Ikuko Akimoto and colleagues point out that traditional approaches to breaking down water, which consists of hydrogen and oxygen, involve use of expensive catalysts or electric current passed through water. Since economical production of hydrogen from water could foster a transition from coal, oil and other fossil fuels, scientists have been searching for less expensive catalysts.
Those materials speed up chemical reactions that otherwise would not work effectively. Based on hints from research decades ago, the scientists decided to check out the ability of carbon powder and charcoal powder, which are inexpensive and readily available, to help split hydrogen gas from oxygen in water.
Akimoto's team tested carbon and charcoal powders by adding them to water and beaming a laser in nanosecond pulses at the mixtures. The experiment generated hydrogen at room temperature without the need for costly catalysts or electrodes. Its success provides an alternative, inexpensive method for producing small amounts of hydrogen from water.

A widely used diabetes medication combined with an antihypertensive drug specifically inhibits tumor growth – this was discovered by researchers from the University of Basel’s Biozentrum two years ago. In a follow-up study, recently published in “Cell Reports”, the scientists report that this drug cocktail induces cancer cell death by switching off their energy supply.
The widely used anti-diabetes drug metformin not only reduces blood sugar but also has an anti-cancer effect. However, the metformin dose commonly used in the...
A research team from the University of Zurich has developed a new drone that can retract its propeller arms in flight and make itself small to fit through narrow gaps and holes. This is particularly useful when searching for victims of natural disasters.
Inspecting a damaged building after an earthquake or during a fire is exactly the kind of job that human rescuers would like drones to do for them. A flying...
