Photo‐Switchable Molecular Module Programming PET Biodegradation in Aquatic Environments

Advanced 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.

Electron‐Deficient Linkers Enhance H2O2 Electrosynthesis in Covalent Organic Frameworks

Advanced Functional Materials, EarlyView.
Linker π‐conjugation modulates the electronic state of the Ni–N4 centers and their interaction with the key *OOH intermediate while preserving the primary coordination motif. NiPc‐PTDA delivers an H2O2 selectivity of 92% and a production rate of 34.8 mol gcat−1 h−1, highlighting linker electronic properties as a molecular design parameter for NiPc ...

Structure of porous Vycor glass

Physical Review A, 1987
Small-angle neutron scattering experiments investigating the structure of porous Vycor glass are reported. The long-wave-length behavior ($0.004{\AA{}}^{\ensuremath{-}1}\ensuremath{\le}q\ensuremath{\le}0.025{\AA{}}^{\ensuremath{-}1}$) of the measured structure factor $S(q)$ is in good agreement with Cahn's prediction for spinodal decomposition.

Porous Gold Structures Templated by Porous Silicon

Journal of The Electrochemical Society, 2008
In this work, we describe the synthesis of porous Au structures by galvanic displacement reaction using porous Si exhibiting arrays of parallel pores with diameters near 100 nm as template material. Two metal ions were used as Au precursors: tetrachloroaurate(III) and bis(ethylenediamine)Au(III). Fluoride was employed to etch the Si oxides that form as
