iDirector interview with Bernd Kabius

I'm Allison Campbell and I'm here with Bernd Kabius he is the microscopy lead in
Guten Tag Bernad
So uh... you've been in EMSL for a couple years now can you just give us
a little bit about your background
and what attracted you to come to the facility?
It's close to two years now
and I started out as a materials scientist in Germany in a
university, some small university in Baravia.
Uh... after that I switched for more than ten years to physics.
So I worked in
a center for solid states physics uh... and they I more or less specialized in
TEM. Before that it was corrossion electrial chemistry.
So after that time I went with a project which we had
in this national lab I was working in phyics.
And that project was getting some instrument resolutions and I went
the project into industry to
the company which build it. So I stayed there for two
and my visit
was a little bit shorter than I
because I got the opportunity to go to the United
States at a national lab
this is how I got into the TEAM project that was a DOE funded
project uh...which lasted 6, 7, 8 years.
and got resolution down to a new record of over 5 sub-Ångstrom resolution
and that also brings to why I am here
uh... because I think that EMSL and PNNL
offers the best environments for these next projects. And these projects
in situ TEM
and the other major capibility gap is
I've often heard you say you know the last decade was a resolution in this
decade is
and in situ and looking at things and the next decade is taking in situ doing
dynamics with it.
Which leads me to one of our main projects that were uh... kicking off here
ultrafast TEM, which you are going to lead for us. Can you explain what ultrafast
TEM is and
why it's so important to the field?
So uh...
let me briefly start again with in situ ultrafast is part of in situ microscopy
and in TEM since the fifties we are
already looking at nano sized things
down to atom scale and at that scale
things simply happen fast.
So uh... speed of sound in our world that is 330 meter per second
in air and a few kilometer in solid state
forgive me depressed segment uh... india wan kim the few convicted solid-state
that translates to femtoseconds in the atomic world
right now
Femtoseconds that is 10 x -15 and our present time
resolution is 10 x -15, 10 x -1 or -2
for most experiments.
With one exception that is 10 x -9.
We are far from where we have to be in order to see things happening in real time.
So we already have in situ
that will help us already a lot.
For the coming decade of in situ
microscopy but we need to build up further
to get the speed of the processes
which we are looking for.
And for that extra we have two projects
so uh... One is S/TEM, dynamic TEM
which is already being assembled as we
speak of and we hope to get to
atomic resolution in micro-second speed.
and clarified this is debate opted by the uk if they'd be prepared
information from that experience
right you people to stop them
for quite a false
which would get us all to look back at the same
so it these are our director use everybody gets a chance to ask
questioner j_d_ harris question
i don't think the future of expound related to parliamentary cupid support
nestle we have the three science the incinerator gennady dat from that
uh... the reason that we have enhanced focus on biology is in response uh...
last year's review where they told us that we really needed to get that
science the more focused
and more integrated with the e_r_ biology so it may seem to staff that
we're going slowly towards biology but it's really just getting that team right
