Synthesis and Properties of Surface Active Agents. I.
Journal of Japan Oil Chemists' Society, 1962 The “Pickling” of steel or iron comprises removal of metal oxide on the surface by immersion in an acid. It has been found that the addition of cationic surface active agents (CSA) which have been called “Inhibitor” to acid decreases the rate of corrosion.In order to study the relationship between chemical construction of CSA and corrosion inhibitive ...

Mechanical active control of surface plasmon properties
Optics Express, 2012 We present a multilayer device which allows the control of Surface Plasmon (SP) propagation properties (propagation length and extension). A simple modification on an inner air gap thickness strongly affects SP propagation mode due to coupling with Parallel-Plate (PP) mode.

Synthesis and evaluation of some surface active agents from long chain fatty amine
Grasas y Aceites, 2007 This study continues our series of synthesis of surface active agents containing heterocyclic moiety. NHeptadecanoyl- 3-(4-oxo-4H-benzo[d][1,3]oxazin-2-yl)- acrylamide (4) was used as a new starting material to synthesize propenoxylated nonionic surface ...

Gold surface with gold nitride–a surface enhanced Raman scattering active substrate [PDF]
, 2009 The nitration of gold surfaces is a nonpolluting method, which can lead to large scale production of substrates with remarkable properties and applications. We present a topographical study of the nanoscale structure of the gold nitride surfaces produced

Surface-active cobalt cage complexes: synthesis, surface chemistry, biological activity, and redox properties [PDF]
Dalton Transactions, 2003 Amphiphilic cobalt(III) cage complexes with bridgehead octyl, dodecyl and hexadecyl hydrocarbon chain substituents have been synthesized simply by co-condensation of formaldehyde and long chain aliphatic aldehydes with the tripodal cobalt(III) hexaamine complex, [Co(sen)]3+ {sen = 4,4′,4″-ethylidynetris(3-azabutan-1-amine)}.
