Behind the label—study shows diamond rotary instruments marketed for removing zirconia restorations do not perform better than conventional ones

By Lisa McDonald / September 30, 2022

Removal of zirconia dental restorations is challenging and time consuming due to their high strength. Manufacturers offer diamond rotary instruments marketed specifically for removing zirconia restorations, but a new study reaffirmed that these instruments do not perform better or generate less heat than conventional ones.

Video: First-of-their-kind drones can 3D print in flight

By Lisa McDonald / September 28, 2022

Using additive manufacturing to repair objects in difficult-to-access locations, such as at the top of tall buildings, is not convenient because the 3D-printing equipment cannot be transported there easily. An international team of researchers developed a swarm of cooperative, 3D-printing drones that can print materials for building or repairing structures while flying.

Nanostructured diamond capsules maintain high-pressure samples for materials analysis

By Lisa McDonald / September 23, 2022

Preserving high-pressure states of novel materials at ambient conditions is a long-sought-after goal for fundamental research and practical applications. A recent joint project by researchers in China and the United States showed that properties of high-pressure materials can be maintained in free-standing, nanostructured diamond capsules without the support of traditional bulky pressure vessels.

Next-gen spacecraft: In-development solid oxide fuel cells offer bipropellant enabled electrical power supply

By Lisa McDonald / September 20, 2022

Mass and volume limitations make it challenging to load a spacecraft with all the equipment needed for a mission. An effort led by the Air Force Research Laboratory is developing a solid oxide fuel cell that converts chemical energy in a spacecraft’s bipropellant into electricity, thereby allowing an existing spacecraft component to be used as an auxiliary power supply.
