In this paper, heat transfer and flow in a lean-to passive solar greenhouse has been studied. A mathematical model based on energy equilibrium and a one-dimensional mathematical model for the unsaturated porous medium have been founded and developed to predict the temperature and moisture...

Flexible solid-state dye sensitized solar cell is an important milestone for low-cost, large scale fabrication of dye-sensitized solar cells. Flexible solid-state dye-sensitized solar cell is fabricated for the first time on titanium substrates using D102 sensitizer and a sputtered platinum...

We explored the application of Low-Intensity Pulsed Ultrasound (LIPUS) technology to improve the metabolic activity of microorganisms. In this study we showed that LIPUS improves bio-ethanol production from lignocellulosic biomass. We determined specific LIPUS conditions to increase the...

All-glass evacuated collector tube has the configuration of two concentric Borosilicate glass tubes with sputtered Al-N/Al selective surfaces developed in Tsinghua University, Beijing, and mass produced now. Installed evacuated collector system with Various manifolds for domestic hot water....

This study evaluated hydrogen generation through the hydrolysis of an Al/NaBH4/Co/NaAlO2 system. Hydrogen generation performance can be altered by changing the Al/NaBH4 mass ratios, Co amount and NaAlO2 concentration. The optimized composite can achieve a hydrogen yield of more than 90% within...
