Moliterni's research while affiliated with Università Campus Bio-Medico di Roma and other places

... On the other hand, to use a universal and rigorous approach from a thermodynamic point of view, many works in the literature adopt the "exergy" (or II law) efficiency, defined as the ratio between the least work of separation (minimum reversible work) and the actual work required [28][29][30]. Figure 1 depicts the conversion of heat into power through a Carnot Engine operating between the heat source at the hot temperature T H and the sink at the lowest temperature of the system (or the reference environment temperature) T 0 , as postulated by the MIT group [30]. The black box HDH receiving the separation work as mechanical (or electrical) energy and thermal energy that, according to the methodology proposed by Narayan et al. [30], can be converted into equivalent separation work through enthalpy and entropy, balances around the open system represented by the HDH separation block. ...
