroma cacao L.) [PDF]

, 2022
The quality of cocoa depends on both the origin of the cacao and the processing stages. The roasting process is critical because it develops the aroma and flavor, changing the beans’ chemical composition significantly by chemical reactions induced by ...

Wettability of Quartz by Ethanol, Rhamnolipid and Triton X-165 Aqueous Solutions with Regard to Its Surface Tension

Colloids and Interfaces, 2023
The wettability of quartz by different liquids and solutions plays a very important role in practical applications. Hence, the wetting behaviour of ethanol (ET), rhamnolipid (RL) and Triton X-165 (TX165) aqueous solutions with regard to the quartz ...

Chemical Phenomena of Atomic Force Microscopy Scanning [PDF]

, 2018
Atomic force microscopy is widely used for nanoscale characterization of materials by scientists worldwide. The long-held belief of ambient AFM is that the tip is generally chemically inert but can be functionalized with respect to the studied sample ...

Multi-scale phenomena in heterogeneous catalytic processes - impact of chemical phenomena under the micro-scale level on catalyst

, 2004
Catalyst design requires consideration of all the different dimensional scales involved in heterogeneous catalysis. Identifying phenomena at every scale and defining all the dominant mechanisms are of significance to the multi-scale analysis. Rather than

Surface Activity of Natural Surfactants Extracted from Sapindus mukorossi and Sapindus trifoliatus Soapnuts

Colloids and Interfaces, 2021
Surfactants derived from renewable sources such as plants are an ecological alternative to synthetic surfactants. Aqueous solutions of natural surfactants extracted from soapnuts obtained from two plants, Sapindus mukorossi and Sapindus trifoliatus, were

Dissipative particle dynamics simulation of wettability alternation phenomena in the chemical flooding process

, 2009
Wettability alternation phenomena is considered one of the most important enhanced oil recovery (EOR) mechanisms in the chemical flooding process and induced by the adsorption of surfactant on the rock surface. These phenomena are studied by a mesoscopic
