Authored by Elena Borisenko and Nikolai Kolesnikov,
this huge PDF is a comprehensive package on crystallization, especially dealing
with artificial and natural crystals. Important matters include analyses of
thermal barrier coatings, nucleation and crystal growth in phase-separated
glasses, and the development of novel metamaterials. The research paper has
further examined the influence of amino acid additives on ammonium dihydrogen
phosphate crystal growth. It further discusses the biomineralization process of
biological systems such as the special types of crystal formations within an
organism and then delves deeper into biomimetic crystallization techniques
whereby macromolecular additives are used along with the implications of crystal
growth for health protection. This resource is very useful for the researcher
and practitioner in materials science, offering insights into the complexities
of crystallization processes and their applications in high technology and
biomaterials.
X-ray crystallography
and the methods of structure determination. Its coverage-from crystallization to
diffraction techniques, and eventually to symmetry analysis-will tackle the
subject in a step-by-step and an organized manner that provides a clear insight
into complex matters. Some critical concepts include intramolecular and
intermolecular geometry, thermal motion analysis, and hydrogen bonding. It
covers very advanced topics, like powder diffraction and graph sets, making this
note a very valuable resource for students and researchers who conduct work in
crystallography. This note is very valuable because it offers practical insight
into the interpretation and validation of crystal structures that give those
seeking to deepen their knowledge in structural chemistry and material sciences
some incredible value.
