  Grinding induced subsurface cracks in silicon wafers

  199971 · This paper presents the observation of subsurface cracks in silicon wafers machined by surface grinding process. Based on cross-sectional microscopy methods, several crack configurations are identified. Samples taken from different locations on the wafers are examined to investigate the effects of sample location on crack depth.

  Dissecting Tetra-N-phenylbenzidine: Biphenyl as the Origin …

  As the complexity of the system decreases with the molecule's size, spectroscopic investigation of this molecular family enables a deeper understanding of the appearance of RTP. With spectral and time-resolved measurements, RTP can be detected for all compounds containing a biphenyl core, with lifetimes up to 0.9 s under inert gas conditions.

  Hafting of Middle Paleolithic tools in Latium …

  2011104 · In this study, a dynamic threshold-based fuzzy adaptive control algorithm (DTbFACA) is proposed for hard sphere grinding to avoid scratches on the workpiece. The grinding force was indirectly obtained by measuring the motorized spindle current which was used as a feedback to control hard sphere grinding process.
