A Hydrolytically Stable Metal-Organic Framework for Simultaneous Desulfurization and Dehydration of Wet Flue Gas.

Metal-organic frameworks (MOFs) have great prospects as adsorbents for industrial gas purification, but often suffer from issues of water stability and competitive water adsorption. Herein, we present a hydrolytically stable MOF that could selectively capture and recover trace SO from flue gas, and exhibits remarkable recyclability in the breakthrough experiments under wet flue-gas conditions, due to its excellent resistance to the corrosion of SO and the water-derived capillary forces. More strikingly, its SO capture efficiency is barely influenced by the increasing humidity, even if the pore filling with water is reached.

Facile Tuned TSCT-TADF in Donor-Acceptor MOF for Highly Adjustable Photonic Modules based on Heterostructures Crystals.

Highly adjustable photonic modules were constructed based on the heterostructures crystals of a new series of donor-acceptor metal-organic framework (D-A MOF) featuring highly tunable thermally activated delayed fluorescence (TADF). By introducing N-phenylcarbazole and derivatives as donor guests into the acceptor host NKU-111, highly tunable through-space charge transfer based TADF could be achieved through the engineering of heavy atom effect, which result in modulatable emission wavelength (540 to 600 nm) and enhanced quantum yield (up to 30.86 %).

Tuning the Trade-Off between Ethane/Ethylene Selectivity and Adsorption Capacity within Isoreticular Microporous Metal-Organic Frameworks by Linker Fine-Fluorination.

The pore dimension and surface property directly dictate the transport of guests, endowing diverse gas selective adsorptions to porous materials. It is highly relevant to construct metal-organic frameworks (MOFs) with designable functional groups that can achieve feasible pore regulation to improve their separation performances. However, the role of functionalization in different positions or degrees within framework on the separation of light hydrocarbon has rarely been emphasized.

In order to provide rationale for selection of good germplasm in Rubus chingii, main effective medicinal ingredients of green fruit such as gallic acid, ellagic acid, kaempferol-3-rutinoside, astragalin and tiliroside were measured using UPLC for the samples collected from Chun'an county of Zhejiang province, and such parameters as soluble solid contents of ripe fruit of some samples were also measured to study variation among individuals and correlation.

[Spatial-temporal and environmental effects of catch rate on Antarctic krill fishery in the South Georgia Island in the austral winter season based on the fine scale data].
