Organic crystals, such as phthalocyanine nanocrystal, were successfully hybridized with Pt nanoparticles using a nanohybridization technique. The presence of highly dispersed Pt nanoparticles on the surface of phthalocyanine was confirmed by the combination of transmission electron microscopy and three-dimensional electron tomography. Catalytic activities of hybridized samples with different degrees of dispersions were also examined as oxygen reduction reactivity (ORR) with a linear potential sweep method. It was found that oxygen reduction activity increased with increasing Pt dispersion, and reasonably high ORR was observed on Pt-dispersed phthalocyanine nanocrystal even at 2 wt% Pt loading.

A new windowless X-ray energy-dispersive spectroscopy (XEDS) detector has been developed for an analytical electron microscope (AEM). Different from the conventional XEDS detectors, the new detector does not contain an ultra-thin window (UTW) and a vacuum gate valve which are the major causes of low X-ray detection sensitivity and vibration problems for AEM imaging, respectively. The performance of the newly designed detector was examined at an AEM column vacuum level of 105 Pa. The X-ray detectability was improved considerably; in particular, the sensitivity for detecting nitrogen characteristic X-ray signal was three times higher than that of the conventional UTW detectors.
