Materials and Wireless Microfluidic Systems for Electronics Capable of Chemical Dissolution on Demand (Adv. Funct. Mater. 92015)

Developing a polymeric semiconductor photocatalyst with visible light response.

A facile strategy based on the amidation reaction of anhydride and NH(2) group in carbon nitride polymer is developed to synthesize a new polymeric photocatalyst which responds to visible-light. The high photocatalytic activity may be due to the coupling anhydride groups promoting the separation of the photoinduced electrons and holes.

Visible light-driven pure water splitting by a nature-inspired organic semiconductor-based system.

For the first time, it is demonstrated that the robust organic semiconductor g-C3N4 can be integrated into a nature-inspired water splitting system, analogous to PSII and PSI in natural photosynthesis. Two parallel systems have been developed for overall water splitting under visible light involving graphitic carbon nitride with two different metal oxides, BiVO4 and WO3. Consequently, both hydr...

Metamaterials: Snapping Mechanical Metamaterials under Tension (Adv. Mater. 39/2015).

By exploiting snap-through instabilities, D. Pasini and co-workers design a damage-tolerant mechanical metamaterial that snaps sequentially under tension, thereby accommodating a very large deformation up to 150%. On page 5931, they describe how the nonlinear mechanical response of the metamaterial can be robustly programmed by tuning the architecture of its unit cell.
