Professor Daigger named chair of international committee on water resources

The International Advisory Committee (IAC) of the International Science & Technology Cooperation Center for Urban Alternative Water Resources Development has selected Professor Glen Daigger to act as the IAC Chairman.| Short Read

The committee is attached to the Xi’an University of Architecture and Technology in China. The role of the committee is to help the research center define the problems that it needs to focus on, where related state-of-the-art research is being conducted, and the role that it can play to meet research needs and contribute to advancing the international state of knowledge.

“Alternative water resources” refers to the development of water resources for human use in addition to the traditional water resources, which are surface water (rivers, lakes, and streams) and ground water. This is a term of art which refers to technologies and approaches such as rainwater harvesting, efficiency and demand management, water reclamation and reuse, and desalination.

“This is an extremely important topic for China as the country is dealing with water scarcity, especially in the northern half of the country, and many of the existing traditional water resources have become polluted. Thus, developing alternative water resources will be key to their continued economic development. Moreover, by 2030 half of the human population will live in areas where water is scare and alternative water resources must be relied on to provide a sufficient supply,” Daigger states.

The electrons absorb laser light and set up “momentum combs” (the hills) spanning the energy valleys within the material (the red line). When the electrons have an energy allowed by the quantum mechanical structure of the material—and also touch the edge of the valley—they emit light. This is why some teeth of the combs are bright and some are dark. By measuring the emitted light and precisely locating its source, the research mapped out the energy valleys in a 2D crystal of tungsten diselenide.

Mapping quantum structures with light to unlock their capabilities

Rather than installing new “2D” semiconductors in devices to see what they can do, this new method puts them through their paces with lasers and light detectors. | Medium Read
