9.17 New Process for Making MXEnes Via Vapor-Phase Synthesis Could Expand Its Technological Applications MXenes are two-dimensional nanomaterials first synthesized at Drexel University in 2011. They have been recognized by the International Union of Pure and Applied Chemistry as an emerging technology with “true potential to transform our world.” But their widespread use has thus far been limited by the complicated process it takes to produce them. In a recent paper, researchers from Drexel, with collaborators at the University of Pennsylvania and Murata Manufacturing Co., Ltd., show that a process called chemical vapor deposition can be tailored to produce the nanomaterials in a form, quality and quantity — and potentially at a lower cost — that could one day allow them to be used in electronic, environmental and quantum technologies.
8.18 For Green Building, 'Durable Is the New 'Sustainable' Reducing the negative environmental impact of buildings — globally one of largest contributors to greenhouse gas — might be even more difficult than expected. New research from Drexel University indicates that, due to the steady increase in damaging extreme weather events each year, designers must begin to consider not if, but how long, their buildings will be rendered inoperable — and how the resources to get it back online will contribute to its overall environmental impact.
7.28 Soft, Sticky, Stretchable Biosensors Make a Better Connection Biosensors have revolutionized home healthcare over the last two decades. Devices like wearable heart rate and blood glucose monitors are giving people with chronic health conditions the information and assurance they need to maintain an active lifestyle. But even the best sensors are limited by their ability to sustain skin contact through the rigors of physical activity. Researchers from Drexel University and Penn State University took on the challenge of improving the hydrogel material used in biosensors. And, in recently published research, they reported a new formula for making the gelatinous substrate that is versatile, durable and adhesive enough to make a stronger connection.
