UBC’s nature-based solution with locally available earthen materials could aid in building climate-resilient infrastructure.

In-Space Manufacturing of Self-Replicating Machines

How do we get to a future of self-replicating, Von Neumann space probes? What are some of the steps required to convert the Asteroid Belt into a partial Dyson Sphere? The answer lies in ISAM or in-space servicing assembly and manufacturing, 3D printing on-orbit, and fully automated, ‘lights-out’ production on-Earth.

Videos of the Month

See the videos of the month, including one on NASA’s Europa Clipper spacecraft; one on the Dragonfly rotorcraft and how it was tested multiple times by Johns Hopkins Applied Physics Laboratory in wind tunnel facilities; one on a team from Los Alamos National Laboratory going to the Haughton Impact Crater on Devon Island, Canada — a frigid environment similar to Mars; and one on engineers at the U.S. Naval Research Laboratory’s Naval Center for Space Technology recently completing robotic payload component level testing.

The Heat Is on Data Storage — Which Is Now OK

A University of Pennsylvania team demonstrated memory technology capable of enduring temperatures as high as 600 °C — more than twice the tolerance of any commercial drives on the market — and these characteristics were maintained for more than 60 hours.

Researchers at the Department of Energy’s Oak Ridge National Laboratory have improved on approaches that dissolve a battery in a liquid solution in order to reduce the amount of hazardous chemicals used in the process.

A Novel Technique to Create Energy-Efficient Microelectronics

Microelectronics face a key challenge because of their small size. To avoid overheating, microelectronics need to consume only a fraction of the electricity of conventional electronics while still operating at peak performance. Researchers have achieved a breakthrough that could allow for a new kind of microelectronic material to do just that.

Low-Voltage, Low-Power Pressure Sensors for Monitoring Health

Researchers have found ways to develop soft OECTs for wearable pressure sensors. They first experimented with a solid type of gating substance: a charged, gelatinous substance called an ionic hydrogel. Read on to learn more.

Self-Powered Sensor for Harvesting Magnetic Energy

Because it requires no battery that must be recharged or replaced, and because it requires no special wiring, such a sensor could be embedded in a hard-to-reach place, like inside the inner workings of a ship’s engine. There, it could automatically gather data on the machine’s power consumption and operations for long periods of time.

New Adhesive Tape Easily Picks Up and Sticks Down 2D Materials

A research team from Kyushu University, in collaboration with Japanese company Nitto Denko, has developed a tape that can be used to stick 2D materials to many different surfaces, in an easy and user-friendly way.
