Intermittent origin of the large violations of the fluctuation dissipation relations in an aging polymer glass [PDF]
, 2003 The fluctuation-dissipation relation (FDR) is measured on the dielectric properties of a polymer glass (polycarbonate)in the range $20mHz - 100Hz$. It is found that after a quench below the glass transition temperature the fluctuation dissipation theorem

Quantifying the triboelectric series [PDF]
Nature Communications, 2019 AbstractTriboelectrification is a well-known phenomenon that commonly occurs in nature and in our lives at any time and any place. Although each and every material exhibits triboelectrification, its quantification has not been standardized. A triboelectric series has been qualitatively ranked with regards to triboelectric polarization.
