Alkene Hydrogenation by a Cationic, Nine-Coordinate Molybdenum(VI) Pentahydride Catalyst. [PDF]

open access: yesChemistry
While late 3d metals dominate efforts to replace precious metals in homogeneous hydrogenation, molybdenum has remained largely ignored. This work reveals that a nine‐coordinate pentahydrido molybdenum complex can hydrogenate a broad range of alkenes efficiently, demonstrating that early‐metal polyhydrides can serve as genuine catalysts rather than mere

Pd/C-Catalyzed Hydrogenation of CF<sub>3</sub>-, CF<sub>2</sub>H-, and CF<sub>2</sub>CO<sub>2</sub>Et-containing Pyridines: A Robust Method for Highly Functionalized containing Piperidines. [PDF]

open access: yesAngew Chem Int Ed Engl
A robust and efficient method to access diversely functionalized fluorinated piperidines was developed. The approach features the hydrogenation of polysubstituted pyridines bearing CF3, CF2H, and CF2CO2Et substituents using an inexpensive, readily available heterogeneous Pd/C catalyst under air‐ and moisture‐tolerant conditions, offering an appealing ...

Positioning Incretin-Based and Next-Generation Obesity Management Medications: A Methodological Framework for a Series of Systematic Reviews and Network Meta-Analyses. [PDF]

open access: yesDiabetes Obes Metab
ABSTRACT Background The obesity pharmacotherapy landscape is evolving rapidly, with several approved incretin‐based therapies and an expanding pipeline of investigational compounds targeting multiple metabolic pathways. Conventional evidence syntheses often struggle to accommodate differences in dose selection, treatment duration and stage of clinical ...

Hilbert-Haar coordinates and Miranda's theorem in Lie groups

open access: yesBruno Pini Mathematical Analysis Seminar, 2020
We study the interior regularity of solutions to a class of quasilinear equations of non-degenerate p-Laplacian type on Lie groups that admit a system of Hilbert-Haar coordinates. These are coordinates with respect to which every linear function has zero

A Cornucopia of Carnot Groups in Low Dimensions

open access: yesAnalysis and Geometry in Metric Spaces, 2022
Stratified groups are those simply connected Lie groups whose Lie algebras admit a derivation for which the eigenspace with eigenvalue 1 is Lie generating.

DFT screening of adsorption of biodiesel molecules on aluminum and stainless steel surfaces

open access: yesResults in Surfaces and Interfaces, 2022
We present a Density Functional Theory (DFT) study of the adsorption of small organic molecules, taken as models of biodiesel autoxidation products, on stainless steel and aluminum surfaces.

Nature and importance of follicular lymphoma precursors

open access: yesHaematologica, 2014
It is now widely recognized that cancer development is a protracted process requiring the stepwise acquisition of multiple oncogenic events. In humans, this process can take decades, if not a lifetime, blurring the notion of ‘healthy’ individuals ...

On Viscosity and Equivalent Notions of Solutions for Anisotropic Geometric Equations

open access: yesAbstract and Applied Analysis, 2020
We prove that viscosity solutions of geometric equations in step two Carnot groups can be equivalently reformulated by restricting the set of test functions at the singular points.

Nonexistence Results for Semilinear Equations in Carnot Groups

open access: yesAnalysis and Geometry in Metric Spaces, 2013
In this paper, following [3], we provide some nonexistence results for semilinear equations in the the class of Carnot groups of type ★.This class, see [20], contains, in particular, all groups of step 2; like the Heisenberg group, and also Carnot ...
