«This finding could change the way we look at phase transformations within the cathode and the resulting loss of capacity in this class of material,» said Alpesh Khushalchand Shukla, a scientist at Berkeley Lab's Molecular Foundry, and lead author of the study.

Each compound, Sutterlin says, naturally melts or solidifies at a different specific temperature and can be used as the base material for an application, depending on the phase change point needed.

The technique, a new development — different from Zewail's Nobel Prize - winning work in femtochemistry, the visual study of chemical processes occurring at femtosecond scales — allowed researchers to observe directly the transitioning atomic configuration of a prototypical phase - change material, germanium telluride (GeTe), when it is hit by a femtosecond laser pulse.

At a certain level of phase change, the material's conductance suddenly jumps, and the device fires like a neuron.

In their proof - of - principle experiment, the researchers used germanium antimony telluride (GST)-- the kind of phase - change material found in CDs and DVDs — to make an improved switchable metasurface that can block or transmit particular wavelengths of light at the command of light pulses.

At that time, there were major advances in Building Sector technologies — in glazing materials (heat mirror and low - e coatings), passive and active solar energy systems design and applications, passive and active cooling applications, natural ventilation systems, phase - change materials, moveable insulation, building simulation modeling programs, daylighting systems and controls, energy management systems, night set - back thermostats and occupancy sensors, solar hot water heating, solar thermal electric generation and storage, photovoltaics and advances in low - energy lighting systems, to name just a few.
