Many companies have recognized an untapped opportunity for improving their development process: the requirements traceability matrix. Rather than wait until the end of the development cycle, the team builds the trace matrix when requirements first go under design control, and maintains it all the way through the submission process.
Exposed on a vertical face, rock climbers rely on their instincts and experience just as much as their equipment for survival. Depending on the climb, an assortment of gear is used for a successful ascension to the top—carabineers, cams, harnesses, specialized climbing shoes. Different styles of footwear are used for finessing cracks, balancing on small toeholds or smearing sloping slabs, the choice depends on individual preference.
Working on the cutting edge of a newly emerging area of solar-cell research, Univ. of California, Los Angeles engineers have invented a new process for manufacturing highly efficient photovoltaic materials that shows promise for low-cost industrial production. The new process uses so-called perovskite materials, which in the past few years have significantly advanced scientists' efforts to create the next generation of solar cells.
In a world’s first, researchers at the National Institute of Materials Science in Japan have succeeded in controlling the length of a one-dimensional, or supramolecular, assembly of molecules. Their method involves molecular self-organization, which until now has not been practical for polymer synthesis because of a lack of knowledge about the interplay of organizational pathways.
Local Motors Inc. and Oak Ridge National Laboratory have signed a new partnership to develop and deliver technology to produce the world’s first production 3-D printed vehicle. The CRADA between Local Motors and ORNL will explore making vehicle construction more efficient, including lower production time, costs and part count, coupled with higher standards of control, safety, aesthetics and mechanical flexibility.
Researchers from two continents have engineered an efficient and environmentally friendly catalyst for the production of molecular hydrogen (H2), a compound used extensively in modern industry to manufacture fertilizer and refine crude oil into gasoline. The new method can product industrial quantities of hydrogen without emitting carbon into the atmosphere.
Soil scientists at Abertay Univ. are using 3-D printing technology to find out, for the very first time, exactly what is going on in the world beneath our feet. In the same way that ecologists study the interactions of living organisms above ground, Prof.Wilfred Otten and researchers at the university’s SIMBIOS Centre are taking advantage of the new technology to do the same below ground.
A new fabrication method inspired by blown sugar art has been used to make structure in which an ultrathin graphene layer, or layers, is glued to a 3-D strutted framework. The researchers in Japan, calling this the “chemical blowing method”, overcomes the weak intersheet connections that have made this type of structure so difficult to create in the past.
Researchers have developed a simple, effective and relatively inexpensive technique for removing lignin from the plant material used to make biofuels, which may drive down the cost of biofuel production. Lignin, nature’s way of protecting plant cell walls, is difficult to break down or remove from biomass. However, that lignin needs to be extracted in order to reach the energy-rich cellulose that is used to make biofuels.
A group of researchers from the U.K. have used inkjet printing technology to successfully print cells taken from the eye for the very first time. The breakthrough, detailed in Biofabrication, could lead to the production of artificial tissue grafts made from the variety of cells found in the human retina and may aid in the search to cure blindness.
From green electricity tariffs to car sharing schemes, many sustainable products and services are being brought to market by start-ups. However, there has been relatively little research into how and why individuals take this step and whether their start-ups become a success. Fourteen European institutes coordinated by the Technical Univ. of Munich will be investigating this trend to see what potential it holds for a sustainable economy.
While business operations have matured to help better commercialize new products, an important puzzle piece is missing. Companies must fill this gap to complete the big picture and accelerate innovation. That missing piece is science. Over the past few decades, process manufacturing industries adapted business operations to effectively manage transformational changes.
Researchers at Oak Ridge National Laboratory are working with aircraft makers to determine energy savings through the use of additive manufacturing, also known as 3-D printing. The research team is printing airplane parts to show additive manufacturing’s potential as a technology that should be considered foundational to processes seeking more energy efficiency.
Yale Univ. neuroscientist Gordon Shepherd has studied neurons for decades. But until recently he’d never had a neuron he could grasp with his own two hands: Neurons are much too small. Now he’s got his very own 3-D neuron in all its spidery glory, a vastly enlarged but precise replica that is the latest custom-made anatomical model to emerge from the Yale Center for Engineering Innovation and Design (CEID).
Researchers at the Univ. of Colorado Boulder have successfully added a fourth dimension to their printing technology, opening up exciting possibilities for the creation and use of adaptive, composite materials in manufacturing, packaging and biomedical applications. The researchers incorporated “shape memory” polymer fibers into the composite materials used in traditional 3-D printing.
Researchers from North Carolina State Univ., the Univ. of North Carolina at Chapel Hill and Laser Zentrum Hannover have discovered that a naturally occurring compound can be incorporated into 3-D printing processes to create medical implants out of non-toxic polymers. The compound is riboflavin, which is better known as vitamin B2.
3-D printing isn’t just cheaper, it’s also greener, says Joshua Pearce, a Michigan Technological Univ. assoc. prof. of materials science and engineering/electrical and computer engineering. Even Pearce, an aficionado of the make-it-yourself-and-save technology, was surprised at his study’s results. It showed that 3-D printer use less energy and release less carbon dioxide than producing stuff in a factory and shipping it to a warehouse.
With a $855,000 grant from the U.S. Army Research Office, a trio of university researchers is proposing the development a new printing technology that adds a fourth dimension. By manipulating materials at the micro- and nanoscale dimensions, they hope to develop printable structures that can exhibit behavior that changes over time.
The U.S. economy retains myriad sources of innovative capacity; but not enough of the innovations occurring in America today reach the marketplace, according to a major two-year Massachusetts Institute of Technology study. The report found that potentially valuable innovations occur throughout the advanced manufacturing sector and in companies of all sizes, from multinational conglomerates to specialized “Main Street” firms.
Univ. of Illinois at Urbana-Champaign researchers have developed arrays of tiny nanoantennas that can enable sensing of molecules that resonate in the infrared (IR) spectrum. Other nanoscale antenna systems can't be tuned to a longer light wavelength due to limitations of traditional nanoantenna materials. The team used highly doped semiconductors, grown by molecular beam epitaxy.
Purdue Univ. researchers are working with the U.S. Army Research Laboratory to develop a technology for creating parts out of interlocking segments produced using 3-D printing to repair vehicles and other equipment in the field. The Purdue portion of the research focuses on clever, Lego-like building blocks called "topologically interlocking structures”.
Though nanosatellites already borrow several components, including cameras and radios, from terrestrial gadgets, propulsion systems have to be built from scratch. Researchers are working on electrospray ionic liquid “rockets”, but the microscopic needles they require are difficult and tedious to make. A researcher has found a way to let nature do the work, simplifying the fabrication process.
For the first time, Ford is making its Fusion sedan in the U.S. The company's Flat Rock, Michigan, plant began making the Fusion on Thursday. The plant, which is about 25 miles (40 km) south of Detroit, made the Ford Mustang sports car before getting a second shift of 1,400 workers to make the Fusion. The plant now has 3,100 workers.
The largest 3-D printed rocket engine component NASA hsa ever tested blazed to life Thursday, Aug. 22 during an engine firing that generated a record 20,000 pounds of thrust. This test is a milestone for one of many important advances the agency is making to reduce the cost of space hardware.
The world’s most famous painting has now been created on the world’s smallest canvas. Researchers at the Georgia Institute of Technology have “painted” the Mona Lisa on a substrate surface approximately 30 micrometers in width—or one-third the width of a human hair. The team’s creation, the “Mini Lisa,” demonstrates a technique that could potentially be used to achieve nanomanufacturing of devices.
