Amide-Functionalized In-MOF for Effective Hydrocarbon Separation and CO Catalytic Fixation.

Energy saving and emission reduction have always been the goal of separation and catalysis pursued in industrial production. Metal-organic frameworks (MOFs) are leading porous crystal materials with unique advantages in these fields. Based on an amide-modified ligand 5-(ethyl oxamate)-isophthalic acid (HEtL), a new porous indium-organic framework (MeNH)[InL]·2DMF·2HO () was synthesized and structurally characterized.

Acetylene Separation by a Ca-MOF Containing Accessible Sites of Open Metal Centers and Organic Groups.

Efficient separation of acetylene from a ternary acetylene-containing mixture is an important and vital task in petrochemical industry, which is difficult to achieve using a single material. Herein, a new Ca-based metal-organic framework (MOF) [Ca(dtztp)(DMA)]·2HO () was constructed using the ,-donor ligand 2,5-di(2-tetrazol-5-yl)terephthalic acid and the less-studied alkaline earth Ca ions. The MOF shows a 3D honeycomb framework based on unique metal-carboxylate-azolate rod secondary building units.

The effects of dust-haze on mortality are modified by seasons and individual characteristics in Guangzhou, China.

This study aimed to investigate the effects of dust-haze on mortality and to estimate the seasonal and individual-specific modification effects in Guangzhou, China. Mortality, air pollution and meteorological data were collected for 2006-2011. A dust-haze day was defined as daily visibility <10 km with relative humidity <90%.

[Water intake sources analysis of adults in four cities of China in summer].

Objective: To investigate the water intake sources of adults in the four cities of China in summer.

Methods: A total of 64 adults aged 18 - 60 yrs from the four cities (Beijing, Shanghai, Chengdu and Guangzhou) were selected using convenient sampling method. The information on amounts and types of daily drinking water was recorded by subjects for three consecutive days using a quantitative measurement.
