Figure S5 from Hesam Khaksar et al. 2024 “A comparative nanotribological investigation on amorphous and polycrystalline forms of MoS2”: AFM image on the scratched area with the AFM (contact mode image) Fig. S5 shows a collection of images captured by the atomic force microscope, which displays scratches on two different materials. The first row shows scratches on amorphous material, while the second row shows scratches on polycrystalline material. Within each row, the force used to create the scratches was increased from 2 to 15 μN . The NANOSENSORS diamond coated DT-NCHR AFM probe was used to create the scratches and capture the images, allowing for a detailed examination of the surface features and material properties.

Molybdenum disulfide (MoS2) is commonly used as a dry lubricant due to its enhanced performance in the absence of oxygen and its elevated temperature stability,… Read More »A comparative nanotribological investigation on amorphous and polycrystalline forms of MoS2
