(advantageously with Si/AI ratio between 4 and 500) among H+ or NH4+-form of MFI, MEL, FER, MOR, clinoptilolite; introducing P at conditions effective to introduce advantageously at least 0.05 wt% of P; separation of the solid from the liquid if any; an optional washing step or an ...
Phosphorus (P) is an essential nutrient for plant growth and development. Phosphate (Pi) fertilizer supply is an effective way to improve crop yield. However, generally, less than 25% of the applied Pi is taken up by crops. Therefore, it is urgent to improve crop P use efficiency. The o...
In the present work, graphene oxide (GO) was synthesized using pencil lead as a precursor via modified Hummer's method and used for the fabrication of GO-based polylactic acid (PLA) composites with GO concentration variation from 0.25 wt% to 1.25 wt% with a step size of 0.25. The ...

In this work, rheological behavior of ethanol based nanofluids containing three kinds of metal oxide nanoparticles up to 0.15%wt were systematically investigated. All the ethanol-based metal oxide nanofluids were found to show the nonnewtonian behavior over a shear rate range of 50–350 s−1 at...
de Craieye2, Sophia Ng2,3, Mustapha Arkoun1, Claude Plassard4, Mohamadi Faharidine5, Delphine Hourcade5, Francesca Degan5, Sylvain Pluchon1 and Laurent Nussaume2* Abstract Background Inorganic phosphate (Pi) is the sole source of phosphorus for...
6B). The SilE46-128 polypeptide exhibited Ag+-mediated folding similar to the wt SilE whereas the SilE21-98 polypeptide did not exhibit any signs of folding upon Ag+ binding. These data are consistent with a model where a nucleation core is formed by central core motifs 1 and 2 which ...
The wild type (WT) structure of the PInC complex was relaxed in Cartesian space using the Rosetta FastRelax protocol. Mutations were then introduced and the FastRelax protocol used to repack the side chains within 6 Å of the mutation site. The protein backbone within 3 residues of the ...
The rheological parameters of drilling fluid with 5 wt% microcapsules increased slightly, and the filtration loss decreased, indicating good compatibility. In addition, it is convenient to adjust the melting temperature of the core materials by adding NaCl with different concentrations. This study is ...
