Terminal Molybdenum Phosphides with d Electrons: Radical Character Promotes Coupling Chemistry

Chemistry and biology of the molybdenum cofactor.

Genetic and biochemical studies have established that in all molybdenum-containing enzymes, with the exception of nitrogenase, the metal is part of a complex called the molybdenum (Mo) cofactor (Johnson, 1980). The cofactor was originally characterized by its ability to reconstitute the apoprotein of the enzyme nitrate reductase in crude extracts of cells of the nif-l mutant of Neurospora crass...

Radical-Enhanced Chinese Character Embedding

We present a method to leverage radical for learning Chinese character embedding. Radical is a semantic and phonetic component of Chinese character. It plays an important role as characters with the same radical usually have similar semantic meaning and grammatical usage. However, existing Chinese processing algorithms typically regard word or character as the basic unit but ignore the crucial ...

Radiation chemistry: Radical water.

I onizing radiation is known to be harmful to living organisms because it creates reactive radicals and charged species. In particular, highly energetic X-rays that ionize by removing one of the innermost (core) electrons of an atom lead to a cascade of events that must be better characterized if we are to fully understand their toxic effects 1. Writing in Nature Chemistry, Petr Slavíček, Bernd...

Reduced Chemistry-Diffusion Coupling

In reacting flow problems involving large numbers of chemical species and reactions, reduced chemistry modeling is used to approximately describe, with fewer unknowns, the slow chemical evolutions after the rapid but brief initial transients have decayed. Diffusion transport terms, if present, are modified by the reduced chemistry approximations. This article reiterates that the use of unmodifi...
