Light irradiation plays an important role in the growth of microalgae and their nutrient composition. To elucidate effect different LED lights (red, orange, green, blue, purple, simulated sunlight, white) on main nutritional compositions Isochrysis zhanjiangensis, growth, fatty acid composition, soluble carbohydrate, protein contents were studied. The results show that I. zhanjiangensis grew fa...

We review recent progress towards increasing solar cell efficiencies beyond the Shockley-Queisser efficiency limit. Four main approaches are highlighted: multi-junction cells, intermediate-band cells, hot carrier cells and spectrum conversion. Multi-junction cells use multiple solar cells that selectively absorb different regions of the solar spectrum. Intermediateband cells use one junction wi...

Pinus pseudostrobus Lindl. is a species endemic to Mexico and widely used in reforestation programmes, as it highly adapted poor, shallow, limestone soils has high commercial importance. However, necessary preserve this genetic material since trouble due rates of deforestation, land use change, forest fires, so have effective strategies obtain good quality seedlings. Due the properties LED (lig...
