TOPOGRAPHICAL EVOLUTION OF MAGNETRON SPUTTERING Ti THIN FILMS DURING OXIDATION OBSERVED BY AFM

LI, XINYUE; JIN, YONGZHONG; LIU, DONGLIANG; ZENG, XIANGUANG - In: Surface Review and Letters (SRL) 18 (2011) 01, pp. 61-69

Titanium films of 120 nm thickness were magnetron sputtered on glass substrates at room temperature, and subsequently they were annealed under flowing oxygen atmosphere at different temperatures and time. Atomic force microscopy (AFM) was used to study topographic characteristics of the films,...

MONOLAYER CHARACTERISTICS OF CHITOSAN ASSEMBLED IN LANGMUIR FILMS MIXED WITH ARACHIDIC ACID

NATH, JAYASREE; NATH, RANENDU KUMAR; CHAKRABORTY, ADRITA; … - In: Surface Review and Letters (SRL) 21 (2014) 04, pp. 1450049-1

In this paper, we report our investigation on the monolayer characteristics of a nontoxic, biocompatible, and biodegradable polymer chitosan (CHS) using Langmuir–Blodgett technique. It has been observed that pure CHS do not form stable monolayer. However, when CHS is mixed with arachidic acid...

EVOLUTION OF THE COPPER SURFACE IN THE COURSE OF OXIDATION BY CCl4–L (L=THF, DMF, DMSO): SCANNING PROBE MICROSCOPE STUDY

PANTELEEV, S. V.; MASLENNIKOV, S. V.; IGNATOV, S. K.; … - In: Surface Review and Letters (SRL) 20 (2013) 03, pp. 1350023-1

The evolution of compact surface of the 100 nm copper film deposited on the glass-ceramics doped with vanadium coating … roughness of copper films. The amount of the metal reacted has an almost linear dependence on the reaction time. AFM scans … indicate that there is the same mechanism of the reaction between copper and carbon tetrachloride for all solvents. …

Simple transform methods of a force curve obtained by surface force apparatus to the density distribution of a liquid near a surface

Amano, Ken-ichi; Takahashi, Ohgi - In: Physica A: Statistical Mechanics and its Applications 425 (2015) C, pp. 79-89

We propose two simple methods that transform a force curve obtained by a surface force apparatus (SFA) into a density distribution of a liquid near a surface of the SFA probe. The transform methods are derived based on the statistical mechanics of simple liquids, where the liquid is an ensemble...
