Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing nanocarbon separation methods face efficiency issues due to bubble formation at the electrode, which impairs the separation of metallic and semiconducting nanocarbons.
Innovation Solution
A nanocarbon separation device with a separation tank and electrode tubes that extend in the height direction, where the second electrode is disposed at the lower end, allowing bubbles generated at the electrode to be removed through the electrode tubes, preventing convection and improving separation efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a direct current voltage is applied to separate nanocarbons, then separation of metallic and semiconducting nanocarbons is achieved, but bubbles are generated at the electrode which move to the upper part and impair separation efficiency
Solution Approach 1:
The harmful bubbles generated at the lower electrode are extracted and removed from the separation tank through the electrode tube. The electrode tube serves as a dedicated channel that extracts bubbles from the lower electrode region and transports them to the upper region, preventing bubbles from interfering with the nanocarbon separation process
Solution Approach 2:
The electrode tube acts as an intermediary structure between the lower electrode and the dispersion liquid. It provides a separate pathway for bubble transport that is independent from the nanocarbon separation process, allowing bubbles to be removed without disrupting the electric field or the separation of metallic and semiconducting nanocarbons
2Use of energy by moving object
If bubbles are generated at the lower electrode, then electrolysis of water occurs, but bubbles move upward and cause convection that significantly impairs separation efficiency
Solution Approach 1:
Bubbles are extracted from the lower electrode through the electrode tube before they can rise and cause convection. This extraction prevents the formation of convective currents that would disrupt the stable separation of nanocarbons
Solution Approach 2:
The separation tank is segmented into distinct functional regions: the electrode tube creates a separate bubble transport channel, while the main tank region maintains stable nanocarbon separation. This segmentation isolates the bubble generation process from the separation process, preventing convection
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution effectively removes bubbles that impair separation efficiency, enabling quick and efficient separation of metallic and semiconducting nanocarbons by blocking horizontal flow and maintaining a stable separation process.
Implementation Method 1
separating the nanocarbon micelle groups into two or more nanocarbon micelle groups by applying a direct current voltage in a serial direction to the introduced, arranged and laminated dispersion liquid and holding solution
Implementation Method 2
when a direct current voltage is applied, electrolysis of water as a solvent occurs, and thus oxygen is generated at a positive electrode and hydrogen is generated at a negative electrode
