Dual peptide functionalization of Zn alloys to enhance endothelialization for cardiovascular applications
(Elsevier, 2024-02-01)
Article
Accés obert
Realitzat a/amb: Institut de Bioenginyeria de CatalunyaA new generation of fully bioresorbable metallic Zn-based alloys could be used for stenting applications; however, the initial surface degradation delays stent re-endothelialization. Thus, this work proposes a dual strategy ... -
Polyelectrolyte multilayers modification of nanofiltration membranes to improve selective separation of mono- and multivalent cations in seawater brine
(Elsevier, 2024-02-05)
Article
Accés obertNowadays, brine produced in the Reverse Osmosis (RO) seawater desalination plants is a significant and largely untapped source of critical minerals and metals, which is usually discharged into the seas as wastewater. As a ... -
X-ray photoelectron spectroscopy (XPS) study of surface oxidation of UO2 doped with Gd2O3 at different temperatures and atmospheres
(2023-08)
Article
Accés obertIn this work, the influence of GdIII doping on the surface oxidation of UO2 has been investigated in situ by XPS. The samples were put in contact with either hydrogen, argon or synthetic air streams saturated with water ... -
Techno-economic analysis of seawater reverse osmosis brines treatment using nanofiltration modelling tools
(Elsevier, 2023-09)
Article
Accés obertThe management of seawater desalination (SWD) brine presents environmental and economic challenges. However, according to the circular economy approach, this residue offers an interesting source of resources. While ... -
Environmental and economic evaluation of implementing membrane technologies and struvite crystallisation to recover nutrients from anaerobic digestion supernatant
(Elsevier, 2023-09-01)
Article
Accés restringit per política de l'editorialThe present study investigates the environmental and economic feasibility of implementing membrane technologies and struvite crystallisation (SC) for nutrient recovery from the anaerobic digestion supernatant. To this end, ... -
Evaluation of the nanofiltration of brines from seawater desalination plants as pre-treatment in a multimineral brine extraction process
(2023-10)
Article
Accés obertMany materials essential to the European Union's (EU) economy lack primary resources, and the major suppliers of these materials are non-EU nations. It has been determined that seawater reverse osmosis (SWRO) desalination ... -
Metal-organic-framework-based nanofiltration membranes for selective multi-cationic recovery from seawater and brines
(Elsevier, 2023-11-05)
Article
Accés obertNanofiltration (NF) is gaining a role of increasing importance in Zero Liquid Discharge (ZLD)/Minimal Liquid Discharge (MLD) systems, enhancing the efficiency of downstream technologies to recover valuable minerals from ... -
Combination of polymer-stabilized nano zero-valent iron and biostimulated denitrifying bacteria for the removal of nitrate from groundwater
(Elsevier, 2023-11-01)
Article
Accés obertPolymer-stabilization of nano zero-valent iron (nZVI) is becoming a matter of research, although its effect on the reactivity towards targeted contaminants is not clear yet. Concurrently, combination of Abiotic Chemical ... -
The effects of iCVD film thickness and conformality on the permeability and wetting of MD membranes
(Elsevier, 2017-02)
Article
Accés obertMembranes possessing high permeability to water vapor and high liquid entry pressure (LEP) are necessary for efficient membrane distillation (MD) desalination. A common technique to prepare specialized MD membranes consists ... -
A mathematical model for ammonium removal and recovery from real municipal wastewater using a natural zeolite
(Elsevier, 2023-10-01)
Article
Accés restringit per política de l'editorialA study was carried out to remove/recover ammonium (NH4+) from residual effluents in tertiary treatment by sorption/desorption processes onto a natural clinoptilolite zeolite (NZ) in batch and fixed-bed column systems. ... -
Ammonium recovery and concentration from synthetic wastewater using a poly(4-methyl-1-pentene) (PMP) liquid–liquid membrane contactor: Flux performance and mass transport characterization
(Elsevier, 2023-12-01)
Article
Accés restringit per política de l'editorialHollow fiber membrane contactors are a promising technology for the removal and recovery of ammonia from liquid effluents. However, a better understanding of the process engineering (e.g. mass transport of ammonia over ... -
