Dense Packing of Acetylene in a Stable and Low-Cost Metal-Organic Framework for Efficient C H /CO Separation.

Porous materials for C H /CO separation mostly suffer from high regeneration energy, poor stability, or high cost that largely dampen their industrial implementation. A desired adsorbent should have an optimal balance between excellent separation performance, high stability, and low cost. We herein report a stable, low-cost, and easily scaled-up aluminum MOF (CAU-10-H) for highly efficient C H /CO separation.

[Study on identification of Astragali Radix and Hedysari Radix by PCR amplification of specific alleles].

To explore the new method of discriminating Astragali Radix and Hedysari Radix by using PCR amplification of specific alleles, 30 samples of the different Astragali Radix materials and 28 samples of Hedysari Radix were collected. The total DNA of all samples were extracted, trnL-trnF sequence from Astragali Radix and Hedysari Radix was amplified by PCR and sequenced unidirectionally. These sequences were aligned by using Clustul W.

Molecular systematics of Genus Atractylodes (Compositae, Cardueae): evidence from Internal Transcribed Spacer (ITS) and trnL-F sequences.

To determine the evolutionary relationships among all members of the genus Atractylodes (Compositae, Cardueae), we conducted molecular phylogenetic analyses of one nuclear DNA (nrDNA) region (internal transcribed spacer, ITS) and one chloroplast DNA (cpDNA) region (intergenic spacer region of trnL-F). In ITS and ITS + trnL-F trees, all members of Atractylodes form a monophyletic clade. Atractylodes is a sister group of the Carlina and Atractylis branch.
