Mott insulators are a peculiar class of materials with structures that should theoretically conduct electricity, but that are instead insulators. These materials contain strongly correlated electrons, which can generate highly ...
The standard model of particle physics only accounts for 20% of matter in the universe. Physicists have theorized that the remaining 80% is made up by so-called dark matter, which consists of particles that do not emit, absorb ...
(Phys.org) —Although sodium-ion (Na-ion) batteries don't perform as well as lithium-ion (Li-ion) batteries, they have the potential to be a cheaper alternative. In a new study, scientists have designed a new cathode for ...
(Phys.org) -- By connecting a new flexible, thin-film Li-ion battery to a flexible organic LED, a team of researchers from South Korea has demonstrated the first fully functional all-flexible electronic system. In other ...
(Phys.org) -- By converting sunlight into chemical energy, artificial photosynthesis systems could potentially produce renewable, nonpolluting fuels and chemicals for a wide variety of uses. But developing an efficient solar-to-fuel ...
Theoretical physicists at Utrecht University, together with experimental physicists at Sogang University in South Korea, have succeeded in building an artificial synapse. This synapse works with water and salt and provides ...

Astronomers have conducted a photometric and spectroscopic study of an Algol-type binary, known as XZ Ursae Majoris (or XZ UMa for short). Results of the study, presented in a paper published December 21 on the pre-print ...
By analyzing the data from the SPICY catalog and from NASA's WISE spacecraft, an international team of astronomers has discovered four new eruptive young stellar objects (YSOs). The finding was presented in a research paper ...
Earthquakes often occur along plate boundaries, when sudden movements of the "stuck" plates release elastic strain energy, sending out seismic waves that result in the ground shaking familiar to many worldwide. More rarely, ...
South Korea, officially the Republic of Korea (ROK) (Korean: 대한민국, pronounced [tɛːhanminɡuk̚] ( listen)) and often referred to as Korea, is a country in East Asia, located on the southern half of the Korean Peninsula. Also known as the "Land of the Morning Calm", it is neighbored by China to the west and Japan to the east, bordering North Korea to the north. Its capital is Seoul, the second largest metropolitan city in the world and a major global city. South Korea lies in a temperate climate region with a predominantly mountainous terrain. Its territory covers a total area of 100,032 square kilometers and has a population of over 48 million, making it one of the most densely populated regions in the world.
South Korea is a presidential republic consisting of 16 administrative divisions. Archaeological findings show that the Korean Peninsula was occupied as early as the Lower Paleolithic period. Korean history begins with the founding of Gojoseon in 2333 BCE by Dangun. Following the unification of Three Kingdoms of Korea under Silla 668 CE, Korea existed as a unified nation Goryeo and Joseon Dynasty until the end of the Korean Empire in 1910. After liberation and division in 1948, South Korea was ruled by a series of autocratic governments until its transition to democracy in the 1980s. Following the Korean War, the South Korean economy grew significantly, transforming the country into a major global economy. This is known as the Miracle on the Han River and the country became one of the Four Asian Tigers.
South Korea is a developed country with the smallest gap between rich and poor in high-income Asian economies. It is a High-income OECD member, having the fourth largest economy in Asia and the 15th largest in the world. South Korea is the world leader in innovation among major economies and a leader in technologically advanced goods such as electronics, automobiles, ships, machinery, petrochemicals and robotics, headed by Samsung, LG and Hyundai-Kia. It is a member of the United Nations, WTO, OECD and G-20 major economies. It is also a founding member of APEC and the East Asia Summit, and a major non-NATO ally of the United States. In the 21st century, there has been increased interest in Korean culture throughout the world, also known as the Korean Wave.
