Launched on 5 June 2019, the BuFeng-1 A/B twin satellites were part of first Chinese global navigation satellite system reflectometry (GNSS-R) mission. In this letter, a brief introduction BF-1 mission and its preliminary results sea surface wind retrieval are presented. Empirical fully developed (FDS) geophysical model functions (GMFs) relating normalized bistatic radar cross-section to speed proposed for GNSS-R instruments. The FDS GMFs derived from collocated observations, European Center...
Ru(H2dcbpy)32+, one of the Ru(bpy)32+ (dcbpy = 2,2′-bipyridine-4,4′-dicarboxylic acid, bpy 2,2′-bipyridine) derivatves, has been used as a propeller-like photoactive metalloligand to coordinate with indium(III) ions form highly symmetric metal–organic framework [InRu(dcbpy)3][(CH3)2NH2]·6H2O (1), and cubic microcrystals 1 have acquired through modified procedures. Compound manifests broad visible light absorption band strong red emission long decay lifetime, both which are originated from...
Enantiopure (S)-1-(4-methoxyphenyl) ethanol {(S)-MOPE} can be employed as an important synthon for the synthesis of cycloalkyl [b] indoles with treatment function general allergic response. To date, biocatalytic resolution racemic MOPE through asymmetric oxidation in biphasic system has remained largely unexplored. Additionally, deep eutectic solvents (DESs), a new class promising green solvents, have recently gained increasing attention biocatalysis their excellent properties and many...
Abstract Background Biocatalytic asymmetric reductions with whole cells can offer high enantioselectivity, environmentally benign processes and energy-effective operations thus are of great interest. The application cell-mediated bioreduction is often restricted if substrate product have low water solubility and/or toxicity to the biocatalyst. Many studies shown that a biphasic system useful in this instance. Hence, we developed efficient reaction systems biocompatible water-immiscible ionic...
A new land surface clustering algorithm is developed to retrieve soil moisture (SM) using the Global Navigation Satellite System reflectometry (GNSS-R) technique. Data from BuFeng-1 (BF-1) twin satellites A/B, a pilot mission for Chinese GNSS-R constellation, used SM retrieval. The core concept of cluster global areas into different types according properties and calculate type by type, based on linear relationship between equivalent specular reflectivity (ESR) SM. comparison results product...
Real-time location system (RLS) based on RFID is an effective indoor positioning system. The battery-free and low cost UHF passive tags can be attached almost any objects, which are recognized as the best medium to achieve high precision ranging for large-scale objects. This paper proposes range measurement multifrequency phase difference of arrival (MF-PDoA) using discusses principle, experiment implementation, results evaluation in detail. After a theoretical overview MF-PDoA it introduces...
The water‐stable 3D lanthanide‐organic framework ( Ln ‐MOF) {[Eu(bci)(H 2 O)] · 2H O} n 1 ) [H bci = bis(2‐carboxyethyl)isocyanurate] was synthesized under hydrothermal conditions. Compound ‐ Eu exhibits a open‐framework connected by Eu–(μ‐O) –Eu chains and ligands. Meanwhile, highly efficient luminescent sensing for environmentally relevant Fe 3+ SCN – ions through luminescence quenching. These results indicated that it could be utilized as multi‐responsive sensor.
Under the λ≥420 nm visible light illumination, Pt4+ ions exchanged LTA zeolite powders without further heat-treatment presented H2 evolution at a rate of 5 μl/(15 mgh) via photocatalysis water splitting. It was shown that efficiency generation by higher than counterpart samples with heat treatment. In addition, lower Pt loading concentration showed those did. The can be attributed to effective isolation molecules and atomic or few atom 'cluster' scale zeolite's periodical porous structure,...
Global Navigation Satellite System can not only positioning but also emit microwaves of L band to the earth surface. With reflection signals, we obtain information about sea The Delay Doppler Map calculated from received power recently play a key role in building relationships with surface parameters. In this paper, basics Delay-Doppler are introduced and conducted by employing set new released TechDemoSat-1 GNSS-R data. addition, parameters retrieved using Maps presented as prospect.
Oil spill detection plays an important role in marine environment protection. The technique of global navigation satellite system-reflectometry (GNSS-R) has the advantage a short revisit time, which could help with timely cleanup oil pollution. conventional GNSS-R algorithm can resolve only dielectric constant based on power ratio measurements, while that water cannot be realized. This is because much larger than such range equation used inadequate. To this problem, we proposed new...
