Artificial glaciers increase water supply in northern Pakistan
Ice resembles a Buddhist pagoda and forms the shape of a corn that acts as a storage system. As temperatures rise, they melt steadily throughout the spring. At the foot of Pakistan’s incredibly high mountains, farmers, whitened by frost all year round, have created ice towers tackling water shortages. Warm winters as a result of climate change reduce snowfall and…

Artificial photosynthesis: Chemists develop dye stacks that mimic energy conversion in plants
What does a stack of four dyes synthesized in Würzburg look like? This represents an additional step into artificial photosynthesis as it absorbs light energy and travels quickly and efficiently into the stack. Credit: Leander Ernst / University of Wuerzburg Artificial photosynthesis allowed humans to use solar energy to combine carbon dioxide and produce hydrogen. Chemists from Würzburg and Seoul…

Research on artificial photosynthesis represents a step forward towards green hydrogen
Credit: Carbon (2024). doi:10.1016/j.carbon.2024.119951 How can we produce clean hydrogen without burning fossil hydrocarbons and other non-renewable energy sources? This can be done via photoelectrochemical or artificial photosynthesis. It uses sunlight and water, like photosynthesis, to obtain hydrogen without producing harmful emissions. A group of researchers from the Faculty of Physics at Trent University focuses precisely on this approach. This…
