Rensselaer Polytechnic Institute (RPI) is a private research university in Troy, New York, with additional campuses in Hartford and Groton, Connecticut. It was established in 1824 by Stephen van Rensselaer and Amos Eaton for the "application of science to the common purposes of life" and is the oldest technological university in the English-speaking world. Numerous American colleges or departments of applied sciences were modeled after Rensselaer. Built on a hillside, RPI's 265-acre (107 ha) campus overlooks the city of Troy and the Hudson River and is a blend of traditional and modern architecture. The institute operates an on‑campus business incubator and the 1,250-acre (510 ha) Rensselaer Technology Park.

Transmitting Data From Space to Earth With Laser Filaments

“Pulsed light clears a path through the atmosphere for second beam of information Could light be used to transmit information between satellites and Earth? Atmospheric water vapor scatters and absorbs light energy, but overcome that obstacle, and light will carry …

Metal-Breathing Bacteria Could Transform Electronics, Biosensors, and More

“When the Shewanella oneidensis bacterium “breathes” in certain metal and sulfur compounds anaerobically, the way an aerobic organism would process oxygen, it produces materials that could be used to enhance electronics, electrochemical energy storage, and drug-delivery devices. The ability of …

Potassium Metal Battery Emerges as a Rival to Lithium-Ion Technology

“From cell phones, to solar power, to electric cars, humanity is increasingly dependent on batteries. As demand for safe, efficient, and powerful energy storage continues to rise, so too does the call for promising alternatives to rechargeable lithium-ion batteries, which …

Living Skin Can Now be 3D-Printed With Blood Vessels Included

“Development is significant step toward skin grafts that can be integrated into patient’s skin Researchers at Rensselaer Polytechnic Institute have developed a way to 3D print living skin, complete with blood vessels. The advancement, published online today in Tissue …

Semiconducting Material More Affected By Defects Than Previously Thought

“A promising semiconductor material could be improved if flaws previously thought irrelevant to performance are reduced, according to research published today in Nature Communications. A group of researchers at Rensselaer Polytechnic Institute and other universities has shown that a specific …

Manipulating Light-Matter Interaction Unlocks Properties for Quantum Information Storage and Computing

New Computer Model Predicts How Fracturing Metallic Glass Releases Energy at the Atomic Level

“Researchers developed a new computer model that shows how metallic glass behaves under stress to one day build better materials. Metallic glasses — alloys lacking the crystalline structure normally found in metals — are an exciting research target for tantalizing applications, including …

New Deposition Technique Puts the Heat on Silicon

“In the early history of electronic devices, germanium, a more efficient elemental semiconductor than silicon, was the material of choice. Ultimately, the high cost of developing germanium crystals eclipsed its efficiency, and silicon captured the field. But new research establishing …

Tungsten Offers Nano-Interconnects a Path of Least Resistance

“As microchips become ever smaller and therefore faster, the shrinking size of their copper interconnects leads to increased electrical resistivity at the nanoscale. Finding a solution to this impending technical bottleneck is a major problem for the semiconductor industry. One …
