In this study, an efficient photocatalyst for water splitting was developed. The Cr2O3 and TiO2 nanoparticles (Cr2O3-TNPs) nanocomposite with (Chitosan extract) created using ecologically friendly methods, such as the impregnation technique exhibits nano spherical (TNPs) shape structure. According to researchers, material enhanced its ability absorb ultraviolet light while also speeding up reco...

Al2O3-Cr2O3 refractories are completely substitution solid solutions and can effectively resist slag erosion when used as an industrial furnace lining. In order to provide suitable chromium corundum refractory with excellent resistance mechanical properties for smelting reduction ironmaking, samples different mass percentages (0, 10, 20, 30, 40 wt.%) of Cr2O3 were prepared by a normal pressure ...

به منظور افزایش بازدهی و عمر کاری صفحات اتصال دهنده فلزی مورد استفاده در سلولهای سوختی اکسید جامد از پوششهای محافظ و رسانا استفاده می شود. در این پژوهش فولاد فریتی زنگ نزن 430 aisi در یک مخلوط پودری پایه کبالت به روش سمانتاسیون فشرده پوشش داده شد و تأثیر ضخامت لایه اکسیدی کرومیا (cr2o3) بر روی مقاومت سطحی ویژه (asr) توسط آنیل همدما در 800ºc و آنیل ناهمدما در دماهای بین ºc 400-900 بررسی شد. نتای...

Silicon is an appealing lithium-ion battery anode material; unfortunately, it confronted with unsatisfactory cyclability owing to its large volume change. Herein, we design a unique ternary composite material (Si/Cr2O3/C), where the Si nanoparticles are confined in carbon-coated chromium oxide multi-shell hollow spheres (MSHSs). Encapsulating MSHSs effectively boosts available free space for ch...

Hybrid nanocomposites based on ferrimagnetic (FiM) Fe3O4 and magnetoelectric antiferromagnetic (AFM) Cr2O3 nanocrystals were synthesized to offer a particular three-dimensional (3D) interface between the two oxides. This interface favours an intermixing process (demonstrated by combining Raman spectroscopy and magnetization measurements) that determines the final magnetic behavior.
