The hybrid composite PW11Co/PAMAM was characterized by FT-IR, UV-Vis diffuse reflectance spectra, XPS, XRD and TG/DTA, indicating that the PW11Co was chemically anchored to PAMAM. The morphologies of the title composite were characterized by scanning electron microscopy and transmission electron microscopy. The catalytic activity was evaluated by oxidation of isobutyraldehyde to isobutyric acid in MeCN under mild conditions (20 ℃, ambient pressure), showing that the title compound is a more effective and recoverable catalyst than corresponding PW11Co.

Based upon the ecoanatomical method, leaf anatomical characters of eleven populations of six evergreen species (Cyclobalanopsis glauca, C. myrsinaefolia, C. gracilis, Castanopsis sclerophylla, C. eyrei and Lithocarpus glaber) from the eastern subtropical area of China were analyzed and compared with SPSS, DCA and TWINSPAN. The results are: 1. Although the leaf structures of the eleven populations still belong to the mesophyll type, they all express the trend of xerophilization. 2. There are some differences in leaf anatomical characters among populations, species and genera, which occur as the results of their adaptation to different habitats. 3. Different leaf anatomical characters have different variations among populations, species and genera, of which leaf thickness and palisade tissue thickness (considered as ecological adaptation characters) have greater variation than sponge tissue thickness, lower cuticle thickness and lower epidermis thickness (as systematical evolution characters). 4. The leaves of C. sclerophylla and C. glauca with thicker lamina, palisade tissue and cuticle (a multilayered upper epidermis in C. sclerophylla) are thought to better adapt to their dry habitat. The leaves of C. eyrei with thicker sponge tissue, although characterized by a multlayered upper epidermis, adapt to their humid and warm habitat. The leaves of C. myrsinaefolia and C. gracilis characterized by a thinner lamina, a less palisade tissue and a moderate cuticle thickness adapt to the humid and cool habitat in a middle mountain.
