An article in Advanced Materials presents polymer donors with hydrogen-bonding spacers that enable intrinsically stretchable organic solar cells with a high power conversion efficiency and good stretchability.
An article in the Journal of the American Chemical Society reports azobenzene crystals that roll continuously under visible light, thanks to crystal packing effects that shift azobenzene’s light-responsive window.
An article in Nature Catalysis presents a computationally guided optimization of iron-based cathodes for protonic ceramic fuel cells that led to the fabrication of devices with good efficiency and stability.
Rationally creating an intense colorant has been a challenge for centuries. Serendipity often played a role in the discovery of important pigments and dyes. In particular, inorganic pigments are promising because of their durability under different conditions. However, in spite of recent advancements in quantum mechanical theories and computational methods, predicting a crystal lattice that will produce an intense inorganic pigment of a desired colour is still elusive.
Electronic waste, with printed circuit boards (PCBs) at its heart, is the fastest-growing category of hazardous solid waste in the world. New materials, in particular biobased materials, show great promise in solving some of the sustainability and toxicity problems associated with PCBs, although several challenges still prevent their practical application.
Thanks to the lifespan and efficiency benchmarks set by the current generation of white light-emitting diodes (WLEDs), the lighting industry is quickly replacing traditional LEDs that use monochromatic light. Building upon research advances in framework solids for WLEDs and capitalizing on their bottom-up design principles, modular crystalline hybrids are paving paths to energy-efficient lighting alternatives.
We popularize scientific topics through the 26-episode film series Science in the City, which depicts the perception of science in Africa. We campaign in African schools, universities and public events to initiate debates on science, inviting actors and scientists to engage with audiences.
The ability to communicate clearly is an essential skill for scientists, but it is rarely taught. Katie Yurkewicz, Head of Scientific and Technical Communications at Argonne National Laboratory, shares three steps to follow to captivate an audience and craft a compelling narrative for any topic or medium.
An article in Advanced Materials reports biosensor arrays based on a field-effect transistor that can identify bladder cancer with high accuracy from untreated urine samples.
An article in Angewandte Chemie International Edition discovers a pair of colloidal semiconductor magic-size clusters that can isomerize through either a direct and intra-cluster pathway or an indirect and inter-cluster pathway.
A manuscript in Advanced Materials reports a strategy to use electrode design to control the formation of the conduction channels in memristors, improving their reliability.
An article in Nature Communications combines electron diffraction and hierarchical cluster analysis to determine the precise, atom-level structure of covalent organic frameworks.
