Thermally robust and chemically inert Ag@SiO2 nanoprobes are employed to provide the surface enhanced Raman scattering (SERS) effect for an in situ/operando study of the early stage of carbon deposition on nickel-based solid oxide fuel cell (SOFC) anodes. The enhanced sensitivity to carbon enables the detection of different stages of coking, offering insights into intrinsic coking tolerance of ...

The ecological footprint model was used in this paper to evaluate the sustainable development status of Baotou City by calculating footprint, carrying capacity and deficit/surplus 2018. results showed that: (1) In 2018, per capita 1.11506 ha, 0.8371 ha. There is 0.2780 ha deficit, which a fragile unsustainable state; (2) demand for farmland, grassland fossil energy land large, but limited; (3) ...

The graft copolymer of locust bean gum (LBG) and acrylamide has been synthesized by microwave assisted method using potassium persulphate (KPS) as an initiator in aqueous medium. Different reaction parameters such as time, initiator concentration, monomer concentration, polymer concentration, and microwave power were studied to get maximum graft copolymer. The grafted copolymer was characterize...

Optimizing coal blending is important for high-quality development of coking industries, among which deep understanding relationships between characteristics and coke quality critical. This work selected four typical coals from Shanxi Province in China to investigate influences their structures properties on quality. Although these samples belong coals, the mechanical strength thermal correspon...

The Xishan coalfield is an important coking coal-producing area in China. No. 8 and 9 coals of the Taiyuan formation were sampled tested from nine mines center north coalfield, coal’s quality characteristics, element occurrence enrichment sedimentary environment characteristics analyzed to provide a foundation for clean efficient coal utilization identification associated resources. results obt...
