Water-energy-food nexus and life cycle thinking: A new approach to environmental and nutritional assessment of potato chips
(MDPI, 2022-03-30)The water-energy-food (WEF) nexus has become a key concept to promote the cross-sectoral coordination toward sustainable development. In particular, understanding the interdependences of these pillars, as well as addressing ... -
Trends in research on energy efficiency in appliances and correlations with energy policies
(MDPI, 2022)According to the Intergovernmental Panel on Climate Change (IPCC) 5th Assessment report, energy-efficient appliances can reduce global electricity consumption even though there is an expected increase in the number and ... -
Bibliometric map on corrosion in concentrating solar power plants
(MDPI, 2022)Concentrating solar power (CSP), also known as solar thermal electricity (STE), is increasing its deployment worldwide. One of the potential ways to decrease costs in CSP plants is the improvement of corrosion resistance ... -
Exploring the feasibility of substituting mimosa tannin for pine bark powder. A LCA perspective
(2022)The use of vegetable tannins is a bio-based alternative to chrome tanning. The most used vegetable extracts are Mimosa and Quebracho. To improve the sustainability of the tanning process, a chemically unmodified pine bark ... -
Experimental steady-state and transient thermal performance of materials for thermal energy storage in building applications: From powder SS-PCMs to SS-PCM-based acrylic plaster
(Elsevier, 2022)Thermal performance of SS-PCM composites, simulating building envelope conditions, is difficult to asset with traditional laboratory equipment. However, in this work, the evaluation of three SS-PCM based on eutectic fatty ... -
A queuing theory model for fog computing
(Springer, 2022)Under many scenarios where resources may be scarce or a good Quality of Service is a requirement, appropriately sizing components and devices is one of the main challenges. New scenarios, such as IoT, mobile cloud computing, ... -
Experimental Assessment of the Influence of the Design on the Performance of Novel Evaporators with Latent Energy Storage Ability
