Modeling photonic crystal fibers

open access: yesAdvances in Applied Mathematics, 2006
The problem indicated in the title gives rise to a Maxwell problem. However, looking for guided waves in the \(x_3\)-direction and assuming the medium to be \(x_3\)-independent, the author is left with two scalar problems with periodic coefficients. The corresponding Green integral operators and their spectral properties are used for a characterization

Photo‐Switchable Molecular Module Programming PET Biodegradation in Aquatic Environments

open access: yesAdvanced Functional Materials, EarlyView.
We address the plastic durability paradox by integrating an itaconic acid–derived pyrrolidone module into polymer backbones. Sunlight in water triggers Norrish Type I ring‐opening and hydrophilization, enabling rapid biodegradation into nontoxic minerals.
