Optimization of Low Salinity Water/Surfactant Flooding Design for Oil-Wet Carbonate Reservoirs by Introducing a Negative Salinity Gradient

Energies, 2022
Engineered water surfactant flooding (EWSF) is a novel EOR technique to reduce residual oil saturation; however, it becomes quite challenging to obtain Winsor Type III microemulsion and the lowest IFT under actual reservoir conditions if only low ...

Action of cabbeling-anticabbeling effect in formation of the halocline in estuaries on example of the Razdolnaya River (Peter the Great Bay, Japan Sea)

Известия ТИНРО, 2023
Nonlinearity effect of the seawater density equation for mixing of waters with different salinity is considered for a case of the halocline formation in estuaries. Depending on salinity, density of the mixture can be higher (at low salinity) or lower (at

Nanopore-Based Power Generation from Salinity Gradient: Why It Is Not Viable.

ACS Nano, 2021
In recent years, the development of nanopore-based membranes has revitalized the prospect of harvesting salinity gradient (blue) energy. In this study, we systematically analyze the energetic performance of nanopore-based power generation (NPG) at ...

Pressure Retarded Osmosis Power Units Modelling for Power Flow Analysis of Electric Distribution Networks

Energies, 2021
Pressure retarded osmosis (PRO) power units, which produce electrical energy from salinity gradient sources located at coastlines, are a technology still in the process of maturation; however, there is an expectation that this technology will need to be ...

Increases in the abundance of microbial genes encoding halotolerance and photosynthesis along a sediment salinity gradient [PDF]

Biogeosciences, 2012
Biogeochemical cycles are driven by the metabolic activity of microbial communities, yet the environmental parameters that underpin shifts in the functional potential coded within microbial community genomes are still poorly understood.

Novel Thermal Desalination Brine Reject-Sewage Effluent Salinity Gradient for Power Generation and Dilution of Brine Reject

Energies, 2020
Salinity gradient resource presents an essential role for power generated in the process of pressure-retarded osmosis (PRO). Researchers proposed several designs for coupling the PRO process with the desalination plants, particularly reverse osmosis ...

Taxonomic Composition and Salinity Tolerance of Macrozoobenthos in Small Rivers of the Southern Arid Zone of the East European Plain

Biology, 2023
This study investigated the species composition, distribution, and salinity tolerance of macrozoobenthos in 17 small rivers in the southern arid region of the East European Plain, which are characterized by a small channel gradient, slow-flowing or ...

River Plume Rooted on the Sea-Floor: Seasonal and Spring-Neap Variability of the Pearl River Plume Front

Frontiers in Marine Science, 2022
The buoyant river plume front exhibits substantial variability in the sea surface under energetic external forcing. Although highly dynamic, the river plume is often “rooted” at specific locations through the bottom river plume front.

Salinity Gradient Energy: Current State and New Trends

Engineering, 2015
In this article we give an overview of the state of the art of salinity gradient technologies. We first introduce the concept of salinity gradient energy, before describing the current state of development of the most advanced of these technologies.

Adaptive divergence and underlying mechanisms in response to salinity gradients between two Crassostrea oysters revealed by phenotypic and transcriptomic analyses

Evolutionary Applications, 2023
Comparing the responses of closely related species to environmental changes is an efficient method to explore adaptive divergence, for a better understanding of the adaptive evolution of marine species under rapidly changing climates.
