What is the Seebeck Effect

Similar to Christopher Columbus navigating the vast waters of the Atlantic, Thomas Seebeck helped to plot the way for the field of thermoelectrics. Seebeck’s discoveries in the 19th century have stood the test of time and continue to be used to this day.

Along with fellow physicists Jean Peltier of the Peltier effect and Lord Kelvin of the Thomson effect, Seebeck created the foundation for the field of thermoelectrics as we know it today.

What is the Peltier Thermoelectric Effect

NASCAR has Dale Earnhardt, cooking shows have Julia Child, and thermoelectrics has Jean Peltier. While his might not be a household name, chances are his discoveries and lasting legacy has reached you in some way. Peltier, a French physicist, is responsible for discovering what are now called thermoelectric coolers and heaters.

Power Adapters For Thermoelectric Coolers (TECS)

Thermoelectric modules and systems provide a solid state method to achieve programmable heating, cooling or temperature cycling by converting electrical power to heat pumping capability.  In thermoelectric applications, the power supply, or electrical power source, provides a DC current (Amps) at a regulated output, or working voltage (VDC).

II-VI Marlow Thermoelectric Module is on Mars

The Atlas V rocket thrusts the launch vehicle from the launch pad and propels it free of earth’s gravitational force and out into the dark and unforgiving environment of space. 254 days later the spacecraft begins a landing sequence that includes a steered free fall, a parachute descent, a rocket powered deceleration, then a tethered drop to the surface of the planet.

The launch date was 26 November 2011 and the vehicle within the spacecraft was the Mars Science Laboratory, aptly named Curiosity.

Thermoelectric Coolers are Advancing the PCR Process

The Ebola virus seems to be screaming from the headlines and is on everyone’s minds lately. The human death toll in Western Africa is tragic and each day’s news stories bring greater fears of it spreading. You may have heard about new disease detection techniques related to the Ebola virus and possibly even DNA amplification and cloning. What is not commonly known is the role thermoelectric coolers play in these headline-grabbing medical stories. Today’s blog provides a little background into biomedical technology, in particular, the process of polymerase chain reaction (PCR). II-VI Marlow supports this technology through the development and production of thermocycling products.

Improve Energy Efficiency with II-VI Energy Harvesting Technology

Replacing batteries is the bane of my existence.

They always seem to go dead right when I’m comfortably settled on my couch, or leave me stranded in an empty parking lot on the way home from work. The right size of batteries is never available when I need it. So, if I ever catch that dumb little Energizer bunny beating a drum … well, you get the point.

Welcome to II-VI Marlow, Leaders in Thermoelectric Technology

We started this blog as a forum intended to get our work out into the world, to communicate our projects and our successes. For most of the day, we're working heads-down on complex projects, and we rarely have the time to discuss or share with the community around us who can benefit from our discoveries. Our aim is to create an open dialogue in the thermoelectric community: to explain our processes, discuss new techniques and to share our company's wins.

Determining the Measurements of the Thermoelectric Figure of Merit

The transport properties of a solid includes the Seebeck coefficient (“S” in Volts per degree), the electrical conductivity (“s” in 1/(ohm-meters)) and the thermal conductivity (“l” in Watts per meter-Kelvin).  These three properties determine the thermoelectric figure of merit (Z) performance, Z º S2s/l, which has units of reciprocal temperature.

Better TE Materials for the Weather

“If you don’t like the weather, just wait a minute” and “Texas has four seasons, drought, flood, blizzard and twister,” are colloquialisms that well characterize the state of Texas weather. 

As Texas covers a large geographical area, the variations in weather or climate can be significant.  What about the variations in weather across the United States, or around the world?  And how about global warming?  Is it real?  Is it something we need to try to affect?  What are the facts and whose facts are correct?  While we at II-VI Marlow may not have the answers to the global warming questions and/or be able to solve the global warming issue with thermoelectrics, we certainly can assist the scientists and climatologists that are working on this issue.

Gas Turbine Waste Heat Recovery

Gas turbines are becoming increasingly popular in industrial production. Although gas turbines have decreased carbon emissions over the past 20-years, energy continues to be emitted externally and internally as exhaust. In fact, gas turbines generate 80% of all CO2 emissions from offshore activities.
