Size Effects of TiO2 Nanoparticles as Supports for W‐ and NiW‐Catalysts for Selective 3‐Methylthiophene Desulfurization

open access: yesChemCatChem, EarlyView.
Rounded TiO2 nanoparticles we sucesfully synthesized with modulated sizes from 109 to 22 nm. We observed the WS2 and NiWS active phases forming parallel slabs to the surface. The presence of Ni helped W to be better dispersed, especially on the smallest nanoparticles, which resulted in the highest activity detected among the series.

Dual Lipase Immobilization on Kaolin‐Based Support for High Catalytic Efficiency and Long‐Term Stability

open access: yesChemCatChem, EarlyView.
This study presents the co‐immobilization of CALB and Eversa lipases on functionalized kaolin, followed by process optimization using the Taguchi method. The graphical abstract illustrates the immobilization strategy, optimization workflow, and computational analysis describing enzyme–support interactions, highlighting how structural and energetic ...

Synthesis, characterization, and performance of x_MoO3/Z‐22 and x_MoO3/MMP catalysts for biodiesel production

open access: yesThe Canadian Journal of Chemical Engineering, EarlyView.
Methyl transesterification of soybean oil using heterogeneous catalysts for biodiesel production. Abstract The growing global demand for renewable fuels has driven the search for efficient catalysts in biodiesel production. This study presents the synthesis and characterization of x_MoO3/Z‐22 and x_MoO3/MMP heterogeneous catalysts, and evaluates the ...

Isoperimetric inequalities on slabs with applications to cubes and Gaussian slabs

open access: yesCommunications on Pure and Applied Mathematics, EarlyView.
Abstract We study isoperimetric inequalities on “slabs”, namely weighted Riemannian manifolds obtained as the product of the uniform measure on a finite length interval with a codimension‐one base. As our two main applications, we consider the case when the base is the flat torus R2/2Z2$\mathbb {R}^2 / 2 \mathbb {Z}^2$ and the standard Gaussian measure
