Carbon dioxide "breathing phenomenon" found in clay minerals

Japanese researchers have discovered a new phenomenon whereby carbonate ions (CO32−) in a clay mineral called "hydrotalcite" are repeatedly exchanged with carbon dioxide (CO2) in the air, quickly over several days, as if ...

Nanomechanical sensors detect cancer from breath

An array of functionalised membrane-type surface stress sensors (MSS) distinguishes cancer patients from healthy people through a signature response to breath samples.

Improving DNA-detecting transistors

Graphene-based transistors could soon help diagnose genetic diseases. Researchers in India and Japan have developed an improved method for using graphene-based transistors to detect disease-causing genes.

Map of diamond-boron bond paves way for new materials

Scientists in Japan have successfully recorded the atomic bonds between diamond and cubic boron nitride: the hardest known materials on earth. This feat could ultimately lead to the design of new types of semiconductors.
