New X-ray method isolates faint signals from water at material surfaces

A research team from Toyohashi University of Technology, the Institute for Molecular Science and the Institute of Science Tokyo, led by Yu Kinjo and professor Ryugo Tero of Toyohashi University of Technology, has developed a new method to investigate the state of water near material surfaces using X-rays. By combining X-ray absorption spectroscopy with data analysis, the researchers separated the weak signals of interfacial water from those of the much larger amount of surrounding water.
