Tin research in thermoelectrics?

 

ITRI is sponsored by the worlds tin producers and has an opportunity to fund some research on tin in thermoelectrics.

However, we don't really know very much about potential use of tin in this application, or what the technology gaps might be?

Any comments or suggestions would be most welcome.

Many thanks

question about thermal conductivity calculation!

calculated the thermal conductivity using k =D Cp d, where D is measured by laser flash method, Cp is the specific heat capacity and d is the measured data using Archimedes method. Because when D is the value was measured by laser flash method, the effect of sample porosity on already included, If using the density d data measured by Archimedes method for the calculation of k, the effect of sample porosity will be doubled. is it right? However, it is widely used the experimental density. I will appreciate your answer!

Anatychuk At Odds With Official Research On Dental Amalgam

Research into the electrical behavior of metallic dental restorations has always simply ignored any effect of the thermoelectric properties of dental materials.


A typical example of this lapse in scientific rigor can be seen in the paper:


"The Role of Electrical Potential Differences in the Etiology of Chronic Diseases of the Oral Mucosa", János Inovay and Jolán Bánóczy, Journal of Dental Research, 1960.

Professor Anatychuk and Volta's Frog's Leg Experiments

For the benefit of any thermoelectricians who haven't read Professor Anatychuk's papers explaining the thermoelectric significance of Alessandro Volta's experiments with the dissected frog's legs more than 200 years ago, I've put them online at:

Efficiency of SiGe TE

Hi~

Recently, I am interested in the TE in the space applications. I know the SiGe material is most commonly used in high temperature situations. I want to know how could I calculate the efficiency of certain TE in certain temperature difference, such as 1300K and 750K? And between these temperatures, which TE has the highest efficiency?

Thanks!

Peltier by Thomson

Hi
What I understand is, Seebeck effect is just the first Thomson effect (Thermal gradient on single conductor creating an electromotive force) for the both conductors in thermocouple.

But how is Peltier effect explained with Thomson effect?

Second Thomson effect states that current on a conductor with thermal gradient makes one part of the conductor heat up and another part cool down due to the current being resisted or accelerated by the electromotive force created by the thermal gradient.

Looking for high perfomance thermoelctric material

Hello everybody,


Im looking for a high performance thermoelectric material in the temperature range of 100-150C.


Does anyone know such material?


Thanks,


Boaz
