Bio‐Inspired Robust Non‐combustible Bioplastic with Superinsulated Energy Harvesting for Intelligent Firefighting

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
This study develops a novel non‐combustible chitosan‐based bioplastic (NCCB) via ethanol‐induced surface assembly. The material's inherent flame retardancy and thermally insulating, rough surface enable high‐performance TENGs. The NCCB‐TENG maintains stable output even when exposed to fire and exhibits dual sensitivity to temperature (25–200°C) and ...

Fluorescent Supramolecular Gels Based on D‐Sorbitol Derivatives

open access: yesSmall, 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.

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

open access: yesSmall, EarlyView.
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

Engineered surface strategies to manage dental implant‐related infections

open access: yesPeriodontology 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.

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
