Firm Size and the Business Model for Sustainable Innovation
Companies innovate towards sustainability because this may allow them to improve both their socio-environmental and economic performance. Firms that lead the way evolve towards a sustainable business model. However, small ...
Influence of Cryogenic Treatment on Wear Resistance and Microstructure of AISI A8 Tool Steel
The effects of deep cryogenic treatment (DCT) on the wear behavior of different tool steels have been widely reported in the scientific literature with uneven results. Some tool steels show a significant improvement in ...
Contributions of Bottom-Up Energy Transitions in Germany: A Case Study Analysis
Within the context of an energy transition towards achieving a renewable low-impact energy consumption system, this study analyses how bottom-up initiatives can contribute to state driven top-down efforts to achieve the ...
Iridescent Cellulose Nanocrystal Films: the Link Between Structural Colour and Bragg's Law
(Iop Publishing, 2018-04-30)
Structural colour is a phenomenon found in nature, which provides plants and animals with vibrant optical properties. The production of this colour is based on the interaction of incident light with the hierarchical ...
Lignocellulosic Biomass as a Source of Raw Materials for the Synthesis of Polyurethanes
Precursors have been satisfactorily synthesized from lignocellulosic biomass for later use in the synthesis of polyurethanes resulting in competitive final properties with those of petroleum derived polyurethanes
Accuracy Evaluation of Dense Matching Techniques for Casting Part Dimensional Verification
Product optimization for casting and post-casting manufacturing processes is becoming compulsory to compete in the current global manufacturing scenario. Casting design, simulation and verification tools are becoming crucial ...
Catalyst Deactivation And Regeneration Processes In Biogas Tri-Reforming Process. The Effect Of Hydrogen Sulfide Addition
(MDPI AG, 2018-01-09)
This work studies Ni-based catalyst deactivation and regeneration processes in the presence of H2S under a biogas tri-reforming process for hydrogen production, which is an energy vector of great interest. 25 ppm of hydrogen ...
The Shannon Entropy Trend of a Fish System Estimated by a Machine Vision Approach Seems to Reflect the Molar Se:Hg Ratio of Its Feed
The present study investigates the suitability of a machine vision-based method to detect deviations in the Shannon entropy (SE) of a European seabass (Dicentrarchus labrax) biological system fed with different selenium: ...
Reducing the Number of Individuals to Monitor Shoaling Fish Systems - Application of the Shannon Entropy to Construct a Biological Warning System Model
(Frontiers Media SA, 2018-05-08)
The present study aims at identifying the lowest number of fish (European seabass) that could be used for monitoring and/or experimental purposes in small-scale fish facilities by quantifying the effect that the number of ...
Towards Circular Economy: Different Strategies for Polyurethane Waste Recycling and the Obtaining of New Products
As a consequence of the high production and simultaneous consumption of polyurethanes (PU) a great volume of PU waste is landfilled. In this scenario, suitable and efficient routes for PU waste recycling have been searched ...
