Charting a safe course for autonomous robots through a highly uncertain environment

May 19, 2022 (Nanwerk News) An autonomous spacecraft exploring the far-flung regions of the universe descends through the atmosphere of a remote exoplanet. The vehicle, and the researchers who programmed it, don’t know much about this environment. With so much uncertainty, how can the spacecraft plot a trajectory that will keep it from being squashed … Read more

a bond between David and Goliath

May 19, 2022 (Nanwerk News) When single particles like atoms and ions bond, molecules emerge. Such bonds between to particles can arise if they have for example opposite electrical charges and hence attract each other. The molecule observed at the University of Stuttgart exhibits a special feature: It consists of a positive electrically charged ion … Read more

Light-controlled reactions at the nanoscale

May 19, 2022 (Nanwerk News) Controlling strong electromagnetic fields on nanoparticles is the key to triggering targeted molecular reactions on their surfaces. Such control over strong fields is achieved via laser light. Although laser-induced formation and breaking of molecular bonds on nanoparticle surfaces have been observed in the past, nanoscopic optical control of surface reactions … Read more

Accelerating the pace of machine learning

May 19, 2022 (Nanwerk News) Machine learning happens a lot like erosion. Data is hurled at a mathematical model like grains of sand skittering across a rocky landscape. Some of those grains simply sail along with little or no impact. But some of them make their mark: testing, hardening, and ultimately reshaping the landscape according … Read more

Unmatched Sensitivity Obtained in New AFM Configuration

Chip-like oversized probes in atomic force microscopy (AFM) perturb the tuning fork’s oscillations, resulting in poor sensing. Hence, restoring the oscillatory characteristics in the oversized chip-like probes is critical to regaining high sensitivity. In an article recently published in the journal Microsystems & Nanoengineeringthe authors demonstrated a new approach to using a “tip-on-chip” probe by … Read more

Using Proteomics to Understand the Risk of Marine Nanotoxicology

Marine organisms are continually exposed to various nanoparticles due to their high deposition into coastal marine environments. A new study has focused on analyzing the independent and combinational effect of different nanoparticles, ie, titanium oxide (TiO2), zinc oxide (ZnO) and C60 fullerene (FC60) on Manila clam Ruditapes philippinarum. This study is available as pre-proof in … Read more
