Bioinspired Fern-like FeO Functionalized with Pd/PdO Nanoparticles for High-Performance Acetone Sensing.

The accurate monitoring and detection of acetone vapor are essential for environmental and human safety. Consequently, fern-like FeO with hierarchical vein-like structures is synthesized via a concise hydrothermal method. Compared with pure fern-like FeO, fern-like Pd/PdO-FeO shows the best acetone-sensing characteristics, in terms of lower operating temperature (180 °C), better selectivity and excellent long-term stability.

Excellent Photonic and Mechanical Properties of Macromorphic Fibers Formed by Eu-Complex-Anchored, Unzipped, Multiwalled Carbon Nanotubes.

The macromorphic properties of carbon nanotubes perform poorly because of their size limitations: nanosize in diameters and microsize in length. In this work, to realize these dual purposes, we first used an electrochemical method to tear the surface of multiwalled carbon nanotubes (MWCNTs) to anchor photonic Eu-complexes there. Through the polar reactive groups endowed by the tearing, the Eu-complexes coordinate at the defected structures, obtaining the Eu-complex-anchored, unzipped, multiwalled carbon nanotubes (E-uMWCNTs).
