Imperial College

Imperial College is developing a rocket thruster called the Iridium Catalysed Electrolysis CubeSat Thruster (ICE-Cube Thruster) that is so small that it can only be fabricated using techniques originally designed for making silicon chips.

Firefighters have a dangerous job at the best of times, but especially so when they're first entering burning buildings. A new flame-resistant drone could help, by scouting structures to let firefighters know what they'll be up against.

Building structures in difficult-to-reach locations is a daunting task, as bringing in the cranes, scaffolding and whatnot can be difficult. That's why scientists are creating a bee-inspired system, which uses flying 3D-printing drones to do the job.

Although aerial drones can travel much faster than their underwater counterparts, they certainly aren't as good at gathering water-related data. The MEDUSA multi-rotor drone addresses this conundrum, by landing on the water and deploying an underwater pod.

While we have heard of a few aerial drones that are also able to operate underwater, a new one takes that concept considerably further. Using a fish-inspired suction disc, it can hitch rides underwater – possibly even on submarines – to save power.

Researchers have developed a simple new way to make material surfaces with intricate nanoscale textures, all inspired by nature. Different patterns have a range of applications, like making antimicrobial surfaces or reducing ship hull friction.

There is a growing field of research dedicated to so-called "living materials" that might one day allow structures to repair themselves, and a new example adapts this thinking to bacteria-based building blocks that are fit for a range of purposes.

As anyone with arthritis will know, cartilage plays a vital role in allowing our joints to move freely. Scientists have now replicated its qualities in a synthetic self-lubricating material, that only needs occasional infusions of water.

Perovskite solar is gaining much attention in solar cell research, but there are greener alternatives in the works. Scientists have just uncovered a new use for these materials, learning they can harvest energy from indoor lighting with high efficiency.

When conducting environmental studies in hard-to-access locations, scientists will often set up networks of small data-logging sensors. Deploying those sensors can be hard, though, which is why a dart-shooting drone is being developed to do the job.

It would be handy if there was a filtration medium that could be electronically "switched" to capture particles of different sizes. It turns out that there soon may be, thanks to a newly-developed conductive polymer that changes state, on demand.

Scientists have developed a flying fish-inspired robot that can generate enough power to launch itself out of the water by using the water itself as a fuel source.
