    I found this science magazine summary, and I just don't quite understand how the electrocaloric effect works...

    http://www.sciencemag.org/cgi/conten.../5765/1209d?ct

    I found that basically consists on removing an applied magnetic field to certain type of films can produce a cooling effect.

    But... could anyone provide a better explanation of this?

    This article may be what you are looking for. I have not fully digested it myself. It focuses on the electropyrolitic effect, but discusses its relation to the electrocaloric.

    Yep... thanks.

    Electrocaloric effect is an inverse pyroelectric effect according to this, and the pyroelectric effect is very well explained here. Kind of overwhelming and considering I'm not a physicist, it'll take me some time to digest as you said.

    I am writing a paper about ozone disinfection. But in some of the references, there are some sentences using EC. It's like, the samples stored at 4EC for 10 days. What does that EC refer to? Is it electrocaloric temperature? If so, what does it mean? I am not a physysist by the way!
    Thanks in advance for any kind of information...

    I don't think it has nothing to do with electrocaloric effect. All I could think about is "Electrical Conductivity".

    Is the paper written in english? A little more context would be useful.

    Hi!
    Yes, the paper is in English. I'm writing the sentence as it is:

    Broiler gizzards were stored at 4EC for 10 days to obtain spoiled samples.

    ?

    I just can think of looking at www.acronymfinder.com and see if some definition for "EC" make any sense in the context of the paper... :?

    Could it be a misprint? 40 C? (With the degrees implied.)

    Other than that I have no idea. I looked at several sites on ozone disinfection and could see nothing that provided a possible match.

    It has to be!!!!!! I have just found some info as follows:

    temperature expressed in degrees Celsius (EC) or degrees Fahrenheit (EF); optimum. temperature for comfort is 22 to 24 EC (72 to 75 EF).


    !!!!!!!!!!!!! How confusing!!!! Thanks for helping!
