Study of the Efficiency of Doped Sol-gels Synthesized by Conventional Heating Versus Gamma Radiation Polymerization Techniques as adsorbents for Zn2+ and Pb2+ from Wastewater

Journal of Scientific Research in Science
New doped sol-gel adsorbents based on blank sol-gel glass (tetraethoxysilane (TEOS)), which are TEOS/polyaniline (PANI) and its 4-methyl and 4-methoxyaniline derivatives (PANIs) and TEOS/PANIs/Acrylamide (Am) were synthesized using conventional thermal ...

Corrosion Protection of Copper with Hybrid Sol-Gel Containing 1H-1, 2, 4-triazole-3-thiol [PDF]

Iranian Journal of Chemistry & Chemical Engineering, 2016
To improve the corrosion protection of copper metal, 0.01M concentration of 1H-1,2,4-triazole-3-thiol (TAT) was incorporated into the hybrid sol-gel monolayers containing 3-glycidoxypropyltrimethoxysilane (GPTMS) and Tetraethoxysilane (TEOS).

Rapid Photogelation of Low‐Concentration Polymer Solutions via Photodimerization of o‐Ethylnitrobenzene

Advanced Science, EarlyView.
Upon UV irradiation, flexible and tough hydrogels are formed rapidly (>0.5 s) from dilute (>0.5 wt%) solutions of o‐ethylnitrobenzene–modified PVA. At ∼1.5 wt%, the hydrogels withstand up to 10 MPa compression, remain handleable even after 200‐fold swelling.

Liquid Gallium Nanozyme Coatings Enable Sustained Nitric Oxide Generation With Antioxidant and Anti‐Inflammatory Functions

Advanced Science, EarlyView.
Liquid gallium (Ga) acts as a catalytic center for nitric oxide (NO) generation within a tannic acid–zirconium metal–phenolic network coating. Stabilized Ga nanoparticles catalyze S‐nitrosothiol decomposition through surface electron transfer, enabling controlled NO production, enhancing endothelial biocompatibility, and providing antioxidant and anti ...

Magnetoelectric BaTiO3/CoFe2O4 Thin‐Film Meshes for Neuronal Differentiation

Advanced Science, EarlyView.
We engineer an epitaxial BaTiO3/CoFe2O4 magnetoelectric mesh that overcomes boundary‐induced mechanical clamping. Progressively reducing the mechanical constraint, from substrate‐clamped to PDMS‐transferred and ultimately freestanding, enhances magnetic‐to‐electric transduction and strengthens magnetoelectric coupling.

Sol gel-derived rare earth-activated confined structures for photonics

, 2004
This paper deals with sol gel-based photonic structures, which allow to control and modify the optical and spectroscopic properties of rare earth ions. The most significant properties obtained for sol gel-derived planar waveguides and 1-D photonic band ...

Architecting Phase‐Selective Interlayers for Stable SiOx Lithium Storage via Dual‐Function Design

Advanced Science, EarlyView.
Silicon anodes offer high capacity but suffer severe volume expansion. Silicon monoxide (SiO) buffers expansion, yet uncontrolled lithiation irreversibly consumes lithium as Li2O and oxygen‐rich silicates. Here, we design a layered SiOx featuring a phase‐selective conductive interfacial interlayer (PSCII), i.e., a Li4SiO4‐rich, ion‐accessible ...

Lactobacillus‐Loaded Bioadhesive Hydrogel with Prolonged Retention and Microenvironmental Remodeling for Endometrial Repair and Fertility Restoration

Advanced Science, EarlyView.
A bioactive adhesive hydrogel capable of long‐term uterine retention (>14 days) and local microenvironment modulation is developed by straightforward integration of α‐lipoic acid, L‐arginine, tannic acid, and Lactobacillus johnsonii, which can markedly enhance endometrial repair and restore fertility in a rat model of endometrial injury.
