Abstract This chapter discusses transport data on Ce- and Yb-based strongly correlated thermoelectric materials, in both the high-temperature regime, including pressure and doping dependences, and the low-temperature, Fermi liquid state. Heavy fermions and valence fluctuators at high temperature are modeled theoretica…

This chapter presents a compact introduction to density functional theory (DFT) and the standard approximations used in practical applications (local density and generalized gradient approximations, LDA and GGA). Improved treatments of the electronic excitations in weakly correlated semiconductors (GW method) and stro…
This chapter proves the Jonson-Mahan theorem, which is a generalization of the result for noninteracting systems that all transport coefficients can be derived from integrals over frequency ω of a single transport function multiplied by different powers of ω. The Jonson-Mahan theorem extends this to many-body systems…
Das Ziel der vorliegenden Arbeit ist die Entwicklung eines Verfahrens zur zerstörungsfreien Quantifizierung von Elementtiefengradienten in Cu(In,Ga)Se2-Dünnschichten, die als Absorber von Dünnschichtsolarzellen verwendet werden. Die entwickelte Quantifizierungsmethode nutzt den Ansatz der fundamentalparameterbasierete…
This chapter starts with a solution of the Domenicali equation, which embodies energy conservation in the steady state, for the simple case of constant material parameters σ, κ, and α. rom the solutions obtained with different boundary conditions, the parameters that serve to characterize the quality of thermoelectric…
This chapter starts with a description of the effect of an external magnetic field on the orbital degrees of freedom of the electrons responsible for transport. The action of the Lorentz force on flowing charges is considered, and the Hall, Nernst, Ettinghausen, and Righi-Leduc effects are derived. On the other hand,…
This chapter describes how, in a thermoelectric sample attached to reservoirs in different thermodynamic states, the charge and energy distributions are nonuniform, and currents flow to establish a state of thermodynamic equilibrium for the whole system (sample plus reservoirs). The dissipative processes accompanying…
Protein adsorption at interfaces is of great relevance in industry and medicine. The growth of biofilms at interfaces is strongly influenced by adsorbed proteins. The control of this biofilm formation is necessary for technical and medical applications. Fundamental mechanisms of protein adsorption at solid/liquidand l…

This grant provided partial support for the National Research Council’s (NRC) decadal survey of nuclear physics. This is part of NRC’s larger effort to assess and discuss the outlook for different fields in physics and astronomy, Physics 2010, which takes place approximately every ten years. A report has been prepared…
در تولید کاغذهای بستهبندی، خصوصا هنگامی که از خمیرهای مکانیکی یا کاغذ بازیافت شده و ساخته شده از چوب استفاده میشود، مقدار زیادی از مواد محلول و کلوئیدی ( DCS ) که عمدتا از همیسلولزها، مواد استخراجی و لیگنانها تشکیل شده است از خمیر آزاد شده و در آب فرآیندی، پراکنده یا حل میشوند. تجمع DCS طی عملیات کاغذسازی به دلی…
A utilização de revestimentos duros possui inúmeras aplicações na indústria metal-mecânica devido à melhora das propriedades da superfície tais como aumento da dureza, da resistência ao desgaste e à corrosão. Uma das técnicas que vem sendo utilizada na indústria é a PVD por magnetron sputtering. O presente trabalho es…
