Evaluation of Norrish’s Equation for Correlating the Water Activity of Highly Concentrated Solutions of Sugars, Polyols, and Polyethylene Glycols

, 2010
Norrish’s equation, $$a_{{\text{w}}} = X_{{\text{w}}} \exp {\left( { - KX^{2}_{{\text{s}}} } \right)}$$, where aw is water activity, Xw and Xs are molar fractions of water and solute, respectively, and K is the correlating constant, has been widely used ...

Engineering Hybrid Extracellular Vesicles for Functional mRNA Delivery

Advanced Functional Materials, EarlyView.
This study optimizes two methods for the generation of extracellular vesicle (EV)‐mimetic‐Lipid Nanoparticle (LNP) (CELLNPs) and EV‐LNP (HEVs) hybrid nanoparticles for messenger (mRNA) delivery. The authors screen lipid compositions to maximize hybrid nanoparticle formation and analyze the resulting nanoparticles with single particle characterization ...

Composites of Shellac and Silver Nanowires as Flexible, Biobased, and Corrosion‐Resistant Transparent Conductive Electrodes

Advanced Functional Materials, EarlyView.
Shellac, a centuries‐old natural resin, is reimagined as a green material for flexible electronics. When combined with silver nanowires, shellac films deliver transparency, conductivity, and stability against humidity. These results position shellac as a sustainable alternative to synthetic polymers for transparent conductors in next‐generation ...
