Abstract: This gas separation device separates a gas to be separated from a mixed gas. The gas separation device has a supply flow path, a recovery flow path, and a semipermeable membrane. The mixed gas is supplied to the supply flow path. The gas to be separated is recovered from the recovery flow path. The semipermeable membrane separates the supply flow path and the recovery flow path. The semipermeable membrane selectively permeates the gas to be separated.[...]
Our summary: This device separates a specific gas from a mixed gas using a semipermeable membrane. The mixed gas enters through a supply flow path. The desired gas is collected from the recovery flow path.

Carbon dioxide emissions elimination for reverse osmosis desalination units of remote islands via photovoltaic and battery solution. The case of Karpathos Island
Published on 2026-06-06 by @OXFORD
Abstract: AbstractRecently, the imperative water demand problem of small islands in the South-East Mediterranean area is being faced with the development and operation of new reverse osmosis (RO) desalination plants at high operational and environmental cost. One of the most serious RO desalination unit’s problems is their high-energy demand. This water demand coincides with the electricity demand, both peaked during the summer imposing the existing local electrical power stations to operate near their [...]

A Generalized Fick’s Flux with Caputo Derivative
Published on 2026-02-03 by N. A. Shah, Khalid Masood, Dumitru Vieru @MDPI
Abstract: The present study investigates the generalized dispersion of a solute in an incompressible MHD flow via a rectangular channel with injectable or suctioned walls. The mathematical model of dispersion suggests a distinct type of mass flux expressed as a fractional partial differential equation based on the time-fractional Caputo derivative. The mass flow in the model under investigation is determined by both the concentration gradient and its historical evolution. A constant external magnetic fiel[...]
Our summary: This study presents a mathematical model for solute dispersion in incompressible MHD flow using a fractional partial differential equation. The model incorporates the time-fractional Caputo derivative and analyzes the effects of various parameters on mass flux. Analytical solutions for solute concentration are derived and examined through numerical simulations.
