In situ salt precipitation at the Dead Sea [PDF]

Limnology and Oceanography, 1983
Halite crystals were observed, for the first time, on the surface of the central part of the Dead Sea on 6 February 1979. This precipitation is assumed to be the result of an increase in the salt concentration at the lake surface by evaporation and raises some questions on the degree of saturation of the Dead Sea with respect to halite, the mechanism ...

Mechanisms of Degradation in Li‐Ion Batteries Under Low Temperature Exposures

Advanced Functional Materials, EarlyView.
Low‐temperature exposures, or freeze‐thaw cycles, are observed to significantly accelerate the degradation of Li‐ion batteries. A combination of electrolyte phase separation and mechanochemical stress leads to reversible and irreversible performance losses.

Capillary‐Driven Backflow During Salt Precipitation in a Rough Fracture

Water Resources Research
Salt precipitation is a crucial process occurring during CO2 injection into saline aquifers. It significantly alters the porous space, leading to reduced permeability and impaired injectivity.

Examining the impacts of salt precipitation on soil hydraulic properties at the field lysimeter scale

Applied Computing and Geosciences
Previous bench-scale investigations have demonstrated that salt precipitation reduces soil saturated hydraulic conductivity (Ks) due to the clogging effect. However, this conclusion may be confounded by the boundary effects inherent to the physical model.

Multifunctional Solid Polymer Electrolyte Films Integrating Intrinsic Self‐Healing and Dual Photo‐/pH‐Responsive Ionic Sensing for Intelligent Flexible Electronics

Advanced Functional Materials, EarlyView.
Multifunctional solid polymer electrolyte (SPE) films integrating intrinsic self‐healing, mechanical stretchability, and dual photo‐ and pH‐responsive ionic conductivity are developed. Constructed from thermoplastic polyurethane (TPU) and hydrogen‐bonded poly(thiourea triethylene glycol) (PTUEG3), these films form a dynamic supramolecular network ...

Unraveling salt precipitation mechanisms in geological CO2 storage: insights into dominant driving forces

InterPore Journal
Salt precipitation during geological CO2 storage (GCS) in saline aquifers can impair injectivity of large-scale projects. Laboratory studies indicate that this process is sensitive to capillary force, but scaling-up to field conditions is complex due to

Interaction‐Driven Assembly Pathways in Heterogeneous Active Microrobotic Systems

Advanced Functional Materials, EarlyView.
Peanut‐ and cube‐shaped light‐powered microrobots exhibit distinct magnetic and photocatalytic responses that determine their heterogeneous self‐assembly. In the dark, magnetic dipole interactions drive colloidal copolymerization with cubes acting as nucleation centers, whereas under light irradiation, phoretic interactions compete with magnetic ...

Sulfur‐Free Ultrahigh‐Refractive‐Index Polymers Enabled by Densely Packed Oxygen‐Bridged Dibenzofuran‐Cardo Architectures

Advanced Functional Materials, EarlyView.
A new class of sulfur‐free, oxygen‐bridged dibenzofuran‐based polymers is developed for ultrahigh‐refractive‐index applications. The rigid π‐extended architecture and enhanced molecular polarizability enable exceptional optical performance, combining refractive indices up to 1.848 with high Abbe numbers and full visible transparency. This work offers a

Mineral Deposition From Liquid Precursors Triggered by Complementary Polyelectrolytes

Advanced Functional Materials, EarlyView.
Polyelectrolyte additives can delay or prevent crystal nucleation in supersaturated solutions of insoluble mineral salts such as calcium carbonate. This work reports that adding a second, oppositely‐charged polyelectrolyte leads to immediate mineral crystallization from such metastable solutions.
