Abstract Solution-processed and low-temperature Sn-rich perovskites show their low bandgap of about 1.2 eV, ... Consequently, the methylammonium-rubidium Sn-Pb perovskite photodetectors simultaneously achieve larger photocurrent and lower noise current. Finally, highly efficient UV–vis–NIR (300–1100 nm) photodetectors with record …
Nitric oxide (NO) causes autism, blocking NO reverses autism. Autism rates are relentlessly climbing. Even the official stats, which are manipulated in order to avoid disclosing the scale of the catastrophe, are shocking - i.e. about one in thirty children have autism and the increase in that rate shows no signs of abating.

Background: The most reliable quantitative variable on Rubidium-82 (82 Rb) cardiac PET/CT for predicting major adverse cardiovascular events (MACE) has not been characterized with low-dose silicon photomultipliers (SiPM) technology, which allows halving injected activity and radiation dose delivering less than 1.0 mSv in a 70-kg …
Cationic ions (rubidium or cesium) could be added to battery electrolytes at low concentrations to control the formation of lithium dendrites. These cations stacked on the protrusion growth result in an electrostatic barrier ( Fig. 4 (a) ). The Li-ions still deposit until a smooth layer is formed ( Fig. 4 (b)) and, finally, self-healing is ...
Abstract: we report on the progress towards a miniaturized rubidium timing source based on double resonance (DR) in 85Rb.
