(2019-08-21)
Background & objectives: Trypanosoma cruzi, the causative agent of American trypanosomiasis, has been reported in 180 mammalian species and 154 triatomines species of Neotropic. This is a clonal parasite with variable ...
Activated carbon from cassava peel: a promising electrode material for supercapacitors
(2019-08-10)
Supercapacitors are conventional devices in electrical circuits that produce electrical pulses at high power levels in short periods. Electrodes for supercapacitors were prepared with activated carbon. Activated carbon was ...
Thermoeconomic modelling and parametric study of a simple orc for the recovery ofwaste heat in a 2 MW gas engine under differentworking fluids
(2019-10-25)
This paper presents a thermo-economic analysis of a simple organic Rankine cycle (SORC)
as a waste heat recovery (WHR) systems of a 2 MW stationary gas engine evaluating different
working fluids. Initially, a systematic ...
Evaluation of the energy recovery potential of thermoelectric generators in diesel engines
(2019-09-12)
Thermoelectric generation is an alternative to recover some of the wasted energy trough an exhaust of
the internal combustion engines. This paper assesses the performance of a thermoelectric generator with
20 modules by ...
