The phrase "and type of surface active" is not correct in written English as it is incomplete and lacks clarity.
It could be used in a context discussing different types of surface-active agents or materials, but it needs to be part of a complete sentence for proper usage.
Example: "We need to analyze the chemical properties and type of surface active agents used in this formulation."
Alternatives: "and category of surfactants" or "and kind of surface-active agents".
Information collected with each surface sampled included: visit number, hospital ward, surface location, environmental surface sampled, and type of surface material.
Results were analyzed in terms of density and type of active surface sites, applied potential and alcohol concentration.
Particle distribution, concentration and morphology, surface free energy, surface tension and the presence of various types of surface-active agents were all studied.
Type and concentration of surface-active components have been shown to impart considerably stability and rheological property changes to the interfacial films, thus making the coalescence mechanism more complicated.
Simultaneous measurement signals from all matrix cells (Fig. 5) by a charge-coupled device (CCD) and digital processing provide an opportunity to increase selectivity analysis and to at the same time to determine the concentration and type of many active gases adsorbed on the surface of metal oxide.
We hypothesize that this crystal structure influences the properties of the carbon surfaces and affects the number and type of active sites for functionalization.
The number of desorption peaks reveals the types of catalyst surface active sites.
Two types of anionic surface active agents, sodium lauryl sulfate (K12) and α-olefin sulfonate (AOS), were used as frothers.
The various structures of fat observed during Swiss-type cheese production and the organization of surface-active material at the interface have been reported (Lopez et al. 2006; 2008) and recently highlighted (Hickey et al. 2015).
The correlation of the results obtained from these two techniques with the n-butane hydrogenolysis reaction test provides useful information about the type and distribution of the surface active sites.
