2026

  1. Prediction of Polymer Adhesion and Inverse Design of Heterogeneous Surfaces using Data-Driven Approaches

    S. Panigrahy, A. James, D. Nayar

    Molecular Systems Design & Engineering · 2026 · under review

    Forward prediction at R² = 0.995, and a tandem network that designs surface patterns for a target free-energy profile.

2025

  1. Data-driven prediction of polymer surface adhesion using high-throughput MD and hybrid network models

    S. Panigrahy, A. James, D. Nayar

    AI for Accelerated Materials Design (AI4Mat) Workshop, NeurIPS · 2025 · workshop paper

    A CNN–GRU–attention network trained on about 470k umbrella-sampling runs predicts full adhesion free-energy profiles.

2024

  1. Differential local ordering of mixed crowders determines effective size and stability of ss-DNA capped gold nanoparticle

    S. Panigrahy, D. Nayar

    The Journal of Chemical Physics 160, 014901 · 2024

    Small crowders act through soft, direct adsorption rather than depletion; a glycine + serine mixture gives the largest particle radius.

  2. In Silico View of Crowding: Biomolecular Processes to Nanomaterial Design

    S. Rajput, S. Panigrahy, D. Nayar

    ACS Omega 9, 29953–29965 · 2024

    A review of how simulation has reshaped our picture of crowding, from protein folding to nanomaterial design.

2023

  1. Structure, energetics and dynamics in crowded amino acid solutions: a molecular dynamics study

    S. Panigrahy, R. Sahu, S. K. Reddy, D. Nayar

    Physical Chemistry Chemical Physics 25, 5430–5442 · 2023

    A one-parameter NBFIX correction removes artificial aggregation and recovers experimental osmotic coefficients, viscosities and diffusivities.

In preparation

  1. Effect of mixed molecular crowding environment on the conformational properties of ss-DNA

    S. Panigrahy, D. Nayar

    Manuscript in preparation

    Crowder chemistry, not just excluded volume, decides whether a DNA strand extends, stiffens or folds.

  2. Effect of size on stability of citrate adsorbed to gold nanoparticle: assessing polarized and non-polarized models

    S. Panigrahy, D. Nayar

    Manuscript in preparation

    Metal polarizability switches citrate from non-specific coating to facet-selective binding on {111}.
