Metal-based engineered nanomaterials (MENMs) are increasingly being used in people’s working lives. Although MENMs have important effects on soil ecosystem and play an important role in solving soil environmental problems, the hazards associated with MENMs cannot be ignored. Therefore, more and more scholars have studied the behavior and effects of nanomaterials in soils in recent years. In this review, we explore the articles on MENMs and soil ecosystem retrieved from various databases from 2013 to 2022. We discuss the mechanisms of MENM toxicity, the current state of soil ecosystem, the ecological effects of MENMs on soil microbes, earthworms, and plants, and the ways by which soil organisms take up MENMs. We now know that although MENMs have positive effects on soil ecosystem, their potential hazards are not negligible. Therefore, it is necessary to investigate the effects of MENMs on soil organisms. Meanwhile, we should pay more attention to the negative effects of MENMs on soil ecosystem while exploring their positive effects on soil ecosystem in future research.

Perovskite solar cells(PSCs)with a positive-intrinsicnegative(p–i–n,commonly referred to as“inverted”)structure are becoming commercially attractive due to their superior power conversion efficiency(PCE)and better operational stability as compared to the“normal”structure device.^([1–5])Nonetheless,further improvements in the device performance of inverted PSCs are hampered by interface losses,particularly where the buried interfaces are responsible for perovskite crystallization and chargecarrier extraction.^([6–9])

The infrared microspectroscopy beamline(BL06B) is a phase Ⅱ beamline project at the Shanghai Synchrotron Radiation Facility(SSRF). The construction and optical alignment of BL06B were completed by the end of 2020. By 2021, it became accessible to users. The synchrotron radiation infrared(SRIR) source included edge radiation(ER) and bending magnet radiation(BMR). The extracted angles in the horizontal and vertical directions were 40 and 20 mrad, respectively. The photon flux, spectral resolution, and focused spot size were measured at the BL06B endstation, and the experimental results were consistent with theoretical calculations. SRIR light has a small divergence angle, high brightness, and a wide wavelength range. As a source of IR microscopy, it can easily focus on a diffraction-limited spatial resolution with a high signal-to-noise ratio(SNR). The BL06B endstation can be applied in a wide range of research fields, including materials, chemistry, biology, geophysics, and pharmacology.
