To have a quantum-mechanical treatment we model a crystalline solid as
matter in which the atoms have long-range order, that is a recurring
(periodical) pattern of atomic positions that extends over many atoms.
We will describe the wavefunctions and energy levels of electrons in
such periodical atomic structures.

Physical chemistry is an unexpected shock to many university students. From the semi-
empirical approaches of the school laboratory, first year undergraduates suddenly find
themselves propelled into an unexpected quagmire of definitions and equations. Worse
still, although the applicability of the subject is sometimes obvious, studying the behavior
of a particle in an infinitely deep well can seem nothing short of farcical on first
The mathematical modeling of microstructures in solids is a fascinating topic
that combines ideas from different fields such as analysis, numerical simulation,
and materials science. Beginning in the 80s, variational methods have
been playing a prominent rˆole in modern theories for microstructures, and
surprising developments in the calculus of variations were stimulated by questions
arising in this context.
The extraordinary ability of the chemical element carbon to combine with itself
and other chemical elements in different ways is the basis of organic chemistry
and of life. This chemical versatility also gives rise to a rich diversity of
structural forms of solid carbon. This introductory chapter is an attempt to
survey the very wide range of carbon materials that is now available with
emphasis on chemical bonding and microstructure.
Most colleges and universities now have courses and degree programs related to
materials science. Materials Chemistry addresses inorganic, organic, and nanobased
materials from a structure vs. property treatment, providing a suitable breadth
and depth coverage of the rapidly evolving materials field in a concise format.
The enzymatic kinetics of glycoside hydrolase family 7 cellobiohydrolase
(Cel7A) towards highly crystalline celluloses at the solid–liquid interface
was evaluated by applying the novel concept of surface density (q) of the
enzyme, which is defined as the amount of adsorbed enzyme divided by the
maximum amount of adsorbed enzyme.
Solid state lasers include lasers based on paramagnetic ions, organic dye molecules, and
color centers in crystalline or amorphous hosts. Semiconductor lasers are included in this
section because they are a solid state device, although the nature of the active center—
recombination of electrons and holes—is different from the dopants or defect centers used in
other lasers in this category.
As we all know, ceramic materials are inorganic, non-metallic, solid, and inert
materials. Things are made from them by the action of heat and subsequent cooling,
which may be crystalline or partly crystalline. The definition of ceramic is often
restricted to inorganic crystalline materials, as opposed to the noncrystalline glasses,
which involve several steps of the ceramic process, and their mechanical properties
behave similarly to ceramic materials.

Production of nanoparticles from natural hydroxylapatite by laser ablation
Mohamed Boutinguiza*†, Rafael Comesaña†, Fernando Lusquiños†, Antonio Riveiro† and Juan Pou†
Abstract Laser ablation of solids in liquids technique has been used to obtain colloidal nanoparticles from biological hydroxylapatite using pulsed as well as a continuous wave (CW) laser.
Amorphous materials have attracted much attention in the last two decades. The
first reason for this is their potential industrial applications as suitable materials for
fabricating devices, and the second reason is the lack of understanding of many
properties of these materials, which are very different from those of crystalline
materials. Some of their properties are different even from one sample to another
of the same material.
