This work presents the development and systematic study of a method to prepare hierarchical titanium silicalite-1 (TS-1) zeolites with high tetra-coordinated framework Ti species content. The new involves (i) synthesis aged dry gel by treating zeolite precursor at 90 °C for 24 h; (ii) TS-1 using tetrapropylammonium hydroxide (TPAOH) solution under hydrothermal conditions. Systematic studies were conducted understand effect conditions (including TPAOH concentration, liquid-to-solid ratio,...
In recent years, concern has increased about the depletion of marine resources caused by overexploitation fisheries and degradation ecosystems. The Automatic Identification System (AIS) is a powerful tool increasingly used for monitoring fishing activity. this paper, identification type vessel (trawlers, gillnetters seiners) was carried out using 150 million AIS tracking points in April, June September 2018 northern South China Sea (SCS). vessels’ spatial temporal distribution, duration time...
Ethyl lactate is a promising green solvent, which can be produced via esterification of biomass derived lactic acid and ethanol. Herein, we report the development highly active stable polyoxometalates (POMs) supported on zeolite catalysts for synthesis ethyl lactate. Repetitive stability tests were performed using developed catalysts, comparative characterization fresh used was to understand changes in physicochemical properties catalysts. It found that low-silica Y zeolites...
The technology of retrieving sea surface wind field from spaceborne synthetic aperture radar (SAR) is increasingly mature. However, the retrieval related to precipitation effect still facing challenges, especially strong extreme weather such as tropical cyclone will cause speed error exceed 10 m/s. Semantic segmentation and weak supervision methods have been used for SAR rainfall recognition, but not accurate enough support correction retrieval. In this article, we propose use deep learning...
With the development of deep learning (DL), research on ship classification in synthetic aperture radar (SAR) images has made remarkable progress. However, such primarily focused classifying large ships with distinct features, as cargo ships, containers, and tankers. The SAR fishing vessels is extremely challenging because two main reasons: 1) small size minor interclass differences make fine-grained features difficult, 2) determining vessel types resulting a lack labeled data. Hence, after...
Selective synthesis of lactic acid from bioderived substrates still remains a grand challenge. We reported series unique bimetallic Pt–Co/CeOx catalysts, prepared by fractional precipitation method. Strong electronic coupling for Pt–Co is found to enhance activity toward dehydrogenation (C–H bond cleavage) glycerol, as evidenced X-ray photoelectron spectroscopy (XPS) and transmission electron microscopy (TEM) studies the catalysts. Detectable electroaffinity PtCo trends gain electrons CeOx...
Abstract Mesoporous Y zeolites were prepared by the sequential chemical dealumination (using chelating agents such as ethylenediaminetetraacetic acid, H 4 EDTA, and citric acid aqueous solutions) alkaline desilication sodium hydroxide, NaOH, treatments. Specifically, ultrasound-assisted treatment (i.e., ultrasonic treatment) was proposed alternative to conventional treatments which are performed under hydrothermal conditions. In comparison with treatment, showed comparatively enhanced...
