Degradation of components and structures by fatigue

Journal of Nondestructive Evaluation, 1996
This note examines briefly fatigue as a degradation mechanism and how engineers compensate for the fatigue phenomenon. Design is generally based on the stress-lifetime concept, but this concept is not very useful for lifetime assessment of operating components; thus, fatigue crack initiation and the growth of fatigue cracks become important.

Dopamine-degrading enzyme structure

C&EN Global Enterprise, 2016
A first glimpse of the three-dimensional structure of the human enzyme that converts the neurotransmitter dopamine to norepinephrine comes courtesy of X-ray crystallography and a team led by Hans E...

On the Degradation of Concrete in Marine Structures

1985
Concrete is a cheap and extremely handy material and as such used extensively also in marine structures. Everybody dealing with this material knows examples of concrete apparently of almost infinite durability but also examples where serious degradation started shortly after completion of the structure.

The Synthesis, Degradation, and Structure of Polyphosphazenes.

1978
Abstract : Poly(organophosphazenes) and their cyclic oligomeric analogs have been used as ligands for transition metal complexes. X-Ray structural work has shown that platinum binds to the skeleton of specific organophosphazenes. X-Ray structural work and conformational energy calculations have been used to deduce the relationships between structure ...
