Rheology and Stability of Hydrocarbon-Based Gelled Fuels for Airbreathing Applications

open access: yesAerospace
Gelled fuels are rheologically complex, non-Newtonian fluids. They combine the benefits of both liquid and solid states, reducing risks of leakage, spilling, and sloshing during storage while maintaining the ability to be sprayed inside a combustion ...

A Comparison of Bead‐Spring and Site‐Binding Models for Weak Polyelectrolytes

open access: yesMacromolecular Theory and Simulations, EarlyView.
This study compares a site‐binding model with an implicit salt solution treatment to an explicit bead‐spring model to obtain titration curves of small weak polyelectrolytes. The implicit model accurately predicts ionization profiles in weak coupling (small Bjerrum lengths) but overestimates ionization correlations among acid groups in strong coupling ...

The Universe as a Cellular System [PDF]

open access: yesarXiv, 2014
Cellular systems are observed everywhere in nature, from crystal domains in metals, soap froth and cucumber cells to the network of cosmological voids. Surprisingly, despite their disparate scale and origin all cellular systems follow certain scaling laws relating their geometry, topology and dynamics.

Controlling Drug Release From Supramolecular Polymer Surfaces by a Click‐To‐Release Reaction

open access: yesJournal of Polymer Science, EarlyView.
We present a strategy combining reactive supramolecular additives with a covalent click‐to‐release reaction for localized drug delivery. A trans‐cyclooctene additive releases a cytotoxic drug upon tetrazine administration. Fluorescent monitoring confirms release, and cytotoxic tests show effective cancer cell death.

The effects of carboxylic acids in aluminum anodizing [PDF]

open access: yes, 2017
Hard-anodized alumina coatings were formed in sulfuric acid at low temperature and high current density in the presence of carboxylic acid additives. Citric acid, trimesic acid, mellitic acid and ethylenediaminetetraacetic acid (EDTA) were utilized in ...

Partial Melting and Structural Disorder in Models of Irradiated Amorphous Ge2Sb2Te5

open access: yesphysica status solidi (RRL) – Rapid Research Letters, EarlyView.
The evolution of the potential energy landscape of glassy Ge2Sb2Te5$\left(\text{Ge}\right)_{2} \left(\text{Sb}\right)_{2} \left(\text{Te}\right)_{5}$ during irradiation indicates the partial melting of the model structure. This view provides a thermodynamic insight into the fast recovery of the amorphous network after irradiation. The chemical disorder
