Measurements of advancing contact angles for aqueous solution of Triton X-100 (TX-100) with methanol, ethanol and propanol mixtures and Triton X-165 (TX-165) with the same alcohols on quartz surface were carried out. From the obtained results it appeared that...

Effect of surfactants on the voltammetric response and determination of an antihypertensive drug.

Talanta

Atta NF, Darwish SA, Khalil SE, Galal A.
PMID: 19071781
Talanta. 2007 Jun 15;72(4):1438-45. doi: 10.1016/j.talanta.2007.01.053. Epub 2007 Feb 01.

The effect of adding surface-active agents to electrolytes containing terazosin, an antihypertensive drug, on the voltammetric response of glassy carbon electrode was studied. The current signal due to the oxidation process was a function of the amount of terazosin,...

Effect of anionic surfactant and short-chain alcohol mixtures on adsorption at quartz/water and water/air interfaces and the wettability of quartz.

Measurements of the advancing contact angles for aqueous solutions of sodium dodecyl sulfate (SDDS) or sodium hexadecyl sulfonate (SHS) in mixtures with methanol, ethanol, or propanol on a quartz surface were carried out. On the basis of the obtained...

Natural product antifoulants: One perspective on the challenges related to coatings development.

Biofouling

Rittschof D.
PMID: 22115297
Biofouling. 2000;15(1):119-27. doi: 10.1080/08927010009386303.

Fouling of surfaces by abiotic and biotic substances has molecular, microbial, and macro-organismal levels of organization. Fouling involves molecular bonding and biological adhesives. Existing commercial solutions to fouling are antifouling or foul-release. Antifouling uses broad-spectrum biocides which kill foulers...
