Nanochemistry and supramolecular chemistry of actinides and lanthanides: Problems and prospects

The possibility of using unique properties of lanthanides in the nanotechnology is demonstrated. The origination of linear and nonlinear optical properties of lanthanide compounds with phthalocyanines, porphyrins, naphthalocyanines, and their analogs in solutions and condensed state and the prospects of obtaining novel materials on their basis are discussed. Based on the electronic structure and properties of lanthanides and their compounds, namely, optical and magnetic characteristics, electronic and ionic conductivity, and fluctuating valence, molecular engines are classified. High-speed storage engines or memory storage engines; photoconversion molecular engines based on Ln(II) and Ln(III); electrochemical molecular engines involving silicate and phosphate glasses; molecular engines whose operation is based on insulatorsemiconductor, semiconductor-metal, and metal-superconductor types of conductivity phase transitions; solid electrolyte molecular engines; and miniaturized molecular engines for medical analysis are distinguished. It is shown that thermodynamically stable nanoparticles of Ln _x M _y composition can be formed by d elements of the second halves of the series, i.e., those arranged after M = Mn, Tc, and Re. Prospects of using lanthanide superconductors in nanotechnology are considered.

Visualization and Animation in Manufacturing and Materials

Scientific visualization is the application of modern techniques in computer graphics to make the results of science and engineering studies more effective. Visualization allows the researcher to take in a large quantity of data at a single glance, developing an understanding of the data and the relationship between factors that would be difficult to obtain with a more conventional presentation. The addition of animation provides even greater power, enabling one to better understand the changes that occur over time.
