Electromagnetic Reconfiguration Using Stretchable Mechanical Metamaterials.

Response to environmental thermomechanical inputs in applications that range from wearable electronics to aerospace structures necessitates agile communication systems driven by reconfigurable electromagnetic structures. Antennas in these systems must dynamically preserve acceptable radiation characteristics while enabling on-demand performance reconfiguration. However, existing reconfiguration mechanisms through stretchable conductors rely on high-strain behavior in soft substrates, which limits their applicability.

Yolk-shell-type CaO-based sorbents for CO capture: assessing the role of nanostructuring for the stabilization of the cyclic CO uptake.

Improving the cyclic CO uptake stability of CaO-based solid sorbents can provide a means to lower CO capture costs. Here, we develop nanostructured yolk(CaO)-shell(ZrO) sorbents with a high cyclic CO uptake stability which outperform benchmark CaO nanoparticles after 20 cycles (0.17 g g) by more than 250% (0.
