Fabrication of Cr2O3 Nanoparticles Using Okra Plant Extract for Antimicrobial Activity

Journal of Kufa-Physics, 2022
Cr2O3 NPs were synthesized using Okra extract with two methods; the simple chemical method and sol-gel method. XRD analysis showed that the crystal size of Cr2O3 in a simple chemical method was (16.15) nm and with sol-gel method were 16.6 nm, 16.14 nm ...

Nonoxide Sol-Gel Synthesis of Terbium-Doped Silicon Nitride Phosphors

, 2009
Exposure of solutions of Tb(N(SiMe3)2)3 with SiCl(NEt2)3 in tetrahydrofuran to dry ammonia results in polymeric xerogels. Heating these gels in ammonia leads to amorphous Tb:SiNx phosphors that exhibit bright green luminescence under UV irradiation.

Electrospun Wood‐Derived Biopolymers as Electrodes in Electrochemical Energy Storage Technologies

Advanced Functional Materials, EarlyView.
Electrospinning transforms wood‐derived cellulose and lignin into architecturally defined, binder‐free carbon electrodes with tuneable porosity and functionality. This review shows how fibre design enables decoupled charge and mass transport, enhancing performance across battery systems, while identifying key challenges in spinnability, scalability ...

Roll‐to‐Roll Processable EC/TC Hybrid Smart Windows Driven by a Bidirectional Dual‐Chromic Polymer Electrolyte

Advanced Functional Materials, EarlyView.
We present a scalable EC/TC hybrid smart window using a DCPE that enables tunable solar modulation (ΔTsol:15–43%), fast electrochromic switching (<90 s), and strong thermal blocking (10–14°C reduction). HPMC improves thermal stability, while an optimized ISL enhances EC performance.

Mechanical Programming of PEGDA‐β‐CD Polyrotaxane‐Based Hydrogels via Host–Guest Molecular Recognition

Advanced Functional Materials, EarlyView.
A mechanically programmable hydrogel for tissue engineering is developed by modulating the molecular threading density of poly(ethylene glycol) diacrylate‐β‐cyclodextrin (PEGDA‐β‐CD) polyrotaxane and combining it with β‐CD‐modified gelatin. The polyrotaxane‐guided transition from disordered pores to laminar microstructures enables precise tuning ...

Mesoporous silica matrices derived from sol-gel process assisted by low power ultrasonic activation [PDF]

, 2009
The present work contributes to elucidating the differences between silica gels obtained by low doses ultrason- ic activation, and those obtained by the conventional method, termed as classical sol gel.
