Solar‐Driven Ammonia Synthesis From Nitrate Reduction Paired With CO2 Capture for Sustainable Agriculture via a Robust CuPd Heterojunction

Angewandte Chemie, EarlyView.
Laser‐assisted synthesis of CuPd amorphous/crystalline heterojunction demonstrates >80% Faradaic efficiency for nitrate‐to‐ammonia electroreduction across wide potential windows. The integrated solar‐powered electrolyzer achieves 6% solar‐to‐ammonia energy efficiency at 0.4 sun, 6–20 mg h−1 CO2 capture rate, and stability exceeding 100 h.

The development of local solar irradiance for outdoor computer graphics rendering [PDF]

, 2005
Atmospheric effects are approximated by solving the light transfer equation, LTE, of a given viewing path. The resulting accumulated spectral energy (its visible band) arriving at the observer’s eyes, defines the colour of the object currently on the ...

Simulation of Dimmer Circuit for Daylight Harvesting

Energy Procedia, 2012
AbstractIn this paper a fuzzy based dimmer circuit model for daylight harvesting is proposed. The model incorporates the variable daylight intensity and number of occupants in a room. The dimmer circuit controls the switching ON and OFF of LEDs (light emitting diode) in a room corresponding the daylight intensity and occupants while the required level ...
