Scanning Electron Microscope (SEM)
Background: To characterize the nanoscale structure prepared by the alkaline oxidation to the copper substrate.
From the SEM image in the top view (Figure 1), I found that the alkaline oxidation to copper introduces a large amount of nanoscale flake-like structure, which has a random orientation. Also, the thickness and
Superhydrophobic Materials
What is superhydrophobic?
Superhydrophobic is a concept that the surface has extremely low wettability, which is quantified by the apparent contact angle θa. Superhydrophobic material is composed of the surface featuring and low-wettability coating, such as Teflon. It is because the air trap inside the surface feature prevents water penetration,
Atmospheric Water Harvesting (AWH)
According to the World Resources Institute, there will be 3.5 billion people facing the water shortage situation by 2025. Therefore, enlarging our water source becomes an urgent problem. That is why Atmospheric Water Harvesting has been under concern. Atmospheric water is the third largest accessible water source, which constitutes
Machine Learning
Background:
I need an efficient and accurate method to annotate the droplets contained in the Time-lapse images. It is challenging for the "traditional image analysis" methods, such as image thresholding (Figure 1). Because of few things:
1. Various focus between droplets
2. Various intensity between regions
3. Segmentation
Transmission Electron Microscope (TEM)
I participated in two projects involving TEM (JEOL-2100F), which is the MXene and the Metal-Organic-Framework (MOF) project.
Starting from the MXene project, I used TEM to examine MXene at the atomic scale. Figure 1a shows the TEM image of the MXene I synthesized and exfoliated. It can be observed that
Photolithography
Background: I was planning to synthesize the micro-structure as the skeleton for the growth of the nano-roughness feature. This design is conventionally adopted to avoid the failure of the self-propelling mechanism.
To begin with, I designed the mask on AutoCad (Figure 1). Then I sent the drawing to the commercial
