Life cycle assessment of grape cultivation in Piedmont, Italy

The main objective of this paper is to present a comprehensive life cycle assessment (LCA) of grape cultivation for wine, in Piedmont, Italy. A cradle to gate approach was followed for grape cultivation (functional unit: 1 kg of grapes), based on data collected for the Barbera and Moscato varieties. Life cycle environmental impacts were analysed for the following categories: fossil depletion (FD), global warmin...

A simple, efficient and selective process for recycling La (and Al) from fluid ...

Spent fluid cracking catalyst (FCC) is an abundant waste material derived from oil refining processes and notably characterized by its content in rare earth metals, such as cerium (Ce) and lanthanum (La). In this work, it was our main aim to develop a simple but effective flowsheet, based on a single acid assisted leaching step followed by two consecutive precipitation steps, for recovering La with high purity ...

Multifunctional gold-nanoparticles: A nanovectorization tool for the targeted d...

Due to their small size and unique properties, multifunctional nanoparticles arise as versatile delivery systems easily grafted with a vast array of functional moieties, such as anticancer cytotoxic chemotherapeutics and targeting agents. Here, we formulated a multifunctional gold-nanoparticle (AuNP) system composed of a monoclonal antibody against epidermal growth factor receptor (EGFR) (anti-EGFR D-11) for ac...
