This paper presents an Unknown Input Observer (UIO) for a class of Lipschitz nonlinear systems affected by disturbances/faults and having slow internal dynamics after the decoupling (UI). Thanks to Asymptotic Decoupling notion, constraint related is bypassed. The UIO time varying that allows obtain notion. It will be shown proposed approach enhance convergence rate UIO. enhancement state estima...

The covalent linkage of graphene acid (GA) with amine-functionalized UiO-66-NH 2 via an amide bond. resultant hybrid GA@UiO-66-NH acts as a chemiresistive CO sensor wth significant efficiency owing to its unique structural features.

This work reports for the first time functionalization of 2-aminoterephtalate linker UiO-66-NH2 with cyclopentyl or cyclohexyl rings. The resulting materials displayed reduced bandgaps enhanced separation photogenerated charges due to inductive electron effect cycloalkyl substituent. These functionalized higher photocatalytic performance towards solar abatement acetaminophen than UiO-66-NH2. ac...

Cr(VI) is one of the most toxic heavy metals, posing multiple threats to humans and ecosystems. Photoreduction para-toxic Cr(III) effective ways remove metal chromium but still challenging. Herein, Ti3C2/UiO-66-NH2 composites with different ratio Ti3C2 were synthesized via an in situ solvothermal process used for enhanced photocatalytic removal first time. The UiO-66-NH2 nanoparticles dispersed...

Li-O2 batteries have attracted extensive attention because of their theoretical specific energy equivalent to gasoline, but the poor electrical conductivity Li2O2 leads high overpotential, which limits further development and application. Herein, this work introduces Ce-UiO-66, a metal-organic framework material, as photocatalyst reduce overpotential in discharging charging processes. With simp...

Metal-organic frameworks with Zr6 nodes, UiO-66 and NU-1000, were investigated as supports for Ir(CO)2 and Ir(C2H4)2 complexes. A single bonding site for the iridium is identified on the nodes of NU-1000, whereas two sites are identified on UiO-66, although at low iridium loadings only one site is occupied. Density functional theory calculations provide structural results that are in good agree...
