Xenon Trapping
Xenon (Xe) atoms are trapped in silicate nanocages in contact with a metal surface. The atoms can be trapped at moderate temperatures (> 300 K) and released by heating to elevated temperatures (> 750 K). This can benefit several applications, including Xe production, nuclear power, nuclear waste remediation, and nonpro liferation of nuclear weapons. More details can be found in...
Xenon (Xe) is a valuable and scarce noble gas used in various applications, including lighting, electronics, and anesthetics, among many others. It is also a volatile byproduct of the nuclear fission of uranium. A novel material architecture consisting of silicate nanocages in contact with a metal surface and an approach for trapping single Xe atoms in these cages is presented. The trapping is done...
A challenge in the synthesis of single‐wall carbon nanotubes (SWCNTs) is the lack of control over the formation and evolution of catalyst nanoparticles and the lack of control over their size or chirality. Here, zeolite MFI nanosheets (MFI‐Ns) are used to keep cobalt (Co) nanoparticles stable during prolonged annealing conditions. Environmental transmission electron microscopy (ETEM) shows that the...
