Springer The Craft of Scientific Presentations
Book SynopsisIntroduction.- Speech: The Words You Say.- Structure: The Strategy You Choose.- Visual Aids: Your Supporting Cast.- Delivery: You, the Room, and the Audience.- Conclusion: Aim High.Trade ReviewFrom the reviews of the second edition:“Alley’s book as an important and must-read guide for anyone in the scientific field. Professors, researchers and students will greatly benefit from Alley’s work. The book also has the benefit of being short and concrete–a plus for the busy scientist.” (Philosophy, Religion and Science Book Reviews, bookinspections.wordpress.com, March, 2014)“The second edition ... of this readable and informative volume highlights 13 critical errors to avoid in scientific presentations. Alley (Virginia Tech) provides examples through words and images about how to best convey ideas and meaning by understanding, connecting with, and engaging the audience. … This is a valuable work for academic and research libraries supporting, in particular, faculty, researchers, and graduate students. Summing Up: Highly recommended. Upper-level undergraduates through researchers/faculty.” (J. Clemons, Choice, Vol. 51 (5), January, 2014)Table of ContentsIntroduction.- Speech: The Words You Say.- Structure: The Strategy You Choose.- Visual Aids: Your Supporting Cast.- Delivery: You, the Room, and the Audience.- Conclusion: Aim High.

Springer-Verlag Berlin and Heidelberg GmbH & Co. KG Photoferroelectrics
Book SynopsisSince Valasek's discovery of the ferroelectric properties of Rochelle salt nearly 60 years ago, ferroelectricity has been regarded as one of the tradi- tional branches of dielectric physics. It has had important applications in lattice dynamics, quantum electronics, and nonlinear optics. The study of electron processes in ferroelectrics was begun with VUL's investigations of the ferroelectric properties of barium titanate [1.1]. In- trinsic and extrinsic optical absorption, band structure, conductivity and photoconductivity, carrier mobility. and transport mechanisms were examined in this compound, and in other perovskite ferroelectric semiconductors. An important discovery was that of the highly photosensitive photoconducting ferroelectrics of type AVBVICVIII (e.g. SbSI) by MERZ et al. in 1962 [1.2,3]. A large number of ferroelectric semiconductors (some photosensitive, some not) are now known, including broad-band materials (e.g. lithium niobate, lithium tantalate, barium and strontium niobate, and type-A~B~I compounds), BI and narrow-band semiconductors (e.g. type_AIVB compounds). A series of improper ferroelectric semiconductors and photosensitive ferroelastics have been discovered, of which Sb 0 I is an example. s 7 Owing to the uncertainty of their band structure, the difficulty in deter- mining the nature of the levels, the complexity of alloying, and their gen- erally low mobility values, ferroelectrics are rarely of interest regarded as nonlinear semiconductors. The most fruitful approach has been the study of the influence of electrons (especially nonequilibrium electrons) and electron excitations on phase transitions and ferroelectric properties. A large group of phenomena have recently been discovered and investigated.Table of Contents1. Introduction.- 2.
