C-coupled hydroxylated g-C 3 N 4 was fabricated via a facile method for efficient photocatalytic hydrogen evolution.
The seasonal variation of land cover and the large deformation gradients in coal mining areas often give rise to severe temporal geometrical decorrelation interferometric synthetic aperture radar (InSAR) interferograms. Consequently, it is common that available InSAR pairs do not entire time period SAR acquisitions, i.e., gaps exist multi-temporal observations. In this case, very difficult accurately estimate mining-induced dynamic subsidence using traditional time-series techniques....
Abstract This paper presents a novel method to estimate active layer thickness (ALT) over permafrost based on InSAR (Interferometric Synthetic Aperture Radar) observation and the heat transfer model of soils. The time lags between periodic feature InSAR-observed surface deformation meteorologically recorded temperatures are assumed be intervals that temperature maximum diffuse from ground downward bottom layer. By exploiting one-dimensional soils, we ALTs. Using frozen soil region in...
Abstract The May 22nd, 2021, 7.4 Maduo earthquake occurred on an intraplate fault of Bayan‐Har block in the Tibet Plateau. Here, we derive coseismic and early postseismic surface deformations from Sentinel‐1 (S1) interferometric synthetic aperture radar (InSAR) data. We use subpixel offsets SAR Sentinel‐2 (S2) optical images to determine rupture traces. geometry slip distribution multi‐segmented ruptures are estimated by inverting InSAR interferograms pixel offsets. show that at least five...
Abstract On 22nd May 2021 (local time), an earthquake of M s 7.4 struck Maduo county in Qinghai Province, China. This was the largest China since 2008 Wenchuan earthquake. In this study, ascending/descending Sentinel-1 and advanced land observation satellite-2 (ALOS-2) synthetic aperture radar (SAR) images were used to derive three-dimensional (3-D) coseismic displacements We differential interferometric SAR (InSAR, DInSAR), pixel offset-tracking (POT), multiple InSAR (MAI), burst overlap...
The 8 January 2022 Mw6.7 Menyuan earthquake was generated in the transition zone between western Lenglongling fault and eastern Tuolaishan fault, both being part of Qilian–Haiyuan system with an important role adjustment regional tectonic regime. In this study, four pairs SAR (synthetic aperture radar) data from Sentinel-1 ALOS-2 (Advanced Land Observation Satellite-2) satellites were used to derive surface displacement observations along satellite line-of-sight (LOS) azimuth directions...
Abstract Complete three‐dimensional (3‐D) movements of slow‐moving landslides are critical to enhancing the understanding landslide mechanism. Multi‐source synthetic aperture radar (SAR) observations provide an opportunity derive 3‐D movements. However, deriving complete faces potential challenges incoherent phases and ill‐posed inverse problem, which may result in incomplete inaccurate results, especially for slopes facing north/south. Here, we propose a topography‐constrained strain model,...
Pressure-stabilized high-entropy sulfide (FeCoNiCuRu)S2 (HES) is proposed as an anode material for fast and long-term stable lithium/sodium storage performance (over 85% retention after 15 000 cycles @10 A g-1 ). Its superior electrochemical strongly related to the increased electrical conductivity slow diffusion characteristics of entropy-stabilized HES. The reversible conversion reaction mechanism, investigated by ex-situ XRD, XPS, TEM, NMR, further confirms stability host matrix HES...
Against the backdrop of global warming and increased rainfall, hazards potential risks landslides are increasing. The rapid generation a landslide inventory is great significance for disaster prevention reduction. Deep learning has been widely applied in identification due to its advantages terms deeper model structure, high efficiency, accuracy. This article first provides an overview deep technology basic principles, as well current status remote sensing databases. Then, classic...
Orbital errors, characterized typically as longwavelength artifacts, commonly exist in interferometric synthetic aperture radar (InSAR) imagery a result of inaccurate determination the sensor state vector. errors degrade precision multitemporal InSAR products (i.e., ground deformation). Although research on orbital error reduction has been ongoing for nearly two decades and several algorithms reducing effect are already existence, cannot always be corrected efficiently reliably. We propose...
