High-Performance Tracking for Proton Exchange Membrane Fuel Cell System PEMFC Using Model Predictive Control
(MDPI, 2021-05-21)
Proton exchange membrane (PEM) fuel cell has recently attracted broad attention from many researchers due to its cleanliness, high efficiency and soundless operation. The obtention of high-performance output characteristics ...
Exemplary Ethical Communities. A New Concept for a Livable Anthropocene
(MDPI, 2021-05-17)
This article argues that we need to look at living examples provided by non-state communities in various regions of the world that are, perhaps unwittingly, contributing to the maintenance of the Earth’s optimal thermal ...
Soluble Salts Quantitative Characterization and Thermodynamic Modeling on Roman Bricks to Assess the Origin of Their Formation
(MDPI, 2021-05-12)
The environmental weathering and the formation of efflorescences on the brick walls are studied at the “Casa di Diana” Mithraeum at Ostia Antica archaeological site. Previous studies on subsoil, bedrock, hydrological systems ...
Parametric Optimization and Effect of Nano-Graphene Mixed Dielectric Fluid on Performance of Wire Electrical Discharge Machining Process of Ni55.8Ti Shape Memory Alloy
(MDPI, 2021-05-13)
In the current scenario of manufacturing competitiveness, it is a requirement that new technologies are implemented in order to overcome the challenges of achieving component accuracy, high quality, acceptable surface ...
Mindfulness and Next-Generation Members of Family Firms: A Source for Sustainability
(MDPI, 2021-05-11)
Family businesses are considered complex organizations where emotional and management challenges need to be faced. This is even more difficult when time of succession arrives and the new members are expected to engage with ...
The fate of carbon in a mature forest under carbon dioxide enrichment
(Springer Nature, 2020)
Atmospheric carbon dioxide enrichment (eCO2) can enhance plant carbon uptake and growth1 5, thereby providing an important negative feedback to climate change by slowing the rate of increase of the atmospheric CO2 ...
Improving collaboration between ecosystem service communities and the IPBES science-policy platform
(Taylor and Francis, 2020)
The end of the first working program of the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES) provided an opportunity to draw lessons from its work. This perspective paper captures ...
Evaluating integrated impacts of low-emission transitions in the livestock sector
(Elsevier, 2020)
This paper provides the results of a combined qualitative and quantitative assessment of key impacts for two low-emission transition pathways for the Dutch livestock sector. These impacts or side-effects can be positive ...
Predicting Dimensions in Microfluidic Paper Based Analytical Devices
(MDPI, 2020-12-26)
The main problem for the expansion of the use of microfluidic paper-based analytical devices and, thus, their mass production is their inherent lack of fluid flow control due to its uncontrolled fabrication protocols. To ...
Suppression of the Self-Nucleation Effect of Semicrystalline Polymers by Confinement
(ACS, 2021-04-15)
The melt memory effect is well-known in polymer crystallization. It is caused by self-nuclei that
persist above the melting temperature. The origin and physical nature of self-nuclei are still under
debate. In this work, ...
