K Technology currently builds
vibration
isolators to handle payloads from
3 lbs to 10,000 lbs (per isolator).

The
need for more precise vibration isolation with atomic
force microscopy is becoming more critical as resolutions
continue to bridge from micro to nano. When measuring
very few angstroms or nanometers of displacement,
an absolutely stable surface must be established for
the instrument

Excerpted
from Laboratory Equipment Magazine:
Expanding
capability, scanning range
Since the release of the first commercial AFM about
25 years ago, technology advances have been integrated
into AFMs to improve their performance. One of these
has been expanding the AFMs ability to image biological
samples in an aqueous buffer, and provide a range
of physical data for the sample-a key capability that
not all microscopy techniques can deliver. Another
has been to increase the imaging speed of AFMs. Unlike
SEMs, which are capable of scanning in near real-time,
conventional AFMs, prior to about five years ago,
required between one and 100 minutes to obtain a high-resolution
image. With the introduction of high-speed AFM systems,
imaging speeds can now be achieved that are three
orders A of magnitude of three times faster than with
previous AFMs.
Since the AFM was designed for imaging rnicro-structures
on the micrometer and nanometer scale, its single
scan image size is somewhat limited to a maximum scanning
area of about l00 x100 micrometers. When researchers
require a larger scale image, they typically use a
SEM, which can produce quality images on a wide range
of magnifications and sample sizes in the X and Y
axis. In one pass, the SEM can image an area on the
order of square millimeters, and with a depth of field
of millimeters.
Within the past several years, however, research into
AFM design, conducted by the Paul Hansma Research
Group, Department of Physics, at the Univ.. of California,
Santa Barbara, has demonstrated success with AFM imaging
of large-scale samples at nanoscale resolutions, while
extending the range of the Z-axis. The lab's current
technical challenge is to design an AFM system that
can significantly extend the scan range, while operating
at a reasonable imaging speed with acceptable image
resolution and linearity.
The Hansma lab's objective for expanding the scan
range of its latest prototype AFM design is directed
toward exploring the molecular origins of fracture
resistance in mineralized tissues, primarily bone.
Because of the limited range of AFMs, many critical
measurements of large-scale bone fractures have not
been produced. Typically, SEM is used to show the
entirety of a bone crack, but it is unable to provide
the detailed information that an AFM is capable of
producing, nor to image bone matrix material properties
in a natural hydrated fracture process.
Bone fracture and fracture surfaces on the microscale
and nanoscale have been imaged with AFM," says
Hansma.. "but many microfractures remain beyond
the reach of AFM, such as those created by bone diagnostic
instruments like the reference point indentation (RPI)
instrument."
The RPI is an instrument that creates a small indent
in the bone to determine its fracture resistance and
gathers data on the depth and forces of the indent.
"By imaging these indents and the associated
rnicrofractures, we have an opportunity to make real
progress in understanding the nanoscale mechanisms
that contribute to fracture resistance," explained
Hansma.

Future
Product: Minus K's is designing a new Small
and Mighty isolator |
|
|
|
The
LC-4 is a highly compact designed, low-frequency
negative-stiffness isolator. While we haven't
finalized the dimensions yet we are looking
approximately 5" W x 4" D x 6.5"
H (127mm W x 114mm D x 152mm H).
Payload capacites will be up to 150 lbs
(68 kg) for this small and mighty isolator.
Planned
performance characteristics:
- Horizontal
frequencies are weight dependent.
- Horizontal
frequency of 0.5 Hz is achieved at the
upper limit of the payload range.
- Vertical
frequency is tunable to 0.5 Hz throughout
the payload range.
As
with all Minus K isolators, they are completely
passive and use no air or electricity. The
isolators can be combined into multi isolator
systems to support heavy payloads while
taking up very little room themselves.
If
needed, the LC-4 isolators can be customized
to achieve user specific needs. Eg., different
horizontal and vertical frequencies, damping,
etc. They can also be made cleanroom and
vacuum. compatible.

Any college/university within the United
States, that have an AFM, Electron Microscope, Interferometer,
Laser Optical System, Micro Hardness Tester, or any
other special equipment that would benefit from a
low-frequency vibration isolator and apply.
No purchase necessary.
The submission
forms will be judged
by the 20 Year Giveaway Committee on multiple catagories.Limited
to one submission per college department.
Submission deadline for applications is January 31,
2014.
The selected
college departments will be notified by February 28,
2014 and posted on Minus K's website.
A new FREE Minus K vibration isolator will be shipped
within one month of notification.
Minus K will conduct
a brief interview with the selected departments six
months after receiving their isolator. The interviews
will be used to learn how vibration isolator helped
with the application goals and interview may be used
for articles in industry publications.
