Mechanistic Insights and Performance Advancements in Flow Capacitive Deionisation for Sustainable Energy Conversion

open access: yesElectrochemical Science Advances, Volume 6, Issue 4, August 2026.
ABSTRACT Flow capacitive deionisation is an advanced electrochemical technology for water purification and energy‐related applications. It represents a viable alternative to conventional desalination methods due to its low operating voltage, continuous electrode regeneration, and stable performance under moderate‐to‐high salinity conditions. The use of

Progressively Fenitised Schist and Carbonatitic Clasts From a Metasomatic Aureole Beneath the Alkalic Dunedin Volcano, Otago, New Zealand

open access: yesNew Zealand Journal of Geology and Geophysics, Volume 69, Issue 2, June 2026.
Clasts of albite‐porphyroblastic quartzofeldspathic schist, derived from the Otago Schist basement, occur within the Port Chalmers Breccia, a diatreme at the centre of the Dunedin stratovolcano, New Zealand. Schists have undergone varying degrees of replacement reactions (at temperatures of 300° to >500°C) producing hornfelses, with Ca‐ and K‐enriched ...

Millimeter/Nano‐Structured Metal Monolithic Catalysts: A Privileged Opportunity for Sustainable Water Purification

open access: yesRare Metals, Volume 45, Issue 6, June 2026.
ABSTRACT Cross‐scale assembly of metal (sub) nanoparticles and/or single atoms into millimeter/nanostructured metal monolithic catalysts (Min‐SMCs) is highly appealing for sustainable water cleanup, due to energy‐efficient catalyst recyclability, high infrastructure compatibility, and low metal‐releasing risks.

Study of optical constants and dielectric properties of nanocrystalline α-cordierite ceramic

open access: yesJournal of Asian Ceramic Societies, 2020
The nanocrystalline 2 Mg.2Al2O3.5SiO2 as amorphous-type α-cordierite was prepared by the modified sol-gel (or Pechini) technique. After calcination at 800ºC, the pressed powder as disk pellets was sintered at 1150ºC, 1250ºC, and 1350ºC.

The influence of activation and relaxation time on the synthesis of cordierite ceramics [PDF]

open access: yesJournal of the Serbian Chemical Society, 2006
Due to its properties, cordierite, 2MgO.2Al2O3 .5SiO2, is nowadays an attractive ceramic material for various applications. Mechanochemical activation of the initial components was used in order to decrease the sintering temperature.

Phase-transformation kinetics in triphasic cordierite gel

open access: yes, 2001
A triphasic cordierite-type gel was prepared from silica sol, boehmite sol, and an aqueous solution of Mg(NO3)(2). 6H(2)O. The silica sol was obtained from water glass by the ion exchange method, while boehmite sol was obtained by peptization of freshly ...

Densification and crystallization behaviour of colloidal cordierite-type gels [PDF]

open access: yesJournal of the Serbian Chemical Society, 2001
Three cordierite-type gels were prepared from an aqueous solution of Mg(NO3)2, a boehmite sol and silica sols of very small particle sizes. The effect of varying the silica particle size on the crystallization and densification behaviour was ...

Effect of Sintering Aid Composition and Porosity on the Oxyacetylene Torch Response of Silicon Nitride for RF Windows

open access: yesJournal of the American Ceramic Society, Volume 109, Issue 6, June 2026.
Silicon nitride samples were slip cast using yttrium oxide–aluminum oxide and ytterbium oxide sintering aids to fabricate plates with up to 40% porosity and compare them to a fully dense commercial standard. Silicon nitride plates were tested with an oxyacetylene torch to investigate changes in front and back face temperature, spectral emissivity ...
