Effect of polymer architecture on the gas separation performance of PIM-1 membranes
Abstract: Molecular simulations are used to demonstrate the effects of chain architectureson the gas separation performance of PIM-1 membranes. Four different architectures(linear, H-shape, star, and dendritic) were considered to investigate the transport propertiesof four industrially relevant gases (CO2, CH4, O2, and N2). The results obtainedfor the linear PIM-1 agree well with the available experimental data. The simulationsindicate that it is indeed possible to tune the free volume morphology of PIM-1 membranesby …

One-Step Fabrication of Superomniphobic Pvdf-HFPSiO2Membrane for Long-Term CO2 Absorption inMembrane Gas Absorption System
Abstract: Membrane pore wetting is one of the major challenges for membrane gas absorption, especially when low surface tension liquid absorbents such as amine absorbents are utilized. To minimize diffusion resistance across the membrane, maintaining a non-wetted operating mode in membrane gas absorption is crucial. In this study, a superomniphobic polyvinylidene fluoride-cohexafluoropropylene membrane was fabricated by adding silica nanoparticles (SiO2) in an ethanol coagulation bath through non-solvent-induced phase separation. The surface …

Interpreting Place Memory as a Future Horizon for Architecture
Abstract: The creation of architecture, whether innovative or traditional, entails a certain attitude towards past architecture, an act of interpretation of the past, which requires a new outlook. Though architects should tread carefully and responsibly with regard to past architecture, the past should not cast its shadow on the architect’s imagination, but rather be the grain of inspiration for future change and development. One should not consider the past as separate …

A Review on Nano Filtration System
Abstract: In the later half of the 1980s, nanofiltration (NF) became a significant development in the purification of water. When NF was first introduced, it was marketed as a less energy-intensive substitute for traditional techniques like reverse osmosis (RO). However, as its special qualities and uses became clear, NF was acknowledged as a separate technology in 1988. Comprehending the differences between ultrafiltration (UF), RO, and NF is essential to appreciating its …
