Power semiconductors and power electronics have the potential to support the transition to carbon neutrality. This Review outlines advances in wide-bandgap power devices, converter circuits and power applications, and their potential to reduce carbon emissions from electricity generation, ground transport, data centres and residential heating.

This Review highlights low-power display technologies for a display panel, display electronics and a system, respectively. In principle, static or dynamic power can be reduced through these technologies; however, the reduction is distinct from conventional low-power technologies owing to the unique electro-optical characteristics of displays and specific human visual perception.

Electroactive biomaterials show promise for repairing various tissues through electrical stimulation. This Review examines the design, engineering strategies, clinical applications and challenges for the effective translation of electroactive biomaterials and devices in regenerative medicine.

This Perspective provides an overview of boron nitride research from the perspective of its synthesis, integration and simulation from the material engineering aspects to applications in microelectronics industry.

Traditional DRAM technology, with memory bit cells consisting of one silicon transistor and one capacitor, faces major scaling challenges. A new DRAM bit cell without a capacitor and with two thin-film transistors — each with an oxide semiconductor channel such as indium-gallium-zinc-oxide — shows promises for continuing the DRAM technology roadmap, clearing the way for high-density 3D DRAM.

Bridging the divide between mathematical innovations and real-world applications is essential for addressing global challenges. By fostering interdisciplinary collaboration, diversity and inclusion, we can unlock the full potential of mathematical findings, driving innovation across applied disciplines and delivering mathematical solutions to society’s pressing problems.

Aqueous sulfur-based redox flow batteries (SRFBs) are promising candidates for large-scale energy storage, yet the gap between the required and currently achievable performance has plagued their practical applications. Here, we propose several engineering strategies towards SRFB commercialization.

Autonomous electric vehicles (AEVs) will soon share roads with traditional traffic participants — human-driven vehicles, pedestrians and cyclists — which will require careful planning for safe interactions. Here we advocate for the development of human-like driving technologies for AEVs through human-inspired approaches and the Turing test.
