Machined workpieces must satisfy quality standards such as avoid the presence of burrs in edge finishing to reduce production costs and time. In this work we consider three types burr that are determined by distribution shape on a microscopic scale: knife-type (without imperfections), saw-type (presence small splinters could be accepted) burr-breakage (substantial deformation produces unusable ...

Sharing data and code for reuse has become increasingly important in scientific work over the past decade. However, practice, shared may be unusable, or published results obtained from them irreproducible. Data repository features services contribute significantly to quality, longevity, reusability of datasets. This paper presents a combination original secondary analysis studies focusing on co...

The application of strain into GeSn alloys can effectively modulate the band structures, thus creating novel electronic and photonic devices. Raman spectroscopy is a powerful tool for characterizing strain; however, lack coefficient makes it difficult accurate determination in alloys. Here, we have investigated Raman-strain function Ge1-xSnxalong ?1 0 0? 1 directions. nanomembranes (NMs) with d...
