Cooperative catalysis by silica-supported organic functional groups [PDF]
Chemical Society Reviews, 2008 Hybrid inorganic–organic materials comprising organic functional groups tethered from silica surfaces are versatile, heterogeneous catalysts. Recent advances have led to the preparation of silica materials containing multiple, different functional groups

Functional Calculus on Non-Homogeneous Operators on Nilpotent Groups [PDF]
, 2020 We study the functional calculus associated with a hypoelliptic left-invariant differential operator $\mathcal{L}$ on a connected and simply connected nilpotent Lie group $G$ with the aid of the corresponding \emph{Rockland} operator $\mathcal{L}_0$ on ...

Moment Functions on Groups [PDF]
Results in Mathematics, 2021 AbstractIn this paper generalized moment functions are considered. They are closely related to the well-known functions of binomial type which have been investigated on various abstract structures. The main purpose of this work is to prove characterization theorems for generalized moment functions on commutative groups.
