A recently developed 1,500-lbf (6,672-N) thrust-class liquid oxygen/liquid methane (LO2/LCH4) rocket engine was tested at both sea level and simulated altitude conditions. Sea-level tests were conducted using both a static horizontal test bed, and...

MIT researchers have developed a printable origami-inspired robot that, when heated, folds itself up from a flat sheet of plastic. The robot weighs a third of a gram and measures about a centimeter from front to back.

A synchronous computer from Stanford University operates using the unique physics of moving water droplets. The work combines the manipulation of droplet fluid dynamics with a fundamental element of computer science – an operating clock.

A new technique from MIT researchers boosts production of nanofibers fourfold, while cutting energy consumption by more than 90 percent. Potential nanofiber applications include solar cells, water filtration, and fuel cells.

A MEMS (microelectromechanical systems) micro-translation stage (MTS) with large linear travel capability was developed that uses capacitive electrostatic forces created by stators arranged linearly on both sides of a channel, and matching rotors on a moveable shuttle for precise...

A highly efficient way to cool solid-state crystal lasers was developed. This thin-film evaporative cooling technique offers higher optical efficiencies and monochromatic quality than traditional conductive cooling techniques. Developed for use in side-pumped 2.0- micron laser systems used in...

There is a need for experimental techniques that have low cost and rapid turnaround. It is also necessary to obtain quantitative information from such a method. Previous methods are either lacking in quantitative information such as dye or smoke injection, or require considerable set-up and cost...

CubeSat appendices such as solar panels and antennas often need to be constrained by a release mechanism during launch. These appendices are then deployed once the desired orbit is reached. The usual constraint method used is a combination of an unpredictable/...

MIT Media Laboratory researchers are developing a wearable device that turns the user’s thumbnail into a miniature wireless track pad.

Soft nanoparticles from a University of Pennsylvania research team stick to the plane where oil and water meet, but do not stick to one another. The interface presents a potentially useful set of properties. The nanoparticles freely move past one another while being confined to the interface, effectively acting as a 2D...

Engineers at NASA's Marshall Space Flight Center in Huntsville, Alabama, unboxed some special cargo from the International Space Station on April 6: the first items manufactured in space with a 3D printer.
