Metric Options: Counts1 Year3 YearSelecting the 1-year or 3-year option will change the metrics count to percentiles, illustrating how an article or review compares to other articles or reviews within the selected time period in the same journal. Selecting the 1-year option compares the metrics against other articles/reviews that were also published in the same calendar year. Selecting the 3-year option compares the metrics against other articles/reviews that were also published in the same calendar year plus the two years prior.
Example: if you select the 1-year option for an article published in 2019 and a metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019. If you select the 3-year option for the same article published in 2019 and the metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019, 2018 and 2017.

Article Description
The matrix material for hybrid membranes was prepared via curing of bisphenol A diglycidyl ether (DGEBA) with poly(ethylene glycol)diamine (DGEBA-c-PEGDA). The design of gold nanoparticles and poly(methyl methacrylate) coated gold nanoparticles (PMMA-AuNPs) as reinforcement was also considered. Morphology, size and distribution of PMMA-AuNPs were deliberated through transmission electron microscopy. The membranes of poly(vinylidene fluoride) (PVDF) and DGEBA loaded with PMMA-AuNPs were prepared by phase inversion method (DGEBA-c-PEGDA/PVDF/PMMA-AuNPs 0.1–1). Scanning electron microscopy was employed to study the fractured membrane surface and phase separated structure with nanopores were observed. The tensile strength was increased from 79.3 to 98.7 MPa when PMMA-AuNPs loading was increased from 0.1 to 1 wt.%. The glass transition temperature also improved with filler loading from 179 to 232°C. The membrane properties measured via membrane filtration set-up revealed increased pure water permeation flux, recovery and salt rejection for membrane with higher PMMA-AuNPs content. DGEBA-c-PEGDA/PVDF/PMMA-AuNPs membrane with 1 wt.% loading showed water flux of 50.2 mLcm min and salt rejection ratio of 88.8 %. Efficiency of the PMMA-AuNPs nanoparticles reinforced membranes for the removal of heavy metal ions was found to be 99 %.
