Low-lying proton-emitting states of 16F have been investigated through the sequential particle decay reactions 14N(3He, n)16F(p)15O. Excitation energies were determined by measuring outgoing proton energies. Estimations of proton decay widths and spin limitations were made from proton spectra and angular correlation data which were obtained by detecting the protons in time coincidence with the associated neutrons at θn = 0°. To date, the ground-state spin of 16F has been considered to be J = 0; however, the present work suggests J = 1 to be preferable. 相似文献
Despite the fragility of TiO(2) under electron irradiation, the intrinsic structure of Au/TiO(2) catalysts can be observed by environmental transmission electron microscopy. Under reaction conditions (CO/air 100?Pa), the major {111} and {100} facets of the gold nanoparticles are exposed and the particles display a polygonal interface with the TiO(2) support bounded by sharp edges parallel to the 〈110〉 directions. 相似文献
Supramolecular materials based on host–guest interactions should exhibit high selectivity and external stimuli‐responsiveness. Among various stimuli, redox and photo stimuli are useful for its wide application. An external stimuli‐responsive adhesive system between CD host‐gels (CD gels) and guest molecules modified glass substrates (guest Sub) is focused. Here, the selective adhesion between host gels and guest substrates where adhesion depends on molecular complementarity is reported. Initially, it is thought that adhesion of a gel material onto a hard material might be difficult unless many guest molecules modified linear polymers immobilize on the surface of hard materials. However, reversible adhesion of the CD gels is observed by dissociating and re‐forming inclusion complex in response to redox and photo stimuli.
