ColdXray’s graphene-based cold cathodes are transforming space propulsion by providing highly efficient electron emission for electric thrusters. Our technology enhances satellite longevity, reduces energy consumption, and ensures stable, reliable operation in extreme space conditions.

Our graphene-based cathodes also revolutionize X-ray generation by eliminating the need for traditional filament heating, making X-ray systems more compact, durable, and energy-efficient. This innovation enhances imaging in healthcare, security screening, and industrial non-destructive testing.

Ability to harness quantum speed gains now within sight after researchers solve massive simulation problem in a heartbeat

The use of a quantum-inspired algorithm to calculate the unworkably vast potential properties of quantum materials is an early example of how quantum technology can be used to improve itself. The discovery could have future applications in dissipationless technology, for example to mitigate data centre heating.
