TL;DR: In this paper, a simple chemical treatment to the polymeric membrane composed of poly (isobutylene-alt-maleic anhydride) was performed, which has resulted in better performance in terms of rejection of CaCl2 and NaCl solutions.
Abstract: Present article describes about the preparation of Nanofiltration (NF) composite membranes by a simple chemical treatment to the polymeric membrane composed of Poly (isobutylene-alt-maleic anhydride). After composition, anhydride functionality was converted to diacid functionality by hydrolysis using sodium hydroxide solution. Further, membrane was characterized by ATR-IR, DSC and SEM. Charge confirmation was done by IEC. Water uptake and contact angle analysis was carried out to study the hydrophilicity of the membrane. The performance study was carried out by using NaCl and CaCl2 solutions. Membranes were having higher charge density, which has resulted in better performance in terms of rejection of CaCl2 and NaCl solutions. The main focus of this research is to evaluate the effect of alkali treatment on Donnan and size exclusion mechanism during membrane filtration.

TL;DR: In the title hydrate, C23H16N4O2·H2O, the pyrazole ring is approximately planar, with a maximum deviation of 0.023 (1) Å, and makes dihedral angles of 28.63”(6)° with the naphtho[2,1-b]furan ring system and the benzene ring, respectively.
Abstract: In the title hydrate, C23H16N4O2·H2O, the pyrazole ring is approximately planar, with a maximum deviation of 0.023 (1) A, and makes dihedral angles of 28.63 (6) and 46.44 (7)° with the naphtho[2,1-b]furan ring system and the benzene ring, respectively, In the crystal, O—H⋯N, O—H⋯O, N—H⋯O, N—H⋯N, C—H⋯O and C—H⋯N hydrogen bonds link the molecules, forming sheets lying parallel to the ab plane. The crystal structure also features C—H⋯π interactions involving the centroids of the pyrazole and benzene rings.

TL;DR: In this paper, the design, development, and application of new membrane materials, fabrication methods for controlling the filtration size regime, analytical tools for performance testing, and molecular modeling for transport and separation are reviewed.
Abstract: Water purification for human use, ecosystem management, agriculture, and industry is emerging as a leading global priority. Access to sufficient clean water ultimately requires improvements over the current state of water filtration technology. Membrane technologies for water purification have been actively pursued for decades, but with recent innovation of both analytical and fabrication tools, more advanced membrane technologies are surfacing. Here, we review the design, development, and application of new membrane materials, fabrication methods for controlling the filtration size regime, analytical tools for performance testing, and molecular modeling for transport and separation. Membrane chemical stability, fouling, and environmental impact as open questions are also presented.
