Restructuring polymers via nanoconfinement and subsequent release

open access: yesBeilstein Journal of Organic Chemistry, 2012
During the past several years my students and I have been utilizing certain small-molecule hosts to create nanostructured polymers. This is accomplished by first forming noncovalently bonded inclusion complexes (ICs) between these small-molecule hosts ...

Gelation of Poly(Vinylidene Fluoride) Solutions in Native and Organically Modified Silica Nanopores

open access: yesMolecules, 2018
The purpose of this study is to highlight the surface and size effects of the nanopores on the thermodynamics and kinetics of gelation. The effects have been probed by applying differential scanning calorimetry to poly(vinylidene fluoride) solutions in ...

Conjugated Polymers Engineered for Flexible/Stretchable Electronics

open access: yesJournal of Polymer Science, EarlyView.
This review highlights glass transition temperature (Tg) as the central parameter linking molecular structure to device performance in conjugated polymers. By tuning backbone rigidity, side‐chain architecture, and dynamic bonding, Tg governs the balance between π–π stacking–enabled charge transport and mechanical compliance.

Unraveling Water Sorption in Single‐Crystal MOFs: Insights from Spectroscopy and Modeling on the Role of Structure, Composition, and Guest Molecules

open access: yesSmall, EarlyView.
Water scarcity drives the search for efficient atmospheric water harvesting (AWH) materials. This study explores the impact of metal substitution (Zr to Hf) and linker exchange (fumaric to trimesic acid) on the water sorption performance of MOF‐801 and MOF‐808.

Hysteresis, force oscillations and non-equilibrium effects in the adhesion of spherical nanoparticles to atomically smooth surfaces

open access: yes, 2005
Molecular dynamics simulations are used to examine hysteretic effects and distinctions between equilibrium and non-equilibrium aspects of particle adsorption on the walls of nano-sized fluidfilled channels.

Energy Transfer in Nanodroplet‐Based Luminescent Solar Concentrators

open access: yesSmall, EarlyView.
We present novel luminescent solar concentrators (LSCs) featuring polymer composites with fluorescent dye‐doped oil nanodroplets. This liquid environment ensures high dye solubility and preserves fluorescence quantum yields, even at high local dye concentrations.

Nanoconfined relaxation enables commercial dielectric polymer to insulate at 300 °C

open access: yesInfoMat
As dielectric polymers are confined to nanoscale dimensions, anomalous enhancements in electrical resistivity have been widely inferred and exploited in nanocomposites and multilayered structures—yet direct experimental validation of the mechanisms ...

Pore Size and Wettability Control Dissolution Trapping Regimes of CO2 in Nano Porous Media

open access: yesGeophysical Research Letters, Volume 53, Issue 10, 28 May 2026.
Abstract We simulate supercritical carbon dioxide (scCO2 ${\text{scCO}}_{2}$) dissolution in water in nano/submicron pore‐throats (14.3–21.5 nm) using a multi‐component, multiphase pseudopotential lattice Boltzmann model closed by a Peng–Robinson equation of state.
