Hydrogen power could have a bright future.
A new material helps to make clean fuel from water.
Scientists in Japan have found a more efficient way to extract hydrogen, the ultimate ’green’ fuel, from water. They have developed a material that uses sunlight to break water molecules into their constituent elements of hydrogen and oxygen1.
The material is not yet efficient enough to be commercially viable, but its inventors believe that it can be improved. If they are right, hydrogen may soon be on tap just like natural gas.
Zhigang Zou of the National Institute of Advanced Industrial Science and Technology in Tsukuba, Japan, and co-workers have developed a photocatalyst that seems to be very stable, showing no evidence of degradation after extended use. It is not terribly efficient - over 99% of the light energy is wasted rather than used to split water - but this is respectable when compared with the competition.
The material, like the majority of visible-light photocatalysts, is a metal oxide, which generates hydrogen and oxygen when immersed in water in sunlight. The oxide contains indium, nickel and tantalum; the efficiency depends on the amount of nickel in the material.
Zou and colleagues believe that they can improve the efficiency by increasing the surface area of the photocatalyst - making it porous, for example, or grinding it into a fine powder - and by further tinkering with the chemical composition.

Proteins must be folded correctly to fulfill their molecular functions in cells. Molecular assistants called chaperones help proteins exploit their inbuilt folding potential and reach the correct three-dimensional structure. Researchers at the Max Planck Institute of Biochemistry (MPIB) have demonstrated that actin, the most abundant protein in higher developed cells, does not have the inbuilt potential to fold and instead requires special assistance to fold into its active state. The chaperone TRiC uses a previously undescribed mechanism to perform actin folding. The study was recently published in the journal Cell.
Actin is the most abundant protein in highly developed cells and has diverse functions in processes like cell stabilization, cell division and muscle...
