CISS-Selective Electrospun Nanofiber Heavy-Metal Capture

TITLE: CISS-Selective Electrospun Nanofiber Heavy-Metal Capture

PROBLEM: Electrospun mats can embed chiral biomass through a high-surface-area fiber network, offering many spin-selective sites for capture. The difficulty is that fiber spinning can disorder chiral groups, so a mat may contain the right molecules yet present them in a way that weakens spin selectivity. Capture teams need preserved versions of each fiber recipe and its uptake record to learn which spinning conditions keep the chiral effect intact.

SOLUTION: Storage Copy Data Management would keep versioned copies of CISS electrospun capture mats — spinning conditions, chiral loading, fiber structure intent, DFT binding predictions, intended spin-selective step, and batch-isotherm results — with rollback to any earlier mat. The capability would preserve drying and regeneration energy with each version so a working fiber recipe is never lost to an unrecorded change. Water-based, low-temperature spinning variants would be retained as distinct versions.
