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.

Findings on Nanocrystals Detailed by Investigators at South Valley University (Fabrication of Polysulfone Membranes By Blending With Polyaniline and Cellulose Nanocrystals: Towards the Effective Separation of Oil-in-water Emulsions)
2023 JUL 03 (NewsRx) -- By a News Reporter-Staff News Editor at Nanotech Daily -- Current study results on Nanotechnology - Nanocrystals have been published.
Article Description
In the present work, we developed a hybrid membrane via phase inversion process composed from polysulfone (PSF), cellulose nanocrystals (CNCs), and polyaniline (PANI) polymers for oil/water separation. Multiple techniques were used to characterize the developed membranes. Results demonstrated that under a gravity-driven process, the blended PSF membrane with CNC and PANI had a greatly higher water flux of 31.10, 29.01 and 29.95 L m h for pure water, soybean water mixture, and diesel water mixture respectively as compared to pure PSF and PSF/CNC membranes. Meanwhile, the water flux values under constant pressure-driven process, high water flux of PSF/CNC/PANI membrane could reach 800 L m h KPa for various types of oils. The results showed ultrafiltration (UF) membrane with good micro-porosity, acceptable hydrophilicity, and good mechanical properties. Moreover, PSF/CNC/PANI membrane possessed high permeability properties at gravity-driven and pressure-driven processes for various oil water mixture separation with oil rejection efficiency (~ 88.2%).
