Integrated metabolomic and transcriptomic analyses revealed metabolite variations and regulatory networks in Presl from four growth years.

To understand the mechanism of the dynamic accumulation of active ingredients in Presl, metabolomic and transcriptomic analyses of 5~8 years old . were performed. A total of 72 phenylpropanoids, 146 flavonoids, and 130 terpenoids showed marked changes.

transcriptome assembly and metabolomic analysis of three tissue types in .

Objective: The barks, leaves, and branches of have been historically used as a traditional Chinese medicine, spice, and food preservative, in which phenylpropanoids are responsible compounds. However phenylpropanoid biosynthesis pathways are not clear in . We elucidated the pathways by descriptive analyses of differentially expressed genes related to phenylpropanoid biosynthesis as well as to identify various phenylpropanoid metabolites.

Synthesis of Porous Hierarchical InO Nanostructures with High Methane Sensing Property at Low Working Temperature.

Different hierarchical porous InO nanostructures were synthesized by regulating the hydrothermal time and combining it with a self-pore-forming method. The gas-sensing test results show that the response of the sensor based on InO obtained after hydrothermal reaction for 48 h is about 10.4 to 500 ppm methane.

Intelligent multicolor nano-sensor based on nontoxic dual fluoroprobe and MOFs for colorful consecutive detection of Hg and cysteine.

Ultrasensitive detection of Hg in aquatic ecosystems is of great significance due to its high toxicity and ubiquity in water. Herein, using a one-step in-situ synthesis method, blue fluorescent carbon dots (CDs), red fluorescent InP/ZnS quantum dots (InPQDs), and MOFs (ZIF-8) integrated multicolor nano-sensor CDs/InPQDs@ZIF-8 was constructed for consecutive visual detection of Hg and Cys. The InPQDs can act as the response unit for Hg and Cys, with the limit of detection (LOD) of 8.

Superprotonic Conductivity of UiO-66 with Missing-Linker Defects in Aqua-Ammonia Vapor.

The design and preparation of proton-conducting metal-organic frameworks (MOFs) with superconductivity are of significance for the proton-exchange membrane fuel cell (PEMFC). Introducing functional structural defects to enhance proton conductivity is a good approach. Here, we synthesized a series of UiO-66 (first synthesized in the University of Oslo) with missing-linker defects and investigated the effect of defect numbers on the proton conductivity of the samples.

Dual-Functional Proton-Conducting and pH-Sensing Polymer Membrane Benefiting from a Eu-MOF.

Porous metal-organic frameworks (MOFs) have demonstrated a great potential in proton conduction and luminescence sensing due to functionalized nodes, ligands and channels, or pores. Herein, we prepared a hydrothermally stable Eu-MOF that also resisted acid and base using a bifunctional organic ligand containing carboxylic acid groups, which are easily coordinated to Eu ions, and Eu-phobic tetrazolyl groups as potential proton-hopping sites. The hydrogen bond network, which was constructed by the uncoordinated anionic tetrazolium and the coordinated and free water molecules, endowed this Eu-MOF with the highest proton conductivity of 4.

Poly[[tetra-aqua-tris-(μ(3)-hexane-1,6-di-carboxyl-ato)diterbium(III)] 0.25-hydrate].

In the title terbium coordination polymer, {[Tb(2)(C(6)H(8)O(4))(3)(H(2)O)(4)]·0.25H(2)O}(n), the Tb(III) atom is nine-coordinated, forming a TbO(9) polyhedra. Furthermore, two symmetric TbO(9) polyhedra share their edges, forming Tb(2)O(16) dimers, which are linked by adipate bridges into a layered structure.
