Bye bye palladium. Kai A. I. Zhang and coworkers develope a palladium-free and photocatalytic Stille-type coupling reaction of aryl iodides and aryl stannanes by a conjugated micro porous polymer-based photocatalyst under visible light irradiation at room temperature in article number 1700101. Via the aryl radical-mediated reaction pathway, the light-promoted coupling reaction using a pure orga...

In article number 1600394, Almira Kurbangalieva, Katsunori Tanaka, and co-workers at the RIKEN Biofunctional Synthetic Chemistry Laboratory develop a way to engineer glycan complexes— heterogeneous clusters of sugar chains attached to proteins or lipids—in a way that allows the molecules to be transported preferentially to specific organs of the body through pattern recognition mechanisms, depe...

Cheng-Wei Qiu, Tie Jun Cui, and co-workers present an all-dielectric semispherical lens with functions in shaping 3D wave-propagation paths in article 1600022. The cover image shows principle of the 3D superresolution imaging system, which includes a semispherical magnifying meta-lens and a planar focusing lens. The semispherical lens magnifies signals of the objects located at the core of lens...

Cyrille Boyer, May Lim, and co-workers highlight recent advances in upconversion nanoparticles (UCNPs) as NIR-initiated controlled drug delivery systems. Surface modification strategies are reviewed alongside with the influence of the laser power intensity and illumination time on the drug release pattern in article 1500437. NIRto-UV/visible UCNPs have emerged as potential remotecontrolled nano...
