Researchers demonstrated the first fully 3D-printed, droplet-emitting electrospray engine. The low-cost device can be fabricated more quickly than traditional thrusters, potentially from on board a ...

Instead, clamp it to an unpainted metal surface under ... the Black Diamond Spot 400 provides exactly what you need: a bright beam, easy-to-navigate buttons, and long-lasting battery life.

An electrospray engine applies an electric field to a conductive liquid – generating a high-speed jet of tiny droplets that can propel a spacecraft. These miniature engines are ideal for small ...

Furin is identified as the key enzyme responsible for cleaving the apelin precursor. Inhibiting this cleavage could serve as ...

The best bike lights fall into one of two categories. The first - 'be seen' lights - are bright enough to attract the attention of other road users around you, but not quite bright enough to light ...
