Tunable metamaterialA tunable metamaterial is a metamaterial with a variable response to an incident electromagnetic wave. This includes remotely controlling how an incident electromagnetic wave (EM wave) interacts with a metamaterial. This translates into the capability to determine whether the EM wave is transmitted, reflected, or absorbed. In general, the lattice structure of the tunable metamaterial is adjustable in real time, making it possible to reconfigure a metamaterial device during operation.
Lab-on-a-chipA lab-on-a-chip (LOC) is a device that integrates one or several laboratory functions on a single integrated circuit (commonly called a "chip") of only millimeters to a few square centimeters to achieve automation and high-throughput screening. LOCs can handle extremely small fluid volumes down to less than pico-liters. Lab-on-a-chip devices are a subset of microelectromechanical systems (MEMS) devices and sometimes called "micro total analysis systems" (μTAS). LOCs may use microfluidics, the physics, manipulation and study of minute amounts of fluids.
Second Cold WarThe Second Cold War, Cold War II, or the New Cold War are terms that refer to heightened geopolitical tensions in the 21st century. They have been used to describe the tense relations between the United States and China and, similarly, between the United States and Russia, the primary successor state of the former Soviet Union, which took part in the original Cold War. The terms are sometimes used to describe tensions in multilateral relations.
Cold war (term)A cold war is a state of conflict between nations that does not involve direct military action but is pursued primarily through economic and political actions, propaganda, acts of espionage or proxy wars waged by surrogates. This term is most commonly used to refer to the American-Soviet Cold War of 1947–1991. The surrogates are typically states that are satellites of the conflicting nations, i.e., nations allied to them or under their political influence.
