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
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
May 19, 2022 (Nanwerk News) Billions of years ago, a series of volcanic eruptions broke loose on the moon, blanketing hundreds of thousands of square miles of the orb’s surface in hot lava. Over the eons, that lava created the dark blotches, or maria, that give the face of the moon its familiar appearance today. … Read more
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
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
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

In a study published in the journal Electrochimica Acta, a scalable and cost-effective technique for generating three-dimensional, structural, highly efficient lithium (Li) metal anodes is suggested, opening up new avenues for studies into Li metal and potentially other metal anodes . Study: In-situ growth of iron nanoparticles on porous carbon nanofibers for structural high-performance … Read more
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
A team of researchers recently published a paper in the journal ACS Applied Nano Materials that demonstrated the feasibility of using novel lead-free perovskite nanocrystals for optoelectronic applications. Study: Lead-free Rb2SnCl6:Bi Perovskite Nanocrystals for Luminescence Emission.
