Depth-sensing indentation equipment is widely used for evaluation of the hardness and Young’s modulus of materials. The depth resolution of this technique allows the use of ultra-low loads. However, aspects related to the determination of the contact area under indentation should be cautiously considered when using this equipment. These are related to the geometrical imperfections of the tip, t...

In this paper, we reported a theoretical study of novel Surface plasmon resonance (SPR) biosensor composed BK7 prism, gold (Au)/silver (Ag) bimetallic layer, silicon and two-dimensional (2D) materials. The layer combines the advantages Au Ag high refractive index enhances electric field on surface sensor, so that sensor has better overall performance in terms sensitivity figure merit (FOM). Com...

The experimental setup shall compare face grinding with lateral in a single processing step using fused silica and BK7 as materials. Resin metal bonded tools are used strategies. paper presents the results order to deepen knowledge about those technologies further improve properties of fabricated components. Furthermore, confirm, that ultra-fine is technology, which can be process inorganic non...

The thermal stability of dielectric liquid lenses is studied by measuring the focal length at different temperatures. Two types of liquids lenses are investigated: Type-I (SL-5267/glycerol) and Type-II (glycerol/ BK7 matching liquid). A threshold-like behavior is found. Below the threshold temperature, the focal length is temperature insensitive. Above the threshold, the focal length changes ex...

We propose a joining process using femtosecond laser micro-welding to reinforce a direct bond. The process, which is executed at ambient temperature and can be applied to both similar and dissimilar material combinations, consists in inscribing weld lines in a closed loop forming a sealing pattern at the outskirts of the direct bond, thus preventing it from lifting off. We first characterized t...
