The paper explores the application of the Modal Truncation algorithm in Model Order Reduction, focusing on its effectiveness in reducing high-dimensional mathematical model. The algorithm identifies dominant modes governing dynamic responses, discards the high-order model, and reconstructs a new model with reduced dimensions.

Multimetallic nanocatalysts have remarkably revealed activities in various catalytic applications. Herein, the ternary nanocatalysts based on palladiumvanadium-cobalt were successfully synthesized through the reduction of their salts with sodium borohydride including impregnating of activated carbon (AC) substrate with colloid solution of metallic nanoparticles (PdVCo/C).

Uniform and magnetic recyclable hollowsphere Zn doped Fe3O4 were successfully synthesized via simple one-pot solvothermal route. Morphology and structure of as-obtained products was characterized by XRD, SEM, HRTEM methods. The Zn-doped Fe3O4 hollowsphere exhibited high photocatalytic activity for degradation of hexavalent chromium under visible light irradiation.

In this research, Ag-Ag3PO4/Cellulose aerogel composite was synthesized using hydrothermal reduction and freeze-drying methods. By combining the photocatalytic activity of the semiconductor AgAg3PO4 and cellulose aerogel synthesized from agricultural waste sources, the synthesized Ag-Ag3PO4/Cellulose aerogel composite has overcome the disadvantages of pure Ag3PO4 and significantly improved the photocatalytic activity.
