Introduction: One of the most debated subjects in meteoritics is the time scale of events that occurred during the early history of the solar system. Chronometers based on short lived nuclides, such as Al, Mn, Fe, Pd, I, Sm, were extensively studied during the last decades. Some of them were shown to afford chronological resolutions on the order of a few Ma to less than one Ma [e.g. 1,2]. This ...

This paper describes research and development efforts in the application of nanoscale sensors to implement an original method for bed-of-needles testing for printed circuit boards testing. This approach performs functional testing that eliminates the need to have a pre-existing model of a circuit board while automating much of the development process. The general concept involves creating array...

Development of multifunctional nanoscale sensors working under physiological conditions enables monitoring of intracellular processes that are important for various biological and medical applications.
