This numerical research presents a simple hybrid structure comprised of TiO-Cu-BaTiO for a modified Kretschmann configuration that exhibits high sensitivity and high resolution for biosensing applications through an angular interrogation method. Recently, copper (Cu) emerged as an exceptional choice as a plasmonic metal for developing surface plasmon sensors (SPR) with high resolution as it yields finer, thinner SPR curves than Ag and Au. As copper is prone to oxidation, especially in ambient conditions, the proposed structure involves the utilization of barium titanate (BaTiO) film as a protection layer that not only preserves Cu film from oxidizing but enhances the performance of the sensor to a great extent.

The cluster technique involves the creation of clusters and the selection of a cluster head (CH), which connects sensor nodes, known as cluster members (CM), to the CH. The CH receives data from the CM and collects data from sensor nodes, removing unnecessary data to conserve energy. It compresses the data and transmits them to base stations through multi-hop to reduce network load.

Effect of Cryo-Treated Cutting Tool End Milling on Custom 450 Stainless Steel.

Materials (Basel)

June 2023

Institute of Manufacturing Technology, Faculty of Mechanical Engineering, Brno University of Technology, Technicka 2896/2, 61669 Brno, Czech Republic.

Custom 450 stainless steel is the most desirable material across industries due to its widespread application in the aerospace, defense and marine industries. Stainless-steel materials are challenging to deal with and fall into the list of hard-to-process materials due to their low heat conduction coefficient and high mechanical properties. In this research work, end milling was carried out on Custom 450 stainless steel machined using TiAlN coated with tungsten carbide inserts that have been cryo-treated (CT) for 24 h (24 h) and 36 h (36 h), as well as untreated (UT) inserts.

Article Synopsis
  • Titanium nitride (TiN) thin film coatings were created on a silicon substrate using the atmospheric pressure chemical vapor deposition (APCVD) method to study how varying the deposition time impacts their characteristics.
  • Characterization techniques like scanning electron microscopy (SEM), atomic force microscopy (AFM), and nanoindentation were used to assess the coatings’ morphology, surface roughness, and mechanical properties.
  • Results indicated that longer deposition times resulted in increased surface roughness and enhanced mechanical properties (nanohardness and Young's modulus) while showing some imperfections like cracks and pores in the TiN structure.
