New research shows a frictionless state can be achieved at macroscale
2024-07-15
(Press-News.org) UTICA, NY – The president of SUNY Polytechnic Institute (SUNY Poly), Dr. Winston “Wole” Soboyejo, and postdoctoral researcher, Dr. Tabiri Kwayie Asumadu, have published a revolutionary new paper titled, "Robust Macroscale Superlubricity on Carbon-Coated Metallic Surfaces." This paper explores an innovative approach to reducing friction on metallic surfaces – a significant advancement that could have major real-world impacts.

The study shows that superlubricity – a state with virtually no friction that was once believed to only be achievable at nanoscale – can now be maintained at macroscale for extended time periods under regular atmospheric conditions by employing sustainably produced carbon coatings made from biowaste.

These findings are significant for a number of practical reasons. In the automotive industry, more than 30 percent of fuel in passenger vehicles is used to overcome friction, so these novel coatings can help to drastically improve fuel efficiency. In manufacturing and industrial machinery, they could help to reduce wear and tear, leading to massive cost savings and decreasing the 1-4% of countries’ GDP that is spent on friction-related equipment issues. In electronic devices, friction at a minute scale can present large-scale challenges that coatings could help to alleviate.  

“This research truly could touch most industries,” said Dr. Asumadu. “From biomedical to energy sectors to nearly every kind of manufacturing, this approach could help to extend the life of machine parts, reduce maintenance and replacement costs, and create a more sustainable industrial future.”

The paper was published in Applied Materials Today by a group of eight materials scientists collaborating across Africa and the Northeastern United States, including Mobin Vandadi, Desmond Edem Primus Klenam, Kwadwo Mensah-Darkwa, Emmanuel Gikunoo, Samuel Kwofie, and Nima Rahbar.

“My colleagues and I are extremely proud of this work, particularly for the environmental and economic implications it could have,” said Dr. Soboyejo. “We look forward to seeing the breakthroughs in friction management technologies that will happen as researchers operationalize these approaches.”

This paper discusses experimental and computational results of ultralow (near-zero) friction of carbon-coated metallic depositions on substrates of structural steels, Ti, and Ni alloys. The macroscale superlubricity was demonstrated and sustained over several cycles through structurally misoriented carbon coatings on the metallic surfaces. Carbon nanocrystals with variants of graphene footprints were deposited on these metallic surfaces using a novel high temperature biowaste treatment process. The carbon nanocrystals deform, flatten, and coalesce in the wear tracks to form graphitic films leading to a superlubricious coefficient of friction of ~0.003. A coating life of ~150,000 cycles with reduced wear rates was obtained on Ni and steel substrates. The experiments were validated with atomistic simulations providing mechanistic insights into the effects of the graphene variants on the observed frictionless conditions. The underlying mechanisms of the coating/substrate interactions contributing to the macroscale superlubricity are elucidated. The implications of the current results are explored for designing robust and low-cost macroscale superlubricious carbon coatings on metallic substrates. Biowaste is a carbon source within a circular economy that uses material recycling to reduce the global carbon footprint.

A novel and unique neural signature for depression revealed

2024-07-15
HOUSTON - (July 15, 2024) -  As parents, teachers and pet owners can attest, rewards play a huge role in shaping behaviors in humans and animals. Rewards – whether as edible treats, gifts, words of appreciation or praise, fame or monetary benefits – act as positive reinforcement for the associated behavior. While this correlation between reward and future choice has been used as a well-established paradigm in neuroscience research for well over a century, not much is known about the neural process underlying it, namely how the brain encodes, ...

Academic psychiatry urged to collaborate with behavioral telehealth companies

2024-07-15
Waltham — July 15, 2024 — The strengths of academic psychiatry departments and the fast-growing private telehealth sector are complementary, according to a Perspective article published in Harvard Review of Psychiatry, part of the Lippincott portfolio from Wolters Kluwer. Justin A. Chen, MD, MPH, a psychiatrist at Weill Cornell Medicine in New York City, and colleagues reviewed literature on provision of outpatient mental health care in the United States. They concluded that academic psychiatry departments and telehealth companies could mutually benefit from strategic collaboration.  Academic medical centers struggle to ...

NASA’s Webb investigates eternal sunrises, sunsets on distant world

NASA’s Webb investigates eternal sunrises, sunsets on distant world
2024-07-15
Researchers using NASA’s James Webb Space Telescope have finally confirmed what models have previously predicted: An exoplanet has differences between its eternal morning and eternal evening atmosphere. WASP-39 b, a giant planet with a diameter 1.3 times greater than Jupiter, but similar mass to Saturn that orbits a star about 700 light-years away from Earth, is tidally locked to its parent star. This means it has a constant dayside and a constant nightside—one side of the planet is always exposed to its star, while the other is always shrouded in darkness. Using Webb’s NIRSpec (Near-Infrared ...

Receptors make dairy cows a prime target for influenza, ISU team finds

Receptors make dairy cows a prime target for influenza, ISU team finds
2024-07-15
AMES, Iowa – As highly pathogenic avian influenza has spread in dairy herds across the U.S., the virus is being detected in raw milk. A new study by a broad team of researchers at Iowa State University’s College of Veterinary Medicine helps explain why. Sialic acid, a sugar molecule found on the surface of some animal cells, acts as a receptor for influenza. Without sialic acid providing an entry point to attach, invade and infect, a flu virus is unlikely to find a potential host hospitable. Before the recent HPAI outbreak ...

A new neural network makes decisions like a human would

2024-07-15
Humans make nearly 35,000 decisions every day, from whether it’s safe to cross the road to what to have for lunch. Every decision involves weighing the options, remembering similar past scenarios, and feeling reasonably confident about the right choice. What may seem like a snap decision actually comes from gathering evidence from the surrounding environment. And often the same person makes different decisions in the same scenarios at different times. Neural networks do the opposite, making the same decisions each time. Now, Georgia Tech researchers in Associate Professor Dobromir Rahnev’s lab are ...

You're just a stick figure to this camera

2024-07-15
Images   A new camera could prevent companies from collecting embarrassing and identifiable photos and videos from devices like smart home cameras and robotic vacuums. It's called PrivacyLens and was made by University of Michigan engineers.   PrivacyLens uses both a standard video camera and a heat-sensing camera to spot people in images from their body temperature. The person's likeness is then completely replaced by a generic stick figure, whose movements mirror those of the person it stands in for. The accurately animated stick figure allows a device relying on the ...

2024-07-15
Astronomers have created the most detailed weather report so far for two distant worlds beyond our own solar system. The international study – the first of its kind – reveals the extreme atmospheric conditions on the celestial objects, which are swathed in swirling clouds of hot sand amid temperatures of 950C. Using NASA’s powerful James Webb Space Telescope (JWST), researchers set out to capture the weather on a pair of brown dwarfs – cosmic bodies that are bigger than planets but smaller than stars. These brown dwarfs, named collectively ...
