starting materials [17], [18], the introduction of a degree of unsaturation, amido, or ester group to the surfactant chain as the degradable functional groups [19], [20], and the increase of the surfactants' hydrophobic chain length as the way of reducing the dosage of surfactants [21],...
The peptidyl-tRNAs functioned as genetically-specified lipid analogues with hydrophobic tails (ancestral signal peptides) and hydrophilic polynucleotide heads. Protoribosomes arose from two cooperating RNAs: peptidyl transferase (large subunit) ... T Cavalier-Smith - 《Journal of Molecular Evolution》 被...

material comprising a hydrophilic substrate coated on the entire surface of one side thereof with a hydrophobic foam with open porosity (material type single sided skin) and made integral so that their faces entirely coated with said hydrophobic foam are oriented in the same direction, preferably ...
Note that, in some instances, the hydrophilic head of the amphiphile can interact with either the water or the organic solvent. However, the hydrophobic tail promotes interactions between the solvent and the amphiphile, by rendering the amphiphile immiscible in water. This is for instance the case...
The luminal surface of the tube can be coated with TEFLON, a hydrophobic coating such as parylene, or a hydrophilic coating such as polyvinyl alcohol or polyethylene glycol. In some embodiments, the rigid suction tube can comprise a polymer tube reinforced with a metal braid, a coiled tube, ...
With reference to water droplets (other liquids), we assumed a super-hydrophobic (super-amphiphobic) behavior for θ greater than 150°, hydrophobic (amphiphobic) behavior for θ between 90° and 150°, hydrophilic (amphiphilic) behavior for θ between 10° and 90°, and super-hydrophilic (...
1. Introduction Traditional surfactants are composed of hydrophilic and hydrophobic groups. How- ever, due to the separation caused by the electric repulsion among the ionic head groups or the hydration effect of the ionic groups [1,2], it is difficult for these groups to arrange closely at ...
In the fluid mosaic model, lipids are arranged in a bilayer with the polar (hydrophilic) heads facing outward towards the aqueous environment and the non-polar (hydrophobic) tails facing inward, away from water. Hint: Visualize the structure of the lipid bilayer to understand the orientation of...
These dimeric surfactants possess two or more hydrophilic with two or more hydrophobic head groups, chemically bonded with a linker, called the spacer group. These kinds of surfactants are used mainly in homogeneous catalytic reactions, as well as for solubilisation, emulsification, and many more ...
