Distinct microbial community along the chronic oil pollution continuum of the Persian Gulf converge with oil spill accidents [PDF]
Scientific Reports, 2021 The Persian Gulf, hosting ca. 48% of the world’s oil reserves, has been chronically exposed to natural oil seepage. Oil spill studies show a shift in microbial community composition in response to oil pollution; however, the influence of chronic oil ...

Evaluation of Mitigation Role of L-Phenylalanine-Based Low-Molecular-Weight Gelator against Oil Pollution-Induced Nile Tilapia Toxicity [PDF]
Gels, 2023 A lot of oil is leaked into aquatic environments, significantly impacting fish health and, consequently, human populations. This study aimed to introduce an L-phenylalanine-based low-molecular-weight gelator (expressed as Z-Phe-C18) as a smart ...

Facile Preparation of Dense Polysulfone UF Membranes with Enhanced Salt Rejection by Post-Heating
Membranes, 2023 Polysulfone (PSf) membranes typically have a negligible rejection of salts due to the intrinsic larger pore size and wide pore size distribution. In this work, a facile and scalable heat treatment was proposed to increase the salt rejection.
