The already unclear lines separating research from development are getting even blurrier as more companies allocate some part of their R&D budget to take on riskier projects, and invest in the necessary infrastructure to manage these riskier activities. New products are now being launched out of recently formed "Innovation" organizations", and more are coming from existing “Advanced Development" organizations.
Researchers at McGill Univ. have developed a new, low-cost method to build DNA nanotubes block-by-block, a breakthrough that could help pave the way for scaffolds made from DNA strands to be used in applications such as optical and electronic devices or smart drug delivery systems. Many researchers, including the McGill team, have previously constructed nanotubes using a method that relies on spontaneous assembly of DNA in solution.
Scientists at the Univ. of Sheffield have succeeded in using a 3-D printed guide to help nerves damaged in traumatic incidents repair themselves. The team used the device to repair nerve damage in animal models and say the method could help treat many types of traumatic injury.
Graphene is often touted as a replacement for silicon in electronic devices due to its extremely high conductivity and unbeatable thinness. But graphene isn’t the only 2-D material that could play such a role. Univ. of Pennsylvania researchers have made an advance in manufacturing one such material, molybdenum disulphide.
Researchers have revealed previously unobserved behaviors that show how details of the transfer of heat at the nanoscale cause nanoparticles to change shape in ensembles.
Researchers at the Univ. of Illinois at Urbana-Champaign have developed a unique single-step process to achieve 3-D texturing of graphene and graphite. Using a commercially available thermally activated shape-memory polymer substrate, this 3-D texturing, or "crumpling," allows for increased surface area and opens the doors to expanded capabilities for electronics and biomaterials.
In 2013, battle lines were drawn. Two stark competitors were looking to speed repairs and cut costs on parts for gas turbines. First to the drawing board was GE, who started using 3-D printing technology at its Global Research Center in Niskayuna, N.Y., to produce more than 85,000 fuel nozzles for its anticipated LEAP engine technology.
The engineering world just became even more colorful. Northwestern Univ. researchers have created a new technique that can transform silver into any color of the rainbow. Their simple method is a fast, low-cost alternative to color filters currently used in electronic displays and monitors.
People have been making rubber products from elastic bands to tires for centuries, but a key step in this process has remained a mystery. In a report, scientists have described this elusive part of rubber production that could have major implications for improving the material and its uses. Their findings, if used to improve tire performance, for example, could mean higher gas mileage for consumers and less air pollution.
A two-part water-based gel made of synthetic DNA could bring the inventors of a 3-D bio printer closer to being able to print organs for transplant, or to replace animal testing. They faced two main challenges: finding a matrix or scaffold to support the live cells in 3-D, and being able to produce a consistent product which would not be rejected by transplant recipients.
Imagine printing out molecules that can respond to their surroundings. A research project at the Univ. of Washington merges custom chemistry and 3D printing. Scientists created a bone-shaped plastic tab that turns purple under stretching, offering an easy way to record the force on an object.
Researchers building a new underwater robot they’ve dubbed the “Millennium Falcon” certainly have reason to believe it will live up to its name. The robot will deploy instruments to gather information in unprecedented detail about how marine life interacts with underwater equipment used to harvest wave and tidal energy.
A novel approach to growing nanowires promises a new means of control over their light-emitting and electronic properties. In a recent issue of Nano Letters, scientists from Lawrence Berkeley National Lab demonstrated a new growth technique that uses specially engineered catalysts. These catalysts, which are precursors to growing the nanowires, have given scientists more options than ever in turning the color of light-emitting nanowires.
People typically consider doing the laundry to be a boring chore. But laundry is far from boring for artificial intelligence (AI) researchers. To AI experts, programming a robot to do the laundry represents a challenging planning problem because current sensing and manipulation technology is not good enough to identify precisely the number of clothing pieces that are in a pile and the number that are picked up with each grasp.
Scientists have developed an octopus-like robot, which can zoom through water with ultra-fast propulsion and acceleration never before seen in man-made underwater vehicles. Most fast aquatic animals are sleek and slender to help them move easily through the water but cephalopods, such as the octopus, are capable of high-speed escapes by filling their bodies with water and then quickly expelling it to dart away.
When disaster strikes, it's important for responders and emergency officials to know what critical infrastructure has been damaged so they can direct supplies and resources accordingly. Doug Stow, a geography professor from San Diego State Univ., is developing a program that uses before-and-after aerial imagery to reveal infrastructure damage in a matter of minutes.
Many people imagine robots today as clunky, metal versions of humans, but scientists are forging new territory in the field of “soft robotics”. One of the latest advances is a flexible, microscopic hand-like gripper. The development could help doctors perform remotely guided surgical procedures or perform biopsies. The materials also could someday deliver therapeutic drugs to hard-to-reach places.
A team of New York Univ. physicists has developed a method to monitor the properties of microscopic particles as they grow within a chemical reaction vessel, creating new opportunities to improve the quality and consistency of a wide range of industrial and consumer products. Their work, which appears in Soft Matter, offers benefits for commodities ranging from food and pharmaceuticals to perfumes and cosmetics.
By combining micro-imprinting and electro-spinning techniques, researchers at Shanghai Univ. have developed a vascular graft composed of three layers for the first time. This tri-layered composite has allowed researchers to utilize separate materials that respectively possess mechanical strength and promote new cell growth, a significant problem for existing vascular grafts that have only consisted of a single or double layer.
The editors of R&D Magazine are looking for speakers to participate in a webinar on “Using Multiple Materials in 3D Printing.” Candidates are asked to give a 15-min PowerPoint-based talk over the phone on their experiences in fabricating 3D printed products using multiple materials or developing the processes and/or technologies to accomplish this.
Grasping an object involves a complex network of brain functions. First, visual cues are processed in specialized areas of the brain. Then, other areas of the brain use these signals to control the hands to reach for and manipulate the desired object. New findings suggest that the cerebellum may play a critical role. Findings could lead to advancements in assistive technologies benefiting the disabled.
A device, possibly an unmanned aerial drone, was found on the White House grounds during the middle of the night while President Barack Obama and the first lady were in India, but his spokesman said today that it posed no threat. It was unclear whether their daughters, Sasha and Malia, were at home at the time of the incident with their grandmother, Marian Robinson, who also lives at the White House.
Researchers in Japan revealed that improvements should soon be expected in the manufacture of transistors that can be used, for example, to make flexible, paper-thin computer screens.
