Highly Efficient Nitrogen Reduction to Ammonia through the Cooperation of Plasma and Porous Metal-Organic Framework Reactors with Confined Water.

While the ambient N reduction to ammonia (NH) using HO as hydrogen source (2N+6HO=4NH+3O) is known as a promising alternative to the Haber-Bosch process, the high bond energy of N≡N bond leads to the extremely low NH yield. Herein, we report a highly efficient catalytic system for ammonia synthesis using the low-temperature dielectric barrier discharge plasma to activate inert N molecules into the excited nitrogen species, which can efficiently react with the confined and concentrated HO molecules in porous metal-organic framework (MOF) reactors with V, Cr, Mn, Fe, Co, Ni and Cu ions. Specially, the Fe-based catalyst MIL-100(Fe) causes a superhigh NH yield of 22.

Plasma-Driven Efficient Conversion of CO and HO into Pure Syngas with Controllable Wide H/CO Ratios over Metal-Organic Frameworks Featuring In Situ Evolved Ligand Defects.

While the mild production of syngas (a mixture of H and CO) from CO and HO is a promising alternative to the coal-based chemical engineering technologies, the inert nature of CO molecules, unfavorable splitting pathways of HO and unsatisfactory catalysts lead to the challenge in the difficult integration of high CO conversion efficiency with produced syngas with controllable H/CO ratios in a wide range. Herein, we report an efficient plasma-driven catalytic system for mild production of pure syngas over porous metal-organic framework (MOF) catalysts with rich confined HO molecules, where their syngas production capacity is regulated by the in situ evolved ligand defects and the plasma-activated intermediate species of CO molecules. Specially, the Cu-based catalyst system achieves 61.

Regulated Dual Defects of Bridging Organic and Terminal Inorganic Ligands in Iron-based Metal-Organic Framework Nodes for Efficient Photocatalytic Ammonia Synthesis.

Engineering advantageous defects to construct well-defined active sites in catalysts is promising but challenging to achieve efficient photocatalytic NH synthesis from N and HO due to the chemical inertness of N molecule. Here, we report defective Fe-based metal-organic framework (MOF) photocatalysts via a non-thermal plasma-assisted synthesis strategy, where their NH production capability is synergistically regulated by two types of defects, namely, bridging organic ligands and terminal inorganic ligands (OH and HO). Specially, the optimized MIL-100(Fe) catalysts, where there are only terminal inorganic ligand defects and coexistence of dual defects, exhibit the respective 1.

Orai1-mediated store-operated Ca entry promotes cervical cancer progression through IL-6 signaling.

Cervical cancer is a major cause of cancer-associated mortality among women in developing countries. Orai1-mediated store-operated Ca entry (SOCE) is the primary mechanism underlying most of the non-excitable calcium influx into cells. There is at present limited evidence showing that Orai1 can function as an oncogene or a tumor suppressor depending on the cancer type.

Structural elucidation of galactomannan from seeds of Crotalaria mucronata Desv. by atomic force microscopy.

A non-ionic water-soluble galactomannan, isolated from the seed endosperm of Crotalaria mucronata Desv., may be an ideal thickener to increase food viscosity. The present study hypothesized that the viscous property of Crotalaria galactomannan may be associated with its spatial structure.

Statistical optimization of culture medium for production of exopolysaccharide from endophytic fungus Bionectria ochroleuca and its antitumor effect in vitro.

Endophytic fungi have been recognized as possible useful sources of bioactive metabolites. However, exopolysaccharide (EPS) production from endophytic fungi and its antitumor activity have been less explored. In the present study, endophtic fungus Bionectria ochroleuca M21 was exploited for the production of EPS in submerged culture.

[Allelopathy of aqueous extract from Ligularia virgaurea, a dominant weed in psychro-grassland, on pasture plants].

Ligularia virgaurea is a noxious weed widely distributed in the alpine grassland of east Qinghai-Tibet Plateau of China. This paper studied the allelopathy of its aqueous extract on the pasture plants Festuca sinensis, Bromus magnus, Elymus nutans, Poa annua, and F. ovina in the region.
