To 6G and beyond: Engineers unlock the next generation of wireless communications

In the early 2010s, LightSquared, a multibillion-dollar startup promising to revolutionize cellular communications, declared bankruptcy. The company couldn’t figure out how to prevent its signals from interfering with those of GPS systems. Now, Penn Engineers have developed a new tool that could prevent such problems from ever happening again: an adjustable filter that can successfully […]

Extending the lifespan of lithium-metal batteries using a fluorinated ether diluent

The design of battery technologies with increasingly longer lifespans could help to meet the growing needs of the electronics and automotive industry. Lithium (Li) batteries are the most widely used rechargeable batteries worldwide. Thus, devising strategies that can increase their longevity could be far easier than designing entirely new batteries. Li-metal batteries, batteries with a […]

New technology keeps food refrigerated with phase change materials, reduces carbon emissions by 30%

A technology developed by Oak Ridge National Laboratory works to keep food refrigerated with phase change materials, or PCMs, while reducing carbon emissions by 30%. More than 100 million household refrigerators in operation across the United States consume up to 2 kilowatts of electricity daily. These refrigerators contribute to energy consumption and carbon emissions by […]
