It is often assumed that ‘nano’ is merely a communication and marketing token. Our inquiry in a number of French laboratories in the field of artificial molecular machines resulted in a quite different picture: a number of researchers are concerned with the definition of nanotechnology. This paper starts from the attempts made by one of the leading figure in the field of molecular machines, Chr...
Structural health monitoring (SHM) is an emerging field in which smart materials interrogate structural components to predict failure, expedite needed repairs, and thus increase the useful life of those components. Piezoelectric wafer active sensors (PWAS) have been previously adhesively-bonded to structures and demonstrate the ability to detect and locate cracking, corrosion, and disbonding th...

Selenium (Se) is an essential element for the cell that has multiple applications in medicine and technology; microorganisms play an important role in Se transformations in the environment. Here we report the previously unidentified ability of the soil bacterium Pseudomonas putida KT2440 to synthesize nanoparticles of elemental selenium (nano-Se) from selenite. Our results show that P. putida i...
