The article surveys a research study by Jin Kon Kim and colleagues of Pohang University of Science and Technology and the LG Electronics Advanced Research Institute, who apply pressure to polymer films with probe tips to achieve nanoscale features for data storage. "The elegance of this process is that entropy (pressure) rather than enthalpy (heat) enables the writing to be done at room temperature.”
