With the launches of HY-2B, HY-2C and HY-2D, National Satellite Ocean Application Service (NSOAS) successfully established first batch HY-2 constellation on 19 May 2021, dedicated to detecting marine dynamic environment. While validation calibration series satellites have been well studied, using both in situ cross-track measurements, further evaluation is required mapping capability mesoscale ...

Advances in biomimetic three-dimensional (3D) melanoma models have brought new prospects of drug screening and disease modeling, since their physiological relevancy for recapitulating vivo tumor architectures is more accurate than traditional two-dimensional (2D) cell culture. Gelatin methacryloyl (GelMA) widely used as a tissue-engineered scaffold hydrogel 3D In the present study, an vitro mal...

The goal of this report is i) to model the occurrence and hunting yield (HY) density wild ungulates not only for widely distributed species in Europe, but also those ones which have a constrained distribution ii) compare output with observed HY. Random Forest function was used modelling species. We data available from past 30 years, HY (period 2015-2020) records collected by ENETWILD. Like prev...

Copper-exchanged faujasite (Cu-FAU) zeolites have been investigated in this work as promising adsorbent materials to further purify hydrogen produced via ammonia decomposition a membrane reactor. Samples prepared ion-exchange procedure using commercially available NaY, HY and 13X their performance was evaluated compared the one of parent zeolites. The introduction copper species framework demon...

In this paper, the utilisation of zeolites synthesised from fly ash (FA) and related co-disposal filtrates as low-cost adsorbent material were investigated. When raw FA and co-disposal filtrates were subjected to alkaline hydrothermal zeolite synthesis, the zeolites faujasite, sodalite and zeolite A were formed. The synthesised zeolites were explored to establish its ability to remove lead and ...

MFI type zeolite membranes were synthesized on two types of supporting materials, alumina (α-alumina) and yttria-stabilized zirconia (YSZ) coated alumina. Membranes were prepared by template-free secondary growth method with multiple growth steps in order to minimize intercrystalline gaps. Gas permeation characteristics, thermal and hydrothermal stability for MFI type zeolite membranes were exa...

In this study, zeolite was employed for the separation and recovery of P from synthetic wastewater and its use as phosphorus (P) source for the cultivation of the green microalga Chlorella vulgaris and the cyanobacterium Arthrospira (Spirulina) platensis. At P-loaded zeolite concentration of 0.15-1 g/L, in which P was limited, the two species displayed quite different behavior regarding their g...

We present a systematic study to investigate the effects of nonframework cations and the role of phonon scattering mechanisms on the thermal transport properties of zeolite LTA, via experiment and semiempirical lattice dynamics calculations. Our study is motivated by the increasing interest in accurate measurements and mechanistic understanding of the thermal transport properties of zeolite mat...

Hydrophobic Y-zeolite (SiO2/Al2O3 = 810) and TiO2 composite photocatalysts were designed by using two different types of TiO2 precursors, i.e., titanium ammonium oxalate and ammonium hexafluorotitanate. The porous structure, surface property and state of TiO2 were investigated by various characterization techniques. By using an ammonium hexafluorotitanate as a precursor, hydrophobic modificatio...

The studies were carried out on heavy metal bioavailability and leachability during water hyacinth composting mixed with cattle manure, sawdust and natural zeolite. The water hyacinth, cattle manure and sawdust were taken in the 6:3:1 ratio with 5, 10 and 15% natural zeolite and composted for 30 days. The concentrations of nutrients and total heavy metals were increased during the process. Due ...
