Advances in the flavonoid field have been nothing short of
spectacular over the last 20 years. While the medical field has
noticed flavonoids for their potential antioxidant, anticancer and
cardioprotectant characteristics, growers and processors in plant
sciences have utilized flavonoid biosynthesis and the genetic
manipulation of the flavonoid pathway in plants to improve the
nutritional and ornamental value of crops. Flavonoids: Chemistry,
Biochemistry and Applications covers each class of flavonoid and
presents the historic advances made in flavonoid research since the
1994 publication of an earlier text, Flavonoids Advances in
Research Since 1986. This book details the analytical techniques
scientists have used to achieve an improved understanding of
flavonoid structures and functions as well as advances in the
genetic manipulation of the flavonoid pathway, and the discovery of
many new flavonoids. It indicates which techniques are best suited
for the isolation and structure determination of flavonoids and
whether the structures are novel. While explaining how to evaluate
the flavonoid content in food and beverages, the book reveals the
biotechnological advances that have allowed nutritionists and plant
physiologists to assess the possible effects of flavonoids. As
interest regarding the impact and health benefits of flavonoids
continues to grow, Flavonoids: Chemistry, Biochemistry and
Applications reflects the continuing commitment of flavonoid
researchers to the improvement of human health and provides the
most comprehensive, up-to-date source of information for all known
flavonoids.

Nanocrystalline materials is the name given to three-dimensional ultrafine, polycrystalline microstructures. These microstructures give rise to chemical and physical size effects which are of increasing scientific and technological interest. This book describes the development of a chemical vapor synthesis method for the production of nanocrystalline ceramic powders. The development of the microstructure during sintering is studied and the influence of the synthesis parameters on the structure and properties of the nanocrystalline ceramics from the atomic to the microstructural level is investigated. The emerging unified view, from powder synthesis and ceramic processing to structural characterization and determination of properties, provides a detailed understanding of nanocrystalline materials and enables a precise control of the quality of the final products.

It has been a decade since two seminal reviews demonstrated that
mixed-valence compounds share many unique and fascinating features.
The insight pro vided by those early works has promoted a great
deal of both experimental and theoretical study. As a result of
extensive efforts, our understanding of the bonding and properties
of mixed-valence compounds has advanced substantially. There has
been no compre hensive treatment of mixed-valence compounds since
1967, and the meeting convened at Oxford in September, 1979,
provided a unique opportunity to examine the subject and its many
ramifications. Mixed-valence compounds play an important role in
many fields. Although the major impact of the subject has been in
chemistry, its importance has become increasingly clear in solid
state physics, geology, and biology. Extensive interest and effort
in the field of molecular metals has demonstrated that
mixed-valency is a prerequisite for high elec trical conductivity.
The intense colors of many minerals have been shown to be due to
mixed-valency, and the electron-transfer properties of certain
mixed-valence metalloproteins are important in biological
processes. Experts from all of these areas participated in this
meeting, and the truly interdisciplinary nature of the subject made
it a unique learning experience for all in attendance."

When, forty years ago, as a student of Charles Coulson in Oxford I
began work in theoretical chemistry, I was provided with a
Brunsviga calculator-a small mechanical device with a handle for
propulsion, metal levers for setting the numbers, and a bell that
rang to indicate overflow. What has since come to be known as
computational chemistry was just beginning. There followed a long
period in which the fundamental theory of the "golden age"
(1925-1935) was extended and refined and in which the dreams of the
early practitioners were gradually turned into hard arithmetic
reality. As a still-computing survivor from the early postwar days
now enjoying the benefits of unbelievably improved hardware, I am
glad to contribute a foreword to this series and to have the
opportunity of providing a little historical perspective. After the
Brunsviga came the electromechanical machines of the late 1940s and
early 1950s, and a great reduction in the burden of calculating
molecular wavefunctions. We were now happy. At least for systems
con taining a few electrons it was possible to make fully ab initio
calculations, even though semiempirical models remained
indispensable for most molecules of everyday interest. The 1950
papers of Hall and of Roothaan represented an important milestone
along the road to larger-scale non empirical calculations,
extending the prewar work of Hartree and Fock from many-electron
atoms to many-electron molecules-and thus into "real chemistry."
There is probably no woman scientist more famous than Marie Curie
(1867-1934). She made one of the most important theoretical
breakthroughs of the twentieth century when she postulated that
radiation was an atomic rather than a chemical property, an
important milestone in understanding the structure of matter. Not
only did she coin the term radioactivity, but her painstaking
research culminated in the isolation of two new elements, polonium
and radium. For her achievements she won two Nobel Prizes, one in
physics (in 1903) and the other in chemistry (in 1911). This
informative, accessible, and concise biography looks at Marie Curie
not just as a dedicated scientist but also as a complex woman with
a sometimes-tumultuous personal life. This historian of science
describes Curie's life and career, from her early years in Poland,
where she was born Maria Sklodowska; through her marriage to and
collaboration with Pierre Curie; her appointment as the first
female professor at Sorbonne University after his untimely death;
and the scientific work that led to her recognition by the Nobel
Prize committee. The author also candidly discusses the controversy
that surrounded Marie when detractors charged that her work was
actually performed by her late husband. Finally, she describes
Curie's work in founding the radium institutes to study radiation
and in establishing mobile X-ray units during World War I.
Eventually, her long exposure to radium led to her death from
aplastic anemia in 1934. A year later, Albert Einstein published a
tribute to her in memoriam, praising both her intuition and her
tenacity under the most trying circumstances.
Ogilvie's appealing narrative brings the brilliant scientist and
courageous woman to life in a story that will continue to inspire
future scientists.
