Book Description
The electrodeposition process has been the standard method for producing actinide and lanthanide thin films for decades. The major benefits of the technique include high reproducibility, simple equipment set up, and high material utilization. The latter is important when producing actinide thin films of rare materials, which is the case for many actinide thin film targets for Super Heavy Element (SHE) research. Many techniques besides electrodeposition have been used for non-radioactive lanthanides and have shown to be most useful for radioactive lanthanides as well as enriched stable lanthanides due to the amount of available material. Despite its use for several decades, there is still a significant amount that is unknown about the actinide electrodeposition process. Consequently, it has become apparent that a deeper understanding of the electrodeposition process is necessary to produce films with improved properties. For example, greater adhesion could increase the lifetime of thin film targets irradiated on high current particle accelerators. For this reason, there are ongoing efforts to gain an understanding of the actinide electrodeposition process utilizing in-situ characterization techniques of lanthanide depositions. For rare actinide thin films, a lanthanide surrogate is desired to understand the morphology of the deposited material without depleting the amount of the rare actinide desired. This master’s thesis project will focus on the development of optical spectroscopy techniques for online monitoring of the electrodeposition process as well as address the proposed chemical form for the deposition of a lanthanide, and in turn, actinide electrodeposition

Book Description
This book has been designed to cover the syllabus of Inorganic Chemistry required for the B.Sc./B.Sc. Hons./M.Sc. students of the various Universities. I have compelled all the questions asked so far in different universities as well as C.C.S. University Meerut. I have arranged the subject matter in a continuous manner. Special emphasis has been laid on fundamental concept of the topics. Care has been taken to make the treatment of the subject simple and accessible to the average students. The gradation of the solved and unsolved questions has been facilitated from simple to difficult. It is believed that the book in the present form will be found to be useful by the student community and the teaching fraternity alike. Contents: Lanthanides (4f-Block Series), Fuels and Furnaces, Precipitation from Homogeneous Medium, Actinides (5F-Block Elements).

Book Description
Simultaneous observation of electrochemical and spectroscopic properties (spectroelectrochemistry) at optically transparent electrodes (OTE's) was used to study some less stable oxidation states of selected lanthanide and actinide elements. Cyclic voltammetry at microelectrodes was used in conjunction with spectroelectrochemistry for the study of redox couples. Additional analytical techniques were used. The formal reduction potential (E/sup 0/') values of the M(III)/M(II) redox couples in 1 M KCl at pH 6 were -0.34 +- 0.01 V for Eu, -1.18 +- 0.01 V for Yb, and -1.50 +- 0.01 V for Sm. Spectropotentiostatic determination of E/sup 0/' for the Eu(III)/Eu(II) redox couple yielded a value of -0.391 +- 0.005 V. Spectropotentiostatic measurement of the Ce(IV)/Ce(III) redox couple in concentrated carbonate solution gave E/sup 0/' equal to 0.051 +- 0.005 V, which is about 1.7 V less positive than the E/sup 0/' value in noncomplexing solution. This same difference in potential was observed for the E/sup 0/' values of the Pr(IV)/Pr(III) and Tb(IV)/Tb(III) redox couples in carbonate solution, and thus Pr(IV) and Tb(IV) were stabilized in this medium. The U(VI)/U(V)/U(IV) and U(IV)/U(III) redox couples were studied in 1 M KCl at OTE's. Spectropotentiostatic measurement of the Np(VI)/Np(V) redox couple in 1 M HClO/sub 4/ gave an E/sup 0/' value of 1.140 +- 0.005 V. An E/sup 0/' value of 0.46 +- 0.01 V for the Np(VII)/Np(VI) couple was found by voltammetry. Oxidation of Am(III) was studied in concentrated carbonate solution, and a reversible cyclic voltammogram for the Am(IV)/Am(III) couple yielded E/sup 0/' = 0.92 +- 0.01 V in this medium; this value was used to estimate the standard reduction potential (E/sup 0/) of the couple as 2.62 +- 0.01 V. Attempts to oxidize Cm(III) in concentrated carbonate solution were not successful which suggests that the predicted E/sup 0/ value for the Cm(IV)/Cm(III) redox couple may be in error.

Book Description
Comprehensive Inorganic Chemistry II, Nine Volume Set reviews and examines topics of relevance to today’s inorganic chemists. Covering more interdisciplinary and high impact areas, Comprehensive Inorganic Chemistry II includes biological inorganic chemistry, solid state chemistry, materials chemistry, and nanoscience. The work is designed to follow on, with a different viewpoint and format, from our 1973 work, Comprehensive Inorganic Chemistry, edited by Bailar, Emeléus, Nyholm, and Trotman-Dickenson, which has received over 2,000 citations. The new work will also complement other recent Elsevier works in this area, Comprehensive Coordination Chemistry and Comprehensive Organometallic Chemistry, to form a trio of works covering the whole of modern inorganic chemistry. Chapters are designed to provide a valuable, long-standing scientific resource for both advanced students new to an area and researchers who need further background or answers to a particular problem on the elements, their compounds, or applications. Chapters are written by teams of leading experts, under the guidance of the Volume Editors and the Editors-in-Chief. The articles are written at a level that allows undergraduate students to understand the material, while providing active researchers with a ready reference resource for information in the field. The chapters will not provide basic data on the elements, which is available from many sources (and the original work), but instead concentrate on applications of the elements and their compounds. Provides a comprehensive review which serves to put many advances in perspective and allows the reader to make connections to related fields, such as: biological inorganic chemistry, materials chemistry, solid state chemistry and nanoscience Inorganic chemistry is rapidly developing, which brings about the need for a reference resource such as this that summarise recent developments and simultaneously provide background information Forms the new definitive source for researchers interested in elements and their applications; completely replacing the highly cited first edition, which published in 1973

Book Description
LANTHANIDE AND ACTINIDE CHEMISTRY Lanthanides and actinides, also known as “f elements,” are a group of metals which share certain important properties and aspects of electronic structure. They have a huge range of applications in the production of electronic devices, magnets, superconductors, fuel cells, sensors, and more. The cursory treatment of these important metals in most inorganic chemistry textbooks makes a book-length treatment essential. Since 2006, Lanthanide and Actinide Chemistry has met this need with a thorough, accessible overview. With in-depth accounts of the lanthanides, actinides, and transactinides, this book is ideal for both undergraduate and postgraduate students in inorganic chemistry or chemical engineering courses. Now updated to reflect groundbreaking recent research, this promises to continue as the essential introductory volume on the subject. Readers of the second edition of Lanthanide and Actinide Chemistry will also find: New and expanded subject areas including lanthanide enzymes, single-molecule magnets, luminescence and upconversion, organometallic and coordination chemistry; and many more. Up-to-date information on the myriad modern applications of f-elements Lists of objectives and learning goals at the start of each chapter Lanthanide and Actinide Chemistry is ideal for advanced undergraduates and graduate students in f-element chemistry, inorganic chemistry, or any related field. INORGANIC CHEMISTRY ADVANCED TEXTBOOK This series reflects the pivotal role of modern inorganic and physical chemistry in a whole range of emerging areas, such as materials chemistry, green chemistry and bioinorganic chemistry, as well as providing a solid grounding in established areas such as solid state chemistry, coordination chemistry, main group chemistry and physical inorganic chemistry.
