Resolving the Cu(bdc) Conundrum: Identifying Non‐Porous Packing of Prototypical Coordination‐Network Thin Films Combining Advanced Diffraction Techniques and Computational Modelling

Advanced Functional Materials, EarlyView.
Solution‐processed Cu(bdc) forms prototypical MOF thin films for which a multitude of not fully satisfactory structural models have been suggested. Combining rotating grazing‐incidence diffraction and X‐ray reflectivity on two complementary samples with density‐functional theory, we first discard the previously suggested models and then identify a non ...

Engineering Pendant Group Chemistry to Control Hydrophilicity and Oxidative Degradation of Thioketal‐Based Biomaterials

Advanced Functional Materials, EarlyView.
Thioketal (TK) polymers are promising biomaterials due to their selective biodegradation by reactive oxygen species (ROS), but they respond slowly to physiologic doses of ROS. Here, the TK bond's pendant groups are modified to enhance the degradation of TK‐based implants both in vitro and in vivo.

Optical network architectures for dynamic reconfiguration of full duplex, multiwavelength, radio over fiber

, 2006
In recent years there have been rapid advances in the techniques to generate and transport radio signals over optical fiber, but very little has been done to date to develop the concept of a full duplex, multiwavelength, radio-over-fiber network ...

Invisible Polymer Walls Enhance Reorientational Optical Nonlinearity in Oligothiophene‐Doped Liquid Crystals

Advanced Functional Materials, EarlyView.
The polymer wall stabilized dye‐doped liquid crystals (PWLCs) enhance the sensitivity of photoinduced molecular reorientation in dye‐doped LC systems. The PWLC with an invisible polymer wall successfully reduces the threshold intensity and functions as an optical limiter under the incidence of low intensity light laser source.
