Teckneters,
There are a couple of articles that I thought you might find useful /interesting regarding epoxy's and tapes.
See below....

Solve Your Measurement Needs With the NI C Series Platform
National Instruments C Series platform consists of more than 50 modules
available for different measurements including: thermocouple, voltage,
strain, and digital accelerometers to name a few. C Series modules combine
signal conditioning, connectivity, and data acquisition into a small module
for each specific measurement type.

NANOSCALE LASERS
Researchers at Arizona State University and the Technical University of
Eindhoven in the Netherlands are looking to shrink lasers to the nanoscale
level, opening up the possibility of significantly improving the performance
of computers and speeding up Internet access. By making the lasers smaller,
engineers would enable the devices to be more effectively integrated with
small electronics components.
The size of lasers in any one dimension has been thought to be limited to
one-half of the wavelength involved. For instance, for lasers used in
optical communications the required wavelength is about 1,500 nanometers,
so a 750-nanometer laser was thought to be the smallest a laser could be
made for optical communications. To overcome this limitation, researchers
at ASU and Eindhoven are using approaches such as combining semiconductors
and metals such as gold and silver, according to Cun-Zheng Ning, a
professor at ASU's School of Electrical, Computer and Energy Engineering.
"It turns out that the electrons excited in metals can help you confine a
light in a laser to sizes smaller than that required by the diffraction
limit," Ning explains. "Eventually, we were able to make a laser as thin
as about one quarter of the wavelength or smaller, as opposed to one half."
Ning and professor Martin Hill, leader of the Eindhoven research team, have
demonstrated that such a semiconductor/dielectric layer, thinner than the
diffraction limit and squeezed between metal layers, can emit laser light
at low temperature. They are working to achieve similar results at room
temperature.

TECHS OF THE WEEK
A micro-reinforcement technology enables new applications where existing
thermoplastics, elastomers, thermosets, and reinforcing technologies have
not had sufficient toughness or fracture strength, particularly at elevated
temperatures, or the ability to endure flexure for millions of cycles
without severe particulation. The technology can be used for elastomers as
well as for polymers. The resulting composite is available in sheet
precursor form, which can then be converted into different molded
shapes. http://link.abpi.net/l.php?20090804A4
A technology allows the authentication of objects such as banknotes,
paycards, passports, and identity cards by the presence of a specific type
of phosphor. The phosphor type is identified by a non-destructive repeatable
procedure, based on the stimulated emission of light by the phosphor when
irradiated with radiation of the proper wavelength.

TECH BRIEFS
A method to encode and read numbers incorporates some features of
conventional optical bar coding and radio-frequency identification (RFID)
tagging, but overcomes some of the disadvantages of both:(1) Unlike optical
bar coding, numbers can be read without having a line of sight to a tag;
and (2) the tag circuitry is simpler than the circuitry used in
conventional RFID. http://link.abpi.net/l.php?20090804A11

Adhesive tapes, the adhesive resins of which can be cured by exposure to
ultraviolet and/or visible light, are being developed as repair patch
materials. The tapes, including their resin components, consist entirely of
solid, low-out-gassing, nonhazardous or minimally hazardous materials. They
can be used in air or in vacuum and can be cured rapidly, even at
temperatures as low as -20 deg C. http://link.abpi.net/l.php?20090804A13

WHITE PAPER
Approximately 57 percent of electric energy generated in the U.S. is
consumed by industrial electric motors. In response, motors, generators,
transformers and inductors are being designed to be more energy efficient
by utilizing thin gage silicon-iron. Some old and many new applications
use the advantages of thin gage laminations. This paper discusses how thin
gage silicon iron is beneficial, explains the theory in lay terms, and
shows the reader how to estimate an optimum lamination thickness.

QUESTION OF THE WEEK
Last week's question concerned airline travel. Two airlines - Spring
Airlines in China and Ryanair in Ireland - are now contemplating offering
standing-room-only flights, where seats would be replaced with
seatbelt-equipped barstool-type seats. This configuration would increase
capacity by as much as 40 percent and cut costs by about 20 percent, with
the savings presumably passed on to customers. We asked if you would take
a standing-room-only flight. Twenty-two percent of you said yes and
seventy-eight percent said no. Here's more of what you had to say:
"Absolutely not. As pilot and as passenger for nearly 60 years, I have too
much respect for unexpected air mass movement to not want to be in a secure,
comfortable position during flight." Norman Dalke
"Why not? Military Airlift Command (MAC) transported thousands of servicemen
in transport planes (C-141's) where the seat was nothing more than a
web-belt sling and a safety harness. If you have luggage, it just made for
a more comfortable seat." BTJW
"This seems like an idea for commuter flights. I don't think 25-45 minutes
would be much of an issue if you had a bar-stool type seat, then you could
put your carry-on bags underneath you. Most commuter flights have little
overhead space, and you plane-side check bags anyway. Now I wish they would
get smarter and deplane from forward-and-aft doorways to cut standing time."

This week's question revisits the government's "Cash for Clunkers" program.
The program, which gives owners of older, gas-guzzling cars and trucks
rebates of up to $4,500 to buy a new, more fuel-efficient vehicle, has
proved so popular with consumers the House of Representatives voted last
week to approve an additional $2 billion to continue the program. More
opposition may come from the Senate, expected to vote on the additional
funding shortly. Some opponents argue against subsidizing automobile sales
after the government bailed out General Motors and Chrysler; others claim
the program as now constituted falls short of promoting sales of fuel-
efficient vehicles. What do you think? Should the government continue the
"Cash for Clunkers" program? Yes or no? Submit your answer and post your
comments at: http://link.abpi.net/l.php?20090804A17
