the development of a new electron
0:12
microscope marks a Monumental
0:14
breakthrough in the field of microscopy
0:16
called the adom microscope this device
0:19
can capture the movement of electrons in
0:21
real time achieving temporal resolution
0:24
at the adoc second scale 1 quintillionth
0:30
traditional electron microscopes have
0:32
allowed scientists to observe the
0:34
smallest structures in the physical
0:36
world by using beams of electrons
0:38
instead of electromagnetic waves these
0:41
microscopes capture images based on the
0:43
interactions between the electrons and
0:45
the sample but until now their speed was
0:48
not sufficient to capture the rapid
0:50
movements of subatomic particles like
0:52
electrons previous ultrafast electron
0:55
microscopes use laser pulses to emit
0:57
electrons at speeds of a few atos
1:00
seconds creating a series of images like
1:02
frames in a movie however this still
1:05
left gaps in capturing the full range of
1:08
electron Dynamics the atom microscope
1:10
changes this by using a single aosc
1:13
electron pulse effectively freezing the
1:15
motion of electrons and providing a
1:22
interactions the atom microscope is
1:24
divided into two main sections the top
1:27
section generates an UltraViolet pulse
1:29
that that releases Ultra fast electrons
1:32
inside the microscope meanwhile the
1:34
bottom section utilizes two additional
1:36
laser pulses to gate initiate and
1:39
precisely control the movement of
1:41
electrons within the sample this
1:43
Innovative setup uses a technique
1:44
involving three pulses two em pulses and
1:48
an electron pulse the first em pulse
1:51
known as the pump pulse injects energy
1:53
into the sample causing the electrons to
1:55
move the second em pulse called the
1:58
gating pulse creates a brief window or
2:01
gate during which the electron
2:03
pulse is fired at the sample capturing
2:06
the ultra fast processes at play this
2:08
synchronization allows scientists to
2:10
observe the behavior of electrons with
2:17
Precision this transmission electron
2:19
microscope is like a very powerful
2:21
camera in the latest version of
2:23
smartphones says Muhammad Hassen
2:26
associate professor of physics and
2:28
Optical Sciences with this microscope we
2:31
hope the scientific Community can
2:33
understand the quantum physics behind
2:35
how electron behave and how electrons
2:40
move by allowing scientists to observe
2:43
electrons at atoc speeds this new
2:46
microscope opens the door to significant
2:48
advancements across multiple scientific
2:51
disciplines understanding the quantum
2:53
behavior of electrons can lead to new
2:55
discoveries in physics chemistry
2:58
bioengineering material science and more
3:01
this breakthrough may also pave the way
3:03
for real world applications of aosc
