Aug 16, 2021 (Nanowerk News) Vascular diseases such as aneurysms, peripheral artery disease and clots inside blood vessels account for 31% of global deaths. Despite this clinical burden, cardiovascular drug advancements have slowed over the past 20 years. The decrease in cardiovascular therapeutic development is attributed to the lack of...

‘Thermal switches’ made of graphene foam dynamically moderate heat of electronic devices
Aug 16, 2021 (Nanowerk News) Modern devices that use lithium ion batteries, like smartphones and electric cars, seem pretty robust. But try to use one in extreme heat or cold, and you'll see how susceptible they are to malfunctions and low performance due to temperature. Purdue University engineers have developed...
