Zinc oxide (ZnO)-based varistor ceramic is a hard-to-machine material. Its microstructure, developed for its electrical properties, results in extremely low fracture toughness. Therefore, the current state-of-the-art machining this material lapping. In present work, laser-assisted milling (LAMill) of ZnO ceramics was evaluated with systematic approach to allow new insights and advance understan...

Laser-robots are well-established in the material processing industry. They are used for cutting, welding and marking of work pieces made from diverse materials. In these applications it is important to move the focal spot of the laser beam exactly along the desired machining contour on the work piece. Available laser sources are powerful enough to allow for very high machining velocities, whic...

Utilizing MATLAB to develop graphical user interface in modeling of machining responses is a very rare case among researchers, especially for the complex and nonlinear machining processes. Since it is more complicated and time consuming for one to explore artificial intelligent tools to model a process or response using MATLAB due to unfamiliarity and phobia of programming, a new approach is ve...

The importance of using techniques that allow the study of pure populations of cells has been increasingly recognized. The authors used laser-assisted microdissection (LAM) in combination with quantitative real-time PCR (qPCR) to assess the relative expression of mRNAs encoding estrogen receptor α (ERα) and progesterone receptor (PR) in the different compartments of the bovine oviduct (epitheli...

The acquisition of distinct cell fates is central to the development of multicellular organisms and is largely mediated by gene expression patterns specific to individual cells and tissues. A spatially and temporally resolved analysis of gene expression facilitates the elucidation of transcriptional networks linked to cellular identity and function. We present an approach that allows cell type-...

In laser drilling, an assist gas is often used to remove material from the drilling point. In order to design assist gas nozzles to minimize spatter formation, measurements of spatter trajectories are required. We apply computer vision methods to measure the 3D trajectories of spatter particles in a laser cutting event using a stereo camera configuration. We also propose a novel method for cali...

Abstract Additive manufacturing (AM) is a free-form technology that shows great potential in the integrated creation of three-dimensional (3D) electronics. However, fabrication 3D conformal circuits fulfill requirements high service temperature, conductivity and resolution remains challenge. In this paper, hybrid AM method combining fused deposition modeling (FDM) hydrophobic treatment assisted...

UV laser micro-machining of metallic materials has been used in microelectronic and other industries. Knowledge and-data about the process vary with feature size, material, laser wavelength and pulse duration. This paper carries out experimental and numerical investigation of micromachining of copper using a frequency tripled Nd: YAG laser with 50 nanosecond pulse duration. An axisymmetric mode...
