  • montage of mechanical metamaterials micrograph and drawing

    Editors from journals across the Nature Portfolio are delighted to present this collection of research and reviews published over the past two years on the science and technology of mechanical metamaterials.


  • Kasidit Toprasertpong and colleagues describe reservoir computing hardware with potential for on-chip integration with existing computing technologies. The approach is based on a ferroelectric field-effect transistor, and can solve computational tasks on time series data including nonlinear time series prediction after training with simple regression.

  • Yu and colleagues report a modified and flexible Evans-Perkins heat pump cycle integrating heat recovery and storage and demonstrate its application in a prototype heat pump. The recovered heat can be used as an ancillary heat source for the heat pump’s operation and to defrost the heat pump evaporator as necessary.

  • Shaoyan Zhang and colleagues describe a combined all-optical ultrasound imaging and laser ablation tool. The device, less than 1mm in diameter, enables ablation and simultaneous real-time ablation monitoring of tissue at the mm scale. The device could be used for minimally invasive surgical applications.

  • Nidhi Sinha, Haowen Yang and colleagues report a microfluidic large-scale integration chip to probe temporal single-cell signalling networks via the delivery of patterns of input signalling molecules. The researchers use their device to investigate drug-induced cancer cell apoptosis and single cell transcription (STAT-1) protein signalling dynamics.

  • Xumin Gao and colleagues report a robust and waterproof monolithic GaN optoelectronic chip that integrates an energy harvester, light emitting diode and Bragg reflector. The units transform external light into electrical energy and directly activate the integrated LEDs even when attached to freely swimming Carassius auratus fish.

    • Space bioprocess engineering integrates synthetic biology and bioprocess engineering with the specific goal to support human life in long term space missions. In this Perspective, Berliner and colleagues describe a pathway towards the development and implementation of space bioprocessing technologies of the future.

  • A recent publication in Environmental Sciences Advances reports flame-retardant, colored and soil-biodegradable nanocellulose bioleather with tensile strength and ductility competitive with traditional leather. Further, the researchers report that these microbial biotextiles have a thousandfold reduction in human toxicity levels compared to cow leather with a carbon footprint lower than cow leather, synthetic leather and cotton.

  • A chemical strategy to separate troublesome americium from lanthanides could help reduce the radiological hazards of spent nuclear fuel and create opportunities for waste re-processing.

    • Mengying Su

  • Findings from a recent publication in Energy and Buildings show that “net-zero energy” renovations can lead to net-positive energy buildings. But the results also raise concerns for the energy grid and overheating in the summer. The analysis of energy consumption of residential buildings give insight into future performance of a Dutch neighborhood’s deep energy-saving refurbishments.
