ABSTRACT Environmental pollution has become a major health concern and escalated to political issue in China. It been identified that enforcement of environmental regulation is the weakest link protection. Local government often focus study because its legal obligation for under national law, significance complex intriguing central–local relations Chinese system. We propose an interpretative framework explain local dilemma China, based on institutional approach. governments tend...
Abstract Cascaded metasurfaces can exhibit powerful dynamic light manipulation by mechanically tuning the far‐field interactions in layers. However, most current designs, are separated gaps smaller than a wavelength to form total phase profile, representing direct accumulation of profiles each layer. Such small gap sizes may not only conflict with conditions but also pose great difficulties for practical implementations. To overcome this limitation, design paradigm taking advantage...
The rapid development of flexible electronics necessitates simplified processes that integrate heterogeneous materials and structures. In this study, laser engraving is combined with electrochemical deposition (ECD) to directly fabricate various micro/nano-structured components electronic circuits.

Proton exchange membrane fuel cells (PEMFCs) should further reduce the platinum consumption to lower their manufacturing costs and life-cycle carbon emissions. However, performance of catalyst layers with low-Pt loading needs be improved. Short-side-chain (SSC) ionomers have been proven enhance catalytic activity conventional layers. In this work, SSC ionomer was applied electrospun layer, achieved a remarkable improvement in performance. With use commercially available catalyst, electrode...

WiFi energy harvesting is a promising solution for powering microsensors and microsystems through collecting electromagnetic (EM) energies that exist everywhere in modern daily lives. In order to harvest EM energy, we proposed metamaterial-inspired antenna (MIA) based on the resonant magnetic dipole operating bands.

Abstract Directional radiofrequency (RF) sensing, also known as radio direction finding, is essential in various applications that involve localizing RF sources. However, existing sensing technologies face challenges due to their large antenna sizes and complex signal processing circuits, which hinder the realization of miniaturized subwavelength sensors.
