Grasshopper wing structure inspires design of gliding robot wings
CHAMPAIGN, Ill. — A collaboration between Princeton University engineers and entomologists at the University of Illinois Urbana-Champaign began with the researchers chasing grasshoppers in a hot parking lot. Their eventual focus on the hindwings of one species of grasshopper, Schistocerca americana, the American grasshopper, is inspiring a new approach to untethered gliding flight. The scientists […]
New computer simulation could light the way to safer cannabinoid-based pharmaceuticals
New psychoactive substances, originally developed as potential analgesics but abandoned due to adverse side effects, may still have pharmaceutical value if researchers could nail down the causes of those side effects. A new study from the University of Illinois Urbana-Champaign used deep learning and large-scale computer simulations to identify structural differences in synthetic cannabinoid molecules that cause them to bind to human brain receptors differently from classical cannabinoids.
Study finds that tweaked synthetic polymers boost conductivity
A new study marks a significant step forward in positioning synthetic polymers as an alternative for expensive, unsustainable minerals used in the manufacture of devices such as conductors, transistors and diodes.
Study shows new hope for commercially attractive lithium extraction from spent batteries
A new study shows that lithium — a critical element used in rechargeable batteries and susceptible to supply chain disruption — can be recovered from battery waste using an electrochemically driven recovery process. The method has been tested on commonly used types of lithium-containing batteries and demonstrates economic viability with the potential to simplify operations, minimize costs and increase the sustainability and attractiveness of the recovery process for commercial use.
Atom-scale stencil patterns help nanoparticles take new shapes and learn new tricks
CHAMPAIGN, Ill. — Inspired by an artist’s stencils, researchers have developed atomic-level precision patterning on nanoparticle surfaces, allowing them to “paint” gold nanoparticles with polymers to give them an array of new shapes and functions. The “patchy nanoparticles” developed by University of Illinois Urbana-Champaign researchers and collaborators at the University of Michigan and Penn State […]
How will the government shutdown impact air travel?
Although Transportation Security Administration officers and air traffic controllers are considered essential workers, any reduction in staff could result in long security lines and flight delays or cancellations, says University of Illinois Urbana-Champaign aviation security expert Sheldon H. Jacobson.
Model tackles key obstacle to efficient plastic recycling
CHAMPAIGN, Ill. — Most people who separate their plastic waste for recycling assume the bulk of it will in fact be recycled. But current recycling methods, which “require sorting, grinding, cleaning, remelting and extrusion to obtain plastic pellets, usually lead to lower value materials because of contamination and mechanochemical degradation,” the authors of a new […]
New MRI approach maps brain metabolism, revealing disease signatures
CHAMPAIGN, Ill. — A new technology that uses clinical MRI machines to image metabolic activity in the brain could give researchers and clinicians unique insight into brain function and disease, researchers at the University of Illinois Urbana-Champaign report. The non-invasive, high-resolution metabolic imaging of the whole brain revealed differences in metabolic activity and neurotransmitter levels […]
Researchers capture nanoparticle movements to forge new materials
Researchers can now observe the phonon dynamics and wave propagation in self-assembly of nanomaterials with unusual properties that rarely exist in nature. This advance will enable researchers to incorporate desired mechanical properties into reconfigurable, solution-processible metamaterials, which have wide-ranging applications — from shock absorption to devices that guide acoustic and optical energy in high-powered computer applications.
Study finds that individual layers of synthetic materials can collaborate for greater impact
Millions of years of evolution have enabled some marine animals to grow complex protective shells composed of multiple layers that work together to dissipate physical stress. In a new study, engineers have found a way to mimic the behavior of this type of layered material, such as seashell nacre, by programming individual layers of synthetic material to work collaboratively under stress. The new material design is poised to enhance energy-absorbing systems such as wearable bandages and car bumpers with multistage responses that adapt to collision severity.
New approach makes AI adaptable for computer vision in crop breeding
CHAMPAIGN, Ill. — Scientists developed a machine-learning tool that can teach itself, with minimal external guidance, to differentiate between aerial images of flowering and nonflowering grasses — an advance that will greatly increase the pace of agricultural field research, they say. The work was conducted using images of thousands of varieties of Miscanthus grasses, each […]
DNA origami guides new possibilities in the fight against pancreatic cancer
One of the challenges of fighting pancreatic cancer is finding ways to penetrate the organ’s dense tissue to define the margins between malignant and normal tissue. A new study uses DNA origami structures to selectively deliver fluorescent imaging agents to pancreatic cancer cells without affecting normal cells. The study, led by University of Illinois Urbana-Champaign mechanical science and engineering professor Bumsoo Han and professor Jong Hyun Choi at Purdue University, found that specially engineered DNA origami structures carrying imaging dye packets can specifically target human KRAS mutant cancer cells, which are present in 95% of pancreatic cancer cases.
