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

open access: yes, 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.

Fabrication of Cr2O3 Nanoparticles Using Okra Plant Extract for Antimicrobial Activity

open access: yesJournal 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 ...

Microstructure, Thermal Transport, and Dry‐Sliding Tribology of Powder‐Metallurgy Al7075 Composites Reinforced With Sol–Gel‐Derived ZnO–rGO Hybrid Nanoparticles

open access: yesAdvanced Engineering Materials, EarlyView.
Sol–gel‐derived ZnO–rGO hybrid nanoparticles enable Al7075 powder‐metallurgy composites to achieve concurrent gains in hardness and thermal conductivity while markedly lowering friction and wear. The hybrid architecture couples ZnO‐based load support with rGO‐assisted lamellar sliding and heat spreading, revealing a promising route toward lightweight ...
