Ultrafast optical fiber-based electron gun to reveal atomic motions

[R]esearchers at the Max Planck Institute for the Structure and Dynamics of Matter are reporting "ultrabright" electron sources with sufficient brightness to literally light up atomic motions in real time—at a time scale of 100 femtoseconds, making these sources particularly relevant to chemistry because atomic motions occur in that window of time.

After seeing the first atomic movies of phase transitions in bulk thin films using high-energy (100 kilovolt) electron bunches, the researchers wondered if they could achieve atomic resolution of surface reactions—occurring within the first few monolayers of materials—to gain a better understanding of surface catalysis.

So they devised a low-energy (1-2 kilovolt) time-resolved electron diffraction concept of using fiber optics for miniaturization and the ability to stretch the electron pulse, then apply streak camera technology to potentially obtain subpicosecond temporal resolution—a difficult feat within the low-electron energy regime.

Of the myriad possible nuclear configurations, the group discovered that the system collapses to just a few key modes that direct chemistry and that a reduction in dimensionality that occurs in the transition state or barrier-crossing region can be inferred. "We see it directly with the first atomic movies of ring closing, electron transfer and bond breaking," said Miller.

I bet you’ll claim to understand this, too.

at a time scale of 100 femtoseconds,

Or how long it takes me to eat a foot long sub.

Let’s start a list of what you can do in one quadrillionth of a second.

1. Recognize a dem
2. Hate a dem

It would be cool to see how electrons move around the nucleus in real time.

Lately I’ve been fascinated about the inner workings of mammalian cells particularly motor proteins. they have to guess at how things work because they are smaller than the wave length of light and can not be directly observed. perhaps this is a work around.

Good!

It means that scientists are getting closer to discovering how phentosubnemicals interact with mirsoplenieas. That would change life as we know it.

It's impossible to know both an electron's speed and location, therefore we'll never be able to see how they move around the nucleus. :(

I understand that, because they are quantum in nature. However, I mean it in the sense of acquiring a better understanding through acquiring more information so patterns can be discerned and become explainable.

Y’all could be pulling all of these terms right out of your fannies and the rest of us will never know.

Some workings of this world may have to wait on the Creator to reveal, as our human capabilities for discernment seem lacking in the extreme, however interesting these workings may be.

Does this have anything to do with daylight savings time?

You’re still thinking about it like a moon orbiting a planet which isn’t the case. More like a fog with waves moving through it with certain places concentrated more or less at any given time.

Fascinating!
They might be able to image radioactive decay.

For sure this would be a great tool for Semiconductor research.
