The fast development of terahertz technologies demands high-performance electromagnetic interference (EMI) shielding materials to create safe environments. Despite tremendous breakthroughs in achieving superb efficiency (SE), conventional have high reflectivity and cannot be re-edited or recycled once formed, resulting detrimental secondary pollution poor adaptability. Herein, a hydrogel-type material incorporating MXene poly(acrylic acid) is fabricated through biomineralization-inspired...
Abstract Developing cost‐effective and high‐performance catalysts for oxygen evolution reaction (OER) is essential to improve the efficiency of electrochemical conversion devices. Unfortunately, current studies greatly depend on empirical exploration ignore inherent relationship between electronic structure catalytic activity, which impedes rational design high‐efficiency OER catalysts.
