Three π-A-porphyrins containing long alkoxyl chains attached to the ortho position of phenyl ring and a phenyl carboxylate acid or acrylic acid at the meso position of porphyrin were synthesized. All compounds were characterized by 1H NMR and mass spectrometry. Optical and electrochemical...

This paper presents an experimental and analytical study on incorporation of thermoelectric modules with glass evacuated-tube heat-pipe solar collectors. The integrated solar heat-pipe/thermoelectric module (SHP-TE) can be used for combined water heating and electricity generation. The...

A simulation model is presented to evaluate the operational benefits of Tianhuangping Pumped Storage Hydro-Plant (TPSHP) in the Shanghai electrical network. The benefits from the hydro-plant include the electricity from the pumped water, the efficiency improvement of the overall units and the...

The assembly and hoisting process of the wind turbine rotor in an open wind environment are regarded to improve the hoisting safety, efficiency and quality. The wind turbine rotor model of a 1.5 MW wind turbine are given, and the hoisting forces of the wind turbine rotor in different poses with...

This paper presented a case study on performance analysis of ground water-source heat pump system (GWHP) for a hotel building retrofit. Splitting air-conditioner was used for cooling and coal fired boiler was used for heating in original system. The GWHP system could save electricity energy and...

A pilot-scale anaerobic co-digestion research study is presented to elucidate the feasibility of developing anaerobic digestion (AD) as an effective disposal method for municipal biomass waste (MBW) in China, focusing on biogas production and greenhouse gas (GHG) reduction. Food waste,...

Municipal biomass waste is regarded as new available energy source, although it could cause serious environmental pollution. Generally, biogas recovery by anaerobic digestion was seen as an ideal way to treat biomass waste. Different types of biomass waste have different biogas production...
