Three-dimensional (3D) ordered porous carbon is generally believed to be a promising electromagnetic wave (EMW) absorbing material. However, most research works targeted performance improvement of 3D carbon, and the specific attenuation mechanism still ambiguous. Therefore, in this work, novel ultra-light egg-derived foam (EDCF) structure has been successfully constructed by simple carbonization combined with silica microsphere template-etching process. Based on an equivalent substitute...
Herein, the redox-reversible stability of a perovskite type SFMNi cathode decorated with <italic>in situ</italic> exsolved Ni–Fe alloy nanoparticles is investigated using experimental results and explained by exsolution–redissolution model.
The BeiDou navigation satellite system (BDS) currently has 41 satellites in orbits and will reach its full constellation following the launch of last BDS June 2020 to provide navigation, positioning, timing (PNT) services for global users. In this contribution, we investigate characteristics inter-system bias (ISB) between BDS-2 BDS-3 verify whether an additional ISB parameter should be introduced precise point positioning (PPP). results reveal that because different clock references applied...
Microfluidics has demonstrated significant potential for advancing biomedical research. However, the widespread adoption of current microfluidic devices within community is hindered by two major challenges: standardization and throughput. To address these issues, emerging micro-/millifluidic plates based on microtiter plate format have been proposed. On one hand, established standards facilitate clear communication between engineers end-users, enabling untrained users to manipulate directly...
Three new dioxopiperazine metabolites (1–3), together with two known compounds, N-acetyltyramine (4) and cyclo-(Ala-Val) (5), were isolated from a marine-derived fungus Aspergillus fumigatus Fres. Their structures established by spectroscopic methods. cytotoxic activities against the K562 cell line preliminarily evaluated sulphorhodamine B (SRB) method.
A bilayer Zr0.84Y0.16O1.92-La0.8Sr0.2Cr0.5Fe0.5O3-δ (YSZ-LSCrF) dual-phase membrane with a hierarchical structure is successfully prepared for reactor application by the freeze-drying tape-casting method. The oxygen permeation flux of extremely enhanced from 0.001 32 to 0.0165 mol m–2 s–1 at 950 °C under an air/CO gradient, which attributed effectively decreased gas diffusion resistance in support as well significantly lowered ion functional layer. superior permeability and stability enable...
Multi-frequency and multi-GNSS integration is currently becoming an important trend in the development of satellite navigation positioning technology. In this paper, GPS/Galileo/BeiDou (BDS) precise point (PPP) with ambiguity resolution (AR) are discussed detail. The mathematical model triple-system PPP AR principle fractional cycle bias (FCB) estimation firstly described. With data 160 stations Multi-GNSS Experiment (MGEX) from day year (DOY) 321-350, 2018, FCBs three systems estimated...
It is difficult to enable traditional precise point positioning (PPP) with ambiguity resolution (AR) due fractional cycle biases (FCBs), which limit the accuracy and reliability of results. The BeiDou Navigation Satellite System (BDS) has been providing continuous positioning, navigation, timing (PNT) services in global region since end 2018. BDS constellation includes geostationary earth orbit (GEO), inclined (IGSO), medium (MEO) satellites. However, its hybrid structure satellite-side...
As one of the main error sources in high-precision Global Positioning System (GPS) data processing, higher-order ionospheric (HOI) delays cause significant effects on coordinate time series that cannot be ignored analyses long series. Typically two geomagnetic models, DIPOLE model and International Geomagnetic Reference Field (IGRF) model, are used for calculating HOI corrections. This paper investigates correction caused by GPS from 104 globally distributed GNSS Service (IGS) stations...
Slewing bearings are the basic structural components widely used in construction machinery industry. Their stress status and distribution have great influence on service life. A finite element approach for a single-row slewing bearing is established based bilinear isotropic model. The at different loading conditions simulated with geometric material parameters. result shows that numerical simulation reasonable comparison analytical obtained by Hertz’s theory provides reliable design...
