KEY FEATURES:
A unified, fundamental and quantitative resource. The result of 5
years of investigation from researchers around the world
New data from a range of new techniques, including synchrotron
radiation X-ray topography provide safer and surer methods of
identifying deformation mechanisms
Informing the future direction of research in intermediate and high
temperature processes by providing original treatment of
dislocation climb
DESCRIPTION:
"Thermally Activated Mechanisms in Crystal Plasticity is a
unified," quantitative and fundamental resource for material
scientists investigating the strength of metallic materials of
various structures at extreme temperatures. Crystal plasticity is
usually controlled by a limited number of elementary dislocation
mechanisms, even in complex structures. Those which determine
dislocation mobility and how it changes under the influence of
stress and temperature are of key importance for understanding and
predicting the strength of materials. The authors describe in a
consistent way a variety of thermally activated microscopic
mechanisms of dislocation mobility in a range of crystals. The
principles of the mechanisms and equations of dislocation motion
are revisited and new ones are proposed. These describe mostly
friction forces on dislocations such as the lattice resistance to
glide or those due to sessile cores, as well as dislocation
cross-slip and climb. They are critically assessed by comparison
with the best available experimental results of microstructural
characterization, in situ straining experiments under an electron
or a synchrotron beam, as well as accurate transient mechanical
tests such as stress relaxation experiments. Some recent attempts
at atomistic modeling of dislocation cores under stress and
temperature are also considered since they offer a complementary
description of core transformations and associated energy
barriers.
In addition to offering guidance and assistance for further
experimentation, the book indicates new ways to extend the body of
data in particular areas such as lattice resistance to glide.
This is a new release of the original 1938 edition.

Traditionally mycotoxins are mainly determined by immunoassay
screening methods or by single compound chromatographic analytical
methods, based on immunoaffinity column cleanup followed by a
separation step using thin layer chromatography (TLC), gas
chromatography (GC) or liquid chromatography (LC), which were
coupled to conventional detectors such as electron capture
detection (ECD), fluorescence or UV-visible detection. In some
cases, especially when fluorescence detection was used, it was
necessary to include a pre- or post-column derivatisation step in
order to increase the detection capabilities of the analytical
method. However, the application of hyphenated chromatographic
techniques, especially LC coupled to mass spectrometry (MS) and
LC-MS/MS, has several advantages including simple treatment, due to
further clean up procedures with immunoaffinity columns can be
avoided, rapid determination and high sensitivity.
This book describes the most relevant information related to the
chromatographic determination of veterinary drug residues in food,
environmental and biological samples, providing the main
applications performed in this type of matrices, as well as the
main advances related to the chromatographic techniques.
