In the field of water treatment, it is of importance to fabricate an adsorbent with large adsorption capacity and high reproducibility for efficiently removing heavy metal ions Pb (II) from polluted water. In this work, a novel Ti-based MOFs material (BDB-MIL-125(Ti)@Fe 3 O 4 ) was designed and...

The effects of the site symmetric distortion induced by the phase transition on up-conversion emission and thermal sensing performance of Gd 2 (MoO 4 ) 3 :Yb 3+ /Er 3+ (GMO) crystals are elaborately studied by minimizing interference from many factors. Monoclinic GMO shows much stronger...

Chemical Looping Dry Reforming (CLDR) using oxygen carrier (OC) is a novel technology to convert CO 2 to CO. Currently, Ca 2 Fe 2 O 5 (CF) OC is found to be a potential material for CLDR. In this paper, Zr 0.5 Ce 0.5 O 2 (ZC) was used to improve the reduction rate of CF OC and alleviate the...

The solidification characteristics of C700R-1 alloy was investigated by DSC analysis, in-situ observation, quenching experiment and Thermo-Calc calculation. The segregation behavior during solidification was analyzed by Scanning Electron Microscope and Electron Probe Microanalysis. At the...

We find a strong and robust credit penalty effect on heavily-polluting firms of the 2012 'Green Credit Guidelines' (GCG) of China. Heavily polluting firms' access to both short-term and long-term bank credit reduces dramatically. We also find some evidence of a credit rewarding effect —...

A combined heat and power plant with regenerative closed-cycle gas turbine is considered. The heat transfer losses, irreversible adiabatic losses and irreversible pressure drop losses are considered in the plant. The expressions of dimensionless profit rate and exergy efficiency are gained. The...

Graphene (GR) was used as filler to improve the performance of fire resistance, thermal stability, smoke suppression of waterborne intumescent fire-retardant coating. The influence of graphene (GR) on the properties of the intumescent fire-retardant coating was studied by fire protection test,...

Traditional steam methane reforming facilities for producing hydrogen not only consume a large amount of natural gas, but also emit a lot of greenhouse gas. Considering the utilization of clean energy, the reduction of carbon dioxide emission, and the production of chemicals, this paper...

This paper presents evidence on the spatial distribution and effects of urban agglomeration on firm innovation. It uses a unique dataset that consistently defines city boundaries and identifies firms' innovation-related activities across 25 developing countries in Asia. We find firm innovation...
