Measurement of the Vaporization Enthalpy of Complex Mixtures by Correlation-Gas Chromatography. The Vaporization Enthalpy of RP-1, JP-7, and JP-8 Rocket and Jet Fuels at T = 298.15 K

, 2016
The use of correlation-gas chromatography to measure the vaporization enthalpy { Hm(298.15 K)} of complex fuels is demonstrated using RP-1, JP-7, and JP-8, which are all rocket and jet fuels. Vaporization enthalpies of 308, 341, and 441 kJ/kg have been

Toward Pore‐Engineered 3D‐Printed Materials for Sorption Water Harvesting, Interfacial Evaporation, and Radiative Cooling

Advanced Materials, EarlyView.
Water harvesting, radiative cooling, and interfacial solar evaporation are fundamentally governed by coupled heat, mass, and light transport processes. These processes are mediated by pore architecture, including pore size, connectivity, and hierarchical organization.

Framework Flexibility on Water Sorption and Transport in ZIF‐90: Insights from Neural‐Network Molecular Dynamics

Advanced Materials Interfaces, EarlyView.
A DeepMD‐based molecular dynamics framework is developed to investigate water adsorption in ZIF‐90, explicitly accounting for framework flexibility. Results show that atomistic flexibility significantly influences adsorption energetics, diffusion, and structural correlations, yielding nearly constant heat of adsorption and enhanced mobility.

Morphological Characterization of Spherulites in Silk‐Polycaprolactone Mixtures: Implications for Textured Materials

Advanced Materials Interfaces, EarlyView.
Blending silk fibroin with polycaprolactone alters crystalline organization and surface morphology. Low fibroin levels promote ring‐banded spherulites, while higher contents generate porous, pit‐like textures, though overall crystallinity remains unchanged. Solvent evaporation further modulates surface patterns.

UCST‐Responsive PMEGA: From Solution Behavior to Functional Hydrogel Surfaces

Advanced Materials Interfaces, EarlyView.
PMEGA is used as a versatile water‐based UCST‐responsive platform for engineering microstructured hydrogel coatings via a thiol–ene CLAG approach. From PMEGAs of well‐defined UCST properties, the UV‐based CLAG method provides precise control over film thickness, ranging from nanometers to micrometers, and enables high‐resolution patterning.
