Fluorescent Supramolecular Gels Based on D‐Sorbitol Derivatives

Small, EarlyView.
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.

ELABORATION OF ORGANIC-INORGANIC HYBRID MATERIALS OBTAINED BY CHEMICAL REACTION OF POLYMETHYLHYDROSILOXANE AND BI-FUNCTIONAL HETEROCYCLIC MOLECULES

Scientific Study & Research: Chemistry & Chemical Engineering, Biotechnology, Food Industry, 2014
New organic-inorganic hybrid materials G1-G5 were obtained by chemical reaction of polymethylhydrosiloxane (PMHS) and bi-functional heterocyclic molecules under 2:1 stoechiometry, in tetrahydrofurane as solvant, using hexachloroplatinic acid (H2PtCl2 ...

Engineered surface strategies to manage dental implant‐related infections

Periodontology 2000, EarlyView.
Abstract When exposed to the oral environment, dental implants, like natural surfaces, become substrates for microbial adhesion and accumulation, often leading to implant‐related infections—one of the main causes of implant failure. These failures impose significant costs on patients, clinicians, and healthcare systems.

Alumina–Zirconia Composite Filaments for 3D‐Printed Scaffolds With Bioglass Infiltration for Medical Applications

International Journal of Applied Ceramic Technology, Volume 23, Issue 2, April 2026.
This study demonstrates the innovative development of alumina–zirconia composite scaffolds produced by fused filament fabrication (FFF) and infiltrated with bioglass via the sol–gel method. The combination yielded highly porous three‐dimensional architectures (500 µm–1 mm), suitable for nutrient diffusion, vascularization, and cell colonization.

Discriminating Bacteria With Functionalised Nanoporous Xerogels

Procedia 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

Kern‑Schale: Versiegelung nanoporöser Partikel mit semipermeablen Kohlenstoffschichten befreit Hartkohlenstoffanoden von ihrem Dilemma

Angewandte Chemie, Volume 138, Issue 10, 2 March 2026.
Eine Kern‐Schale‐Strategie wird vorgestellt, um die hohen Verluste nichtgraphitischer Hartkohlenstoffanoden zu überwinden. Aktivkohle wird durch Gasphasenabscheidung mit einer semipermeable Kohlenstoffschicht versiegelt, wodurch die SEI‐Bildung und Natriumspeicherung räumlich getrennt werden.

Core‐Shell: Resolving the Dilemma of Hard Carbon Anodes by Sealing Nanoporous Particles With Semi‐Permeable Coatings

Angewandte Chemie International Edition, Volume 65, Issue 10, 2 March 2026.
A core–shell strategy is presented to overcome the high first‐cycle losses of non‐graphitic hard carbon anodes. Activated carbon is sealed by gas‐phase carbon deposition to create semi‐permeable shells that spatially separate SEI formation from Na storage in a retained nanoporous core. The resulting anode delivers 400 ± 24 mAh g−1 with an ICE of 82 ± 2%

Holographic Photopolymerizable Glass: Enhancing Exposure Sensitivity by Tailoring Photoinitiating Systems Based on BODIPY Dyes

Advanced Photonics Research, Volume 7, Issue 3, March 2026.
The holographic recording performance of the photopolymerizable hybrid sol–gel is enhanced by optimizing photoinitiating systems based on boron dipyrromethene dyes. Two‐ and three‐component type‐II photoinitiating systems are employed, and their photopolymerization efficiency is evaluated through holographic patterning at 532 nm.
