ABSTRACT
The deposition of MoS2solid lubricant on metal surfaces by non-acid deposition is the most
widely used method in aviation and space. The MoS2 film formed by the non-acid deposition is
amorphous when the temperature of the matrix is 160 ° or less, and becomes crystalline when
the temperature is higher. [2] The amorphous film has a smaller friction coefficient than the
crystalline film. [3] In this study, the amorphous film formation conditions of MoS2 were
determined theoretically and the friction coefficient was measured in DC cathodic dep

DKM has not considered the detailed characteristic parameters of the solid sorbent in such a microscopic way as unreacted shrinking core model(SCM) or general regression model (GRM) but in a macroscopic way. Therefore, DKM can be extensively applied to the kinetic analysis of noncatalytic heterogeneous reaction or adsorption processes without the requirement of structural property for sorbents.

Fatty acids composition in grape seed are analyzed. Soxhlet extraction method toextract the fatty oil in the grape seed oil,with potassium hydroxide methanol solution to methyl esterof fatty acid in fatty oil,and gas chromatography-mass spectrometry instrument is analyzed. The results showthat 6 fatty acids are detected in the mountain grape seed,the major fatty acids are linoleic acid and oleic acid.

In our letter, the adsorption of Co(II), Hg(II) and Ag(I) from fuel ethanol by silica gel supporte
d sulfur-containing PAMAM dendrimers [Fuel 199 (2017) 91–101 and 206 (2017) 80–88] were
reevaluated using deactivation kinetics model (DKM). As the result, the reaction orders newly
were estimated and the calculated rate constants were quantitatively compared on both ads
orbate and adsorbents.
