IBM System Storage Ideas Portal


This portal is to open public enhancement requests against IBM System Storage products. To view all of your ideas submitted to IBM, create and manage groups of Ideas, or create an idea explicitly set to be either visible by all (public) or visible only to you and IBM (private), use the IBM Unified Ideas Portal (https://ideas.ibm.com).


Shape the future of IBM!

We invite you to shape the future of IBM, including product roadmaps, by submitting ideas that matter to you the most. Here's how it works:

Search existing ideas

Start by searching and reviewing ideas and requests to enhance a product or service. Take a look at ideas others have posted, and add a comment, vote, or subscribe to updates on them if they matter to you. If you can't find what you are looking for,

Post your ideas

  1. Post an idea.

  2. Get feedback from the IBM team and other customers to refine your idea.

  3. Follow the idea through the IBM Ideas process.

Hofmeister Ion-Specific Gradient Multilayer Selective Ion Sensors

PROBLEM: A gradient sensor separates ions across graded layers, yet Hofmeister neighbours interact differently at each grade, so selectivity is a property of the whole graded sequence in a specific background. A calibration that ignores the background cannot tell whether a signal change came from the target ion or from a shift in the ion series.

SOLUTION: Storage Copy Data Management would preserve versioned gradient-sensor records that include the full grade profile, DFT selectivity basis per grade, multi-ion calibration, and background composition for each reading. Any disputed reading could be traced to the exact gradient copy and background that produced it.

EVIDENCE BASIS: DOCUMENTED — Hofmeister / ion-specific effects; Source: 1888 series, modern molecular basis. DFT (Kohn–Sham 1965) predicts which surface groups bind which metal ions; biosorption validation uses batch isotherms qe = (C0 − Ce)V/m and Langmuir/Freundlich models, textbook DOCUMENTED. Gradient multilayers grade composition/porosity through the stack.
