New 3D-printed artery can monitor blockages from the inside
When surgeons replace part of a blood vessel to treat blood clots, coronary disease, stroke damage and more, between 40% and 50% of those grafts fail. In response, UW engineers are developing an artificial vessel that can be monitored remotely.
Nanoparticles improve tumor treatment in mice
In mouse models of human lung cancer, the improved drug inhibited tumor growth more effectively than the standard drug. “Ultimately, our goal is to get this into human beings,” says pharmacy professor Glen Kwon.
New technique could slash energy use in making silicon
A chemistry professor has come up with a more sustainable way to make silicon at much lower temperatures for the kind of advanced batteries used in electronics such as phones, cameras and laptop computers.
Thin photodetector could increase performance without adding bulk
The advance could reduce the size and weight of a series of solar panels, produce a higher-quality photo in low lighting conditions, or even transmit data more quickly.
Old bones lead to new strategy for drug delivery
An engineering team has developed a new way to seed biomedical devices with agents that promote tissue growth and healing.
UW getting electron beam lithography system for nanotech research
Researchers from four UW campuses around the state will benefit from the new system, which uses a specialized technique for creating patterns 5,000 times smaller than the width of a human hair.
Advanced nano-cutter boosts emerging materials research at UW–Madison
The unique machine, the first of its kind in North America, is capable of milling in three dimensions with nanometer precision.
New computer chip manufacturing method squeezes more onto limited wafer space
Computer chip makers continuously strive to pack more transistors in less space, yet as the size of those transistors approaches the atomic scale, there are physical limits on how small they are able to make the patterns for the circuitry.

Discovery in growing graphene nanoribbons could enable faster, more efficient electronics
Graphene, an atom-thick material with extraordinary properties, is a promising candidate for the next generation of dramatically faster, more energy-efficient electronics. However, scientists have struggled to fabricate the material into ultra-narrow strips, called nanoribbons, that could enable the use of graphene in high-performance semiconductor electronics.
A new kind of wood chip: collaboration could lead to biodegradable computer chips
In an effort to alleviate the environmental burden of electronic devices, a team of University of Wisconsin–Madison researchers has collaborated with researchers in the Madison-based U.S. Department of Agriculture Forest Products Laboratory (FPL) to develop a surprising solution: a semiconductor chip made almost entirely of wood.
Solution-grown nanowires make the best lasers
Take a material that is a focus of interest in the quest for advanced solar cells. Discover a "freshman chemistry level" technique for growing that material into high-efficiency, ultra-small lasers. The result, disclosed today [Monday, April 13] in Nature Materials, is a shortcut to lasers that are extremely efficient and able to create many colors of light.
