Approach for natural gas to be a primary energy source in China

Weihe HUANG, Jindian CHEN, Chuan FU, Yan HUANG

Frontiers of Engineering Management 2019, Volume 6, Issue 4,   Pages 467-476 doi: 10.1007/s42524-019-0068-6

Abstract: This work reveals the positioning of natural gas in the evolution of world energy and the general law of its development. In the long-term adjustment of energy structure, natural gas has gradually become the primary energy source because of five factors: policy, resources, technology, facilities, and market. To expedite the revolution of energy production and consumption, China must urgently expand the use of natural gas toward a more positive role in complementing coal and renewable energy and prioritize its usage in three areas, namely, urban gas, power generation, and industrial fuel. Natural gas is expected to account for approximately 15% of China’s total energy consumption in the future. For natural gas to be the primary energy, the exploitation of gas resources must be expanded, resource access must be improved, a flexible trade system must be set up, infrastructure investment must be increased, and the security system must be enhanced.

Frontiers of Chemical Science and Engineering 2021, Volume 15, Issue 1,   Pages 156-163 doi: 10.1007/s11705-020-1986-x

Abstract: Unique self-assembled iron(II) molybdenum(IV) oxide (Fe Mo O ) mesoporous hollow spheres have been facilely constructed the bubble-template-assisted hydrothermal synthesis method combined with simple calcination. The compact assembly of small nanoparticles on the surface of the hollow spheres not only provides more active sites for the Fe Mo O , but also benefits the stability of the hollow structure, and thus improved the lithium storage properties of Fe Mo O . The Fe Mo O mesoporous hollow spheres exhibit high initial discharge and charge capacities of 1189 and 997 mA∙h∙g respectively, as well as good long-term cycling stability (866 mA∙h∙g over 70 cycles) when used as a lithium-ion battery anode. This feasible material synthesis strategy will inspire the variation of structural design in other ternary metal molybdates.

Approaching the binding between Cu(II) and aerobic granules by a modified titration and µ-XRF

Hongwei LUO,Longfei WANG,Zhonghua TONG,Hanqing YU,Guoping SHENG

Frontiers of Environmental Science & Engineering 2016, Volume 10, Issue 2,   Pages 362-367 doi: 10.1007/s11783-015-0803-0

Abstract: Interactions between metals and activated sludge can substantially affect the fate and transport of heavy metals in wastewater treatment plants. Therefore, it is important to develop a simple, fast and efficient method to elucidate the interaction. In this study, a modified titration method with a dynamic mode was developed to investigate the binding of Cu(II), a typical heavy metal, onto aerobic granules. The titration results indicated that pH and ionic strength both had a positive effect on the biosorption capacity of the granular sludge. The -XRF results demonstrated that the distribution of metals on the granular surface was heterogeneous, and Cu showed strong correlations and had the same “hot spots” positions with other metal ions (e.g., Ca, Mg, Fe etc.). Ion exchange and complexing were the main mechanisms for the biosorption of Cu(II) by aerobic granules. These results would be beneficial for better understanding of Cu(II) migration and its fate in wastewater treatment plants.
