Study finds emissions from widely used cookstoves vary with use

The smoke rising from a cookstove fills the air with the tantalizing aroma of dinner – and a cloud of pollutants and particles that threaten both health and the environment. How families in developing countries use their cookstoves has a big effect on emissions from those stoves, and laboratory emission tests don’t accurately reflect real-world … Read more

Nowhere to hide: New device sees bacteria behind the eardrum

Doctors can now get a peek behind the eardrum to better diagnose and treat chronic ear infections, thanks to a new medical imaging device invented by University of Illinois researchers. The device could usher in a new suite of non-invasive, 3-D diagnostic imaging tools for primary-care physicians. The research team, led by electrical and computer … Read more

First-ever demonstration of autonomous bird-like robot perching on a human hand

By the virtue of their size and speed, birds are uniquely capable of efficient flight while flapping their wings and while gliding. Researchers at the University of Illinois at Urbana-Champaign have duplicated the control functions that allow birds to successfully perform a soft landing—in this case, perching on a human hand. “We believe we have … Read more

Computing the best high-resolution 3-D tissue images

Real-time, 3-D microscopic tissue imaging could be a revolution for medical fields such as cancer diagnosis, minimally invasive surgery and ophthalmology. University of Illinois researchers have developed a technique to computationally correct for aberrations in optical tomography, bringing the future of medical imaging into focus. The computational technique could provide faster, less expensive and higher … Read more

Controlling heat flow with atomic-level precision

Through a combination of atomic-scale materials design and ultrafast measurements, researchers at the University of Illinois have revealed new insights about how heat flows across an interface between two materials. The researchers demonstrated that a single layer of atoms can disrupt or enhance heat flow across an interface. Their results are published this week in … Read more

Study: Optimizing biofuel supply chain is a competitive game

As biofuel production has increased – particularly ethanol derived from corn – a hotly contested competition for feedstock supplies has emerged between the agricultural grain markets and biofuel refineries. This competition has sparked concern for the more fundamental issue of allocating limited farmland resources, which has far-reaching implications for food security, energy security and environmental … Read more

Fabrication method proves value for bone scaffold design

Researchers at the University of Illinois have developed a new method for the fabrication of artificial bone scaffolds that can assess important pore design factors such as porosity and their role in new bone formation. Their method’s capabilities for in vivo control of different scale porosities could lead to more flexible, efficient design of bone … Read more

New quantitative microscopy method offers stain-free cancer detection

The century old process of staining biological tissue for examination under a microscope remains today as the standard assessment tool for pathologists looking for signs of cancer. Now a new stain-free imaging method for cancer diagnosis has been developed that provides images that rival or surpass those from histological staining. In addition, the technique is automated, and it provides quantitative data on structures at the cellular level.

Particle-free silver ink prints small, high-performance electronics

University of Illinois materials scientists have developed a new reactive silver ink for printing high-performance electronics on ubiquitous, low-cost materials such as flexible plastic, paper, or fabric substrates. Jennifer Lewis, the Hans Thurnauer Professor of Materials Science and Engineering, and graduate student S. Brett Walker described the new ink in the Journal of the American Chemical Society. “We are … Read more

Physicists localize 3-D matter waves for first time

An illustration of Anderson localization. The green balloons represent disordered barriers that localize the sound of the trumpet at its source.

University of Illinois physicists have experimentally demonstrated for the first time how three-dimensional conduction is affected by the defects that plague materials. Understanding these effects is important for many electronics applications. Led by physics professor Brian DeMarco, the researchers achieved complete localization of quantum matter waves in three dimensions, first theorized roughly half a century … Read more
