Observing a molecule stretch and bend in real-time

Being able to watch how molecules bend, stretch, break or transform during chemical reactions requires state-of-the-art instruments and techniques that can observe and track all the atoms within a molecule with high sub-atomic ...

Researchers provide new method to boost clean energy research

Electrochemical energy systems—processes by which electrical energy is converted to chemical energy—are at the heart of establishing more efficient generation and storage of intermittent energy from renewable sources ...

Using bacteria to protect roads from deicer deterioration

Tiny bacteria could soon be chipping in to keep roads from chipping away in the winter, according to Drexel University researchers who are looking into new ways to make our infrastructure more resilient.

The cost of computation

For decades, physicists have wrestled with understanding the thermodynamic cost of manipulating information, what we would now call computing. How much energy does it take, for example, to erase a single bit from a computer? ...

Tuneable reverse photochromes in the solid state

Photochromes are dyes that change their colour depending on the light they receive. When light is switched off they can either remain in their photoinduced state (P-type photochromes) or turn back to their original state ...
