When rain falls on a lotus leaf, the leaf doesn't get wet. Thanks to its special structure, the water drops roll off without wetting the surface. Artificial materials can be made water-repellent, too. It is, however, extremely challenging to produce a surface with switchable wetting. Show More Summary
By Tim Radford / Climate News Network Renewable energy experts and microbiologists have teamed up to create a super-efficient artificial leaf that uses photosynthesis to produce carbon-neutral liquid fuels.
Suck it, plants—this bionic leaf has got you beat ten times over! A team of researchers at Harvard University, led by Daniel Nocera and Pamela Silver, have been perfecting this leaf's ability to perform artificial photosynthesis.
The latest version of the artificial leaf is ten times more efficient than photosynthesis.
Harvard University's Daniel Nocera is a busy man. Last week, we reported on his announcement of a superbug that consumes carbon dioxide and creates fuel, a major development in energy technology. Now, the news is out that the "bionic...Show More Summary

Over the last few years, great strides have been made in creating artificial leaves that mimic the ability of their natural counterparts to produce energy from water and sunlight. In 2011, the first cost-effective, stable artificial leaves were created, and in 2013, the devices were improved to self-heal and work with impure water. Show More Summary
The Harvard chemist who gave us the artificial leaf has genetically engineered bacteria to absorb hydrogen and carbon dioxide and convert them into fuel alcohol. Now he reports the process converts sunlight ten times more efficiently than plants do.
By using a photoelectrode in which gold nanoparticles are loaded on an oxide semiconductor substrate, a research has worked to develop a method of artificial photosynthesis that may prove to be an excellent light energy conversion system.
The "artificial leaf" consists in principle of a solar cell that is combined with further functional layers. These act as electrodes and additionally are coated with catalysts. If the complex system of materials is submerged in water and illuminated, it can decompose water molecules. Show More Summary
A process for providing sensitive semiconductors for solar water splitting ('artificial leaves') with an organic, transparent protective layer has been developed by researchers. The extremely thin protective layer made of carbon chains is stable, conductive, and covered with catalyzing nanoparticles of metal oxides. Show More Summary
The team was able for the first time to produce a hybrid structure that converts 12 per cent of the incident solar energy into the form of hydrogen. The results have now been published in Advanced Energy Materials. read more
An international team has succeeded in considerably increasing the efficiency for direct solar water splitting with a tandem solar cell whose surfaces have been selectively modified. The new record value is 14 percent and thus tops the previous record of 12.4 percent, broken now for the first time in 17 years.
A new "artificial leaf" that can turn sunlight and water directly into hydrogen and oxygen is shattering performance and stability records
The big challenges standing in the way of a full frontal assault on petroleum by the clean energy industry are the cost of production and a dearth of ways to store the energy after its produced. But recently a team from Caltech’s Joint Center for came
To unlock the secret to renewable energy, science is taking a cue from nature.
A new solar fuel generation system, or artificial leaf, safely creates fuel from sunlight and water with record-setting efficiency and stability.
When we think of solar power, we usually think of solar panels but we should really be thinking about plants. After all, plants are the original solar power generators, turning the sun’s rays into energy through the process we all learned about in at
New research out of Melbourne has broken records and brought emission-less hydrogen energy a step closer to commercial production. Thom Mitchell reports.
