And the article was included in Tribology Letters in 2008.Computed Properties of C7H13ClN2 This article mentions the following:
Ionic liquids (ILs) are considered as a new kind of lubricant for micro/nanoelectromech. system (M/NEMS) due to their excellent thermal and elec. conductivity However, so far, only few reports have investigated the triboltribol. behavior of mol. thin films of various ILs. Evaluating the nanoscale tribol. performance of ILs when applied as a few nanometers-thick film on a substrate is a critical step for their application in MEMS/NEMS devices. To this end, four kinds of ionic liquid carrying Me, hydroxyl, nitrile, and carboxyl group were synthesized and these mol. thin films were prepared on single crystal silicon wafer by dip-coating method. Film thickness was determined by ellipsometric method. The chem. composition and morphol. were characterized by the means of multi-technique X-ray photoelectron spectrometric anal., and at. force microscopic (AFM) anal., resp. The nano- and microtribol. properties of the ionic liquid films were investigated. The morphologies of wear tracks of IL films were examined using a 3D non-contact interferometric microscope. The influence of temperature on friction and adhesion behavior at nanoscale, and the effect of sliding frequency and load on friction coefficient, load bearing capacity, and anti-wear durability at microscale were studied. Corresponding tribol. mechanisms of IL films were investigated by AFM and ball-on-plane microtribotester. Friction reduction, adhesion resistance, and durability of IL films were dependent on their cation chem. structures, wettability, and ambient environment. In the experiment, the researchers used many compounds, for example, 1-Methyl-3-propylimidazolium Chloride (cas: 79917-89-8Computed Properties of C7H13ClN2).
1-Methyl-3-propylimidazolium Chloride (cas: 79917-89-8) belongs to imidazole derivatives. Many natural products, especially alkaloids, contain the imidazole ring. These imidazoles share the 1,3-C3N2 ring but feature varied substituents. The pharmacophore of imidazole exists in bioactive compounds including amino acids, plant growth regulators and therapeutic agents.n increase of the alkyl chain length of the alcohols.
