Juniperus pseudosabina extract-mediated green synthesis of zinc oxide artichoke...
Kurbanova, Zulfira; Pereira, Sofia I. A.; Sousa, Ana S. S.; Piccirillo, Clara; Shaislamov, Ulugbek; Yubuta, Kunio; Teshima, Katsuya; Eitinger, ThomasThe green synthesis of zinc oxide (ZnO) using plant extracts provides an environmentally friendly alternative to conventional chemical and physical methods. This study investigates the green synthesis of ZnO using Juniperus pseudosabina (J. plseudosabina) extract, eliminating the need for thermal treatment and pH adjustment with alkali metal hydroxides. ZnO nanoparticles are synthesized by varying the plant ext...
Exploring the potential of a waste-derived bone char for pharmaceuticals adsorp...
Miranda, Catarina; Scalera, Francesca; Piancastelli, Andreana; Pullar, Robert C.; Tiritan, Maria Elizabeth; Piccirillo, Clara; Castro, Paula M. L.In this study, the effect of salinity in wastewater on the adsorption capacity of a bone char material prepared through pyrolysis of tuna bones at 1000 °C was investigated for two pharmaceuticals, tramadol (TRA) and venlafaxine (VNF), both contaminants of emerging concern. This is the first time that the adsorption efficiency of a bone char-type material was tested in such conditions. The Tuna Bone Char (TBC) w...
The potential of tuna bone char as a sorbent material for pharmaceuticals remov...
Miranda, Catarina; Piccirillo, Clara; Tiritan, Maria Elizabeth; Castro, Paula M. L.; Amorim, Catarina L.The extensive consumption of pharmaceuticals combined with the limited removal capacity of wastewater treatment processes result in their continuous accumulation in water bodies which can adversely affect the environment and human health. Thus, efficient strategies to avoid the release of these persistent compounds in the environment are needed. The adsorption-based processes are promising methodologies to redu...
Valorisation of tuna bone waste through its application for the removal of pers...
Piccirillo, Clara; Miranda, Catarina; Scalera, Francesca; Piancastelli, Andreana; Tiritan, Maria Elizabeth; Castro, Paula M. L.; Amorim, Catarina L.The access to safe and clean water is a critical issue faced by our society. One of the major problems is the presence of contaminants of emerging concern (CECs) in water bodies. CECs include pollutants with poor removal rates in wastewater treatment plants, causing adverse effects on ecosystems and humans. Within CECs, pharmaceuticals received increasing attention due to their continuous release into aquatic e...

Piccirillo, Clara; Miranda, Catarina; Scalera, Francesca; Piancastelli, Andreana; Tiritan, Maria Elizabeth; Amorim, Catarina L.; Castro, Paula M. L.Introduction: Today one of the main problems affecting our environment is the presence of Contaminants of Emerging Concern (CECs) in surface waters. CECs are stable compounds that are not degraded by traditional wastewater treatments processes, accumulating in the environment and potentially causing harm. Within CECs, pharmaceuticals are of particular concern, due to their increased consumption, with the new EU...

Exploring the fate of chiral pharmaceuticals in an AGS system under saltwater i...
Miranda, Catarina; Amorim, Catarina; Piccirillo, Clara; Tiritan, Maria Elizabeth; Castro, PaulaAerobic granular sludge (AGS) is a robust technology, largely adopted in wastewater treatment plants (WWTPs) worldwide. However, there is a lack of knowledge regarding how this technology deals with saltwater intrusion and variable daily wastewater salinity loads. With the sea level rise, in coastline WWTPs, seawater infiltration into sewers is a growing problem. In addition, the increase in pharmaceutical prod...
Development of energy-saving innovative hydraulic mortars reusing spent coffee ...
Saeli, Manfredi; Capela, Marinélia N.; Piccirillo, Clara; Tobaldi, David M.; Seabra, M. Paula; Scalera, Francesca; Striani, RaffaellaThis paper reports the development of green bio-composite mortars, obtained reusing spent coffee ground (SCG), an agri-food residue, in the light of the Circular Economy approach. This process can boost the sustainability in Construction and proposes an alternative to SCG disposal in landfill, potentially dangerous to humans and the environment. For the first time, specimens were produced and compared using dif...
Poly(l-lactide-co-caprolactone-co-glycolide)-based nanoparticles as delivery pl...
Rebanda, Magda M.; Bettini, Simona; Blasi, Laura; Gaballo, Antonio; Ragusa, Andrea; Quarta, Alessandra; Piccirillo, ClaraPolymeric nanoparticles made of the copolymer Poly(L-lactide-co-caprolactone-co-glycolide) were prepared using the solvent evaporation method. Two different surfactants, polyvinyl alcohol and dextran, and a mixture of the two were employed. The three types of nanoparticles were used as hosting carriers of two chemotherapeutic drugs, the hydrophilic doxorubicin and the hydrophobic SN-38. The morphostructural cha...
Hydroxyapatite-chitosan 3D scaffolds made from natural and sustainable sources
Scalera, Francesca; Pereira, Sofia; Bucciarelli, Alessio; Tobaldi, David; Quarta, Alessandra; Gervaso, Francesca; Castro, Paula; Polini, AlessandroThe use of natural and sustainable sources in the chemical processes is becoming an issue of increasing importance; in addition to this, often natural materials have features (i.e. structure or morphology) which could lead to enhanced performances. Within this frame, in this work we report about the preparation of hydroxyapatite‐chitosan 3D scaffolds made from natural and sustainable sources.Hydroxyapatite (HA)...
