Ion-triggered reconfigurable hydrogels with salt-enhanced mechanical and swelling properties via network topological adaptation [PDF]

Nature Communications
Hydrogels typically deteriorate under high-salinity conditions because electrostatic screening and reduced polymer-solvent affinity suppress swelling and weaken load-bearing network connectivity. Here, we report a double-network hydrogel that strengthens

Ion pair and larger ion cluster formation in water interfacial regions: An atomic force microscopy study

AIP Advances, 2023
Interfacial regions attached to hydrophobic and hydrophilic surfaces have very low relative permittivities (ε ∼ 3–5), and these low values induce the formation of ion pairs.

Ion association in water solution of soil and vadose zone of chestnut saline solonetz as a driver of terrestrial carbon sink [PDF]

Solid Earth, 2016
The assessment of soil and vadose zone as the drains for carbon sink and proper modeling of the effects and extremes of biogeochemical cycles in the terrestrial biosphere are the key components to understanding the carbon cycle, global climate system ...

Cadmium status in chernozem of the Krasnodar Krai (Russia) after the application of phosphogypsum; pp. 501–515 [PDF]

Proceedings of the Estonian Academy of Sciences, 2017
The thermodynamic state of Cd in Haplic Chernozem with phosphogypsum for soil reclamation in doses of 10, 20, and 40 t ha–1 was evaluated. The role of chemical equilibrium in soil solutions as a cause of Cd status in soil was shown.

Induction of chirality in the charge transfer complex photochemistry

Journal of Photochemistry and Photobiology, 2023
Electron donor and acceptor undergo association in solution to form a weak molecular complex, namely a charge transfer complex. The formation of the complex is apparent by its new low-energy absorption band.
