Wavelength‐Dependent 3D Printing: Introducing 3D Printed Action Plots

Advanced Materials, EarlyView.
Photochemical action plots – wavelength‐dependent reactivity studies of photoactive molecules – can show a significant mismatch between the peak of photochemical action and maximum absorbance in photopolymerization systems in solution. How this knowledge translates to photocuring in light‐driven 3D printing remains unexplored.

Light‐Programmable Interfaces: From Molecular Photoswitching to Adaptive Membrane Separations

Advanced Materials Interfaces, EarlyView.
This review advances an interface‐centered framework for light‐responsive membranes, linking molecular photoswitches (azobenzene (AZO), spiropyran (SP), diarylethene (DAE), donor–acceptor Stenhouse adducts (DASA), photoacid) to integration strategies in polymeric, porous, self‐assembled, and mixed‐matrix systems.

On the abundance of non-cometary HCN on Jupiter

, 2010
Using one-dimensional thermochemical/photochemical kinetics and transport models, we examine the chemistry of nitrogen-bearing species in the Jovian troposphere in an attempt to explain the low observational upper limit for HCN.
