Moiré materials are a versatile and tunable platform that offers a wide variety of lattice constants, energy scales and symmetries, leading to a rich interplay of electron correlations and topology. This Review summarizes recent breakthroughs in topological and Berry physics in moiré materials.
Solid-state lithium metal batteries have the potential to meet energy density and safety requirements that current commercial Li-ion batteries cannot. Given their solid-state components, these batteries are subject to — and strongly affected by — external pressure during their manufacturing and operation. This Review examines the relationship between external pressure and electrochemical behaviour in these batteries.
The organic electrochemical transistor (OECT), with its organic mixed ionic–electronic conductor (OMIEC) channel, serves as an amplifying transducer of biological signals. This Review highlights OMIEC design milestones and illustrates how incorporating specific properties into OMIECs can extend OECT applications beyond biosensing.
