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.

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.

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.

Architected materials are a class of materials with structures intermediate in scale between atomic arrangement and bulk dimensions; this additional degree of freedom enables unique properties and functionalities. This Review describes the state of the art in architected materials that are responsive to various stimuli.

Engineers have long sought to fabricate vascular networks to deliver oxygen and nutrients within engineered human tissues for regenerative medicine applications. This Review highlights how materials advances have enabled the development of vascular engineering approaches driven by both technology and nature.

2D materials hold promise as inks for printed technologies. This Review discusses ink formulation processes, from materials selection and deposition techniques to applications, and the perspectives for the commercialization of printed devices.

This Perspective compares the attributes of nanoparticles versus microparticles as the active electrode material in lithium-ion batteries. We propose that active material particles used in future batteries should be inherently multiscale to capture the best of both worlds.
