Claim 1framework claimsupports2026Source 1DOI PubMed

The study establishes a unified framework based on λ for membrane selection and design and shows that targeted functionalization expands the functional range of porous membranes.

Claim 2mechanistic frameworksupports2026Source 1DOI PubMed

The pore-to-particle size ratio λ is a determinant of membrane retention and transmission performance across microfiltration and ultrafiltration.

Claim 3performance thresholdsupports2026Source 1DOI PubMed

High retention of at least 95% occurs consistently when λ is less than 0.5 across both microfiltration and ultrafiltration regimes.

Claim 4performance trendsupports2026Source 1DOI PubMed

As λ increases above 1, transmission dominates, but membrane surface modification can dramatically enhance selectivity.

Claim 5performance trendsupports2026Source 1DOI PubMed

When λ is much less than 1, flux decline is minimal although flux stability varies widely.
