“…Most research aimed at increasing boron rejection of membranes has investigated the effects of desalination process operating conditions such as pH, temperature, salinity and pressure [23,24]. For example, a recent study by Nir et al demonstrated the effectiveness of pH adjustment to enable efficient boron removal in a single-stage pass using ultra-low energy, high-flux RO membranes [25][26][27]. Other efforts include: (1) process flow optimization approaches [13,28];…”

Removal of boron from saline water sources has presented a major challenge for commercially available reverse osmosis desalination membranes. In this work, we report the boron and sodium chloride separation properties of truly defect-free, highly selective, interfacially polymerized aromatic polyamide thin-film composite membranes. The fabricated membranes show potential for separating sodium chloride with a maximum rejection of 99.6% obtained for the optimized film-forming protocol under lab-scale brackish water desalination conditions. This translated into promising boron rejection performance with rejections of up to 99% at pH 10, higher than a number of commercially available reverse osmosis membranes tested in-house. Comprehensive characterization including X-ray photoelectron spectroscopy, atomic force microscopy, scanning electron microscopy, ellipsometry, and surface charge measurements revealed intimate insights on interfacially polymerized polyamide membrane structure-property relationships. Increased membrane crosslinking was shown to be the primary determining factor for membrane permselectivity performance. Furthermore, relationships were established between microstructural properties such as crosslinking and morphological characteristics like surface roughness, highlighting an intricate and complex structure formation mechanism.

Boron and lithium behaviour in river waters under semiarid climatic conditions

“…The Standard-Model (SM) is known as the most complete and rich model that is capable of explaining a large number of experimental data. Despite this, SM is incomplete as it is unable to explain some phenomena such as CP -violation [1,2], neutrino mass [3,4], existence of dark matter and dark energy [5] etc. This indicates that there should be extensions to the SM to answer these open questions that cannot be addressed by SM.…”

In this study, we explore the eects of CP -violating anomalous interactions of the top-quark through the semileptonic decay modes of the top-quark arising due to pairproduction of t t at the Large Hardon Collider. Predictions on the LHC sensitivities of the coupling strength to such CP -violating interactions would be discussed for the 13 TeV LHC data and for the future hadron collider with 14 TeV energy.
