Electrospun fibrous sorbents for the removal of uranium and americium from aqueous media

Polymer International, EarlyView.
Polymethacrylate‐based electrospun microfibers with tertiary amino functionalities are evaluated as adsorbents for U‐232 and Am‐241 in both simplified and complex (seawater) water matrices, highlighting their ability for efficient actinide removal. Abstract Polymethacrylate‐based electrospun microfibers containing tertiary amino functionalities were ...

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 ...

Physicochemical Properties of Mesoporous Organo-Silica Xerogels Fabricated through Organo Catalyst

Membranes, 2021
The physicochemical properties of organo-silica xerogels derived from organo catalyst were pervasively investigated, including the effect of one-step catalyst (citric acid) and two-step catalyst (acid-base), and also to observe the effect of sol pH of ...

Mixed TiO2–SiO2 thin coatings for selective adsorption and sunlight‐powered photodegradation of cationic pollutants

Responsive Materials, EarlyView.
Environmental pollution and water scarcity demand innovative purification methods. This study presents a sol‐gel approach to fabricate mixed silica–titania thin films joining photocatalytic activity with selective sorption capability. The films exhibit higher surface area, enhanced degradation of cationic and improved performance over bare titania ...

Time‐resolved synchrotron X‐ray total scattering of alkali‐activated materials with high and low calcium contents

Journal of Synchrotron Radiation, EarlyView.
Synchrotron in situ high‐energy X‐ray total scattering/pair distribution function (PDF) analysis quantifies the time‐resolved structural evolution of high and low calcium alkali‐activated binders, with PDF peak evolution tracking reaction progress and correlating with calorimetry (R2 > 0.97).

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.

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

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

ENERGY &ENVIRONMENTAL MATERIALS, Volume 9, Issue 5, September 2026.
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 ...
