(Press-News.org) An Oak Ridge National Laboratory-developed advanced manufacturing technology, AMCM, was recently licensed by Orbital Composites and enables the rapid production of composite-based components, which could accelerate the decarbonization of vehicles, airplanes and drones.
Additive manufacturing compression molding, or AMCM, uses short-fiber-filled polymer and continuous fiber to print directly onto a mold with precise orientation to make parts such as propeller blades or battery boxes.
Compression molding then turns the print into an accurate finished piece. ORNL researchers proved AMCM significantly reduces time and cost by producing 100 parts in five hours, with each piece taking less than three minutes to print.
“By combining the fiber control of additive with the low porosity of compression molding, we can enable the high-volume production of next-generation composites,” ORNL’s Vipin Kumar said. “The mobility and aerospace industries need these lightweight materials to improve the energy efficiency of their applications.”
ORNL collaborated with Orbital to develop AMCM on a robotic system. Additional collaborators included IACMI — The Composites Institute.
UT-Battelle manages ORNL for DOE’s Office of Science, the single largest supporter of basic research in the physical sciences in the United States. DOE’s Office of Science is working to address some of the most pressing challenges of our time. For more information, visit energy.gov/science.

Scientists find link between photosynthesis and ‘fifth state of matter’
2023-05-03
Inside a lab, scientists marvel at a strange state that forms when they cool down atoms to nearly absolute zero. Outside their window, trees gather sunlight and turn them into new leaves. The two seem unrelated—but a new study from the University of Chicago suggests that these processes aren’t so different as they might appear on the surface.
The study, published in PRX Energy on April 28, found links at the atomic level between photosynthesis and exciton condensates—a strange state of physics that allows energy to flow frictionlessly ...
Researchers detect and classify multiple objects without images
2023-05-03
WASHINGTON — Researchers have developed a new high-speed way to detect the location, size and category of multiple objects without acquiring images or requiring complex scene reconstruction. Because the new approach greatly decreases the computing power necessary for object detection, it could be useful for identifying hazards while driving.
“Our technique is based on a single-pixel detector, which enables efficient and robust multi-object detection directly from a small number of 2D measurements,” said research team leader Liheng Bian from the Beijing Institute ...
Study provides genetic evidence on new osteoporosis drug heart attack risk
2023-05-03
New research highlights potential safety concerns around women taking romosozumab, a new anti-osteoporosis drug available on the NHS. The University of Bristol-led study, published in Arthritis & Rheumatology, analysed genetic data on nearly 34,000 people.
Despite romosozumab being particularly effective at reducing the risk of fracture in women with severe osteoporosis, potential safety concerns following trial data suggest the drug may cause an increased risk of heart attack. However, subsequent research has produced conflicting results.
An international team, led by Bristol Medical School researchers, sought to investigate whether, ...
OSU research shows how hackers can target smart meters to destabilize electricity grid
2023-05-03
CORVALLIS, Ore. – A power transmission grid can be destabilized by hackers who manipulate smart meters to create an oscillation in electricity demand, researchers in the Oregon State University College of Engineering have shown.
Findings were published in IEEE Access.
The study is important because understanding where a grid’s vulnerabilities lie and what they look like is the first step in designing protection mechanisms, says associate professor of electrical engineering and computer science Eduardo Cotilla-Sanchez, who led the project with graduate student Falah Alanazi.

New catalyst transforms carbon dioxide into sustainable byproduct
2023-05-03
The need to capture CO2 and transport it for permanent storage or conversion into valued end uses is a national priority recently identified in the Bipartisan Infrastructure Law to move toward net-zero greenhouse gas emissions by 2050.
Now, Northwestern University researchers have worked with an international team of collaborators to create acetic acid out of carbon monoxide derived from captured carbon. The innovation, which uses a novel catalyst created in the lab of professor Ted Sargent, could spur new interest in carbon capture and storage.
“Carbon capture is feasible today from a technical point of view, but not yet from an economic point ...
Virtual consulting can significantly cut carbon footprint in health care, new study suggests
2023-05-03
Virtual consulting is a new and emerging contributor to environmentally sustainable health care, according to findings of new research published in the Journal of Medical Internet Research.
The COVID-19 pandemic has accelerated the shift to virtual consulting, leading to its growing use. As health systems across the world strive to achieve net-zero carbon emissions, a critical question arises: what is the impact of virtual consulting on environmental sustainability in health care? A new research study led by Sara Shaw and team aims to address this ...
USC Verdugo Hills Hospital nationally recognized with first ‘A’ hospital safety grade
2023-05-03
LOS ANGELES — For the first time, USC Verdugo Hills Hospital (USC-VHH) earned an “A” Hospital Safety Grade from The Leapfrog Group, an independent national watchdog organization, for achieving the highest national standards in patient safety. This achievement places USC-VHH among top tier hospitals in the nation for safety and quality.
“Our entire staff is dedicated to improving and upholding the highest standards of patient care,” said Mary Virgallito, MSN, RN, chief quality officer at USC-VHH. “This score reinforces our ...
In a first, astronomers spot a star swallowing a planet
2023-05-03
As a star runs out of fuel, it will billow out to a million times its original size, engulfing any matter — and planets — in its wake. Scientists have observed hints of stars just before, and shortly after, the act of consuming entire planets, but they have never caught one in the act until now.
In a study that will appear in Nature, scientists at MIT, Harvard University, Caltech, and elsewhere report that they have observed a star swallowing a planet, for the first time.

Traces from the past
2023-05-03
Artefacts made of stone, bones or teeth provide important insights into the subsistence strategies of early humans, their behavior and culture. However, until now it has been difficult to attribute these artefacts to specific individuals, since burials and grave goods were very rare in the Palaeolithic. This has limited the possibilities of drawing conclusions about, for example, division of labor or the social roles of individuals during this period.
In order to directly link cultural objects to specific individuals and thus gain deeper insights into Paleolithic ...
New tusk-analysis techniques reveal surging testosterone in male woolly mammoths
2023-05-03
Graphics // Video
Traces of sex hormones extracted from a woolly mammoth's tusk provide the first direct evidence that adult males experienced musth, a testosterone-driven episode of heightened aggression against rival males, according to a new University of Michigan-led study.
In male elephants, elevated testosterone during musth was previously recognized from blood and urine tests. Musth battles in extinct relatives of modern elephants have been inferred from skeletal injuries, broken tusk tips and other indirect lines of evidence.
But the new study, scheduled ...
