For sustaining my PhD thesis I need to publish 1 or more articles with ISI impact factor (total ISI value 5). I have the experimental results from my previous job and I don't have the possibility to publish trough institution, so I have to publish them myself. The field is (electro)chemistry with aplication for food analysis (MSG). Do you know any journals with low costs for publishing an article (maxim 150 $) or even free?
