Synthesis and surface active properties of cationic surface active agents from crude rice bran oil
Grasas y Aceites, 1999 Cationic surfactants of 2-hidroxy-3-(2- alkylamidopolyethyl amino) propane-1-triethylammonium hydroxides (ix-xui)a-d were prepared from fatty acids (i)a-d [palmitic, stearic, oleic, linoleic acid] and mixed fatty acids of crude rice bran oil ie [RBO ...

Surface-active properties of Candida albicans [PDF]
Applied and Environmental Microbiology, 1989 Cell surface hydrophobicity may be an important factor contributing to the virulence of Candida yeast cells. Surface hydrophobic and surface polar groups would be required for a yeast cell to act as a surface-active agent. In this report, the surface activities of whole yeast cells were measured.

Surface properties-dependent antifungal activity of silver nanoparticles
Scientific Reports, 2022 AbstractSilver nanoparticles (AgNPs) exhibit unusual biocidal properties thanks to which they find a wide range of applications in diverse fields of science and industry. Numerous research studies have been devoted to the bactericidal properties of AgNPs while less attention has been focused on their fungicidal activity.

A simple representation of surface active organic aerosol in cloud droplet formation [PDF]
Atmospheric Chemistry and Physics, 2011 Atmospheric aerosols often contain surface active organics. Surface activity can affect cloud droplet formation through both surface partitioning and surface tension reduction in activating droplets.

Seismic inference of 57 stars using full-length Kepler data sets [PDF]
, 2017 We present stellar properties (mass, age, radius, distances) of 57 stars from a seismic inference using full-length data sets from Kepler. These stars comprise active stars, planet-hosts, solar-analogs, and binary systems.

Review of Capillary Rise Experiments for Surface-Active Solutes in the Subsurface
Geotechnics, 2022 Surface-active solutes that exist in the subsurface either naturally (humic acid) or as a result of anthropogenic activities (alcohols, surfactants, PFAS) alter the hydraulic and geotechnical properties of the unsaturated porous media.
