The synthesis of ternary nanocomposites with tailored properties based on polymer blends is gaining popularity all over the world. Our work introduces a novel ternary nanocomposite of poly (ethylmethacrylate)/polystyrene/silver nanoparticles (PEMA/PS/Ag NPs). Silver nanoparticles were synthesized via laser ablation route at different laser times (5, 10, 15, 20, and 30 min) and scattered in PEMA/PS...... hiện toàn bộ

Novel nickel and copper phthalocyanine polymers, with uniformly carboxylic end groups and carbonyl groups as bridges linking the phthalocyanine units, were successfully prepared. Structural modelling and atomic absorption spectroscopy confirmed the network polymeric structure and suggested at least nine phthalocyanine units in each polymeric network. The dielectric properties of the prepared polym...... hiện toàn bộ

The changes of properties of wood-based Cu–Ni composites were studied via a simple electroless Cu and Ni method on wood surface to obtain Cu–Ni multilayer composites with excellent properties. The results showed that the wood was conducted via two times electroless Cu and one times electroless Ni had better performance, obtaining good surface roughness (9.99 μm) and good hydrophobic performance (c...... hiện toàn bộ
Synthesis and Characterization of Ta-Doped WO3 Nanomaterials for Their Application as an Efficient PhotocatalystSpringer Science and Business Media LLC - Tập 33 - Trang 3454-3467 - 2023

For the degradation of MB dye, pure and Ta-doped (1 to 5%) WO3 nanoparticles (NPs) have been synthesized in the current work. Facile and efficient hydrothermal method has been carried out to synthesize pure and Ta-doped WO3 NPs. By using SEM, XRD, UV–Vis, PL, FTIR and Raman spectroscopy analysis, the morphological, structural, optical, and spectral features have been addressed. Due to the well-mat...... hiện toàn bộ
Adsorption Selectivity of CO2 and CH4 on Novel PANI/Alkali-Exchanged FAU Zeolite NanocompositesSpringer Science and Business Media LLC - Tập 27 - Trang 1281-1291 - 2017
Samira Salehi, Mansoor Anbia
Adsorption capacity and selectivity of carbon dioxide (CO2) and methane (CH4) in faujasite (FAU)-type zeolites NaX and NaY have been studied by employing a volumetric measurements at 298, 323, and 348 K and a pressure range up to 5 bar. Ion exchange was performed on FAU zeolites with alkali metal cations Li+ and K+. The alkali-exchanged zeolitic adsorbents were characterized by scanning electron m...... hiện toàn bộ
Bifunctional Luminescent Rare Earth Metal–Organic Frameworks for Highly Sensing Fe3+ Ions and TNPSpringer Science and Business Media LLC - - Trang 1-12 - 2024

Two isostructural rare earth metal–organic frameworks, namely [Re2(BBTC)(DMF)5Cl2]·2DMF·H2O [BBTC4– = 1,1'-butadiynebenzene-3,3',5,5'-tetracarboxylate, Re = Y (1) and Ho (2)], have been prepared via solvothermal reaction. Single crystal X − ray analyses reveal that complexes 1 and 2 both crystallize in the P21/m space group. Topological analyses suggest that these frameworks possess the same two–d...... hiện toàn bộ
