We study charge and energy transfer in two-site molecular electronic junctions in which electron transport is assisted by a vibrational mode. To understand the role of mode harmonicity/anharmonicity in transport behavior, we consider two limiting situations: (i) the mode is assumed harmonic, (ii) we truncate the mode spectrum to include only two levels, to represent an anharmonic mode. Based on...

Advances in the fabrication and characterization of nanoscale systems now allow for a deeper understanding of one of the most basic issues in science and technology: the flow of energy at the microscopic level. This knowledge is also likely to impact our ability to build more efficient devices for energy generation, storage and conversion. In this Colloquium we survey recent advances and presen...

The aim of the study is to develop a design an air-heating recuperator for purge ventilation system building inbuilt purpose utilizing lower-grade heat from gases and emissions with associated production thermoelectricity. An experimental as part unit has been developed. It includes thermoelectric source electromotive difference, which operates result conversion into electricity, allows lower-p...
