The Ministry of Trade, Industry and Energy announced on Tuesday... that new methods developed by local scientists,... of defining and evaluating properties of graphene and silver nanoparticles,... have been accepted as international standards.
The Korean Agency for Technology and Standards proposed two new methods to the International Organization for Standardization, an international standard-setting body... after a five-year review and verification process.
Graphene is a single, thin layer of graphite,... the soft, flaky material used in pencil lead.
Stronger than steel and thinner than paper,... the nanomaterial can be used to produce a range of high-tech goods,... including high-speed semiconductor devices, displays and secondary batteries.
Silver nanoparticles are microscopic grains of silver... between 1 nanometer and 100 nanometer in size.
One nanometer is equivalent to one-billionth of a meter.
The substance is used to manufacture solar cells, textiles and displays.
This achievement is especially notable, as Korea was competing against the world leaders in this discipline,... such as the United States, the United Kingdom and Japan.
Japan is also known to have devised new standards... to measure and evaluate the properties of silver nanoparticles... in direct competition with Korea.
