Microwave-assisted extraction of cellulose nanocrystals from almond (Prunus amygdalus) shell waste
(Frontiers Media, 2023-01)
Almond (Prunus amygdalus) is one of the most common tree nuts on a worldwide basis. This nut is highly regarded in the food and cosmetic industries. However, for all these applications, almonds are used without their shell ...
Design of Round-Nozzle Inertial Impactors Review with Updated Design Parameters
(Taiwan Association for Aerosol Research, 2023-03)
Round-nozzle inertial impactors are widely used aerosol measuring instruments to characterize the mass and chemical composition of airborne aerosol particles as a function particle aerodynamic diameter. This article ...
Sustainable mold biomachining for the manufacturing of microfluidic devices
(Elsevier, 2023-04)
Biomachining has been investigated as a sustainable and effective alternative to conventional prototyping techniques for molding polymeric materials for their subsequent use as microfluidic devices. A novel and simple ...
Automatic feedback and assessment of team-coding assignments in a DevOps context
(Springer, 2023)
We describe an automated assessment process for team-coding assignments based on DevOps best practices. This system and methodology includes the definition of Team Performance Metrics measuring properties of the software ...
Enzymatic upgrading of nanochitin using an ancient lytic polysaccharide monooxygenase
(Springer Nature, 2022-08-15)
Numerous enzymes have the potential to upgrade biomass, converting it into high-tech materials for new applications. However, the features of natural enzymes often limit their use beyond chemical conversion of the substrate. ...
Integrated Environmental and Exergoeconomic Analysis of Biomass-Derived Maleic Anhydride
(Wiley, 2022-09)
Life cycle analysis and exergy analysis are applied to compare the production of maleic anhydride from different feedstock, both biomass- and petrochemical-derived raw materials, in order to evaluate the sustainability of ...
Evaluation of Valorisation Strategies to Improve Spent Coffee Grounds’ Nutritional Value as an Ingredient for Ruminants’ Diets
(MDPI, 2023-04-26)
Lignin in animal diets is a limiting factor due to its low digestibility. This study assessed the effects of thermal or mechanical pre-treatments and enzymatic hydrolysis on spent coffee grounds’ (SCG) nutritional value ...
Development of High Temperature Water Sorbents Based on Zeolites, Dolomite, Lanthanum Oxide and Coke
(MDPI, 2023-04-06)
Methanation is gaining attention as it produces green methane from CO2 and H2, through Power-to-Gas technology. This process could be improved by in situ water sorption. The main difficulty for this process intensification ...
Optimisation of lignin liquefaction with polyethylene glycol/ glycerol through response surface methodology modelling
(Elsevier, 2023-08)
In order to diminish the dependence on oil lignin, which is the most abundant biopolymer of phenolic origin on Earth and can be utilised in different industrial endeavours, such as, the production of polyurethanes. In this ...
Sustainable Collagen Blends with Different Ionic Liquids for Resistive Touch Sensing Applications
(American Chemical Society, 2023-04)
Considering the sustainable development goals to reduce environmental impact, sustainable sensors based on natural polymers are a priority as the large im plementation of these materials is required considering the Internet ...
