La revue Entropie offre un forum pour la publication de contributions originales et d’articles techniques complets de recherche interdisciplinaire et originale sur tous les thèmes autour de l’énergie, de son utilisation, et des processus de conversion, de thermodynamique (...)


Nanostructured silicon in a thermoelectric generator to reduce heat losses

In this paper, we present a planar thermoelectric microgenerator (μTEG) based on CMOS-compatible silicon technology to harvest all forms of thermal energy. These have made by using low cost, abundant and eco-friendly materials. The heat harvesting has performed with a silicon (...)


Exergy assessment of metabolic changes on life expectancy of smokers

A few authors have determined exergy behavior of human body under standard conditions. Some of these studies include estimate of life expectancy based on the association of entropy creation / exergy destruction and rate of living theory. Metabolism is known as the major (...)


First optimization approach of a solar Organic Rankine Cycle

This work presents a first optimisation approach based on Finite physical Dimensions Optimal thermodynamics - FDOT-. The optimisation approach is applied for an organic Rankine cycle activated by a solar loop. Consequently, the heat received by the solar collectors is (...)


The silent emergence of complexity in 3D printing

Invented in 1984 in a few days, the concept of additive manufacturing has been developed quickly enough to reach a global market of around 40 billion €/year with a 20% annual growth rate. Although the first technology was the space resolved polymerization of resins induced by (...)


Time and space arrows: an understanding of the second law of thermodynamics

The common formulations of the second law of thermodynamics link entropy and time in an almost exclusive way: "the entropy of an isolated system increases with time". This applies to both historical (Carnot, Clausius) and statistical (Boltzmann, Gibbs) formulations. This (...)
