Ion-Exchange Process Apparatus TRIZ Cases
- Plasmid Purification via Size-Exclusion Chromatography Matrix
A porous separation matrix captures plasmids on external anion exchange surfaces while excluding them from pore interiors.
- Grafted Sulfonamide Polymer Electrolytes for Battery Safety
Grafted sulfonamide units on polymer chains provide ionic conduction pathways that eliminate corrosive liquid solvents while maintaining high conductivity.
- Cross-linked Pyrazolium Triptycene Membranes for Alkaline Fuel Cells
Cross-linked pyrazolium and triptycene polymers form ionic highways to boost hydroxide conductivity in alkaline fuel cell membranes.
- Reductive Detection Waveform for Electrochemical Analyte Measurement
Alternating voltage pulses clean electrode surfaces and eliminate dissolved oxygen interference, ensuring stable arsenic and hydrogen peroxide detection.
