    1. Thermodynamic optimization of a neoteric geothermal poly-generation system in an oilfield (pages 1939–1951)

      The cold source evidently increase the net power output of the organic Rankine cycle, but bypassing a portion of original geothermal water to absorption chiller is not advisable. Besides power generation, air-conditioning, heat tracing, and heating/domestic hot water supply, the system can save about 6800 tons of oil for the OGT subsystem and recover more than 32 000 tons of oil each year.

    3. Numerical simulation and experimental investigation of a gas-liquid, double-acting traveling-wave thermoacoustic heat engine (pages 1963–1970)

      This paper proposes a gas–liquid, double-acting traveling-wave thermoacoustic heat engine, which has the advantages of both traditional thermoacoustic engine with long life span and the Stirling engine with high power density and high efficiency. By connecting three or four same thermoacoustic engines into a loop with a U-type liquid resonator, each engine can work in an ideal traveling-wave field, consequently bringing about high thermoacoustic conversion efficiency. Based on both the theoretical and experimental result, it is found that the novel gas–liquid, double-acting traveling-wave thermoacoustic heat engine is a very enabling technology due to its high reliability, simple structure, and high efficiency.

      A ground coupled heat pump system for a commercial building is presented. Experimental analysis and dynamic simulations have been performed. Energy and economic savings rather than traditional systems have been obtained. A sensitivity analysis for the ground coupled heat pump design parameters had been performed.

    6. Enhanced dye-sensitized solar cells performance of ZnO nanorod arrays grown by low-temperature hydrothermal reaction (pages 1992–2000)

      Crystalline well-aligned zinc oxide (ZnO) nanorod arrays were formed by low-temperature hydrothermal growth at 80 °C on seeded ITO/glass in a single reactive bath. Effect of hydrothermal growth time was investigated. Prolonged hydrothermal growth time (up to 24 h) resulted in higher conversion efficiency as longer ZnO nanorods with improved crystallinity were formed.

      The fluorescent spectroscopy displays the fluorescent spectra for fresh CuO/La2O3 catalyst; three significant excitation peaks at 280 nm, 445 nm, and 500 nm were observed. The fluorescent spectrum of the CuO/La2O3 catalyst after an activity test; significant excitation peaks at 265 nm were observed. Furthermore, these excitation peaks of the catalyst can be described as metal-enhanced fluorescence effects, in which the fluorescence is associated with the copper clusters of the CuO/La2O3 catalyst surface sites during the reaction.

      Thermodynamic models for iron and steel manufacturing system are established. Based on the analysis of theoretical and practical energy consumptions, energy-saving potentials of the processes are obtained. Energy-saving potentials and the optimal operating parameters for the different divided processes are obtained by using thermodynamic models. Based on the physical model of dynamic ordered production, simulation platform of production and network model of energy flow are developed for iron and steel manufacturing system.

    9. Analysis on embodied energy of China's export trade and the energy consumption changes of key industries (pages 2019–2028)

      Results of dynamic analysis on embodied energy of China's export show that in the succeeding texts, we have several important and valuable findings:

      1. The embodied energy of China's export trade is increased firstly and then has a downward trend, in which export is the main factor;
      2. The changes of embodied energy of the eight key industries are similar to the total embodied energy of export.
