Porthole to catalysis

A Porthole Into the Genetics of Congenital Heart Disease

In this issue of the Journal, Goodship and colleagues report results from an association study for common genetic variants underlying tetralogy of Fallot (TOF).1 By studying a limited number of single-nucleotide polymorphisms (SNPs) tagging haplotypes at 22 candidate genes, they associated a single SNP at a chromosome 12 locus harboring PTPN11, which encodes the protein tyrosine phosphatase SHP...

New Perspectives on Thiamine Catalysis: From Enzymic to Biomimetic Catalysis

This paper is a brief review of the detailed mechanism of action of thiamine enzymes, based on metal complexes of bivalent transition and post-transition metals of model compounds, thiamine derivatives, synthesized and characterized with spectroscopic techniques and X-ray crystal structure determinations. It is proposed that the enzymatic reaction is initiated with a V conformation of thiamine ...

Homogeneous Catalysis Homogeneous Catalysis

Approaches to single-nanoparticle catalysis.

Nanoparticles are among the most important industrial catalysts, with applications ranging from chemical manufacturing to energy conversion and storage. Heterogeneity is a general feature among these nanoparticles, with their individual differences in size, shape, and surface sites leading to variable, particle-specific catalytic activity. Assessing the activity of individual nanoparticles, pre...

Study on Catalysis of Cu-Fe Metal Composite Oxides to Thermal Decomposition Behavior of Bluestone

Nano-CuFe2O4 catalysts with different Cu/Fe molar ratios (CunFemO(n+1.5m)) were prepared by hydrothermal method. The thermal decomposition performance of CunFemO(n+1.5m) on CuSO4 were determined with TG-DSC method to evaluate its catalytic activity and the roasted product was characterized by ...
