He added that membrane wings in the future will also incorporate electro-active polymers that make them stiffen or relax, depending on an applied voltage, further increasing their performance.

|
Most 3-D printers, whether for metal or polymers, require some filing, milling or other tooling to take off surplus materials and smooth rough edges on a printed object.
|
|
The project will supply over 400,000 metric tonnes per year of rubber, thermoplastic polymers and carbon black for domestic markets and for export to Asia, according to the statement.

Meggitt's margins have been dragged down by its Polymers and Composites unit, part of the business that makes sophisticated engine parts which can withstand high temperatures from composite materials.
|
|
Rush says that's since become routine on the ISS, where astronauts have received blueprints from the ground hundreds of times to print tools and replacement parts using plastic polymers.
|
|
Another issue: It's not always clear what compounds a package is made of because manufacturing plastic polymers also yields a lot of byproducts that aren't necessarily tested for safety.
|
|
His work eventually led to today's Scotch Magic tape, and 3M has kept a tight seal on the recipe for its sandwich of polymers and carefully engineered chemicals ever since.
|
|
Solvay has steadily shifted from a base chemical and plastics company to one making speciality materials used by the oil and gas sector or in cosmetics and high-performance polymers.
|
|
Piezoelectric polymers in the rod convert this motion into electricity, with the frequency of the undulation (and therefore of the electric current) indicating the length of the rod's exposed part.
|
|
"It is all about chemicals and polymers, our core business products that we need to strengthen, but the second part is also technology," he said when asked about potential purchases.
|
|
But a team from HRL Laboratories in Malibu, California, has developed what they call a pre-ceramic resin, which they can 3D print much like regular polymers into complex shapes.
|
|
Now Anja Brandon, a student at Stanford University, and her research supervisor, Craig Criddle, have found that bacteria in the guts of mealworms can break down polymers much more quickly.
|
|
Mainly the shape-changing polymers are being considered for biomedical applications, like implants that would start off small when inserted and expand to their true size once inside a patient.
|
|
The chains in the polymer would thus assemble into layers, like the arterial walls the researchers hoped to copy, rather than strongly linked chains of some other liquid-crystal polymers.
|
|
The primer, which is available now for $32.50 on HSN, has a milky formula and employs flexible polymers that form an invisible shield to lock the scent onto your skin.
|
|
The HARP process allows a wide range of materials to be printed at large scale, including hundreds of different polymers, each one of which could be hard, soft or rubbery.
|
|
Pinatel said light materials are increasingly used as substitutes for metals in various industrial sectors such as transport and energy, all of which is lifting demand for plastics and polymers.
|
|
In the past, researchers have added dyes, antimicrobial agents, conductive polymers, and nanoparticles to silk, either by directly incorporating it into threads or by feeding it to the silkworms themselves.
|
|
The system measures 2 by 2.5 centimeters when unfolded and uses polymers with flexibility similar to that of the human skin that stretch and move along with the gastrointestinal tract.
|
|
The peripheral latanoprost was encased in slow-dissolving polymers, allowing for a steadier, continuous release into the eyes of the four monkeys that served as test subjects for the study.
|
|
Just a few months before Shandong Ruyi made its approach for Bally, it snapped up the Lycra brand from Invista, an American producer of polymers and fibers, for $13 billion.
|
|
So anyone who manufactures a "food contact substance," which includes chemical additives, coatings, paper, or polymers, must first get the okay from the FDA before putting it on the market.
