Soybean-Oil-Based CO2-Switchable Surfactants with Multiple Heads
Molecules, 2021 Oligomeric surfactants display the novel properties of low surface activity, low critical micellar concentration and enhanced viscosity, but no CO2 switchable oligomeric surfactants have been developed so far. The introduction of CO2 can convert tertiary

The onset of solar cycle 24: What global acoustic modes are telling us
, 2009 We study the response of the low-degree, solar p-mode frequencies to the unusually extended minimum of solar surface activity since 2007. A total of 4768 days of observations collected by the space-based, Sun-as-a-star helioseismic GOLF instrument are ...

Features of medical implant passivation using anodic oxide films [PDF]
, 2016 The passivation ability of metals from groups IV and V of the Periodic Table is considered. Anodic treatment is able to neutralize the increase of metal hardening when comminuting grains to nanometre sizes.

Activity of surface active substances determined from their surface excess [PDF]
Physical Chemistry Chemical Physics, 2005 Commonly, the surface excess is determined from surface tension measurements via the Gibbs equation. This equation relates the activity (chemical potential), the surface excess, and the surface tension. When knowing two out of the three quantities, the third one can be calculated.

Palmitoylcarnitine, a surface‐active metabolite [PDF]
FEBS Letters, 1996 Palmitoylcarnitine is a well‐known intermediate in mitochondrial fatty acid oxidation. Less known are its properties as a surfactant, with a capacity to solubilize biological membranes similar to that of many synthetic detergents used in the biochemical laboratory.
