This book contains ten extended abstracts submitted by PhD students of the Doctoral Program in Water Science and Technology within the framework of our annual meeting. The meeting was addressed to undergraduates, master and doctoral students interested in the ongoing research, current and future applications in the field of water science and technology. With this purpose, doctoral students were asked to summarize their ongoing activities in the format of an outreach scientific paper, with scientific rigor, but attractive, highlighting its innovative and most relevant aspects and potential applications.
