This paper presents the development and experimentations of transparent vibrating piezoelectric micromembranes dedicated to protecting immersed measurement instruments from marine biofouling. As any surface immersed is subject to the adhesion and settlement of organisms, especially in seawater, transparent materials quickly become opaque, resulting...

Quantification of trace levels of metal ions is an important issue in terms of health and environment safety. Ion-imprinted polymers (IIPs) are synthetic materials that present excellent selectivity properties. Therefore, when combined with electrochemical sensors, proven to be low-cost and time-efficient, they can act as remarkably selective recep...

Marine biofouling is the unwanted accumulation of biological origin matters on submerged surfaces. Biofouling is a major economic burden on navy and commercial ships, as well as civil structures, piping systems, sensors, and power generating facilities. Due to the vast variety of marine organisms that colonize submerged surfaces, no surface has bee...
