متن کاملUltrafast bond softening in bismuth: mapping a solid's interatomic potential with X-rays.
Intense femtosecond laser excitation can produce transient states of matter that would otherwise be inaccessible to laboratory investigation. At high excitation densities, the interatomic forces that bind solids and determine many of their properties can be substantially altered. Here, we present the detailed mapping of the carrier density-dependent interatomic potential of bismuth approaching ...
متن کاملThe Impact of Low Level X-rays on Biosynthesis of Gold Nanoparticles by Actinobacteria
Background; Gold nanoparticles (GNPs) play an important role in medical, health and environmental applications. All kinds of microorganisms were found to be able to synthesize GNPs. The optimization of laboratory conditions for achieving more economical benefits of mass production has been studied widely. Methods;This study assesses the enhancing effect of low-level X-rays on the biosynthesis ...
