A research team has made new discoveries that can expand additive manufacturing in industries that rely on strong metal parts, including aerospace.
Briefs: Robotics, Automation & Control
Taking inspiration from nature, a team of researchers at Queen Mary’s School of Engineering and Materials Science has successfully created an artificial muscle that seamlessly transitions between soft and hard states while also possessing the remarkable ability to sense forces and deformations.
Briefs: Lighting
Researchers have developed a colloidal synthesis method for alkaline earth chalcogenides. This method allows them to control the size of the nanocrystals in the material.
Briefs: Semiconductors & ICs
Researchers have fabricated a novel device that could dramatically boost the conversion of heat into electricity. If perfected, the technology could help recoup some of the recoverable heat energy that is wasted in the U.S. at a rate of about $100 billion each year.
Briefs: Materials
Researchers in the Lyding Group at the University of Illinois Urbana-Champaign have discovered an efficient, sustainable method for 3D-printing single-walled carbon nanotube films, a versatile, durable material that can transform how we explore space, engineer aircraft, and wear electronic technology.
Briefs: Manufacturing & Prototyping
A Penn State-led team of researchers have created a new process to fabricate large perovskite devices that is more cost- and time-effective than previously possible — and may accelerate future materials discovery.
Briefs: Materials
Researchers have created a way to make a 3D-printable nanocomposite polymeric ink that uses carbon nanotubes — known for their high tensile strength and lightness. This revolutionary ink could replace epoxies.
Briefs: Nanotechnology
Researchers are scaling up the production of vertically aligned single-walled carbon nanotubes that could revolutionize diverse commercial products ranging from rechargeable batteries, automotive parts and sporting goods to boat hulls and water filters.
Briefs: Design
Following nature's example, Lufthansa Technik and BASF have jointly developed the functional surface film AeroSHARK for commercial aircraft.
5 Ws: Design
A team of researchers at University of Houston have developed a deicing spray in which detachment can be accurately controlled and accelerated.
Briefs: Manufacturing & Prototyping
Researchers have developed a method of imprinting a hidden magnetic tag, encoded with authentication information, within manufactured hardware during the part fabrication process.
5 Ws: Robotics, Automation & Control
A team of researchers at Cornell Engineering has developed a soft robot that can detect when and where it was damaged — and then heal itself on the spot.
Briefs: Mechanical & Fluid Systems
Researchers produced a soft, mechanical metamaterial that can “think” about how forces are applied to it and respond via programmed reactions.
Briefs: Materials
This device could pave the way to higher-bandwidth wireless communications.
Briefs: Materials
NASA has developed a new metal matrix composite (MMC) that can repair itself from large fatigue cracks that occur during the service life of a structure.
Briefs: Wearables
The fibers measure subtle and complex fabric deformations.
Briefs: Defense
This new approach is useful for building radiation shields via the Z-grading method, the process of layering metal materials with different atomic numbers to provide radiation protection for protons, electrons, and x-rays.
Briefs: Materials
MIT researchers have developed a way of making even the most unlikely pairings of materials take on a desired level of wettability.
Briefs: Robotics, Automation & Control
The researchers created these sensing structures using just one material and a single run on a 3D printer.
Briefs: Manufacturing & Prototyping
One common limitation of AM has been that produced articles cannot be recycled without substantial energy costs.
Briefs: Software
The models allow users to optimize X-ray radiography setups, for the detection of crack and crack-like flaws, to penetrate various materials to show internal structures of parts.
Articles: Electronics & Computers
This column presents technologies that have applications in commercial areas, possibly creating the products of tomorrow.
Briefs: Materials
Applications include a smart fabric for exoskeletons, an adaptive cast that adjusts its stiffness as an injury heals, or a deployable bridge that could be unrolled and stiffened.
Briefs: Electronics & Computers
A simple change to the surface of perovskite removes a barrier to its functionality.
Briefs: Energy
The material remains effective as an energy harvester or sensor at temperatures to well above 572°F.
Briefs: Materials
The process predicts when and where microscopic cracks will occur before they become catastrophic.
Briefs: Lighting
These micro LEDs can be folded, twisted, cut, and stuck to different surfaces.
Briefs: Power
Vanillin is converted into a redox-active electrolyte material for liquid batteries.
Briefs: Materials
Hydrogen has emerged as an important carrier to store energy generated by renewable resources, as a substitute for fossil fuels used for transportation, in the production of ammonia, and for other industrial applications.
