Discriminating Bacteria With Functionalised Nanoporous Xerogels

open access: yesProcedia Chemistry, 2012
AbstractA new colorimetric and easy-to-use solid sensor for the detection of indole-producing bacteria is described. The sensor is a nanoporous matrix with tailored pores doped with a reactant, DMACA. The sensor turns rapidly from transparent to green-blue when exposed to metabolic indole coming from bacteria cultures, both in liquid and gas phases. An

Ultrasonic preparation of mesoporous silica using pyridinium ionic liquid [PDF]

open access: yes, 2016
Mesoporous silica matrices have been prepared via classic acid catalyzed and sono-catalyzed sol-gel routes. Tetramethoxysilan (TMOS) and methyl-trimethoxysilane (MTMS) were used as silica precursors, and N-butyl-3-methylpyridinium tetrafluoroborate ...

Rheological behaviour and spectroscopic investigations of cerium-modified AlO(OH)colloidal suspensions [PDF]

open access: yes, 2011
The rheological behaviour of aqueous suspensions of boehmite (AlO(OH)) modified with different Ce-salts (Ce(NO3)3, CeCl3, Ce(CH3COO)3 and Ce2(SO4)3) was investigated at a fixed Ce/Al molar ratio (0.05).

Synergistic Photophysical and Mechanical Enhancement in Europium Supramolecular Hydrogel by Incorporating Gd(DPA)3 Complex (DPA = Dipicolinate)

open access: yesChemistryOpen, Volume 15, Issue 5, May 2026.
Lanthanide‐based hydrogels incorporating Ln(DPA)3 complexes are synthesized and exhibit enhanced mechanical and luminescent properties. Increased complex concentration improves stiffness and emission intensity without altering coordination symmetry. Computational insights reveal preserved structural features, while lifetime changes highlight hydrogel ...

Sintering of Negative and Zero Thermal Expansion Phases in A2M3O12 Family: A Review

open access: yesphysica status solidi (b), Volume 263, Issue 5, May 2026.
This study assesses multiple synthesis methods for A2M3O12 powders, as well as consolidation and sintering routes for preparation of monolithic A2M3O12 ceramics. Correlations between powder features, consolidation, and sintering have been discussed to enable the fabrication of high‐density A2M3O12 monoliths with fine microstructure and improved ...

Fluorescent Supramolecular Gels Based on D‐Sorbitol Derivatives

open access: yesSmall, Volume 22, Issue 27, 14 May 2026.
Sugar‐based fluorescent low‐molecular‐weight gelators (LMWGs) DNapS, DBTDS, and MCumS, prepared by a green, scalable route, form supramolecular gels in water, organic, and deep eutectic solvents. MCumS yields solvent‐dependent nanofibrous networks and viscoelastic injectable eutectogels.

Smart NIR‐Emitting Organometallo Pt(II)‐Ionosilica Aerogel for Selective Au(III) Sensing and Recovery

open access: yesSmall, Volume 22, Issue 27, 14 May 2026.
This study reports a near‐infrared emitting ionic aerogel composed of cationic cyclometalated Pt(II) moieties linked by Si─O─Si bonds. The resulting porous hybrid material enables the selective detection and recovery of Au(III) ions from mixed‐metal solutions. Owing to its reversible luminescent response and thiourea‐assisted gold recovery, the aerogel
