Semi-Permeable Membranes TRIZ Cases
- CO2 Separation Membranes Using ML Inverse Materials Design
Machine learning predicts and generates membrane molecules for CO2 separation, cutting screening cost and speeding validation.
- Anti-IL-1R1 Antibody Purification for Acidic Species Reduction
Sequential cation and anion exchange chromatography lowers acidic species and impurities in anti-IL-1R1 antibodies to improve stability and safety.
- Polyarylene Ether Sulfone Process With Low Cyclic Oligomers
Controlled heating and monomer ratios produce high-molecular-weight polyarylene ether sulfones with low volatiles and cyclic dimers for cleaner membrane processing.
- Continuous Viral Clearance Testing With Controlled Virus Spiking
Controlled constant-rate protein flow and virus spiking enable reproducible viral clearance testing for continuous purification and filtration.
- Catalytic CO2 Membrane With Hydrated Nanochannels for Low-Energy Capture
Hydrated nanochannels and an immobilized catalyst convert CO2 continuously with lower energy use and stable membrane operation.
- Layered Air Filter Medium for Low Pressure Loss and Dust Holding
An upstream pre-collection layer plus dual porous films raises dust holding capacity while keeping fine-particle capture high and pressure loss low.
- Porous CO2 Capture Media Using Bicarbonate Regeneration
Hydrophilic and hydrophobic porous media convert CO2 to bicarbonate and back, cutting regeneration energy while maintaining capture efficiency.
- Ammonium-Modified Ion Exchange Membranes for Ketone Solvents
Ammonium-functional ion exchange membranes remove metal ions from ketone solvents while preventing color bodies and oligomer formation.
- Ubx-Protein A Fusion Matrix for High-Capacity Antibody Purification
Covalently fusing Protein A or Z domains to Ubx materials boosts antibody binding capacity and prevents ligand leaching during purification.
- Vacuum-Driven Plasma Separation Membrane for Rapid Blood Filtration
A track-etched membrane and single vacuum source separate plasma from whole blood in under a minute with high purity and low hemolysis.
- Continuous Isoelectric Fractionation for High-Purity Nanocarrier Isolation
A bipolar-membrane pH gradient separates extracellular nanocarriers by isoelectric point, improving purity, yield, and throughput.
- Artificial Gill Garment Using Hydrophobic Membranes for Underwater Breathing
A hydrophobic porous membrane garment enables underwater gas exchange while blocking water, reducing bulk versus conventional diving gear.
- Deaerator Pressure Detection Layout to Prevent Condensation Contact
A downward-facing pressure path lets condensed or leaking liquid drain away, protecting the pressure detection element in a deaerator.
- Apertured Polymer Filter Sheets With Nanoparticles for Lower Pressure Drop
Embedded nanoparticles capture contaminants inside apertured polymer filter sheets while reducing cross-flow pressure drop in support membranes.
