Images are more powerful than words!
In the realm of materials science, visualization methods serve as vital tools for analyzing and presenting scientific research. Now, consider the intriguing prospect of infusing a touch of artistic creativity into these techniques.
Lunch atop a AFM Cantilever
90 years later! Now, 10 micron Empire State workers are sitting on an atomic force microscope (AFM) cantilever with a huge (40 micron) attached colloid used for the lateral force calibration.
Have you ever heard of “Minami-Tori-shima”? A triangular island in the Pacific Ocean! But this one is the “2D island” with the thickness of only 6.5 Angstrom. This image illustrates the atomic force microscopy (AFM) topography 3D image of a single layer MoS2 grown using the CVD technique, then transferred on top of a SiO2 substrate. The mountains represent the 2D MoS2 nucleation spots. This image was taken using the AFM-contact mode after immersing the single layer MoS2 in oil (n-hexadecane).
A part of 3MT talk:
Your car’s engine efficiency suffers from friction that occurs at various mechanical components like piston and cylinder. These friction losses increase the fuel consumption and have a direct impact on greenhouse gasses emission and “climate change”. The only solution for Mitigating friction – is developing efficient lubricants.
In the same way, we use oil drops to reduce the squeaking of the door – they can be used for engines. However, to improve the performance of the oil – a small percentage of friction-reducing agents are required. These tiny robots which we call as lube additives.
Ice-cream Scopes
Reverse tip imaging is employed to characterize the silica particle probe attached to an AFM cantilever. Through this technique, the dimensions of the colloid are measured, surface roughness is evaluated, and these measurements are integrated as part of lateral force calibration.
