Removing pathogens from drinking water is especially difficult when the germs are too tiny to be caught by conventional filters. Researchers are developing new materials and processes to free water from pathogenic microorganisms such as viruses.
Chemists have developed a strategy for the atomically precise synthesis of fully conjugated zigzag-edged carbon nanobelts. The obtained molecule is acknowledged as one of the first fully characterised synthetic segments of zigzag-edged carbon nanotube. Such molecular structures have been elusive targets for synthetic chemists for the past 35 years.
The ability to turn on and off a physical process with just one photon is a fundamental building block for quantum photonic technologies. Realizing this in a chip-scale architecture is important for scalability.
