In this paper, Cu-Ti nanocomposite synthesized via ball milling of copper-titanium powders in 1, 3, and 6 of weight percentage compounds. The vial speed was 350 rpm and ball to powder weight ratio kept at 15:1 under Argon atmosphere, and the time of milling was 90 h. Obtained powders were studied by scanning electron microscopy (SEM), X-ray diffraction (XRD), and dynamic light scattering (DLS)....

This comment is on the paper ‘‘Piezoresistive Effect in SiOC Ceramics for Integrated Pressure Sensors’’, by Riedel et al. The experimental method of testing the piezoresistive behavior is flawed in this paper, as explained below. A similar flaw exists in Zhang et al. which is referenced by the subject paper. Due to this flaw, the piezoresistive results are not reliable. Piezoresistivity refers ...
