Optical and tribo-mechanical characterization in metal-ceramic multilayers coatings
(Revista Mexicana de FisicaMéxico, 2020-08)Laboratory scale studies of tribological properties of nitride coatings are useful in predicting their protective wear behavior in cutting toolsfor industrial-scale applications. The main aim of this research is to determine ... -
Influence of droplet collision modelling in Euler/Lagrange calculations of spray evolution
(ResearchGate, 2020-07)The numerical computation of spraying systems is favourably conducted by applying the Euler/Lagrange approach. Although sprays downstream of the breakup region are very often rather dilute, droplet collisions may still ... -
Effect of extrusion screw speed and plasticizer proportions on the rheological, thermal, mechanical, morphological and superficial properties of PLA
(Multidisciplinary Digital Publishing Institute. MDPI, 2020-09-16)One of the critical processing parameters—the speed of the extrusion process for plasticized poly (lactic acid) (PLA)—was investigated in the presence of acetyl tributyl citrate (ATBC) as plasticizer. The mixtures were ... -
Industrial decarbonization by a new energy baseline methodology. Case study
(MDPIBasel, Switzerland, 2020-03-04)The main target of climate change policies in the majority of industrialized countries is to reduce energy consumption in their facilities, which would reduce the carbon emissions that are generated. Through this idea, ... -
