Megan MacArthur, NASA's Mission 65 pilot to the International Space Station, works in the Zero Gravity Science Glove Box and exchanges samples for an experiment called Barrier Sealed Ampoule Coagulation, or SUBSA. The physics experiment investigates experimental methods for coagulating solutions in zero gravity and is expected to lead to reduced fluid movement in the solution, Which will allow for a better distribution of the components and the potential to improve the technology used to produce semiconductor crystals.

The space agency says that the industry alone will not be able to move forward and it is required to cooperate with the government and academia. This can help solve bottlenecks that slow down progress in the field
The picture shows an energy band diagram of a micro-resonator based on a GaAs semiconductor as studied in the experiment, in which a quantum condensation of light-matter coupled quasi-particles called exciton-polaritons (exciton-polaritons) - through two-photon absorption. The achievement paves the way for new coherent control schemes and the realization of an efficient laser source in the terahertz (THz) range of electromagnetic radiation

First observation of "two-photon absorption for quantum condensation"

The achievement may accelerate research in new quantum technologies and developments in security, biological sensing, wireless communication and more

Organic topological insulators capable of transmitting information at the speed of light and which consist of a thin molecular layer (on the left) that resembles a sort of chicken coop fence wire while conducting electricity along the right edge of this layer (the blue line) - when the electrons can also carry information in the form of "down" or "up" spin ".
