Chemo-Mechanical Interactions in the Ettringite Induced Expansion of Sulfate-Bearing Soils
Geosciences, 2019 Expansive sulfate-bearing soils are frequently encountered in transportation and construction practices. These soils are often treated with a lime or cement stabilizer to improve the relevant qualities.

What is osmosis? Explanation and understanding of a physical phenomenon [PDF]
arXiv, 2003 Although osmosis is a familiar phenomenon, and of pivotal importance in natural systems, it is seldom explained how it might work on the molecular level (if treated at all in physics text books). The standard treatment of osmosis in thermodynamics employs the concept of the chemical potential and does not give any clues how the process "really" works ...

Induced-charge electro-osmosis around metal and Janus spheres in water: Patterns of flow and breaking symmetries [PDF]
, 2014 We establish experimentally the flow patterns of induced-charge electro-osmosis (ICEO) around immobilized metallic spheres in aqueous electrolyte. The AC field modifies local electrolyte concentration and causes quadrupolar flows with inward velocities being smaller than the outward ones.

Advanced Healthcare Materials, EarlyView.Small extracellular vesicles (sEVs) are encapsulated into protective shells composed of metal‐phenolic networks (MPNs) and secondary poly(ethylene glycol) layers. This surface modification approach enhances the storage stability of sEVs while maintaining their integrity and functionality. The shells can be selectively disassembled under mild conditions.

Direct-drive ocean wave-powered batch reverse osmosis [PDF]
arXiv, 2021 Ocean waves provide a consistent, reliable source of clean energy making them a viable energy source for desalination. Ocean wave energy is useful to coastal communities, especially island nations. However, large capital costs render current wave-powered desalination technologies economically infeasible.

Critical flux-based membrane fouling control of forward osmosis: Behavior, sustainability, and reversibility [PDF]
, 2018 Membrane fouling is closely related to the concept of critical flux. Therefore, a fouling control strategy for forward osmosis (FO) membranes that is based on the critical flux is necessary.

Alternating Direction Implicit (ADI) schemes for a PDE-based image osmosis model [PDF]
, 2017 We consider \emph{Alternating Direction Implicit} (ADI) splitting schemes to compute efficiently the numerical solution of the PDE osmosis model considered by Weickert et al. for several imaging applications. The discretised scheme is shown to preserve analogous properties to the continuous model. The dimensional splitting strategy traduces numerically

Computational Modeling of Reticular Materials: The Past, the Present, and the Future
Advanced Materials, EarlyView.Reticular materials are advanced materials with applications in emerging technologies. A thorough understanding of material properties at operating conditions is critical to accelerate the deployment at an industrial scale. Herein, the status of computational modeling of reticular materials is reviewed, supplemented with topical examples highlighting ...
