Cooperative catalysis by silica-supported organic functional groups [PDF]
, 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

Duke Mathematical Journal, 1995 Let \(K = \mathbb{Q}(\sqrt{-D})\) be an imaginary quadratic field with class number \(h\), and let \(\chi\) be any one of the \(h\) characters of the class group of \(K\). Then the class group \(L\)-functions \(L_K (s,\chi)\) are defined as natural generalizations of the Dedekind zeta-function.

Synthesis of biodegradable polyesteramides with pendant functional groups [PDF]
, 1992 Morpholine-2,5-dione derivatives having substituents with benzyl-protected carboxylic acid, benzyloxycarbonyl-protected amine and p-methoxy-protected thiol groups, respectively, were prepared in 29-58% yield by cyclization of the corresponding N-[(2RS ...

Global functional calculus for operators on compact Lie groups [PDF]
, 2014 In this paper we develop the functional calculus for elliptic operators on compact Lie groups without the assumption that the operator is a classical pseudo-differential operator. Consequently, we provide a symbolic descriptions of complex powers of such

Functional and isoperimetric inequalities for probability measures on H-type groups [PDF]
, 2011 We investigate isoperimetric and functional inequalities for probability measures in the sub-elliptic setting and more specifically, on groups of Heisenberg type.

High functional diversity is related to high nitrogen availability in a deciduous forest - evidence from a functional trait approach [PDF]
, 2010 The current study tested the assumption that floristic and functional diversity patterns are negatively related to soil nitrogen content. We analyzed 20 plots with soil N-contents ranging from 0.63% to 1.06% in a deciduous forest near Munich (Germany ...

Using an affinity analysis to identify phytoplankton associations
Ecology and Evolution, 2022 Phytoplankton functional traits can represent particular environmental conditions in complex aquatic ecosystems. Categorizing phytoplankton species into functional groups is challenging and time‐consuming, and requires high‐level expertise in species ...
