This Perspective provides an overview on the emergent field of colloidal robotics, discussing recent developments on colloidal and micrometre-sized particles that can perform functions such as sensing, communication, computation and motion.
The commercialization of electronic textile (e-textile) products requires balanced sustainability considerations. Here the authors propose an e-textile design framework involving repair, recycle, replacement and reduction that can unify environmental friendliness, market viability, supply-chain resilience and user experience quality.
It is imperative that sustainability issues are considered throughout the life cycle of modern organic electronic devices. Here McCulloch and colleagues evaluate the status of embedded carbon, options for more sustainable materials, and recycling solutions both during manufacturing and at the end of life in organic electronic products.
Nanoscale ferroelectric topological solitons, such as polar bubbles, polar bubble skyrmions and hopfions, have garnered immense interest due to their emergent properties. This Perspective discusses how these structures form, advances in their study and how they can enable new devices and physics.
The discovery of ferroelectric switching in ultrathin layers of hafnium dioxide has aroused significant interest for low-power non-volatile memory technologies. This Perspective discusses how lessons learned from hafnium dioxide-based ferroelectrics can be applied to other applications, and other binary oxides.
Colloidal nanocrystals can form into periodic superlattices exhibiting collective vibrations from the correlated motion of the nanocrystals. This Perspective discusses such collective vibrations and their as-of-yet untapped potential applications for phononic crystals, acoustic metamaterials and optomechanical systems.
Research on two-dimensional van der Waals ferroelectrics has witnessed an explosion over the past few years. This Perspective formulates a framework by which results can be analysed, reviews recent progress, discusses mechanisms and properties for applications, and outlines challenges to be addressed.
