ChemInform Abstract: Amorphous Alloys as Catalysts or Catalyst Precursors
ChemInform, 1987The application of amorphous alloys in catalysis has been investigated. Recent information is reviewed in terms of the advantages and disadvantages of amorphous alloys, especially with pre-treatment.

Metallodendrimers as Transphosphorylation Catalysts
Journal of the American Chemical Society, 2007The ZnII complexes of triazacyclononane-functionalized DAB dendrimers are powerful catalysts for the cleavage of an RNA model substrate with clear evidence of cooperativity between two metal centers.

Design of Catalysts and Catalyst Libraries
2000Combinatorial chemistry [1] and high-throughput screening are now reasonably well-validated for drug discovery; we have the ‘proofs of concept’ in terms of accelerated discovery and activity optimization, with compounds, for example from Pharmacopeia’s own programs, now at pre-clinical stages.

The utilisation of wool as a catalyst and as a support for catalysts
Applied Catalysis A: General, 2017Abstract Textiles are an emerging class of support material for catalysts, and are available in many different structures at a modest cost from a well-established industry. This review discusses 87 studies of wool and reconstituted wool as catalysts, and supports for catalysts, along with informative complementary studies.

Model Catalysts: Simulating the Complexities of Heterogeneous Catalysts
Annual Review of Physical Chemistry, 2012Surface-science investigations have contributed significantly to heterogeneous catalysis in the past several decades. Fundamental studies of reactive systems on metal single crystals have aided researchers in understanding the effect of surface structure on catalyst reactivity and selectivity for a number of important reactions. Recently, model systems,

Aerogels are often largely mesoporous solids, with a porosity which may exceed 90 vol% and a specific surface area up to 1000 m2 g-1. Such materials were first obtained by Kistler in 1932, and designate gels in which the liquid was replaced with a gas without collapsing the gel solid network. Contrary to xerogels dried from wet gels by evaporation with

Introduction The past few years have been heady times for RNA aficionados. The successive discoveries of introns, catalytic RNA, and RNA editing have fundamentally changed our conception of the functionality of macromolecules and the manner in which genetic information is expressed.
