Pollen micromorphology of eastern Chinese Polygonatum and its role in taxonomy by using scanning electron microscopy

Microscopy research and technique (Print), 2021
Although considerable progress has recently been made in the taxonomic study of Asparagaceae, but the Polygonatum remains one of the most poorly investigated genus.

Polysaccharide based "lotus seedpod surface-like" porous microsphere with precise and controllable micromorphology for ultrarapid hemostasis.

ACS Applied Materials and Interfaces, 2019
Rapid water absorption rate has become a bottleneck, which limit urtalrapid hemostatic performance of hemostatic microspheres. Herein, we reported a "lotus seedpod surface-like" polysaccharide hemostatic microsphere (PHMs) with "macro-pits on surface ...

The micromorphology of loess‐paleosol sequences in central Alaska: A new perspective on soil formation and landscape evolution since the Late Glacial period (c. 16,000 cal yr BP to present)

Geoarchaeology, 2020
The middle Tanana Valley of central Alaska contains a well‐preserved record of human occupation and paleoenvironmental change since the Late Glacial period (c. 16,000 cal yr BP) and is a critical region for understanding human dispersal into the Americas.

Effect of Micromorphology on Alkaline Polymer Electrolyte Stability.

ACS Applied Materials and Interfaces, 2018
Recent studies demonstrated that the chemical stability of alkaline polymer electrolytes (APEs) could be improved by reducing the inductive effect between cations and backbones. Therefore, pendent cations were recommended.
