Feasibility of Vermicomposting of Spent Coffee Grounds and Silverskin from Coffee Industries: A Laboratory Study
(MDPI, 2020-08-03)
In the coffee industry, several by-products are generated during the production and consumption of coffee and represent an important waste from an environmental viewpoint. For improving the knowledge about this issue, a ...
Valorization of Insulation Cellulose Waste as Solid Biomass Fuel
(MDPI, 2021-09-04)
This paper investigates the ability of insulation cellulose fiber powder (CFP) to be pelletized for its valorization as biomass fuel. CFP is a waste originating from insulation cellulose manufacturing that lacks any method ...
Stabilization of a Clay Soil Using Cementing Material from Spent Refractories and Ground-Granulated Blast Furnace Slag
(MDPI, 2021-03-10)
Nowadays, huge amounts of refractory materials are generated around the world. The majority of them lack valorization methods. This study analyzes the ability of a doloma and two magnesia spent refractory wastes as soil ...

The Influence of Copolymer Composition on PLGA/nHA Scaffolds’ Cytotoxicity and In Vitro Degradation
(MDPI, 2017-07-06)
The influence of copolymer composition on Poly(Lactide-co-Glycolide)/nanohydroxyapatite (PLGA/nHA) composite scaffolds is studied in the context of bone tissue engineering and regenerative medicine. The composite scaffolds ...
Mechanical Properties of Three Bamboo Species: Effect of External Climatic Conditions and Fungal Infestation in Laboratory Conditions
(MDPI, 2022-12-07)
Bamboo is a material with good tensile and flexural resistance. As a construction material with structural capacity, using bamboo implies considerable environmental advantages in relation to other typical materials such ...
Vermicomposting of Lavender Waste: A Biological Laboratory Investigation
(MDPI, 2022-11-25)
In the present work, lavender waste, a residue of the essential oil extract industry, was used to feed Eisenia andrei with mature horse manure at ratios of 0:100, 25:75, 50:50, 75:25 and 100:0 on dry weight basis. ...
Effect of powder particle size distribution on the surface finish of components manufactured by laser powder bed fusion
(Springer, 2023)
One of the key aspects of the laser powder bed fusion (L-PBF) process is the quality of the raw powder since it affects the final properties of the manufactured parts. In this study, 13 batches of Inconel (R) 718 powder ...
Thermal endurance of xylitol as a phase change material for thermal energy storage applications
(Elsevier, 2022-11)
Xylitol shares the good thermophysical properties of other sugar alcohols that are candidates for thermal storage purposes, with one singularity: it shows noticeable supercooling coupled with a low crystallization rate. ...
A comprehensive study of the phase segregation of a urea-based phase change material tested under thermal cycling conditions
(Elsevier, 2023-04)
Eutectic mixtures are used as PCMs due to the possibility to tailor the melting temperatures and mainly because the phase transition occurs at a unique temperature. Eutectic mixtures are assumed to be congruent melting and ...
