CLEMSON, South Carolina By using laser spectroscopy in a photophysics experiment, Clemson University researchers have broken new ground that could result in faster and cheaper energy to power electronics.
This novel approach, using solution-processed perovskite, is intended to revolutionize a variety of everyday objects such as solar cells, LEDs, photodetectors for smart phones and computer chips. Solution-processed perovskite are the next generation materials for solar cell panels on rooftops, X-ray detectors for medical diagnosis, and LEDs for daily-life lighting.

If you were given ultrasound in a word association game, sound wave might easily come to mind. But in recent years, a new term has surfaced: bubbles. Those ephemeral, globular shapes are proving useful in improving medical imaging, disease detection and targeted drug delivery. There s just one glitch: bubbles fizzle out soon after injection into the bloodstream.
Now, after 10 years work, a multidisciplinary research team has built a better bubble. Their new formulations have resulted in nanoscale bubbles with customizable outer shells so small and durable that they can travel to and penetrate some of the most inaccessible areas in the human body.

Argonne is looking at alternative supply chains for critical materials, says Cynthia Jenks, head of Argonne s circular economy initiative. Mining these materials from our nation s urban sources would enhance national security.

Imagine 10 million people, each drinking a bottle of water a day and then deciding on what to do with the container. Do they throw it in the trash, toss it to the gutter or recycle it?
This isn t a far-fetched scenario. In fact, U.S. consumers purchased nearly 50 billion water bottles in 2018, or about 137 million bottles a day, according to one estimate.
Engineers created light-activated materials that execute precise movements and form complex shapes without the need for wires, motors or other energy sources. The research could lead to smart light-driven systems such as high-efficiency solar cells that automatically follow the sun s direction.

An interdisciplinary research team at Lehigh University has unraveled how functional biomaterials rely upon an interfacial protein layer to transmit signals to living cells concerning their adhesion, proliferation and overall development.
According to an article published today in
Scientific Reports, the nanoscale features and properties of an underlying substrate do not impact the biological response of cells directly. However, these properties indirectly influence cell behavior through their control over adsorbed proteins.
In the article, Nanostructure of bioactive glass affects bone cell attachment via protein restructuring upon adsorption, the Lehigh team demonstrates that living cells respond to interfacial layer characteristics that arise as a consequence of micro- and nano-scale structures engineered into a substrate material. These infinitesimally-tiny structures have an enormous impact upon the nature of the protei
