Carbon Nanotubes Outperform Copper Nanowires
as Interconnects
The shrinking size of computer chips has been stalled recently over
the complications of copper nanowire interconnects on the small scale,
which involve increased resistance and decreased conductivity. Current
research indicates that carbon nanotube bundles have the potential to
surpass nanowires in efficiency.

Expert Foresees 10 More Years to Make Solar
Energy Competitive
With oil prices hovering near 100 dollars per barrel, pressure to
establish a cleaner and more efficient fuel is increasing rapidly. Dr.
Harry Gray of the California Institute of Technology explains why solar
energy may take 10 more years to become a viable competitor with major
oil companies.

Air-filter regulator
 The Type-300 Gulf Buster Filter Regulator is
designed to stand up to harsh saltwater environments. The
aluminum-bodied regulator has stainless-steel parts that include trim,
internal construction (including internal valve stem), and external
hardware, including fasteners, drain valve, and adjusting stem.
The regulator comes in ¼-in. NPT porting and features 0 to 30, 0
to 60, and 0 to 100-psig output; 250-psig maximum supply pressure;
operates at –20 to 180°F; 20-scfm flow capacity at 100-psig supply
with 20-psig output; 0.1-scfm exhaust capacity with downstream 5 psig
above setpoint; and less than 5-scfh air consumption. Effect of Supply
Variation is less than 0.2 psig for 25-psig change.

Dc/dc converters for memory boards
 The 60-A-rated VCN60BADJTU-1C and 70-A-rated
VCN70BADjTU-1C are form-factor, point-of-load dc/dc converters that
deliver high efficiency and high current density for powering DDR1,
DDR2, and DDR3 memory and general-purpose ICs. The converters have an
approximate current density of 50 A/in.3 , 88% efficiency at
full load, 0.6 to 3.5-Vdc programmable output range with a typical
setpoint accuracy of 0.5%, and 12-Vdc input voltage. Features include
soft-start circuit, differential remote sense, power-good signal,
prebias turn on, and output enable, as well as overvoltage, overcurrent,
and overtemperature protection.

Miniature digital servodrive
 The Whistle 20A/100V is a series of
intelligent miniature digital servodrives for dc brush and brushless
motors, linear motors, and voice coils. The high-density device operates
on dc power and delivers 3.3-kW peak and 1,650 W of continuous power.
Features include intelligent SimpliQ core motion-control
technology and 20 A of continuous current. It is particularly useful in
applications with spatial limitations because of its PCB-mounted
design.

Rev up your interdisciplinary design skills
What happens when a microcontroller turns on a power FET, sending a
current pulse to a motor coil that develops a magnetic field which turns
the rotor shaft, advancing a timing belt that drives a pair of nip rolls
suspended on bearings in a web-processing operation on a form, fill, and
seal machine installed on a potato chip line at a Frito Lay plant in
central California? And how can you be sure that the encoders, prox
sensors, and other feedback devices you plan to use will accurately see
and report every relevant motion, machine state, and process condition?
And will the signals get through the networks fast enough, without being
corrupted, giving the controllers time to execute their algorithms as
intended? It's a lot to think about, and it only scratches the surface
of what many engineers grapple with today. If you happen to be one of
them, then the place for you — where you can find answers and meet
others with similar concerns — is www.Mechatronic-Design.com.
Backed by some of engineering's top information sources including

UPCOMING WEBCASTS
Multiphysics - More Than Just FEA
DATE: April 16th, 2008
TIME: 2:00pm ET/11am PT
Multiphysics capable simulation tools are revitalizing FEA, offering
smarter solutions to today's engineering problems. Sponsored by COMSOL,
this webinar introduces you to applying multiphysics modeling techniques
to solve design and production analysis problems. We will guide you
through three examples:
- Simulating friction-stir welding
- A molten aluminum extrusion-solidification process
- A live demo conducting a thermal-electrical-mechanical contact
analysis of a high power connector

Wireless Sensor Networks
A Surveer of Design Options
Sponsored by Winland Electronics Inc.
DATE: April 30th, 2008
TIME: 2:00pm ET/11am PT
Developing a wireless sensor network can be an awesome challenge or a
simple matter of picking the right module, depending on who you ask.
Off-the-shelf solutions have certain advantages, but may not be the best
overall solution to your problem. Home grown or custom solutions can be
designed to overcome specific challenges, so they can be critical for
certain projects. Learn more about the technical pros & cons of both
options in this live course.
