High‐throughput production of high‐temperature capacitor films is realized by Qi Li, Jinliang He, Qing Wang, and co‐workers in article number https://doi.org/10.1002/adma.201805672 through fast and continuous deposition of a nanoscale thin layer of an insulating barrier using atmospheric‐pressure plasma‐enhanced chemical vapor deposition. This approach should be adaptable to the industrial extrusion method for highly productive manufacturing of capacitor films.

The limitations of conventional pesticides have raised the demand for innovative and sustainable solutions for plant protection. RNA Interference (RNAi) triggered by dsRNA has evolved as a promising strategy to control insects in a species-specific manner. In this context, we review the methods for mass production of dsRNA, the approaches of exogenous application of dsRNA in the field, and the fate of dsRNA after application. Additionally, we describe the opportunities and challenges of using nanoparticles as dsRNA carriers to control insects. Furthermore, we provide future directions to improve pest management efficiency by utilizing the synergistic effects of multiple target genes. Meanwhile, the establishment of a standardized framework for assessment and regulatory consensus is critical to the commercialization of RNA pesticides.

A high-sensitivity and high-spatial-resolution distributed acoustic sensor based on phase-sensitive optical frequency domain reflectometry ( Φ -OFDR) is proposed. The vibration information is retrieved from the phase change of the complex Rayleigh backscattering. Inner-pulse division and rotating-vector-sum methods are employed to overcome the fading problem and to suppress the crosstalk along the fiber. For the first time, to the best of our knowledge, the waveforms of two simultaneous kilohertz-level vibrations along a 950 m fiber are recovered thanks to the enhanced crosstalk suppression ratio. The spatial resolution of 12 cm and strain resolution of 1 n ε / H z are experimentally achieved.
